Studies of myocardial aging are complex and the mechanisms involved in the deterioration of ventricular performance and decreased functional reserve of the old heart remain to be properly defined. We have studied a colony of beagle dogs from 3 to 14 yr of age kept under a highly regulated environment to define the effects of aging on the myocardium. Ventricular, myocardial, and myocyte function...
Intermittent nature of wind power faced ISO and power producers with new challenges. Wind power uncertainty has increased the required reserve capacity and deployment reserve. Consequently, large-scale wind power generation increases ISO costs and consequently reserve prices. On the other hand, since wind power producers are price taker, large-scale wind power generation decreases residual dema...
pancreas, is a serious condition that manifests in either acute, chronic or acute on chronic forms leading to abdominal pain. Acute pancreatitis has a sudden onset and short duration, whereas chronic pancreatitis develops gradually and worsens over time, resulting in permanent organ damage. It may result in progressive destruction of the exocrine tissue and in some patients a loss of endocrine ...
forest reserves are one of the most important approaches in ecosystem management in iran. in order to determine the effects of reserve management on plants diversity (woody plants and ground flora) in three zones (core zone, buffer zone, and transmission zone of chamhesar pear forest reserve), we mapped land form units. then 18 main sampling units (20×50=1000 m2) distributed randomly were chose...
With the population aging, cancer in older persons is becoming an increasingly common problem.[1] The benefit of antineoplastic treatment may be diminished and the risk enhanced by aging, due to a progressive reduction in life expectancy and in the functional reserve of multiple organ systems.[ 2] To establish the most suitable course of action in individual cases, the practitioner needs to be ...
The human ovary is a dynamic organ which continually changes in size and activity through life, as an integral part of the changes that the female is going through before during and after her reproductive life. Following the rapid increase in the use of transvaginal scan in recent years, the measurement of ovarian volume has become quick, accurate and cost-effective. Ovarian volume is an import...
Anemia is a wide spread condition world-wide associated with increased loss of quality of life, organ failure and mortality. Its causes are multifactorial including iron deficiency, heart and renal failure, COPD, malignancies, various infectious and inflammatory diseases, and blood loss such as occurs in trauma and GI bleeding. The underlying reason why anemia is considered to be life threateni...
This paper introduces the concept of personalized physiological medicine that is specifically directed at the needs of the critically ill patient. This differs from the conventional view of personalized medicine, characterized by biomarkers and gene profiling, instead focusing on time-variant changes in the pathophysiology and regulation of various organ systems and their cellular and subcellul...
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 cohor...
Expectation has an important role in oil price fluctuation and it seems which one of the important factors is for changing supply behaviour however oil price changes. Identification of mentioned expectation could help us for partly and continuously control the oil market situation.one of the important factor that could have effects on future oil price expectation is volume of current reserve oi...
