the use of corticosteroids is one of the methods put forward for the strengthening and speeding up the process of labor. after identification of glucocorticoid receptors in human amnion, the role of corticosteroids in starting the process of labor has been studied in numerous studies.the purpose of this study was to determine the effect of intravenous dexamethasone on preparing the cervix and o...

skilled labor force is very important in economic growth. workers become skilled when they are healthy and able to be educated and work. in this study, we estimated the effects of health indicators on labor supply. we used labor force participation rate as the indicator of labor supply. we categorized this indicator into 2 indicators of female and male labor force participation rates and compar...

Physiology in microgravity is a challenging field of research because of limited resources. Though humans have been in space for 50 years most meaningful data has been collected only within the last 15 years. While expensive studies with small sample sizes make obtaining and interpreting data difficult, some general conclusions about the human physiological response to microgravity can be drawn...

Owing to multiplanar imaging capabilities and excellent tissue characterization, MRI can facilitate definitive diagnosis of benign conditions of the female pelvis. The purpose of this chapter is to review the spectrum of common benign conditions of the female pelvis and to illustrate the MRI features of these conditions, with an emphasis on the key imaging characteristics to suggest accurate di...

Anatomic and Physiologic Considerations Nerve fibers subserving the sense of smell have their cells of origin in the mucous membrane of the upper and posterior parts of the nasal cavity (superior turbinates and nasal septum). The entire olfactory mucosa covers an area of about 2.5 cm2 and contains three cell types—the olfactory or receptor cells (which number between 6 and 10 mil l ion in each ...

MUCH has been written relative to the physiologic abnormalities produced by mitral stenosis and insufficiency. Most of the data and the concepts derived therefrom have been obtained by right heart catheterization.'--8 The introduction of left heart and combined heart catheterization9-19 has greatly enhanced the value of physiologic study in patients with rheumatic mitral valve disease and has p...

results there were significant differences between the groups in subjective labor pain scores (except vas 4) (p < 0.001). the duration of the phase one (3 cm dilatation to full dilatation) and phase two (full dilatation to birth) in the acupressure group was shorter than the control group (phase one, 225 min and 320 min, respectively; phase two, 15 min and 20 min, respectively; both p < 0.001)....
