Prevalence and influencing factors of occupational burnout among healthcare workers in the Chinese mainland during the late 2022 Omicron COVID-19 outbreak: a multicenter cross-sectional study.

China witnessed an Omicron COVID-19 outbreak at the end of 2022. During this period, medical crowding and enormous pressure on the healthcare systems occurred, which might result in the occurrence of occupational burnout among healthcare workers (HCWs). This study aims to investigate the prevalence of occupational burnout and associated mental conditions, such as depressive symptoms, anxiety, PTSD symptoms, perceived social support, resilience, and mindfulness among HCWs of the Chinese mainland during the Omicron COVID-19 outbreak, and to explore the potential risk and protective factors influencing occupational burnout of HCWs.

Ferroelectricity with concomitant Coulomb screening in van der Waals heterostructures.

Interfacial ferroelectricity emerges in non-centrosymmetric heterostructures consisting of non-polar van der Waals (vdW) layers. Ferroelectricity with concomitant Coulomb screening can switch topological currents or superconductivity and simulate synaptic response. So far, it has only been realized in bilayer graphene moiré superlattices, posing stringent requirements to constituent materials and twist angles.

Novel susceptibility genes for sleep apnea revealed by a cross-tissue transcriptome-wide association study.

Sleep apnea (SA) is a sleep disorder characterized by frequent interruptions in breathing during sleep and is widely recognized as a significant global public health concern. Although genome-wide association studies (GWAS) have identified several loci associated with SA susceptibility, the underlying genes and biological mechanisms remain largely unknown. A cross-tissue transcriptome-wide association study (TWAS) was performed to integrate SA GWAS summary statistics from 410,385 individuals (43,901 cases and 366,484 controls) and gene expression data from 49 distinct tissues and obtained from 838 post-mortem donors.

However, the roles of these RNA modifications in the tumor microenvironment (TME) are still unknown.

Single-cell multi-omics deciphers hepatocyte dedifferentiation and illuminates maintenance strategies.

Due to the similarity to human hepatocytes, porcine hepatocytes play an important role in hepatic research and drug evaluation. However, once hepatocytes were cultured in vitro, it was often prone to dedifferentiate, resulting in the loss of their characteristic features and normal functions, which impede their application in liver transplantation and hepatotoxic drugs evaluation. Up to now, this process has yet to be thoroughly investigated from the single-cell resolution and multi-omics perspective.

Assembly and functional mechanisms of plant NLR resistosomes.

Nucleotide-binding and leucine-rich repeat (NLR) proteins are essential intracellular immune receptors in both animal and plant kingdoms. Sensing of pathogen-derived signals induces oligomerization of NLR proteins, culminating in the formation of higher-order protein complexes known as resistosomes in plants. The NLR resistosomes play a pivotal role in mediating the plant immune response against invading pathogens.

Engineering a DNA polymerase for modifying large RNA at specific positions.

The synthesis of large RNA with precise modifications at specific positions is in high demand for both basic research and therapeutic applications, but efficient methods are limited. Engineered DNA polymerases have recently emerged as attractive tools for RNA labelling, offering distinct advantages over conventional RNA polymerases. Here, through semi-rational designs, we engineered a DNA polymerase variant and used it to precisely incorporate a diverse range of modifications, including base modifications, 2'-ribose modifications and backbone modifications, into desired positions within RNA.

B(MIDA)-directed site-selective intermolecular halofluoroalkylation of alkenes: synthesis of diversely functionalized building blocks.

α-Halo borides are generally constructed Matteson homologation, and the synthesis of both fluorinated and functionalized ambiphilic boronates is challenging and has received inadequate attention. Herein, we describe the -methyliminodiacetyl boronate [B(MIDA)]-directed halogenation of alkenes a complementary sequence involving fluoroalkyl radical addition followed by guided radical-to-metal oxidative addition and C-X reductive elimination. The alkali cation and functional groups in B(MIDA) enable coulombic interaction and weak attraction with halogens, which could weaken the Pd-X bond and assist in C-X bond formation and is verified by DFT calculations.

Decoupling many-body interactions in the CeO(111) oxygen vacancy structure with statistical learning and cluster expansion.

Oxygen vacancies (V's) are of paramount importance in influencing the properties and applications of ceria (CeO). Yet, comprehending the distribution and nature of V's poses a significant challenge due to the vast number of electronic configurations and intricate many-body interactions among V's and polarons (Ce ions). In this study, we established a cluster expansion model based on first-principles calculations and statistical learning to decouple the interactions among the Ce ions and V's, thereby circumventing the limitations associated with sampling electronic configurations.

An engineered adeno-associated virus mediates efficient blood-brain barrier penetration with enhanced neurotropism and reduced hepatotropism.

The blood-brain barrier (BBB) is a formidable barrier that restricts the entry of substances into the brain, complicating the study of brain function and the treatment of neurological conditions. Traditional methods of delivering genes from the periphery to the central nervous system (CNS) using adeno-associated viruses (AAVs) often require high doses, which can trigger immune responses and hepatotoxicity. Here, we developed a new AAV variant named AAVhu.

As the quality of life continues to improve globally, there is an increasing demand for nutritious and high-quality food products. Peanut butter, a widely consumed and nutritionally valuable product, must meet stringent quality standards and exhibit excellent stability to satisfy consumer expectations and maintain its competitive position in the market. However, its high fat content, particularly unsaturated fatty acids, makes it highly susceptible to quality deterioration during storage.

Variations in the Impact of Gingerols' Conversion to Shogaols on the Properties of Corn Starch with Different Amylose Contents.

The polyphenol-starch complex has become a hot research topic since it is evident that this modification method can alter the physicochemical properties of starch as well as improve its nutritional value. This work aimed to evaluate the effect of ginger polyphenol gingerols (GNs) and shogaols (SNs) on the structure of starch with different amylose content (WCS, CS, G56, G80). Textural and rheological results indicated that GNs and SNs had more pronounced inhibitory retrogradation effects for relative low-level amylose starches (WCS and CS) compared to relative high-level amylose starches (G56 and G80).
