Abstract
Introduction Les études descriptives initiales sur la COVID-19 se sont concentrées sur les formes graves des personnes hospitalisées. Les données sont plus rares concernant les formes ambulatoires, ainsi que leur évolution à long terme. Nous décrivons ici les symptômes et leur persistance dans une cohorte de patients ambulatoires COVID-19. Matériels et méthodes Notre hôpital universitaire a utilisé un logiciel de télémédecine (MH LINK) comme moyen de surveillance des patients ambulatoires atteints de la COVID-19. Nous avons suivi grâce à ce logiciel 129 patients avec un diagnostic de la COVID-19 confirmé par prélèvement PCR nasopharyngé entre le 29/022020 et le 18/05/2020. Des auto-questionnaires ont été remplis en ligne, après recueil des antécédents et des données sociodémographiques, pour surveiller la survenue de symptômes respiratoires (fréquence respiratoire, température, essoufflement au repos, essoufflement à l’effort, fatigue, goût, odorat, mal de gorge, douleur thoracique et brûlure thoracique). Résultats La population décrite était de 87 femmes (67 %) et 42 hommes (33 %), avec une médiane d’âge de 42,2 ans. Vingt-huit personnes (24 %) étaient en surpoids dont 19 (16 %) obèses (IMC > 30), 15 (11,6 %) étaient immunodéprimés, 20 (15,5 %) avaient des troubles respiratoires chroniques préexistants, 3 (2,3 %) des antécédents cardiovasculaires, 5 étaient diabétiques, 12 avaient une hypertension artérielle et 2 une dyslipidémie. Les 129 patients ont été suivis initialement sur MH Link pendant une médiane de 31 jours (écart interquartile : 24–33 jours) à partir du j0 de leur diagnostic. Neufs personnes (8 %) ont été hospitalisées. Après évaluation le 13/07/2020, les 129 personnes ont été contactées par téléphone afin d’évaluer leur évolution clinique. Cinquante-cinq (42,3 %) d’entre elles n’étaient plus symptomatiques et étaient considérées guéries. Une personne était décédée. Dix-sept (13,1 %) personnes n’avaient pas répondu. Cinquante-six (43,08 %) étaient encore symptomatiques à la réévaluation (asthénie intense, n = 14 ; anosmie/agueusie, n = 21, symptômes respiratoires, n = 15, anxiété/dépression n = 5, céphalées n = 6, atteinte cutanée, n = 3). Conclusion Dans cette cohorte de personnes COVID-19 jeunes, la fréquence de l’hospitalisation était de 8 %. La persistance d’une symptomatologie était fréquente plusieurs semaines après leur COVID-19. Un suivi au long cours, y compris des formes non hospitalisées, semble nécessaire.

Abstract
The usefulness of PSA density (PSAD) was evaluated in relation to the volume of the transitional zone (PSAT) and PSA excess. With this purpose we conducted a study including 27 patients diagnosed as having prostatic cancer (PC) and 46 patients with benign prostatic hypertrophy (BPH). In all of them, the PSA concentration in the serum was determined as well as the total prostatic volume and the transitional zone volume; digital rectal examination (DRE) was also performed. The major diagnostic efficacy was obtained with the excess of PSA (73%, cutoff = -13 ng/ml), followed by DRE (68%), PSAT (64%, cutoff = 0.5), PSAD (64%, cutoff = 0.2), and lastly PSA and ultrasonography (60%). Multivariate analysis (logistic regression) demonstrated PSA excess and DRE to be the best predictors. The model obtained by regression shows the best positive predictive value, and PSA excess the best negative predictive value. Consequently, PSA excess could be relevant in prostate cancer diagnosis.

Abstract
Common single-nucleotide polymorphisms (SNPs) account for a large proportion of the heritability of obsessive-compulsive disorder (OCD). Co-ocurrence of OCD and schizophrenia is commoner than expected based on their respective prevalences, complicating the clinical management of patients. This study addresses two main objectives: to identify particular genes associated with OCD by SNP-based and gene-based tests; and to test the existence of a polygenic risk shared with schizophrenia. The primary analysis was an exon-focused genome-wide association study of 370 OCD cases and 443 controls from Spain. A polygenic risk model based on the Psychiatric Genetics Consortium schizophrenia data set (PGC-SCZ2) was tested in our OCD data. A polygenic risk model based on our OCD data was tested on previous data of schizophrenia from our group. The most significant association at the gene-based test was found at DNM3 (P=7.9 × 10(-5)), a gene involved in synaptic vesicle endocytosis. The polygenic risk model from PGC-SCZ2 data was strongly associated with disease status in our OCD sample, reaching its most significant value after removal of the major histocompatibility complex region (lowest P=2.3 × 10(-6), explaining 3.7% of the variance). The shared polygenic risk was confirmed in our schizophrenia data. In conclusion, DNM3 may be involved in risk to OCD. The shared polygenic risk between schizophrenia and OCD may be partially responsible for the frequent comorbidity of both disorders, explaining epidemiological data on cross-disorder risk. This common etiology may have clinical implications.

