INTRODUCTION Transurethral resection syndrome is an uncommon but potentially life threatening complication. Various irrigating solutions have been used, normal saline being the most physiological. The recent availability of bipolar cautery has permitted the use of normal saline irrigation. MATERIAL AND METHODS In a randomized prospective study, we compared the safety and efficacy of bipolar c...

Electrosurgery is the most commonly used and misunderstood technology by all surgical and medical disciplines. A lack of basic knowledge or ignorance of principles of electrosurgery and equipment among obstetricians and gynecologists is reported. As a result, thermal injuries during laparoscopic electrosurgery occur, which frequently lead to significant morbidity and mortality and medicolegal a...

BACKGROUND In the fission yeast Schizosaccharomyces pombe, cell growth takes place exclusively at both ends of the cylindrical cell. During this highly polarized growth, microtubules are responsible for the placement of the cell-end marker proteins, the Tea1-Tea4/Wsh3 complex, which recruits the Pom1 DYRK-family protein kinase. Pom1 is required for proper positioning of growth sites, and the De...

PURPOSE To characterize the diffusion coefficient of human blood for accurate results in intravoxel incoherent motion imaging. METHODS Diffusion-weighted MRI of blood samples from 10 healthy volunteers was acquired with a single-shot echo-planar-imaging sequence at body temperature. Effects of gradient profile (monopolar or flow-compensated), diffusion time (40-100 ms), and echo time (60-200 ...

Soft-field imaging methods, such as Optical Tomography (OT) and Electrical Impedance Tomography (EIT) have significant potential for medical imaging as they are non-invasive, portable and inexpensive. Possible clinical applications include epilepsy monitoring, cerebral stroke differentiation and screening for breast cancer. Recent advances in data acquisition instrumentation and image reconstru...
