Bovine herpesvirus type 4 (BHV-4) is a ubiquitous herpesvirus in cattle. It has been isolated from animals showing a wide variety of clinical signs but few of the isolates have proven experimental pathogenicity. Species that are susceptible to BHV-4 include animals other than ruminants, notably cats and, surprisingly, a primate the owl monkey (Aotus trivirgatus). BHV-4 exists as a latent infection in mononuclear cells. In cattle, BHV-4 has been isolated in animals exhibiting ocular and respiratory conditions and it has been found in females with genital tract conditions such as post-partum metritis and vulvovaginitis. There is some epidemiological and experimental evidence that BHV-4 may be a cause of bovine abortion. There is no vaccine available in Europe and prevention is exclusively by hygiene measures.

Sm-Nd studies were carried out on Last Glacial and Holocene sediments from the Labrador Sea. Three grain-size fractions were analyzed for each sediment: the clay-size fraction (<2 mu m), the fine cohesive silts (2-10 mu m) and the coarse silts (10-63 mu m) In most cases, Sm-Nd signatures are different from one grain-size to another. In addition, different Sm-Nd signatures are derived from the clay-size fractions compared to the cohesive silt fraction, indicating that the cohesive fraction is heterogeneous and that distinct origins in terms of source-areas are implied. Silt fractions record the influence of supplies from the North American Precambrian Shield, whereas clay-size fractions (<2 mu m) are more sensitive to sedimentary input from the Eastern Basins, in relation with deep currents. Coupling Sm-Nd studies on silt and clay fractions may be a powerful tool to unravel the evolution of deep circulations versus detrital supplies. (C) 2000 Elsevier Science B.V. All rights reserved.

Translating linear temporal logic formulas to automata has proven to be an effective approach for implementing linear-time model-checking, and for obtaining many extensions and improvements to this verification method. On the other hand, for branching temporal logic, automate-theoretic techniques have long been thought to introduce an exponential penalty, making them essentially useless for model-checking. Recently, Bernholtz and Grumberg [1993] have shown that this exponential penalty can be avoided, though they did not match the linear complexity of non-automata-theoretic algorithms. In this paper, we show that alternating tree automata are the key to a comprehensive automata-theoretic framework for branching temporal logics. Not only can they be used to obtain optimal decision procedures, as was shown by Muller ct al., but, as we show here, they also make it possible to derive optimal model-checking algorithms. Moreover, the simple combinatorial structure that emerges from the automata-theoretic approach opens up new possibilities for the implementation of branching-time model checking, and has enabled us to derive improved space complexity bounds for this long-standing problem.

A traumatic brain injury may have a great impact on the family as a whole and may include changes in the family's organizational structure, communication patterns, or balance of family needs. In spite of this, treatment strategies for these problems are only slowly being recognized, resulting in either family reactions being inadequately addressed in rehabilitative programs, or treatment being approached from a family support perspective and not from a family therapy perspective. The aim of the following paper is to illustrate how family therapeutical approaches can be used in treating families of individuals with brain injury, in particular, structural interventions. Clinical examples will be presented where structural interventions were utilized with brain injury patients and their families. Other inverventional approaches from family therapy will also be mentioned. [less ▲]

Counselling and drug prescription are the only means for the phycisian to manage dental emergencies. Among these, some are infection related: pulpitis, apical and periodontal abscesses, acute necrotizing ulcerative gingivitis and alveolitis. Urgent medical treatment includes antibiotics, mouth rinses and analgesics except for pulpitis (pain caused by thermal stimuli) for which analgesics alone are prescribed. Infection non related dental emergencies are: hemorrhage for which the best treatment is compression; trauma, mainly dental avulsion for which reimplantation must be done as soon as possible; acute TMD such as open lock which can be reduced by the Nelaton handling.