Abstract
Computed tomography (CT) and low-field magnetic resonance imaging (MRI) were used to scan seven by-caught dolphin cadavers, belonging to two species: four common dolphins (Delphinus delphis) and three striped dolphins (Stenella coeruleoalba). CT and MRI were obtained with the animals in ventral recumbency. After the imaging procedures, six dolphins were frozen at -20°C and sliced in the same position they were examined. Not only CT and MRI scans, but also cross sections of the heads were obtained in three body planes: transverse (slices of 1 cm thickness) in three dolphins, sagittal (5 cm thickness) in two dolphins and dorsal (5 cm thickness) in two dolphins. Relevant anatomical structures were identified and labelled on each cross section, obtaining a comprehensive bi-dimensional topographical anatomy guide of the main features of the common and the striped dolphin head. Furthermore, the anatomical cross sections were compared with their corresponding CT and MRI images, allowing an imaging identification of most of the anatomical features. CT scans produced an excellent definition of the bony and air-filled structures, while MRI allowed us to successfully identify most of the soft tissue structures in the dolphin's head. This paper provides a detailed anatomical description of the head structures of common and striped dolphins and compares anatomical cross sections with CT and MRI scans, becoming a reference guide for the interpretation of imaging studies.

Abstract
To report the results obtained with the transobturator sub-urethral tape (TOT) for the surgical treatment of stress urinary incontinence (SUI) after 1 year follow-up. Ninety-three patients diagnosed with SUI or mixed urinary incontinence (MUI) underwent a TOT procedure associated to prolapse surgery, if necessary. Pre-operative quality of life (QoL) was assessed with the Urogenital Distress Inventory Short Form (UDI-6)/Incontinence Impact Questionnaire Short Form (IIQ-7) questionnaires. Surgical and early complications were monitored. A stress test and an urodynamic test if urge incontinence de novo appeared were performed at 1 year follow-up. UDI-6/IIQ-7 questionnaires and SUI symptoms were recorded. Patients' characteristics, pre-operative quality of life and urodynamic evaluation were similar in the TOT and in the pelvic floor surgery group. From the sample, 15% had post-operative retention and 10% had vaginal erosion. The global rate of objective cure was 97% in both groups. The scores of the QoL questionnaires were worse by 9% and 10% with the procedure, respectively. Patients with urodynamic (MUI) or persistence of SUI symptoms (10%) did not reach a significant improvement, although patients with urge incontinence de novo (10%) did. The TOT procedure is safe and effective. Results showed that the association to pelvic floor surgical techniques did not diminish 1 year later. The stress test outcome assessment can overestimate the results, compared to the QoL assessment. In our report, the MUI did not improve with this surgical approach. Our results highlight the necessary employment of both the objective testing and the patient's opinion of her symptoms during daily life.

Abstract
12031 Background: Human tumor xenografts in mice can be remarkably predictive of response in humans to cytotoxic chemotherapeutic drugs. Tumor endothelial cells are sensitive to the action of conventional cytotoxic drugs when they are regularly administrated at low doses. This concept, known as metronomic chemotherapy, has been demonstrated in preclinical studies using transplanted tumor models. We aim to investigate the potential anti-tumoral activity of Gemcitabine (G) when administered in a low-dose schedule in an ortothopic implantation model of human pancreatic carcinomas. Methods: Standard gemcitabine schedule: NP18 tumor orthotopically implanted nude mices were randomly distributed to experimental (n = 13, G100 mg/kg intraperitoneally on days 0, 3, 6 and 9 post-implantation) and control group (n = 13, saline). Animal were sacrificed after 4 weeks and we compared weigths (grams) and volume (cm3) of tumors betwen the two groups by the Mann-Whitney U test. Metronomic schedule: After a toxicological study an optimal metronomic dose of 1 mg G /kg per day was chosen. Thirty xenografted mices were randomly distributed to experimental group (n = 15, intraperitoneal G1 mg/kg) and control group (n = 15, saline) and treated for 30 days. Animal were analysed as described before. Results: Standard schedule: Tumor weight mean of treatment group was 0.01 grams ± 0.01 versus 0.54 grams ± 0.48 of the control group. Tumor volume mean in G group was 0.01 cm 3 ± 0.01 versus 0.51 cm 3 ± 0.67) in the control group.Treatment significantly inhibited NP18 tumour growth (p < 0.001). No differences in mice weight were observed between both groups. Metronomic schedule: Tumor weight mean in the treatment group was 0.04 grams ± 0.08 versus 0.53 grams ± 0.46 in control group. Tumor volume mean in G group was 011 cm 3 ± 0.19 versus 0.37 cm 3. Treatment with low-dose of G significantly inhibited NP18 tumour growth (p < 0.003). There were no differences in mice weight between the two groups. Conclusions: Our data show that G administered in a metronomic schedule is effective in inhibiting the growth of NP18 tumor orthotopically implanted in the nude mice. We now aim to study the angiogenic profile of tumors receiving the standard and metronomic schedule and to set up a new experiment to compare survival benefit in the animal model. No significant financial relationships to disclose.

