A small set of twelve compounds of a nitrofuran carboxamide chemotype was elaborated from a readily available 2,6-diazaspiro[3.4]octane building block, exploring diverse variants of the molecular periphery, including various azole substituents. The in vitro inhibitory activities of the synthesized compounds were assessed against H37Rv.

Article Synopsis
  • The study focuses on a pathogen, particularly tuberculosis (TB), which poses significant public health challenges due to issues like drug resistance and difficulties with diagnostics and treatment predictions.
  • Researchers analyzed 145 clinical strains (72 pulmonary TB and 73 extra-pulmonary TB) from Russia between 2007 and 2014 using whole-genome sequencing to identify mutations linked to drug resistance.
  • The findings reveal distinct genetic substrains related to the different TB localizations, with extra-pulmonary TB strains showing higher drug resistance, particularly associated with Beijing lineage while HIV was linked to increased occurrences of extra-pulmonary TB.

Within the general nitrofuran carboxamide chemotype, chimera derivatives incorporating diversely substituted imidazoles attached via an alkylamino linker were synthesized. Antimycobacterial evaluation against drug-sensitive M. tuberculosis H37Rv strain identified five active druglike compounds which were further profiled against patient-derived M.

Whole-genome analysis of Mycobacterium tuberculosis isolates collected in Russia (N = 71) from patients with tuberculous spondylitis supports a detailed characterization of pathogen strain distributions and drug resistance phenotype, plus distinguished occurrence and association of known resistance mutations. We identify known and novel genome determinants related to bacterial virulence, pathogenicity, and drug resistance.

Background: During the period from 1996 to 2016, we have performed 281 thymectomies in patients with various diseases of the thymus. In 179 patients, thymic pathology was associated with autoimmune myasthenia gravis (MG), and, in 108 patients, thymoma was diagnosed.

Methods: The majority of surgeries [254] were performed using video thoracoscopy, 79 of them with an additional cervical approach.

The permeability of pleural mesothelium helps to control the volume and composition of the liquid lubricating pleural surfaces. Information on pleural barrier function in health and disease, however, is scarce. Tissue specimens of human pleura were mounted in Ussing chambers for measurement of transmesothelial resistance.
