Abstract
Non-alcoholic fatty liver disease (NAFLD) is a growing health problem due to the increased obesity rates, among other factors. In its more severe stage (NASH), inflammation, hepatocellular ballooning and fibrosis are present in the liver, which can further evolve to total liver dysfunction or even hepatocarcinoma. As a metabolic disease, is associated to environmental factors such as diet and lifestyle conditions, which in turn can influence the epigenetic landscape of the cells, affecting to the gene expression profile and chromatin organization. In this study we performed ATAC-sequencing and RNA-sequencing to interrogate the chromatin status of liver biopsies in subjects with and without NASH and its effects on RNA transcription and NASH etiology. NASH subjects showed transcriptional downregulation for lipid and glucose metabolic pathways (e.g., ABC transporters, AMPK, FoxO or insulin pathways). A total of 229 genes were differentially enriched (ATAC and mRNA) in NASH, which were mainly related to lipid transport activity, nuclear receptor-binding, dicarboxylic acid transporter, and PPARA lipid regulation. Interpolation of ATAC data with known liver enhancer regions showed differential openness at 8 enhancers, some linked to genes involved in lipid metabolism, (i.e., FASN) and glucose homeostasis (i.e., GCGR). In conclusion, the chromatin landscape is altered in NASH patients compared to patients without this liver condition. This alteration might cause mRNA changes explaining, at least partially, the etiology and pathophysiology of the disease.

Abstract
Background Microglial dysfunction plays a causative role in Alzheimer's disease (AD) pathogenesis. Here we focus on a germline insertion/deletion variant mapping SIRPβ1, a surface receptor that triggers amyloid-β(Aβ) phagocytosis via TYROBP. Objective To analyze the impact of this copy-number variant in SIRPβ1 expression and how it affects AD molecular etiology. Methods Copy-number variant proxy rs2209313 was evaluated in GERALD and GR@ACE longitudinal series. Hippocampal specimens of genotyped AD patients were also examined. SIRPβ1 isoform-specific phagocytosis assays were performed in HEK393T cells. Results The insertion alters the SIRPβ1 protein isoform landscape compromising its ability to bind oligomeric Aβ and its affinity for TYROBP. SIRPβ1 Dup/Dup patients with mild cognitive impairment show an increased cerebrospinal fluid t-Tau/Aβ ratio (p = 0.018) and a higher risk to develop AD (OR = 1.678, p = 0.018). MRIs showed that Dup/Dup patients exhibited a worse initial response to AD. At the moment of diagnosis, all patients showed equivalent Mini-Mental State Examination scores. However, AD patients with the duplication had less hippocampal degeneration (p < 0.001) and fewer white matter hyperintensities. In contrast, longitudinal studies indicate that patients bearing the duplication allele show a slower cognitive decline (p = 0.013). Transcriptional analysis also shows that the SIRPβ1 duplication allele correlates with higher TREM2 expression and an increased microglial activation. Conclusions The SIRPβ1 internal duplication has opposite effects over MCI-to-Dementia conversion risk and AD progression, affecting microglial response to Aβ. Given the pharmacological approaches focused on the TREM2-TYROBP axis, we believe that SIRPβ1 structural variant might be considered as a potential modulator of this causative pathway.

Abstract
Genome-wide association studies (GWAS) constitute a powerful tool to identify the different biochemical pathways associated with disease. This knowledge can be used to prioritize drugs targeting these routes, paving the road to clinical application. Here, we describe DAGGER (Drug Repositioning by Analysis of GWAS and Gene Expression in R), a straightforward pipeline to find currently approved drugs with repurposing potential. As a proof of concept, we analyzed a meta-GWAS of 1.6 × 107 single-nucleotide polymorphisms performed on Alzheimer's disease (AD). Our pipeline uses the Genotype-Tissue Expression (GTEx) and Drug Gene Interaction (DGI) databases for a rational prioritization of 22 druggable targets. Next, we performed a two-stage in vivo functional assay. We used a C. elegans humanized model over-expressing the Aβ1-42 peptide. We assayed the five top-scoring candidate drugs, finding midostaurin, a multitarget protein kinase inhibitor, to be a protective drug. Next, 3xTg AD transgenic mice were used for a final evaluation of midostaurin's effect. Behavioral testing after three weeks of 20 mg/kg intraperitoneal treatment revealed a significant improvement in behavior, including locomotion, anxiety-like behavior, and new-place recognition. Altogether, we consider that our pipeline might be a useful tool for drug repurposing in complex diseases.