Abstract
This work shows the study performance to intestinal enterolithis from a 91 year old patient with multiple enterolithiasis confirmed by abdominal X-ray and TAC analyses showing the presence of intestinal, renal and bile stones. This enterolithis is associated with colon adenocarcinoma. The enteroliths were obtained by hemicolectomia and were analyzed by infrared spectroscopy (IR), giving non-stoichiometry carbonate apatite whitloquite-like with, possibly, organic material. By atomic emission spectroscopy we found Ca, Mg, K, Na and K (mg/100 mg of calculi) and Zn, Ba, Mn, Fe, Cu, Si, Ti and Br in minor proportion (microg/100 mg of calculi). Because of calculi morphology and the IR spectra (non-stoichiometry carbonate apatite) we carried out analysis by high performance liquid chromatography (HPLC) and found coproporphyrin (about microg/g of calculi) and uroporphyrin, protoporphyrin and heptacarboxy-porphyrin in minor extent. Calculi were also studied by scanning electronic microscopy and EDX and X-ray diffraction giving crystals of CaP4O11. All these results show that intestinal enteroliths composition are similar to renal calculi although its morphology differs from renal calculi.

Abstract
Genes for an isoamylase-like debranching enzyme have been isolated from rice and Aegilops tauschii, the donor of the D genome to wheat. The structures of the genes are very similar to each other and to the maize SU1 isoamylase gene and consist of 18 exons spread over approximately 7.5 kb. Southern analysis and fluorescent in situ hybridization showed the Ae. tauschii gene to be located in the proximal region of the short arm of chromosome 7D, thus showing synteny with the localization of the rice isoamylase gene on rice chromosome 8. Analysis of the expression pattern of wheat sugary isoamylase genes indicates that they are strongly expressed in the developing endosperm 6 days after flowering. Three distinct Sugary-type cDNA sequences were isolated from the wheat endosperm that are likely to correspond to the products of the three genomes. The deduced amino acid sequence of rice and wheat Sugary-type isoamylase is compared with other sequences available in the database and the results demonstrate that there are three types of isoamylase sequences in plants: those containing 18 exons (the Sugary-type isoamylase gene), those containing 21 exons, and those containing only 1 exon. It is possible that different combinations of isoamylase genes are expressed in different tissues.

Abstract
Differential aspects of the host immune response generated by Trypanosoma cruzi infection were examined in two different mouse strains, BALB/c (haplotype H2-Kd) which does not overcome the acute phase of the infection and C57BL/6 (haplotype H2-Kb) which survives to the acute phase. After infection an increase in CD3+ T cells was observed in both mouse strains in the peritoneal cavity. However, while the CD3+ T cells from the BALB/c mice showed an increase in the IL-4 cytokine expression level, the same type of cells from the C57BL/6 mice showed an increase in IFN-gamma expression. In addition, only the macrophages from the C57BL/6 mice were activated secreting IL-12 and TNF-alpha and producing, moreover, high levels of nitrites. It was observed that also after parasite infection the expression of macrophage and dendritic cells CD40 and CD86 co-stimulation molecules from the spleen were diminished in BALB/c but not in C57BL/6 mice. In correlation with this observation the macrophages from the spleen of infected BALB/c mice secreted lower concentrations of nitrites than the C57BL/6 mouse cells. Also, the spleen dendritic cells from infected BALB/c mice had a small potential to present alloantigens in contrast to that observed in the infected C57BL/6 mouse cells.

Abstract
OBJECTIVES Dysregulation of normal programmed cell death mechanisms plays an important role in the pathogenesis of breast cancer. The purpose of this study was to investigate the role of bax and p53 expression in tumorigenesis and progression of breast carcinoma as well as their relationship with proliferative and apoptotic activity. METHODS We used immunohistochemical methods and in situ detection of apoptotic cells to examine 30 carcinomas in situ (CIS), 131 invasive breast carcinomas and 45 lymph node metastases. RESULTS In 25% (33 of 131) of invasive breast carcinomas examined, bax expression was absent, while p53 accumulation was present in 37% (49 of 131). Interestingly, p53 accumulation and loss of bax expression occur in breast CIS as frequently as in invasive breast carcinoma. Thus, in 17% (5 of 30) of CIS bax expression was absent, and 30% (9 of 30) presented nuclear expression of p53. p53 accumulation was related to apoptosis and proliferative activity. However, the protein level of bax was unrelated to all parameters studied, including proliferation and apoptosis of tumor cells. A multivariate analysis of disease-free survival demonstrated that p53 accumulation and bax expression are not significant independent indicators of prognosis in operable breast carcinoma. Our results also show that the proportion of bax- and p53-positive cells does not vary between primary and metastatic tumors. CONCLUSIONS p53 accumulation and loss of bax expression influence the acquisition of a malignant phenotype but seem to have no further impact on tumor progression.

