Dexmedetomidine as an Adjunct to Propofol in Patients Undergoing Elective Endoscopic Retrograde Cholangio-Pancreaticography - A Double-blind Randomized Controlled Study.

Background: Propofol is the drug of choice for procedural sedation. The addition of α agonist dexmedetomidine may improve the safety profile of the procedure by providing stable hemodynamics, better sedation quality, and decreasing the side effects of each drug during elective endoscopic retrograde cholangio-pancreaticography (ERCP).

Materials And Methods: Eighty patients aged between 18 and 60 years were distributed randomly into two groups.

Fat-only Dixon: how to use it in body MRI.

The Dixon method for fat/water separation is widely used to obtain uniform fat suppression using the water-only reconstruction. However, the fat-only reconstruction is potentially neglected in clinical practice, either not sent to the PACS or ignored upon imaging review. Fat-only Dixon provides a valuable tool for rapid screening for microscopic fat and problem-solving of lesions of interest.

Enhancing the Interpretation of Unenhanced Abdominopelvic CT.

Unenhanced abdominopelvic CT is frequently performed in patients who are critically ill or have contraindications to intravenous contrast. These cases can be challenging to interpret for the radiologist. Attention to CT physics and care in optimizing image viewing through techniques such as windowing can maximize diagnostic yield.

Rare Pancreatic Tumors.

Although pancreatic ductal adenocarcinoma is the most common type of pancreatic cancer, a variety of more rare benign and malignant tumors of the pancreas have been identified. Computed tomography (CT) and MR imaging are the primary modalities for further noninvasive characterization of these lesions. This review presents an approach to imaging of rare pancreatic tumors, including the CT and MR imaging technique, key imaging features and examples, and differential diagnosis.

MR Imaging of Vulvar and Vaginal Cancer.

Vulvar and vaginal cancer are uncommon gynecologic malignancies, most frequently diagnosed clinically. MR imaging is a powerful tool for local staging of these tumors and to detect posttreatment complications and recurrent disease. This review presents anatomic delineation of the female pelvis, pathology and staging of vulvar and vaginal cancer, MR imaging techniques of the pelvis, MR features of vulvar and vaginal cancer, and the differential diagnosis of potential mimickers.

Involvement of mitogen-activated protein kinase signalling in pearl millet-downy mildew interaction.

Mitogen-activated protein kinase (MAPK) cascade-mediated signalling is essential in the establishment of resistance towards pathogens. The present study compared MAPK activities in a compatible and incompatible interaction between pearl millet [Pennisetum glaucum (L.) R.