Two immature female fin whales stranded on the Belgian and French coastlines, were examined post mortem. The main gross findings were massive parasitic infestation, associated with a large thrombus in one whale, and severe emaciation. Microscopical investigations revealed multinucleated syncytia with large intranuclear inclusion bodies in various tissues, and positive immunolabelling for morbillivirus antigens. Other evidence of morbillivirus infection was provided by the demonstration of specific viral structures in syncytia and in cell cultures, and the detection of neutralizing antibodies to canine distemper virus. To the authors>> knowledge, this is the first firm report of morbillivirus infection in baleen whales. [less ▲]

Obesity is considered as the most important risk factor for type 2 diabetes. We will briefly discuss why does obesity predispose to diabetes, when does diabetes occur in obese subjects and who among obese individuals is particularly prone to develop diabetes. Obesity, especially intraabdominal adiposity, is associated with increased FFA plasma concentrations which exert a major negative effect on insulin sensitivity at both muscular and hepatic sites. Various metabolic, haemodynamic and hormonal theories have been proposed to explain insulin resistance in obese subjects. A specific role of TNF-alpha has been recently suggested. However, besides insulin resistance, defective insulin secretion is a prerequisie for the development of overt type 2 diabetes. Both lipotoxicity and glucotoxicity may initiate and perpetuate a vicious circle responsible for the metabolic deterioration. Diabetes occurs as a late phenomenon in obesity and is preceded by years of impaired glucose tolerance. The progression to diabetes is heralded by an inability of the B cell to maintain its previously high rate of insulin secretion in response to glucose in face of insulin resistance. This propensity to develop type 2 diabetes may be genetically determined and/or triggered by environmental factors. The evolution from obesity to diabetes represents a continuum that progresses through different phases in which defects in both insulin action and insulin secretion play a critical interaction and must be looked at in concert.

The respective contributions of pituitary and placental GH to circulating IGF-I in pregnant women have not been well established. We measured the serum concentrations of placental growth hormone (PGH) and IGF-I in a woman with pit-1 deficiency before, during and after pregnancy, resulting in the birth of a healthy child (not pit-1 deficient). Both PGH and IGF-I concentrations were below the assay detection limit before and after pregnancy. During pregnancy, PGH and IGF-I levels increased steadily; the concentrations of PGH and IGF-I in late pregnancy were comparable with levels previously measured in normal pregnancies. PGH and IGF-I concentrations were strongly correlated throughout pregnancy (r = 0.90; P = 0.002). PGH was undetectable in cord serum, whilst the IGF-I concentration was within the normal range. The findings of this case study corroborate the notion that PGH is the prime regulator of maternal serum IGF-I during pregnancy. [less ▲]

It is now widely established that systematic intraoperative location and diligent dissection of the recurrent inferior laryngeal nerve during thyroidectomy are the keystones to assure its anatomic and functional preservation. The possibility of abnormal routes, like a non-recurrent cervical course of the inferior laryngeal nerve is an additional major argument for its systematic identification to avoid surgical damage. In 2517 cervicotomies performed between 1992 and 1997 for at least right thyroid lobe excision or parathyroid glands exploration, 20 cases of non recurrent laryngeal nerve were identified (0.79%). The embryological nature of such a nervous anatomical variation results originally from a vascular disorder, named arteria lusoria in which the fourth right aortic arch is abnormally absorbed, being therefore unable to drag the right recurrent laryngeal nerve down when the heart descends and the neck elongates during embryonic development. The surgeon must be aware of the possibility of a non recurrent laryngeal nerve, which arises directly from the cervical vagus and therefore represents a severe potential pitfall during thyroidectomy. Given the absence of reliable clinical symptoms and signs or investigations indicating preoperatively the possibility of a non recurrent nerve, guidelines are given to prevent intraoperatively this major surgical risk.

