Due to phoenixin's role in restraint stress and glucocorticoid stress, as well its recently shown effects on the inflammasome, we aimed investigate of lipopolysaccharide (LPS)-induced inflammatory activity brain nuclei-expressing phoenixin. Male Sprague Dawley rats (n = 6/group) were intraperitoneally injected with either LPS or control (saline). Brains processed for c-Fos phoenixin immunohistochemistry resulting slides evaluated using ImageJ software. was counted densitometry. significantly...

Nesfatin-1 is a well-established anorexigenic peptide. Recent studies indicated an association between nesfatin-1 and anxiety/depression-like behavior. However, it unclear whether this effect retained in obesity. The aim was to investigate the of nesfatin-130-59—the active core nesfatin-1—on anxiety depression-like behavior normal weight (NW) diet-induced (DIO) obese rats. Male rats were intracerebroventricularly (ICV) cannulated received nesfatin-130-59 (0.1, 0.3, or 0.9 nmol/rat) vehicle...

The prevalence and incidence of depressive disorders are rising worldwide, affecting about 322 million individuals, underlining the need for behavioral studies in animal models. In this protocol, to study depression-like anhedonic behavior rats, established sucrose preference novelty-induced hypophagia tests combined with an automated food liquid intake monitoring system. Prior testing, paradigm, male rats trained at least 2 days consume a solution addition tap water. During test, again...

Phoenixin-14 is a recently discovered peptide regulating appetite. Interestingly, it expressed in the gastrointestinal tract; however, its supposed receptor, GPR173, predominantly found hypothalamic areas. To date, unknown how peripherally secreted phoenixin-14 able to reach centrally located receptor. investigate whether phoenixin pass blood-brain barrier, we used an vitro mono-culture barrier (BBB) model consisting of brain capillary-like endothelial cells derived from human...

Abstract Background Gastric electrical stimulation (GES) is an effective therapy in medically refractory chronic nausea and vomiting. GES assumed to be a contraindication for pregnancy. We examined the safety of during pregnancy its clinical impact on vomiting symptoms. Methods A retrospective study was performed two tertiary centers including all female patients childbearing age implanted with GES. Patients without while were asked about their desire concerns who pregnant interviewed course...
