The Effect Of Testosterone On The Spring Migratory Phenotype Of A North American Songbird (Zonotrichia Albicollis), Caitlin L. Vandermeer

In passerines, the endocrine modulators responsible for seasonal changes in migratory behaviour and physiology are unclear. Spring photoperiods alter androgen levels, influencing muscle mass and fat deposition rates to power migration, as well as enhance nocturnal migratory restlessness activity (Zugunruhe). My study compared physiological indicators and migratory restlessness in castrated and intact white-throated sparrows (Zonotrichia albicollis) following photoperiod and hormone manipulation. Nocturnal restlessness activity was highest in migratory intact males or migratory castrated males that received testosterone replacement. Liver mass decreased in all photostimulated migratory groups regardless of testosterone treatment. Likewise, oxidative enzyme activity was unrelated to testosterone, …
Role Of Adenylyl Cyclase S674 In Central And Forearm Vasomotor Control, James Corkal
Role Of Adenylyl Cyclase S674 In Central And Forearm Vasomotor Control, James Corkal

This study examined the cardiac and vasomotor responses to submaximal handgrip exercise and beta-adrenergic control in carriers (n = 6) and non-carriers (n = 4) of a genetic variant of adenylyl cyclase 6 (AC S674). Rhythmic handgrip contractions (1 minute bout; 2 second contraction-relaxation period) were performed at three different intensities (20, 40, and 60% of maximal voluntary contraction force) to test the vasodilatory response to exercise. Additionally, two 5 minute infusions of isoproterenol (0.01 and 0.02 µg·kg-1·min-1 diluted in 5% dextrose) and one 10 minute infusion of propranolol (0.1 mg·kg-1 diluted in 0.9% saline) were …

The purpose of this study was to determine the effect of exercise training alone and in a model of Type 1 Diabetes Mellitus (T1DM), on Heat Shock Protein (HSP) and Nitric Oxide Synthase (NOS) expression in entorhinal adjacent large and small cerebral vessels. Thirty-two rats were randomly allocated to four groups: control sedentary (C), control exercised (CX), diabetic sedentary (D) and diabetic exercised (DX). Exercise training incorporated 5 days/week on a motorized treadmill (27m/min; 6 degree incline; 1 hour) for 10 weeks. Exercise trained groups had significantly greater Hsp70 expression than their respective non-trained groups (p<0.05) and this response was not blunted in T1DM animals. The inducible NOS (iNOS) expression was greater in diabetic sedentary when compared to all other groups (p<0.001). Co-localization of protein with smooth muscle cells illustrates that all HSP and NOS signal content is localized to the smooth muscle area (SMA).
