Exercise and fasting, by activating hypothalamic neurons, lead to appetite regulation, increased energy efficiency, increased brown fat cells, and weight loss. Additionally, fasting and exercise affect brain plasticity and cognitive function by reducing oxidative brain damage and increasing brain-derived neurotrophic factor (BDNF), potentially reducing the risk of neurological diseases. In humans, these lifestyle interventions can also modulate autophagy and apoptosis in lymphocytes, especially natural killer (NK) cells, T cells, and B cells, which play an important role in fighting cancer and virus-infected cells. Fasting and exercise increase the concentration of autophagic monocytes, enhance killer T lymphocytes, strengthen the immune system, and delay cancer progression. Fasting and exercise can improve metabolic and inflammatory parameters through immune-related molecules, reducing systemic inflammation. Furthermore, they are associated with changes in the composition and function of gastrointestinal microbes, including an increase in beneficial microbes and a decrease in pathogenic bacteria, along with intestinal epithelial integrity.

The molecular clock exhibits distinct characteristics across various tissues and can be synchronized by particular stimuli. Furthermore, there is an intricate interplay among the molecular clocks within different tissues. In this context, we present an overview of the tissue-specific molecular clock and discuss pivotal nonphotic regulators that govern the host's circadian rhythms and metabolic processes.

Background: During intense exercise, anaerobic metabolism predominantly produces energy in the body, resulting in lactic acid (LA) accumulation, which contributes to muscle fatigue and soreness and may also impair neurological and cardiovascular functions. In endurance sports, the lactate threshold (LT) is a key indicator of an athlete's capacity to clear and utilize LA, directly influencing athletic performance and endurance. Therefore, LA detection is crucial for assessing the physical condition of both athletes and the general population, as well as for optimizing training programs.

Unlabelled: Obesity is a pervasive global health issue frequently associated with metabolic syndrome (MetS). Limited data exist regarding the impact of MetS and its individual components on pulmonary function in obese pediatric populations. This study investigated the relationship between MetS and lung function, and further identified specific MetS components that adversely affect pulmonary outcomes.

Background: Despite growing interest in women's physiology in exercise sciences, the understanding of female athletes' energy metabolism remains limited. This study aimed to analyze substrate oxidation in response to energetic stimuli in female athletes using or not hormonal contraceptives, and to determine the influence of the estradiol-to-progesterone ratio fluctuations on energy metabolism.
Methods: Body composition (dual-energy X-ray absorptiometry), energy expenditure and substrate oxidation rates (resting, low-intensity walking exercise (4 km/h), and postprandial conditions; indirect calorimetry) were assessed among 32 athletes (23±3 years) during a high-training load period, in athletes using or not hormonal contraceptives (nine and 23, respectively).

Doxorubicin (DOX)‑induced cardiotoxicity (DIC) remains a critical challenge in cancer therapy, significantly limiting its use in clinical practice. The underlying mechanisms involve disruptions in cardiac metabolism and mitochondrial dysfunction. The heart relies on mitochondrial oxidative phosphorylation to produce ATP, which is essential for maintaining both contraction and relaxation.
