Carrier screening for monogenic diseases is becoming increasingly important in preventive medicine, yet selecting appropriate target genes remains a complex task, especially in countries with significant ethnic and geographic diversity such as China. This study aimed to develop a strategy to screen for carrier screening target genes suitable for the Chinese population, considering regional variations in carrier frequencies (CFs). We analyzed a dataset from a large-scale, multicenter carrier screening study, encompassing 33,104 individuals from different regions of China and carrier status for 223 genes.

Ionic impurities including sulfate ions (SO), nitrate ions (NO) and chloride ions (Cl) formed during the preparation of TATB have negative effects on TATB-based explosives. However, strong hydrogen bonds result in extremely low solubility of TATB in traditional solvents, which poses a huge obstacle to extract and detect the impurities in TATB for quality control.

The bank slopes in the Three Gorges Reservoir area (TGRA) have experienced obvious deterioration under the action of the periodic fluctuations in the reservoir water level. Generally, laboratory tests have been used to reveal the evolution trend of the slope banks. However, this method has a certain degree of cross-scale problem, especially for the mechanical state in a complex environment.

The performance and mechanism of ammonia nitrogen removal from simulated secondary wastewater by iron-loaded biological activated carbon filter (Fe-BACF) were studied at 10 °C. The characterization results showed that iron was loaded on the surface of AC in the form of FeO, and the specific surface area, total pore volume, pore size and alkaline functional group content of Fe-AC were obviously increased.

Distribution and possible transmission route of SARS-CoV-2 in hospital environment should be clarified. We herein collected 431 environmental (391 surface and 40 air) samples in the intensive care unit (ICU) and general wards (GWs) of three hospitals in Wuhan, China from February 21 to March 4, 2020, and detected SARS-CoV-2 RNA by real-time quantitative PCR.

The characterization results indicated that the total pore volume, specific surface area and the point of zero charge of activated carbon increased after modification. A better adsorption effect was achieved under neutral condition than under alkaline or acidic condition.

Inhibiting retinal neovascularization is a potent strategy for diabetic retinopathy treatment. Reportedly, the stable expression of lin-28 homolog B (LIN28B), a member of the highly conserved RNA-binding protein LIN28 family, could promote vascular endothelial growth factor (VEGF) expression; herein, we investigated the role and mechanism of LIN28B in diabetic retinopathy progression from the perspective of microRNA (miRNA) regulation.

To clarify the possible functions and therapeutic potential of long non-coding RNAs (lncRNAs) and messenger RNAs (mRNAs) in retinal neovascularization, we assessed their expression profile in a mouse model of oxygen-induced retinopathy (OIR). Microarray analysis was performed to identify altered lncRNA and mRNA expressions between OIR and control mice.

A multicenter cross-sectional study aimed to establish a novel non-invasive score for prediction of EVs in cirrhotic patients who had never undergone endoscopy.
Methods: Patients with liver cirrhosis regardless of acute upper gastrointestinal bleeding (AUGIB) who underwent the first-time upper gastrointestinal endoscopy at 11 hospitals in Liaoning Province, China were considered.
Over-activation of beta-catenin/TCF signaling is very common in the progression of hepatocellular carcinoma (HCC). The molecular mechanisms leading to the aberrant activation of beta-catenin/TCF signaling are not fully understood. In this study, it was found that CDK7 was up-regulated in HCC tissues and its expression inversely correlated with the survival of HCC patients.

The modelling of conventional forecast methods requires enormous monitoring data that limit its application. To conduct accurate displacement prediction with limited data, a novel method is proposed and applied by integrating three computational intelligence algorithms namely: the wavelet transform (WT), the artificial bees colony (ABC), and the kernel-based extreme learning machine (KELM).

However, ps and fs laser flash photolysis provides evidence that up to 25% of the alkene product stems from carbocation that arises directly from excited diazirine rather than from the carbene.
