The middle reaches of the Yellow River (MRYR) in China are some of the most severely eroded areas in the world. Knowledge of the changes in sediment yield in the MRYR is of great significance for understanding the impact of human activities on soil erosion and sediment transport. Using data from the MRYR and 13 sub-basins, this study aims to evaluate the actual contributions of human activities to sediment yields and to examine whether the widely used Mann-Kendall test has underestimated this contribution.

Skin precursor-derived Schwann cells have demonstrated an accelerated in vivo pre-vascularization of tissue-engineered nerves. Furthermore, extracellular vesicles from skin precursor-derived Schwann cells (SKP-SC-EVs) show the potential in aiding peripheral nerve regeneration.

The aim of current study was to elucidate the role of diurnal temperature fluctuation and exercise in the development of HAPE and establish a reliable experimental rat model. Male SPF Wistar rats were assigned to control group (1400 m, 25 °C) and five model groups: Model Ⅰ group (6000 m, 25 °C), Model Ⅱ group (6000 m, 2 °C), Model Ⅲ group (6000 m, 12 °C/2 °C light/dark cycle), Model IV group (6000 m, 2 °C, and exercise) and Model V group (6000 m, 12 °C/2 °C light/dark cycle, and exercise).

However, it is a recently discovered protein with largely unexplored expression patterns and biological functions. Bioinformatics analyses and immunohistochemistry staining were assessed to detect both mRNA and protein levels of ZNF131 in NSCLC specimens and cell lines.

Yet, excessive PA doping causes a decline in mechanical strength, which in turn affects the cell performance. We utilize a strategy that integrates elevated PA absorption, increased mechanical strength, and enhanced PA retention.

However, almost all of them with high efficiency are Pb/Cd-based toxic heavy metal perovskites, which seriously limits their commercial applications. To address the dual needs of high efficiency and environmental protection, this study proposes to incorporate Mn into the environmentally friendly perovskite CsEuX (X = Cl/Br), and further increases PLQY to 96.

Therefore, monitoring patients' fatigue status promptly, recognizing highly fatigued patients, and providing physical and psychological support are essential for improving their quality of life. As a positive psychological trait, self-efficacy can influence the level of fatigue in patients undergoing radiotherapy for esophageal cancer.

Pinus massoniana pollen polysaccharide (PPPS) is a natural polymer with known biological activities, including anti-inflammatory, antioxidant, and antiviral properties. In this study, we aimed to investigate the impact of PPPS on SMI, myocardial enzyme levels, pathological changes, oxidative stress, cell apoptosis, and related signaling pathways in LPS-induced SMI models were observed by hematoxylin-eosin (HE) staining, immunohistochemical (IHC) staining, qPCR, Western blot analysis, with a particular focus on anti-inflammatory effects of PPPS.

In an earlier analysis of the SURMOUNT-1 trial, tirzepatide was shown to provide substantial and sustained reductions in body weight in persons with obesity over a 72-week period. Here, we report the 3-year safety outcomes with tirzepatide and its efficacy in reducing weight and delaying progression to type 2 diabetes in persons with both obesity and prediabetes.

Objective: Radioactive intestinal injury is a common complication during radiotherapy of tumors. The aim of this study is to observe the effect of ionizing radiation on short-term changes in intestinal bile acids and to investigate the radioprotective effect of bile acids on intestinal cells.
Methods: A rat model of small intestinal injury was constructed by exposing the abdomen of the rats to daily irradiation at 2 Gy for 4 d in succession.
Background: Hypnotherapy has a potential role in modulating attention bias to treat social anxiety disorder (SAD). This study aimed to verify whether hypnotherapy can reduce social anxiety by changing attentional bias. The primary objective of our study is to explore the influence of hypnosis on various aspects of attention processes, specifically focusing on how it affects attention bias and social anxiety.

Emerging single-cell and single-nucleus RNA sequencing (sc/snRNA-seq) technologies have become instrumental in unravelling cellular heterogeneity and characterizing molecular signatures at single-cell resolution. Single-cell T cell receptor sequencing (scTCR-seq) and single-cell B cell receptor sequencing (scBCR-seq) technologies provide unprecedented opportunities to explore the immune repertoire diversity.

However, current monotherapies, which target either the prevention of the inflammatory response or the attenuation of osteoclast (OC) formation, have limited efficacy due to the complexity of the bone immune system being overlooked. Herein, by means of modifying salmon calcitonin (sCT), a multifunctional nano-system (AuNDs-sCT) was designed to synergistically inhibit OC differentiation and reverse the inflammatory microenvironment against inflammatory osteolysis.

Unlabelled: Duck circovirus (DuCV) is widely recognized as a prominent virus in China's duck farming industry, known for its ability to cause persistent infections and significant immunosuppression, which can lead to an increased susceptibility to secondary infections, posing a significant threat to the duck industry. Moreover, clinical evidence also indicates the potential vertical transmission of the virus through duck embryos to subsequent generations of ducklings. However, the limited availability of suitable cell lines for cultivation of DuCV has hindered further investigation into the molecular mechanisms underlying its infection and pathogenicity.
