Sixty-six rabbits, with no history of vaccination against myxomatosis and which had died of pulmonary lesions, were submitted for virological and serological tests for Myxoma virus (MV) infection and for bacteriological examinations. At post mortem, the diagnoses based on observed lesions were as follows: acute haemorrhagic pneumonia (38%); acute suppurative bronchopneumonia (35%); and fibrinohaemorrhagic bronchopneumonia with fibrinous pleuritis (27%). MV was isolated from 10% of the rabbits, mainly from those with acute haemorrhagic pneumonia. Serological evidence of MV infection was demonstrated in 44% of rabbits. Pathogenic bacteria species isolated from lungs were Pasteurella (spp. and multocida), Escherichia coli, Bordetella bronchiseptica and Pseudomonas aeruginosa, respectively, from 41, 11, 7 and 6% of samples. No relationship could be established between the presence of specific antibodies to MV and the observed pulmonary lesions or the results of the bacteriological examinations. A significant trend was established between the severity of the lesions and the results of the bacteriological examinations. [less ▲]

Brucella spp. are Gram-negative, facultative intracellular bacteria that cause a zoonotic world-wide disease. As in other Gram-negative bacteria, its S-LPS (smooth lipopolysaccharide) is a major determinant of virulence. The Brucella melitensis 16M LPS O-antigen is a homopolymer of 4-formamido-4,6, dideoxymannose. In this study, the previously cloned 14-kb wbk gene cluster was sequenced, and seven open reading frames (ORFs) as well as four insertion sequences were identified. Six of the seven ORFs are homologous to LPS biosynthesis genes from other organisms. The gmd, per and wbkC gene products are predicted to be involved in 4-formamido-4,6,dideoxymannose synthesis. By deletion experiments, we demonstrated that the putative formyltransferase WbkC is absolutely required for the O-side-chain production. The wbkA gene product is similar to several mannosyltransferases and is probably involved in the polymerisation of the B. melitensis O-side-chain. We also identified two genes (wzm and wzt) encoding proteins with high similarity to several two-component ABC (ATP-binding cassette) transporters. Their implication in O-antigen translocation across the inner membrane was confirmed by gene replacement. Finally, no function has been assigned to the wbkB gene either by homology search or functionally, because deletion of wbkB did not interfere with the O-antigen structure. The seven ORFs have a low G + C content, indicating that they might have been acquired by lateral transfer from a progenitor with more A + T rich DNA. [less ▲]

The Hepatitis C virus (HCV) infects nearly 170 million people in the world. The major characteristic of virus C is its tendency to chronicity in more than 85% of cases. Generally asymptomatic, HCV infection may also evolve with time to cirrhosis and hepatocellular carcinoma. During the last few years, HCV-related end-stage cirrhosis has become the first cause of liver transplantation. In 10 years only, very significant progress has been made in the knowledge of the virus, not only in the field of diagnosis but also in therapy. Several consensus conferences taking last discoveries into account have been organized in order to promote recommendations useful for the management of hepatitis C patients. The aim of this short overview is to summarize practical recommendations that emerged recently from consensus meetings. [less ▲]

Para-clinical examinations in the diagnosis and treatment control of headache patients vary considerably between clinics and headache centers. Among the neurological societies in Europe there has been a consensus that some common procedures and recommendations should be created. In the Fall of 1998, the European Federation of Neurological Societies (EFNS) commissioned a Task Force on Neurophysiological Tests and Imaging Procedures in Headache Patients. Members of the Task Force are the present authors and we have reviewed the literature on 1) neurophysiological tests (EEG and evoked potentials), 2) autonomic nervous system and clinical tests and 3) imaging and cerebrovascular tests (X-ray, CT, MR, fMRI, PET, SPECT and transcranial Doppler). The literature was carefully evaluated with respect to validity and strength of the data. The task was to reach conclusions about each technique in the form of guidelines for clinical use. Finally, selected areas for future research will be outlined. The extensive review and the guidelines will be published by the EFNS during 2000. [less ▲]

The problem of columns submitted to fire is discussed in the intoduction with an emphasis on the differences between the case of a column acting as a single element or being part of a frame. In the latter case, failure of the column does not necessarily lead to the failure of the structure. The basic principles of the arc-length technique are given, first for the way it is applied traditionally at room temperature, then for the way it can be applied to extend a numerical simulation beyond the moment of local failures in case of fire. The technique is then applied to the case of restrained columns and it is shown how it is possible to obtain a safe estimate of the critical temperature of the column leading to the failure of the structure, even if the degree of restraint apllied to the column is unknown.

Two patients experienced episodes of acute pancreatitis shortly after starting treatment with interferon alfa-2b (IFN-alpha) for a chronic hepatitis C infection. The first patient was a 40-year-old man who developed acute pancreatitis after 15 weeks of treatment with 3 MU IFN-alpha subcutaneously (SC) 3 times weekly and 1200 mg ribavirin. After disappearance of symptoms and normalization of laboratory values, oral intake of solid foods and IFN-alpha therapy were restarted. Within hours, a relapse of acute pancreatitis occurred. A rechallenge with IFN-alpha 4 days later was followed by a prompt increase in serum lipase level, and IFN-alpha therapy was discontinued. The second patient was a 38-year-old man who developed acute pancreatitis 2 hours after SC administration of 5 MU IFN-alpha. Ultrasound endoscopy showed sludge in the gallbladder. The patient was rechallenged 5 weeks later with 3 MU IFN-alpha SC. Although serum amylase and lipase levels increased after readministration of IFN-alpha, treatment was continued. The patient was readmitted 2 weeks later with severe abdominal pain, and IFN-alpha administration was discontinued. Considering the temporal relationship between the start of IFN-alpha treatment and development of acute pancreatitis, the absence of other clear etiologic factors for acute pancreatitis, disappearance of symptoms after discontinuation of IFN-alpha, and positive reactions to rechallenge, IFN-alpha is the most probable cause for development of acute pancreatitis in these patients.

