OBJECTIVES This study evaluated the microleakage at the implant/abutment interface of external hexagon (eH) implants and abutments with different amounts of bacteria and tightening torques. MATERIAL AND METHODS A bacterial suspension was prepared to inoculate the implants. The first phase of this study used nine EH implants and abutments that were divided into three groups with different amou...

results the results obtained for each drug were compared with other drugs and also with the results of the control groups. the results related to promastigote and amastigote assays showed that when the dose of both drugs increased, the parasite number is reduced in comparison with the control groups. moreover, the parasitic burden in the test cultures decreased significantly. macrophage assay r...

objective: to evaluate the efficacy of in vitro sperm activation (isa) using non-liquefied versus liquefied asthenozoospermic semen samples for improvement of sperm parameters. materials and methods: fifty six oligoasthenozoospermic (oa) patients (age range: 22-44 years; mean: 32.089 years) were enrolled in this study. oa patients were classified according to type of infertility. also, duration...

traumatic brain injury (tbi) is caused by rapid deformation of the brain, resulting in a cascade of pathological events and ultimately neurodegeneration. in vitro models of tbi can help us to describe the pathobiological mechanisms. in vitro models of brain injury support a platform for performing repeatable, well-controlled, environmentally isolated experiments. other advantages of in vitro mo...

Interleukin 2 (11-2) coupled to polystyrene beads to form a solid phase of the cytokine was able to increase the cytotoxic activity of rat spleen cells in vitro. A single injection of the IL-2 coupled beads into the peritoneal cavities of normal rats also resulted in the in vivo activation of cytotoxicity of peritoneal exÃodatecells, whereas a single i.p. injection of the same amount of soluble...

OBJECTIVES To assess the caries risk and contribution of diet, bacteria, circumstances and susceptibility sectors among special groups in comparison to the normal group of Udaipur using the Cariogram model. MATERIALS AND METHODS A Cariogram model was used to identify risk factors among 160 subjects (40 mentally challenged, 60 visually impaired and 60 normal healthy individuals) aged 7-36 year...