Abstract
Purpose Tryptophan is the only precursor of serotonin, the hormone which helps regulate key human functions such as appetite, memory, mood, and sexual behavior. Connections have been identified between serotonin system dysfunction and the molecular etiology and treatment of mood disorders in a wide range of studies. Proposals have been put forward to co-administer tryptophan supplementation together with serotonin reuptake inhibitors in major depression patients, and also to exploit the sub-therapeutic depressive status in healthy populations. The reported responses, however, have been very dissimilar and this uneven effect may largely be explained by interindividual genetic differences. Materials and Methods We studied mood change in 138 healthy subjects using both Goldberg’s General Health Questionnaire and the Profile of Mood States Questionnaire to determine the effects of a daily supplementation of 1g of tryptophan or placebo. Buccal DNA samples were provided and TPH1 (rs1800532), MAOA (rs3788862 and rs979605), MAOB (rs3027452), and COMT (rs6269 and rs4680) variants were genotyped. Results MAOB rs3027452 was equally associated with tryptophan supplementation efficacy in the depression subscales of both questionnaires (ΔT-Score.D; ΔT-Score.TMD and ΔPOMS.D p-values <0.01). Conclusion Here we provide evidence that tryptophan supplementation has an uneven effect on mood improvement in the general population.

Abstract
Background Monoamine oxidase (MAO) activity has been traditionally implicated in blood pressure through its effects on biogenic amine levels such as catecholamines, serotonin, and dopamine. Nowadays, this role is considered relegated to side‐effects such as orthostatic hypotension and/or hypertensive crisis derived from MAO‐inhibitory treatments in patients with psychiatric disease. Methods In the present work we have found an association between a polymorphic variant of MAOB gene and arterial hypertension in obese hypogonadic patients. The study cases comprised a series of 219 nondiabetic males with a body mass index ≥30 kg/m2 and aged <45 years. Hypogonadism was defined as subnormal testosterone concentrations, when free testosterone values ranged <65 pg/ml. Results MAOB rs3027452‐A allele carriers were significantly over‐represented among hypertensive (HT) patients (25.49%) in comparison to either the non‐HT patients (10%, OR = 3.079 CI95 [1.364–6.952], p = .005, Chi‐square test) and the control population series of nonobese nor hypogonadic males (also 10%, p = .003 Chi‐square test). Upon adjusted, an independent association was shown with the hypogonadic group with hypertension when compared with nonhypertensive hypogonadics (Beta = 3.653, p = .005). When quantitative analysis was performed, hypertensive patients harboring rs3027452‐A allele showed higher systolic blood pressure values (p = .038, Mann–Whitney U‐test) as well as an increased Systolic‐Diastolic range despite following HT treatment (∆mmHg 54 vs. 48 for rs3027452‐A and rs3027452‐G respectively, p‐value .019, Mann–Whitney U‐test). Previous studies on MAOB revealed that rs3027452‐A allele has been correlated to a lower activity of the enzyme, what gives a functional evidence over our observation. Conclusion If this result could be extrapolated to other hypertensive patient groups, it would implicate a review of the markers and therapeutic targets on human hypertension.

Abstract
OBJECTIVE From an evolutionary perspective, emotions emerged as rapid adaptive reactions that increase survival rates. Current psychobiology includes the consideration that genetic changes affecting neuroendocrine and neurotransmission pathways may also be affecting mood states. Following this hypothesis, abnormal levels of any of the aminergic neurotransmitters would be of considerable importance in the development of a pathophysiological state. MATERIALS AND METHODS A total of 668 students from the School of Medicine of the University of Malaga (Average = 22.41 ± 3; 41% men) provided self-report measures of mood states using POMS and GHQ-28 questionnaires and buccal cells for genotyping 19 polymorphisms from 14 selected neurotransmitter pathways genes (HTR1A; HTR2A; HTR2C; HTR3B; TPH1; SLC18A1; SLC18A2; COMT; MAOA; MAOB) and neuroendocrine system (AVPR1B; OPRM1; BDNF; OXTR). RESULTS MAOA rs3788862 genotype correlates with decreasing levels of Tension among females (beta = -0.168, p-value = 0.003) but it is neutral among males in this subscale. On the contrary, it correlates with lower GHQ-28 depression scores among males (beta = -0.196, p-value = 0.008). Equivalently, SLC18A1 and HTR2A variants correlated with anger and vigor scores, only among males. From the neuroendocrine system, OPRM1 rs1799971 correlated increasing levels of female's Anxiety, depression and Social Dysfunction scores. CONCLUSION Our findings suggest that these polymorphisms contribute to define general population mood levels, although exhibiting a clear sexual dimorphism.