OBJECTIVE: To assess in vivo blood oxygen binding in double-muscled calves and dairy calves with conventional muscle conformation. ANIMALS: 58 dairy and 48 double-muscled calves. PROCEDURE: Calves were classified as neonatal (24 hours old) or older calves (2 to 26 days old). Venous and arterial blood samples were collected, and hemoglobin concentration, pH, PCO2, and PO2 were determined. Blood oxygen equilibrium curves (OEC) under standard conditions were constructed, and the oxygen exchange fraction (OEF) and the amount of oxygen released at the tissue level by 100 ml of blood (OEF Vol%) were calculated. RESULTS: In each breed, partial pressure of oxygen at 50% saturation of hemoglobin (P50) under standard conditions was significantly higher in older than in neonatal calves, indicating a right shift in OEC with age. Venous P50 was significantly lower in neonatal double-muscled calves than in neonatal dairy calves, but arterial and venous P50 were significantly higher in older double-muscled calves than in older dairy calves. In double-muscled, but not in dairy, calves, OEF was significantly higher in older than in neonatal calves. In neonatal calves, OEF Vol% was not significantly different between breeds, but OEF Vol% was significantly higher in older double-muscled calves than in older dairy calves. CONCLUSIONS AND CLINICAL RELEVANCE: The lower OEF in neonatal double-muscled calves, compared with dairy calves, could contribute to the higher sensitivity of double-muscled calves to hypoxia. Blood oxygen affinity decreased with age, but OEF and OEF Vol% were unchanged with age in dairy calves, whereas they increased with age in double-muscled calves [less ▲]

Retrospective studies have confirmed the feasibility and safety of thyroid and parathyroid procedures performed under hypnoanesthesia (hypnosis, local anesthesia and minimal conscious sedation) as sole method of anesthesia. This very effective technique seems to provide physiological, psychological and economic benefits for the patient. STUDY AIM: To assess, by means of a prospective randomized study, the advantages of hypnosedation as an alternative to general anesthesia in terms of clinical and laboratory parameters. PATIENTS AND METHODS: Twenty patients operated under hypnoanesthesia were compared to 20 patients operated under conventional anesthesia. The two groups were compared in terms of inflammatory, neuroendocrine, hemodynamic and immunologic parameters and postoperative course (pain, fatigue, muscle strength and stress). RESULTS: No clinical or demographic differences were observed between the two groups. Operative times, bleeding, weight of specimens, and surgical comfort were similar. Significant differences in terms of inflammatory response and hemodynamic parameters were observed in favor of hypnoanesthesia. Neuroendocrine and immunological parameters were similar. Patients of the hypnoanesthesia group had significantly less postoperative pain. Postoperative fatigue syndrome and convalescence were significantly improved in these patients. CONCLUSION: This study confirms that, in our hands, hypnosedation presents real advantages over general anesthesia, in patients undergoing thyroid surgery. [less ▲]

The aim of this work was to identify and compare, using nitrogen and carbon stable isotope data, the food sources supporting consumer communities in a Mediterranean seagrass bed (Gulf of Calvi, Corsica) with those in an adjacent epilithic algal dominated community. Isotopic data for consumers are not significantly different in the two communities. Particulate matter and algal material (seagrass epiflora and dominant epilithic macroalgae) appear to be the main food sources in both communities. Generally, the 13C of animals suggests that the seagrass Posidonia oceanica (L.) Delile represents only a minor component of their diet or of the diet of their prey, but the occurrence of a mixed diet is not excluded. P.oceanica dominates the diet of only of few species, among which holothurians appear as key components in the cycling of seagrass material. [less ▲]

Volume tables have been constructed for European larch (Larix decidua Mill.), Japanese larch (Larix kaempferi (Lamb.) Carr.) and hybrid larch (Larix X eurolepis Henry) trees in the Ardenne (southern part of Belgium), which is a natural region located at elevations ranging from 340 to 550 m on mainly siliceous rocks. The application of the proposed tables is only for trees whose diameters (d.b.h.) are less than 22 cm over bark at 1.3 m above ground level. They are particularly useful for estimating total tree volume of trees (excluding branches) of early thinnings and volume increment of small-sized trees in genetic improvement experiments. The volume equations are based on data collected over a wide range of site conditions. In these regional volume tables, the volumes (total volume of the stem and volume to an upper diameter limit of 7 cm) are correlated with both d.b.h. and total height. [less ▲]

