New Regions With Molecular Alterations in a Rare Case of Insulinomatosis: Case Report With Literature Review.

Insulinomatosis is characterized by monohormonality of multiple macro-tumors and micro-tumors that arise synchronously and metachronously in all regions of the pancreas, and often recurring hypoglycemia. One of the main characteristics of insulinomatosis is the presence of insulin-expressing monohormonal endocrine cell clusters that are exclusively composed of proliferating insulin-positive cells, are less than 1 mm in size, and show solid islet-like structure. It is presumed that insulinomatosis affects the entire population of β-cells.

TREC/KREC Levels in Young COVID-19 Patients.

COVID-19 patients with acute respiratory distress syndrome (ARDS) have an immune imbalance when systemic inflammation and dysfunction of circulating T and B cells lead to a more severe disease. Using TREC/KREC analysis, we studied the level of mature naive T and B cells in peripheral blood of COVID-19 patients and its relationship with clinical and laboratory data. TREC/KREC analysis was performed by multiplex real-time quantitative PCR on a sample of 36 patients aged 45 years or younger.

[Characteristics of immune response in elderly and autoimmunity.].

Aging is a very complex process, resulting in dysregulation of multiple systems. The most prominent changes in immunological function, termed «immunosenescence», are diminished immune response against infection, increased levels of pro-inflammatory mediators and increased risk of autoimmunity. Immunoscenescence is accompanied by the low-grade aseptic inflammation observed commonly in elderly people - «inflammaging», which is associated with a higher incidence of chronic non-infectious age-associated diseases.

Fibroin-Gelatin Composite Stimulates the Regeneration of a Splinted Full-Thickness Skin Wound in Mice.

The effects of composite fibroin-gelatin microparticles (100-250 μ) on the rate of wound healing and regeneration under conditions of contraction prevention were studied on the model of splinted full-thickness skin wound in a mouse. Subcutaneous injection of these particles into the defect area accelerated wound healing and promoted re-epithelialization and recovery of normal structure of the epidermis. In addition, the composite microparticles promoted the formation of connective tissue of characteristic structure, replacing the derma over the entire defect, and stimulated regeneration of subcutaneous muscle (panniculus carnosus) and skin appendages (sebaceous glands and hair follicles).
