Homeodomain-containing proteins are transcription factors that regulate the co-ordinated expression of multiple genes involved in development, differentiation and malignant transformation. In an attempt to characterize expressed homeobox (HOX) genes in breast cancer cells, we cloned two distinct HOXC6 transcripts from an MCF7 cDNA library, Interestingly, one of them represents a new HOXC6 mRNA encoding a homeodomain-containing protein harbouring a unique N-terminal sequence. Moreover we demonstrate that this HOXC6 transcript is less abundant in human breast cancer cells than in non-tumorigenic cell lines, is detected in breast carcinomas and adjacent tissues and is expressed in a variety of human tumours. In addition, transient co-transfection experiments illustrated that both HOXC6 transcripts encode gene products that repress transcription from a HOX binding sequence in MDA-MB231 cells and co-operate with other HOX gene products such as HOXB7 on their target genes. Taken together, our results suggest that HOXC6 proteins might contribute to the breast cell phenotype through co-operative interactions with other HOX-derived proteins and repression of their target genes.

An inheritable muscular hypertrophy was recently described in sheep and shown to be determined by the callipyge gene mapped to ovine chromosome 18. Here, the callipyge phenotype was found to be characterized by a nonmendelian inheritance pattern, referred to as polar overdominance, where only heterozygous individuals having inherited the callipyge mutation from their sire express the phenotype. The possible role of parental imprinting in the determinism of polar overdominance is envisaged. [less ▲]

OBJECTIVES: To compare histologically and stereologically the endometriotic nodule of the rectovaginal septum to peritoneal endometriosis. DESIGN: Morphometric investigation, cytokeratin and vimentin content, and steroid receptor evaluation were performed on endometriotic tissue from the peritoneum (n = 52) and rectovaginal nodules (n = 68). SETTING: An academic teaching hospital. PATIENTS: Biopsies were taken from 120 patients undergoing a laparoscopy for infertility and/ or pelvic pain (52 from typical black peritoneal endometriotic implants and 68 from endometriotic nodule of the rectovaginal septum). None of the patients were treated. RESULTS: Mitotic activity was found to be significantly different in peritoneal and rectovaginal endometriosis. The evaluation suggested that the stroma is not mandatory for the invasion of glandular epithelium in the rectovaginal nodule, which is, like a adenomyoma, a circumscribed nodular aggregate of smooth muscle and glandular elements. Cytokeratin and vimentin content as well as the estrogen receptor (ER) and P receptor (PR) content were significantly lower in both types of lesion when compared with eutopic endometrium. But vimentin immunoreactivity in epithelium, as well as the ER and PR content, were significantly lower in nodules when compared with black peritoneal lesions. CONCLUSION: It is suggested that the rectovaginal endometriotic nodule is a different disease from peritoneal endometriosis and must be called rectovaginal adenomyosis or rectovaginal adenomyoma. Its histopathogenesis probably is not related to the implantation of regurgitated endometrial cells but to the metaplasia of Müllerian rests. [less ▲]

Le présent article met en évidence les pertinences de l'idée d'un recours à la pensée philosophique pour mieux asseoir une approche socio-anthropologique du sens ordinaire de la justice. Pour se faire, l'auteur se propose d'analyser les présupposés épistémologiques et théoriques des trois courants philosophiques anglo-saxons qui placent au centre de leurs réflexions la question de la justice. Il montre, ce faisant, les limites de la thèse "libérale" et les apports respectifs des thèses marxienne et communautarienne. Certaines positions théoriques d'auteurs dits communautariens se révèlent plus pertinentes dans la mesure où elles permettent de situer la question de la justice à l'intérieur d'une tradition et de lui conférer un contenu socio-historique. Elles débouchent, de ce fait, sur une conception pluraliste de la justice qui permet de prendre en compte les données empiriques propres à une société de tradition arabo-islamique. [less ▲]

A cold-active alpha-amylase was purified from culture supernatants of the antarctic psychrophile Alteromonas haloplanctis A23 grown at 4 degrees C. In order to contribute to the understanding of the molecular basis of cold adaptations, crystallographic studies of this cold-adapted enzyme have been initiated because a three-dimensional structure of a mesophilic counterpart, pig pancreatic alpha-amylase, already exists. alpha-Amylase from A. haloplanctis, which shares 53% sequence identity with pig pancreatic alpha-amylase, has been crystallized and data to 1.85 A have been collected. The space group is found to be C222(1) with a = 71.40 A, b = 138.88 A, and c = 115.66 A. Until now, a three-dimensional structure of a psychrophilic enzyme is lacking. [less ▲]

