The Effects of Paeonia lactiflora Pall. and Astragalus Membranaceus Single Extracts on Bone Metabolic Profile in Ovariectomized Mice

Clinical and Experimental Obstetrics & Gynecology
Background: Metabolic bone disease, associated with estrogen deficiency, is common condition in postmenopausal women. Paeonia lactiflora Pall. (PL) and Astragalus membranaceus (AM) have been known to have estrogenic activity and to improve postmenopausal

Echolocation repetition rate as a proxy to monitor population structure and dynamics of sperm whales

Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 827-840, December 2022., 2022
Passive acoustic monitoring is an essential method for studying the ecology of endangered sperm whales. We present a novel approach based on their sexual body size dimorphism to monitor population structure and dynamics by using the time interval between echolocation clicks (ICI) as a proxy for body length. Our results suggest that ICI can be used as a

BMP4 regulates asymmetric Pkd2 distribution in mouse nodal immotile cilia and ciliary mechanosensing required for left–right determination

Developmental Dynamics, EarlyView.
Abstract Background Mouse nodal immotile cilia mechanically sense the bending direction for left–right (L–R) determination and activate the left‐side‐specific signaling cascade, leading to increased Nodal activity. Asymmetric distribution of Pkd2, a crucial channel for L–R determination, on immotile cilia has been reported recently. However, the causal

In-vitro application of pentoxifylline preserved ultrastructure of spermatozoa after vitrification in asthenozoospermic patients [PDF]

, 2017
PURPOSE: To evaluate the effect of in vitro application of pentoxifylline (PX) on sperm parameters and ultrastructure after vitrification in asthenozoospermic patients. MATERIALS AND METHODS: A total of 30 asthenozoospermic semen samples (aged 25-45

SHMC-Net: A Mask-guided Feature Fusion Network for Sperm Head Morphology Classification [PDF]

arXiv
Male infertility accounts for about one-third of global infertility cases. Manual assessment of sperm abnormalities through head morphology analysis encounters issues of observer variability and diagnostic discrepancies among experts. Its alternative, Computer-Assisted Semen Analysis (CASA), suffers from low-quality sperm images, small datasets, and ...
