Regulation of catalase activity variation of tea tree (Camellia sinensis)
Catalase (CAT) is a protective enzyme responsible for the degradation of hydrogen peroxide before it damages the cellular components. All aerobic organisms and many anaerobic organisms possess it in virtually.

Planetary Nebulae as Probes of Stellar Populations [PDF]
Planetary nebulae (PNe) have the potential to revolutionize our understanding of extragalactic stellar populations. Indeed, in many systems, bright PNe are the only individual objects identifiable from the ground, and, even more often, they are the only ...

Screening of wheat grains enriched with wall-bound phenolic compounds
Phenolic compounds are dominant antioxidant factors in whole grains and are essential quality traits in future breeding programs. We proposed a robust set of methods for extraction, screening, and quantitative analysis of soluble and wall-bound (WB ...

The high-field polar RX J1007.5-2017 [PDF]
We report optical and X-ray observations of the high-field polar RXJ1007.5-2017 performed between 1990 and 2012. It has an orbital period of 208.60 min determined from the ellipsoidal modulation of the secondary star in an extended low state.