The clay mineralogy of Pleistocene sediments of eleven sediment cores at three ODP sites from 30 degrees N to 60 degrees N northwestern Atlantic Ocean has been investigated. The sediments are characterized by the presence of random illite-vermiculite mixed layers (I-V) (up to 32% of the clay mineral assemblage). The I-V clays are much more abundant during interglacial periods than during glacial ones. They are attributed to detrital supply through erosion of high-latitude continental areas from which they are derived mainly from chemical weathering of micaceous phyllosilicates. Their spatial distribution and the specific conditions for their formation through weathering suggest that I-V mixed layers are mainly derived from the Canadian Shield. They were transported From their source to marine deposition areas by rivers, deep water masses or nepheloid layers. Due to the specific conditions required For the Formation of I-V, its occurrence and abundance are used as a palaeoclimate and palaeocirculation proxy for northwestern Atlantic Pleistocene sediment.

OBJECTIVE: To examine erythropoiesis in renal transplant pregnancies. METHODS: Retrospective cohort study of 30 renal transplant cases and 30 age, smoking and parity-matched healthy controls with normal index pregnancy. Retrospective chart review and assay of frozen antenatal serum (for serum erythropoietin concentration [serum EPO]), transferrin receptor protein [TfR], ferritin, folate and B12) were performed. The linear regression equation for normal pregnancy controls was used to calculate predicted [serum EPO] and the observed/predicted (O/P) log [serum EPO] was plotted. The relationship between [serum EPO] and haemoglobin (Hb) among transplant cases was considered to be different from that among controls if the slope of the O/P log [serum EPO] versus Hb regression was significantly different from zero. RESULTS: The transplant (14 cadaveric) to conception interval was (median [range]) 33.5 [4, 189] months. Immunosuppressants were azathioprine (n = 25), cyclosporine (n = 22) and/or prednisone (n = 25). Cases were more often primiparous (20 vs. 7 [controls]; p = 0.01), had pre-existent hypertension (20 vs. 0 [controls]; p < 0.001), developed new/increased hypertension or pre-eclampsia (28 vs. 0 [controls]; p < 0.001) and an antenatal rise in creatinine (14 vs. 2 [controls]; p < 0.001). In early pregnancy, cases had similar EPO (15.2 [2.6, 84.6] vs. 15.7 [6.4, 41.0] [controls] U/L) but lower Hb (101 [65, 129] vs. 116 [106, 150] g/L; p < 0.001). Twenty-two (73%) cases had Hb < 100 g/L (vs. 4 [controls]; p < 0.0001); Hb was comparable at 6 wk postpartum. With advancing gestational age (GA), Hb remained stable and serum EPO increased in both groups. The slope of the O/P log [serum EPO] versus Hb for transplant cases was significantly different from zero within both the 17-28 wk (slope +/- SEM: 0.010 +/- 0.002; p < 0.0001) and the 29-42 wk GA categories (0.006 +/- 0.003; p = 0.02). Cases showed smaller rises in serum TfR (change 481 [- 1471, 2780]) vs. 1119 [- 698, 4195] [controls] ng/mL; p = 0.005). CONCLUSIONS: Anaemia frequently complicates renal transplant pregnancies, in which serum EPO is inappropriately low and the rate of erythropoiesis blunted. [less ▲]

Cell life depends on the dynamics of molecular processes: molecule folding, organelle building and transformations involving membrane fusion, protein activation and degradation. To carry out these processes, the hydrophilic/hydrophobic interfaces of amphipathic systems such as membranes and native proteins must be disrupted. In the past decade, protein fragments acting in the disruption of interfaces have been evidenced: they are named the tilted or oblique peptides. Due to a peculiar distribution of hydrophobicity, they can disrupt hydrophobicity interfaces. Tilted peptides should be present in many proteins involved in various stages of cell life. This hypothesis overviews their discovery, describes how they are detected and discusses how they could be involved in dynamic biological processes. [less ▲]

Various constraints can be encountered in partial differential problems. On the one hand, there are local constraints, which locally act on fields. These are usually boundary conditions, fixing components of fields, as well as interface conditions, connecting such components. On the other hand, global behaviors of fields can be constrained, leading to define global constraints. It is the case when vector field fluxes and circulations have to be defined, again in order to be either fixed or connected. A finite element model of a partial differential problem, through weak formulations, then leads to split up the considered constraints in two families, known as essential and natural constraints. This means that some constraints are strongly satisfied while others are only weakly satisfied. It is the aim of this paper to make a survey of local and global constraints encountered in finite element models of electromagnetic systems. It particularly points out the benefits of using both nodal and edge finite elements to achieve their consistent discrete definitions. There are indeed properties that are worth to be kept from the continuous to the discrete level. The constraints are defined in the frame of dual formulations in order to point out their dual, or complementary, natures. Systematic explicit characterizations of constrained function spaces are shown to be quite convenient. [less ▲]

