Levenberg-Marquardt deep neural watermarking for 3D mesh using nearest centroid salient point learning.

Watermarking is one of the crucial techniques in the domain of information security, preventing the exploitation of 3D Mesh models in the era of Internet. In 3D Mesh watermark embedding, moderately perturbing the vertices is commonly required to retain them in certain pre-arranged relationship with their neighboring vertices. This paper proposes a novel watermarking authentication method, called Nearest Centroid Discrete Gaussian and Levenberg-Marquardt (NCDG-LV), for distortion detection and recovery using salient point detection.

Herbal Combination 'HAGE-101912' Ameliorates Gastroesophageal Reflux Disease in Rats.

Background: Gastroesophageal reflux disease (GERD) is a chronic, relapsing disorder. In this era of modern and fast-track lifestyle and food habits, the incidence of GERD is rapidly increasing. Currently, proton pump inhibitors (PPIs) are the primary choice of treatment.

Bidis--hand-rolled, Indian cigarettes: induced biochemical changes in plasma and red cell membranes of human male volunteers.

Objective: To investigate the effect of bidi smoking on erythrocyte antioxidant status, membrane fluidity.

Design And Methods: Thirty experimental and control subjects (mean age 35+/-5) were selected for the study. Experimental subjects smoke 22+/-4 bidis per day for 8-10 years.

Chronic exposure to pyrethroid-based allethrin and prallethrin mosquito repellents alters plasma biochemical profile.

Continuous exposure of humans to pyrethroid-based mosquito repellents for longer durations may lead to adverse health effects. No information is available on long-term use of these mosquito repellents pertaining to the biochemical changes in human subjects. Therefore, the present study is an attempt to evaluate the status of health in human volunteers exposed to two commercially available mosquito repellent pyrethroids, allethrin and prallethrin, in terms of changes in plasma biochemical profile.

Prallethrin induced biochemical changes in erythrocyte membrane and red cell osmotic haemolysis in human volunteers.

Changes in biochemical composition in erythrocyte membrane, erythrocytic osmotic haemolysis, and nitrite and nitrate levels in plasma were analyzed in 12 human volunteers who were exposed regularly to prallethrin, a type I pyrethroid mosquito repellent. The results revealed a decrease in cholesterol (C) and phospholipid (P) moieties in erythrocyte membrane with no consequent change in C:P ratio. Further, a significant decrease in the content of phosphatidyl serine suggested that PS is a sensitive phospholipid species to the pyrethroid action.
