Technical note: Radiofrequency ablation of hepatocellular carcinoma with contrast-enhanced ultrasound guidance: First Indian experience

Radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) is an established alternative treatment to surgery and intra-arterial chemotherapy, usually performed under contrast-enhanced CT scan guidance. We describe our experience with the use of contrast-enhanced ultrasound and contrast dynamics analysis for planning and monitoring RFA in a patient with HCC

Buckling Analysis of Roll Cage Using Finite Element Analysis

Abstract — The present paper is based on frame buckling analysis of ATV roll cage through finite element procedures.This analysis was performed using CATIA software. The detailed three dimensional model geometry of roll cage is worked out. The meshing of the part blower is done and the details of the finite element mesh are calculated. The roll cage is subjected to the load environment. The actual load conditions are worked out and the boundary conditions are given.This analysis comprises of material selection, structure computation, restraint computation, load computation, stiffness computation, singularity computation, constraint computation, factorized computation, direct method computation, geometric stiffness computation and buckling computation and at last global sensors

Endovenous Ablation of Saphenofemoral Insufficiency: Analysis of 100 Patients Using RF Closure Fast Technique

Chronic venous insufficiency is a common problem leading to varicose veins of lower limbs which was traditionally being treated with ligation and stripping. Endovenous ablation is an attractive alternative minimally invasive technique to treat such patients. We analysed the results of 100 consecutive patients treated with Radiofrequency based endovenous ablation using Closure Fast Catheter. Retrospective analysis of 100 consecutive patients with chronic venous insufficiency treated at our institution was done. All patients were classified pre and post procedure based on clinical, etiologic, anatomic and pathophyslogical classification, Venous clinical severity and Venous disablitity scores alongwith color doppler examination with follow up done at 2 weeks, 3 months and one year for any disease recurrence or residual symptoms. 97 of the 100 patients treated at 3 months and at 1 year showed good reduction of venous clinical severity and Venous disability scores to 0. Doppler showed complete closure of saphenofemoral junction and long saphenous vein at 2 weeks with no recanalisation at one year. No thrombus formation was observed. Minor complications like ecchymosis was seen in 9 patients and thrombophlebitis in 4 patients. Endovenous ablation using radiofrequency with Closure Fast technique showed improved short and long term results in patients with venous insufficiency with 100% closure seen on doppler studies along with lesser complications and no thrombus formation due shortened procedure time and improved catheter design

Comparative study of son preference in India and China : assessing policy interventions to address discrimination against girls; final technical report

India and China have similar patterns of gender discrimination, similar patriarchal kinship systems, and are experimenting with relatively similar policy approaches. The project conducted a comparative analysis of policies that address discrimination against girls, mapping all policy interventions that seek to address daughter discrimination in each country, and reviewing literature on son preference. Discriminatory practices affect girls’ ability to live a life free of violence and coercion, and to realize rights and freedoms starting from birth. These factors also affect broader demographic structures and social, cultural, and political life of both India and China. Project outputs are detailed in the report
