1. Serum irisin and apelin levels and markers of atherosclerosis in patients with subclinical hypothyroidism
ABSTRACT Objective: In this study, we aimed to evaluate serum irisin and apelin levels in patients with subclinical hypothyroidism (SCH) when they were subclinical hypothyroid and become euthyroid after levothyroxine therapy and association of these adipokines with markers of atherosclerosis such as serum homocysteine levels and carotid intima-media thickne

2. Helicobacter pylori Infection is a Significant Factor Risk for Hyperhomocysteinemia in the Patients with Coronary Artery Disease
ABSTRACT This work aimed to determine whether seropositivity to Helicobacter pylori infection was an independent risk factor for hyperhomocysteinemia patients with cardiovascular disease. The H. pylori IgG, IgA and homocystein levels in 96 patients with cardiovascular disease and 64 participants free of cardiovascular disease as control subjects were determi

3. IL-6 and TNF-α serum levels are associated with early death in community-acquired pneumonia patients
Community-acquired pneumonia (CAP) is amongst the leading causes of death worldwide. As inflammatory markers, cytokines can predict outcomes, if interpreted together with clinical data and scoring systems such as CURB-65, CRB, and Acute Physiology and Chronic Health Evaluation II (APACHE II). The aim of this study was to determine the impact of inflammatory

4. Evaluation of cardiovascular disease risk factors in patients with mycosis fungoides
BACKGROUND: Mycosis fungoides, the most common subtype of cutaneous T-cell lymphoma, is more common in patients aged 45-55. OBJECTIVE: Cardiovascular risk factors have been investigated in several skin diseases. However, the relation bet

5. Síndrome de Down e polimorfismos em genes envolvidos no metabolismo do folato.
A síndrome de Down (SD) é uma doença genética complexa resultante, principalmente, da presença de três cópias do cromossomo 21. É a cromossomopatia humana mais frequente e, na maioria dos casos (cerca de 95%), decorrente da não disjunção cromossômica materna, ocorridas durante a meiose I. Recentes estudos sugerem que a etiologia do risco materno

6. Preditores dietéticos das concentrações séricas ou plasmáticas de homocisteína, ácido fólico, vitaminas B12 e B6 em mulheres / Dietary predictors of serum or plasma concentrations of homocystein, folic acid, vitamins B12 and B6 in low-income women in São Paulo, Brazil.
Objective To examine whether measurements of dietary intakes, obtained with a validated quantitative food frequency questionnaire (FFQ), correlated with serum or plasma levels of folic acid, vitamins B12 and B6 and homocystein (hcy) measured in low-income women living in São Paulo, Brazil. Population and methods We analyzed dietary data from 1434 women aged

7. Investigation of thrombophilias in high risk pregnant patients for preterm birth. / Investigação de trombofilias em gestantes de risco para o parto prematuro
Introduction: The spontaneous preterm birth is a multifactorial disease and its etiology remains unknown in 40% of the time. In this study, we investigated the acquired and inherited thrombophilias in high risk pregnant patients to the spontaneous preterm birth and related to the incidence of prematurity in the current pregnancy. Methods: In this prospective

8. Inhibition of leucine transport in Saccharomyces by S-adenosylmethionine.
S-Adenoxyl-L-methionine (SAM) inhibited leucine transport in Saccharomyces cerevisiae. By using a mutant defective in the active transport of SAM, we demonstrated that the inhibitory effect was exerted at an extracellular site. Cells preincubated wtih SAM for 120 min became refractory to its inhibitory effect, which was not a result of either the active tran

9. Studies on N5-methyltetrahydrofolate-homocystein methyltransferase in normal and leukemia leukocytes.
A cobalamin-dependent N5-methyltetra-hydrofolate-homocysteine methyltransferase (methyl-transferase) was demonstrated in unfractioned extracts of human normal and leukemia leukocytes. Activity was substantially reduced in the absence of an added cobalamin derivative. Presumably, this residual activity reflects the endogeneous level of holoenzyme. Enzyme acti

10. Resistance of an adenosine kinase-deficient human lymphoblastoid cell line to effects of deoxyadenosine on growth, S-adenosylhomocysteine hydrolase inactivation, and dATP accumulation.
Accumulation of dATP derived from 2'-deoxyadenosine (dAdo), causing inhibition of ribonucleotide reductase and depletion of the other deoxynucleotide substrates required for DNA synthesis, has been suggested as the cause of the lymphopenia and immune defect in inheritable deficiency of adenosine deaminase (adenosine aminohydrolase, EC 3.5.4.4). dAdo also ina
