Silicon‐Based Agent Attenuates Age‐Related Spermatogenesis Disorder

International Journal of Urology, EarlyView.
ABSTRACT Objectives The progressive decline in birth rates due to delayed marriage has become a significant issue in developed countries, with male spermatogenetic capabilities gradually declining with age. This study evaluated the effectiveness of a silicon‐based agent (Si‐based) that efficiently generates hydrogen in the body to improve spermatogenic

An Increase in Male Recombination Rate With Age in Dairy Cattle Is Heritable and Polygenic

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Meiotic recombination is an essential process for shuffling genetic diversity in sexually reproducing organisms, can vary within and between individuals in response to intrinsic and extrinsic factors, and can be heritable. Interestingly, recombination rate has been found to vary with age in some species, but to date, there have been no ...

Reproductive biology of invasive grass carp (Ctenopharyngodon idella) in two North American systems

Journal of Fish Biology, EarlyView.
Abstract Grass carp (Ctenopharyngodon idella) are nonnative, herbivorous freshwater fish that represent an ecological threat in North American waters. However, data are limited on reproductive biology specific to wild populations in midwestern North America, despite recent concern for grass carp establishment within the Great Lakes.

Non‐invasive ultrasound measurements for determination of hepato‐somatic index in Greenland halibut (Reinhardtius hippoglossoides)

Journal of Fish Biology, EarlyView.
Abstract Hepato‐somatic index (HSI) is widely used to indicate fish body condition and level of energy reserves related to feeding/physiology and reproduction. HSI is traditionally obtained by dissection and measurement of liver mass versus body mass, but ultrasound technology may provide a minor invasive method to obtain liver dimensions to estimate ...
