[Bilateral stenting for malignant tracheal and bronchial stenosis].

Malignant lesions of tracheal bifurcation usually lead to respiratory failure and risk of mortality. Airway stenting is the only minimally invasive method for these patients. The authors present a patient with T4N3M0 left-sided lung cancer (inoperable stage IIIc) complicated by respiratory failure due to tracheal bifurcation obstruction.

Endoscopic transluminal drainage for infected pancreatic necrosis.

Objective: To evaluate the effectiveness of intraluminal drainage of acute fluid accumulations for infected pancreatic necrosis.

Material And Methods: There were 848 patients with acute pancreatitis between January 2018 and December 2020 at the Sklifosovsky Research Institute for Emergency Care. Necrotizing pancreatitis was detected in 232 (27.

[Diagnosis and surgical treatment of symptomic stomach diverticulum].

Gastric diverticulum is a rather rare disease. This lesion is diagnosed in about 0.01% of cases during contrast-enhanced X-ray examination and in 0.

Extensive Contamination of Water with Saxitoxin Near the Dam of the Irkutsk Hydropower Station Reservoir (East Siberia, Russia).

An area of discolored water 50 m wide and 30 m long was found in September 2017 close to the dam of the Irkutsk hydroelectric power station. Water from this spot was sampled for investigation in the present study. Microscopic analysis revealed that the suspended matter in the sample was composed of clumps of filaments, vegetative cells, akinetes and heterocysts that formed short filaments and solitary cells.

Flagellin-fused protein targeting M2e and HA2 induces potent humoral and T-cell responses and protects mice against various influenza viruses a subtypes.

Background: Current influenza vaccines are mainly strain-specific and have limited efficacy in preventing new, potentially pandemic, influenza strains. Efficient control of influenza A infection can potentially be achieved through the development of broad-spectrum vaccines based on conserved antigens. A current trend in the design of universal flu vaccines is the construction of recombinant proteins based on combinations of various conserved epitopes of viral proteins (M1, M2, HA2, NP).
