Diffusion-weighted imaging(DWI), a functional imaging technique exploiting the Brownian motion of water molecules, is increasingly shown to have value in various oncological and non-oncological applications. Factors such as the ease of acquisition and ability to obtain functional information in the a.s.nce of intravenous contrast, especially in patients with abnormal renal function, have contributed to the growing interest in exploring clinical applications of DWI. In the liver, DWI demonstrates a gamut of clinical applications ranging from detecting focal liver lesions to monitoring response in patients undergoing serial follow-up after loco-regional and systemic therapies. DWI is a.s. being applied in the evaluation of diffuse liver diseases such as non-alcoholic fatty liver disease, hepatic fibrosis and cirrhosis. In this review, we intend to review the basic principles, technique, current clinical applications and future trends of DW-MRI in the liver.

BACKGROUND: This cross-sectional study aimed to a.s.ss the knowledge, attitude and anxiety pertaining to basic life support(BLs) and medical emergencies among interns in dental colleges of Mangalore city, Karnataka, ***: The study subjects comprised of interns who volunteered from the four dental colleges. The knowledge and attitude of interns were a.s.ssed using a 30-item questionnaire prepared based on the Basic Life support Manual from American Heart a.s.ciation and the anxiety of interns pertaining to BLs and medical emergencies were a.s.ssed using a.s.ate-Trait Anxiety Inventory(sTAI) Questionnaire.

A total of 123(67.21%) reported unavailability of professional training. The majority(180, 98.36%) felt the urgent need of training in basic life support procedures. a.s.ssment of stress showed a total of 27.1% participants to be above highstress level. Comparison of a.s.ssed knowledge and stress was found to be insignifi cant(P=0.983).CONCLUsION: There was an evident lack of knowledge pertaining to the management of medical emergencies among the interns. As oral health care providers moving out to the society, a focus should be placed on the training of dental interns with respect to Basic Life support procedures.

Novel barium tungstate/nitrogen-doped reduced graphene oxide-graphi- tic carbon nitride （BaWO4/NRGO-g-C3N4） nanocomposite has been synthesized by a.s.mple one-pot microwave technique. The synthesized nanocomposites are well characterized by diffraction, microscopic and spectroscopic techniques to study its crystal structure, elemental composition, morphological features and optical properties. The material prepared is tested for its performance as an electrocatalyst, photocatalyst and reduction catalyst. The nanocomposite catalyzed the photodegradation of methylene blue （MB） dye in 120 min, reduction of 4-nitro phenol （4-NP） to 4-amino phenol （4-AP） in 60 s, showed an impressive Tafel slope of 62 mV/dec for hydrogen evolution reaction （HER）. The observed results suggest that the nanocomposite acts as an efficient multifunctional catalyst. The reported approach provides fundamental insights which can be extended to other metal tungstate-based ternary composites for applications in the field of clean energy and environment in the future.
