Early life stress has enduring effects on behavior and physiology. However, the effects on hormones and stress physiology remain poorly understood. In the present study, parents of zebra finches of both sexes were exposed to an increased foraging paradigm from 3 to 33days post hatching. Plasma and brains were collected from chicks at 3 developmental time points: post hatching days 25, 60 and adulthood. Plasma was assayed for testosterone (T), estradiol (E2), and corticosterone (CORT). The paraventricular nucleus of the hypothalamus was assessed for corticotrophin releasing factor (CRH) and glucocorticoid receptor (GR) expression...

REVIEW
Ronak A Gor, Sean P Elliott
Surgery for patients with neurogenic urinary tract dysfunction (nLUTD) is indicated when medical therapy fails, to correct conditions affecting patient safety, or when surgery can enhance the quality of life better than nonoperative management. Examples include failure of maximal medical therapy, inability to perform or aversion to clean intermittent catheterization, refractory incontinence, and complications from chronic, indwelling catheters. Adults with nLUTD have competing risk factors, including previous operations, obesity, poor nutritional status, complex living arrangements, impaired dexterity/paralysis, and impaired executive and cognitive function...

Marcos Martin-Rincon, David Morales-Alamo, Jose A L Calbet
Although exercise exerts multiple beneficial health effects, it may also damage cellular structures. Damaged elements are continuously degraded and its constituents recycled to produce renovated structures through a process called autophagy, which is essential for the adaptation to training. Autophagy is particularly active in skeletal muscle, where it can be evaluated by using specific molecular markers of activation (unc-51-like kinase 1 (ULK1) phosphorylation) and specific proteins indicating increased autophagosome content (increased total LC3, LC3-II, LC3-II/LC3-I ratio)...

Physical exercise is a stress that modulates a plethora of cellular mechanisms to promote morphological and metabolic adaptations. Substantial efforts have been made to better understand the modulation of pathways involved in cell plasticity during exercise, but human explorations may be limited because invasive procedures are often required. In recent years, minimally invasive methods for the analysis of microRNAs (miRNAs) modulation in response to exercise have been developed. miRNAs are small molecules that belong to a family of non-coding RNAs...