Abstract
Spermatozoa and neurones share similar membrane characteristics and features. Associations of multiple polymorphisms traditionally related to neurotransmission were investigated. Infertile men were grouped into controls with normospermia (n = 182) and idiopathic infertile men with asthenozoospermia (n = 103), and analysed as a case-control study and as a quantitative association of each genotype. Ten neurotransmission-associated genetic variants were mapped by SNP analysis using quantitative polymerase chain reaction with TaqMan probes. Men with HTR2A rs6313 had a higher risk of asthenozoospermia (OR = 2.14; P = 0.04). MAOA rs3788862 G carriers displayed an increased risk of asthenozoospermia (OR = 2.29; P = 0.02). The SLC18A1 rs1390938 G allele was more frequent among such cases (0.75 versus 0.87; P < 0.01 and P < 0.01 for Armitage trend test); for SLC18A1 rs2270641 P = 0.02 (case-control frequency) and P = 0.01 (Armitage trend test). MAOA rs3788862 was correlated with sperm motility (Spearman ρ = 0.14; P = 0.02); SLC18A1 rs1390938 was correlated with sperm count and motility (Spearman ρ = 0.20; P < 0.01). Gene polymorphisms of HTR2A, MAOA and SLC18A1, related to neurotransmission, are individually associated with asthenozoospermia through variation in sperm count and motility, without detectable allelic or genotype interaction.

Abstract
BACKGROUND Folates are essential nutrients that maintain nucleotide synthesis and methylation reactions. Folate levels depend essentially on the diet. In the present work, the changes in the folate-homocysteine (Hcy) metabolic axis were studied in response to treatment with levofolinic acid. METHODS 49 college students (23 men and 26 women) underwent a treatment voluntarily with 5 mg/day levofolinic acid for one month. Serum and red blood cell folate, vitamin B12, and Hcy levels were determined on days 2, 5, 10, and 30 during treatment and 30 days after completion of treatment. RESULTS Serum folate and Hcy levels showed a plateau beginning on day 10, while red blood cell folate increased towards treatment completion. Gender differences were found in basal levels of Hcy, these differences remaining until the 10th day of treatment and reappearing 30 days after the treatment was finished. Between gender differences in treatment evolution were found only in percentage changes in red blood cell folate in women and men at day 30 of treatment. CONCLUSIONS There is a compartmentalization of folates in the body that presents a plateau in serum and an erythrocyte reservoir. Folate metabolism presents differential features between genders. The greater physiological need for folate in women of childbearing age could be the determining factor in this difference.

MAIN OUTCOME MEASURE(S) Genotype and haplotype analysis of the serotonin transporter-linked polymorphic region (5-HTTLPR), rs1800532, rs6295, rs6313, and rs3813929, between recipients grouped according to the results of the oocyte donation for IVF treatment. RESULT(S) No differences were found between genotype distribution of the tryptophan hydroxylase 1, serotonin receptor 2A, and serotonin receptor 2C polymorphisms. Recipients carrying the LL genotype for 5-HTTLPR had lower clinical pregnancy rates (PR) and higher biochemical pregnancy loss (BPL) events. Lower implantation rates were found in CC carriers for 5-HT1A.rs6295 who also presented higher BPL rates. A lower incidence of clinical pregnancy was observed for LC haplotypes, corresponding to an increase in BPL rates. CONCLUSION(S) A strong association was found between early pregnancy loss and recipients carrying the 5-HTTLPR and rs6295 genetic variants. Identifying biological processes involving serotonin and embryo implantation may help to understand the dynamics of the maternal-embryo dialogue.

Abstract
Human amniotic fluid-derived mesenchymal stromal cells (hAMSC) have become one of the main cell populations used in regenerative medicine and for the study of various clinical disorders. These cells have a great capacity for proliferation and differentiation and do not form teratomas when transplanted into animal models, and their stemness seems to be between embryonic cells and adult mesenchymal cells. Before their use in cell therapy, they must be cultured and expanded in vitro, but the effect this process has on their fitness, a determining factor for the success or failure of cell therapy, is unknown. We undertook a follow-up of gene and microRNAs (miRNAs) expression using microarray of hAMSC for the first 15 passages. Significant changes were noted in the expression of various mRNAs and miRNAs, particularly down-regulation of TP53, increased expression of hsa-miR-125a and up-regulation of CDKN2D . The variations in TP53 and hsa-miR-125a may act as an indicator of the stemness of the hAMSC, whereas CDKN2D may indicate the begging of early senescence process in a p53-independent mechanism. The genes described in this study will help evaluate the fitness of hAMSC, thus guaranteeing their biological quality for use in regenerative medicine.

