Parametric-colored digital subtraction angiography using Tmax is almost a routine angiographic imaging procedure, currently. The current feasibility study is aimed to using the imaging to monitor treatment effects while embolizing indirect carotid-cavernous fistulas (CCF). ⋯ This postprocessing method does not require extra radiation exposure and contrast media. It facilitates real-time hemodyamic monitoring and may help determining the endpoint of embolization, which increases patient safety.

Fewer pauses and better chest compression quality are thought to improve overall survival following cardiac arrest. This study aimed to measure the outcomes of adult nontraumatic out-of-hospital cardiac arrests (OHCAs) treated with 5:1 compressions-to-ventilations (Thumper 1007) or continuous chest compressions with ventilation (Thumper 1008 CCV) mechanical cardiopulmonary resuscitation (CPR) within a specified period of time. ⋯ In an emergency department with short ambulance transport times, continuous chest compressions with ventilation through mechanical CPR showed improved outcomes, including ROSC and survival to hospital discharge, in an adult with OHCA. However, there are a variety of confounding influences that may affect the validity of conclusions that have been drawn.

The integrin β1 subunit and its downstream molecule focal adhesion kinase have been identified as critical molecules for the inhibition of postinfarction cardiac remodeling, ischemic cardiomyopathy, and heart failure. However, as a component of the integrin pathway, it is still unclear whether Dock180 (dedicator of cytokinesis 1) protein is expressed in the noninfarcted myocardium of the peri-infarct zones. In this study, experimental myocardial infarction (MI) and sham-operation (sham) models were established in Sprague Dawley rats and the expression of Dock180 protein in the myocardium of the sham group and in the noninfarcted myocardium of the peri-infarct zones of the MI group was detected by Western blot technique. ⋯ The Dock180 protein expression in the myocardium in the post-MI 12-week group was significantly higher than that in the postsham 12-week group (p = 0.019), in the postsham 24-hour group (p = 0.004), and in the post-MI 24-hour group (p = 0.040). We conclude that Dock180 protein is expressed in the myocardium in rats. Furthermore, its expression is significantly increased in the noninfarcted myocardium of the peri-infarct zones.

The role of estrogen in the growth and survival of ovarian cancer cells is controversial. In this study, we investigated the changes in cell-cycle regulatory proteins in ovarian cancer cell lines after estrogen treatment to explore the role of estrogen in ovarian cancers. ⋯ Although the ER-positive and ER-negative ovarian cancer cell lines were inhibited by estrogen, the influence of cell-cycle regulatory proteins was different between the two, suggesting that the inhibitory effect of estrogen on ovarian cancer cell lines might be mediated through different pathways.

The most common serious complication following acute ischemic stroke is pneumonia, which may increase mortality and worsen clinical outcomes. The purpose of this study was to investigate the predictors of 30-day mortality in patients with pneumonia following acute ischemic stroke. ⋯ Pneumonia after acute ischemic stroke is a severe complication. Once stroke-related pneumonia develops, neurologic assessment, CURB-65 score, and shock can be used to predict the ultimate prognosis.
