The aim of the present study was to determine the levels of cadmium in the muscle, liver and kidney of cattle from Isfahan and to compare the results with those reported by other countries and with the maximum acceptable levels for human consumption. Samples of muscle, liver and kidney from 60 animals aged 1–10- year-old were collected from the carcasses slaughtered at Isfahan abattoir. Samples...

c-Myc is frequently overexpressed in tumors and plays an important role in the regulation of cancer metabolism. Hypoxia-inducible factor-1 (HIF1), the master regulator of the hypoxic response, enhances tumorigenesis and influences metabolism via upregulation of the glycolytic pathway and suppression of mitochondrial respiration. Together, deregulated Myc and HIF1 cooperate to lend metabolic adv...

Studies of the cardiac output of normal individuals during muscular exercise have been made by several investigators (l-5). Systemic blood pressure has likewise been measured during exercise, making possible the calculation of peripheral resistance and the work of the left ventricle. Until recently (5), such information was not available in the case of the right ventricle because pulmonary arte...

The net effects of switching from consumption taxation to inflation taxation on resource allocation and welfare crucially depend on production externalities. With elastic labor supply, raising inflation taxation decreases leisure, but increases the levels of real consumption, capital, and output. Moreover, this tax switch has two opposing effects on the level of real money balances: A positive ...

Both electrically induced exercise and infusion of 2,4-dinitrophenol (DNP) increased oxygen consumption and tissue metabolism in chloralose-anesthetized dogs. Cardiac output increased with oxygen consumption at the same rate in both experimental conditions. The increase in cardiac output induced by exercise was, as expected, accompanied by increases in both lactate-to-pyruvate ratio and "excess...

The objective of this study was the estimation of the exposure over time to heavy metals (cadmium, mercury, and lead) due to shellfish consumption in the Veneto Region, Italy. Shellfish consumption was investigated by a food frequency consumption survey. Altogether, 1949 households, stratified into the five most populated areas of the Veneto Region, were involved in the study. Exposure estimati...

Cadmium, a toxic heavy metal, is widely present in food. It has been reported that chronic cadmium exposure is associated with kidney disease, osteoporosis, cardiovascular disease and cancer. The aim of this study was to assess the dietary cadmium exposure and potential health risk in different age-sex groups of the Chinese population (children aged 4-11 years, young people aged 12-17 years and...

BACKGROUND AND OBJECTIVES Few studies have invasively assessed diastolic functional reserve and serial changes in left ventricular hemodynamics in euvolemic patients with exertional dyspnea. In this study, sequential changes in left ventricular end-diastolic pressure (LVEDP) to leg-raise exercise were measured invasively in patients with early heart failure with preserved ejection fraction (HFp...
