introduction: this study compared apical dye penetration using lateral condensation technique (lc) and lc technique with a reciprocal handpiece (mechanical lateral condensation or mlc) as a new method. materials and methods: forty-eight human extracted straight canine teeth were used. after crown amputation, the teeth were randomly divided into four experimental groups of 10 teeth each and two ...

abstractl-carnitine (lc) is an antioxidant with the ability to promote the growth in vitro embryo.objective: the goal was to evaluate the effect of lc on some indicators of embryo development and blastocyst quality including zona pellucid (zp) thickness, the hatching of blastocysts and their cell numbers.materials and methods: mouse embryos were randomly divided into five groups and incubated w...

Behavioral and electrophysiological evidences have shown that locus ceruleus (LC) is involved in different tasks including modulation of sensory processing and shift of attention. In the present study, single unit responses of barrel cortical cells was recorded following controlled mechanical displacement of the principal and peripheral vibrissae in adult rats (100 trials of 200 µm deflection f...

Objective(s): The aim of the present research is to investigate the efficacy of L-carnitine (LC) as a complementary therapy to diclofenac sodium (Dic) treatment in a mono-iodoacetate (MIA) induced knee osteoarthritis (OA) rat model, with respect to pain relief and the underlying pathology.Materials and Methods: Fifty adult male albino ra...

Introduction: Inflammatory pain is a common sign of chronic diseases. Some brain regions such as locus coeruleus (LC) of the brainstem nor-epinephrine (NE) system have a key role in The mechanisms of the pain modulation and dependence. Bupropion synthesized as an antidepressant, but it is using for smoke cessation. It can change morphine withdrawal signs such as pain related behaviors. This stu...

background and objectives: food contamination by aflatoxins is an important food safety concern for agricultural products. in order to identify and develop novel antifungal agents, several plant extracts and isolated compounds have been evaluated for their bioactivities. anti-infectious activity of piper betle used in traditional medicine of malaysia has been reported previously. materials and ...

background: the glycoconjugate content of sperms indicates their physiological and fertility properties. lectin reactivity is indicative of intact, capacitated, and acrosome-reacted sperms. in the epididymis, sperms experience maturation, glycoconjugate modification, and simultaneously, higher l-carnitine (lc) concentrations. the aim of this project was to evaluate the effects of lc and pentoxi...
