Probing the Influence of Hybrid Thread Design on Biomechanical Response of Dental Implants: Finite Element Study and Experimental Validation.

This study aimed to perform quantitative biomechanical analysis for probing the effect of varying thread shapes in an implant for improved primary stability in prosthodontics surgery. Dental implants were designed with square (SQR), buttress (BUT), and triangular (TRI) thread shapes or their combinations. Cone-beam computed tomography images of mandible molar zones in human subjects belonging to three age groups were used for virtual implantation of the designed implants, to quantify patient-specific peri-implant bone microstrain, using finite element analyses.

Intravenous dexmedetomidine versus propofol for intraoperative moderate sedation during spinal anesthesia: A comparative study.

Background And Aims: There has been a paradigm shift of focus toward quality of spinal anesthesia with sedation being an integral aspect of this regional anesthesia technique. Thus, this study was designed to compare efficacy of intravenous dexmedetomidine and propofol for moderate sedation during spinal anesthesia.

Material And Methods: A total of 120 patients of age group 18-60 years of American Society of Anesthesiologists grade I & II, posted for surgeries under spinal anesthesia were randomly divided in to three groups (n = 40 each); Group D received infusion of dexmedetomidine 1 μg/kg over 10 min followed by maintenance infusion of 0.

Effect of intravenous clonidine premedication for the bloodless surgical field in patients undergoing middle ear or nasal surgery: A comparison of three different doses.

Aim: To evaluate the effect of intravenous (IV) clonidine premedication for the bloodless surgical field in patients undergoing middle ear or nasal surgery comparing three different doses.

Subjects And Methods: This prospective randomized, clinical trial was performed on 90 normotensive patients belonging to American Society of Anesthesiologists grade I/II, aged 18-60 years, of either sex, undergoing routine middle ear or nasal surgery. These patients were divided into three Groups A, B, and C with 30 patients in each according to the dose of IV clonidine used as premedicant that is 3, 4, and 5 µg/kg, respectively.

Study of thrombocytopenia in patients of malaria.

Background: Malaria is a Protozoal disease caused by infection with parasites of the genus Plasmodium and transmitted to man by certain species of infected female Anopheline mosquito. In 2008 there were 1.52 million cases of malaria in India, out of which 0.

Antifilarial activity of ethyl acetate extract of Vitex negundo leaves in vitro.

Objective: To evaluate the possible antifilarial effect of ethyl acetate extract of Vitex negundo (Verbenaceae) leaves against Setaria cervi filarial parasite in vitro.

Methods: In vitro screening was done by the method of motility inhibition and MTT reduction assay with concentrations of 0.03 to 1.
