Structural characteristics of polysaccharide isolated from Potentilla anserina L. and its mitigating effect on Zearalenone-induced oxidative stress in Sertoli cells.

The present study aims to characterize the structural features of a natural polysaccharide called PAP-1b extracted from the roots of Potentilla anserina L. and to evaluate its antioxidant activity. Structural characterization indicated that PAP-1b with a molecular weight of 1.

Unsupervised distribution-aware keypoints generation from 3D point clouds.

Keypoints extraction from 3D objects is a fundamental task in point cloud processing. The ideal keypoints should be an ordered and well-aligned set of points that effectively reflect the shape and structure of the object. To this end, this paper proposes an unsupervised 3D point cloud keypoints generation network with the consideration of the probability distribution of keypoints and spatial distribution among keypoints.

Evaluation of the Genetic Diversity and Population Structure of Four Native Pig Populations in Gansu Province.

Indigenous pig populations, including Bamei pigs (BM), Hezuo pigs (HZ), Huixian Qingni Black pigs (HX), and Minxian Black pigs (MX) in Gansu Province, live in a particular climate and a relatively closed geographical environment. These local pig breeds are characterized by excellent characteristics (e.g.

Regulatory Effects of the Gene in the Testis on Puberty and Reproduction in Hezuo and Landrance Boars.

Kisspeptin, a neuropeptide encoded by the gene, combines with its receptor Kiss1R to regulate the onset of puberty and male fertility by the hypothalamic-pituitary-gonadal axis. However, little is known regarding the expression signatures and molecular functions of in the testis. H&E staining revealed that well-arranged spermatogonia, spermatocytes, round and elongated spermatids, and spermatozoa, were observed in 4-, 6-, and 8-month-old testes compared to 1- and 3-month-old testes of Hezuo pigs; however, these were not observed in Landrance until 6 months.

Photocatalytic Hydrogen Production by RGO/ZnInS under Visible Light with Simultaneous Organic Amine Degradation.

In this work, the study of photocatalytic hydrogen production by RGO/ZnInS with simultaneous degradation of organic amines was carried out in the presence of organic amines in wastewater as the sacrificial agents. The effects of several factors, such as organic amine types, pH value, catalyst concentration, organic amine concentration, and sunlight source, on the photocatalytic activity of RGO/ZnInS for H production were investigated. At the same time, its performance of degrading organic amines during H production was also examined.
