MTOR
The mammalian target of the rapamycin (mTOR) system regulates various cellular functions, such as growth, proliferation, metabolism and survival/death. In systemic organs, it is critically involved in multiple processes, including neurogenesis, nutrition and immunity. In the brain, its roles are essential in the cerebral cortical development, synaptic functions, and brain activities such as learning, cognition and social functions.

Gender Dysphoria in Children
Gender dysphoria in children (GD), also known as gender incongruence of childhood, is a formal diagnosis for children who experience significant discontent (gender dysphoria) due to a mismatch between their assigned sex and gender identity. The diagnostic label gender identity disorder in children (GIDC) was used by the Diagnostic and Statistical Manual of Mental Disorders (DSM) until it was renamed gender dysphoria in children in 2013 with the release of the DSM-5. The diagnosis was renamed to remove the stigma associated with the term disorder. Gender dysphoria in preadolescent children is more heavily linked to adult homosexuality than to an adult transgender identity, especially with regard to boys. According to prospective studies, the majority of children diagnosed with gender dysphoria cease to desire to be the other sex by puberty, with most growing up to identify as gay, lesbian, or bisexual, with or without therapeutic intervention. If the dysphoria persists during puberty, it is very likely permanent. Controversy surrounding the pathologization and treatment of a transgender identity and associated behaviors, particularly in children, has been evident in the literature since the 1980s. Proponents of the GD diagnoses argue that therapeutic intervention helps children be more comfortable in their bodies, have better peer relations and therefore better self-esteem, that research indicates there exist forms of distress associated directly with children's gender variance, and that treatment can prevent adult GD. Opponents have compared therapeutic interventions that aim to alter a child's gender identity to conversion (or reparative) therapy for gay men and lesbians. The World Professional Association for Transgender Health (WPATH) states that treatment aimed at trying to change a person's gender identity and gender expression to become more congruent with sex assigned at birth "is no longer considered ethical." Critics also argue that therapeutic interventions that aim to alter a child's gender identity rely on the assumption that an adult transgender identity is undesirable, challenging this assumption along with the lack of clinical data to support outcomes and efficacy. Other therapeutic interventions do not seek to change a child's gender identity, but are instead focused on creating a supportive and safe environment for the child to explore their gender identity and gender expression.

The Complement System in the Central Nervous System
The functions of the complement system to both innate and adaptive immunity through opsonization, cell lysis, and inflammatory activities are well known. In contrast, the role of complement in the central nervous system (CNS) which extends beyond immunity, is only beginning to be recognized as important to neurodevelopment and neurodegeneration. In addition to protecting the brain against invasive pathogens, appropriate activation of the complement system is pivotal to the maintenance of normal brain function.

Ultrasound in Medial Epicondylalgia and Medial Elbow Pain
Medial epicondylalgia (ME), commonly known as “the golfer’s elbow”, typically develops in individuals who perform repetitive forearm movements and weight-bearing activities. It accounts for up to 20% of all epicondylitis cases and is most prevalent in particular sports and occupations.

Expression, Regulation, and Physiological Relevance of Skin Aquaporins
The skin is the largest organ of the human body, serving as an effective mechanical barrier between the internal milieu and the external environment. The skin is widely considered the first-line defence of the body, with an essential function in rejecting pathogens and preventing mechanical, chemical, and physical damages. Keratinocytes are the predominant cells of the outer skin layer, the epidermis, which acts as a mechanical and water-permeability barrier. The epidermis is a permanently renewed tissue where undifferentiated keratinocytes located at the basal layer proliferate and migrate to the overlying layers.

Cytokines
Cytokines are key molecules within the tumor microenvironment (TME) that can be used as biomarkers to predict the magnitude of anti-tumor immune responses. During immune monitoring, it has been customary to predict outcomes based on the abundance of a single cytokine, in particular IFN-γ or TGF-β, as a readout of ongoing anti-cancer immunity. However, individual cytokines within the TME can exhibit dual opposing roles. For example, both IFN-γ and TGF-β have been associated with pro- and anti-tumor functions. Moreover, cytokines originating from different cellular sources influence the crosstalk between CD4+ and CD8+ T cells, while the array of cytokines expressed by T cells is also instrumental in defining the mechanisms of action and efficacy of treatments. Thus, it becomes increasingly clear that a reliable readout of ongoing immunity within the TME will have to include more than the measurement of a single cytokine.

A History of Myology
Myology is the science that studies muscles, their physical structure, type of fibers, specific function, and the connections with nerves and between different muscle groups. Interest in Myology includes also neuromuscular disorders. For most of the 20th century, Myology was considered a part of Neurology, while currently it is recognized as an autonomous discipline both at the research and the medical level. From a research point of view, we have witnessed the birth and flourishing of new scientific societies, such as the European Society for Muscle Research (1970), the Mediterranean Society of Myology (1993), the World Muscle Society (1995), the Institute of Myology (1996), the Italian Association of Myology (2000), the British Myology Society (2009), the French Society of Myology(2011), and numerous conferences concerning neuromuscular disorders, In particular, the annual meetings of the World Muscle Society and the Italian Association of Myology will have this year at their future meetings respectively in Charleston and Padova.

Wound Healing Material
Dermal wound healing describes the progressive repair and recalcitrant mechanism of damaged skin, and eventually, reformatting and reshaping the skin. Many probiotics, nutritional supplements, metal nanoparticles, composites, skin constructs, polymers, and so forth have been associated with the improved healing process of wounds. The exact mechanism of material-cellular interaction is a point of immense importance, particularly in pathological conditions such as diabetes. Bioengineered alternative agents will likely continue to dominate the outpatient and perioperative management of chronic, recalcitrant wounds as new products continue to cut costs and improve the wound healing process.

Bacteriophages
Bacteriophages, viruses that infect bacteria, have emerged as a legitimate alternative antibacterial agent with a wide scope of applications which continue to be discovered and refined. However, the potential of some bacteriophages to aid in the acquisition, maintenance, and dissemination of negatively associated bacterial genes, including resistance and virulence genes, through transduction is of concern and requires deeper understanding in order to be properly addressed. In particular, their ability to interact with mobile genetic elements such as plasmids, genomic islands, and integrative conjugative elements (ICEs) enables bacteriophages to contribute greatly to bacterial evolution. Nonetheless, bacteriophages have the potential to be used as therapeutic and biocontrol agents within medical, agricultural, and food processing settings, against bacteria in both planktonic and biofilm environments. Additionally, bacteriophages have been deployed in developing rapid, sensitive, and specific biosensors for various bacterial targets. Intriguingly, their bioengineering capabilities show great promise in improving their adaptability and effectiveness as biocontrol and detection tools.