Abstract
The aim of this study was to ascertain the variations in the reproductive sex ratio (number of men to number of women) among male professional basketball players in Spain. This retrospective, cross-sectional study is based on a survey conducted in the Spanish professional basketball leagues during the season 2009-2010. A total of 172 professional basketball players completed an anonymous survey. Forty-seven of the respondents had offspring, with a total of 61 children: 70% girls and 30% boys, with a sex ratio value of 0.42. Thirty-three basketball players were Caucasian (CAU), with 44 children, nine boys and 35 girls (sex ratio = 0.26). Fourteen were black, of African heritage (AFR), with 17 children, nine boys and eight girls, (sex ratio = 1.12). Differences (P < 0.01) were found in offspring sex ratio values for all basketball players (sex ratio = 0.42) and for CAU group (sex ratio = 0.26) when compared with the general Spanish population (sex ratio = 1.06). Moreover, a significant seasonal variation was observed in CAU offspring sex ratio during the first quarter compared with the rest of the year (0.66 versus 0.12) (P < 0.03). In conclusion, a significant increase in the sex ratio value in favour of female offspring was observed in the group of CAU professional basketball players.

Abstract
Background Temporomandibular disorder (TMD) is a multifactorial syndrome related to a critical period of human life. TMD has been associated with psychological dysfunctions, oxidative state and sexual dimorphism with coincidental occurrence along the pubertal development. In this work we study the association between TMD and genetic polymorphisms of folate metabolism, neurotransmission, oxidative and hormonal metabolism. Folate metabolism, which depends on genes variations and diet, is directly involved in genetic and epigenetic variations that can influence the changes of last growing period of development in human and the appearance of the TMD. Methods A case-control study was designed to evaluate the impact of genetic polymorphisms above described on TMD. A total of 229 individuals (69% women) were included at the study; 86 were patients with TMD and 143 were healthy control subjects. Subjects underwent to a clinical examination following the guidelines by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Genotyping of 20 Single Nucleotide Polymorphisms (SNPs), divided in two groups, was performed by multiplex minisequencing preceded by multiplex PCR. Other seven genetic polymorphisms different from SNPs (deletions, insertions, tandem repeat, null genotype) were achieved by a multiplex-PCR. A chi-square test was performed to determine the differences in genotype and allelic frequencies between TMD patients and healthy subjects. To estimate TMD risk, in those polymorphisms that shown significant differences, odds ratio (OR) with a 95% of confidence interval were calculated. Results Six of the polymorphisms showed statistical associations with TMD. Four of them are related to enzymes of folates metabolism: Allele G of Serine Hydoxymethyltransferase 1 (SHMT1) rs1979277 (OR = 3.99; 95%CI 1.72, 9.25; p = 0.002), allele G of SHMT1 rs638416 (OR = 2.80; 95%CI 1.51, 5.21; p = 0.013), allele T of Methylentetrahydrofolate Dehydrogenase (MTHFD) rs2236225 (OR = 3.09; 95%CI 1.27, 7.50; p = 0.016) and allele A of Methionine Synthase Reductase (MTRR) rs1801394 (OR = 2.35; 95CI 1.10, 5.00; p = 0.037). An inflammatory oxidative stress enzyme, Gluthatione S-Tranferase Mu-1(GSTM1), null allele (OR = 2.21; 95%CI 1.24, 4.36; p = 0.030) and a neurotransmission receptor, Dopamine Receptor D4 (DRD4), long allele of 48 bp-repeat (OR = 3.62; 95%CI 0.76, 17.26; p = 0.161). Conclusions Some genetic polymorphisms related to folates metabolism, inflammatory oxidative stress, and neurotransmission responses to pain, has been significantly associated to TMD syndrome