Multifrequency impulse oscillometry (IOS) was compared with a monofrequency forced oscillation technique (MFO) in calves undergoing experimentally induced bronchoconstriction and subsequent bronchodilatation. The dynamic lung compliance (Cdyn) was also measured by conventional methods. For each test, the baseline mean and the responses to saline, a bronchoconstrictive agent (carbachol) and a bronchodilator (fenoterolhydrobromide) were calculated. Using the IOS, the information was markedly frequency-dependent. The resistance (R) and the magnitude of respiratory impedance (Z) were only sensitive at 5 Hz, leading to negative frequency dependence of these parameters as an indicator of peripheral airway obstruction. A high sensitivity for reactance (X) and phase angle phi values was observed between 5 and 20 Hz. For MFO (10 Hz), the parameters Ros (which includes resistive and capacitive components of the respiratory system), phase shift (psi), and the oscillatory derived compliance of the respiratory system (Crs) were of the greatest clinical potential. Crs showed a significant coefficient of linear correlation (r = 0.88, P < 0.001) with Cdyn. At the 10 Hz test frequency similar results were observed with MFO and IOS, suggesting that for healthy calves the measurement effect of an impulse is not significant. With respect to peripheral airway calibre, a test frequency less than 10 Hz appeared to be most sensitive and least variable. [less ▲]

We examined the influence of vessel size using an intention-to-treat approach in 259 patients who underwent stent implantation and in 257 patients who underwent balloon angioplasty alone in the BENESTENT trial. In the stented population, smaller vessel size was associated with a higher stent:vessel ratio, a greater relative gain and a greater subsequent loss index, and a higher risk of adverse cardiac events. In the balloon angioplasty population small vessel size conveyed an increased requirement for revascularization but did not increase the risk of procedural failure or myocardial infarction during follow-up. Logistic regression indicated that decreasing vessel size (as a continous variable) was associated with an increasing risk of a cardiac event for both the stent and balloon angioplasty populations.

Objective: To verify the influence of age on the prognosis of cervix carcinoma. Study design: Five hundred and sixty eight patients treated for a FIGO stage IB-IVA with radical irradiation in the Centre Hospitalier Universitaire Vaudois of Lausanne were subdivided according to the following age categories: _<45, 46-60, 61-69 and > 70 years. Taking the 46-60 years age group as the reference, the hazard ratios (HR) of death and corresponding 95% confidence intervals (95% CI) were estimated by means of a Cox multivariate analysis. Results: The 5-year survival rates were, respectively, 57%, 67%, 60% and 45%. For the youngest women the risk of death was significantly increased (HR = 2.00, 95% CI [1.32-3.00]) and was even more accentuated in advanced stages. Conclusion: Age under 45 years is a bad prognostic factor in carcinoma of the cervix. [less ▲]

During the last four years, an increasing number of cattle herds were classified positive by brucellosis screening tests in areas of Belgium and France free of the disease. No clinical symptom of brucellosis was reported in these animals and no Brucella abortus strains were isolated. After two years, no brucellosis outbreak was registered in all of the herds concerned. On this basis, all the serological reactions observed were classified as false positive. An ELISA using Yersinia Outer membrane Proteins (YOPs) as antigens was developed in order to discriminate between a Yersinia enterocolitica O:9 infection and a Brucella abortus infection. Antibodies against YOPs were detected in sera from Y. enterocolitica O:9 experimentally infected cattle (n = 4) but not in sera from B. abortus experimentally infected cattle (n = 4). In a field study, 66.7% of the 174 serum samples from cattle presenting false positive serological reactions showed anti-YOPs antibodies whereas only 10% of 454 sera, classified negative by the brucellosis screening tests, showed anti-YOPs antibodies. Our results suggest that infections with Y. enterocolitica O:9 may cause false positive reactions in brucellosis testing. [less ▲]

