The asymptomatic ocular surface reservoir of coronavirus disease-19 in infants and retinopathy of prematurity screening during the pandemic.

Purpose: This study aimed to evaluate the incidence of conjunctival and pharyngeal swab sample positivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in asymptomatic preterm and term infants. We aimed to detect asymptomatic carrier potential in infants.

Materials And Methods: Patients screened for retinopathy of prematurity (ROP) at our clinic between January and June 2021 were recruited for this study.

Prevalence of carbapenemases in Enterobacterales from urine specimens in an university hospital in Istanbul, Turkey.

We aimed to investigate the prevalence of carbapenemases in Enterobacterales strains isolated from urine specimens between July 2019 and July 2020.CIM and modified CIM tests were applied as well as detection of blaOXA-48, blaNDM, blaVIM, blaKPC and blaIMP genes was performed by multiplex PCR.One hundred fifty of 3,242 Enterobacterales strains were found to be carbapenem resistant and 46 were included in the study.

The Influence of on Levodopa-Induced Dyskinesia.

Background: Dopamine deficiency causes Parkinson's disease (PD), and on treatment, levodopa is the gold standard. Various drug-metabolizing enzymes and drug receptors are believed to be involved in prompting dyskinesias due to the extended usage of levodopa. Shreds of evidence in genomic studies have presented that ADORA2A receptor antagonism has beneficial outcomes to avoid these drug-induced side effects.

miRNAs as cell fate determinants of lateral and paraxial mesoderm differentiation from embryonic stem cells.

To date, the role of miRNAs on pluripotency and differentiation of ESCs into specific lineages has been studied extensively. However, the specific role of miRNAs during lateral and paraxial mesoderm cell fate decision is still unclear. To address this, we firstly determined miRNA profile of mouse ESCs differentiating towards lateral and paraxial lineages which were detected using Flk1 and PDGFαR antibodies, and of myogenic and hematopoietic differentiation potential of purified paraxial and lateral mesodermal cells within these populations.

Long-term chronic caloric restriction alters miRNA profiles in the brain of ageing mice.

Calorie restriction (CR) has been shown to be one of the most effective methods in alleviating the effects of ageing and age-related diseases. Although the protective effects of CR have been reported, the exact molecular mechanism still needs to be clarified. This study aims to determine differentially expressed (DE) miRNAs and altered gene pathways due to long-term chronic (CCR) and intermittent (ICR) CR in the brain of mice to understand the preventive roles of miRNAs resulting from long-term CR.
