Summary: Pituitary hormone axes play a key role in regulating glucose metabolism and can impact insulin secretion. Patients with pituitary adenomas may experience impaired glucose tolerance, but correcting pituitary dysfunction can often lead to improved glucose homeostasis.

Summary: So far, neuroendocrine studies conducted in schizophrenic patients have yielded conflicting results due to various influencing factors, population heterogeneity, lack of test standardization, and previous treatments effects. Apomorphine (APO) has been widely used in evaluating dopaminergic (DA) function by indirectly assessing the functionality of DA receptors at the hypothalamic-pituitary level. This review provides an update on the applications of the APO test in schizophrenia in clinical, pathophysiological, and therapeutic fields.

Summary: Exercise represents a physiological stimulus that initiates hormonal responses, with GH showing the highest increase among analyzed hormones. Puberty was found to significantly enhance GH secretion in response to exercise, while cortisol and prolactin responses did not differ based on sex or pubertal status.

Summary: The etiopathogenesis of fibromyalgia (FM) and chronic fatigue syndrome (CFS) is not yet understood. A new hypothesis suggests that moderate or intermittent intracranial hypertension may be involved in the development of FM and CFS. This study explored the similarities between primary empty sella (ES) and FM or CFS in hormonal changes and symptoms, linking them to cerebrospinal fluid pressure dysregulation. The findings support the involvement of increased cerebrospinal fluid pressure in the development of FM and CFS.

Summary: This study investigated the early evolution and function of the growth hormone (GH)/prolactin (PRL) family using a representative of one of the oldest vertebrate lineages. A second member of the GH/PRL family, prolactin-like (PRL-L), was identified in the sea lamprey. The findings provide insights into the origin and divergence of GH/PRL family genes in early vertebrates. The lamprey PRL-L plays a role in osmoregulation and is comparable to the function of PRLs in jawed vertebrates.

Summary: This study investigated the effect of aquacultural stressors on the pituitary-testis axis in a breeding cichlid fish. The results showed that exposure to stressors led to a decrease in spermatid production, suppression of LH synthesis, and decreased androgen receptor expression in the testis. The findings suggest that chronic aquacultural stressors can disrupt the reproductive process in fish.

Summary: The metabolic, circadian, sleep, and reproductive systems are interconnected and regulated, but the understanding of their mechanism is limited. This study disrupted the circadian timing system in pregnant nonlactating cows and found that body temperature and hormone concentrations were affected, especially in relation to gestation.

Summary: The study provides a qualitative and quantitative description of polypeptide hormone secreting cellular components of the Gottingen minipig adenohypophysis using immunohistochemistry and stereology. The normal minipig adenohypophysis contains a different number of GH, PRL, and ACTH producing cells, with distinct distribution patterns. The relative proportions of hormone producing cells are similar to those in humans, primates, and rodents, but the distribution varies among species.

Summary: This study aimed to investigate the potential use of intranasal glucagon as a stimulus test for the evaluation of pituitary function. The results showed that intranasal glucagon administration is not effective for pituitary secretion and can lead to hypokalemia as a complication.

Summary: Tilapia is a widely cultivated cichlid species and the GIFT strain is important for the international market. This study investigated the acute toxicity of Ammonia in GIFT Tilapia strains and found that smaller fish and higher stocking densities were more susceptible to NH3 concentrations. The toxic effects of NH3 on the gills were identified through histopathological analysis. The results suggest that GIFT Tilapia has a high tolerance to the toxic effects of Ammonia.

Summary: The endocrine system plays a central role in lactation, with hormones like prolactin, growth hormone, and estrogen directly influencing milk secretion and mammary gland development through regulation by the hypothalamus-pituitary axis.

Summary: The research reveals that pyraclostrobin mainly enters fish through the gills, with the most severe toxic effects observed in the gills, potentially causing oxidative damage, changes in ventilation frequency, and other reactions. This indicates that the gills are important target organs for pyraclostrobin toxicity.

Summary: Increasing industrial and agricultural activities have led to an increase in pollutant discharges, affecting the growth and reproductive development of vertebrates, particularly fish, through endocrine-disrupting chemicals (EDCs). Fish serve as sentinel species due to their early susceptibility to waterborne EDCs, with studies focusing on acute or chronic exposure at different developmental stages. Various experimental methods are employed to characterize the effects of prevalent EDCs and potential carriers like microplastics, including in vivo, in vitro, and computational approaches.

Summary: Euryhaline fishes maintain hydromineral balance in various salinities by utilizing multiple osmoregulatory organs, including the gill, gastrointestinal tract, skin, kidney, and urinary bladder. This study found that Na+/Cl- cotransporter 1 (Ncc1) and Clc family Cl- channel 2c (Clc2c) mRNA levels were significantly higher in freshwater-acclimated tilapia, suggesting their contribution to the functional plasticity of the kidney and urinary bladder in response to changing environmental salinity.

Summary: The study indicates that thyroid hormones play a crucial role in the adaptation of Mozambique tilapia to freshwater environments by interacting with branchial deiodinases to modulate their activities. External osmotic conditions do not directly affect the gene expression of branchial deiodinases, while systemic signals may stimulate thyroid hormone metabolism.

Summary: Prolactin cells in Mozambique tilapia rapidly respond to temperature and osmotic stimuli by releasing different isoforms of prolactin. An increase in temperature stimulates the release of prolactin and causes an increase in cell volume. The mRNA expression related to osmotic stimuli is affected by temperature changes as well.

Summary: In estuarine environments, euryhaline fish maintain internal osmolality despite changes in environmental salinity. The neuroendocrine system, specifically the hypothalamic-pituitary-interrenal (HPI) axis, plays a crucial role in this process by releasing cortisol. Cortisol acts as both a mineralocorticoid and glucocorticoid, regulating osmoregulation and metabolism. This study investigated the responses of cortisol, pituitary pomc expression, and corticosteroid receptors in the gill and liver of Mozambique tilapia under different salinity challenges. The results suggest that the HPI-axis is important for salinity acclimation in changing environments.
