Evaluation of the Efficacy of LASER, Desensitizing Agents, and their Combined Effect on Dentinal Hypersensitivity in Bicuspids: Study.

Aim: This study aimed to know the potential of diode light amplification by stimulated emission of radiation (LASER) and desensitizing agents on blocking the dentinal tubules, which may further help in reducing the most common dental problem named dentinal hypersensitivity (DH).

Materials And Methods: Sixty human permanent bicuspids were selected, and preparation was performed in the cervical region measuring 2.5 mm × 2.

To Evaluate the Antimicrobial Activity of PRP and PRF with and without Nanosilver.

Aim: To evaluate the antimicrobial activity of PRP and PRF with and without nanosilver.

Materials And Methods: The materials were tested in powdered form is nanosilver. The nanosilver particles was mixed to form with PRP and PRF so as to placed in a wells followed the groups are experimental groups; Group I: PRP + nanosilver particles, Group II: PRF + nanosilver and control group: PRP and PRF and normal saline.

Sweet Potato Peels and Cancer Prevention.

A bioassay-guided fractionation of an alcoholic extract from the peels of Ipomoea batatas Lam has been carried out. Sulforhodamine B and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays were used to evaluate the anticancer and antioxidant potential, respectively, while silica gel column chromatography (CC) was used to isolate compounds that were characterized using 1D- and 2D-NMR (Nuclear Magnetic Resonance) and mass spectrometry. The alcoholic extract was fractionated into n-hexane, ethyl acetate, n-butanol, and water.

Natural antifungal compounds from the peels of Ipomoea batatas Lam.

Three antifungal compounds have been isolated for the first time from the peels of Ipomoea batatas Lam. Their structures were established on the basis of 1D and 2D NMR spectra data as well as ESI-MS and IR analysis. Urs-13(18)-ene-3β-yl acetate was found to possess a weak activity against Sporothrix schenckii and Trichophyton metagrophytes fungi with an MIC value of 50 μg/mL each.

Anti-secretory and cyto-protective effects of chebulinic acid isolated from the fruits of Terminalia chebula on gastric ulcers.

In continuation of our drug discovery program on Indian medicinal plants, the gastro protective mechanism of chebulinic acid isolated from Terminalia chebula fruit was investigated. Chebulinic acid was evaluated against cold restraint (CRU), aspirin (AS), alcohol (AL) and pyloric ligation (PL) induced gastric ulcer models in rats. Potential anti-ulcer activity of chebulinic acid was observed against CRU (62.

Inhibition of hyaluronidase activity of human and rat spermatozoa in vitro and antispermatogenic activity in rats in vivo by Terminalia chebula, a flavonoid rich plant.

Our interest in development of hyaluronidase inhibitors as male antifertility agents led to identification of Terminalia chebula (T. chebula) plant with hyaluronidase (HAase) inhibitory activity of human spermatozoa ( approximately 93% inhibition) and rat caudal epididymal spermatozoa ( approximately 86% inhibition) in vitro at 30 mg/ml. We further demonstrated inhibition of hyaluronidase activity of testis and epididymal spermatozoa in vivo coincident with antispermatogenic activity and contraceptive efficacy of TC extract administered at 50 and 100mg/kg/day orally for 60 days in male albino rats.
