Influence of the TAS2R38 Gene Single Nucleotide Polymorphisms in Metabolism and Anthropometry in Thyroid Dysfunction.

The gene TAS2R38 single nucleotide polymorphisms (SNPs-P49A, A262V and V296I) can condition bitter tasting by PAV (proline-alanine-valine) and non-bitter-tasting by AVI (alanine-valine-isoleucine) homozygosity. We evaluated this polymorphisms association with thyroid function, metabolism and anthropometry parameters determined by: Endpoint analysis (SNPs); DXA (fat mass-%, total fat mass-kg, lean mass-kg); Standard methods (lipid metabolism parameters, HbA1c-%, glycemia-mg/dL, insulinemia-µIU/mL, HOMA-IR, uricemia-mg/dL, calcemia-mg/dL and BMI-kg/m); ELISA (leptinemia-ng/mL); Spectrophotometry (Angiotensin Converting Enzyme activity-UI/L). Statistics: SPSS program; OR [IC95%]; < 0.

Nutritional counselling in adults promoting adherence to the Mediterranean diet as adjuvant in the treatment of major depressive disorder (INDEPT): a randomized open controlled trial study protocol.

Background: Major Depressive Disorder (MDD) is a leading cause of disability worldwide. Approximately one-third of patients with MDD do not respond to treatment, and often exhibit elevated inflammation biomarkers, which are associated with worse prognosis. Previous research has linked healthier dietary patterns, such as the Mediterranean Diet (MedDiet), with a lower risk of MDD and symptoms of depression, potentially due to their anti-inflammatory properties.

Differences in the genotype frequencies of genes related to blood pressure regulation - a comparative study between South-West Europe and Peri-equatorial Africa.

Background: Since the emergence of the genus Homo, hominids have occupied a wide variety of environments, facing different selective pressures.

Objectives: The aim this study is to compare genotype frequencies between South-West Europe and Peri-equatorial Africa in genes potentially modulators of blood pressure.

Methods: The analyzed sample consisted of 325 individuals from Portugal and 226 individuals from Africa (48 from Mozambique and 178 from São Tomé and Príncipe).

Association of myeloperoxidase polymorphism (G463A) with cervix cancer.

Cervical cancer is the fourth most common cancer affecting women worldwide, according to the latest IARC release with 528 000 new cases every year. Infection by high-risk human papillomavirus (HPV) is necessary but not sufficient for progression to cancer. Epithelial tissues, the target of HPV infection, are heavily exposed to reactive oxygen species (ROS).

The role of CYBA (p22phox) and catalase genetic polymorphisms and their possible epistatic interaction in cervical cancer.

Human papillomavirus (HPV) infection is necessary but not a sufficient cause for the development of invasive cervical cancer (ICC). Epithelial tissues, target for HPV, are exposed to reactive oxygen species (ROS) associated with tumor initiation and progression. The NADPH oxidase (NOX) and catalase (CAT) are involved in hydrogen peroxide (H2O2) production and inactivation, respectively.

PP004. The polymorphism C677T of methylenetetrahydrofolate reductase (MTHFR), may increase risk for future higher blood pressure in women with previous hypertension in pregnancy.

Introduction: The MTHFR is a key enzyme in the folate cycle involved in homocysteine remethylation. The T allele of MTHFR C677T polymorphism is associated with lower activity inhibiting the DNA methylation and protecting from oxidative stress.

Objectives: To evaluate the MTHFR genotype-phenotype relationship during and after pregnancy comparing hypertensive with normotensive women.

Decreased erythrocyte activity of methemoglobin and glutathione reductases may explain age-related high blood pressure.

Objectives: Erythrocytes may play an important role in regulating blood pressure as storage sites for nitric oxide (NO). The objective of this work was to determine whether factors related to variations in erythrocyte metabolism associated with NO bioavailability, such as the activity of two enzymes--methemoglobin reductase (MHbR) and glutathione reductase (GSHR)--may help explain age-related increased blood pressure.

Methods: The sample consisted of 468 individuals of both sexes, 237 hypertensive (HT) and 231 normotensive (NT), aged between 18 and 98 years (48.

ACP1 genotype, glutathione reductase activity, and riboflavin uptake affect cardiovascular risk in the obese.

Erythrocyte acid phosphatase (ACP locus 1), also known as low-molecular-weight protein tyrosine phosphatase, has previously been associated to glycemia, dyslipidemia, and obesity. In this study, ACP1 genotype and activity were tested in 318 women aged 19 to 83 (mean, 51.74 +/- 13.

Plant extracts with anti-inflammatory properties--a new approach for characterization of their bioactive compounds and establishment of structure-antioxidant activity relationships.

Geranium robertianum L. (Geraniacea) and Uncaria tomentosa (Willd.) DC.

Activity of two enzymes associated with apoptosis and cell aging in arterial hypertension.

Objective: To study the activity of two enzymes, transmembrane reductase (TMR) and cytosolic low molecular weight protein tyrosine phosphatase (ACP1), in arterial hypertension (HT) in a sample of adults aged over 50 years.

Methods: A sample of 153 adults, 77 with hypertension and 76 normotensive (NT), aged between 50 and 90 years (mean: 71.87 +/- 11.

[Erythrocytic acid phosphatase genetic polymorphism and cardiovascular risk in health children and adolescents].

Objective: To correlate, in a sample of healthy children and adolescents, the activity of the enzyme acid phosphatase (ACP) with its different genetic phenotypes and of these with some cardiovascular risk parameters such as body mass index (BMI), percentage of total fat mass (%TFM), trunk fat (TF), insulin resistance, and the arterial blood pressure (BP).

Design And Methods: The sample was composed of 173 healthy children and adolescents, 96 (55.5%) F and 77 (44.
