An 80-year-old man presented with a right side lung tumor. The tumor was not abutting the bronchus or chest wall; thus, endobronchial ultrasound (EBUS) and CT-guided biopsy were considered to be technically difficult. We therefore attempted endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). Although the nodule was not abutting the esophagus on CT, an irregularly shaped hypoechoic le...

This study evaluated the basic dosimetric characteristics of a Dynamic Multi Leaf Collimator (DMLC) using a diode detector and film measurements for Intensity Modulated Radiation Therapy Quality Assurance (IMRT QA). The EGSnrc Monte Carlo (MC) simulation system was used for the determination of MLC characteristics. Radiation transmission and abutting leaf leakage relevant to the LinaTech DMLC H...

Elliptic and hyperbolic partial differential equation methods for generating both surface and volume structured grids have been implemented in the Gridgen software system. Their implementation provides the means by which very high quality quad and hex grids can be generated for computational fluid dynamics (CFD). The grids, in turn, provide the basis for highly accurate CFD simulations of visco...

A 60 year-old male patient presented with complaints of fever with chills, pain abdomen and diarrhoea for 15 days. On evaluation the patient had hepatomegaly with tenderness in right hypochondrium and epigastrium. USG abdomen revealed liver abscess involving left lobe of liver. Serology for Entabmoeba histolytica was found to be positive. CT abdomen noted that the abscess was closely abutting t...

This study examines how judgments of a region's contrast are influenced by components of a heterogeneous surround. Each stimulus comprised a 5x5 grid of squares in a homogeneous background of fixed mean luminance, with the central square the target. On a given trial, the task was to judge (with feedback) whether the (Weber) contrast of the target was 0.04 or -0.04 (relative to the background); ...

The Worldometer Coronavirus registered six million deaths on March 03, 2022. 85% of the occurred in lands directly abutting World Seas and Oceans. WHO, CDC other Public Health Organizations suggest that humidity can aid fight against COVID-19 [1]. boundary this comment is it directed at indoor air quality with perspective 40-60% positive COVID-19. fact almost all are Major Oceans, their inheren...

Epigenetic modifications play significant roles in adaptive evolution. The tumor suppressor p53, well known for controlling cell fate and maintaining genomic stability, is much less known as a master gene in environmental adaptation involving methylation modifications. The blind subterranean mole rat Spalax eherenbergi superspecies in Israel consists of four species that speciated peripatricall...
