introduction: scorpion venom is a source of bioactive peptides, and some antimicrobial peptides (amps) have been found in the venom gland of scorpions. therefore, the discovery of new anti-infective agents is an essential need to overcome the problem of antibiotic resistance of clinical isolates. here, we describe three new cationic amps, including meuvap-6, meuap-18-1, and meupep34 from the ve...

background: the influence of hashimoto’s thyroiditis (ht) with subclinical hypothyroidism or euthyroid status on the alteration of glucagon-like peptide (glp)-1 and glp-2 levels remains uncertain. materials and methods: twenty-four untreated ht patients with subclinical hypothyroidism, 24 euthyroid ht patients, and 24 age- and gender-matched controls were enrolled in the study. the levels of gl...

The short in vivo half-life of GLP-1 prevents it from being used clinically. This short half-life occurs because GLP-1 is rapidly degraded by dipeptidyl peptidases such as DPP-IV. To overcome this obstacle, a GLP-1/Fc was constructed and evaluated to determine if it was degraded by DPP-IV and in serum. When the degradation of GLP-1/Fc by human DPP-IV and rabbit serum was compared with that of G...

To determine whether fasting and meal-induced appetite-regulating hormones are altered during lactation and associated with body weight retention after childbearing, we studied 24 exclusively breastfeeding women (BMI = 25.2 ± 3.6 kg/m(2)) at 4-5 weeks postpartum and 20 never-pregnant controls (BMI = 24.0 ± 3.1 kg/m(2)). Ghrelin, PYY, GLP-1, and appetite ratings were measured before/and 150 minu...

The presence of a circulating factor affecting gut growth can be surmised from the findings in gut isolated from the main food stream and not under direct nutritional influence. Thus when a Thiry Vella fistula is constructed and the crypt cell production rate counted in the fistula it can be shown to correlate with the degree of resection of the main bowel left in continuity. The only hormones ...

We compared the acute response of anorexigenic signals (total PYY and GLP-1) in response to submaximal and supramaximal exercise. Nine females completed three sessions: (1) moderate-intensity continuous training (MICT; 30 min; 65%  VO2max); (2) sprint interval training (SIT; 6 × 30 sec "all-out" cycling sprints with 4 min recovery); or (3) control (CTRL; no exercise). PYY and GLP-1 were measure...

This review analyses a recent advance in diabetes pharmacotherapeutics: the combination of insulin and glucagon-like peptide 1 receptor agonists (GLP 1 RA). It describes the rationale for such a combination, and discusses the impact of such therapy on glycaemic control. The paper also assesses other benefits of the combination, and provides a practical framework for pragmatic, rational use of t...