Tumor angiogenesis is one of the most important fields of cancer research. It is important to identify the putative targets for antiangiogenic strategies. To date, a number of angiogenic agents have been identified: bFGF, the different VEGF isoforms, integrins, proteases (matrix metalloproteases and serine proteases),... Furthermore, several physiological anti-angiogenic agents have been isolated such as endostatin, angiostatin, 16 K prolactin,.... The recent development of mice deficient for one gene involved during angiogenesis gives a new insight into the molecular mechanisms regulating this process. It leads to the identification of plasminogen activator inhibitor-1 or PAI-1 as a new target for tumor treatment. Although, PAI-1 is very attractive as a target for new therapeutic strategies, a better understanding of its mechanism of action is needed urgently. [less ▲]

Using Cox proportional hazards regression analysis, megaloblastosis (MEGALO), neutrophil agranularity (AGRAN) and hypogranularity (HYPOGRAN) were highly significant predictors (p < 0.005), and Pelger-Huet anomaly (PELGHUET) a significant predictor (p = 0.05), of patient survival. The regression analysis yielded a dysplasia-based risk index (DI) where DI = 1.26 MEGALO + 0.82 AGRAN - 1.08 HYPOGRAN + 0.45 PELGHUET. The two subgroups of 60 and 47 patients with DI < or = 0 and > 0 showed highly significant differences in median survivals (2.6 vs 1.1 yrs; p <0.0001). Multivariate analysis further showed that DI offered additional predictive power that was independent of that provided by the IPSS (p=0.002 and 0.001 respectively). Analysis of survival curves stratified for IPSS and DI showed that the additional predictive power offered by inclusion of the DI essentially concerned the IPSS low/INT-1 risk categories. Further stratification for age did not improve survival prediction. The data indicate that a set of 4 dysplasia parameters can offer some prediction for survival of MDS patients in addition to that provided by the IPSS. Further multicenter studies should aim at including some form of evaluation of the degree of dysplasia in prognostic systems. [less ▲]

We have cloned a novel complementary DNA whose expression was decreased in rat Sertoli cell cultures after treatment with FSH. This complementary DNA encodes a protein of 570 amino acids and shares 92% homology with the human MAGE-D protein. In contrast to other MAGE genes (A, B, or C), we have shown that MAGE-D expression was ubiquitous in healthy rat tissues. In the seminiferous tubules, the MAGE-D was expressed in Sertoli cells but not in germ cells as demonstrated by RT-PCR and in situ hybridization, whereas for the other MAGE genes, expression has been shown to be restricted to germ cells. Interestingly, MAGE-D was also detected for the first time in the female gonad by Northern blotting. In MLTC-1 cells (mouse Leydig tumor cell line-1), LH and PRL stimulated MAGE-D expression. Using hypophysectomized rats, it was confirmed that FSH decreased MAGE-D expression, whereas LH and PRL increased MAGE-D messenger RNA level in the whole testis most probably through a direct action on Leydig cells. As MAGE-D is present in both the seminiferous compartment and interstitium and hormonally regulated in each, it is possible that it has specific functions in each compartment during the development and the maintenance of the testis.

The treatment of dyskalemia must be primarily etiological and later symptomatic. When moderate but significant hypokalemia exists (K < 3 mmol/l or 3.5 mmol/l with cardiac disease), oral K supplements must be given. The intravenous route must be reserved for emergency or impossible oral administration. Acute and severe hyperkalemia (K > 7 mmol/l) must be first corrected by different intravenous measures with secondary oral intervention. In chronic and/or moderate hyperkalemia (K > 5.5 mmol/l), the oral route for treatment is prefered. In any case, the research of the cause (mainly drug induced) is fundamental. [less ▲]