Abstract
Mutant alleles with the 677C-->T and 1298A-->C polymorphisms of the MTHFR gene, and consequent lower methylentetrahydrofolate reductase enzyme activity, have been related to higher plasma homocysteine levels, which are associated with cardiovascular diseases. We assessed the genotype frequencies, degrees of fertility and homocysteine levels, and discuss a possible genetic selection for the gene polymorphisms studied. A total of 1777 subjects (897 women and 880 men), divided into four age groups, were genotyped by PCR and restriction fragment length polymorphism. The total homocysteine concentration in plasma was determined by fluorescence polarization immunoassay. Based on random pairs and linkage disequilibrium of the two polymorphisms, we estimated the rate of fetal non-viability according to the combinations of these two polymorphisms to be 4.63% for the group >24 years old and 6.31% for the group <24 years old. We detected an increased frequency of mutant alleles in the youngest age group, coincident with a generally increased folate intake by pregnant women in Spain. The genetic selection detected leads to an increase in mutated individuals, the number of whom could increase four-fold over the next 75 years. Although generally reduced in the younger age groups, the homocysteine plasma levels were shown to increase in individuals according to the number of mutations, especially those of the 677T allele.

Abstract
INTRODUCTION AND OBJECTIVES Early detection of cardiovascular disease is a major goal of contemporary medicine in efforts to prevent coronary heart disease. The goal of this study was to look for a number of changes that could be detected in the neurons of the 19 Brodman area by means of chromatic computerized analysis (CCA) as a consequence of a neurobiological dysfunction, which induced a failure in the chromatic perception, which, in turn, expressed the existence of hypercholesterolemia through numeric qualification and therefore, a cardiovascular risk. PATIENTS AND METHOD . We studied 208 patients (Group 1) (153 men and 55 women) with pre-study plasma cholesterol levels in excess of 200 mg/dl. The control group (Group 2) also consisted of 208 subjects (153 men and 55 women) but with a cholesterol level below 200 mg/dl. They were performed by CCA, previously ruling out any systemic or ophthalmological pathology. RESULTS All global indexes were highly correlated in both groups. The direct relation between cholesterol levels and 19 area, reached a canonical correlation of 0.825 with a sensitivity of 90% and especifity of 93%. The results of the multiple regression taking total cholesterol as a dependent variable and the most significative parameter of CCA, as an independent variable was R = 0.89 (p < 0.001), with a test variability of 81%. CONCLUSIONS This study determines a strong association between hypercholesterolemia and the visual areas of the cerebral cortex.

Abstract
Protein phosphorylation is involved in sperm capacitation, so the effect of protein phosphatase inhibitors on the capacitation of spermatozoa of males with unexplained infertility was investigated. d-mannose ligand specific receptor expression in fresh, living spermatozoa, capacitated or treated with calyculin A (an inhibitor of protein phosphatases 1 and 2A), was studied in three groups of men: pre-vasectomy (fertile) males, males in couples with male infertility, and males in couples with infertility of unknown aetiology. Flow cytometry showed significant differences between infertile couples with a male factor and fertile couples (P < 0.05), both after capacitation and after treatment with calyculin A. In the group of couples with infertility of unknown aetiology (n = 15), d-mannose receptor expression was diminished in six cases after classical capacitation. However, when the spermatozoa of these six men were treated with calyculin A, five showed an increased specific d-mannose receptor expression. From these results it is suggested that in vitro treatment of spermatozoa with inhibitors of protein phosphatases may be of great value in some cases of unexplained infertility.

Abstract
Clusterin has been implicated in numerous processes including active cell death, immune regulation, cell adhesion and morphological transformation. The purpose of this study was to examine clusterin expression in a large series of breast carcinomas by immunohistochemistry and in situ hybridization. The study included 40 samples of non-neoplastic glandular epithelia, 42 benign lesions, 15 atypical intraductal hyperplasias, 35 carcinomas in situ, 114 invasive carcinomas, and lymph node metastases from 40 patients. Epithelial normal cells were always negative for clusterin expression and only 19% of the benign lesions presented positive staining. In contrast to the benign lesions, however, the frequency of clusterin positive samples increased in atypical hyperplasias (47%, P = 0.08), intraductal carcinomas (49%, P = 0.01) and invasive carcinomas (53%, P < 0.001). Positive staining presented a cytoplasmic pattern, except in 3 cases of invasive carcinomas which had nuclear staining. Clusterin mRNA by in situ hybridization confirmed the specific cellular pattern of clusterin expression by immunohistochemistry. Clusterin expression was associated with large tumor size (P = 0.04), estrogen and progesterone receptor negative status (P = 0.02 and P = 0.001, respectively) and with the progression from primary carcinoma to metastatic carcinoma in lymph nodes (80% metastatic nodes had positive expression) (P = 0.004). Ten of 15 (67%) primary carcinomas without clusterin expression became positive in lymph node metastases, while most (22 of 25, 88%) of the clusterin-positive primary carcinomas were also immunoreactive in metastases. In survival analysis, clusterin expression did not represent a prognostic indicator by uni- or multivariate analysis. The increased clusterin expression in breast carcinomas tended to correlate inversely with the apoptotic index (P = 0.09) which indicates that clusterin gene expression is not a prerequisite to cellular death by apoptosis. From these results, we suggest that clusterin may have a role in tumorigenesis and progression of human breast carcinomas.

