Biowaste-Derived, Highly Efficient, Reusable Carbon Nanospheres for Speedy Removal of Organic Dyes from Aqueous Solutions

open access: yesMolecules, 2022
The current work explores the adsorptive efficiency of carbon nanospheres (CNSs) derived from oil palm leaves (OPL) that are a source of biowaste. CNSs were synthesized at 400, 600, 800 and 1000 °C, and those obtained at 1000 °C demonstrated maximum ...

Sperm miR‐15a and miR‐29b are associated with bull fertility

open access: yesAndrologia, 2020
MicroRNAs modulate male fertility by regulating gene expression. In this study, dynamics of sperm miR‐15a, miR‐29b and miR‐34a from high fertility (HF) and low fertility (LF) bulls using RT‐qPCR were evaluated.
