Fasting increases neuropeptide Y (NPY) expression, peptide levels and the excitability of NPY-expressing neurons in the hypothalamic arcuate (ARC) nucleus. A subpopulation of ARC-NPY neurons (~ 40%) are glucose-inhibited (GI)-type glucose sensing neurons. Hence, they depolarize in response to decreased glucose. Because fasting enhances NPY neurotransmission, we propose that during fasting GI ne...

ABSTRACT This study aimed evaluate energetic mobilization in tambaqui submitted to fasting, after a one-day refeeding. 120 juveniles were distributed 12 310L polyethylene boxes. Three treatments evaluated: Control (14 days of feeding); Fasting for 14 days; and Refeeding (13 fasting one day feedback). After the experimental period, fish anesthetized with eugenol blood collection serum plasma use...

Several processes contribute to variation in fasting insulin concentration, including fasting glucose, insulin resistance, insulin secretion, and insulin clearance. Our goal was to determine the relative contribution of each of these insulin-related traits, plus anthropometric parameters, to fasting insulin among 470 Mexican Americans. The euglycemic hyperinsulinemic clamp yielded insulin sensi...

Objective Women with gestational diabetes mellitus (GDM) are categorized as at high risk for adverse events during Ramadan fasting. However, this is largely based on clinical opinion. In this study, we shed some light on what happens to glucose levels during Ramadan fasting. Methods This is a prospective observational study. A total of 32 patients with GDM were recruited; 10 patients, treated...

Aims/hypothesis: To assess whether recently discovered genetic loci associated with hyperglycemia also predict long-term changes in glycemic traits. Methods: Sixteen fasting glucose-raising loci were genotyped in middle-aged adults from the GLACIER Study, a population-based prospective cohort study from Northern Sweden. Genotypes were tested for association with baseline fasting and 2-hr postch...

Aim: Fasting plasma glucose (FPG) is the concentration of after an overnight (≤ 8 hours) fast. It diagnostic diabetes mellitus and prediabetes. used in screening other health conditions monitoring treatment diabetes. useful to determine factors that influence FPC for more accurate interpretation test. Procedure: One hundred fifty (150) apparently healthy subjects aged 1 – 80 years were recruite...
