Muscle force production with low and medium frequency burst modulated biphasic pulsed currents.

Objective: Russian current, a medium frequency burst modulated alternating current (BMAC), is widely used for NMES, but has not been shown to elicit forces near voluntary maximum. In contrast, low frequency BMAC has been shown to produce greater force production than Russian and most recently, medium frequency burst modulated biphasic pulsed current (BMBPC) elicited greater force than Russian. Whether low frequency BMBPC yields greater force than medium frequency BMBPC is unknown.

Colocalization of mineralocorticoid and EGF receptor at the plasma membrane.

The mineralocorticoid receptor (MR), a ligand-activated transcription factor expressed in various cell types (e.g. epithelial cells, neurons, smooth muscle cells, immune cells), plays important roles in neurohumoral, neuronal, cardiovascular, renal and intestinal function.

Is vaginal douching related to cervical carcinoma?

The association between cervical carcinoma and vaginal douching was examined in a population-based case-control study conducted in the low-risk population of Utah between 1984 and 1987. The authors compared 266 cases of in situ and invasive cervical carcinoma with 408 group-matched controls by vaginal douching behavior, controlled for age, lifetime number of sex partners, cigarette smoking history, religious activity, and educational level. Essentially no association was found in women who douched once per week or less, but in those who douched more than once per week, a consistent relation was demonstrated (adjusted odds ratio = 4.

Smoking behavior and attitudes of employees of a large HMO before and after a work site ban on cigarette smoking.

Smoking-related data collected during 1976-87 by anonymous cross-sectional surveys of nonphysician employees of a large medical care organization were used to assess how a work site smoking ban affected employees' smoking behavior and attitudes. The smoking ban was implemented at 11 work sites at various times during 1985-86. All work sites had three or more pre-ban surveys and one or two post-ban surveys.

Implications of pregnancy for residents and their training programs.

This study investigated the implications of pregnancy on residents and their training programs and how programs have planned for pregnancy disruptions compared to other employers. We received questionnaires from 236 male and female residents and their families who had experienced at least one pregnancy during their training. Results for female residents were compared with working spouses of male residents.
