The structure of the brachial biceps is studied based upon the bilateral dissections of six subjects. The object of this work consists of determining the distribution of the group and muscular fibers in relation to the two proximal insertions and the two distal insertions. It is possible to describe the subgroups within each structure. The objective of each of these subgroups is considered within the framework of the coordination between the two muscular formation and the double insertions on the structure of the forearm. It is probable that this muscular formation corresponds to two different movements of the forearm during the locomotory progression. This work can be utilised in the sphere of the comparative biomechanical observation. Also electromyographic and the histochemical characteristics of the muscular group.

microRNA-22 (miR-22) plays a pivotal role in the regulation of metabolic processes and has emerged as a therapeutic target in metabolic disorders, including obesity, type 2 diabetes, and metabolic-associated liver diseases. While miR-22 exhibits context-dependent effects, promoting or inhibiting metabolic pathways depending on tissue and condition, current research highlights its therapeutic potential, particularly through inhibition strategies using chemically modified antisense oligonucleotides. This review examines the dual regulatory functions of miR-22 across key metabolic pathways, offering perspectives on its integration into next-generation diagnostic and therapeutic approaches while acknowledging the complexities of its roles in metabolic homeostasis.

Type 2 diabetes mellitus (T2DM) is a common metabolic disease that is frequently accompanied by multiple complications, including diabetic myopathy, a muscle disorder that is mainly manifested as decreased muscle function and reduced muscle mass. Diabetic myopathy is a relatively common complication among patients with diabetes that is mainly attributed to mitochondrial dysfunction. Therefore, we investigated the mechanisms underlying diabetic myopathy development, focusing on the role of microRNAs (miRs).

Deterioration in muscle mass, strength, and physical performance due to conditions such as sarcopenia can affect daily activities and quality of life in the elderly. Exercise and mesenchymal stem cells (MSCs) are potential therapies for sarcopenia. This study evaluates the combined effects of exercise and adipose-derived MSCs (ADMSCs) in aged rats with sarcopenia.

The most severe form of muscular dystrophy (MD), known as Duchenne MD (DMD), remains an incurable disease, hence the ongoing efforts to develop supportive therapies. The dysregulation of autophagy, a degradative yet protective mechanism activated when tissues are under severe and prolonged stress, is critically involved in DMD. Treatments that harness autophagic capacities therefore represent a promising therapeutic approach.
