The purpose of this study was to examine the effect of oral contraceptive (OC) use on salivary secretory immunoglobulin A (SIgA) levels at rest and in response to an acute bout of moderate-vigorous exercise during 2 phases of the 4-week OC cycle corresponding to different phases of the synthetic menstrual cycle. Ten healthy active females completed a cycling at 70% peak oxygen uptake for 45 min...
Objectives: To assess the cost-effectiveness of computed tomography colonography (CTC) for a colorectal cancer screening program in a working population (aged 40–60 years) from a health care payer’s perspective in Japan. Methods: A Markov model for colorectal cancer was constructed to estimate the long-term (10-year, 20-year, and 30year) effect of introducing CTC for three different strategies ...
In this study, we examined whether weight loss-induced changes in plasma organochlorine compounds (OC) were associated with those in skeletal muscle markers of glycolytic and oxidative metabolism. Vastus lateralis skeletal muscle enzyme activities and plasma OC (Aroclor 1260, polychlorinated biphenyl 153, p,p'-DDE, beta-hexachlorocyclohexane, and hexachlorobenzene) were measured before and afte...
Ovarian cancer (OC) is the fifth cancer death cause in women worldwide. The malignant nature of this disease stems from its unique dissemination pattern. Epithelial-to-mesenchymal transition (EMT) has been reported in OC and downregulation of Epithelial cadherin (E-cadherin) is a hallmark of this process. However, findings on the relationship between E-cadherin levels and OC progression, dissem...
BACKGROUND Recently low dose organochlorine (OC) pesticides have been strongly linked to various chronic diseases including diabetes and cardiovascular diseases. Both field and animal studies have suggested a possibility that persistent lipophilic chemicals like OC pesticides can cause vitamin D deficiency, but there have been no human studies of exposure to any chemical as a possible cause of ...
Changes in the maternal environment can induce fetal adaptations that result in the progression of chronic diseases in the offspring. The objective of the present study was to evaluate the effects of maternal chronic sleep restriction on blood pressure, renal function and cardiac baroreflex response on male offspring at adult age. Female 3-month-old Wistar rats were divided in two experimental ...
Oseltamivir is a potent inhibitor of influenza virus neuraminidase enzymes essential for viral replication. This study aimed to investigate the impact of covariates on pharmacokinetic (PK) variability of oseltamivir and its active metabolite form, oseltamivir carboxylate (OC). Dosing history, plasma drug concentrations, and demographic information were pooled from 13 clinical trials providing d...
در این پایان نامه، نانوپودرهای سرامیکی pb(zr1-xtix)o3 به ازای x=0/05 به روش احتراق ژل تهیه شدند. خواص ساختاری و اپتیکی آنها در دماهای کلسینه مختلف (oc500، oc600، oc700 و oc800)مورد بررسی قرار گرفتند. پارامترهای اپتیکی از جمله ضریب شکست، قسمت حقیقی و موهومی تابع دی الکتریک و فونون های اپتیکی، در گستره عدد موج 400-4000cm-1، به کمک روابط کرامرز- کرونیگ محاسبه شده اند. بررسی ها نشان دادند که در دما...
Cement manufacture has undergone extensive change in its attempts to rise to the successive challenges posed by society. The hydration of Portland cement is a complex phenomenon that depends on both reagent characteristics and reaction conditions. It is a well-known fact that the curing temperature plays an important role on the hydration kinetics. The present study is the first to be undertake...
Background and Purpose—Controversy persists as to whether oral contraceptive (OC) use and reproductive history play a role in the etiology of stroke, particularly ischemic stroke. Our aim was to investigate this question in a cohort of middle-aged Swedish women. Methods—The Women’s Lifestyle and Health Cohort Study included 49 259 Swedish women, aged 30 to 49 years at baseline (1991 to 1992). P...