See detailRecently advanced computerized technology was applied to the investigation of morphometric, immunohistological and three-dimensional changes of the endometrial mucosa in order to evaluate quantitatively the effects of three doses of a new slow-release vaginal progesterone on the endometrium in post-menopausal women. A total of 20 menopausal women, deprived of ovarian function, were given oestrogen for 12 days and a combined therapy of oestrogen (administered orally) and progesterone for another 12 day period. Progesterone was administered vaginally through a new gel (Crinone) utilizing a bioadhesive, biocompatible polymer as a base to achieve a sustained release effect. An endometrial biopsy was taken before treatment, after oestrogen-only treatment and after the oestro-progestogen therapy. Before treatment, all the patients exhibited an atrophic endometrium. After oestrogen-only treatment, typical proliferative changes occurred: an increase in the endometrium thickness, an increase in the mitotic index, numerous cylinder-like glands and no coiled glands, and high concentrations of oestrogen receptors (ER) and progesterone receptors (PR). After the oestro-progestogen therapy, whatever the dose of progesterone given, a secretory transformation of the endometrial mucosa occurred, mitotic activity decreased significantly, more ramified and coiled glands were observed, and a decrease in PR content was noted in epithelial and stromal nuclei, and a decrease in PR content was also observed in epithelial nuclei but not in stromal nuclei. Accurate new techniques of image analysis have shown that crinone therapy could eliminate the proliferative effects of oestrogen treatment in post-menopausal women, despite doses as low as 45 mg of progesterone administered vaginally every other day. The results suggest that the sustained release effects of Crinone are clinically relevant.

A computerized morphometrical investigation was performed on endometriotic tissue from the peritoneum (n = 225) and rectovaginal nodules (n = 65) to compare histologically and stereologically the rectovaginal septum endometriotic nodule to peritoneal endometriosis. Mitotic activity, stromal vascularization and the epithelium/stroma ratio were found to be significantly different in peritoneal and rectovaginal endometriosis. The evaluation revealed a major role of glandular epithelium in rectovaginal nodules where the stroma sometimes appeared absent around glandular epithelium. The study demonstrated opposite effects of gonadotrophin-releasing hormone agonists (GnRHa) and lynestrenol on the two lesions. Indeed, in peritoneal endometriosis, after GnRHa therapy, our study demonstrated a lower rate of mitosis and poor stromal vascularization. The same drug was unable to induce the same effects in the nodule although, in contrast, lynestrenol has a strong effect on nodule vascularization. In conclusion, it is suggested that the rectovaginal adenomyotic nodule is a specific disease, different from peritoneal endometriosis. It is not the consequence of 'deep infiltrating' endometriosis but can probably develop from Mullerian rests present in the rectovaginal septum. [less ▲]

BACKGROUND: The purpose of the Benestent-II Pilot Study was to evaluate the safety of delaying and eliminating anticoagulant therapy in patients receiving a heparin-coated stent in conjunction with antiplatelet drugs. METHODS AND RESULTS: The study consisted of three initial phases (I, II, III) during which resumption of heparin therapy after sheath removal was progressively deferred by 6, 12, and 36 hours. In phase IV, coumadin and heparin were replaced by 250 mg ticlopidine and 100 mg aspirin. Of the 207 patients with stable angina pectoris and a de novo lesion in whom heparin-coated stent implantation was attempted, implantation was successful in 202 patients (98%). Stent thrombosis did not occur during all four phases, and the overall clinical success rate at discharge was 99%. Bleeding complications requiring blood transfusion or surgery fell from 7.9% in phase I to 5.9%, 4%, and 0% in the three following phases. Hospital stay was 7.4, 6.1, 7.2, and 3.1 days for the consecutive phases. The restenosis rate for the combined four phases was 13% (15% in phase I, 20% in phase II, 11% in phase III, and 6% in phase IV). The overall rate of reintervention for the four phases was 8.9%. At 6 months, 84%, 75%, 94%, and 92% of the patients of phases I to IV, respectively, were event free. For the four phases, the event-free rate was 86%, which compares favorably with the rate observed in the Benestent-I study (80%; relative risk, 0.68 [0.45 to 1.04]). CONCLUSIONS: The implantation of stents coated with polyamine and end-point-attached heparin in stable patients with one significant de novo coronary lesion is well tolerated, is associated with no (sub)acute stent thrombosis, and results in a favorable event-free survival after 6 months.