The main requirements for the development of a new grade for the later finishing section of the mill are : good oxidation and thermal behaviour, high wear resistance, good resistance to rolling incidents. The approach of Marichal Ketin to improve the rolling performances in the last finishing stands is presented. The Hi-Cr cast iron possesses excellent wear resistance due to the presence of hard chromium carbides, but its thermal conductivity and sticking properties are fairly low. A graphite precipitation could contribute to an improvement in thermal conductivity and serve as lubricant preventing sticking. The new material, called graphitic chromium iron, shows good oxidation, wear and thermal behaviour allowing its use as work roll in the last stands of the finishing section of a HSM. In the as-cast condition, graphite precipitation in high Ni and Si chromium cast iron occurs at a temperature of 950 degrees C. Moreover, the amount and volume of free graphite may be increased by secondary graphite precipitation during suitable heat treatment. [less ▲]

Arterial blood gases, acid-base balance and respiratory function tests using impulse oscillometry (IOS) were performed on 40 clinically healthy newborn calves during the first 24 hours of life to evaluate their respiratory adaptation to extrauterine life. Gas exchange efficiency of the lung was significantly improved with time and was accompanied by the correction of the mixed acidosis observed at birth and by significant changes in respiratory mechanics. Major changes were detected within the first 6 hours. The significant decrease in resistance (R) and the increase in reactance (X) with time, demonstrate the improvement in respiratory mechanics of both upper and lower airways, and reflect the increase in lung volume, the improved lung tissue elasticity and/or distribution of the ventilation. Respiratory mechanical, arterial blood gases and acid-base balance data provided in this study describe a successful respiratory adaptation to extrauterine life in healthy newborn calves. [less ▲]

Besides genetic predisposition, obesity is the most important risk factor for the development of diabetes mellitus, and weight reduction has been shown to markedly improve blood glucose control in obese subjects with type 2 diabetes. Therapeutic strategies for the obese diabetic patient include: 1) promoting weight loss through lifestyle modifications (hypocaloric diet and exercise) and anti-obesity drugs (orlistat, sibutramine, etc.); 2) improving blood glucose control, essentially through the reduction of insulin resistance (metformin, eventually thiazolidinediones) or insulin need (alpha-glucosidase inhibitors) and, at a later stage, the correction of defective insulin secretion (sulphonylureas, repaglinide) or low circulating insulin levels (exogenous insulin); and 3) treating common associated risk factors, such as arterial hypertension and dyslipidaemias, to improve cardiovascular prognosis. When morbid obesity is present, both restoring a good glycemic control and correcting associated risk factors can only be obtained through marked and sustained weight loss. This primary objective justifies more aggressive weight reduction programmes, including very low-calorie diets and bariatric surgery, but only within a multidisciplinary approach and in well-selected patients.

Vitamin A deficiency produces anemia and altered iron status. In this study with rats we tested two hypotheses regarding vitamin A deficiency: (1) that it impairs erythropoiesis, leading to an increased red cell turnover, and (2) that it inhibits the glycosylation of transferrin. Erythropoietic activity was assessed indirectly by determining the myeloid:erythroid ratio in bone marrow smears, the number of erythroid colonies in the red pulp of spleen, the blood reticulocyte index, and zinc protoporphyrin and plasma transferrin receptor concentrations. Transferrin glycosylation was assessed by measuring the sialic acid content of transferrin. The effects of vitamin A deficiency were compared with those of iron deficiency. Iron deficiency produced anemia and low iron levels in organs. Vitamin A deficiency produced low levels of plasma and hepatic retinol, and it induced decreased plasma total iron-binding capacity and raised iron levels in tibia and spleen. Short- but not long-term iron deficiency reduced the number of erythroid colonies in spleen; vitamin A deficiency had no influence. Neither iron nor vitamin A deficiency influenced the myeloid:erythroid ratio in bone marrow smears and the blood reticulocyte production. Plasma transferrin receptor and erythrocyte zinc protoporphyrin concentrations were not affected by vitamin A deficiency but increased with iron deficiency. Vitamin A deficiency did not stimulate erythrocyte breakdown, as indicated by unaltered plasma lactate dehydrogenase activity and reduced plasma total bilirubin levels. Both vitamin A and iron deficiencies raised the proportion of multiple sialylated transferrins in plasma. Thus, we have not found evidence that vitamin A deficiency affects erythropoiesis and erythrocyte turnover. The iron accumulation in spleen and bone marrow may be related to reduced iron transport due to inhibition of transferrin synthesis rather than inhibition of transferrin sialylation. [less ▲]