We describe a naturally occurring dominant negative P2X1 mutant. This mutant lacks one leucine within a stretch of four leucine residues in its second transmembrane domain (TM2) (amino acids 351-354). Confocal microscopy revealed proper plasma membrane localization of the mutant in stably transfected HEK293 cells. Nevertheless, voltage-clamped HEK293 cells expressing mutated P2X1 channels failed to develop an ATP or ADP-induced current. Furthermore, when co-expressed with the wild type receptor in Xenopus oocytes, the mutated protein exhibited a dose-dependent dominant negative effect on the normal ATP or ADP-induced P2X1 channel activity. These data indicate that deletion of a single apolar amino acid residue at the inner border of the P2X1 TM2 generates a nonfunctional channel. [less ▲]

We describe the construction of an ovine BAC contig spanning a 4.6 centimorgan (cM) chromosome segment known to contain the callipyge (CLPG) locus. The contig comprises 21 ovine BAC clones jointly covering approximately 900 kilobases (Kb). Two gaps in the BAC contig, spanning 10 and 7.5 Kb, respectively, were bridged by long range PCR. The corresponding chromosome region was shown to be characterized by an unusually low Kb to cM ratio (164 Kb/cM) and a high density of Not1 sites (1:126 Kb) possibly reflecting a high gene density in the corresponding chromosome region. Equivalent amplification of 64 sequence tagged sites spanning the corresponding region from homozygous +/+ and CLPG/CLPG individuals disproves the hypothesis of a major deletion causing the CLPG mutation.

A method to improve the behavior of the numerical discretization of a rotated diffusion operator such as, for example, the isopycnal diffusion parameterization used in large-scale ocean models based on the so-called z-coordinate system is presented. The authors then focus exclusively on the dynamically passive tracers and analyze some different approaches to the numerical discretization. Monotonic schemes are designed but are found to be rather complex, while simpler, linear schemes are shown to produce unphysical undershooting and overshooting. It is suggested that the choice of an appropriate discretization method depends on the importance of the rotated diffusion in a given simulation, whether the field to be diffused is dynamically active or not.

The localization of protochorophyllide (Pchlide) and of NADPH-protochlorophyllide oxidoreductase (POR, EC 1.6.99.1) within (etio)chloroplasts has been investigated at selected stages of greening of barley seedlings. Pchlide pigment and POR protein contents were evaluated in different plastid membrane fractions by fluorescence spectroscopy and immunoblot analysis using a monospecific polyclonal antibody raised against the purified enzyme. Fluorescence analysis showed the presence of Pchlide in both the envelope and thylakoid membranes. During greening, the Pchlide content, expressed on a total protein basis, decreased in thylakoid membranes, whereas it increased in the envelope membranes. POR proteins were detected mainly in thylakoid membranes at early greening stages. In contrast, the weak amount of POR proteins was associated more specifically with envelope membranes of mature chloroplasts. Whatever the greening stage, thylakoid-bound Pchlide and POR proteins were more abundant in the thylakoid regions which remained unsolubilized after mild Triton treatment used as standard procedure to prepare PS II particles. This suggests the preferential association of Pchlide and POR to the appressed regions of thylakoids. [less ▲]

Systemic administration of nitroglycerin, a nitric oxide donor, triggers in migraineurs a delayed attack of unknown mechanisms. Subcutaneous nitroglycerin (10 mg/kg) produced a significant increase of nitric oxide synthase (NOS)- and c-fos-immunoreactive neurons in the cervical part of trigeminal nucleus caudalis in rats after 4 h. This effect was not observed in the thoracic dorsal horn. Similar increase of NOS and c-fos was obtained in the brain stem after a somatic nociceptive stimulus, i.e. on the side of the formalin injection in the lip. Nitric oxide is thus able to increase NOS availability in second order nociceptive trigeminal neurons, which may be relevant for central sensitization and the understanding of its effect in migraine.

Mitral valve repair has demonstrated its superiority over valve replacement. Mitral valve repair constitutes the optimal therapeutic option in case of degenerative dystrophic, rheumatic, congenital or ischemic mitral valve disease. These surgical techniques can also be successfully and advantageously applied in case of bacterial endocarditis or tumoral valvular disease. We report a case of staphylococcal endocarditis and another case of posterior leaflet fibroelastoma to show the place of conservative mitral surgery in these unusual indications. [less ▲]

BACKGROUND: The aim of the study was to investigate the consequence of warm and cold ischemia on lung mitochondria in order to define bioenergetic limits within lung could be suitable for pulmonary transplantation. METHODS: Twenty-two pigs underwent lung harvesting after lung flush with Euro-Collins solution. Mitochondria were isolated from fresh lungs, from lungs submitted to 24 or 48 hr of cold ischemia, to 30 or 45 min of warm ischemia, and to 30 min of warm ischemia followed by 24 or 48 hr of cold ischemia. Mitochondrial oxidative phosphorylation parameters were determined in isolated mitochondria by in vitro measurement of oxygen consumption. RESULTS: Relative to controls, mitochondria submitted to cold ischemia showed an alteration in the oxidoreductase activities of the respiratory chain but no membrane permeability alteration. After 48 hr of cold ischemia, there was a decrease in the yield of the oxidative phosphorylation. Thirty minutes of warm ischemia did not alter the mitochondrial respiratory parameters. However, lung submitted to 45 min of warm ischemia showed mitochondrial damage as a decrease in the oxidative phosphorylation efficiency and ADP availability but no change in the oxidoreductase activities. Relative to cold ischemia alone, 30 min of warm ischemia preceding cold ischemia promoted no significant change in the respiratory parameters. CONCLUSIONS: On bioenergetic basis, lung submitted to warm ischemia could be suitable for transplantation if the warm ischemia duration does not exceed 30 min. This could be a major concern in lung procurement from non-heart beating donors. [less ▲]

