Engineered nanoparticles are developed for various applications in industrial, electrical, agricultural, pharmaceutical and medical fields due to their unique properties. Nanoparticles such as TiO(2) and ZnO are widely used in cosmetics for UV protection. The toxicological investigations of ZnO NPs are highly recommended because of the increasing use in(More)
The aim of the study was to evaluate the cells-nanoparticle interactions and molecular toxicity after delayed hypersensitivity in Guinea pigs, exposed to hydroxyapatite nanoparticles (HANP). The study focuses on synthesizing and characterizing HANPs and gaining an insight into the cytotoxicity, molecular toxicity, hypersensitivity and oxidative stress(More)
Obesity is associated with insulin resistance and abnormal peripheral tissue glucose uptake. However, the mechanisms that interfere with insulin signaling and glucose uptake in human skeletal muscle during obesity are not fully characterized. Using microarray, we have identified that the expression of Pid1 gene, which encodes for a protein that contains a(More)
The toxicological evaluation of the plant Calycopteris floribunda Lam. was done in calf, rabbit and rat. The phytochemical screening revealed the presence of flavonoids, alkaloids, tannins and saponins. Morbidity and mortality was observed in methanol extract-treated rats and rabbits. In rabbits (25 g/kg/day) and calves (35 g/kg/day) fed fresh leaves showed(More)
Shape is an important visual feature and it is one of the basic features used to describe image content. However, shape representation and classification is a difficult task. This paper presents a new boundary based shape representation and classification algorithm based on mathematical morphology. It consists of two steps. Firstly, an input shape is(More)
AIM To evaluate the efficacy of Polylactic Acid/Polygycolic Acid (PLA/PGA -Fisiograft®) with Open Flap Debridement (OFD) and OFD alone in the treatment of intrabony defects over a period of 9 months. MATERIAL AND METHODS Twenty Nine systemically healthy subjects with total of 30 defects were included in the present, randomized, controlled and two arm(More)
A series of oxazole and pyrazole derivatives of pongamol (1) were designed and synthesized to examine their anti-cancer activity. The cytotoxicity of these compounds was examined in three different human tumor cell lines, IMR-32, HeLa and Jurkat. Although all compounds tested were quite effective than the pongamol against all the three different types of(More)
