AI Article Synopsis
- Caerulein infusion (100 ng/kg/h for 1 hour) did not affect the basal levels of prolactin and thyroid-stimulating hormone (TSH) in healthy male volunteers.
- The response of prolactin to TRH stimulation significantly increased during caerulein infusion, while the TSH response decreased.
- These findings indicate that caerulein, a peptide similar to cholecystokinin, may play a role in regulating pituitary secretion of prolactin and TSH in humans.
Article Abstract
The effect of caerulein (100 ng/kg/h X 1 h) on basal as well as on thyrotropin-releasing hormone (TRH)-stimulated prolactin and thyroid-stimulating hormone (TSH) secretion was studied in healthy male volunteers. The peptide did not change the basal levels of prolactin and TSH. However, during the infusion of caerulein, prolactin response to TRH was significantly increased whereas the TSH response was decreased. These data, showing an action of caerulein (a frog peptide which mimics the biological actions of cholecystokinin) on prolactin and TSH release, suggest that cholecystokinin may be involved in the physiological control of human pituitary secretion.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, and, with only 15-20% of HCC patients being suitable for potentially curative treatments, the vast majority of patients with HCC ultimately require systemic therapy. For decades, the choice of effective systemic therapy for HCC remained sparse. In recent years, after the combination of atezolizumab and bevacizumab demonstrated superior overall survival over the first-line standard, sorafenib, there has been a major therapeutic paradigm shift to immunotherapy-based regimens for HCC.

Since the early discovery of QRFP43, intensive research has been primarily focused on its role in the modulation of food intake. As is widely recognised, the regulation of the body's energy status is a highly complex process involving numerous systems, hormones and neurotransmitters. Among the most important regulators of energy status, alongside the satiety and hunger centre located in the hypothalamus, is the HPT axis, which directly and indirectly affects the regulation of metabolism in all cells of the body.

Context: Subclinical hypothyroidism (SCH) is characterized by elevated thyroid-stimulating hormone (TSH) levels and normal free thyroxine (fT4) levels. In upper normal TSH levels, thyrotropin-releasing hormone (TRH) stimulation test proved to be useful in identifying an exaggerated TSH response.
Objective: We aimed to evaluate the incidence and predictive ability of basal TSH, anti-thyroid peroxidase antibodies (TPOAb), and anti-thyroglobulin antibodies (TgAb) for exaggerated TRH stimulation test in SCH.

The Pearl River Delta (PRD) region in southern China is a densely populated area and a hotspot for Vibrio parahaemolyticus infections. However, systematic research on this pathogen, particularly comparing clinical and environmental strains, remains limited. This study analyzed the molecular epidemiology and antimicrobial resistance of 200 V.

The hypothalamus secretes the thyroid-releasing hormone (TRH) that induces the pituitary gland to release the thyroid-stimulating hormone (TSH) which stimulates thyroid follicular cells to release the thyroid hormones (THs), thyroxine (T4), and triiodothyronine (T3). The process of synthesizing T3 and T4 hormones involves various enzymatic steps, starting with the iodination of L-tyrosine residues present in the protein thyroglobulin. Thyroid hormones are released into the bloodstream, where they bind to thyroid hormone distributor proteins (THDPs) which transport them in the circulation.
