The Senescence-Associated Secretory Phenotype (SASP) is a hallmark of cellular senescence, characterized by the robust secretion of bioactive molecules such as pro-inflammatory cytokines, chemokines, matrix metalloproteinases, and growth factors by senescent cells. Through paracrine and autocrine mechanisms, the SASP induces chronic low-grade inflammation in local and systemic microenvironments ...

Fibular (peroneal) neuropathy is the most common mononeuropathy of the lower limb and a frequent cause of foot drop, most often occurring at the fibular head.

Immunity is a basic feature of life. Some immunological mechanisms are not completely understood. Burnet’s Clonal selection Theory barely explains how a limited number of immune cell clones can ensure immunity to numerically superior antigenic determinants, and how strict timing of immune reactions can be achieved.

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is transmitted between humans through aerosols. It is assumed that protective face masks prevent the spread of SARS-CoV-2. However, face masks vary in their type and efficacy and the reported effectiveness of face masks to prevent the spread of SARS-CoV-2 has varied although the reason for this variation is not well understood.
