Incorporation of the N-labeled simulated arthropod rain in the soil food web.

Direct trophic links between aboveground and belowground animal communities are rarely considered in food web models. Most invertebrate animals inhabiting aboveground space eventually become prey of soil predators and scavengers forming a gravity-driven spatial subsidy to detrital food webs, but its importance remains unquantified. We used laboratory-grown N-labeled Collembola to trace the incorporation of arthropod rain into soil food webs.

Pulmonary Hypertension-Associated Right Ventricular Cardiomyocyte Remodelling Reduces Treprostinil Function.

(1) Pulmonary hypertension (PH)-associated right ventricular (RV) failure is linked to a reduction in pulmonary vasodilators. Treprostinil has shown effectiveness in PAH patients with cardiac decompensation, hinting at potential cardiac benefits. We investigated treprostinil's synergy with isoprenaline in RV and LV cardiomyocytes.

The Carbon Isotope Composition of Epiphytes Depends Not Only on Their Layers, Life Forms, and Taxonomical Groups but Also on the Carbon and Nitrogen Indicators of Host Trees.

The carbon isotopic composition of plant tissues is a diagnostic feature of a number of physiological and ecological processes. The most important of which is the type of photosynthesis. In epiphytes, two peaks of δC values are known to correspond to C3 and CAM photosynthesis and some variants of transitional forms between them.

Caveolae-associated cAMP/Ca-mediated mechano-chemical signal transduction in mouse atrial myocytes.

Caveolae are tiny invaginations in the sarcolemma that buffer extra membrane and contribute to mechanical regulation of cellular function. While the role of caveolae in membrane mechanosensation has been studied predominantly in non-cardiomyocyte cells, caveolae contribution to cardiac mechanotransduction remains elusive. Here, we studied the role of caveolae in the regulation of Ca signaling in atrial cardiomyocytes.

Research objects were species of microorganisms representing normal gut microbiota: ATCC 25923, ATCC 25922, ATCC 24433, 791, ATCC 29212, ATCC 53103.

Mycorrhiza-feeding soil invertebrates in two coniferous forests traced with C labelling.

Mycorrhizal fungi represent a potentially abundant carbon resource for soil animals, but their role in soil food webs remains poorly understood. To detect taxa that are trophically linked to the extraradical mycelium of mycorrhizal fungi, we used stable isotope (C) labelling of whole trees in combination with the in-growth mesh bag technique in two coniferous forests. This allowed us to detect the flux of carbon in the mycelium of mycorrhizal fungi, and consequently in the tissues of soil invertebrates.

CYTOCON: The manually curated database of human in vivo cell and molecule concentrations.

Cell and cYTOkine CONcentrations DataBase (CYTOCON DB) is a project undertaken by the InSysBio team and aimed at the development of a database that allows collecting, processing, and visualizing publicly available in vivo human data on baseline concentrations of cells, cytokines, chemokines, and other molecules. Besides manual curation, an important feature of CYTOCON is that most values found in papers are converted from a huge variety of original units (i.e.

[Neurological complications and consequences of new coronavirus COVID-19 infection in elderly and old patients (literature review).].

Based on the available publications, the article systematizes information about some forms of lesions of the central nervous system (CNS), their pathogenesis, and clinical manifestations in COVID-19. Risk factors, developmental mechanisms, diagnostic approach, age characteristics of patients with neurological complications of COVID-19 are discussed. The specific mechanisms of the neuroinvasiveness and neurovirulence of the SARS-CoV-2 virus, regardless of the age of patients and the presence of risk factors, lead to systemic damage to the endothelium of small-caliber vessels, generalized thrombovasculitis, and an increased risk of ischemic and hemorrhagic strokes.

Use of hiPSC-Derived Cardiomyocytes to Rule Out Proarrhythmic Effects of Drugs: The Case of Hydroxychloroquine in COVID-19.

In the early phases of the COVID-19 pandemic, drug repurposing was widely used to identify compounds that could improve the prognosis of symptomatic patients infected by SARS-CoV-2. Hydroxychloroquine (HCQ) was one of the first drugs used to treat COVID-19 due to its supposed capacity of inhibiting SARS-CoV-2 infection and replication . While its efficacy is debated, HCQ has been associated with QT interval prolongation and potentially Torsades de Pointes, especially in patients predisposed to developing drug-induced Long QT Syndrome (LQTS) as silent carriers of variants associated with congenital LQTS.

Zetorchestes krisperi sp. nov. (Acari: Oribatida: Zetorchestidae) from Vietnam, with juvenile morphology and identification key to known species of the genus.

The description of a new species of oribatid mites (Oribatida) of the family ZetorchestidaeZetorchestes krisperi sp. nov.is proposed based on adult and tritonymph specimens collected from rainforest soil of Bi Dup-Nui Ba National Park (southern Vietnam).

Size compartmentalization of energy channeling in terrestrial belowground food webs.

Size-structured food webs form integrated trophic systems where energy is channeled from small to large consumers. Empirical evidence suggests that size structure prevails in aquatic ecosystems, whereas in terrestrial food webs trophic position is largely independent of body size. Compartmentalization of energy channeling according to size classes of consumers was suggested as a mechanism that underpins functioning and stability of terrestrial food webs including those belowground, but their structure has not been empirically assessed across the whole size spectrum.

Prokaryotic community formation on polyethylene films incubated for six months in a tropical soil.

Polyethylene film is one of the most common types of recalcitrant plastic waste materials. Information regarding the fate of plastic films in soil is scarce compared to the fate of plastic films in aquatic environments. The aim of this study was to evaluate the effects of soil fauna and of impregnation of polyethylene films with oil on the colonization of low-density polyethylene films by prokaryotic communities.

Bioimpedance Method for Human Body Hydration Assessment.

A high-precision wearable bioimpedance sensor developed at Imec was extensively tested. Unlike known bioimpedance sensors on the market, the new device enables hydration shift measurement in a single person, with no need for averaging over a population. For reaching this target, a method for hydration monitoring in case of altered hydration is tested.

[A FITZ-HUGH-CURTIS SYNDROME AS A PREMISE OF THE INFLAMMATORY DISEASES OF A HEPATOPANCREATOBILIARY ZONE ORGANS].

[The etiologic structure and biologic characteristics of agents of infections of bloodstream.].

As before, the infections of blood flow remain actual because of absence of universal approaches to their diagnostic and high lethality. Taking into account the fact that most frequently the sepsisogenic strains are selected in blood, studying of biological characteristics of hemocultures in comparison with strains isolated from other biotopes is very important for understanding the mechanisms of survival of pathogens in blood and prognosis development of septic complications. The article presents the results of microbiological analysis of blood carried out in multi-field clinic of Khanti-Mansiisk during 2007-2015.

The article investigates morphological changes in pancreas, liver, and small intestine after early enteral nutrition in Vistar rats after modeling of acute pancreatitis and creation of jejunostomy. Morphological changes and redox potential measurements show that early enteral nutrition via micro-jejunostomy slows down the development of pathological processes in Vistar rats.

Transient photocurrent in molecular junctions: singlet switching on and triplet blocking.

The kinetic approach adapted to describe charge transmission in molecular junctions, is used for the analysis of the photocurrent under conditions of moderate light intensity of the photochromic molecule. In the framework of the HOMO-LUMO model for the single electron molecular states, the analytic expressions describing the temporary behavior of the transient and steady state sequential (hopping) as well as direct (tunnel) current components have been derived. The conditions at which the current components achieve their maximal values are indicated.
