Scopelophila cataractae is a rare moss that grows on copper-containing soils. S. cataractae protonema was grown on basal MS medium containing copper. A starch-degrading activity was detected in homogenates of the protonema, after successive extraction with phosphate buffer and buffer containing 3 M LiCl. Buffer-soluble extract (BS) and LiCl-soluble extract (LS) readily hydrolyzed amylopectin to...

sperm is produced by the testis and mature in the epididymis. for having a successful conception, the fertilizing sperm should have functional competent membranes, intact acrosome, functional mitochondria and an intact haploid genome. the effects of genetic and environmental factors result in sperm vulnerability to damage in the process of spermatogenesis and maturation. in recent years, the fe...

Glucose, a readily available biomass precursor is used for the production of carbon quantum dots (CQDs) via fast, efficient, and environmentally benign continuous hydrothermal flow synthesis (CHFS) process using supercritical water, an approach that can be scaled up industrialization, producing materials with enhanced properties. The water-soluble CQDs exhibit average particle size 2.3 ± 0.5 nm...