Through a wide review of the litterature (330 references), the authors have tried to describe the determinant or predisposing effects of factors usually involved in the reproduction problems in beef or dairy cattle. These factors have been qualified as individual or herd factors. The first ones involve the animal itself like age, genetic, milk production level, dystocia, twinning, perinatal mortality, placental retentio, milk fever, uterine involution, metritis, post-partum ovarian activity. The second ones concern the environnement of the animal i.e. first insemination policy, oestrus detection, insemination time and technic, nutrition, season, stabulation, herd size or management capacity of the farmer. The authors conclude to the multifactorial etiology of the reproduction pathologies. It also appears necessary to develop data collection systems like herd health management programs. Such systems should be able to offer to the practitionner the opportunity to be involved more efficiently in the economic health of the herd using epidemiological tools to study the different implied factors.

Most of the mutations causing deficiency of the pyruvate dehydrogenase (PDH) complex are in the X-linked E1 alpha gene. We have developed a rapid screening method for the detection of mutations in this gene using reverse transcription of total RNA, polymerase chain reaction amplification of the whole coding region of the gene and single-strand conformation polymorphism (SSCP) analysis. With this method, we studied eight patients with a PDH complex deficiency, using cultured fibroblasts. In all patients, aberrant SSCP patterns were found and, after sequencing of the corresponding fragments, we were able to identify six new mutations and two mutations already described previously. The mutations are point mutations leading to amino acid substitutions (5) and direct repeat insertions (3). The presence of the mutations was confirmed in genomic fibroblast DNA. The 4 female patients were shown to carry both a normal and a mutated E1 alpha gene. [less ▲]

The design of reinforced concrete columns under fire conditions is generally made on the basis of national and international recommendations. The CEB/FIP recommendations have been used for many years. Recently, in the framework of the Eurocodes, the document ENV 1992-1-2 (Eurocode 2-1-2), Structural fire design, has been approved by Commission CEN/TC250/SC2 of the European Committee for Standardization. In the CEB/FIP documents and in Eurocode 2-1-2 the main part is devoted to design from tabulated data containing the dimensions of the cross-sections and values for the concrete cover. The use of simplified calculation methods is not current practice for concrete elements, while they are widely used in the case of steel. The determination of the temperature distribution in the cross-section does not facilitate the development of a simplified method. Furthermore, in columns there is a wide scatter of experimental results. In order to gain additional information, an extensive experimental research programme on the behaviour of reinforced concrete columns under fire conditions, financially supported by the Belgian Funds for Fundamental Collective Research (FRFC-FKFO), has been performed at the Universities of Liege and Ghent. In this article the results of this research are presented and the influence of the main parameters is analysed. [less ▲]

As the protein sequence and structure databases expand, the relationships between proteins, the notion of protein superfamily, and the driving forces of evolution are better understood. Key steps of the synthesis of the bacterial cell wall peptidoglycan are revisited in light of these advances. The reactions through which the D-alanyl-D-alanine depeptide is formed, utilized, and hydrolyzed and the sites of action of the glycopeptide and beta-lactam antibiotics illustrate the concept according to which new enzyme functions evolve as a result of tinkering of existing proteins. This occurs by the acquisition of local structural changes, the fusion into multimodular polypeptides, and the association into multiprotein complexes. [less ▲]

The Ardennais draught horse (DH) is more and more used for harnessing competitions. The aim of this study was to improve our knowledge of its cardiorespiratory peculiarities, both at rest and during exercise. At rest, arterial blood gas analysis, venous blood analysis, a test of mechanics of breathing and an endoscopy of the upper airways were performed. Experiments during exercise were performed on a treadmill. The intensity of the standardised test was sufficient to overshoot the OBLA threshold. The test was of increasing intensity and lasted 22 min. The cardiorespiratory parameters were measured during the last 5 min. Expired volume minute (VE), VT and f were measured. Respiratory O2 and CO2 fraction were measured with a mass spectrometer. Oxygen uptake (VOA, CO2 output (VCO2) and VE/VO2 were calculated. Heart rate (HR) was continuously measured.The results were compared to data recorded in standarbred horses (SH) during a treadmill exercise test leading to a similar lactaci¬demia (LA) and peak HR.The DH have a significantly lower V02 than the SH while running at an exercise intensity inducing the same HR and LA modifications. The lower aerobic capacity of DH was at least partly correlated with their higher cost of breathing and lower blood gas transport capacity.Moreover, other measurements have been performed infield conditions, during 4 draft competitions, i.e. speed, maniability, power and endurance. Venous blood analyses before and after the competition, heart rate and body temperature measurements were performed. The results of this second set of measurements confirm the results obtained in the laboratory and allow assessing that these kinds of competition do not induce dramatic physiological modifications and therefore respect the welfare and limits of these horses.