MRI guided percutaneous abdominal biopsy was evaluated in an animal model, using a closed magnet and different types of needles. Thirty-six single pass biopsies were performed in 6 piglets with 6 types of MR compatible needles. Virtual targets of a diameter of 2 cm were drawn on the images of the right and left lobe of the liver and the upper and lower poles of both kidneys. FMPSPGR sequences were applied during an apnea of 19 to 23 seconds in axial, sagittal, coronal or axial oblique planes using a closed 1.0 T magnet and the body coil. Piglets were autopsied 1 hour after the procedure. Mean duration of the procedure was 16.9 (11-37) minutes; mean number of acquisitions per procedure was 5.9 (3-12); mean number of redirections of the needle was 0.6 (0-4). Pathological samples from the liver and kidneys of good quality were obtained in 22/36 (72.2%) cases. A subcapsular hematoma was observed in 18/24 (75.0%) cases of renal biopsies and in 1/12 (8.3%) of hepatic biopsies. No statistically significant correlation could be established between duration of the procedure and site of biopsy and between the type of biopsy needle and complication (p = 0.18 to 0.85). In conclusion, MRI guided percutaneous needle biopsy in the abdomen is a reliable technique in piglets using a closed magnet. [less ▲]

Human secreted group IIA phospholipase A2 (hGIIA) was reported to inhibit prothrombinase activity because of binding to factor Xa. This study further shows that hGIIA and its catalytically inactive H48Q mutant prolong the lag time of thrombin generation in human platelet-rich plasma with similar efficiency, indicating that hGIIA exerts an anticoagulant effect independently of phospholipid hydrolysis under ex vivo conditions. Charge reversal of basic residues on the interfacial binding surface (IBS) of hGIIA leads to decreased ability to inhibit prothrombinase activity, which correlates with a reduced affinity for factor Xa, as determined by surface plasmon resonance. Mutation of other surface-exposed basic residues, hydrophobic residues on the IBS, and His48, does not affect the ability of hGIIA to inhibit prothrombinase activity and bind to factor Xa. Other basic, but not neutral or acidic, mammalian secreted phospholipases A2 (sPLA2s) exert a phospholipid-independent inhibitory effect on prothrombinase activity, suggesting that these basic sPLA2s also bind to factor Xa. In conclusion, this study demonstrates that the anticoagulant effect of hGIIA is independent of phospholipid hydrolysis and is based on its interaction with factor Xa, leading to prothrombinase inhibition, even under ex vivo conditions. This study also shows that such an interaction involves basic residues located on the IBS of hGIIA, and suggests that other basic mammalian sPLA2s may also inhibit blood coagulation by a similar mechanism to that described for hGIIA.

Obesity is a well-known risk factor for the development of Type 2 diabetes mellitus. The management of the obese diabetic patient remains a challenge for the clinician but, in any case, weight reduction should be considered as a key objective. In this respect, several antiobesity drugs have demonstrated potential. However, while fenfluramine and dexfenfluramine have been shown to promote weight loss and to directly improve insulin sensitivity, being two mechanisms contributing to better blood glucose control in obese Type 2 diabetic patients, they were recently withdrawn due to safety problems. Sibutramine, a new selective norepinephrine and serotonin reuptake inhibitor, promotes weight loss by decreasing food intake, an effect which leads to a mild improvement (significant in patients losing > or =5% of initial body weight) of blood glucose control in obese diabetic patients. Similarly, orlistat, a selective gastrointestinal lipase inhibitor which increases faecal fat losses, enhances diet-induced weight reduction and improves both blood glucose control and vascular risk profile, especially dyslipidaemia, in obese Type 2 diabetic patients. Further studies are required to better identify good responders to pharmacotherapy and specify the role of antiobesity agents in the overall long-term management of obese subjects with Type 2 diabetes. Other novel pharmacological approaches deserve further consideration, for instance beta-3 agonists aiming to increase energy expenditure, drugs interfering with tumor necrosis factor-alpha (TNF-alpha) or free fatty acid release by the adipose tissue or agents that slow gastric emptying. However, until now, results regarding efficacy and/or safety have been disappointing or preliminary in humans. [less ▲]

