    The Influence of Positive Emotions on Immune Function
    (Book Rivers HN 22 Kanchan Nagar Kalyanpur Lucknow UP, 2024) Noorain Anas
    Positive emotions have been linked to a variety of beneficial health outcomes, including enhanced immune function. This paper explores the mechanisms through which positive emotions influence the immune system, examining both psychological and physiological pathways. Evidence from empirical studies suggests that individuals who experience higher levels of positive emotions, such as happiness, contentment, and gratitude, exhibit stronger immune responses, including increased antibody production and enhanced activity of natural killer cells. The role of the brain-immune connection, stress reduction, and healthy behaviors as mediators of this relationship are discussed. Implications for interventions aimed at improving emotional well-being to boost immune function are also considered. Understanding the intricate link between positive emotions and immune function can inform public health strategies and therapeutic approaches to enhance overall health and resilience.

    Strategic Management to Combat Heat Stress in Poultry Production
    (Choudhary Publishing Media, 2024) Pankaj Kumar Gupta; Vivek Pratap Singh
    The effects of heat stress (HS) caused by high temperatures continue to be a global concern in poultry production. Poultry birds are homoeothermic; however, modern day chickens are highly susceptible to HS due to their inefficiency in dissipating heat from their body due to the lack of sweat glands. During HS, the heat load is higher than the chickens' ability to regulate it. This can disturb normal physiological functioning, affect metabolism and cause behavioural changes, respiratory alkalosis and immune dysregulation in birds. These adverse effects cause gut dysbiosis and, therefore, reduce nutrient absorption and energy metabolism. This consequently reduces production performances and causes economic losses. Several strategies have been explored to combat the effects of heat stress. These include environmentally controlled houses, provision of clean cold water, low stocking density, supplementation of appropriate feed additives, dual and restricted feeding regimes, early heat conditioning and genetic selection of poultry lines to produce heat‐resistant birds. In which one best strategy is the probiotics are gaining the attention of poultry nutritionists, as they are capable of improving the physiology, gut health, and immune system of poultry under heat stress. Therefore, application of probiotics along with proper management are considered to potentially help negate some of the negative impacts of heat stress on poultry. Despite all these efforts, HS still remains a challenge in the poultry sector. Therefore, there is a need to explore effective strategies to address this long‐lasting problem.
