Results: Increased levels of salivary cortisol were detected in 3 cases, all of them within the group of patients with RAS. In none of the control group patients the level of salivary cortisol was increased. The mean level of salivary cortisol was 0.64 mg / dl (range 0.2 to PP2 1.62) for patients with RAS and 0.57 mg / dl (range 0.25 to 1.09) for controls.
Conclusion: Salivary cortisol levels are not statistically higher in patients with active lesions of RAS.”
“Aim: Preterm delivery is defined as a birth before 37 weeks’
gestation and is the cause of two-thirds of perinatal mortality and thus one of the major problems in obstetrics. Its etiology is unknown, but hormonal factors have been reported to play a part. Progesterone is GSK3326595 cost a placental hormone and effective in maintaining pregnancy. The aim of this study is to evaluate the efficacy of 17 alpha-hydroxyprogesterone caproate in the prevention of preterm delivery.
Methods: This interventional study was performed with 100 pregnant women who had been referred to the Obstetrics Clinic of Ghaem Hospital (related to Mashhad University of Medical
Sciences) during 2007 to 2008. They were randomly divided into two groups of 50 cases and 50 controls. The case group received 250 mg of intramuscular 17 alpha-hydroxyprogesterone caproate weekly from 16 weeks’ gestation up to a selleck maximum of 37 weeks’ gestation. In the control group, routine perinatal care was performed and the pregnancy outcomes were compared in both groups.
Results: The mean gestational age was 36 weeks in the case group and 34 weeks in the control group. The mean birth weight was 2695 g in the case group and 2399 g in the control group. A significant difference was observed between the two groups in terms of gestational age and birth weight (P < 0.05).
Conclusion: Weekly administration of 17 alpha-hydroxyprogesterone caproate to pregnant women with a history of preterm delivery was associated with a decrease in preterm delivery and improvement
in birth weight.”
“Reverse flow-injection analysis (rFIA) involves injection of the detection reagent into a mobile phase of sample. rFIA is one of the FIA modes used to minimize reagent consumption, decrease sample dispersion, improve mixing efficiency and enhance the sensitivity. This simple, inexpensive approach is also applied to multi-component analysis by sequential injection of different reagents in the flowing stream of the sample. rFIA is particularly important in water analysis due to the abundance of the sample.
We describe several methods for determination of cations, anions, and organic substances. We also review other applications, such as pharmaceutical, biomedical and industrial analysis. (C) 2012 Elsevier Ltd. All rights reserved.
