Summary: This study investigated the expression and localization of VTG and VGR during gonad development of Pampus argenteus. The results showed that vtgs were expressed in the ovary and liver of female fish, while vgr expression in the testis was low. ELISA results indicated that VTG levels increased and then decreased during ovarian development, with peaks in the liver, serum, and ovary at different stages. VGR expression in the ovaries increased and then decreased, reaching a peak in Stage V.

Summary: The study found that silver nanoparticles (AgNPs) can impact chicken ovarian steroidogenesis, depending on exposure time, follicle type, and development stage, potentially leading to changes in selection processes. Additionally, AgNPs may affect thyroid hormone metabolism through different sizes, which could influence energy homeostasis in target cells.

Summary: The study revealed that 2,4-DCP exposure caused feminization in fish by disrupting sex hormone synthesis, which could be explained by the up-regulation of specific genes and hypomethylation of DNA. The use of fadrozole partially attenuated the feminization effect.

Summary: This study aimed to measure androgen concentrations in serum of newborn foals and investigate their association with disease severity and outcome. The results showed that increased serum androgen concentrations were correlated with disease severity and adverse outcomes in hospitalized newborn foals, while androgen levels decreased over time in healthy foals.

Summary: This study found that muscle fiber degeneration and apoptosis in silver pomfret increased when the water temperature dropped to 13 degrees C. Transcriptome analysis revealed the enrichment of several apoptosis-related pathways. RT-qPCR analysis of differentially expressed genes showed that some genes were up-regulated or down-regulated during the temperature-decreasing process. Cell experiments at different temperatures also showed that cell viability declined and apoptosis signal increased with lower temperatures, especially at 17 degrees C and 14 degrees C. The results suggest that DUSP may inhibit apoptosis in the initial stage of cold stress, but low temperature down-regulates DUSP and up-regulates JNK-C-JUN, leading to apoptosis.

Summary: In this study, a new galectin protein, SpGal-1, was identified and characterized from silver pomfret. SpGal-1 plays an important role in immune defense and exhibits high affinity for various pathogen-associated molecular patterns. Additionally, SpGal-1 shows strong binding affinity to different types of bacteria.

Summary: We studied the regulation of nutrient metabolism in silver pomfret during compensatory growth process. Our findings showed that during starvation, silver pomfret first utilized carbohydrates and short-chain lipids, followed by proteins and long-chain lipids. After re-feeding, lipids accumulated first, resulting in rapid growth, followed by the recovery of protein content in muscle. These insights provide a new perspective on the energy utilization strategies and molecular regulation during compensatory growth in fish.

Summary: The study evaluated the impact of gonadotropin in controlled-release implants and temperature manipulation on the reproduction of Astyanax altiparanae during the non-breeding season. Results showed that high temperature and GnRHa implants increased the expression of sex hormone genes in females, promoting ovarian development and follicle maturation. The combination of high temperature and GnRHa may have a positive effect on the reproduction of Astyanax altiparanae.

Summary: This study identified the SpDDX20 and SpFTZ-F1 genes in the transcriptome of mature ovarian tissue from the mud crab. The expression levels of SpFTZ-F1 and SpVTG were significantly higher in the ovaries of crabs injected with dsDDX20. Comparative transcriptome analysis revealed differentially expressed genes enriched in pathways related to ovarian steroidogenesis. The findings provide a foundation for understanding the regulation of vitellogenin expression in S. paramamosain.

Summary: Infection of Amyloodinium ocellatum in silver pomfret leads to extensive mortality. Research shows that the infection activates the immune system, increases immunity levels, causes lactic acid accumulation, and enhances immune responses. The PPAR signaling pathway plays a crucial role in improving immunity and maintaining homeostasis.

Summary: Statins may slightly impair adrenal and/or gonadal steroid hormone production, but do not cause clinically-relevant harmful effects on erectile function and spermatogenesis in men. They have beneficial effects in the treatment of polycystic ovary syndrome in women. Additional research is needed to provide specific clinical recommendations on this topic.

Summary: Steroidogenesis is a crucial process in maintaining physiological levels of steroids in the body, and its deficiency can lead to various pathologies. A research has developed a high-throughput and fully automated method for quantifying multiple steroids in human serum, achieving high sensitivity and selectivity. This method was tested on human serum samples and showed satisfactory results in line with physiological ranges reported in literature.

Summary: This study reveals that low-dose arsenic exposure has an endocrine disrupting effect on male reproductive health by stimulating Leydig cell steroidogenesis and accelerating urinary steroid excretion. This extends previous knowledge of the inverse association between high-dose arsenic exposure and sexual steroid production, which is believed to be anti-androgen.

Summary: The sex of a host influences the intensity, prevalence, and severity of helminth infection. In many cases, males are more susceptible to helminth infections than females, but there are also exceptions. This sex bias is primarily caused by ecological, behavioral, and physiological differences, and it is influenced by complex interactions between sex hormones, sex chromosomes, the microbiome, and the immune system.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
