Evidence from studies in goats1, sheep2 and mice3 suggests that the kisspeptin cells of the arcuate nucleus generate the signal that causes the pulsatile secretion of GnRH. This effect may be due to action of kisspeptin on GnRH terminals in the median eminence3,4. We conducted studies on sheep to test the hypothesis that kisspeptin cells of the arcuate nucleus (ARC) and/or the glutamate cells of the hypothalamus pulses of GnRH secret...

Introduction: Eating habits may contribute to longevity. Consumption of red meat, source of saturated fatty acids and cholesterol may be associated with increased risks of diabetes, cardiovascular disease (CVD), and mortality risk.Methods: We studied 521 subjects, both genders, 253 centenarians (CENT) (100.26±1.98 age) and 268 controls (67.51±3.25 age), both low (LCR) and high cardiovascular risk (HCR), calculated based on QRISK®2-2016. An...

Introduction: Fat-free mass has a functional significance in aging. The objective of this study was to evaluate the prevalence of underweight in a Portuguese population of centenarians and their relationship with dehydration or sarcopenia.Methods/design: Anthropometric data were obtained using standard procedures from 252 centenarians (100.26±1.99 years), 77.8% women (W). Body composition was assessed by tetrapolar bioimpedance. It was considered de...

Background and objectivesTAS2R38 is a bitter taste gene that can influence food consumption depending on its single nucleotide polymorphisms (SNPs) leading to aminoacid substitutions in the receptor protein P49A (proline/alanine), A262V (alanine/valine) e V296I (valine/isoleucine). Subjects with at least one PAV (proline-alanine-valine) copy are bitter tasters, while AVI homozygotes are non-tasters. Other variants have intermediate bitter tasting: AAV&#6...
