Ensemble-Based Assimilation of Satellite All-Sky Microwave Radiances Improves Intensity and Rainfall Predictions for Hurricane Harvey (2017).

Ensemble-based data assimilation of radar observations across inner-core regions of tropical cyclones (TCs) in tandem with satellite all-sky infrared (IR) radiances across the TC domain improves TC track and intensity forecasts. This study further investigates potential enhancements in TC track, intensity, and rainfall forecasts via assimilation of all-sky microwave (MW) radiances using Hurricane Harvey (2017) as an example. Assimilating Global Precipitation Measurement constellation all-sky MW radiances in addition to GOES-16 all-sky IR radiances reduces the forecast errors in the TC track, rapid intensification (RI), and peak intensity compared to assimilating all-sky IR radiances alone, including a 24-hr increase in forecast lead-time for RI.

Effect of short-term administration of dexamethasone on canine antral gastrin gene expression.

The acute effect of corticosteroids on the release and biosynthesis of gastrin still remains unclear. We report the effect of short-term administration of dexamethasone on the antral gastrin gene expression and gastrin levels in 6 dogs, which were treated with dexamethasone (1.5 mg/kg, i.

Induction of rat brain tumor with xenotropic pseudotype murine sarcoma virus.

The oncogenicity of xenotropic pseudotype Kirsten murine sarcoma virus (MSV) was investigated in Sprague-Dawley rats. When fetal or newborn rats were inoculated intracerebrally with xenotropic pseudotype MSV, brain tumors developed after about one month. Tumors were induced both in the cerebrum and the cerebellum.
