HEMOPERFUSION USING THE LPS-SELECTIVE MESOPOROUS POLYMERIC ADSORBENT IN SEPTIC SHOCK: A MULTICENTER RANDOMIZED CLINICAL TRIAL.

Extracorporeal hemoperfusion (EHP) may improve the course and outcomes of patients with septic shock by targeting cytokines or bacterial endotoxins (lipopolysaccharide [LPS]). Here, we present the results of a multicenter randomized controlled trial ( clinicaltrials.gov/ct2/show/NCT04827407 ) to assess the efficiency and safety of Efferon LPS hemoperfusion cartridges engineered for multimodal targeting LPS, host-derived cytokine, and damage-associated molecule pattern molecules.

Association of NEF2L2 Rs35652124 Polymorphism with Nrf2 Induction and Genotoxic Stress Biomarkers in Autism.

Increased oxidative/genotoxic stress is known to impact the pathophysiology of ASD (autism spectrum disorder). Clinical studies, however, reported limited, heterogeneous but promising responses to treatment with antioxidant remedies. We determined whether the functional polymorphism of the Nrf2 gene, master regulator of anti-oxidant adaptive reactions to genotoxic stress, links to the genotoxic stress responses and to an in vitro effect of a NRF2 inductor in ASD children.

Picosecond Yb-doped tapered fiber laser system with 1.26 MW peak power and 200 W average output power.

We demonstrate a compact picosecond master-oscillator power-amplifier (MOPA) system based on an Yb-doped polarization-maintaining double-clad tapered fiber (T-DCF) delivering pulses with over 1.26 MW peak power and average output power up to 200 W preserving near diffraction limited beam quality. The unique properties of an active tapered fiber enable to amplify the seed pulses directly with no need for applying of additional stretching technique.

Fibulin-5 (FBLN5) gene polymorphism is associated with pelvic organ prolapse.

Objective: FBLN5 encodes a key protein of elastic fiber matrix assembly and function that contributes to maintaining pelvic support and plays the important role in the pathophysiology of pelvic organ prolapse (POP). The aim of the study was to investigate whether there is an association between common single-nucleotide polymorphisms (SNPs) of the FBLN5 gene and POP.

Study Design: A total of eleven tag SNPs of the FBLN5 gene were genotyped using the polymerase chain reaction with confronting two-pair primers (PCR-CTPP) in 210 patients with POP (stages III-IV) and 292 controls with no even minimal POP.

[Genetic and cytogenetic predictors of human chromosomal radiosensitivity].

We studied association between the frequencies of gamma-induced (1 Gy in vitro) chromosome aberrations in blood lymphocytes and polymorphism of 45 repair candidate genes, detoxification and oxidative stress genes (53 sites) for 99 healthy volunteers. The levels of chromosome-type aberrations correlated with carriage of the minor alleles of the genes OGG1 Ser326Cys, ABCB1 Ile1145 = and NQO1 Pro187Ser (p = 0.0002).
