Clinical predictors of arterial extravasation, rebleeding and mortality following angiographic interventions in gastrointestinal bleeding.

Background And Aims: The aim of this study was to identify clinical and imaging predictors of arterial extravasation, post embolization rebleeding and 30-day mortality in gastrointestinal (GI) bleeding.

Method: This retrospective study included 114 patients who underwent angiography for upper or lower GI bleeding. Multivariate logistic regression was used to identify clinical and imaging predictors.

Dynamics of the rhomboid-like protein RHBDD2 expression in mouse retina and involvement of its human ortholog in retinitis pigmentosa.

The novel rhomboid-like protein RHBDD2 is distantly related to rhomboid proteins, a group of highly specialized membrane-bound proteases that catalyze regulated intramembrane proteolysis. In retina, RHBDD2 is expressed from embryonic stages to adulthood, and its levels show age-dependent changes. RHBDD2 is distinctly abundant in the perinuclear region of cells, and it localizes to their Golgi.
