Bacterial respiratory tract infections in renal allograft recipients

Bacterial infections are considered to be a serious complication in patients with immunodeficiency after kidney transplantation. Bacterial respiratory tract infection has been most common after kidney transplantation in recent years. The paper analyzes the results of kidney allotransplantation in 55 patients followed up for one week to 12 months. The recipients were found to have all known species of the bacterial flora. All the patients were postoperatively given broad-spectrum antibiotics. Antibiotic therapy was corrected after isolating the strains of microorganisms and determining their susceptibility. The therapy was continued within 7-10 days postoperatively

Negative magnetoresistance in silicon doped with manganese

Based on the developed low-temperature step-by-step diffusion of impurity manganese atoms, magnetic nanoclusters of manganese atoms were formed in the crystal lattice of silicon with controllable concentration, with specified and reproducible electrophysical parameters. With the help of electron spin resonance, it was proved experimentally that magnetic nanoclusters are formed in p-Si silicon and consist of four positively charged manganese atoms which are situated in the nearest equivalent inter-nodes around the negatively charged boron atom. Based on the study of electrophysical properties of the material obtained it is shown that in such materials an anomalous Hall effect is observed. Magnetoresistance in silicon p-Si with magnetic nanoclusters at room temperature was studied and a giant negative magnetoresistance (NMR) Δρ/ρ~300 %, was found, it was shown that with increasing concentration of nanoclusters, NMR value essentially rate

An intraoperative biopsy of native kidney in recipients with chronic kidney disease

The clinically introduced intraoperative morphological study of native kidney during transplantation of kindred kidney in patients with end-stage chronic renal failure, with intact water-excretory function before dialysis, and in the period of initiating the hemodialysis sessions significantly expanded our understanding of the pathogenesis, morphological characteristics of renal parenchyma diseases, and causes of their relapses in kidney transplant
