[Assessment of the lagging effect of vegetation response and loss probability in the Pearl River basin under drought stress].

We quantified the lag time of vegetation response to drought in the Pearl River basin (PRB) based on the standardized precipitation evapotranspiration index (SPEI) and normalized difference vegetation index (NDVI), and constructed a vegetation loss probability model under drought stress based on the Bayesian theory and two-dimensional joint distribution. We further quantitatively evaluated the spatial variations of loss probability of four vegetation types (evergreen broadleaf forest, mixed forest, grassland, and cropland) under different drought intensities. The results showed that the drought risk in eastern West River, the upper reaches of North River and East River, and southern Pearl River Delta was obviously higher than that in other regions during 1982-2020.

A metabolomic approach to study triptolide-induced ovarian damage in rats.

Triptolide (TP) is the major active ingredient of Tripterygium wilfordii Hook, a traditional Chinese herb that possesses various pharmacological activities and has been used to treat autoimmune and inflammatory diseases for thousands of years. However, the clinical application of TP is limited due to its multiorgan toxicity, and in particular, its negative impact on female fertility. To date, the specific toxic mechanisms on reproduction induced by TP remain unclear.

Can Priming Legal Consequences and the Concept of Honesty Decrease Cheating During Examinations?

Cheating on exams is a very common phenomenon that causes great harm. Various measures, such as chastisement and direct punishment, have been employed to reduce cheating. Previous studies have found that increasing punishment and activating "self-concept maintenance" can reduce this behavior.
