(Asteraceae), a new species from Xizang (Tibet), China.

, a new species of Asteraceae from the Xizang (Tibet) Autonomous Region of China, is described and illustrated here. Morphologically, it is most similar to but can be distinguished by the combination of monoecious and dioecious individuals, involucral bracts arranged in 3-5 series (with outer series herbaceous and middle to inner series membranous), fimbriate apices on female florets, rough-edged lobes on male florets, and achenes lacking costae. Phylogenetic analyses further support the separation of this new species from related taxa.

Cell Culture of a Swine Genotype 4 Hepatitis E Virus Strain.

HEV infection has become a global health concern. The study of HEV pathogenicity has been hindered by the lack of a suitable in vitro culture system. In the present research, we systematic demonstration of efficient replication of swine GT4 HEV in A549 cells, Huh-7 cells, and HepG2/C3A cell lines.

The bta-miR-22-3p can alleviate LPS-induced inflammatory response in yak endometrial epithelial cells by targeting KSR2.

Bovine endometritis is a common reproductive system disease in dairy cows that leads to decreased milk production and reproductive performance, causing significant economic losses for farmers. Research has shown that microRNAs (miRNAs) play a significant role in regulating the expression of biological genes and are closely related to the occurrence of inflammation, including bta-miR-22-3p. However, the specific molecular mechanisms by which miRNAs regulate bovine endometritis remain unclear.

Effect of cooking methods on flavor profiles of Xuanwei Ham: Analytical insights into aromatic composition and sensory attributes.

To examine flavor variations in Xuanwei ham due to different cooking methods, we selected one-year cured Xuanwei ham and applied four techniques: dry frying (DF), baking (BA), steaming (ST), and boiling (BO). Organoleptic evaluation revealed ST received the highest overall sensory score. High-performance liquid chromatography (HPLC) revealed that the total nucleotide content was significantly different ( < 0.

A Fruit-Expressed MYB Transcription Factor Regulates Anthocyanin Biosynthesis in .

Anthocyanins are water-soluble flavonoid pigments that play a crucial role in plant growth and metabolism. They serve as attractants for animals by providing plants with red, blue, and purple pigments, facilitating pollination and seed dispersal. The fruits of solanaceous plants, tomato () and eggplant (), primarily accumulate anthocyanins in the fruit peels, while the ripe fruits of () have a dark purple flesh due to anthocyanin accumulation.

Dracotangusions A and B, two new sesquiterpenes from Maxim. with anti-inflammatory activity.

Two new guaiane sesquiterpenoids were isolated from the dried aerial parts of Maxim., named as dracotangusions A () and B (), together with four known sesquiterpenoids, which were identified as Curcumenone (), (4Z,7Z,9Z)-11-Hydroxy-4,7,9-germacratriene-1,6-dione (), Kobusone (), and (1S,10S), (4S, 5S)-(+)-germacrone-1(10)-4-diepoxide (). The structures of isolates were determined by UV, IR, HR-ESI-MS, and NMR analysis.

Characteristics of Atmospheric Reactive Nitrogen Deposition in Nyingchi City.

Atmospheric reactive nitrogen (N) deposition has been proven to be an important nutrient input from external environments to forest ecosystems. However, the magnitude of atmospheric N deposition in the Tibetan region of China is not well known. In this study, multi-year (between 2005 and 2016) measurements of dry and wet N deposition were carried out in Nyingchi (NC) city, southeastern Tibet.
