Oral rivaroxaban for the treatment of deep vein thrombosis in outpatients: a propensity score-matched comparison with a historical inpatient population.

Background: Despite the guidelines' appeal to treat patients with deep vein thrombosis and low-risk pulmonary embolism in outpatient settings, the real-world evidence shows a high prevalence of inpatient therapy leading to unwarranted health resource utilization. The study aimed to assess the efficacy and safety of rivaroxaban in outpatient settings compared to inpatient treatment.

Methods: A propensity score-matched comparison with a historical inpatient population was performed based on a retrospective analysis of patients with deep vein thrombosis and without pulmonary embolism treated as outpatients with oral rivaroxaban.

Zhabe horses are traditional type of indigenous Kazakh horses characterized by versatility and adaptation to conditions of Central Asia. The present work focuses on examination of genetic structure of Zhabe horses using SNP genotyping with addition of previously published data.

The heterogeneity of aqueous solutions: the current situation in the context of experiment and theory.

The advancement of experimental methods has provided new information about the structure and structural fluctuations of water. Despite the appearance of numerous models, which aim to describe a wide range of thermodynamic and electrical characteristics of water, there is a deficit in systemic understanding of structuring in aqueous solutions. A particular challenge is the fact that even pure water is a heterogeneous, multicomponent system composed of molecular and supramolecular structures.

Understanding and applying biological resilience, from genes to ecosystems.

The natural world is under unprecedented and accelerating pressure. Much work on understanding resilience to local and global environmental change has, so far, focussed on ecosystems. However, understanding a system's behaviour requires knowledge of its component parts and their interactions.

Association of polymorphic variants of prolactin (PRL) and beta-lactoglobulin (BLG) genes with resistance/susceptibility to mastitis in holstein cows.

The work aims to analyze the associations of polymorphic variants of the PRL and BLG genes with resistance and susceptibility to mastitis in Holstein cows. The experimental study consisted of the selection of biomaterial samples from 250 heads of Holstein cows aged 3 years divided into two groups (healthy and with a confirmed diagnosis of mastitis). The determination of animal genotypes was carried out using polymerase chain reaction and restriction fragment length polymorphism.

Using Machine Learning Algorithms to Determine the Post-COVID State of a Person by Their Rhythmogram.

This study introduces a novel method for detecting the post-COVID state using ECG data. By leveraging a convolutional neural network, we identify "cardiospikes" present in the ECG data of individuals who have experienced a COVID-19 infection. With a test sample, we achieve an 87 percent accuracy in detecting these cardiospikes.

Fisheye piezo polymer detector for scanning optoacoustic angiography of experimental neoplasms.

A number of optoacoustic (or photoacoustic) microscopy and mesoscopy techniques have successfully been employed for non-invasive tumor angiography. However, accurate rendering of tortuous and multidirectional neoplastic vessels is commonly hindered by the limited aperture size, narrow bandwidth and insufficient angular coverage of commercially available ultrasound transducers. We exploited the excellent flexibility and elasticity of a piezo polymer (PVDF) material to devise a fisheye-shape ultrasound detector with a high numerical aperture of 0.

Genetic polymorphism of prolactin and nitric oxide synthase in Holstein cattle.

Background And Aim: Bacterial and viral infections affect the welfare of animals and lead to large economic losses in dairy cattle breeding due to decreased productive indicators and increased culling rates. In modern dairy farming, farmers are looking for effective solutions to prevent and minimize infectious disease risks. To this end, the most relevant study field is the search for gene sites that impact production and health.

A Pentavalent LPS-Based Vaccine Candidate Is Safe and Immunogenic in Animal Models.

A multivalent vaccine is much needed to achieve protection against predominant serotypes. Recently, we demonstrated the clinical applicability and immunogenic potential of tri-acylated 2a lipopolysaccharide (Ac-S-LPS). Using a similar approach, we designed a pentavalent LPS candidate vaccine against 1b, 2a, 3a, 6, and Y (PLVF).

High-Level Production of Soluble Cross-Reacting Material 197 in Cytoplasm Due to Fine Tuning of the Target Gene's mRNA Structure.

Cross-reacting material 197 (CRM197) is a non-toxic mutant of the diphtheria toxin and is widely used as a carrier protein in conjugate vaccines. This protein was first obtained from the supernatant of the mutant strain. This pathogenic bacteria strain is characterized by a slow growth rate and a relatively low target protein yield, resulting in high production costs for CRM197.

Empirical Parameter to Compare Molecule-Electrode Interfaces in Large-Area Molecular Junctions.

This paper describes a simple model for comparing the degree of electronic coupling between molecules and electrodes across different large-area molecular junctions. The resulting coupling parameter can be obtained directly from current-voltage data or extracted from published data without fitting. We demonstrate the generalizability of this model by comparing over 40 different junctions comprising different molecules and measured by different laboratories.

Noninvasive optoacoustic microangiography reveals dose and size dependency of radiation-induced deep tumor vasculature remodeling.

Tumor microvascular responses may provide a sensitive readout indicative of radiation therapy efficacy, its time course and dose dependencies. However, direct high-resolution observation and longitudinal monitoring of large-scale microvascular remodeling in deep tissues remained challenging with the conventional microscopy approaches. We report on a non-invasive longitudinal study of morphological and functional neovascular responses by means of scanning optoacoustic (ОА) microangiography.

The Highly Productive C1 Expression System as a Host for Rapid Development of Influenza Vaccines.

(1) Influenza viruses constantly change and evade prior immune responses, forcing seasonal re-vaccinations with updated vaccines. Current FDA-approved vaccine manufacturing technologies are too slow and/or expensive to quickly adapt to mid-season changes in the virus or to the emergence of pandemic strains. Therefore, cost-effective vaccine technologies that can quickly adapt to newly emerged strains are desirable.

[Flow cytometry evaluation of the rhesus monkey cellular immunity following the Zaire ebolavirus (Filoviridae; Ebolavirus: Zaire ebolavirus) experimental infection].

Introduction: The outbreaks of the Zaire ebolavirus (ZE) disease (ZED) that have arisen in the last decade determine the need to study the infection pathogenesis, the formation of specific immunity forming as well as the development of effective preventive and therapeutic means. All stages of fight against the ZED spread require the experimental infection in sensitive laboratory animals, which are rhesus monkeys in case of this disease .The aim of the study is to evaluate the rhesus monkey cellular immunity following the ZE experimental infection by the means of flow cytometry (cytofluorimetry).

The combined action of CTCF and its testis-specific paralog BORIS is essential for spermatogenesis.

CTCF is a key organizer of the 3D genome. Its specialized paralog, BORIS, heterodimerizes with CTCF but is expressed only in male germ cells and in cancer states. Unexpectedly, BORIS-null mice have only minimal germ cell defects.
