We compared the cryoprotective ability of glycerol and polyethylene glycol (PEG) during freezing. Isolated rat hearts were flushed with one of three cardioplegic solutions (CP-14, CP-15, and CP-16), frozen at -1.4 degrees C, and reperfused after thawing to assess function. After 3 h freezing, cardiac output (CO) in CP-14-flushed hearts recovered to 58.1% of control. CP-16 (CP-14 with 5% PEG) im...

Background. We have previously shown that increasing myocardial carnitine levels in fatty acidperfused isolated working rat hearts dramatically increases glucose oxidation rates. Since high levels of fatty acids depress reperfusion recovery of ischemic hearts by inhibiting glucose oxidation, we determined what effect carnitine has on glucose oxidation during reperfusion of ischemic hearts. Meth...

background trauma constitutes a major public health problem in our country and contributes significantly to unacceptably high morbidity and mortality. objectives this study aimed to evaluate the epidemiology of trauma in dead patients referred to shahid rajaee trauma hospital, shiraz, iran. patients and methods in a cross-sectional study, all patients with trauma admitted to our center were enr...

Alterations in glucose metabolism have been implicated in the cardiovascular complications of diabetes. Previous work in this laboratory demonstrated that hearts from diabetic animals have an elevated cytosolic redox ratio (NADH/NAD+) and that this redox imbalance is probably due to elevated polyol pathway flux. We therefore hypothesized that 1) the elevated cytosolic redox ratio of diabetic he...

If we are on the outside, we assume a conspiracy is the perfect working of a scheme. Silent nameless men with unadorned hearts. A conspiracy is everything that ordinary life is not. It’s the inside game, cold, sure, undistracted, forever closed off to us. We are the flawed ones, the innocents, trying to make some rough sense of the daily jostle. Conspirators have a logic and a daring beyond our...

ACKNOWLEDGEMENTS Time flies! Four years went away like a snap of the fingers. Yet, it has been a happy, fruitful journey, with outstanding education from which I will continuously derive benefits and cheerful memories that I will always cherish in my life time. Along this journey, many people and friends stood by my side, providing me guidance, help, and supports. I would like to take the chanc...

This paper investigates the approximation behaviour of the KH interpolative fuzzy controllers. First, in accordance with the remarks in [20], it is pointed out that it is a fuzzy generalization of the Shepard operator. Shepard operator has thoroughly studied by approximation theorist since the mid 70s. Exploiting the aforementioned relationship, we establish analog results on the approximation ...

in the current study, effects of acute short term administration of fructose on cardiac arrhythmias and myocardial infarction size following ischemia/reperfusion were investigated in isolated rat heart. the hearts were subjected to 30 min zero flow global ischemia followed by 120 min reperfusion. in the control group, the hearts were perfused by normal drug free krebs-henseleit (k/h) solution t...

Isolated rat hearts were perfused with hormonal concentrations of glucagon during a hypoxic perfusion to determine whether it would enhance recovery after reoxygenation. Rat hearts were divided into two groups: (1) those perfused with glucose-free Tyrode's solution and (2) those perfused with Tyrode's solution containing glucose. During 3 minutes of exposure to hypoxia both untreated hearts and...

In this study, the formation of hydrogen peroxide (H2O2) by chilled goat spermatozoa was measured. Furthermore, the effects of dead spermatozoa on motility characteristics were studied. Fresh collected ejaculates from five Shami bucks were centrifuged and virtually all seminal plasma was removed. A part of the collected spermatozoa was killed by two ways: the first by repe...
