Schizophrenia, a severe psychiatric, neurodevelopmental disorder affecting about 0.29-1 % of the global population, is characterized by hallucinations, delusions, cognitive impairments, disorganized thoughts and speech, leading to significant social withdrawal and emotional blunting. During the 1980s, considerations about diseases that result from complex interactions of genetic background and environmental factors started to appear.

Article Synopsis
  • The study measured the electrical impedance and pulsation ranges of brachial and femoral arteries in rats after 14 days of hindlimb unloading (a model for microgravity).
  • Results showed that the femoral artery constricted while the brachial artery dilated, with both exhibiting reduced pulsation dynamics.
  • The ability of the femoral artery to switch to an active pulsatile mode during bloodletting was significantly lower in unloaded rats than in control rats, indicating potential negative effects of microgravity on blood circulation.

Aim: To determine biomarkers of anemia of chronic disease (ACD) in patients with glomerulonephritis (GN) in the early stages of CKD, to assess their role as risk factors for cardiovascular complications (CVС).

Materials And Methods: Seventy nine patients with GN were studied, among them: 40 with primary сhronic GN (CGN), 39 with secondary forms:19 - GN with ANCA-associated systemic vasculitis, 20 - GN with systemic lupus erythematosus (SLE) at early (all I-II) CKD stages. In all patients, the level of serum C-reactive protein (CRP), hepcidin, interferon γ, and the circulating form of protein Klotho (s-Klotho) were determined.

  • Adar2 mice are commonly used to study the effects of reduced RNA editing, specifically relating to the Gria2 subunit of the AMPA receptor, which impacts their circadian rhythms.
  • The study found that Gria2 mice lost circadian rhythmicity in the hippocampus when compared to Adar2 mice, indicating a significant effect on their internal clock.
  • These findings suggest that the postnatal increase in editing of the Gria2 subunit is important for the circadian clock's development in certain brain areas, raising questions about using Gria2 mice as controls in related experiments.

Legume plants have the ability to establish a symbiotic relationship with soil bacteria known as rhizobia. The legume-rhizobium symbiosis results in the formation of symbiotic root nodules, where rhizobia fix atmospheric nitrogen. A host plant controls the number of symbiotic nodules to meet its nitrogen demands.

  • The organization of higher plants relies on a modular principle, particularly through structures known as meristems, which house stem cell pools and regulate growth and development.* -
  • The review analyzes two key molecular modules for meristem regulation: the WOX-CLAVATA module, crucial for meristem activity across types, and the florigen-activated complex, which guides phase transitions in shoot meristems.* -
  • It highlights the composition, functions, evolution, and potential applications of these modules in plant breeding and various developmental contexts.*

The fact of global climate change is generally recognized by the world scientific community. However, the spatial distribution of climatic parameters is very heterogeneous. In this regard, studies of the local response of individual territories to global climate change are of particular importance.

Potato virus Y (PVY) is one of the most dangerous agricultural pathogens that causes substantial harm to vegetative propagated crops, such as potatoes (Solanum tuberosum L.). A necessary condition for PVY infection is an interaction between the plant cap-binding translation initiation factors eIF4E and a viral protein VPg, which mimics the cap-structure.

ArdB proteins are known to inhibit the activity of the type I restriction-modification (RM-I) system, in particular EcoKI (IA family). The mechanism of ArdB's activity still remains unknown; the spectrum of targets inhibited has been poorly studied. In this work, it was shown that the presence of the ardB gene from the R64 plasmid could suppress the activity of EcoAI endonuclease (IB family) in Escherichia coli TG1 cells.

The soils of arid regions are sensitive to short-term climate changes, which are most quickly manifested in the saline state of alkaline and saline soils. Long-term climate changes are reflected in more stable soil characteristics, such as grain size distribution and microstructure. These properties can be used as indicators to assess the direction and degree of soil transformation under the influence of climate change in the longer term.

Earth's climate may be stabilized over millennia by solubilization of atmospheric carbon dioxide (CO) as minerals weather, but the temperature sensitivity of this thermostat is poorly understood. We discovered that the temperature dependence of weathering expressed as an activation energy increases from laboratory to watershed as transport, clay precipitation, disaggregation, and fracturing increasingly couple to dissolution. A simple upscaling to the global system indicates that the temperature dependence decreases to ~22 kilojoules per mole because (i) the lack of runoff limits weathering and retains base metal cations on half the land surface and (ii) other landscapes are regolith-shielded and show little weathering response to temperature.

Salinity is one of the environmental factors that affects both productivity and genetic diversity in plant species. Within the soil profile, salinity is a dynamic indicator and significantly changes with depth. The present study examined the effects of the vertical heterogeneity of soil salinity chemistry on the plant height, fresh and dry biomass accumulation, water content, level of genetic polymorphism, and observed and expected heterozygosity in seven populations of halophyte in natural habitats.

CLE (CLAVATA3/ENDOSPERM SURROUNDING REGION-related) peptides are systemic regulators of legume-rhizobium symbiosis that negatively control the number of nitrogen-fixing nodules. CLE peptides are produced in the root in response to rhizobia inoculation and/or nitrate treatment and are transported to the shoot where they are recognized by the CLV1-like (CLAVATA1-like) receptor kinase. As a result, a shoot-derived signaling pathway is activated that inhibits subsequent nodule development in the root.

  • Primary focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD) are kidney disorders characterized by damage to podocytes, leading to nephrotic syndrome, but their underlying causes remain unclear.
  • A study was conducted to analyze the urinary proteomic profiles of patients with FSGS and MCD, involving 30 FSGS and 9 MCD patients, who were categorized based on disease severity using a scoring system.
  • The results identified 22 proteins with significant differences between severe and mild cases of FSGS and MCD, with consistent patterns observed in both initial and targeted analyses, suggesting distinct proteomic signatures for each condition.

The presented clinical observation reflects the difficulties of differential diagnosis of progressive kidney damage in a patient with sarcoidosis who has undergone a new coronavirus infection. The differential circle included interstitial nephritis as an exacerbation of the underlying disease, acute drug-induced kidney injury, acute glomerulonephritis. Nephrobiopsy confirmed the diagnosis of acute sarcoid tubulointerstitial nephritis with acute tubular necrosis.

Measuring psychological attributes, such as motivation, typically involves rating scales, assuming that an attribute can be ordered, and that ratings represent this order. Previously, only the first assumption had been tested, albeit limited. First, we checked the ordinal structure of motivation, looking at whether people can establish transitive relations between motivation levels in pairwise comparisons; and we found different ordering patterns: strict transitive, weak transitive, changing order, and intransitivity.

This work describes the development of a list of monolingual word alignments taken from parallel Russian simplification data. This word lists can be used in such lexical simplification tasks as rule-based simplification applications and lexically constrained decoding for neural machine translation models. Moreover, they constitute a valuable source of information for developing educational materials for teaching Russian as a second/foreign language.

Autonomic dysfunction is frequently observed in people with epilepsy. Ictal and postictal dysautonomia is not only manifestation of autonomic seizures, but could be a life threatening condition in some cases and contribute to sudden unexpected death (SUDEP). Interictal decrease of autonomic activity is associated with duration and severity of epilepsy, it is the most prominent in focal and drug-resistant epilepsy.
