Summary: Fish cultivation in rice fields serves as a valuable resource for protein and income in rural areas, but the use of pesticides raises concerns for fish and consumer health. This study assessed the impact of pesticides on native fish in a rice field, indicating biological responses to cope with stressful environments without showing significant oxidative or neurotoxic effects throughout the production cycle.

Summary: With climate change, winter storms are expected to increase in both frequency and intensity, leading to rapid declines in water temperatures at sea-cages. In this study, Atlantic salmon were acclimated to 3 degrees C and exposed to a 'cold shock' of 0 degrees C for either 4 or 24 hours. A moderate stress response was observed, but there were no mortalities within 120 hours of the 'cold shock', suggesting that rapid declines in seawater temperature alone are unlikely to be the cause of winter-related mortalities at salmon cage-sites in Iceland and Canada.

Summary: This study constructed a nutritional metabolism-related prognostic scoring system (NMRS) for osteosarcoma patients based on analysis of hematological markers. The NMRS showed stronger predictive power compared to individual hematological indicators and served as an independent prognostic factor for the survival of osteosarcoma patients. The NMRS-based nomograms had good and stable predictive power, aiding in further risk stratification of patients with the same clinical characteristics.

Summary: In patients with FSHD, reduced physical performance is associated with lower blood levels of vitamin C, zinc, selenium, and increased oxidative stress markers. Supplementation of vitamin C, vitamin E, zinc, and selenium improves physical performance. Calorie intake is lower in women with FSHD than in men.

Summary: Temperature fluctuations caused by climate change and global warming threaten various species, especially fish. Understanding high-temperature tolerance in fish can help develop effective strategies for coping with global warming. This study investigated the effects of high temperature on Acipenser dabryanus, an ancient species of the Yangtze River, at different levels. The results showed damage to the intestine and liver tissues, increased cortisol levels and oxidative stress markers, and changes in gene and metabolite expression. The study provides insights into the heat stress response mechanisms in A. dabryanus, contributing to improved fish cultivation in response to global warming.

Summary: The complexity of the brain can lead to the development of serious neuropsychiatric disorders, such as schizophrenia. The etiopathogenesis of schizophrenia involves multiple mechanisms, highlighting its complexity and providing a new perspective for studying this disorder. This review focuses on the contribution of mitochondria, particularly oxidative damage, ROS, and energy metabolism. It also discusses the role of redox imbalance and lactate in oxidative stress, lipid peroxidation, and cognitive functions in schizophrenia.

Summary: Intermittent mild cold stimulation improves energy metabolism and stress resistance in the livers of broilers, aiding in their adaptation to low-temperature environments. Appropriate cold stimulation enhances stress resistance and mitigates the negative impact of cold environments on broilers.

Summary: Hepatic metabolic adjustments in fish are crucial in enhancing energy availability to combat stressors. Teleosts display a diversity of metabolic responses based on species biology and individual experiences. Prolonged stress triggers complex molecular responses, impacting various metabolic pathways in the liver.

Summary: Heat stress negatively affects milk production and increases disease risk in dairy cows. It alters metabolic adaptations, such as nutrient mobilization and partitioning, compromising the energy demands of lactation. Mitochondrial density and bioenergetic capacity at the cellular level play a role in meeting the changing energy requirements in response to heat stress.

Summary: The sustainability of aquaculture is affected by environmental changes, such as temperature fluctuations, which can disrupt the physiological balance of fish. In this study, we assessed the stress, immune, and antioxidant responses of pacu exposed to sudden temperature drops commonly experienced in pacu farming regions. The results showed that pacu exhibited immune activation and oxidative stress in response to the temperature drop, but was able to activate compensatory mechanisms to mitigate tissue damage. This study provides valuable insights for pacu management during periods of thermal changes.

Summary: Temperature is a crucial factor in fish physiology, and non-ideal temperature conditions can induce stress in fish. This study investigated the metabolic responses in the muscle of Astyanax lacustris fish under thermal shock, revealing changes in glycogenolysis, energy demand, protein metabolism, and oxidative stress. The integrated biomarker response index proved to be a useful tool for evaluating these metabolic changes.