Conceiving pedophilic sexuality as a sexuality resulting from a fack of grtifying relationships to adults is an important operational reference for the clinician. In this way, the obstacles to sexual satisfaction with adults can become the privileged target of therapeutic and preventive acts.The narcissic fragility is certainly an obstacle common to almost all the pedophilic patterns. Beyond this common denominator, the individual cases are characterized by strong dissimilarities. The variety of the cases justifies the attempts to classify the different types of pedophiles. But the typological systems are also quite different, depending on the theorical and methodological preferences of their authors. Starting from the ideas of several authors, this article try to sum up the variety of pedophilic functioning in four axes of variation.

The peroxidase and IAA-oxidase activities, the degree of auxin protection and the amount of soluble phenolics were determined in in vitro cultured shoots of a nonrooting mutant, inc, of tobacco compared to its wild homologue. The mutant and wild shoots showed similar peroxidase variations along the growth cycle of 21 days, but with higher levels of activity for the I ac mutant. During this growth cycle, the minimum of peroxidase activity occurred at day 14 for both tobacco whole shoots. However. this minimum of activity did not occur at the same day in the basal part of the stem, where roots may appear, of the two types of tobacco. Both mutant and wild whole shoots showed about the same IAA-oxidase activity in the fractions resulting from a gel filtration of the crude extracts through a sephadex G-100 column but differed in the degree of auxin protection. The rac shoots exhibited a very high level of auxin protectors of low molecular weight, among which chlorogenic acid. They were also characterized by eight to nine times higher level of soluble phenolics. The relationships between these biochemical aspects in relation to the absence of root formation in the me mutant are discussed. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved. [less ▲]

Therefore the specific heat can be deduced. The role of a radiation shield is shown to be relevant. Tests of the system are made on a 99.9% pure Cu sample and two polycrystalline cuprate ceramics for illustration. Without any complicated optimisation, the technique indicates much promise already due to its efficiency and rapidity. [less ▲]

BACKGROUND: Donor lymphocyte infusion (DLI) is currently standard therapy for relapse of malignancies after allogeneic BMT. Several observations suggest that both normal and leukemic progenitor cells of host origin constitute effective target cells for donor-derived lymphocytes. To prevent relapse of sickle cell disease (SCD), a child with evidence of decreasing mixed chimerism received DLIs 8 months after allogeneic BMT for SCD. CASE REPORT: A 4-year-old child who was homozygous for SCD underwent a transplantation of bone marrow from his fully HLA-matched sister. Routine detection of sex chromosomes in bone marrow cells evidenced decreasing mixed chimerism, which heralded a probably imminent recurrence of the disease. The patient received two DLIs in graded incremental doses on Days 234 and 267. One month later, he developed grade 2 acute GVHD that responded well to corticosteroids and cyclosporine. RESULTS: DLI resulted in complete donor chimerism within 2 months of the second infusion. Now, 2 years after the second DLI, the patient is in excellent condition, with normal Hb and excellent growth and development. CONCLUSION: This is the first report of successful use of DLI in a patient with probable imminent SCD recurrence after allogeneic BMT. It shows that DLI can displace residual host HPCs in case of recurrence of nonmalignant disease after allogeneic BMT. [less ▲]