The study of several caves in siliceous formations belonging to the Precambrian basement and its Cenozoic sedimentary cover brings to the fore the importante of an underground drainage network in relation with crustal fracturation. This network guides the waler transfer from the land surface to the depth and generates géomorphologic phenomena similar to those in calcareous areas. The study of caves in a siliceous environmemts shows the importance of solution phenomena in their formation and also in that of West Niger landscapes. Therfore, a general model of topographic evolution îs proposed. [less ▲]

A new experimental setup was developed to expose pigs to dust and airborne endotoxins in an environmental chamber, at levels liable to be encountered in pig farm buildings. The following parameters were evaluated in a chamber containing two pigs of 10 kg body-weight: inhalable and respirable dust gravimetric concentrations were measured using area samplers and expressed as mg/m3. The respirable dust concentration was also measured using a "TM digital microP respirable dust-measuring instrument', which has been shown to give similar results to the gravimetric method. The endotoxin concentration was evaluated using the Limulus-assay and expressed as ng/m3 of air containing the inhalable or respirable dust or as ng/mg of inhalable and respirable dust. Feed flour dust was introduced into the chamber to obtain different concentrations of inhalable and respirable dust ranging from 3.62 to 76.66 mg/m3 and from 0.24 to 1.40 mg/m3, respectively. The endotoxin concentration was modulated by mixing the feed flour with Escherichia coli endotoxins before blowing it into the chamber. The endotoxin concentrations in the air containing inhalable or respirable dust ranged from 28.9 to 270.0 ng/m3 and from 2.22 to 36.38 ng/m3, respectively, depending on the amount of endotoxins added to the dust. Data were also obtained in a piggery. The experimental setup detailed in this paper could be used to study the significance of air contaminants in the development of pig respiratory diseases.

Twelve animals affected with syndactyly or mulefoot were sampled in the Dutch black-and-white cattle population. Analysis of the pedigree data reveal that all of these individuals traced back to a single acknowledged carrier founder individual. Between seven and nine generations separated the founder from its 12 affected descendents. The 12 affected offspring were genotyped for a battery of 213 microsatellites spanning the 29 bovine autosomes. The resulting genotypes were analyzed using a maximum likelihood approach searching for shared homozygous haplotypes among affected individuals. Three candidate regions for the syndactyly locus emerged from this initial screening. syndactyly was shown to map to one of these candidate regions on chromosome 15 by genotyping 29 additional individuals linking founder and affected offspring and performing a conventional linkage analysis with the LINKAGE programs. This study illustrates the potential of identity-by-descent mapping in livestock populations. [less ▲]

A gene of Pseudomonas alginovora, called aly, has been cloned in Escherichia coli using a battery of PCR techniques and sequenced. It encodes a 210-amino-acid alginate lyase (EC 4.2.2.3), Aly, in the form of a 233-amino-acid precursor. P. alginovora Aly has been overproduced in E. coli with a His-tag sequence fused at the C-terminal end under conditions in which the formation of inclusion bodies is avoided. His-tagged P. alginovora Aly has the same enzymic properties as the wild-type enzyme and has the specificity of a mannuronate lyase. It can be purified in a one-step procedure by affinity chromatography on Ni(2+)-nitriloacetate resin. The yield is of 5 mg of enzyme per litre of culture. The amplification factor is 12.5 compared with the level of production by wild-type P. alginovora. The six alginate lyases of known primary structure fall into three distinct classes, one of which comprises the pair P. alginovora Aly and Klebsiella pneumoniae Aly. [less ▲]

Western analysis and immunohistochemistry were used to determine the time-course and the distribution of the 27,000 mol. wt heat shock protein, Hsp27, in rat brain following systemic administration of kainic acid. No Hsp27 immunoreactivity was detected in naive control animals or in rats that failed to develop status epilepticus. Hsp27 immunoreactivity was detected as early as 12 h in the parietal cortex, piriform cortex and the hippocampus of rats that developed status epilepticus. The number of cells expressing Hsp27 and the intensity of Hsp27 immunoreactivity were increased 24 h after kainic acid administration. Hsp27 immunoreactivity was still observed seven days post-kainic acid injection. The morphology of the Hsp27-positive cells and double immunofluorescence against Hsp27 and glial fibrillary acidic protein revealed that Hsp27-positive cells were astrocytes. In addition, the distribution of Hsp27 suggested that astrocytic Hsp27 was dependent on excitation-induced metabolic stress rather than the direct effect of kainic acid on astrocytes. [less ▲]

