[Features of histo- and angioarchitectonics of the prostate during the progression of bph and the development of its complications].

Introduction: Prostatic hyperplasia (BPH) is one of the most common diseases of elderly and senile men. Its natural "evolution" leads to an increase in deformity disorders, gradual decompensation of the bladder and the progression of CKD. If the morphogenesis of BPH, as well as the patterns of adaptive and pathological restructuring of the lower urinary tract are described in the literature, then there is practically no evidence of adaptive processes in the prostate itself against the background of the growth of hyperplasia nodes.

Biallelic Loss of 7q34 () and 9p21.3 (/) in Adult Ph-Negative Acute T-Lymphoblastic Leukemia.

Tumor cells of acute lymphoblastic leukemia (ALL) may have various genetic abnormalities. Some of them lead to a complete loss of certain genes. Our aim was to reveal biallelic deletions of genes in Ph-negative T-ALL.

Loss of Heterozygosity and Mutations in the RAS-ERK Pathway Genes in Tumor Cells of Various Loci in Multiple Myeloma.

Multiple myeloma (MM) is a disease characterized by spatiotemporal heterogeneity of tumor clones. Different genetic aberrations can be observed simultaneously in tumor cells from different loci, and as the disease progresses, new subclones may appear. The role of liquid biopsy, which is based on the analysis of tumor DNA circulating in the blood plasma, continues to be explored in MM.

An insight into the effect of interaction with protein on antibacterial activity of chitosan derivatives.

Antimicrobial activity of chitosan in protein-rich media is of a particular interest for various protein-based drug delivery and other systems. For the first time, bacteriostatic activity of chitosan derivatives in the presence of caseinate sodium (CAS) was studied and discussed. Complexation of chitosan derivatives soluble in acidic (CH and RCH) or alkalescent (RCH) media with CAS was confirmed by fluorescent spectroscopy, turbodimetry, light scattering data and measurement of electrical potentials of CAS/chitosan derivative complexes.

DNA Copy Number Alterations and Copy Neutral Loss of Heterozygosity in Adult Ph-Negative Acute B-Lymphoblastic Leukemia: Focus on the Genes Involved.

The landscape of chromosomal aberrations in the tumor cells of the patients with B-ALL is diverse and can influence the outcome of the disease. Molecular karyotyping at the onset of the disease using chromosomal microarray (CMA) is advisable to identify additional molecular factors associated with the prognosis of the disease. Molecular karyotyping data for 36 patients with Ph-negative B-ALL who received therapy according to the ALL-2016 protocol are presented.
