Summary: This study aimed to investigate the impact of serum cortisol levels and stress-related parameters on suicidal behavior in depressed patients. The results revealed that higher serum cortisol levels and perceived stress scores were significantly associated with increased suicidal severity and more fatal/non-fatal suicide attempts in depressed patients.

Summary: The main glucocorticoids involved in the stress response, such as cortisol, cortisone, and corticosterone, are widely used as biomarkers for evaluating physiological response to stress. Measurement of total glucocorticoids, which encompasses various types of glucocorticoids, is commonly performed using immunoassays. This review explores the characteristics of these glucocorticoids, techniques for their quantification, and the importance of measuring multiple types of glucocorticoids in assessing welfare.

Summary: Men often make riskier decisions than women in real-life behaviors. This study found that both men and women tend to make riskier decisions in both economic and social spheres when faced with acute psychosocial stress.

Summary: The study investigated the impact of mercuric chloride on gestation and lactation periods in mice, finding that it induced depression-like behavior and increased depression in offspring. Interestingly, administration of curcumin was found to enhance immobility, but also improve anxiety and depression behaviors compared to the mercuric chloride experimental group.

Summary: The study investigated the influence of acute stress on physiological synchrony (PS), finding that PS can occur in group settings even with minimal interaction. Exposure to stressors may affect the extent of physiological synchrony, suggesting that the phenomenon may be more widespread than previously thought.

Summary: The study found that marine algae extracts can reduce the physiological responses of aquaculture fish under stress conditions, improve feed efficiency, increase antioxidant enzyme activity, enhance immunity, and ultimately improve fish health.

Summary: This study evaluated serum cortisol levels in donkeys and found that age did not affect cortisol levels, while pregnancy increased its concentrations. Different correlations were found between cortisol, leucocyte types, and serum triglycerides.

Summary: Proper housing conditions are important for fish welfare. This study found that environmentally enriched housing conditions had minor effects on zebrafish behavior, but no significant influence on body length and stress hormone levels. It suggests that housing conditions should be considered in future research.

Summary: 2,3,5-trimethyl-3-thiazoline (TMT), a compound extracted from red fox urine, induces fear in mice, affecting their body temperature and circulating corticosterone levels. Mice exposed to TMT exhibit a freeze response and alterations in daily torpor.

Summary: In this study, the authors investigated the changes in behavioral performance and physiological stress indicators of Sebastes schlegelii juveniles with different levels of aggression. They found that high-aggressive individuals exhibited lower mobility and higher immobility than low-aggressive individuals. Principal component analysis (PCA) identified position, motion state, and physical status as behavioral screening indicators for different levels of aggression. The ratio of 5-HIAA/5-HT and cortisol levels were also significantly correlated with behavioral and physiological responses. The results suggest that behavioral factors and brain monoaminergic activity could be used to effectively distinguish individuals with different aggressiveness, offering a non-invasive method to assess fish aggression and welfare.

Summary: The study aimed to describe the composition of the hindgut microbiome in sheep under different husbandry conditions and found minimal differences in the microbiome composition, primarily related to Verrucomicrobia abundance. The investigation suggested a low-level stress across the flock, depending on management procedures, with no significant differences observed between groups.

Summary: Human serum albumin (HSA) is an important protein involved in the transportation of drugs, metabolites, nutrients, and small molecules. Researchers have discovered site-specific bioconjugation strategies for HSA that can significantly expand its role in theranostics. By screening peptide libraries, specific and covalent binding elements to HSA have been identified, along with the conjugation sites. These promising strategies have potential applications in biomedicine.

Summary: Shelters are stressful environments for domestic dogs. Evaluating dogs' welfare is crucial to improve their life condition and to promote a better management of shelters. This research aimed to analyse the physiological and behavioural responses of dogs in different environmental conditions. The presence of conspecifics is the best way to reduce stress in shelter dogs. This research could provide some useful guidelines for managing shelters and improving dogs' life condition.

Summary: This study investigated the dynamic changes of adrenocorticotrophic hormone (ACTH), cortisol, leptin, UCP1, lipids and lipoproteins in mares during late pregnancy and the postpartum period. The results suggest an interaction of the HPA axis with lipid metabolism in mares during the peripartum period to deal with metabolic load and energy demand.
