Petpides of the hypothalamus.

, 1965
The hypothalamus is that part of the forebrain which forms the floor of the third ventricle in immediate topographical relation with the pituitary gland (1). The limiting boundary of the hypothalamus is ill-defined.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

The long-term impact of obesity in pregnancy on offspring hypothalamic feeding pathways

Royal Society Open Science
An accumulating body of evidence shows that offspring exposure to maternal obesity in the peri-natal period causes an increased risk to develop obesity later in life.

On the importance of including both sexes in animal studies – insights from home‐cage monitoring

Biological Reviews, EarlyView.
ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

Gene Expression of Feed Intake-Regulating Peptides in the Gut–Brain Axis of Laying Hens Housed Under Two Different Egg Production Systems

Animals
Intensive farming methods have improved productivity, but public concerns have arisen regarding the welfare of production animals, particularly laying hens, and consumers demand higher animal welfare standards in all animal production systems. This study

Analysis and Characterization of Kisspeptin and Its Analogues in Serum and Urine Samples by Liquid Chromatography–High‐Resolution Mass Spectrometry for Doping Control Purposes

Drug Testing and Analysis, EarlyView.
Sensitive LC‐HRMS methods were established for the detection of kisspeptin and its analogues in serum and urine, alongside their analytical and metabolic characterization. Stability studies were conducted in serum, plasma, and urine, highlighting the importance of appropriate sample handling for reliable anti‐doping analysis.

Amygdala–hypothalamus–brainstem circuits underlying cardiovascular responses associated with the limits of high-intensity endurance exercise

Frontiers in Physiology
In athletic competitions, athletes continually challenge the limits of human performance. Exercise limitation refers to a state in which fatigue accumulates during prolonged activity, preventing the maintenance of the required power output despite ...

Elimination Profile of Deflazacort and Metabolites in Urine and Plasma Following Oral Administration: Relevance to Sports Drug Testing

Drug Testing and Analysis, EarlyView.
Results confirm that the MRL of 30 ng/mL for 21‐desacetyl‐deflazacort together with a 3‐day washout period is an appropriated strategy to detect oral deflazacort administration in sport competition. ABSTRACT Deflazacort (DEF) is a glucocorticoid prohibited in sports competitions when orally administered.

The role of dopamine release and D2 dopamine receptor in GHRH and somatostatin cells in controlling growth hormone secretion

Frontiers in Endocrinology
IntroductionPituitary growth hormone (GH) secretion is primarily controlled by GH-releasing hormone (GHRH) and somatostatin (SST), peptides produced by hypothalamic neurons. Evidence indicates that dopamine also modulates GH secretion, potentially via D2