Abstract
Background The prevalence of genotypes of the 677C>T polymorphism for the MTHFR gene varies among humans. In previous studies, we found changes in the genotypic frequencies of this polymorphism in populations of different ages, suggesting that this could be caused by an increase in the intake of folate and multivitamins by women during the periconceptional period. The aim was to analyze changes in the allelic frequencies of this polymorphism in a Spanish population, including samples from spontaneous abortions (SA). Methods A total of 1305 subjects born in the 20th century were genotyped for the 677C>T polymorphism using allele specific real-time PCR with Taqman® probes. A section of our population (n = 276) born in 1980–1989 was compared with fetal samples (n = 344) from SA of unknown etiology from the same period. Results An increase in the frequency of the T allele (0.38 vs 0.47; p < 0.001) and of the TT genotype (0.14 vs 0.24; p < 0.001) in subjects born in the last quarter of the century was observed. In the 1980–1989 period, the results show that the frequency of the wild type genotype (CC) is about tenfold lower in the SA samples than in the controls (0.03 vs 0.33; p < 0.001) and that the frequency of the TT genotype increases in the controls (0.19 to 0.27) and in the SA samples (0.20 to 0.33 (p < 0.01)); r = 0.98. Conclusion Selection in favor of the T allele has been detected. This selection could be due to the increased fetal viability in early stages of embryonic development, as is deduced by the increase of mutants in both living and SA populations.

Abstract
Polymorphisms of the genes 5'-10'-methylenetetrahydrofolate reductase (MTHFR, 677CT and 1298AC), methionine synthase (MTR, 2756AC) and methionine synthase reductase (MTRR, 66AC) provoke variations in enzyme activity, which can lead to alterations in the metabolism of folates and in the synthesis of S-adenosyl-methionine (SAM), the most active methyl donor in the body. This could play an important role in carcinogenesis through the degree of DNA methylation and of nucleotide synthesis. In the present study, four polymorphisms were studied, two of the methylenetetrahydrofolate reductase gene, and the other two of methionine synthase and methionine synthase reductase. Our aim was to study the association between prostate carcinoma susceptibility and these polymorphisms. A hospital-based case-control study was conducted in 182 patients (mean age: 70.7+/-7.29 years) with histologically confirmed prostate carcinoma and in 205 control subjects (mean age: 70.3+/-7.82 years) diagnosed with benign prostatic hyperplasia (BPH). Genomic DNA was extracted from peripheral leukocytes. Comparison of the MTHFR CT and TT genotypes in patients and the controls revealed significant differences (0.57 vs 0.38) (OR: 2.19, 95% CI: 1.46-3.30) and (0.06 vs 0.15) (OR: 0.36, 95% CI: 0.17-0.73), respectively. No statistically significant differences were found between patients and controls with respect to the MTHFR 1298AC, the MTR 2756AC and the MTRR 66AC polymorphisms. However, among the patients, the MTR 2756 allele C was related to a high Gleason score. We conclude that the polymorphism MTHFR C677T is clearly related to prostatic carcinogenesis, on the contrary to the other polymorphisms studied, although the MTR 2756 allele C acts as a factor of tumor aggressiveness, this being found in tumors with high carcinogenic potential.

Abstract
BACKGROUND Polymorphisms C677T and A1298C of the MTHFR gene have been implicated in fetal viability. In this study, we determined the allele and genotype frequencies of these polymorphisms in different populations, including spontaneous abortion (SA) fetal tissues, with the objective of evaluating their impact on fetal viability. METHODS 342 samples of fetal tissues, selected from SA occurring during the 1980s, 230 samples from subjects born in the 1980s and a third set of samples from 204 subjects born in the 1950s, were genotyped by using TaqMan probes. RESULTS The wild CC genotype of the C677T polymorphism showed a strong protective effect against abortion (0.03 in SA versus 0.47 in 1950s and 0.43 in 1980s) (P < 0.0001). Genotypes of three mutations in the combinations of polymorphisms for C677T and A1298C showed a very low frequency in the living population; however, the three mutations genotypes were over expressed in the SA group (0.02 in 1950s; 0.03 in 1980s and 0.17 in SA) (P < 0.0001). Samples with four mutations (n = 2) were found only in the SA group. CONCLUSIONS There is no linkage disequilibrium between C667T and A1298C polymorphisms. Fetal viability is directly related to the CC genotype as a protector while the three and four mutation MTHFR genotypes appear to be a determinant on fetal non-viability and SA.

Abstract
BACKGROUND AND OBJECTIVE The influence of homocysteine metabolism on the prognosis of acute coronary syndrome without ST elevation is controversial. PATIENTS AND METHOD Prospective study of 109 patients admitted because of acute coronary syndrome without ST elevation. Basal plasmatic levels of homocysteine and folates were obtained. Clinical features and survival data on follow-up were registered. RESULTS Both two years-free-of-events and total survival were lower in patients with low folate levels (36.5% vs 72.5%, p = 0.02; 48% vs 94%, p < .001). Patients with high homocysteine levels had lower two years-free-of-events survival (57.4% vs 89.1%, p < .01); but no difference in the total survival was observed (86.3% vs 97.3%, p = 0.11). The multivariate analysis showed that low folate levels was an independent predictor of mortality (odds ratio [OR] = 8.33; 95% confidence interval [CI], 1.88-33.33; p < 0.01), and moderate high homocysteine was an independent predictor of events on follow-up (OR = 4.34; 95% CI, 1.47-12.50; p < 0.01). CONCLUSIONS Patients with high homocysteine or low folate levels have a poor prognosis compared with those with normal levels. On the other hand, low folate levels and moderate hyiperhomocysteinemia are independent predictors of bad prognosis in the follow-up.

