Contribution of the Adrenal Glands to Postpartum Anestrus in Suckled Cows
… well as in many species. To evaluate the role of adrenal glands in suckling-induced PPA in cattle two experiments were conducted. Exp. 1: Effects on luteinizing hormone (LH) secretion of 3 levels of exogenous corticosteroids; T$\sb1$ = no corticoids, T$\sb2$ = 75 mg of cortisone acetate (CA) + 20 …

Steroid Synthesis Patterns in Cultured Fetal and Neo-Natal Hamster Adrenal Glands
The observation of diurnal biological rhythms was first recorded early in the eighteenth century, but it was 200 years before any detailed investigation of the nature of daily plant and animal rhythms was undertaken (Burning, 1964). | As a more virgorous study of biological rhythms developed, it …

Comparative morphology of the adrenal glands of wild and domesticated mice and the effect of captivity on adrenal structure.
… previous investigators have shown that the adrenal glands are much larger in wild Norway rats than in domesticated Norway rats. In order to determine whether such variations are peculiar to rats, or represent a generalization in nature, the adrenals were examined in other species of rodents. …

System identification of cortisol secretion : characterizing pulsatile dynamics
… stress. Cortisol is released in pulses from the adrenal glands in response to pulses of adreno-corticotropic hormone (ACTH) released from the anterior pituitary; in return, cortisol has a negative feedback effect on ACTH release. Modeling cortisol secretion and the interactions between ACTH and …

Genetically-programmed suicide of adrenergic cells in the mouse leads to severe left ventricular dysfunction, impaired weight gain, and symptoms of neurological dysfunction
… (Pnmt) catalyzes the conversion of noradrenaline to adrenaline and is the last enzyme in the catecholamine biosynthetic pathway. Pnmt serves as a marker for adrenergic cells, and lineage-tracing experiments have identified the embryonic heart and hindbrain region as the first sites of …

Endocrine Effects of Cancer Chemotherapy
… dysfunctions in key endocrine glands, including the hypothalamus-pituitary axis, thyroid, adrenal glands, gonads, and pancreas. Special attention is given to long-term endocrine complications in cancer survivors, particularly in the context of emerging therapies such as immune …

Some physiological characteristics of wild, caged-stressed, and shock-comatose gray squirrels
… in the overall homeostatic processes. The adrenal glands from the confined-shocked individuals were approximately 6-8 mg heavier than either the normal or confined-stressed animals. Packed-cell-volumes averaged from 31-36% higher than normal in both the confined-stressed and …

The nutritonal ecology of meadow voles (Microtus pennsylvanicus) under differing environmental conditions
… small intestine, caecum, large intestine, adrenal glands, liver, and kidneys was evaluated. Data was analyzed by ANOVA using the SAS system. Meadow voles increased food intake but decreased turnover time and digestive efficiency under low ambient temperature condition, short daylength, …

Von Hippel-Lindau Syndrome: Characterization of a Potentially Novel VEGF-A Isoform and Elucidation of Molecular and Vascular Mechanisms of Observed Phenotypic Changes
… to cancer in neurological tissues, the kidneys, adrenal glands, pancreas, and liver, including neurological hemangioblastoma (HB), pheochromocytoma (PCC), pancreatic neuroendocrine tumors (PNET), pancreatic and renal cysts, and clear cell renal cell carcinoma (ccRCC). The disease process follows …

A study of the factors controlling embryo transport in the oviduct of the mouse.
… in isthmic transport. Removal of ovaries and adrenal glands resulted in a retardation of tubal transport which can be reversed by progesterone administration and measurement of serum progesterone levels indicates that progestogenic activity is required for normal tubal transport. …

Adipose-Derived Stromal Cells Contribute To Spinal Cord Repair But Are Not Neural-Crest Derived Stem Cells
… and glia of the peripheral nervous system, adrenal glands, chondrocytes and osteocytes of the head and neck, smooth muscle cells of the cardiac outflow tract, and melanocytes among others. Given the reported ability of neural crest-derived cells and ADAS cells to give rise to bone, …

Isolation, identification and characterization of vasoactive substances from endothelial cells, platelets and mononuclear leukocytes
… from different tissues and body fluids like adrenal glands, heart and platelets and plasma by using these innovative chromatographic and mass-spectrometric methods. Moreover, a potent vasoconstrictive dinucleoside polyphosphate with a purine and pyrimidine base was isolated from supernatants …

The Roles of Inflammation, Oxidative Stress, and Neurotransmitters in an Animal Model of Post-Traumatic Stress Disorder
… in the brain, hypothalamic-pituitary-adrenal (HPA) axis, and immune system that may be partially responsible. Many chronic conditions such as hypertension, heart failure, and metabolic syndrome perpetuate in a state of increased inflammation and oxidative stress, exacerbating their …

Long-Term Hypoxia Regulates Cortisol Biosynthesis in the Ovine Fetal Adrenal Cortex
Previous studies demonstrated enhanced fetal adrenal cortisol biosynthesis following exposure to long-term hypoxia (LTH). The studies presented here were designed to determine the mechanism(s) regulating this important adaptive endocrine response. Ewes were maintained at high altitude (3,820 m) …

The role of Men1 in pituitary gland tumourigenesis
… the hypothalamus and from peripheral endocrine glands and responds to changing physiological needs by secreting a series of hormones that regulate the activity of various endocrine glands as well as acting directly on many tissues. Tumours of the pituitary gland are relatively frequent possibly …

Measuring steroids from dried blood spots using tandem mass spectrometry to diagnose congenital adrenal hyperplasia
Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders that occur due to defects in the steroidogenesis pathway within the adrenal glands. CAH is characterized by numerous clinical manifestations resulting from dysregulation of various enzymes in the steroidogenesis …

Transcriptome analysis of the hypothalamic-pituitary-adrenal axis in the experimentally domesticated fox
… stress response, or hypothalamic-pituitary-adrenal (HPA) axis, has been associated with different personality traits and coping styles in humans and animals, while its dysregulation has been implicated in psychological disorders. The molecular basis of HPA axis regulation, however, is not …

Maternal separation in the rat : long-term effects of early life events on emotionality, drug response and neurobiology
… monoamines, corticosterone levels and weight of adrenal and thymus glands were measured. When separating pups as intact litters kept in incubators, there were mainly no alterations in emotionality, amphetamine-induced locomotor activity, opioid peptide levels or in plasma corticosterone levels in …