Eosinophilic bronchopneumopathy was diagnosed in 23 young dogs. Clinical signs included cough, gagging, and retching in all dogs, dyspnea in 21 dogs (91%), and nasal discharge in 12 dogs (52%). The most common radiographic findings were a moderate to severe bronchointerstitial pattern (68%, 13 of 19 dogs). Bronchoscopic findings included the presence of abundant yellow-green mucus or mucopurulent material (70%, 16 of 23 dogs) and severe mucosal thickening with an irregular or polypoid appearance (52%, 12 of 23 dogs), with partial airway closure during expiration in 3 dogs (13%). Peripheral blood eosinophilia was noted in 14 of 23 dogs (61%). Inflammatory cells in brush or bronchoalveolar lavage fluid cytologic preparations comprised more than 50% eosinophils in 14 of 23 dogs (61%), and 20-50% eosinophils in 6 dogs (26%). Eosinophilic infiltration of the bronchial mucosa was observed in biopsies from 19 dogs and was graded as mild (37%, 7 dogs), moderate (32%, 6 dogs), or severe (32%, 6 dogs). The mean serum immunoglobulin A concentration was almost double that of a population of 20 healthy dogs of various breeds. Oral glucocorticoids were administered on alternate days with progressive tapering of the dose; the dosage at maintenance varied between 0.1 and 1.0 mg/kg every other day. No relationship was found between the duration of clinical signs and the maintenance dosage or the cytologic and histopathologic grades. [less ▲]

Ischaemic colitis following aortoiliac surgery is a feared complication. Its frequency varies from 7% after repair of ruptured abdominal aortic aneurysm (AAA) to 0.6% after bypass for aortoiliac occlusive disease (AOD). In order to analyse predisposing factors and outcome of ischaemic colitis, the authors reviewed their clinical experience from 1988 to 1998. It concerns 28 cases (16 ruptured AAA, 7 elective AAA, 5 OAD) of clinically evident colonic ischaemia. This means an incidence of 7% after repair of ruptured AAA, 0.6% after elective AAA repair, and 0.8% after bypass for AOD. Transmural necrosis (grade 3) was observed in 21 patients, grade 2 ischaemia in 5 patients, and grade 1 ischaemia in 2 patients. Fifteen patients with grade 3 ischaemia underwent colectomy (Hartmann's procedure) with a mortality rate of 66%. All non operated grade 3 patients died. Overall, 16 of the 28 patients died at hospital (57% mortality rate). None of the patients with mild (grade 2 or 1) colonic ischaemia died. Profound hypovolaemic shock and inflammatory AAA were the only significant predisposing factors leading to colonic ischaemia. Associated colon revascularization could not avoid the evolution to colon necrosis in four patients. Reimplantation of a patent inferior mesenteric artery or an internal iliac artery was performed in only 4.8% of all aortoiliac reconstructions, and did not influence the development of ischaemic colitis. The authors conclude that a more liberal use of postoperative sigmoidoscopy could allow detecting colonic ischaemia at an earlier stage and reduce ensuing mortality. A reinforced effort to restore or preserve colonic vascularization could lower the incidence of colonic ischaemia following aortoiliac surgery. [less ▲]

BACKGROUND: In 1998, ICPC-2 was published as a book. In the process of translating the book, and preparing an electronic version of chapter 10 (the actual classification), ICPC-2 proved to contain many errors and inconsistencies. Particularly, major problems were identified in the conversion between ICPC-2 and ICD-10, which could lead to major errors when used in electronic patient records. OBJECTIVES: We prepared an electronic version of chapter 10 of ICPC-2, ICPC-2-E, with all necessary corrections, to be published on the Oxford University Press web site as a part of this article. METHODS: Errors and inconsistencies were redressed, including particularly those in the con-version structure with all consequences on the level of inclusion and exclusion criteria, through a process of careful checking. RESULTS AND CONCLUSION: ICPC-2-E, the electronic version of chapter 10 of ICPC-2, is specifically to be used in an electronic patient record and for research purposes. It is to be used together with the first nine chapters of ICPC-2, since the book is indispensable to make a correct use of ICPC. [less ▲]

The functional role of the calcium-binding proteins parvalbumin, calretinin, and calbindin D-28k for epileptogenesis and long-term seizure-related alterations of the hippocampal formation was assessed in single- and double-knockout mice, using a kainate model of mesial temporal lobe epilepsy. The effects of a unilateral intrahippocampal injection of kainic acid were assessed at one day, 30 days, and four months post-injection, using various markers of GABAergic interneurons (GABA-transporter type 1, GABA(A)-receptor alpha1 subunit, calretinin, calbindin D-28k, somatostatin, and neuropeptide Y). Parvalbumin-deficient, parvalbumin/calbindin-deficient, and parvalbumin/calretinin-deficient mice exhibited no difference in cytoarchitecture of the hippocampal formation and in the number, distribution, or morphology of interneurons compared to wild-type mice. Likewise, mutant mice were not more vulnerable to acute kainate-induced excitotoxicity or to long-term effects of recurrent focal seizures, and exhibited the same pattern of neurochemical alterations (e.g., bilateral induction of neuropeptide Y in granule cells) and morphogenic changes (enlargement and dispersion of dentate gyrus granule cells) as wild-type animals. Quantification of interneurons revealed no significant difference in neuronal vulnerability among the genotypes.These results indicate that the calcium-binding proteins investigated here are not essential for determining the neurochemical phenotype of interneurons. Furthermore, they are not protective against kainate-induced excitotoxicity in this model, and do not appear to modulate the overall level of excitability of the hippocampus. Finally, seizure-induced changes in gene expression in granule cells, which normally express high levels of calcium-binding proteins, apparently were not affected by the gene deletions analysed [less ▲]

