Symptoms can predict COVID-19 pneumonia in patients infected with SARS-CoV-2 Omicron variants.

Pneumonia is a key criterion for the severity of COVID-19. Whether COVID-19 symptoms are indicators of pneumonia in patients infected with SARS-CoV-2 Omicron variants is unclear. 6200 non-hospitalized patients with COVID-19 from three sites in three hospitals were divided into three cohorts: Cohort 1 (n = 1971, Outpatient Department), Cohort 2 (n = 1073, Emergency Department), and Cohort 3 (n = 3156, Fever Clinic).

MiR-194-5p inhibited metastasis and EMT of nephroblastoma cells through targeting Crk.

Wilms tumor (WT) is the most common solid childhood tumors all over the world. MicroRNAs (miRs) contribute to tumorigenesis of various cancers through targeting gene. The present study investigated the vital role of miR-194-5p and its underlying mechanism in the progression of WT.

Characterization of multidrug resistance 1a/P-glycoprotein knockout rats generated by zinc finger nucleases.

The development of zinc finger nuclease (ZFN) technology has enabled the genetic engineering of the rat genome. The ability to manipulate the rat genome has great promise to augment the utility of rats for biological and pharmacological studies. A Wistar Hannover rat model lacking the multidrug resistance protein Mdr1a P-glycoprotein (P-gp) was generated using a rat Mdr1a-specific ZFN.

Metabolic syndrome in mice induced by expressing a transcriptional activator in adipose tissue.

Metabolic syndrome is a combination of medical disorders that increases the risk of developing cardiovascular disease and diabetes. Constitutive overexpression of 11β-HSD1 in adipose tissue in mice leads to metabolic syndrome. In the process of generating transgenic mice overexpressing 11β-HSD1 in an inducible manner, we found a metabolic syndrome phenotype in control, transgenic mice, expressing the reverse tetracycline-transactivator (rtTA) in adipose tissue.

Theoretical study of [ XN5]- (X = O, S, Se, Te) systems.

A series of [XN5]- (X = O, S, Se, Te) compounds has been examined with ab initio and Density Functional Theory (DFT) methods. The five-membered nitrogen ring series of structures are global minima and may exist or be characterized due to their significant dissociation barriers (29.7-32.
