the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
E RYTHROPOIETIN is believed to be the prime physiologic regulator of erythropoiesis.1 It is generally assumed that erythropoietin production is chiefly controlled by the demands of tissues for oxygen relative to their oxygen supply.1 According to this hypothesis transfusion-induced polycythemia results in suppression of erythropoietin production ( and consequently of erythropoiesis ) by virtue ...

In 1929 Mendel (1) discovered that nL-glyceraldehyde in concentrations of 1O-3 M almost completely inhibited the anaerobic formation of lactic acid from glucose by rat sarcoma. Glyceraldehyde, even in much higher concentrations, did not appreciably affect the respiration of normal liver, kidney, and brain, or of malignant cells. Somewhat later Mendel, Bauch, and Strelitz (2) found that the addi...
The macula densa detects changes in NaCl concentration in tubular fluid and transmits a feedback signal, known as tubuloglomerular feedback (TGF), which helps to control glomerular afferent arteriole resistance. We and other investigators have reported that synthesis of NO in the macula densa inhibits TGF. NO can be scavenged by superoxide (O(-)(2)) to form peroxynitrite, effectively reducing t...
