Background: Forests in nearly all regions worldwide are affected by invasions of non-native bark beetles. Hylurgus ligniperda (Fabricius) is a globally invasive bark beetle that stealthily jeopardizes pine health and spreads worldwide insidiously. The worldwide occurrence of Hylurgus ligniperda challenges trade in pine logs or wooden materials.

Hylurgus ligniperda (Fabricius) is an important pest that attacks Pinus species in China. It impacts the vitality of local pine vegetation, reduces the ability to prevent windbreak and sand fixation, and causes ecological loss. MaxEnt and ArcGIS are used to predict and analyze the changes in suitable distribution areas of H.

Natural products, with their extensive chemical diversity, distinctive biological activities, and vast reservoirs, provide a robust foundation for advancing cancer therapeutics. A comprehensive phytochemical investigation of the skins from Bufo bufo gargarizans afforded two new bufadienolide derivatives identified as bufalactamides A and B (1-2), along with six known compounds: argentinogenin (3), desacetylcinobufagin (4), desacetylcinobufaginol (5), cinobufaginol (6), bufalin (7) and gamabufalin (8). The structural elucidation of these compounds was meticulously carried out by analyses of spectroscopic data (1D and 2D NMR, HR-ESIMS), and comparison with the literature data.

Article Synopsis
  • The rapid growth of digital health presents opportunities for elderly patients with chronic diseases, but a digital divide limits their use of digital health technologies (DHTs).
  • The study examined factors affecting DHT adoption among older adults, extending the UTAUT theory to include technology anxiety and demographic predictors.
  • Findings suggest that improving facilitating conditions and usage experiences, along with targeted education and support, can reduce technology anxiety and enhance the acceptance of DHTs in this vulnerable group.

Background: Hylurgus ligniperda, a major international forestry quarantine pest, was recently found to have invaded and posed a serious threat to the Pinus forests of the Jiaodong Peninsula in China. Continuous monitoring and vigilance of the early population is imperative, and rapid molecular detection technology is urgently needed. We focused on developing a single-gene-based species-specific PCR (SS-PCR) method.

The immunogenicity of transplanted allogeneic cells and tissues is a major hurdle to the advancement of cell therapies. Here we show that the overexpression of eight immunomodulatory transgenes (Pdl1, Cd200, Cd47, H2-M3, Fasl, Serpinb9, Ccl21 and Mfge8) in mouse embryonic stem cells (mESCs) is sufficient to immunologically 'cloak' the cells as well as tissues derived from them, allowing their survival for months in outbred and allogeneic inbred recipients. Overexpression of the human orthologues of these genes in human ESCs abolished the activation of allogeneic human peripheral blood mononuclear cells and their inflammatory responses.

Article Synopsis
  • * Researchers engineered mouse embryonic stem cells to produce "neutralizing biologics" (nBios) that effectively neutralize SARS-CoV-2 and can be transplanted to provide long-term immune protection.
  • * The study demonstrates that these genetically modified cells can secrete potent nBios over time, suggesting their potential for developing safe, long-lasting cell therapies for viral immunity in the future.

Article Synopsis
  • * A new molecular technique called RPA-LFD combines recombinase polymerase amplification and a lateral flow dipstick, allowing for quick and accurate identification of the beetle with minimal DNA requirements (as little as 10-3 ng).
  • * This method is easy to perform without specialized equipment, can be done at varied temperatures (30 to 50 °C), and enables detection of A. mali in just 30 minutes, making it highly useful for pest management and on-site diagnosis in various contexts.

Background: Retinitis pigmentosa (RP) is an inherited retinal disease that results in photoreceptor degeneration, leading to severe vision loss or blindness. Due to its genetic heterogeneity, developing a new gene therapy to correct every genetic mutation contributing to its progression is infeasible. Photoreceptor transplantation can be harnessed to restore vision; however, this approach is limited by poor cell survival and synaptic integration into the neural retina.

Developing industrial-grade electroreduction of CO to produce formate (HCOO)/formic acid (HCOOH) depends on highly active electrocatalysts. However, structural changes due to the inevitable self-reduction of catalysts result in severe long-term stability issues at industrial-grade current density. Herein, linear cyanamide anion ([NCN])-constructed indium cyanamide nanoparticles (InNCN) were investigated for CO reduction to HCOO with a Faradaic efficiency of up to 96% under a partial current density () of 250 mA cm.

This study explored the effect of daily loneliness on social media use and the mediating role of fear of missing out (FoMO). A total of 106 college students participated in a 2-week experience sampling study, yielding 1194 data points. The results showed that daily loneliness predicted social media use via FoMO.

Background: Intervertebral disc degeneration (IDD) is a pathological process that occurs during the natural aging of intervertebral discs. Accumulating evidence suggests that noncoding RNAs (ncRNAs), including microRNAs and long ncRNAs (lncRNAs), participate in the pathogenesis and development of IDD. Herein, we examined the role of lncRNA MAGI2-AS3 in the pathogenic mechanism of IDD.

Cobalt-based spinel oxides are considered potential candidates for the oxygen evolution reaction (OER) due to their abundant valence changes and promising electrochemical activity, but their low intrinsic activity hinders their practical applications. Herein, we synthesize a series of CoCeMO (M = Zn, Ni, Ru, Er, Mg, Mn, Sn) derived from CoCeM coordination-driven self-assembled aggregates (CDSAAs) using a general ion exchange and subsequent calcination method. Interestingly, CoCeMO exhibit different morphologies from porous nanospheres, particle-stacked nanospheres, to hollow nanospheres as the third metal element is altered.

Progressive infarction (PI) is common in small subcortical infarction and may lead to a poor outcome. The purpose of our study is to identify neuroimaging predictors for PI. From April 2017 to December 2020, we enrolled 86 patients with an anterior circulation subcortical infarction within 48 h after onset.

is economically important as a highly specific parasitoid of the invasive pest which was introduced into the Euro-Asia region in the last decade. Despite being a critical and specific parasitoid of the invasive pest and its use as an effective biocontrol agent, the absence of sequence information from have limited its genetic applications for pest management in forests. Mitochondrial (mt) genomes generally contain abundant nucleotide information and thus are helpful for understanding species history.

Normally, an obvious antagonism exists between pain and itch. In normal conditions, painful stimuli suppress itch sensation, whereas pain killers often generate itch. Although pain and itch are mediated by separate pathways under normal conditions, most chemicals are not highly specific to one sensation in chronic pathologic conditions.

Podocyte function is tightly linked to the complex organization of its cytoskeleton and adhesion to the underlying glomerular basement membrane. Adhesion of cultured podocytes to a variety of substrates is reported to correlate with podocyte health. To identify novel genes that are important for podocyte function, we designed an in vitro genetic screen based on podocyte adhesion to plates coated with either fibronectin or soluble Fms-like tyrosine kinase-1 (sFLT1)/Fc.

Diabetic nephropathy is a leading cause of end-stage kidney failure. Reduced angiopoietin-TIE2 receptor tyrosine kinase signaling in the vasculature leads to increased vascular permeability, inflammation, and endothelial cell loss and is associated with the development of diabetic complications. Here, we identified a mechanism to explain how TIE2 signaling is attenuated in diabetic animals.
