Objective: Aim: To improve the results of treatment of patients with chronic wounds of the lower extremities by using complex treatment, including surgical interventions, VAC- therapy, as well as studying the effect of negative pressure on bacterial films of wounds, based on microbiological examination and immune-histochemical data.
Patients And Methods: Materials and Methods: During the period from 2019 to 2023 at the department's clinic, 68 patients with chronic wounds of the lower extremities were examined and treated. These are mainly women (n=63) aged from 35 to 80 years.

Understanding the dynamic pathophysiology of diseases in the lung, such as asthma and chronic asthma, chronic obstructive pulmonary disease, and lung cancer, is crucial for the treatment, analysis, and outcome of these diseases. Unlike other traditional models, we suggest a protocol that is sustainable and reproducible and offers different analysis methods while maintaining in vivo lung architecture and immune dynamics. This protocol allows one to study the pathophysiological changes, including changes to the immune cells, cytokines, and mediators, in 30 precision-cut lung slices from a single murine lung.

In cutaneous melanoma, epigenetic dysregulation is implicated in drug resistance and tumor immune escape. However, the epigenetic mechanisms that influence immune escape remain poorly understood. To elucidate how epigenetic dysregulation alters the expression of surface proteins that may be involved in drug targeting and immune escape, we performed a 3-dimensional surfaceome screen in primary melanoma cultures and identified the DNA-methyltransferase inhibitor decitabine as significantly upregulating the costimulatory molecule ICAM-1.

Objective: Psoriasis is a chronic inflammatory skin disease characterized by excessive proliferation and abnormal differentiation of keratinocytes. Although stem cell-based therapies have shown promise in treating psoriasis, the underlying mechanisms remain unclear. This study aimed to established a psoriatic cell model to investigate the effect of normal dermal mesenchymal stem cell (DMSCs) on keratinocyte proliferation, inflammation responses and the associated mechanism.

Hemoglobin, composed of α- and β-chains, is essential for oxygen transport and is key in diagnosing and treating gastrointestinal and blood disorders. It also aids in detecting blood contamination and estimating transfusion volumes. Immunological methods, based on antigen-antibody interactions, are distinguished by their high sensitivity and accuracy.