Abstract
BACKGROUND To test prospectively whether moderate hyperhomocysteinemia and low folate levels could have an influence in the prognosis of 155 patients who presented with an acute coronary syndrome. METHODS AND RESULTS After a mean follow-up of 13.4+/-7.4 months, patients with low folate levels had higher percentages of cardiovascular death and major cardiovascular events (33% vs. 5%, p<0.001; 44% vs. 22%, p<0.05) and patients with high homocysteine levels had a higher percentage of major cardiovascular events (31% vs. 14.5%, p<0.03). Kaplan-Meier survival estimates analysis showed that patients with low folate levels had a significantly higher probability of cardiovascular death and lower free-of-events survival (log rank statistic: 21.17, p<0.001 and 6.59, p=0.01). Patients with high homocysteine levels had a lower free-of-events survival (log rank statistic: 4.95, p=0.02). Different survival multivariate analysis model showed that the presence of low folate levels was an independent predictor of cardiovascular death (hazard ratio 8.85, 95% confidence interval 2.6-29.3, p<0.000) and high homocysteine levels was identified as independent predictor of major cardiovascular events (hazard ratio 2.34, 95% confidence interval 1.07-5.12, p<0.03). CONCLUSIONS Low folate levels and moderate hyperhomocysteinemia were identified as independent predictors of cardiovascular events in the follow-up.

Abstract
INTRODUCTION We analysed the influence of three polymorphisms of the renin-angiotensin system (RAS) (I/D from angiotensin-converting enzyme [ACE], M235T from angiotensinogen gene [ATG] and A1166C from AT1 receptors) on plasma levels of angiotensin I (Ang I), angiotensin II (Ang II) and angiotensin-(1-7) [Ang-(1-7)]. MATERIALS AND METHODS The study population consisted of a homogeneous group of 93 healthy subjects (43 men and 50 women, mean age: 20.67+/-2.75 years). The mean blood pressure (BP) was 126+/-7/76+/-5 (SD) mmHg and the mean body mass index (BMI) was 22.4+/-2.5 kg/m2. Angiotensin peptides were separated by high performance liquid chromatography (HPLC) and quantified by radio immuno assay (RIA). Genotypes were determined by polymerase chain reaction (PCR) and restriction enzyme analysis. RESULTS Mean peptide levels were 92.48+/-102.12 pg/ml for Ang I, 22.35+/-10 pg/ml for Ang II, and 31.65+/-27.46 pg/ml for Ang-(1-7). Men had significantly higher levels of Ang-(1-7) (37.76+/-36.47 pg/ml) than women (26.04+/-13.98 pg/ml) (p<0.05). Among genotypes of each polymorphism, men with the T allele showed higher Ang- (1-7) levels compared with those with the MM genotype (p<0.05). Genotype analysis in women showed that higher Ang I levels were related with the DD genotype. When both genders were compared according to genotype, higher values of Ang-(1-7) levels and its molar ratios were found in men, and there was significantly greater Ang I levels in DD genotypes in women than men (136.72+/-112.43 vs . 65.36+/-46.83 pg/mL). CONCLUSIONS Significant correlations were found between Ang I and Ang II as well as between Ang II and Ang-(1-7) in the different study group distributions. No correlation was found between levels of Ang I and Ang-(1-7). Certain genotypes exert an influence on angiotensin peptide plasma levels which can only be seen when the population is divided according to gender.

