Investigating the Clinical Value of Novel Kidney Injury Inflammatory Biomarkers in Snakebite Victims.

Objective: The expression of vascular endothelial growth factor-A (VEGF-A) in snakebite patients, its value in patient prognosis and the correlation of VEGF-A with renal function were analysed.

Methods: A total of 124 snakebite patients admitted from January 2019 to January 2021 were retrospectively analysed and included in the observation group, and 40 healthy individuals who underwent physical examination in the same hospital within the same period were included in the control group. The -test was used in analysing differences between the serum VEGF-A levels of the observation and control groups and changes in VEGF-A and renal function indices before and after treatment in the observation group.

Pyrimidine catabolism is required to prevent the accumulation of 5-methyluridine in RNA.

5-Methylated cytosine is a frequent modification in eukaryotic RNA and DNA influencing mRNA stability and gene expression. Here we show that free 5-methylcytidine (5mC) and 5-methyl-2'-deoxycytidine are generated from nucleic acid turnover in Arabidopsis thaliana, and elucidate how these cytidines are degraded, which is unclear in eukaryotes. First CYTIDINE DEAMINASE produces 5-methyluridine (5mU) and thymidine which are subsequently hydrolyzed by NUCLEOSIDE HYDROLASE 1 (NSH1) to thymine and ribose or deoxyribose.

The clinical efficacy of Zuqing Xu "Wuduling" powder for snake injury on the swelling of the affected limb bitten by Agkistrodon .

To determine the clinical efficacy of Zuqing Xu 'Wuduling' powder for snake injury on the swelling of the affected limb bitten by . Sixty-five patients with bite were assigned to a treatment group ( = 35) or control group ( = 30). The treatment group was additionally given 'Wuduling' powder dressing locally based on the therapy to the control group with conventional Western medicine.

Electronic and optical properties of silicene on GaAs(111) with hydrogen intercalation: a first-principles study.

In this paper, we investigated the electronic and optical properties of silicene on GaAs(111) substrates (silicene/HGaAs) on the basis of first-principles density functional theory. The hydrogen intercalation introduced substantially weakened the interaction between silicene and the GaAs(111) substrate and induced considerable bandgaps in silicene/HGaAs heterostructures. The effects of the interlayer spacing () between silicene and the substrate, silicene buckling height (), biaxial strain (), and external electric field () on the electronic properties were also considered.

Intervalley scattering in GaAs(111)-supported silicene.

In this paper, we investigated the valley transport properties of silicene on a GaAs(111) substrate. Hydrogen atoms as intercalation substantially weaken the interaction between silicene and GaAs(111) substrate. Thus, the equivalent intervalley scattering between K valleys and the non-equivalent intervalley scattering between Γ and K valleys were studied.

A Competing-Risks Nomogram in Patients with Metastatic Pancreatic Duct Adenocarcinoma.

BACKGROUND The primary objective of this study was to assess the cumulative incidence of cause-specific mortality (CSM) and other causes of mortality (OCM) for patients with metastatic pancreatic duct adenocarcinoma (mPDAC). The secondary objective was to calculate the probability of CSM and build a competing risk nomogram to predict CSM for mPDAC. MATERIAL AND METHODS We identified patients with mPDAC between 2010 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database.

UV-B-induced anthocyanin accumulation in hypocotyls of radish sprouts continues in the dark after irradiation.

Background: Raphanus sativus L. cv. Yanghua sprouts are rich in health-promoting anthocyanins; thus hypocotyls show a red color under light.

Binding Energy and Spin-Orbit Splitting of a Hydrogenic Donor Impurity in AlGaN/GaN Triangle-Shaped Potential Quantum Well.

In the framework of effective-mass envelope function theory, including the effect of Rashba spin-orbit coupling, the binding energy E(b) and spin-orbit split energy Г of the ground state of a hydrogenic donor impurity in AlGaN/GaN triangle-shaped potential heterointerface are calculated. We find that with the electric field of the heterojunction increasing, (1) the effective width of quantum well W̅ decreases and (2) the binding energy increases monotonously, and in the mean time, (3) the spin-orbit split energy Г decreases drastically. (4) The maximum of Г is 1.

Sequential extractions and isotope analysis for discriminating the chemical forms and origins of Pb in sediment from Liaodong Bay, China.

Sequential extraction integrated with isotope analysis was carried out on a sediment core from Liaodong Bay, northeast China, for characterizing Pb in various extraction phases and its possible sources. Results show that in all extracted fractions Pb concentrations increased abruptly in the top part of the sediments that deposited after 1980, but remained lower and rather constant before 1980. Consistent with the variation pattern of Pb concentration, the 206Pb/207Pb ratio displays a dramatic decrease around 1980.
