Background Reduced ovarian reserve has been known to predict poor ovarian response and poor success rates in infertile women undergoing assisted reproductive technology. Ovarian reserve also decreases with age but the rate of decline defers from a woman to another. The aim of this study was to detect any difference in ovarian reserve as measured by basal serum FSH and AMH between matched cohort...

We consider the model with discrete innovations introduced in [1] and studied in [2–9]. In this model the state of the economy is determined by a set of operating technologies, a collection of funds corresponding to these technologies, and a set of known, but as yet not implemented technologies. To introduce a new technology, expenditures of the already utilized types of funds are required. As ...

BACKGROUND Polycystic ovarian disease is one of the most common causes of infertility in women of reproductive age. Anti- mullerian hormone (AMH), a member of transforming growth factor (TGF) family which is secreted by granulosa cells of growing follicle, is found to be increased to three to four fold in Poly Cystic Ovarian Syndrome (PCOS) patients as evidenced by previous studies. But the lev...

Recent interest in using marine reserves for marine resource management and conservation has largely been driven by the hope that reserves might counteract declines in fish populations and protect the biodiversity of the seas. However, the creation of reserves has led to dissension from some interested groups, such as fishermen, who fear that reserves will do more harm than good. These perceive...

Recent progress suggests that integrative cardiac reserve is important in coronary artery disease, chronic heart failure, cardiomyopathy, and other cardiovascular diseases. Integrative cardiac reserve includes coronary flow reserve, myocardial reserve, energy reserve, and heart rate reserve. In the case of stress reaction, coronary flow reserve can provide excessive blood and energy supply and ...

AIMS Dobutamine stress echocardiography (DSE) is widely used to evaluate myocardial contractile reserve in patients with heart failure (HF). The aim of the study was to assess the relationship between the tissue Doppler (TD) mitral annulus systolic velocity (Sm) change during DSE, contractile reserve, and aerobic exercise capacity in HF patients. METHODS AND RESULTS Sixty-four HF patients (ag...

OBJECTIVE To assess resting and exercise echocardiography for prediction of left ventricular dysfunction in patients with significant asymptomatic aortic regurgitation. DESIGN Cohort study of patients with aortic regurgitation. SETTING Tertiary referral centre specialising in valvar surgery. PATIENTS 61 patients (38 men, 23 women; mean (SD) age 53 (14) years) with asymptomatic or minimall...

The aim of this study was to clarify the predictive value of fractional flow reserve (FFR) determined by myocardial perfusion imaging (MPI) using thallium (Tl)-201 IQ-SPECT without and with computed tomography-based attenuation correction (CT-AC) for patients with stable coronary artery disease (CAD). We assessed 212 angiographically identified diseased vessels using adenosine-stress Tl-201 MPI...

results higher levels of stress were due to the fear of being infected by hiv and hepatitis patients with mean of 3.2 and 58%; and lack of weekends with mean of 3 and 44%. the lowest levels of stress were related to inadequate skills with mean of 2.18 and 32%, and environment light with mean of 2.14 and 34.7%. stress was significantly related to job status, conflict of doctors and nurses as wel...
