The etiology of sarcopenia is multifactorial but still poorly understood, and the sequelae of this phenomenon represent a major public health issue. Age-related loss of muscle mass can be counteracted by adequate metabolic interventions including nutritional intake and exercise training. Other strategies including changes in daily protein pattern, the speed of protein digestion, or specific amino acid supplementation may be beneficial to improve short-term muscle anabolic response in elderly people. A multimodal approach combining nutrition, exercise, hormones, and specific anabolic drugs may be an innovative treatment for limiting the development of sarcopenia with aging.

Glutamate (Glu) is a crucial excitatory neurotransmitter in the central nervous system that transmits brain information by activating excitatory receptors on neuronal membranes. Physiological studies have demonstrated that abnormal Glu metabolism in astrocytes is closely related to the pathogenesis of epilepsy. The astrocyte metabolism processes mainly involve the Glu uptake through astrocyte EAAT2, the Glu-glutamine (Gln) conversion, and the Glu release.

Introduction: Since mechanical thrombectomy has allowed ischemic stroke thrombi retrieval, its exhaustive study has involved a better knowledge of physiopathological processes implied in its formation.
Development: Thrombotic pathways involved in the different vascular beds shared common mechanisms conditioning difficulties in the identification of specific patterns associated with stroke etiology. Other factors as clot formation time, associated inflammatory status or activation of additional immune and coagulation pathways [Neutrophil extracellular traps (NETs) delivery, platelet aggregation, endothelial activation and VonWillebrand Factor release] have been described as determinants in thrombus characteristics.

Understanding biological mechanisms underlying anorexia nervosa (AN) is necessary to develop care strategies. Despite many articles dedicated to peptides assessment in AN, there is no systematic review. A scoping review of circulating peptides published in relation to AN, comparing their results with those of controls, was conducted.

The neuropathological signature of Alzheimer's disease (AD) comprises mainly amyloid plaques, and neurofibrillary tangles, resulting in synaptic and neuronal loss. These pathological structures stem from amyloid dysfunctional metabolism according to the amyloid cascade hypothesis, leading to the formation of plaques, and apparently inducing the initiation of the abnormal tau pathway, with phosphorylation and aggregation of these proteins, ultimately causing the formation of tangles. In this narrative review, the existing hypothesis related to the pathophysiology of AD were compiled, and biological pathways were highlighted in order to identify the molecules that could represent biological markers of the disease, necessary to establish early diagnosis, as well as the selection of patients for therapeutical interventional strategies.

Histone lactylation is crucial in a variety of physiopathological processes, however, the function and mechanism of histone lactylation in endometriosis remain poorly understood. Therefore, the objective of this investigation was to illuminate the function and mechanism of histone lactylation in endometriosis. Immunohistochemistry was used to investigate the expression of histone lactylation.