Thiamine diphosphate (TDP) is an important cofactor of pyruvate (PDH) and alpha-ketoglutarate (KGDH) dehydrogenases and transketolase. Thiamine deficiency leads to reversible and irreversible brain lesions due to impaired oxidative metabolism. A specific non-cofactor role for thiamine has also been proposed in excitable cells and thiamine triphosphate (TTP) might be involved in the regulation of ion channels. Thiamine is taken up by neuroblastoma cells through a high affinity transporter. Inside the cells, it is rapidly phosphorylated to TDP. This high turnover TDP pool is the precursor for TTP. Most of the TDP however has a low turnover and is associated with PDH and KGDH in mitochondria. In excised inside-out patches from neuroblastoma cells, TTP, at a concentration of 1 microM, activates chloride channels of large unitary conductance, the so-called maxi-Cl- channels. These channels are inhibited by oxythiamine from the outide. In addition to the role of TTP in the regulation of chloride channels, thiamine itself, or a presently unknown analog, may have trophic effects on neuronal cells. [less ▲]

Cytokines are potent regulators of the chondrocyte functions. Some of them are produced by chondrocytes and interact to regulate cartilage metabolism. In this study, we investigated the production of interleukin-1 beta (IL-1 beta), IL-6, IL-8 and leukemia inhibitory factor (LIF) by human chondrocytes and examined the modulation of their secretion by exogenous cytokines. Human articular chondrocytes were isolated from their extracellular matrix by a triple successive enzymatic digestion of the cartilage. Subsequently, chondrocytes were stimulated by increased amounts of human recombinant cytokines [IL-1 beta, tumour necrosis factor alpha (TNF alpha), IL-8, LIF, IL-6]. IL-1 beta, IL-6, IL-8 and LIF were assayed into culture media and inside cell extracts by specific enzyme amplified sensitivity immunoassays (EASIAs). Under these experimental conditions, we have identified various interactions between cytokines. IL-beta and TNF alpha highly stimulated IL-6, LIF and IL-8 productions. IL-6 decreased IL-8 synthesis and increased LIF production. IL-8 slightly enhanced IL-6 production. Finally, LIF stimulated IL-1 beta, IL-6 and IL-8 productions. Using neutralizing antibodies against IL-1, we demonstrated that the effects of LIF were secondary to the stimulation by LIF of IL-1 beta production by the chondrocytes. In conclusion, chondrocytes secrete a variety of immunocompetent cytokines including IL-1 beta, IL-6, IL-8 and LIF that can interact to regulate chondrocytes metabolism. These results also define new biological activities of LIF and IL-6, and raise questions concerning their role in the pathogenesis of joint diseases. [less ▲]

In order to determine the nearly complete 16S rRNA gene sequences of cyanobacteria originating from nonaxenic cultures, a cyanobacterium-specific oligonucleotide probe was developed to distinguish polymerase chain reaction (PCR) products of the cyanobacterial rRNA operons from those resulting from amplification of contaminating bacteria. Using this screening method the 16S rRNA genes of four nonaxenic filamentous cyanobacterial strains belonging to the genera Leptolyngbya and OscitIatoria were cloned and sequenced. For the genus Leptolyngbya, the 16S rRNA sequence of the axenic strain PCC 73110 was also determined. Phylogenetic trees were constructed based on complete and partial sequences. The results show that the strains Leptolyngbya Jbveolarum Kom~rek 1964/112, Leptolyngbya sp. VRUC 135 Albertano t985/1, and LeptoIyngbya boryanum PCC 73110 belong to the same cluster. Strain Oscillatoria cf. corallinae SAG 8.92, which contains the rare photosynthetic pigment CUphycoerythrin, is not closely related to other CUphycoerythrin- containing cyanobacteria. Oscillatoria agardhii CYA 18, which is a representative of planktonic Oscillatoria species that form toxic blooms in Norwegian inland waters, has no close relatives in the tree. [less ▲]

