Pregnenolonyl-α-glucoside exhibits marked anti-cancer and CYP17A1 enzymatic inhibitory activities.

We report here that pregnenolonyl-α-glucoside (2), a steryl glycoside synthesized directly from pregnenolone and glucose via a consecutive multienzyme-catalyzed process, exhibits marked dose-dependent cytotoxic activity against HT29, AGS, and ES-2 cells with IC50 values of 23.5 to 50.9 μM.

Deep venous thrombosis: comparison of indirect multidetector CT venography and sonography of lower extremities in 26 patients.

Objective: To compare the accuracy of indirect mutidetector row computed tomographic (MDCT) venography with lower extremity venous sonography for the diagnosis of femoropopliteal deep venous thrombosis (DVT), and to determine the frequency and location of DVT at MDCT venography.

Materials And Methods: Twenty-six consecutive patients suspected of having pulmonary embolism (PE) underwent both combined MDCT venography and MDCT pulmonary angiography and lower extremity venous sonography. Indirect MDCT venography was acquired from the upper calves to the mid-abdomen following MDCT pulmonary angiography.

Combined computed tomography venography and pulmonary angiography for the diagnosis PE and DVT in the ED.

The purpose of this study is to evaluate the usefulness of combined computed tomography venography and pulmonary angiography (CTVPA) in the diagnosis of venous thromboembolic (VTE) disease in the emergency department (ED). CTVPA images and clinical data of 73 nonselected patients with suspected pulmonary embolism (PE) and/or deep venous thrombosis (DVT) were retrospectively assessed. CTVPA correctly identified 33 of 34 patients with VTE disease, including 7 patients with PE alone, 11 patients with DVT alone, and 16 patients with both PE and DVT.