Abstract
Various common genotypes of the polymorphism 677 C-->T of the methylenetetrahydrofolate reductase enzyme result in lower activity of the enzyme and in a subsequent increase in homocysteine levels. Many studies have analyzed the connection between this polymorphism and the beginning of coronary artery disease. However, conclusions have been controversial, and evidence of a connection between this polymorphism and the prognosis of coronary artery disease has been poorly evaluated. This prospective study evaluated the prognostic relevance of genotype TT in a cohort of 155 patients admitted to our hospital for treatment of an acute coronary syndrome accompanied by evidence of coronary atherosclerosis on coronary angiography. We found that patients with the genotype TT had higher homocysteine levels than did patients with the CT and CC genotypes (15.72 +/- 6.92 micromol/L vs 12.11 +/- 5.40 micromol/L and 12.01 +/- 4.25 micromol/L, P=0.01). After a mean follow-up of 13.4 +/- 7.4 months, we observed similar rates of major adverse cardiovascular events (CC, 29%; CT, 22%; and TT, 25%) and cardiovascular death (CC, 11%; CT, 7%; and TT, 8%). No difference in cardiovascular-death-free survival (log-rank analysis, 0.81; P=0.66) or event-free survival (log-rank analysis, 0.76; P=0.68) was found. The presence of genotype TT was not an independent predictor of prognosis after multivariate analysis by means of the Cox regression survival model. In conclusion, the presence of the TT genotype of the 677 C-->T polymorphism of the methylenetetrahydrofolate reductase enzyme was not related to prognosis in patients admitted to the hospital after an acute coronary syndrome.

Abstract
Levels of myxovirus resistance protein A (MxA) mRNA were studied for a single nucleotide polymorphism in the promoter region at nucleotide position -88 of the gene to identify individual-specific responses to interferon (IFN)-alpha2 that might predict responsiveness to IFN-alpha therapy. We quantified MxA expression by reverse transcription and real-time polymerase chain reaction in peripheral blood mononuclear cells (PBMC) in vitro, induced by IFN-alpha2, from 22 healthy donors, in relation with G/T polymorphism located in the promoter of the MxA. MxA mRNA was significantly upregulated in all subjects (mean of 53-fold) in response to IFN-alpha2 in vitro (P < 0.01). Comparison of the inducibility of MxA mRNA expression in relation with G/T polymorphism showed a 4.26-fold higher induction of MxA mRNA levels in PBMC from carriers of the mutant allele (GT or TT) than homozygotes with the wild-type allele (GG) (P < 0.001). We propose that expression of the IFN-inducible MxA is affected by a single nucleotide polymorphism in the MxA promoter which can identify an individual response to IFN-alpha2.

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
BACKGROUND Increases in total plasmatic homocysteine (tHcy) represents a risk factor for neural tube defects. We studied the effects of levofolinic acid (l,5-formyl-tetrahydrofolic) on the plasmatic tHcylevels in women of child-bearing age. MATERIALS AND METHOD Healthy women aged 18-35 years (n = 30) received levofolinic acid, 5 mg/day,orally for 30 days. Both tHcy and intraerythrocytic folate levels were measured before treatment (day 0), on days 2, 5, 10 and 30 within the treatment period and on days 30 (day 60) and 60 (day 90) after the treatment was finished. Plasmatic tHcy was measured by fluorescence polarisation immunoassay and intraerythrocyticfolates by chemiluminescent immunoassay. RESULTS Plasmatic tHcy decreased from the second day of treatment onwards (day 0 vs. 2: mean of difference: -1.24 micromol/l; CI 95% = -0.84 to -1.63; p < 0.001). The maximum decline (32.3%) was observed after 30 days (mean of difference = -2.72 micromol/l; CI 95% = -2.20 to -3.24; p < 0.001).After finishing the treatment, the hypohomocysteinic effect persisted up to days 60 (mean of difference = -2.67 micromol/l; CI 95% = -2.07 to -3.26; p < 0.001)and 90 (mean of difference = -1.49 micromol/l; CI 95% = -0.94 to -2.03; p < 0.001). The response was greater when the plasmatic tHcy concentration was >= 9 micromol/l. CONCLUSIONS Levofolinic acid leads to a earlier, intense and persistent drop of the plasmatictHcy levels.

We have studied the role of three polymorphic genes of the renin-angiotensin system (RAS) as independent risk factors for myocardial infarction (MI) and their correlation with three of the major coronary risk factors: serum cholesterol (CH), hypertension (HT) and smoking (SM). A population of 392 men was genotyped for the M235T polymorphism of the angiotensinogen (AGT) gene, the insertion/deletion of the angiotensin-converting enzyme (ACE) and the all66c of the angiotensin-II type 1 receptor (AT1R), by means of polymerase chain reaction (PCR) and restriction enzyme analysis. It was observed that the T allele frequency increased significantly in the MI with HT, CH, and SM subgroup (0.58 vs 0.31) (p<0.01). In contrast, the M allele frequency was higher in the MI without HT, CH, and SM (0.69 vs 0.42) (p<0.01). A strong association between the MM genotype and MI (p<0.001, odds ratio=4.29, confidence interval=1.95-9.42) was found when age-matched MM control subjects were compared to MI individuals with none of the other known major coronary risk factors. Futhermore, subjects with the MM genotype showed a significantly higher plasma renin activity (PRA) profile than those with the TT genotype (p<0.001). It can be concluded that the M allele is an independent risk factor for MI and the T allele modified the risk when other major risk factors are present.

