A Quantitative Assessment of Apoptotic Index with Varying Histological Degree of Dysplasia and Squamous Cell Carcinoma of Oral Cavity - A Light Microscopic Study.

Aim And Objective: The aim of the present study was to quantitatively assess the apoptotic index at a light microscopic level in hyperkeratosis with varying histological degrees of dysplasia and different grades of oral squamous cell carcinoma (OSCC) and its correlation with prognostic significance.

Study Design: The study included the histo-pathologically diagnosed cases of hyperkeratosis with varying degrees of dysplasia and different grades of OSCC, which were retrieved from the archives of the department, and clinical details were retrieved from the case records of the patients. The sample size consisted of 80 biopsied cases, divided into seven groups of 10 experimental cases and one group of 10 cases of normal mucosa as a control group.

TeM-DTBA: time-efficient drug target binding affinity prediction using multiple modalities with Lasso feature selection.

Drug discovery, especially virtual screening and drug repositioning, can be accelerated through deeper understanding and prediction of Drug Target Interactions (DTIs). The advancement of deep learning as well as the time and financial costs associated with conventional wet-lab experiments have made computational methods for DTI prediction more popular. However, the majority of these computational methods handle the DTI problem as a binary classification task, ignoring the quantitative binding affinity that determines the drug efficacy to their target proteins.

Analysis of erythrocytes in oral submucous fibrosis - A morphometric study.

Background: Oral submucous fibrosis (OSMF) is a chronic progressive scarring oral disease caused due to areca quid chewing. The constituents of areca nut can enter into the circulation by swallowing the liquid mixture of areca quid which evokes oxidative stress on RBC membrane integrity.

Aims: To study the morphometric characteristics of erythrocytes under light microscopy and to assess the role of areca quid constituents on the morphology of circulating erythrocytes.

Thermal stress inside a disabled submarine.

Background: Submarine operations require strict adherence to standard operating and safety procedures and errors in judgement or accidents could lead to catastrophe and impair the submarine's ability to surface. In case of disablement of a submarine (DISSUB), the crew would have to survive inside the submarine for a variable period awaiting rescue. Microclimate and habitability of the submarine would have to be maintained and crew would have to consume emergency rations and water.
