BACKGROUND Rad (Ras associated with diabetes) GTPase is the prototypic member of a subfamily of Ras-related small G proteins. The aim of the present study was to define whether Rad plays an important role in mediating cardiac hypertrophy. METHODS AND RESULTS We document for the first time that levels of Rad mRNA and protein were decreased significantly in human failing hearts (n=10) compared ...

BACKGROUND AND OBJECTIVES Modern imaging techniques have increased the incidental detection of renal atherosclerotic disease (RAD). Because immune activation may hasten RAD progression, identifying cellular immune markers might provide clues to clinical activity. In this study, cellular immune markers were assessed in early RAD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Immune cell marker...

The new immunosuppressive agent, SDZ-RAD, and its analog rapamycin were examined for intestinal absorption, metabolism, and bioavailability in Wistar rats. Intestinal first-pass metabolism studies from rat jejunum showed that at 0.5 mg of SDZ-RAD/kg rat, 50% of the parent compound was metabolized in the intestinal mucosa, and this decreased to around 30% when SDZ-RAD was increased to 5.0 mg/kg ...

BACKGROUND The small GTPase Rad is a negative regulator of voltage-dependent L-type calcium channel current (ICaL); however, the effects of Rad ablation on cardiomyocyte function are unknown. The objective of this study is to test the hypothesis that Rad-depletion causes positive inotropic effects without inducing cardiac hypertrophy. METHODS AND RESULTS Ventricular myocytes from adult Rad(-/...

A recombinant adenovirus (rAd) expressing Cre recombinase derived from bacteriophage P1 has already been extensively used for the conditional gene activation and inactivation strategies in mammalian systems. In this study, we generated AxCAFLP, a rAd expressing FLP recombinase derived from Saccharomyces cerevisiae and carried out quantitative comparisons with Cre-expressing rAd in both in vitro...

Disorders of L-type Ca channels can cause severe cardiac arrhythmias. A subclass of small GTP-binding proteins, the RGK family, regulates L-type Ca current (ICa,L) in heterologous expression systems. Among these proteins, Rad (Ras associated with diabetes) is highly expressed in the heart, although its role in the heart remains unknown. Here we show that overexpression of dominant negative muta...

مگس مینوز سبزی و صیفی Liriomyza sativae Blanchard ، از مهم­ترین آفات ‌های گلخانه ای فضای باز، محسوب می شود. با توجه به توصیه کاربرد حشره­ کش تیوسیکلام جهت مدیریت آفت مزبور، در پژوهش حاضر، اثرات کشندگی زیرکشندگی(5/131:LC30، 1/87:LC20، 15/49:LC10 میلی گرم ماده موثره بر لیتر) حشره ­کش (اویسکت®SP50%) روی فراسنجه ­های زیستی این شرایط آزمایشگاهی مورد ارزیابی قرار گرفت. روش استفاده انجام آزمایش­ها غوط...

g t l n T o put into deserved perspective the contribution that Gleason and colleagues make in this issue of the Journal, theirs is one of the most extensive validation studies to date of reactive attachment disorder (RAD). The investigators sought to validate RAD with approaches derived from the classic 1970 article by Robins and Guze. The study focused primarily on four complementary aspects ...

PURPOSE The aim of the study was to retrospectively compare outcome and complications of prostate cancer patients treated with a curative and postoperative intent using a pretreatment defined NCCN classification. MATERIAL AND METHODS A total of 103 patients was treated curatively (RAD) and 94 postoperatively (POST-OP). The mean age was higher in the RAD group (72.6 years; range, 56.4-85.1) th...
