Summary: This study investigates the relationships between the swimming behaviors of different fish species and the three-dimensional hydrodynamic field. A model of three-dimensional swimming corridors corresponding to fish swimming characteristics is constructed. The model is verified through a fish acoustic telemetry experiment. The study provides scientific basis for the layout of fish-crossing facilities and operation of reservoirs during the fish spawning season.

Summary: In this study, a muscle-contraction model is used to explore the collective swimming of two self-propelled fish-like swimmers. A PID control algorithm is integrated into the numerical simulation model to mimic the conscious swimming control exhibited by live fish. The effects of phase difference and initial spacing on the collective behavior of the fish are investigated, and the results show that the fish can achieve the same swimming speed and observe similar flow patterns by adjusting these parameters.

Summary: The study found that the circadian clock in NIH3T3 cells can respond to periodic stimulation cycles of dexamethasone, entraining to 22 and 24-hour cycles during the stimulation period. Irregular dexamethasone treatment disrupted the expression of several clock and cell cycle genes, causing overall upregulation and phase shifts. Regular stimulation with dexamethasone also resulted in upregulation of certain genes, showing different effects compared to irregular treatment.

Summary: In modern society, stress caused by relationships and emotions is a significant social issue. This study aimed to investigate the impact of repeated restraint stress on the fatty acid composition and amino acid concentration in the skin of ICR mice. The results showed changes in fatty acid composition with an increase in saturated fatty acids and a decrease in unsaturated fatty acids, potentially leading to skin inflammation.

Summary: Metabolomic analyses of breast muscle and plasma in chickens revealed significant growth-related changes in metabolite levels between seven and 28 days of age. Some essential nutrients and growth-promoting metabolites were identified. The levels of imidazole dipeptides increased in the muscle, while taurine levels decreased. Upstream metabolites in branched-chain amino acid metabolism decreased in the muscle.

Summary: The study aimed to investigate the effects of centrally administered taurine on rectal temperature, behavioral responses, and brain amino acid metabolism under stress conditions and co-injection of corticotropin-releasing factor (CRF). The results showed that taurine attenuated CRF-induced hyperthermia and stress behaviors in neonatal chicks. Furthermore, taurine altered the concentrations of amino acids in the brain, likely by repartitioning them to different metabolic pathways to cope with acute stress.

Summary: The objective of this study was to investigate the mechanism of brain monoamine metabolism in taurine-induced hypothermia and appetite suppression. Central taurine activates dopamine-beta-hydroxylase and tryptophan hydroxylase to produce norepinephrine and 5-HT, which then induces hypothermia and anorexia, respectively.

Summary: Ornithine has been identified as a potential satiety signal in the brains of neonatal chicks. The study found that co-injection of the neuropeptide Y (NPY) and ornithine attenuated the orexigenic effect induced by NPY and modified the anabolic effect of central NPY. These findings suggest that brain ornithine interacts with NPY to regulate food intake in neonatal chicks.

Summary: This study investigated the effect of dietary and single oral administration of L-ornithine on plasma and milk levels in maternal mice. The results showed that L-ornithine intake significantly increased levels in maternal plasma and milk. However, the concentration of L-ornithine in milk was not sufficient to increase sleep-like behavior in mouse pups.

Summary: This study investigated the roles of HPV infection and EGFR exon 20 mutations in sinonasal inverted papilloma (IP) and sinonasal squamous cell carcinoma (SNSCC). HPV DNA was found in a significant percentage of IP, IP-SCC, and SNSCC cases, along with p16 overexpression. EGFR exon 20 mutations were observed in IP and IP-SCC cases but not in SNSCC. The phosphorylation pattern of EGFR with exon 20 mutations resembled that of HPV-related SNSCC and oropharyngeal cancer. Further research is needed to understand the etiology of IP-SCC.

Summary: The study found that L-ornithine can stimulate the release of GH in mice. After oral administration of L-ornithine, the increase in GH release was first observed 150 minutes later and lasted for more than 90 minutes. This increase was delayed compared to the reported levels of L-ornithine in plasma and tissues.