Abstract
DNA sequence analysis of the protein S gene (PROS1) in 22 Spanish probands with type I or III PS deficiency, has allowed the identification of 10 different mutations and 2 new sequence variants in 15 probands. Nine of the mutations, 8 of which are novel, cosegregate with type I or quantitative PS deficiency in 12 of the 13 pedigrees analyzed. One of these mutations (Q238X) also cosegregates with both type I and III PS-deficient phenotypes coexisting in a type I/III pedigree. Another mutation identified in a pedigree with these two PS phenotypes is the missense mutation R520G, present in the homozygous form in the type I propositus and in the heterozygous form in his type III relatives. By contrast, no cosegregating PROS1 mutation has been found in any of the six families with only type III phenotypes. Three of these families, as well as the two families with type I and I/III phenotypes where no other PROS1 mutation has been identified, segregate the P allele of the S460P variant, although this allele does not always cosegregate with the deficient phenotype. From these results we conclude that while mutations in PROS1 are the main cause of type I PS deficiency, the molecular basis of the type III phenotype is probably more complex, with many cases not being explained by a PROS1 mutation.

Abstract
Anticoagulant protein S (PS) deficiency is a known risk factor for thrombophilia. The structure and high allelic heterogeneity of the PS gene (PROS1), together with the presence of a 97% homologous pseudogene, complicates PROS1 analysis. We have optimized a simple, fast, and non-isotopic Single-Strand Conformation Analysis (SSCA or SSCP) method for PROS1 mutation detection. This is accomplished through the analysis of the single-stranded and heteroduplex DNA fragments corresponding to 15 PCR segments that include part of the 5'-upstream region and the 15 PROS1 exons with their intron boundaries. To standardize the method, 13 known PROS1 mutations or allele variants in 10 different fragments were analyzed under different electrophoretic conditions. The results indicated that, using a combination of two different electrophoretic settings, all the allele variants could be detected as a single-strand band shift and/or by the presence of a heteroduplex. This method was used to analyze the PROS1 gene in 31 propositi with different types of PS deficiency and thrombosis. Ten different cosegregating mutations, seven of which are novel (143C->G, L-27H, G96X, M599T, P626L, 1418delA, and 1877delT), were identified in the five families suffering from type I or quantitative PS deficiency and in four of the nine families with coexistence of type I and type III phenotypes. No clearly co-segregating PROS1 mutations were identified in any of the 17 type III propositi analyzed, although eight of them were heterozygotes for the uncommon P460 allele of the S/P460 variant. Furthermore, five apparently neutral allelic variants, three of which are novel (-296C->T, 182G->C and T57S), were identified in a normal control, two type I/III and two type III PS-deficient pedigrees.

Abstract
Myotonic muscular dystrophy (MMD) is a genetic disease caused by a defective enzyme, myotoninkinase. Male patients with MMD are reported to have reduced fertility. The purpose of this work was to study sperm capacitation and acrosome reaction in the ejaculates of sterile males with MMD and of healthy males (control group). The expression of the specific D-mannose receptors was explored by microscopic examination and by flow cytometry analysis. In addition, the binding patterns of Pisum sativum (PSA) lectin to acrosome content and outer acrosomal membrane in the spermatozoa of each group were analysed. Both the capacitation and the acrosome reaction in the spermatozoa of the MMD group were deficient and these findings strongly suggest that these anomalies may account for the sterility of these patients.

Abstract
The multifactorial character of thrombotic disease is shown in a Spanish pedigree in which the propositus, with recurrent deep vein thrombosis, inherited the factor V R/Q506 mutation, the prothrombin 20210G/A variant and type III Protein S deficiency. Among 14 relatives carrying one or two of these three risk factors, thrombosis is present in a heterozygote for R/Q506 and in another for 20210G/A, who also had slightly positive antiphospholipid antibodies. Type I PS deficiency was also found in a young asymptomatic woman. PROS1 analysis showed coexistence of type III and type I PS deficiency to be associated with heterozygosity and homozygosity, respectively, for the P460 or PS Heerlen allele of the S/P460 variant. Analysis of PS values in this and other pedigrees segregating this variant revealed that not only free but also mean total PS levels are slightly but significantly lower in the SP460 heterozygotes than in the SS460 homozygotes. These findings strongly suggest a role of the P460 variant in the expression of the PS deficient phenotype.

