BackgroundAs one of the most aging populations in the world, China has experienced a continuous increase in the disease burden of Alzheimer’s Disease (AD) and other dementia (ADRD). This study aims to analyze the trends in prevalence and mortality rates of AD and related dementia in China from 1990...

Introduction:Ginsenoside Rh3 (GRh3), a rare ginsenoside, demonstrates diverse pharmacological activities in vitro; however, the lack of pharmacokinetic and tissue distribution data has limited its translation to in vivo applications. This study aimed to develop and validate a novel liquid chromatogr...

STYK1 (Serine/threonine/tyrosine kinase 1), a member of the receptor tyrosine kinase family, exhibits tumorigenicity in many types of cancers. Our study reveals the important role played by STYK1 in nasopharyngeal carcinoma. STYK1 is upregulated in nasopharyngeal carcinoma tissues compared with para...

The West Liaohe Plain is located in the eastern Inner Mongolia, known as the golden maize belt in China, where maize acreage has continued to rise in recent years. Water is the main limiting factor for maize production in the region, therefore, this study calculated the effect of maize sowing area c...

Cylindrical targets have a high utilization rate, but are difficult to manufacture. A large hollow ITTO segment with thin walls was prepared by cold isostatic pressure and two-stage sintering. The fabrication process yielded a segment with an outer diameter of 153 mm, an inner diameter of 135 mm, an...

Maize (Zea mays), as a staple food and an important industrial raw material, has been widely cultivated for centuries especially by smallholder farmers. Maize lethal necrosis disease (MLND) is a serious disease infecting maize, which caused devastating damage in the African region recently. MLND is...

The aging of oil-impregnated paper (OIP) insulation is one of the key factors influencing the service life of oil-immersed current transformers. Frequency domain spectroscopy (FDS), supported by mathematical models or simulation methods, is commonly used to evaluate insulation conditions. However, t...

The mechanisms of chemoreception in fig wasps (Hymenoptera, Agaonidae) are of primary importance in their co-evolutionary relationship with the fig trees they pollinate. As the supplementary receptors to odorant receptors (ORs) and gustatory receptors (GRs) in insects, we compare the evolutionary ch...

The gene expression and activity of (+)-δ-cadinene synthase during cotton development and in response to stress, as well as the spatial and temporal pattern of sesquiterpene biosynthesis, constitute one of chemical defense mechanisms in cotton plants. In order to explore the effects of omethoate on...

Ergopeptines or their derivatives are widely used for treating neurodegenerative and cerebrovascular diseases. The nonribosomal peptide synthetase—d-lysergyl peptide synthetase A (LPSA) determines ergopeptine formation but the detailed mechanism remains to be elucidated. Here, we characterized two L...

As pesticide residues in bayberry has raised serious concern from the public in China, a monitoring survey was carried out during 2013–2014 and 157 samples were analyzed in total. Twenty-three pesticides were detected among the 44 pesticides analyzed and at least one pesticide was detected in 63% of...

To evaluate the feasibility of 60Co irradiation for rapid aging of SSATB, this study employed fresh SSATB (CK) as a benchmark while subjecting test samples to irradiation for 12 h, 24 h, 36 h, and 48 h, natural aging for five years (5Y) as a contrast. Three analytical platforms, E-nose, HS-SPME-GC–M...

IntroductionIn recent years, interest in the brain-gut axis has increased, and interactions between the brain and the gut may be closely related to recurrent clinical symptoms in patients with inflammatory bowel disease. We aimed to investigate the changes in white matter microstructure in the brain...

The reuse of treated wastewater in agricultural systems could partially help alleviate water resource shortages in developing countries. Treated wastewater differs from fresh water in that it has higher concentrations of salts, Escherichia coli and presence of dissolved organic matter, and inorganic...
