To investigate the response and the regulatory mechanism of common buckwheat starch, amylose, and amylopectin biosynthesis to P management strategies, field experiments were conducted in 2021 and 2022 using three phosphorus (P) levels. Results revealed that the application of 75 kg hm phosphate fertilizer significantly enhanced amylopectin and total starch content in common buckwheat, leading to improved grain weight and starch yield, and decreased starch granule size. The number of upregulated differentially expressed proteins induced by phosphate fertilizer increased with the application rate, with 56 proteins identified as shared differential proteins between different P levels, primarily associated with carbohydrate and amino acid metabolism.

High-resolution medical images are of critical significance to improve disease diagnosis. Limited by the camera and power of medical devices, medical images often have very low resolution. For example, wireless capsule endoscopes, often used to diagnose diseases of the small bowel, can only capture low-resolution endoscopic images.

Orf is an acute and highly contracted human and animal infection caused by orf virus (ORFV), which mainly affects sheep, goats, and other species. Clinically, opportunistic or conditional pathogens such as Staphylococcus aureus (S. aureus) are often detected in cases of orf, which greatly increases the risk of disease progression and clinical death.

Article Synopsis
  • * Researchers tested various additives—expansion agent (EA), shrinkage-reducing agent (SRA), and superabsorbent polymer (SAP)—to optimize hydration heat and shrinkage in concrete for different construction needs.
  • * While the expansion agent increases hydration and heat release, the shrinkage-reducing agent significantly lowers shrinkage by 79%, although it compromises strength; the study offers insights into effectively combining these components for better concrete performance in tunnel engineering.

Due to the movement expressiveness and privacy assurance of human skeleton data, 3D skeleton-based action inference is becoming popular in healthcare applications. These scenarios call for more advanced performance in application-specific algorithms and efficient hardware support. Warnings on health emergencies sensitive to response speed require low latency output and action early detection capabilities.

Orf is a widespread contagious epithelial viral disease found particularly in most sheep breeding countries in the world. Recently, an orf virus (ORFV) strain OV-HLJ05 was isolated from an outbreak in northeast China. Three genes of interest including ORFV011 (B2L), ORFV059 (F1L), and ORFV132 (VEGF) of ORFV, were recruited to identify and genetically characterize this newly isolated virus.

Nonpharmaceutical therapies such as exercise training and diet intervention are widely used for the treatment of insulin resistance (IR). Although the skeletal muscle is the major peripheral tissue of glucose metabolism under insulin stimulation, the mechanism underlying muscle IR is poorly understood. Using a high-fat diet-induced IR mouse model, we here show that NADPH oxidase 4 (Nox4) upregulation mediates the production of reactive oxygen species (ROS) that causes metabolic syndrome featuring IR.

Previously, we successfully prepared a monoclonal antibody (mAb) named 2E4, that directly recognizes the major envelope protein B2L of the orf virus (ORFV), but there is little information about its epitope. Here, we meticulously mapped the 2E4 epitope through combinatorial programs and identified the functional binding domain and a key amino acid residue. Briefly, the simulated epitope peptide closely resembles VDVQSKDKDADELR located at the N-terminus of B2L, strongly suggesting that the epitope is conformationally or spatially structure-dependent.
