The comparative approach has proved important many times in understanding renal function and continues to offer possible approaches to unsolved problems today, in three general areas. (1) Quantification of glomerular ultrafiltration. In contrast to the complex capillary network in the mammalian glomerulus, the glomerulus of the superficial loopless (reptilian-type) avian nephrons consists of a ...

The improved capacity to acquire quantitative data in a clinical setting has generally failed to improve outcomes in acutely ill patients, suggesting a need for advances in computer-supported data interpretation and decision making. In particular, the application of mathematical models of experimentally elucidated physiological mechanisms could augment the interpretation of quantitative, patien...

Many animal populations are in decline as a result of human activity. Conservation practitioners are attempting to prevent further declines and loss of biodiversity as well as to facilitate recovery of endangered species, and they often rely on interdisciplinary approaches to generate conservation solutions. Two recent interfaces in conservation science involve animal behavior (i.e., conservati...

considering the emphasis of islam on the importance of fasting, muslims attempt to fast from dawn until sunset during the holy month of ramadan. fasting is associated with several benefits for normal and healthy individuals. however, it could pose high risks to the health of diabetic patients due to certain physiological changes. this study aimed to compare the physiological changes associated ...

labor is a physiological event involving a sequential, integrated set of changes within the myometrium, deciduas, and uterine cervix that occur gradually over a period of days to weeks. biochemical connective tissue changes in the uterine cervix appear to precede uterine contractions and cervical dilation, and all of these events usually occur before rupture of the fetal membranes. in other wor...