Humans, like numerous other species, strongly rely on the observation of gestures of other individuals in their everyday life. It is hypothesized that the visual processing of human gestures is sustained by a specific functional architecture, even at an early prelexical cognitive stage, different from that required for the processing of other visual entities. In the present PET study, the neural basis of visual gesture analysis was investigated with functional neuroimaging of brain activity during naming and orientation tasks performed on pictures of either static gestures (upper-limb postures) or tridimensional objects. To prevent automatic object-related cerebral activation during the visual processing of postures, only intransitive postures were selected, i.e., symbolic or meaningless postures which do not imply the handling of objects. Conversely, only intransitive objects which cannot be handled were selected to prevent gesture-related activation during their visual processing. Results clearly demonstrate a significant functional segregation between the processing of static intransitive postures and the processing of intransitive tridimensional objects. Visual processing of objects elicited mainly occipital and fusiform gyrus activity, while visual processing of postures strongly activated the lateral occipitotemporal junction, encroaching upon area MT/V5, involved in motion analysis. These findings suggest that the lateral occipitotemporal junction, working in association with area MT/V5, plays a prominent role in the high-level perceptual analysis of gesture, namely the construction of its visual representation, available for subsequent recognition or imitation.

OBJECTIVE: To isolate new cDNAs corresponding to genes whose expression is increased during castration-induced rat prostate apoptosis. MATERIALS AND METHODS: Differential display of mRNAs from 3-day castrated and normal rat ventral prostates was used to identify differentially expressed clones. Northern blots were hybridized to confirm the positive regulation of the candidates and to follow the change in their expression in the involuting rat prostate, and in thymocytes of dexamethazone-treated rats. RESULTS: Five cDNAs were cloned: one encoding ribosomal protein L7, one coding for the insulin-like growth factor binding protein-3 (IGFBP-3), and three whose products are unknown. After castration, all five genes had expression kinetics that closely paralleled the proportion of prostatic epithelial cells undergoing apoptosis. The gene encoding L7 and two of the unknown genes were also upregulated in glucocorticoid-induced programmed death in thymocytes. In addition to the IGFBP-3 gene, those coding for proteins IGFBP-4, -5 and -6 were also overexpressed in the involuting prostate of androgen-deprived rats. CONCLUSION: Five new genes were identified that are up-regulated during castration-induced rat prostate apoptosis, three of which are potentially involved in the common intracellular pathway leading to programmed cell death.

The spectroscopic properties of photoactive (ie. flash-transformable) and nonphotoactive protochlorophyll(ide)s (Pchl(ide)) were reinvestigated during the development of bean leaves in darkness. Two phases in the process of Pchl(ide) accumulation were apparent from quantitative measurements of pigment content: a lag phase (first week) during which photoactive Pchl(ide) accumulated faster than nonphotoactive Pchl(ide); and a fast phase (second week), showing parallel accumulation of both types of Pchl(ide). 'Flashed-minus-dark' absorbance difference spectra recorded in situ at 77 K showed that P650-655 was the predominant form of photoactive protochlorophyllide regardless of developmental stage. Quantitative analysis of energy migration processes between the Pchl(ide) forms showed the existence of energy transfer units containing a 1:8 ratio of nonphotoactive and photoactive Pchl(ide)s during development. Gaussian deconvolution of in situ 77 K fluorescence spectra indicated that the 633 nm band of nonphotoactive Pchl(ide) was made of four bands, at 625, 631, 637 and 643 nm, whose relative amplitudes only slightly changed during development. The emission band of photoactive Pchlide was also analyzed using the same method. Three components were found at 644, 652 and 657 nm, The emission band of P650-655 included the last two components, which become predominant only in fully etiolated plants. Photoactive Pchlide with an emission maximum at 653 nm was detected in the light during development of leaves of photoperiodically grown plants. [less ▲]

The electrochemical control of the binding of metallic ions (actinides and a lanthanide) by redox active polyaniline resin, i.e., polyaniline doped by polystyrene sulfonate (Pani/PSSO3), has been studied. Electrochemical and nuclear techniques (cyclic voltammetry, α -counting, Rutherford backscattering) have been used in order to characterize the exchange of thorium, lanthanum and uranium cations, particularly in terms of reversibility and efficiency. This electrochemical process has been compared with the chemical one promoted merely by pH variation, and the efficiency of the two methods has been discussed for each type of cation. [less ▲]
