Five sublacustrine thermal spring locations from 1 to 109 m water depth in Yellowstone Lake were surveyed by 16S ribosomal RNA gene sequencing in relation to their chemical composition and dark CO(2) fixation rates. They harbor distinct chemosynthetic bacterial communities, depending on temperature (16-110°C) and electron donor supply (H(2)S <1 to >100 μM;(More)
BACKGROUND Smoking may have a beneficial effect on either schizophrenic symptoms or antipsychotic side-effects, but studies are hampered by the lack of control of confounding factors. AIMS To explore the self-medication hypothesis in a large sample of stable out-patients with schizophrenia. METHOD Symptoms, assessed with the Positive and Negative(More)
Obesity is linked to a low-level chronic inflammatory state that may contribute to the development of associated metabolic complications. Retinol-binding protein 4 (RBP4) is an adipokine associated with parameters of obesity including insulin resistance indices, body mass index, waist circumference, lipid profile, and recently, with circulating inflammatory(More)
BACKGROUND Vaspin and omentin are recently described molecules that belong to the adipokine family and seem to be related to metabolic risk factors. The objectives of this study were twofold: to evaluate vaspin and omentin circulating levels and mRNA expression in subcutaneous and visceral adipose tissues in non-diabetic morbidly obese women; and to assess(More)
In a prior US study, schizophrenia vulnerability was associated with higher risk of initiating daily smoking after 20 years of age. A survival analysis of onset age of daily smoking compared 290 controls with 250 consecutive DSM-IV schizophrenia patients from outpatient facilities at an urban catchment area in Spain. After controlling for gender and(More)
Lipid accumulation in the human liver seems to be a crucial mechanism in the pathogenesis and the progression of non-alcoholic fatty liver disease (NAFLD). We aimed to evaluate gene expression of different fatty acid (FA) metabolism-related genes in morbidly obese (MO) women with NAFLD. Liver expression of key genes related to de novo FA synthesis (LXRα,(More)
BACKGROUND The self-medication hypothesis proposes that schizophrenia patients smoke to decrease their schizophrenia symptoms or antipsychotic side effects, but they usually start smoking before their illness and heavy smoking is not consistently associated with fewer symptoms or side effects. A narrow version of the self-medication hypothesis, heavy(More)
Several studies suggest that caffeine intake is high in patients with schizophrenia and a few of them suggest that caffeine may contribute to schizophrenia symptomatology. None of these studies control for the effect of tobacco smoking, which is associated with induction of caffeine metabolism. Therefore, the high amount of caffeine intake among patients(More)
Background: Tumor necrosis factor alpha (TNF-α) is thought to be involved in the various immunogenetic events that influence HIV-1 infection. Methods: We aimed to determine whether carriage of the TNF-α-238G>A,-308G>A and-863 C>A gene promoter single nucleotide polymorphisms (SNP) and the CCR5Δ32 variant allele influence the risk of HIV-1 infection and(More)
