Natural variation in the promoter of rice calcineurin B-like protein10 (OsCBL10) affects flooding tolerance during seed germination among rice subspecies.

Rice (Oryza sativa L.) has two ecotypes, upland and lowland rice, that have been observed to show different tolerance levels under flooding stress. In this study, two rice cultivars, upland (Up221, flooding-intolerant) and lowland (Low88, flooding-tolerant), were initially used to study their molecular mechanisms in response to flooding germination.

[Effect of electroacupuncture combined with cutaneous "tongluo" stimulation on gastric electrical rhythms and gastromucosal prostaglandin content in rats with chronic atrophic gastritis ].

Objective: To observe the effect of electroacupuncture (EA) combined with cutaneous "Tongluo" (meridian- dredging) stimulation on gastric electrical activities and gastromucosal prostaglandin (PG) level in rats with chronic atrophic gastritis (CAG), so as to investigate its mechanism underlying improvement of gastric function.

Methods: A total of 40 SD rats were randomly divided into blank control, CAG model, medication and combined therapy groups, with 10 rats being in each group. CAG model was established by.
