We examined the effect of the orientation of a figure-of-eight coil on the latency of surface electromyographic (EMG) responses and the firing pattern of single motor units evoked in the first dorsal interosseous muscle by transcranial magnetic brain stimulation. Two coil positions were used: the coil held on a parasagittal line either with the induced(More)
INTRODUCTION This study set out to compare the efficacy of laser-activated and ultrasonically activated root canal disinfection with conventional irrigation, specifically its ability to remove bacterial film formed on root canal walls. METHODS Seventy human premolars were shaped to an apical size #20, taper .07, sterilized, and contaminated in situ with(More)
Basic fibroblast growth factor (FGF-2) may protect the heart from ischemia-reperfusion injury (stunning) by stimulating nitric oxide (NO) production. To test this hypothesis, we pretreated coronary-perfused mouse hearts with 1 microg/ml FGF-2 or vehicle control before the onset of ischemia. Intracellular calcium (Ca(i)(2+)) was estimated by aequorin, and NO(More)
To characterize and quantitate pathways of stimulation of gastric secretion via vagal excitation induced by 2-deoxy-D-glucose, we used graded doses of the two muscarinic antagonists, atropine and pirenzepine. Studies were performed in four conscious gastric fistula dogs with antral vagotomy to eliminate the gastrin release component of the vagal response.(More)
BACKGROUND Potential pain with IUD insertion is a concern for women. Studies have found that systemic and local cervical therapies do not reduce pain scores. Since intrauterine infusion of lidocaine may reduce pain with endometrial aspiration, in this pilot study, we tested whether such infusion through an inexpensive endometrial aspirator could reduce IUD(More)
Neurons receive input from the outside world or from other neurons through neuronal receptive endings (NREs). Glia envelop NREs to create specialized microenvironments; however, glial functions at these sites are poorly understood. Here, we report a molecular mechanism by which glia control NRE shape and associated animal behavior. The C. elegans AMsh glial(More)
Adipose tissue is an important metabolic organ that integrates a wide array of homeostatic processes and is crucial for whole-body insulin sensitivity and energy metabolism. Brown adipose tissue (BAT) is a key thermogenic tissue with a well-established role in energy expenditure. BAT dissipates energy and protects against both hypothermia and obesity. Thus,(More)