The effect of residual fat hydrolysis upon the gelation of whey protein concentrate (WPC) was studied. Gelling properties of a commercial WPC and lipase-treated WPC were evaluated on the basis of least concentration endpoint gelation, penetration test, texture profile analysis and water-holding capacity. Heat treatment of lipase-treated WPC led to gels with the highest hardness, springiness, cohesiveness and water retention. Such transformed WPC could be advantageously used to help improve texture in formulated meat, bakery, and confectionery products. [less ▲]

The surface composition of alloy particles in Pd-Ag/SiO2 hydrodechlorination (HDC) sol-gel catalysts has been determined by combining three experimental techniques, carbon monoxide chemisorption, X-ray diffraction, and transmission electron microscopy, Values obtained through this method show a very marked silver enrichment of the surface, as expected: as a consequence of the important gap between palladium and silver surface energies. These values are in complete agreement with surface composition curves calculated in other studies by means of Auger electron spectroscopy and infrared spectroscopy. The influence of sample pretreatment temperature as well as the influence of carbon monoxide on surface composition are discussed. (C) 2000 Academic Press. [less ▲]

OBJECTIVE: To study the levels of matrix metalloproteinase-3 (MMP-3) in the knee synovial fluid (SF) of inflammatory arthropathies (rheumatoid arthritis whether erosive or not, reactive arthritis, acute crystal arthritis) and degenerative arthropathies [chronic crystal disease, osteoarthritis and (control) meniscus pathology] and to correlate them with the degree of joint destruction, local inflammatory and immune parameters and systemic markers of inflammation. METHODS: SF levels of MMP-3 (precursor, active and tissue inhibitor of MMP-bound forms), tumour necrosis factor (TNF) alpha, soluble TNF receptors I and II, interleukin (IL)-6 and soluble IL-6 receptor were measured by ELISA in 107 inflammatory and 53 degenerative arthropathies. RESULTS: MMP-3 levels in SF were (i) significantly higher in inflammatory than in degenerative arthropathies; (ii) not related to the degree of joint destruction; (iii) significantly correlated with the levels of all SF markers tested and with erythrocyte sedimentation rate and serum levels of C-reactive protein and fibrinogen. CONCLUSION: Increased MMP-3 levels in SF are found in inflammatory arthropathies and are not specific for erosive joint diseases. MMP-3 in SF is therefore a potential candidate for the assessment of the inflammatory process in joints. However, the exclusive determination of the active form could indicate the degree of joint destruction. [less ▲]

In teleosts, feeding is effected principally by suction and food is handled by the branchial basket. Preys are carried to the oesophagus by the pharyngeal jaws (PJs). The pharyngobranchial bones constitute the upper pharyngeal jaws (UPJs) and the 5th ceratobranchial bones, the lower pharyngeal jaws (LPJs). In lower teleosts, these jaws have well-separated spindly parts attached to the neurocranium, pectoral girdle, and hyoid bar; they only transport food and LPJ activity predominates. In acanthopterygians, the PJs become stronger, the left and right ceratobranchials fuse into one LPJ, and the pharyngobranchials join together to form two big UPJs articulating with the neurocranium. In labrids and scarids, the LPJ is also joined to the pectoral girdle. In acanthopterygians, a new retractor dorsalis muscle gives the UPJs the major role in food chewing and transport. Cypriniforms have developed original PJs with strong 5th ceratobranchials opposed to a postero-ventral neurocranial plate. Small-sized preys and food particles are seized by the gill rakers, small skeletal pieces supported by the branchial arches. [less ▲]

We reviewed 355 nerve biopsies analysed at the Laboratories of Neuropathology of the Born-Bunge Foundation/University of Antwerp (BBF/UIA) and University of Liege (ULg) between 1987 and 1997. We examined the indications for nerve biopsy, the yield of the procedure, and the influence of clinical and neuropathological parameters. Contributory biopsies accounted for 35.5% and 47.3% respectively at ULg and BBF/UIA laboratories: of these, one third showed specific histological findings, the majority being informative only when combined with the relevant clinical data. The profile of indications for nerve biopsy was roughly comparable in both laboratories. The search for an inflammatory neuropathy prompted 35-40% of all biopsies with more than 50% of specimens being informative in this indication. The lowest yield (20%) was obtained among the nerve biopsies performed in the absence of any presumptive aetiology. These accounted for 22-33% of all cases. Inadequate surgical resection, delays in transport or processing errors precluded histological study of 4% (BBF/UIA) to 8% (ULg) of the specimens. We conclude that nerve biopsies should be performed by experienced surgeons and handled in specialised laboratories. Only a relatively small number of causes of neuropathy can be diagnosed on the basis of histology alone. More often, contributory biopsies will result from the combination of non-specific suggestive histological features with relevant clinical information. The diagnostic yield of nerve biopsy is function of careful patient selection and close collaboration between the clinician and the neuropathologist. [less ▲]

