Summary: Through transcriptomic analysis, this study revealed the biological processes and molecular mechanisms of hypoxia in Takifugu rubripes. Hypoxia downregulated genes associated with the immune system and inflammation, but promoted dissolved oxygen uptake through angiogenesis and altered the expression patterns of genes involved in the inhibition of cell growth and proliferation.

Summary: Intestinal autochthonous bacteria play important roles in maintaining physiological homeostasis and host immune system. This study analyzed the variation of bacterial communities in the intestinal tract of tiger pufferfish and seawater in different aquaculture systems. Proteobacteria was the most dominant phyla, and Arcobacter was the most core bacterial taxon in the intestinal community. The differences between intestinal and seawater bacterial communities increased during the aquaculture process, and certain bacterial taxa were correlated with immune response parameters. This research is of great scientific significance for understanding intestinal bacterial homeostasis and biosecurity practice in pufferfish aquaculture.

Summary: This study tracked the foundation training of 19 young horses and assessed their emotional responses using physiological and behavioral measures. The findings suggest that behavioral responses in horses are associated with changes in salivary oxytocin concentrations, indicating its potential as a non-invasive indicator of emotional responses in young horses.

Summary: This study investigates the facial shape variation in female Japanese macaques after experimental laparotomy using geometric morphometrics. The findings suggest that tightly closed eyelids or squeezed eyes and lip tension are commonly observed facial changes after surgery, potentially indicating pain. This research emphasizes the importance of individualized assessment and enhances our understanding of facial cues to pain in captive macaques.

Summary: This study investigated the effects of anthropogenic sound exposure on captive bottlenose dolphins, demonstrating that high-level sound exposure led to increased cortisol levels and IL-10 gene transcription, with a lower IFN?/IL-10 ratio. These findings suggest that the sound stimuli used in the study could be a stressor for cetaceans, despite only minor behavioral changes being observed.

Summary: By applying different human-animal habituation strategies to beef heifers, such as positive tactile stimulation and passage through the working chute, it was found that these strategies have the potential to improve behavior and decrease physiological stress responses in cattle, leading to enhanced safety during interactions with humans.

Summary: This study found that males and females exhibit different physiological and psychological responses when facing stressors. Males showed significantly higher somatic anxiety post-startle, while females exhibited significantly higher somatic anxiety post-startle and lower self-confidence levels.

Summary: The study found that the prediction accuracy of genomic selection for standard length, body weight, and testes weight in tiger pufferfish was within an acceptable range when using 4000 or 1200 SNPs. However, predictive abilities decreased with less than 1200 SNPs due to reduced accuracy in estimating genetic relationships among individuals.

Summary: According to the World Health Organization, approximately 350 million people worldwide suffer from mental health disorders, and the search for new drugs from nature has become a research method. In this study, a standardized extract from Polygonum minus was used to evaluate its anti-stress effect in a zebrafish model, and the results showed that zebrafish is a reliable model for studying the anti-stress effect of compounds or herbal extracts.

Summary: The effect of different pre-freezing handling methods on the frozen quality of farmed obscure pufferfish was investigated. The results showed that spinal cord cutting and precooling method contributed to better quality retention compared to commercial slaughter method, and different handling methods significantly affected certain metabolic pathways, inhibiting protein denaturation and ice crystal growth.

Summary: This study investigated the association between cortisol levels and prognosis/mortality in patients admitted for acute coronary syndrome. The results showed that higher cortisol levels were correlated with specific electrocardiographic presentations and troponin I values. Additionally, cortisol levels were related to Killip-Kimball class and in-hospital mortality.

Summary: This study investigated the fluctuation patterns of physiological response after acute stress and its relationship with coping potential. The results showed that the shape of cortisol trajectories was influenced by the level of internal LOC, and higher internality was associated with greater cortisol reactivity and faster recovery.

Summary: This experiment aimed to evaluate the potential links between handling during culture with stress responses and growth on Senegalese sole. The results showed that reducing handling-derived stressors led to lower levels of circulating cortisol in the fish and promoted higher growth. The gene expression study further supported the findings of this experiment.