Abstract
Plant alpha-1,4 glucanotransferases (disproportionating enzymes, or D-enzymes) transfer glucan chains among oligosaccharides with the concomitant release of glucose (Glc). Analysis of Chlamydomonas reinhardtii sta11-1 mutants revealed a correlation between a D-enzyme deficiency and specific alterations in amylopectin structure and starch biosynthesis, thereby suggesting previously unknown biosynthetic functions. This study characterized the biochemical activities of the alpha-1,4 glucanotransferase that is deficient in sta11-1 mutants. The enzyme exhibited the glucan transfer and Glc production activities that define D-enzymes. D-enzyme also transferred glucans among the outer chains of amylopectin (using the polysaccharide chains as both donor and acceptor) and from malto-oligosaccharides into the outer chains of either amylopectin or glycogen. In contrast to transfer among oligosaccharides, which occurs readily with maltotriose, transfer into polysaccharide required longer donor molecules. All three enzymatic activities, evolution of Glc from oligosaccharides, glucan transfer from oligosaccharides into polysaccharides, and transfer among polysaccharide outer chains, were evident in a single 62-kD band. Absence of all three activities co-segregated with the sta11-1 mutation, which is known to cause abnormal accumulation of oligosaccharides at the expense of starch. To explain these data we propose that D-enzymes function directly in building the amylopectin structure.

Abstract
We describe a novel mutation in the Chlamydomonas reinhardtii STA11 gene, which results in significantly reduced granular starch deposition and major modifications in amylopectin structure and granule shape. This defect simultaneously leads to the accumulation of linear malto-oligosaccharides. The sta11-1 mutation causes the absence of an alpha-1,4 glucanotransferase known as disproportionating enzyme (D-enzyme). D-enzyme activity was found to be correlated with the amount of wild-type allele doses in gene dosage experiments. All other enzymes involved in starch biosynthesis, including ADP-glucose pyrophosphorylase, debranching enzymes, soluble and granule-bound starch synthases, branching enzymes, phosphorylases, alpha-glucosidases (maltases), and amylases, were unaffected by the mutation. These data indicate that the D-enzyme is required for normal starch granule biogenesis in the monocellular alga C. reinhardtii.

Abstract
In vascular plants, mutations leading to a defect in debranching enzyme lead to the simultaneous synthesis of glycogen-like material and normal starch. In Chlamydomonas reinhardtii comparable defects lead to the replacement of starch by phytoglycogen. Therefore, debranching was proposed to define a mandatory step for starch biosynthesis. We now report the characterization of small amounts of an insoluble, amylose-like material found in the mutant algae. This novel, starch-like material was shown to be entirely dependent on the presence of granule-bound starch synthase (GBSSI), the enzyme responsible for amylose synthesis in plants. However, enzyme activity assays, solubilization of proteins from the granule, and western blots all failed to detect GBSSI within the insoluble polysaccharide matrix. The glycogen-like polysaccharides produced in the absence of GBSSI were proved to be qualitatively and quantitatively identical to those produced in its presence. Therefore, we propose that GBSSI requires the presence of crystalline amylopectin for granule binding and that the synthesis of amylose-like material can proceed at low levels without the binding of GBSSI to the polysaccharide matrix. Our results confirm that amylopectin synthesis is completely blocked in debranching-enzyme-defective mutants of C. reinhardtii.

Abstract
Molecular characterization of HLA class II expression was investigated in five lung tumour cell lines at the protein and mRNA levels. The cell lines exhibited a differential expression of HLA-DR, HLA-DP and HLA-DQ products and also showed differences in the inducibility of HLA class II genes by gamma-IFN. Gamma-IFN stimulation induced only HLA-DR expression to varying degrees in three cell lines, while only one cell line showed stimulation for HLA-DP and none for HLA-DQ antigens. These results suggest locus-specific regulation for the three loci. The presence of DR protein on the cell-surface membrane was always positively correlated with the presence of HLA-DR mRNA in the cells. After treatment with 5-azacytidine in the A549 cell line, which expressed the lowest values, there was no effect on HLA class II levels. This suggested that methylation does not play an important role in the lack of MHC class II antigen expression. In addition to studying mRNA levels of HLA class II antigens, we analysed mRNA of the proto-oncogene c-myc and observed a positive correlation of two mRNA: the increments in HLA-DR expression were associated with increments in c-myc expression. This suggests a relationship between the regulatory and HLA-DR antigens control the expression of c-myc and HLA-DR antigens in lung tumour cell lines.

Abstract
OBJECTIVES To analyze changes in the thyroid function in patients with acute pancreatitis. METHODS Admission serum levels of triiodothyronine (T3), reverse triiodothyronine (rT3), thyroxine (T4) and thyrotropin (TSH) were determined in 20 patients with pancreatitis and 20 healthy control patients. Another group of 20 patients with upper digestive haemorrhage was included to study possible changes in the pattern of thyroid function in hemodynamic alterations. In addition, laboratory indicators of liver, renal and pancreatic functions were measured in all groups. RESULTS Our results demonstrated low levels of T3 in 20% of patients with pancreatitis and increased rT3 levels in 75% of them. Thyrotropin was always among reference ranges and only one case presented a low level of T4. No significant alterations were detected in patients with upper digestive haemorrhage. CONCLUSIONS These results suggest that pancreatitis may play a role in the genesis of these changes, since other factors such as diet and cellular hepatic alteration appear to have had no effect on the levels of thyroid hormones in these patients. In other studies those changes in the thyroid function can be relationed with the prognosis in acute pancreatitis.

