Suppression of the Gene Affects the Level of ROS Depending on Light and Cold.

The E3 ubiquitin-protein ligase HOS1 is an important integrator of temperature information and developmental processes. HOS1 is a negative regulator of plant cold tolerance, and silencing leads to increased cold tolerance. In the present work, we studied ROS levels in plants, in which the gene was silenced by disruption of the open reading frame via CRISPR/Cas9 technology.

High production of flavonols and anthocyanins in Eruca sativa (Mill) Thell plants at high artificial LED light intensities.

Eruca sativa (arugula) is a food crop containing valuable bioactive flavonoids. Plants growing with monochrome light-emitting diodes (LED) and "binary" light sources, including red/blue (RB), were tested using HPLC-DAD-ESI-MS/MS. Most artificial lighting options with a high intensity of 1000 μmol ms (except for warm white light) resulted in an almost 20-fold increase in flavonol productivity.

The Nature of Ferromagnetism in a System of Self-Ordered α-FeSi Nanorods on a Si(111)-4° Vicinal Surface: Experiment and Theory.

In this study, the appearance of magnetic moments and ferromagnetism in nanostructures of non-magnetic materials based on silicon and transition metals (such as iron) was considered experimentally and theoretically. An analysis of the related literature shows that for a monolayer iron coating on a vicinal silicon surface with (111) orientation after solid-phase annealing at 450-550 °C, self-ordered two-dimensional islands of α-FeSi displaying superparamagnetic properties are formed. We studied the transition to ferromagnetic properties in a system of α-FeSi nanorods (NRs) in the temperature range of 2-300 K with an increase in the iron coverage to 5.

UHMWPE/CaSiO Nanocomposite: Mechanical and Tribological Properties.

This paper studied the effect of additives of 0.5-20 wt.% synthetic CaSiO wollastonite on the thermodynamic, mechanical, and tribological characteristics and structure of polymer composite materials (PCM) based on ultra-high-molecular weight polyethylene (UHMWPE).

[The efficiency of combination therapy of non-gonococcal urethritis in men].

Aim: To carry out a comparative assessment of the efficiency of combination therapy for non-gonococcal urethritis (NGU) in men.

Materials And Methods: a total of 124 patients with NGU and laboratory-confirmed urogenital infection were included in the study. The diagnostic methods included microscopy of urethral smear, real-time polymerase chain reaction (PCR) for the detection of uropathogens and laser Doppler flowmetry for evaluating the urethral microcirculation.