The effect of ammonia on the C-fibre which is involved in the citric acid induced coughing reflex was assessed. The piglets were exposed during a period of 24 hours or 4 days to a concentration of 15 or 30 ppm ammonia in an inhalation chamber . During this challenge, the animais underwent cough induction tests at two days intervals. Another group was exposed to ammonia (30 ppm) for 48 hours, after this period, substance P was assayed in liquids collected from broncho-alvealor and tracheal washings (BAL and TAL) and in tracheal and airway mucosa . Ammonia (30 ppm) induced an inhibition 0f the coughing reflex in pigs. The minimum period of exposure necessary to provoke this effect was 48 hours. The same ammonia concentration aiso induced o significant increase in substance P concentrations in BAL and TAL and a significant decrease in concentrations of the tracheal mucosa. We conclude that ammonia at o concentration of 30 ppm inhibits the citric acid induced coughing reflex. The effect was partly mediated by the release of substance P from the C-fibre. [less ▲]

In general, muscular exertion occurs when there is oxygenation of the energy substrates carbon hydrate and fatty acids. At the beginning of exercise and/or when there is extra exertion, anaerobic metabolism also participates in the synthesis of ATP, which is essential for muscular contraction. The organism's oxygen consumption is proportional to the intensity of the effort, except during anaerobic metabolism. The maximum quantity of substrates that can oxygenate the muscles per unit time depends on the enzymatic material available. When the total aerobic capacity is used, the oxygen consumption is said to be maximal. The oxygen consumed at cellular level is taken from the ambient air at the areas of pulmonary exchange and transported throughout the body by the cardiovascular system. It is therefore essential that there is sufficient functional ability to adapt to cardiovascular and respiratory changes in order to ensure adequate O2 and nutrient transport and evacuation of CO2 and heat. The two systems adapt with exercise and training [less ▲]

This study has two principal objectives. The first objective is to measure and compare the performance of European railways. The second objective is to illustrate the usefulness of econometric distance functions in the analysis of production in multioutput industries, where behavioural assumptions such as cost minimization or profit maximization, are unlikely to be applicable. Using annual data on 17 railways companies during 1988± 1993, multioutput distance functions are estimated using corrected ordinary least squares (COLS). The resulting technical efficiency estimates range from 0.980 for the Netherlands to 0.784 for Italy, with a mean of 0.863. The distance function results are also compared with those obtained from single-output production functions, where aggregate output measures are formed using either total revenue or a Tornqvist index. The results obtained indicate substantial differences in parameter estimates and technical efficiency rankings, casting significant doubt upon the reliability of these single-output models, particularly when a total revenue measure is used to proxy aggregate output.

The hypothesis that growth hormone (GH) can affect immune responses in man has been evaluated by monitoring cytokine expression in cultures from peripheral blood mononuclear cells, by enzyme-linked immunosorbent assay (ELISA) and ribonuclease protection assay, and in tonsillar cells by ELISA. In addition to pituitary GH (GH-N), the placental form (GH-V), differing from pituitary GH by 13 amino acids has also been tested. Only few effects reached statistical significance and were in no case greater than 15%. Pituitary GH slightly reduced IL-5 production and stimulated IFN-gamma production. The latter effect was also observed with prolactin and could thus be induced through the prolactin receptor. It is proposed that GH has no strong effects on the parameters investigated, possibly as a result of redundancy in the cytokine network. Alternatively, effects on leukocytes are mediated by other tissues such as the liver or are clear only in response to stronger challenges. [less ▲]

This study examined the ability of near infrared spectroscopy (NIRS) to noninvasively determine changes to muscle oxygenation in the resting horse. Five horses had (NIRS) performed over extremity muscle while under general anaesthesia, first with 8 min limb ischaemia, then systemic hypoxaemia for 5 min. A second group of 6 awake horses had NIRS performed over extremity muscle while being administered hypoxic gas (F(I)O2 0.10) for 5 min, and after return to steady state, limb ischaemia was induced for an additional 5 min. In the anaesthetised horses' ischaemia induced marked and significant muscle deoxygenation of haemoglobin/myoglobin (P<0.01), with corresponding arterial saturation decreasing from 98.9 to 81.9%. Hypoxaemia induced small yet significant muscle deoxygenation (P<0.01) that was 3.2% of the ischaemia deoxygenation signal, with a corresponding decrease in arterial saturation from 98.6 to 90.4%. In the awake horses muscle deoxygenation was not detectable during hypoxia despite reduction of arterial saturation from 97.8 to 86.8%, whereas ischaemia induced rapid and significant deoxygenation of muscle (P<0.05), with corresponding reduction of venous saturation from 78.4 to 75.4%. In neither group of horses was there evidence of cytochrome aa3 reduction, despite complete ischaemia for up to 8 min. NIRS changes in the resting horse muscle clearly differed between ischaemia and hypoxaemia, and can readily show muscle deoxygenation in clinically relevant hypoxaemia in the horse under anaesthesia. Further, as the deoxygenation signal induced by ischaemia was clearly detectable above a background movement artefact, NIRS application to study of muscle oxygenation in the working horse should be explored.