Abstract
In experimental systems, an association between K-ras activity and expression of major histocompatibility complex (MHC) molecules has been reported. In this study, 52 surgically resected bronchogenic carcinomas were studied for human leukocyte antigen (HLA) class I and II expression, and for the presence of point mutations in codon 12 of the K-ras gene. HLA class I loss was detected in 18 carcinomas, and most of the tumors (43 cases) were found negative for HLA class II antigen expression by the APAAP technique with specific monoclonal antibodies. Analysis using the polymerase chain reaction (PCR), together with selective hybridization using mutation-specific synthetic oligonucleotides, demonstrated K-ras mutations in five cases, all of them corresponding to the adenocarcinoma subtype (31.2% of the adenocarcinomas included in our study) with a poor degree of differentiation. We did not find any correlation between K-ras mutations and HLA class I and II expression in bronchogenic carcinomas. Therefore, it would appear that downregulation of MHC antigens by point mutations of K-ras does not take place in vivo.

Abstract
INTRODUCTION In some patients it was seen that chronic headaches disappeared after laser iridectomies had been done to prevent glaucoma, in persons with normal intra-ocular pressure (IOP). OBJECTIVE To make a study of patients with headache, some of whom were treated with topical beta-blockers (carteolol) and others by Yag-laser iridectomies. The effect on headache and IOP was analyzed. MATERIAL AND METHODS A survey, ophthalmological examination and headache provocation test were carried out in patients with headaches, and the changes in IOP determined by pharmacologically inducing miosis and mydriasis were recorded. Three treatment groups were formed and the results analyzed statistically. RESULTS In the 12 patients treated pharmacologically, 62% improved and in 14% the headaches disappeared. In the 16 treated using laser 94% were cured and 6% improved. When both types of treatment were used on 9 patients, 22% improved and 78% were cured. The validity of the ocular pressure curve was checked in the diagnosis of blockage of the pupil. CONCLUSIONS Some headaches of ocular origin (ophthalmotonic), not previously described, occur due to abrupt changes in intraocular pressure, and improve significantly when the IOP is reduced by beta-blockers or Yag-laser iridectomies are done. A valid provocation tests for diagnosis of this type of headache is described. We consider that blockage of the pupil and/or of the angle of the anterior chamber are possible etiopathogenic mechanisms.

Abstract
In this study, virion-associated RNA was measured in plasma from twenty six patients in various stages of HIV-1 disease by the additive RT-PCR method. Plasma viral RNA levels were inversely correlated (r = -0.72894) with total CD4+ cell counts and directly (r = 0.86964) with serum titre beta 2-microglobulin in chronically infected patients. This additive RT-PCR is based on a mathematical logistic adjustment of the standard curve and the use of an internal standard identical to the target molecule, which represents a control system for the efficiency of RT-PCR and allows a continuous assessment of the accuracy based on the recovery.

Abstract
Genomic DNA fragments from Triticum tauschii (D-genome donor to wheat) carrying starch branching enzyme I (SBE I) type genes have been characterized. One fragment contains one complete gene and two partial genes in 16 kb of DNA. One of the partial genes is oriented in the opposite strand to the other two. The gene that is complete was sequenced. Its structure corresponds closely to that of rice in that exons 3-8 are retained at similar sizes and spacings. A cDNA closely corresponding to the complete gene was isolated and characterized; it codes for a putative protein that represents a novel type of SBE I, as it is shorter at the 3' end than the forms reported so far in other plants. A second genomic fragment contains a different SBE I gene. There appear to be approximately 10 copies of SBE I type genes in wheat (approximately 5 in T. tauschii) and most of them have been assigned to group 7 chromosomes. In situ hybridization indicates that a major locus for the genes is located at the distal end of the short arm of chromosome 7D.

Abstract
OBJECTIVE To evaluate the efficiency of PSA excess in distinguishing prostate cancer (PC) in its early stages from benign prostatic hypertrophy (BPH) and compare it with the efficiency of serum PSA. METHODS A cross-sectional study was carried out on 27 patients with PC and 46 with BPH, whose serum PSA and prostatic volume were determined. PSA excess was calculated as the difference between serum PSA and predicted PSA according to the gland volume, calculating the latter as the prostatic volume multiplied by factor 0.3 ng/ml/g. RESULTS PSA excess values were significantly higher in patients with PC, while serum PSA levels were not different between the two populations studied. Receiver operating curves (ROC plots) showed a higher diagnostic utility for PSA excess, with a maximum efficiency of 73% at a cut-off point of -13 ng/ml. The predictive value of a positive result is slightly higher for serum PSA, but PSA excess showed a predictive value of a negative result superior to that of PSA.

