Temperature is a crucial environmental factor that significantly impacts the growth, development, metabolism, and physiological functions of fish. To study the effects of low-temperature on the gonadal development of silver pomfret (Pampus argenteus), a cold period by gradually lowering the water temperature from 18°C to 9°C was simulated. The results showed that hsp70, hsp90a, and hsp90b were widely expressed in the tissues of P. argenteus, with hsp70 primarily expressed in the pituitary, hsp90a and hsp90b mainly expressed in the lateral. The hsps were involved in the development process of P. argenteus from 1 to 27 days post-hatching (dph). The expression levels of hsp70 and hsp90b were highest at 17 dph, while the levels of hsp90a were at 25 dph. Under the condition of 9°C, regressed oocyte were observed in the ovaries, the oocyte diameter significantly decreased, and the ovaries degenerated 100% after low-temperature stress. The expression levels of hsps in the ovaries were significantly higher than in the control group, while the expression levels in the testes were significantly lower than in the control group. Taken together, hsps may regulate the ovarian degeneration under low-temperature stress. Male fish rapidly completed meiosis and maintained the testes in the prophase of meiosis to resist the low-temperature stress.

Background: Crohn's disease and irritable bowel syndrome may both cause abdominal pain and diarrhea. Irritable bowel syndrome not only is an important differential diagnosis for Crohn's disease but also occurs in one out of three patients with Crohn's disease in remission in parallel. If not adequately diagnosed and treated, additional functional symptoms such as fatigue and/or muscle pain may develop, indicating a more severe course.

Background: Calmodulin-binding transcription activator (CAMTA) proteins play significant roles in signal transduction, growth and development, as well as abiotic stress responses, in plants. Understanding their involvement in the low-temperature stress response of teak is vital for revealing cold resistance mechanisms.
Results: Through bioinformatics analysis, the CAMTA gene family in teak was examined, and six CAMTA genes were identified in teak.

Newborn calves face challenges adapting from the warm uterine environment to cold ambient temperatures, often experiencing cold stress. The objective of this study was to assess the preferred inside hutch temperature of dairy calves in their first week after birth during Central European winter and to compare lying behavior in heated and non-heated hutches. Sixteen matched pairs of dairy calves (2.

Cold exposure has been historically used for medicinal purposes, but its benefits and associated mechanisms in mammalian organisms still remain unclear. Here, we explore the chemoprotective properties of cold temperature using a mouse model of hepatocellular carcinoma (HCC) that recapitulates several human features. Chronic cold exposure is shown to prolong lifespan in diseased mice, enhance liver health, and suppress the development of aggressive HCC, preventing hepatocellular hypertrophy, high-grade oval cell hyperplasia, liver steatosis, and aberrant hepatocyte hyperproliferation.

Hydrothermal treatment is a physical modification technology to alter starch structures for the production of resistant starch (RS). However, the underlying regulation mechanism of the multiscale structure and digestive properties of starch by dual hydrothermal synergistic treatment remains unclear. To solve this problem, A- and B-type wheat starch granules (AWS and BWS) were separated and subjected to toughening and heat-moisture synergistic treatment (THT) with various moisture content (10 %, 15 %, 20 %, 25 %).
