The decrease in growth hormone (GH) response after repeated stimulation with GH-Releasing hormone is partly caused by an elevation of somatostatin tonus. [PDF]

, 1996
Repeated injection of GHRH leads to a decrease in the GH response in normal subjects. Arginine (Arg) stimulates GH secretion by suppression of hypothalamic somatostatin.

Metabolic Adaptations to Weight Loss in Obese Senior Dogs: Effects on Energy Expenditure, Protein Turnover, and Voluntary Physical Activity

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Implications of obesity and weight loss (WL) for energy and protein metabolism are not fully understood, particularly in senior dogs. This study evaluated changes in body composition, energy expenditure (EE), protein turnover (PT), and voluntary physical activity (VPA) in senior dogs in maintenance and after 10% and 20% WL.

The Influence of Different Light Spectra on Broiler Chicken Endocrine Systems and Productivity

Animals
In birds, light can penetrate the cranial bones and reach deep brain regions, where non-visual photoreceptors, especially in the hypothalamus, detect spectral and photoperiodic cues.

Endogenous thyrotropin-releasing hormone in the anterior pituitary: sites of activity as identified by immunocytochemical staining.

, 1978
Thyrotropin-releasing hormone (TRH) immunoreactivity was localized in the rat anterior pituitary with rabbit anti-TRH sera and the unlabeled antibody peroxidase-antiperoxidase complex (PAP) technique.

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Intrinsic pH chemosensitivity of acutely dissociated medullary serotonergic and retrotrapezoid neurones

The Journal of Physiology, EarlyView.
Abstract figure legend Central respiratory chemoreceptors (CRCs) are critical for maintaining normal systemic levels of pH and PCO2. A CRC must respond to pH via intrinsic mechanisms. Here we quantified intrinsic chemosensitivity of medullary 5‐HT neurones and retrotrapezoid nucleus (RTN) neurones using acute dissociation.

Primary Hypothyroidism With Markedly High Prolactin

Frontiers in Endocrinology, 2016
Secondary Pituitary enlargement due to primary hypothyroidism is not a common manifestation. The loss of thyroxin feedback inhibition in primary hypothyroidism causes overproduction of thyroid-releasing hormone (TRH), which results in secondary pituitary

Luteinizing Hormone-Releasing Hormone and Thyrotropin-Releasing Hormone Induction of Female Sexual Receptivity in the Lizard, Anolis carolinensis

, 1980
Both luteinizing hormone-releasing hormone (LHRH) and thyrotropin-releasing hormone (TRH) induce sexual receptivity in ovariectomized, estrogen-primed female lizards (Anolis carolinensis).

Cardiovascular Autonomic Neuropathy in Charcot–Marie–Tooth Disease: A Genotype‐Stratified Study of PMP22 Duplication and GJB1 Mutation Carriers

Journal of the Peripheral Nervous System, Volume 31, Issue 4, December 2026.
ABSTRACT Background and Aims Data on cardiovascular autonomic neuropathy (CAN) are sparse in Charcot–Marie–Tooth disease. We aimed to determine the prevalence of CAN in CMT1A and CMTX1 and its associations with neuropathy severity and heart rate variability (HRV), compared with age‐ and sex‐matched controls. Methods Thirty‐six CMT1A, 24 CMTX1 patients,