Abstract
To elucidate the molecular basis of hereditary protein S (PS) deficiency and, in particular, type III or free PS deficiency, the allelic distribution and segregation patterns of the PS gene (PROS1) polymorphisms P626A/G and S460P (PS Heerlen) have been analyzed in a group of 45 proposita suffering from type I or type III PS deficiency. No differences between patients and controls were found in the frequency of the P626A/G alleles. By contrast, the frequency of the PS Heerlen allele in the group of patients with type III PS deficiency (9 of 46 chromosomes, P = .196) was significantly higher (P < .001) than in the control group (1 of 300 chromosomes, P = .003). The A allele of P626A/G was always associated with the P allele of S460P. However, this haplotype did not co-segregate with the type III PS-deficient phenotype in 3 of the families. Furthermore, multipoint linkage analysis excluded the whole PROS1 gene in 1 of these families, which is in agreement with the absence of mutations in the PROS1 gene, as determined by sequence analysis. Finally, linkage analysis with 4 microsatellite markers linked to the C4BPB and C4BPA loci also excluded these two genes. From these results we conclude that, at least in some families, the molecular basis of type III PS deficiency is not due to the Mendelian inheritance of a single defect in the PROS1 or in the C4BP genes.

Abstract
Sixty patients undergoing gynecological surgery under enflurane nitrous-oxide anesthesia were studied. The goal was to investigate the effects of the degree of surgical trauma and glucose load on the pattern of TSH, GH and PRL secretion before, during and following surgery. For this purpose the patients were divided into four groups according to the severity of the operation and the type of fluid administered. The groups were as follows: group 1, major surgery--glucose solution; group II, major surgery--lactated Ringer solution; group III, minor surgery--glucose solution; group IV, minor surgery--no intravenous fluids. The three hormone concentrations, 45 min after the start of anesthesia, increased in all groups. The highest values for GH and PRL concentration were observed in group IV. This increase was followed by a decrease 24 h and 5 days after induction, at the end of the study, except in group IV where TSH and GH levels fell back to normal values more slowly. These results lead to the following conclusions: a) Enflurane does not suppress hormonal stress response to surgical trauma; b) A similar pattern is obtained for pituitary response, indicating that a general pituitary stimulus takes place in these situations; c) Glucose load plays an important role in pituitary hormonal response to surgical stress; d) There is no direct relationship between the degree of surgical trauma and the hormone levels in patients under enflurane anaesthesia.

Abstract
We determined the frequency of expression of the major histocompatibility complex antigens HLA-A,B,C in tumor cells from 207 primary tumor lesions of breast and bronchogenic carcinomas, to see if the expression of theses antigens was linked with several clinicopathological parameters associated with tumor aggressivity, such as abnormal cellular DNA content. We compared tumor tissues with nonneoplastic tissues and tissues from 15 benign breast lesions. HLA class I expressor and nonexpressor tumor cells were determined by using immunohistochemical stains (PAP and APAAP methods) and antibodies against these antigens. Reduction of HLA class I antigen was detected in 65 tumors (31.7%) and was significantly associated with poor tumor differentiation and abnormal cellular DNA content (p < 0.001). These characteristics might define a group of aggressive tumors in which the decrease of HLA class I antigens would enable tumor cells to avoid eliciting host immune responses. On the other hand, the altered regulatory mechanisms, of tumors with abnormal cellular DNA content, might modulate the expression of HLA class I molecules.

Abstract
RNA-based studies are an important tool for the identification and functional characterization of mutations underlying inherited disease. These studies could in principle be compromised by 'aberrant splicing' (the generation of alternatively spliced transcripts lacking any obvious function) during normal expression of the genes under investigation. Using a highly sensitive RT-PCR assay, we show here that aberrant splicing is a frequent occurrence during expression of the protein C (PROC) and protein S (PROS) genes. Aberrantly spliced transcripts were present in different cell types including liver, the main expressing tissue for both protein C and protein S. In an attempt to compare individual mRNA splicing patterns, PROC and PROS RNA from easily accessible cells of different healthy control individuals was studied. However, variation between different RT-PCR assays from the same individual precluded both the relative quantitation of the aberrant transcripts and the analysis of interindividual differences. Our findings are consistent with the notion that a low level of aberrantly spliced transcripts are routinely generated during PROC and PROS gene expression. The possibility that these transcripts may complicate the RT-PCR analysis of pathological transcripts must be taken into account when RNA-based strategies of disease analysis are considered.

Abstract
We report the results of protein C gene (PROC) analysis in a Spanish family with hereditary PC deficiency characterized by the presence of three siblings with PC anticoagulant activity levels clearly below 50% of normal and PC antigen and amidolytic activities between 50 and 75% of normal. Their parents are first cousins and have PC levels between 50 and 80% of normal. Sequence analysis of the whole coding sequence of the PROC gene revealed that the three siblings are double homozygotes for a G to A transition at nucleotide 3203 that replaces arginine 87 by histidine (R87H) and for another G to A transition at nucleotide 7054, in intron 7 (7054G --> A). Both parents and one sister were found to be double heterozygotes for these two mutations. Screening for the intronic mutation in a control group and RT-PCR cDNA studies from ectopically transcribed mRNA indicated that 7054G --> A is most likely a rare but neutral DNA variant. These results and the fact that heterozygosity for the missense R87H mutation has also been found associated with a slightly decreased PC anticoagulant activity in another Spanish family, lead us to conclude that homozygosity for R87H is responsible for the PC deficient phenotype in these three siblings.
