Fitness of Outer Membrane Vesicles From Is Altered Under the Impact of Simulated Mars-like Stressors Outside the International Space Station.

Outer membrane vesicles (OMVs), produced by nonpathogenic Gram-negative bacteria, have potentially useful biotechnological applications in extraterrestrial extreme environments. However, their biological effects under the impact of various stressors have to be elucidated for safety reasons. In the spaceflight experiment, model biofilm kombucha microbial community (KMC) samples, in which was a dominant community-member, were exposed under simulated Martian factors (i.

Fatty acids composition of inner mitochondrial membrane of rat cardiomyocytes and hepatocytes during hypoxia-hypercapnia.

We studied the influence of hypoxic-hypercapnic environment under the effect of hypothermia (artificial hibernation) on fatty acids spectrum of inner mitochondrial membrane (IMM) lipids of rat cardiomyocytes and hepatocytes. Specific for cellular organelles redistribution of IMM fatty acids was determined. It led to the reduction of total amount of saturated fatty acids (SFAs) and increase of unsaturated fatty acids (UFAs) in cardiomyocytes and to the increase of SFAs and decrease of UFAs in hepatocytes.

[Sinus lift and dental implantation after endosurgical treatment of odontogenic maxillary sinusitis].

The long-term results of dental implant placement in patients with the history of odontogenic maxillary sinusitis are assessed in retrospective study. Maxillary sinusotomy and endoscopic surgery procedures are compared in regard to complications risks after subsequent sinus lift and dental implantation, the latter proving to be method of choice in such cases.

[Mandible bone grafting by intraoral access].

The efficiency of intraoral approach to reconstruction defects of the mandibula was analyzed. Received results testified to high efficiency of intraoral approach to bone plastic of mandibula as the way allowing to achieve decrease of number of postoperative complications, terms of rehabilitation of patients and to ensure optimum anatomofunctional and aesthetic results.

[Complications of dental filling materials egestion into maxillary sinus--diagnostics and treatment].

Frequency of dental filling materials egestion into maxillary sinus was determined. Based upon their own clinical observations sinusitis (caused by dental filling material) characteristic features were determined, as well as diagnostic peculiarities. Open and endoscopic methods of treatment were compared.