The eggs of some ladybirds are known to be toxic to intraguild ladybird predators. However, this defence is of little value if the eggs are killed before their toxicity becomes apparent. The results presented in this paper indicate that chemicals on the surface of the eggs of two species of ladybirds signal the relative risk of cannibalism and intraguild predation. In Adalia bipunctata and Coccinella septempunctata, 87% of the chemicals are alkanes. Each species of ladybird is less reluctant to eat their own eggs than those of the other species. This asymmetry is to be expected because there is a greater risk to ladybirds from intraguild predation than cannibalism. Similar alkanes to those on the surface of the eggs of A. bipunctata are present in tracks left by larvae and on the elytra of the adults of this species. Those in the larval tracks deter females from ovipositing in patches of prey already being attacked by their larvae and those on the elytra are used in mate recognition. That different context dependent messages could be signalled by similar chemicals is an example of semiochemical parsimony. [less ▲]

Aortobronchic fistula is a very unusual complication of thoracic aneurysm. We report the case of a 71-year old man with rupture of a thoracic aortic aneurysm in the left main bronchus. The patient had suffered a car crash fifteen years ago, without any evidence of aortic rupture at the time. Thereafter, he developed an aortic isthmic dilation (36 mm in diameter). The patient suffered from long standing pulmonary insufficiency and emphysema and was admitted several times on an urgent basis for acute dyspnea. During an hospitalization for respiratory distress, he presented haemoptysis and left lung hyperinflation secondary to partial fistulization and extrinsic compression of the main left bronchus. Isthmic aortic resection and prosthetic grafting was performed and the left main bronchus was closed by an autologous pericardial patch. Ten days later, following an air-leak from the bronchial closure, a transposed latissimus dorsi flap was used by the plastic surgeon to repair the defect. Nevertheless, the patient died from multisystemic failure six weeks later. [less ▲]

To counteract the wasteful use of good quality farmlands by other land uses, we have developed a quantitative method for land evaluation. By splitting up soil map symbols, we have drawn up suitability maps for cultivation and for grazing. Farming factors, such as slope, closeness to the farmhouses and size of the farmland blocks, were integrated in the soil suitability map with the help of a geographic information system. The multiplication of the weighted coefficients linked to these factors lead to a global farmland evaluation map. This method has been tested in 10 districts of the Walloon Region. Results seem to be close to farmers practices. The validation problems of this map and the benefits of a factorial and quantitative method are also discussed in this paper. [less ▲]

Alzheimer's disease is characterized by early hippocampal lesions, but neuropathological and functional imaging studies have also demonstrated involvement of associative cortices in patients suffering from this illness. New image-processing technologies have led to demonstration of predominant posteromedial cortical metabolic impairment in the disease. Confounding effects of both age and dementia severity on brain metabolism were assessed using categorical and correlational analyses performed with Statistical Parametric Mapping. Posterior cingulate and precuneus metabolism, assessed by positron emission tomography, was significantly correlated with age in a population of 46 patients with probable Alzheimer's disease. Metabolism in posterior cingulate and precuneus was higher in elderly than in younger patients with a diagnosis of Alzheimer's disease, even when dementia severity was taken as a confounding covariate. The data suggest that the sensitivity of positron emission tomography for the diagnosis of Alzheimer's disease is reduced in elderly cases, where less severe pathology is sufficient to induce clinical symptoms of dementia. Conversely, higher posteromedial metabolic impairment in early onset cases may reflect greater density of regional cerebral lesions or major decrease of functional afferences in a richly connected multimodal associative area. Posterior cingulate metabolism was also correlated to dementia severity, even when age was taken as a confounding covariate, whereas metabolism in the hippocampal formation was not shown to correlate with global cognitive deficit. Functional correlation was maintained between posterior cingulate and middle frontal cortex in demented patients as in elderly controls. The key role of posteromedial cortex in cognitive dysfunction assessed in Alzheimer's disease is probably related to its highly integrated position within attentional, visuospatial and memory neuronal networks.

Insulin-like growth factor-I and -II (IGF-I, IGF-II) circulate in biological fluids bound to six different IGF-binding proteins that regulate IGF bioactivity. The IGF-binding protein-2 is regulated by growth hormones, and its concentration depends on nutrition and physiological state. Specific antibodies directed against bovine IGF-binding protein-2 were produced, and IGF-binding protein-2 levels in bovine blood samples were quantified by radioimmunoassay. Parallel displacement curves showed strong cross-reactivity with bovine and ovine plasma, were low with porcine plasma, and no cross-reactivity with rat or chicken plasma. Addition of IGF-I or -II to a control pool of bovine plasma did not significantly alter control IGF-binding protein-2 values in a radioimmunoassay. Six nycthemeral periods, determined for three young bulls bled on two occasions, showed that IGF-binding protein-2 plasma levels were stable throughout the day; two or three samples were sufficient to characterize the animal. Cows treated with recombinant bovine somatotropin (bST) had significantly lower serum levels of IGF-binding protein-2 than did control cows. Furthermore, IGF-binding protein-2 levels were dramatically increased at the onset of lactation. This radioimmunoassay for bovine IGF-binding protein-2, which enables quantitative assessment of IGF-binding protein-2 concentration in cattle, confirmed that IGF-binding protein-2 concentrations are depressed by administration of bST, enhanced after calving, and showed absence of diurnal variation.

Une étude récente (1999) de la végétation, de la variation du niveau de la nappe aquifère et des caractéristiques de la tourbe sous-jacente, à la périphérie de la tourbière active du Misten permet d'entrevoir l'époque la plus probable d'exploitation de la tourbe dans la région de cette tourbière. Un calcul de la vitesse d'accumulation récente de la tourbe à différentes zones à la périphérie de la partie active de la tourbière a été effectué par des sondages de tourbe rapprochés et analysés finement au niveau palynologique. On constate que la vitesse d'accumulation de la tourbe varie selon les profils distants de 10m les uns des autres et que celle-ci diminue au fur et à mesure que l'on se rapproche du bord actuel de la tourbière active. A l'aide d'une datation au carbone 14, nous pouvons avancer que la date de l'altération du bord sud-est de la tourbière active du Misten a dû commencer vers 1330 AD (1170 + 160), soit bien antérieurement au creusement du fossé d'Eupen (1774), mais aussi bien avant les premières exploitations de tourbe connues dans les fagnes de Sourbrodt.

