Single-Layer GaInSe: Promising Water-Splitting Photocatalyst with Solar Conversion Efficiency over 30% from Theoretical Calculations.

Hydrogen energy from solar water-splitting is known as an ideal method with which to address the energy crisis and global environmental pollution. Herein, the first-principles calculations are carried out to study the photocatalytic water-splitting performance of single-layer GaInSe under biaxial strains from -2% to +2%. Calculations reveal that single-layer GaInSe under various biaxial strains has electronic bandgaps ranging from 1.

Association of Immune Factors with Drug-Resistant Tuberculosis: A Case-Control Study.

BACKGROUND Presently, studies of factors associated with drug-resistant tuberculosis (TB) focus on patients' socio-demographic characteristics and living habits, to the exclusion of biochemical indicators, especially immune factors. This study was carried out to determine whether immune factors are associated with drug-resistant TB. MATERIAL AND METHODS A total of 227 drug-resistant pulmonary TB patients and 225 drug-susceptible pulmonary TB patients were enrolled in this study.

Mycobacterial Interspersed Repetitive Unit Can Predict Drug Resistance of Mycobacterium tuberculosis in China.

Background: Recently, Mycobacterial Interspersed Repetitive Unit (MIRU) was supposed to be associated with drug resistance in Mycobacterium tuberculosis (M. tuberculosis), but whether the association exists actually in local strains in China was still unknown. This research was conducted to explore that association and the predictability of MIRU to drug resistance of Tuberculosis (TB).

Ab initio MRCI+Q calculations on the low-lying excited states of the MgBr radical including spin-orbit coupling.

Accurate theoretical calculations on the MgBr radical have been carried out by using the high-level relativistic multireference configuration interaction method with Davidson correction (MRCI+Q) using correlation-consistent Quintuple-ζ quality basis set. The potential energy curves (PECs) of the 14 Λ-S states of MgBr have been computed. In order to improve the PECs, the core-valence correlation, scalar relativistic effect, and spin-orbit coupling effect are taken into account in the computations.

Predictive Power of ETRE Polymorphism and Katg463 Mutation to INH-Resistance of M.tuberculosis.

Background: The MIRU-VNTR polymorphism and katG463 mutation are used to genotype the mycobacterium tuberculosis, but the correlation between them and INH-resistance were unknown. This study was aimed to explore whether ETRE polymorphism and katG463 mutation could predict the INH-resistance, and the relationship between ETRE polymorphism and katG463 mutation.

Methods: The ETRE, katG463 mutation and drug resistance information of 109 M.

Drug-resistant tuberculosis can be predicted by Mycobacterial interspersed repetitive unit locus.

It is unknown whether MIRU-VNTR (Mycobacterial Interspersed Repetitive Unit-Variable Number of Tandem Repeat) is associated with drug resistance of Mycobacterium tuberculosis. The purpose of this study was to explore the ability of 24 MIRU loci to predict the drug resistance of Isoniazid (INH), Rifampicin (RFP), Streptomycin (SM), Ethambutol (EMB) and Pyrazinamide (PZA). We collected the drug resistance and MIRU loci information of 109 strains of M.

Serum cystatin C level is associated with carotid intima-media thickening and plaque.

Background And Aim: Chronic kidney disease has recently been shown to be a major risk factor for cardiovascular disease and carotid intima-media thickness has been widely used as a biomarker for early detection of cardiovascular disease. The aim of this study was to confirm whether carotid thickening and carotid plaque are associated with preclinical chronic kidney disease in individuals without clinical cardiovascular disease and chronic kidney disease.

Material And Methods: We conducted a cross-sectional study on participants from Maanshan City, China.

Correlation study of knowledge and behavior regarding breast care among female undergraduate students in China.

Background: This study aimed to understand the relationship between knowledge level and behavior on breast care in Chinese students, so as to provide strategies for improving the health education of breast care and subsequently for aiding in breast cancer prevention.

Materials And Methods: A self-designed questionnaire was used to evaluate breast care knowledge level and characterize related behavior. Correlation analysis was conducted for the knowledge level and behavior.

Roc curves of obesity indicators have a predictive value for children hypertension aged 7-17 years.

Objective: The aim of the study is to examine the distribution of integrated covariate and its association with blood pressure (BP) among children in Anhui province, China, and assess the predictive value of integrated covariate to children hypertension.