Fifty-four dogs with nasal tumours were included in this study. Based on histopathology 52 tumours were malignant (36 epithelial and 16 mesenchymal) and two were benign (one oncocytoma and one pleiomorphic adenoma). Malignancy was significantly more frequently diagnosed by imprint cytology (81 per cent of the cases) than by brush cytology (56 per cent). Brush cytology was a significantly more sensitive technique in epithelial than in mesenchymal tumours, while the sensitivity of imprint cytology was not affected by the histological type. Brush cytology determined an epithelial origin in 88 per cent of epithelial tumours, and imprint cytology in 90 per cent. In mesenchymal tumours, the scores were significantly lower, the histological type being determined in only 20 per cent and 50 per cent, using brush and imprint cytology, respectively. [less ▲]

BACKGROUND: High levels of neuron specific enolase (NSE) have recently been described in the bronchoalveolar lavage (BAL) fluid of patients with lung carcinoma. Although its value in serum has been extensively studied, its diagnostic value in BAL fluid in terms of sensitivity, specificity, and predictive value have not been evaluated. In addition, its value in staging and relation to serum NSE are yet unknown. METHODS: NSE levels were determined on the same day in the BAL fluid and the sera of two groups of patients: those with newly diagnosed lung carcinoma and those with smoking related chronic obstructive pulmonary disease (COPD). Clinical TNM staging was also performed. Levels of NSE in BAL fluid were expressed as nanograms per 100 international units of lactate dehydrogenase. BAL fluid NSE levels of the two groups were compared with staging and serum NSE. RESULTS: A highly significant difference exists in BAL NSE in the two groups. For diagnostic purposes, the simultaneous measurements of serum NSE increases its sensitivity, but specificity remains unchanged. No correlation exists between BAL NSE and serum NSE, tumor size, nodal status, or the presence of metastases. BAL NSE is a better predictor of malignancy than serum NSE. CONCLUSION: BAL fluid measurements of NSE may have diagnostic value, specially if it is simultaneously measured in the serum. However, our study does not show any value for this technique in staging of lung carcinoma. Also it has no correlation with serum NSE. Studies will have to be performed to determine if BAL NSE can predict chemotherapeutic sensitivity. [less ▲]

Medical informatics is defined as the scientific discipline concerned with the systematic processing of data, information and knowledge in medicine and health care. The domain of medical informatics (including health informatics), its aim, methods and tools, and its relevance to other disciplines in medicine and health sciences are outlined. It is recognized that one of the major tasks of medical informatics is modelling processes. In this context, biological, communication, decision, engineering, educational, organizational and computational processes are distinguished and described. [less ▲]

The trisaccharide Gal alpha 1-->3Gal beta 1-->4GlcNAc beta 1-->O-(CH2)8COOCH3 was enzymatically synthesized, with in situ UDP-Gal regeneration. By combination in one pot of only four enzymes, namely, sucrose synthase, UDP-Glc 4'-epimerase, UDP-Gal:GlcNAc beta 4-galactosyltransferase and UDP-Gal:Gal beta 1-->4GlcNAc alpha 3-galactosyltransferase, Gal alpha 1-->3Gal beta 1-->4GlcNAc beta 1-->O-(CH2)8COOCH3 was formed in a 2.2 mumol ml-1 yield starting from the acceptor GlcNAc beta 1-->O-(CH2)8COOCH3. This is an efficient and convenient method for the synthesis of the Gal alpha 1-->3Gal beta 1-->4GlcNAc epitope which pays an important role in various biological and immunological processes.

Androgenetic alopecia (AGA) is a common yet poorly understood condition. In particular, the significance of inflammatory cells close to the infrainfundibulum of transitional hairs remains obscure. This study was conducted in 20 men who used a lotion containing the antimicrobials, piroctone olamine and triclosan, regularly for 18 months. At entry, mild pruritus and abnormal hair loss were reported by the volunteers. During treatments, pruritus resolved rapidly. Comparison of clinical photographs and trichograms taken at 3-month intervals suggested signs of hair regrowth with moderate increase in density of transitional hairs. Biopsies taken at 6-month intervals were processed for immunohistochemistry. There was a decrease in the density of activated T cells in the region of the follicular infrainfundibulum and isthmus over time. UgG deposits found within the epithelial sheaths at entry to the study were absent in the subsequent biopsies. The volume of the sebaceous glands, as assessed by computerized morphometry, was not modified by the treatment. It was concluded that inflammation associated with AGA transitional hairs may be driven by the presence of microorganisms harboured in the infrainfundibulum. They may modulate the severity of AGA and may potentially be controllable. This offers a new possibility of prevention and partial reversal of hair loss in AGA. [less ▲]
