Abstract

Type 2 diabetes mellitus (T2DM) and obesity have become common accompaniments with resultant increase in morbidity and mortality. Obesity by its causation of insulin resistance leads to increased risk of T2DM. Dietary modification and lifestyle changes fail to maintain weight loss and glycaemic control in the longer term. Bariatric surgery by virtue of substantial and sustained reduction of weight is increasingly proving to be an effective therapy to deal with the rising trend of complications arising out of these dual disorders. Bariatric surgeries result in higher rates of short and long-term diabetes remission. Improvement in insulin action, betacell function and hormonal interplay in the entero-insular axis seem to play major role. Our current article will provide an overview of effectiveness of bariatric surgeries and the proposed mechanisms.

Abstract

Aqueous suspension of nano zirconia with methanol was irradiated with gamma (γ ) rays. Hydrogen (H₂) generated in this process was studied as a function of pH and γ-dose. In the presence of 1 M methanol and at pH 3.0, low gamma dose irradiation showed optimum H₂ generation. This is explained on the basis zeta potential and surface charge on zirconia particles. Positive surface charge at low pH could be the reason for enhanced H₂ generation. Maximum H₂ yield G(H₂) of 3.7 was observed. This is 400 times more compared to nano pure water. The method can be utilized for building a medium-scale H₂ generation plant.
