Land cover changes reduce dust aerosol concentrations in Northern China (2000-2020).

Dust aerosols significantly impact climate, human health, and ecosystems, but how land cover changes (LCC) influence dust concentrations remains unclear. Here, we applied the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) to assess the effects of LCC on dust aerosol concentrations from 2000 to 2020 in northern China. Based on land cover data derived from multi-source satellite remote sensing data, we conducted two simulation scenarios: one incorporating actual annual LCC and another assuming static land cover since 2000.

Characterization and Nutritional Intervention Effects of Type 5 Resistant Starch in Hyperlipidemia Mice.

Numerous reports have indicated that the type 3 resistant starch (RS3) derived from can regulate lipid metabolism. However, it remains unclear whether the type 5 resistant starch (RS5) exhibits similar effects. In this study, RS5 was prepared from native starch and lauric acid through a hydrothermal method for the first time, and its nutritional intervention effects on hyperlipidemia in mice were investigated.

Ultrasound-Guided Stellate Ganglion Block Combined with Pharmacological Treatment for Rosacea: A Report of Two Cases.

Rosacea is a chronic inflammatory disease primarily affecting the central facial region, significantly involving the facial blood vessels and the sebaceous gland units associated with hair follicles. The stellate ganglion block (SGB) technique can restore balance to autonomic nervous function by interrupting the impulse conduction of preganglionic and postganglionic sympathetic nerve fibers, thereby alleviating excessive peripheral blood vessel contraction, enhancing tissue blood supply, balancing hormone secretion, and modulating immune responses. SGB has demonstrated remarkable efficacy in treating various skin conditions affecting the head, face, and neck.

Inhibitory maturation and ocular dominance plasticity in mouse visual cortex require astrocyte CB1 receptors.

Endocannabinoids, signaling through the cannabinoid CB1 receptor (CB1R), regulate several forms of neuronal plasticity. CB1Rs in the developing primary visual cortex (V1) play a key role in the maturation of inhibitory circuits. Although CB1Rs were originally thought to reside mainly on presynaptic axon terminals, several studies have highlighted an unexpected role for astrocytic CB1Rs in endocannabinoid mediated plasticity.

Clinical Characteristics, Risk Factors, and Predictors of Nonobese Fatty Liver Disease: A Cross-Sectional Study.

Purpose: This study aimed to investigate the risk factors and predictors of non-obese fatty liver disease in the Chinese population.

Patients And Methods: A total of 6,014 adults who underwent physical examinations at Union Hospital of Huazhong University of Science and Technology from March 2019 to March 2023 were included in this study. Fatty liver disease was diagnosed based on at least two of the following criteria: diffuse echo patterns relative to the liver, spleen, and kidney; ultrasonic beam attenuation; and poor intrahepatic visual details.

Stress-induced premature senescence in high five cell cultures: a principal factor in cell-density effects.

The Baculovirus Expression Vector System (BEVS) is highly valued in vaccine development, protein engineering, and drug metabolism research due to its biosafety, operational convenience, rapid scalability, and capacity for self-assembling virus-like particles. However, increasing cell density at the time of inoculation severely compromises the production capacity of BEVS, resulting in the "cell density effect". This study aimed to explore the mechanisms of the cell density effect through time-series analysis of transcriptomes and proteomes, with the goal of overcoming or alleviating the decline in productivity caused by increased cell density.

Shape/properties collaborative intelligent manufacturing of artificial bone scaffold: structural design and additive manufacturing process.

Artificial bone graft stands out for avoiding limited source of autograft as well as susceptibility to infection of allograft, which makes it a current research hotspot in the field of bone defect repair. However, traditional design and manufacturing method cannot fabricate bone scaffold that well mimics complicated bone-like shape with interconnected porous structure and multiple properties akin to human natural bone. Additive manufacturing, which can achieve implant's tailored external contour and controllable fabrication of internal microporous structure, is able to form almost any shape of designed bone scaffold via layer-by-layer process.

Identifying the prognostic significance of mitophagy-associated genes in multiple myeloma: a novel risk model construction.

Multiple myeloma (MM) is a highly heterogeneous hematological malignancy that is currently incurable. Individualized therapeutic approaches based on accurate risk assessment are essential for improving the prognosis of MM patients. Nevertheless, current prognostic models for MM exhibit certain limitations and prognosis heterogeneity still an unresolved issue.

Therefore, this meta-analysis synthesized the effect of ginseng consumption on biomarkers of CVH in adults. A systematic search was performed in the databases of PubMed, Scopus, Web of Science, Embase, and the Cochrane Library through July 24, 2023 to screen out English-language randomized controlled trials (RCTs) evaluating the effects of ginseng consumption on body composition, blood pressure, vascular stiffness, lipid metabolism, glucose metabolism, insulin resistance, inflammatory cytokines, and adipocytokines in adults.

Lactonization of Diols Over Highly Efficient Metal-Based Catalysts.

Lactones has gained increasing attention in recent years due to wide application in polymer and pharmaceutical industries. Traditional synthetic methods of lactones often involve harsh operating temperature, use of strong alkalis and toxic oxidants. Therefore, lactonization of diols under milder conditions have been viewed as the most promising route for future commercialization.

Distribution of microplastics in Lanzhou section of the Yellow River: Characteristics, ecological risk assessment, and factors analysis.

Microplastic (MP) is an emerging pollutant that has attracted attention in the environmental field, and the research of MPs in freshwater systems needs to be strengthened. To characterize the MPs in surface water and sediments of the western urban river network, water and sediment samples were collected. The results showed that the abundance of MPs in the water body of the river network ranged from 7 to 172 n/L, whereas the abundance of MPs in the sediments ranged from 7 to 144 n/kg, and the average abundance in the dry season was significantly higher than that in the rainy season.

Compact Silicon-Arrayed Waveguide Gratings with Low Nonuniformity.

Array waveguide gratings (AWGs) have been widely used in multi-purpose and multi-functional integrated photonic devices for Microwave photonics (MWP) systems. In this paper, we compare the effect of output waveguide configurations on the performance of AWGs. The AWG with an output waveguide converging on the grating circle had larger crosstalk and lower nonuniformity.

Morphometric approaches to evolution and differentiation from archaeological sites: interpreting the archaeobotanical evidence from bronze age Haimenkou, Yunnan.

Unlabelled: Cannabis grains are frequently reported from archaeological sites in Asia, and hypothesized centers of origins are China and Central Asia. Chinese early cannabis remains are often interpreted as evidence of hemp fabric production, in line with early textual evidence describing ritualistic hemp cloth use and hemp cultivation as a grain crop. Modern measurements on cannabis varieties show distinct sizes between fibre or oil/fibre and psychoactive varieties, the former having larger seeds on average than the latter.