Abstract
We analyzed the evolution with age of the frequencies of the I/D polymorphism of the angiotensin I-converting enzyme (ACE), a1166c of the angiotensin II AT1 receptor (AT1R), M235T of the angiotensinogen (AGT) and A225V of their methylenetetrahydrofolate reductase (MTHFR) gene in a healthy (H) population and the subsequent comparison to age- and sex-matched groups of myocardial infarction (MI) subjects. A total of 472 H subjects were divided into three groups < 30, 30-55 and > 55 years old and 277 individuals with MI into two groups 30-55 and > 55 years old. The evolution with age showed that the AGT M allele (P < 0.001) and the MTHFR V allele (P < 0.05) frequency decreased with age in H men. The comparison between healthy and MI groups showed that the MM genotype frequency increased in MI men > 55 years (OR =4.16; 95% CI; 1.72-10.1) The cc genotype showed a similar behaviour (OR = 3.96; 95% CI; 1.21-12.9). In men, all the combinations with MM genotype presented a high risk, with OR values between 1.10 and 7.22. In women, the cc genotype increased in the MI > 55 group (OR = 6.66; 95% CI; 2.02-21.9). All the combinations with the cc genotype showed OR values between 1.71 and 13.3. The MM genotype in men and cc genotype in men and women, are independent risk factors for MI. We propose that the study of the allele frequency evolution in an H population at different ages is essential to determine risk factors for MI in case-control studies, since data from isolated age-matched groups can be misinterpreted.

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
In the present study, we studied angiotensin II type 1 (AT1) and type 2 (AT2) receptor messengers by quantitative reverse transcriptase-polymerase chain reaction. We examined peripheral blood mononuclear cells from 30 healthy subjects and 50 subjects with primary hypertension, in whom angiotensin I-converting enzyme genotype was determined, before and after 15 days of treatment with different antihypertensive drugs. The medication included a calcium channel antagonist, an angiotensin I-converting enzyme inhibitor, and a beta 1-blocker. We also studied the relationship between AT1 receptor gene expression and biochemical parameters of the renin-angiotensin system. AT1 receptor messenger levels were positively correlated with plasma renin activity in both normotensive and untreated hypertensive subjects. Increases of this messenger and plasma angiotensin II levels were correlated with the D allele in the same individuals. AT1 receptor messenger levels decreased significantly with angiotensin I-converting enzyme inhibitor treatment in subjects with the DD genotype, and a significant decrease was observed in subjects with the II and ID genotypes treated with a calcium antagonist. No changes were observed in mRNA with the beta 1-blocker. We conclude that the AT2 receptor is not expressed in peripheral leukocytes and that AT1 receptor messenger levels vary in relation to angiotensin I-converting enzyme genotype and pharmacological treatment. These results suggest that angiotensin I-converting enzyme genotype may be an important factor when deciding on antihypertensive therapy in individuals with primary hypertension.

Abstract
SUMMARY The levels of human immunodeficiency virus type 1 (HIV-1) RNA have been directly quantitated, after an isolation step, in plasma from patients with primary HIV-1 infection by free solution capillary electrophoresis (FSCE) with ultraviolet detection. HIV-1 RNA was detected and quantified at physiological levels by measuring the absorbance by FSCE. All the patients with primary infection showed concentrations in a range of 1.08-1.71 x 10(8) virions/ml of plasma. No signals were observed in seronegative donors. This procedure represents a practical alternative to other methods to quantify HIV-1 RNA and may be useful in assessing the efficiency of antiretroviral agents, especially during the early stage when other conventional viral markers are often negative.

Abstract
Analysis of the tissue-specific expression of the Q5k gene in the AKR mouse reveals an unusual expression pattern. The Q5k mRNA is present in embryos from day 12, but expression is switched off in most tissues except thymus and testis shortly after birth. Late in pregnancy the gene is again transcribed in females. Analysis at the epitope level, with a Qa-2 specific monoclonal antibody revealed that in most cases the Q5k product is confined to the cytoplasm. These results suggest that Q5k has a most unusual tissue distribution and timing of expression among all the H-2 class I and Q genes so far described.