Respirometric tests have been undertaken on sediments in aerated lagoons and waste stabilization ponds to quantify their oxygen demand and to determine the main factors governing the process. Factors such as seasonal variations, temperature, substrate, sediment layer thickness, density of macro-invertebrates and suspended sediments were investigated. The results showed that temperature and substrate concentration are the main factors that influence sediment oxygen demand; followed by spatial heterogeneity and resuspension of sediments, whereas the density of macro-invertebrates could have an effect in summer (hot season). Sediment layer thickness had no effect. A model of sediment oxygen demand is developed for the two main factors (temperature and substrate) with an r2 of 0.98. [less ▲]

Objective: To present data from a series of 17 cases of bladder endometriosis. Design: Clinical study. Setting: A university hospital department of gynecology. Patient(s): Seventeen patients complaining of menstrual urinary symptoms and/or pelvic pain. Intervention(s): Diagnosis and resection of a bladder adenomyotic nodule. Main Outcome Measure(s): Histologic analysis and postsurgical outcome. Result(s): Seventy-six percent of the patients reported menstrual mictalgia and pollakiuria, and 88% reported dysmenorrhea and dyspareunia. Cystoscopy, intravenous pyelography, and magnetic resonance imaging revealed a nodular mass in the anterior fornix adjacent to the uterine wall, developed in the vesical muscularis and involving the vesical mucosa in all cases but one. The bladder nodule was associated with a rectovaginal nodule in six cases (35%). Because recurrence was noted soon after cessation of medical therapy, surgical excision was proposed. The vesical mucosa was found to be intact in almost all cases, so extramucosal laparoscopic excision was the method of choice. Histologic examination proved that 90% of the nodule consisted of smooth muscle hyperplasia. Conclusion(s): So-called bladder endometriosis is actually an adenomyotic nodule of the bladder which, from a histologic point of view, is similar to a rectovaginal adenomyotic nodule and frequently (35%) associated with it.

H(2)(15)O-PET was used to investigate changes in regional cerebral blood flow in response to auditory stimulation in patients in the vegetative state. Five patients in a vegetative state of hypoxic origin were compared with 18 age-matched controls. In addition, the cerebral metabolism of these patients and 53 age-matched controls was studied using [(18)F]fluorodeoxyglucose. In control subjects, auditory click stimuli activated bilateral auditory cortices [Brodmann areas (BA) 41 and 42] and the contralateral auditory association cortices (BA 22). In the patients, although resting metabolism was decreased to 61% of normal values, bilateral auditory areas 41 and 42 showed activation as seen in the controls, but the temporoparietal junction cortex (BA 22) failed to be activated. Moreover, the auditory association cortex was functionally disconnected from the posterior parietal association area (BA 40), the anterior cingulate cortex (BA 24) and the hippocampus, as revealed by psychophysiological interaction analysis. Thus, despite altered resting metabolism, the auditory primary cortices were still activated during external stimulation, whereas hierarchically higher-order multi- modal association areas were not. Such a cascade of functional disconnections along the auditory cortical pathways, from the primary auditory areas to multimodal and limbic areas, suggests that the residual cortical processing observed in the vegetative state cannot lead to the integrative processes that are thought to be necessary for the attainment of the normal level of awareness.

Effect of forest canopy on the accuracy of a differential global positioning system (dGPS). The possibilities to use dGPS for forest mapping are analysed. The efficiency of dGPS in forest condition is linked to canopy interference, which intercepts signals sent by some of the satellites or reflect them (multipathing). Two types of equipment have been tested : a TrimbleTM Svee Six coupled with a RDS differential receiver and a Trimble SK8 coupled with an OMNISTAR differential receiver. Recordings have been achieved according to two modes : static (recording on one spot during one minute) and cinematic (moving continuously along the stand limits). Two types of forest canopy were compared : light canopy made of young poplar plantation with few obstacles in the vicinity, and closed canopy of mature spruce stand edged with other mature stand. Cinematic mode efficiency is higher than static one (mean errors are respectively 3.1 m and 9.1 m). In the same way positioning is more accurate for the stand with light canopy than for the other one (mean errors are respectively 2.9 m and 9.4 m). Difference between recording modes are probably due to multipathing effect that filtering algorithm integrated in the GPS receivers are not able to remove in static mode. The efficiency of differential signal reception is also different for the two stands : 1.3 % and 20.5 % of missing differential signal respectively in the light and dense canopy conditions. [less ▲]

A simple method for predicting residues involved in protein interaction sites is proposed. In the absence of any structural report, the procedure identifies linear stretches of sequences as "receptor-binding domains" (RBDs) by analysing hydrophobicity distribution. The sequences of two databases of non-homologous interaction sites eliciting various biological activities were tested; 59-80 % were detected as RBDs. A statistical analysis of amino acid frequencies was carried out in known interaction sites and in predicted RBDs. RBDs were predicted from the 80,000 sequences of the Swissprot database. In both cases, arginine is the most frequently occurring residue. The RBD procedure can also detect residues involved in specific interaction sites such as the DNA-binding (95 % detected) and Ca-binding domains (83 % detected). We report two recent analyses; from the prediction of RBDs in sequences to the experimental demonstration of the functional activities. The examples concern a retroviral Gag protein and a penicillin-binding protein. We support that this method is a quick way to predict protein interaction sites from sequences and is helpful for guiding experiments such as site-specific mutageneses, two-hybrid systems or the synthesis of inhibitors.
