objective(s): the effect of prolonged overtraining on cytokine kinetics was compared with moderate exercise in the present study.   materials and methods: male wistar rats were randomly divided into control sedentary (c), moderate trained (mt), (v=20 m/min, 30 min/day for 6 days a week, 8 weeks), overtrained (ot) (v=25 m/min, 60min/day for 6 days a week, 11 weeks) and recovered overtrained (or)...

We have shown previously that an intravenous injection of oxytocin (OT) in ovariectomized (OVX) rats initiates a circadian rhythm of prolactin (PRL) secretion similar to that observed after cervical stimulation (CS). In this study, we investigated the pathway through which OT triggers the PRL rhythm. We first tested whether an intracerebroventricular injection of OT could trigger the PRL secret...

BACKGROUND & OBJECTIVES Oxytocin (OT) injections to milch cattle for milk letdown have become a common practice amongst dairy farmers in India. Although there is no reported evidence, it is widely presumed that long term consumption of such milk leads to adverse health consequences. However, there is no information on the effect of exogenous OT injections on milk OT content and its stability du...

Extensive industrial use of arylamines started in the middle of the 19th century in the dye industry. Because of the high incidence of bladder cancer, arylamines belong to the first and most intensively studied occupational and environmental carcinogens. In workers, biomonitoring of exposure to arylamines including ortho-toluidine started in the first half of the 20th century. This review highl...

Studies were carried out on the photodynamic inactivation of Bacillus subtilis cells by He-Ne laser irradiation in presence of methylene blue and toluidine blue. Electron paramagnetic resonance (EPR) measurements show decrease in the cell membrane nuidity due to photodynamic damage of the lipophilic compartments. Study of cell damage in presence of sodium azide, 0 20 and glutathione as well as ...

Background:-Mitotic figures refer to the various phases of mitosis which are well appreciated in tissue sections.They act as prognostic indicators in oral epithelial dysplasia. Aim:-To compare and evaluate the mitotic figures in oral epithelial dysplasia using H & E and Toluidine blue stains. Objective:-Using H&E, Toluidine blue stains in the identification and counting of mitotic figures in di...

Early detection of oral premalignant lesions (OPMLs) by visual inspection with toluidine blue has not been addressed. We conducted a community-based randomized controlled trial to assess whether using toluidine blue as an adjunctive tool for visual screening had a higher detection rate of OPMLs and could further reduce the incidence of oral cancer. In 2000, in Keelung, we randomly assigned a to...

Skill learning and instrumental conditioning have a long association with the behaviorist research program and are often thought of in terms of rote learning of simple stimulus–response (S–R) associations based on external rewards. These forms of learning have also been strongly associated with the striatum of the basal ganglia, with different striatal regions apparently making various differen...

Since the early 1990s, Optimality Theory (OT) has quickly gained ground in phonology. Its main appeal lies in two characteristics: the focus on wellformedness of the output and the softness of constraints, where a constraint can be violated in order to satisfy more important requirements. A conspicuous characteristic of classic OT is that all constraints on the output should compete with each o...
