Aptamer's Structure Optimization for Better Diagnosis and Treatment of Glial Tumors.

Oncological diseases are a major focus in medicine, with millions diagnosed each year, leading researchers to seek new diagnostic and treatment methods. One promising avenue is the development of targeted therapies and rapid diagnostic tests using recognition molecules. The pharmaceutical industry is increasingly exploring nucleic acid-based therapeutics.

AAV Systems and Mouse Models for Investigating Ectopic Expression of Neurod1 in Transduced Cells at Subacute and Chronic Times Post-Ischemic Stroke.

Ectopic expression of neurogenic factors in vivo has emerged as a promising approach for replacing lost neurons in disease models. The use of neural basic helix-loop-helix (bHLH) transcription factors via non-propagating virus-like particle systems, including retrovirus, lentivirus, and adeno-associated virus (AAV), has been extensively reported. For in vivo experiments, AAVs are increasingly used due to their low pathogenicity and potential for translatability.

[The influence of comorbidities on treatment outcomes in patients with tuberculosis].

Aim: To study the association of comorbidities and treatment outcomes in tuberculosis (TB) patients.

Materials And Methods: A retrospective study includes all TB patients aged 18 years and older registered for treatment in Moscow in period 2021 the end of the 3rd quarter of 2022 using data of regional epidemiological TB monitoring system, a total of 3039 patients. The frequency and spectrum of comorbidities, its impact on the risk of adverse treatment outcome (ATO) and mortality using univariate and regression analysis were assessed.

Enhanced Tribodegradation of a Tetracycline Antibiotic by Rare-Earth-Modified Zinc Oxide.

Tribocatalysis is an emerging advanced oxidation process that utilizes the triboelectric effect, based on friction between dissimilar materials to produce charges that can initiate various catalytic reactions. In this study, pure and rare-earth-modified ZnO powders (LaO, EuO, 2 mol %) were demonstrated as efficient tribocatalysts for the removal of the tetracycline antibiotic doxycycline (DC). While the pure ZnO samples achieved 49% DC removal within 24 h at a stirring rate of 100 rpm, the addition of EuO increased the removal efficiency to 67%, and LaO-modified ZnO powder exhibited the highest removal efficiency, reaching 80% at the same stirring rate.
