Background: Iron is an essential mineral for normal cellular physiology but its overload can lead to cell injury. For many years, deferoxamine injection has been used as an iron chelator for treatment of iron overload. The aim of this study is to compare oral deferoxamine, activated charcoal, and vitamin C, as an absorbent factor of Fe, in changing the serum level of iron in iron overload rats....

Results In the course of three months, 49 patients were admitted to the ICU via the ED. Average length of admission was 3.1 days. Main conditions were divided into seven subgroups; drug intoxication (n=13), respiratory insufficiency (n=11), GIhaemorrhage (n=6), high-pressure lung oedema (n=3), electrolyte disturbances (n=3), septic shock (n=3) and others (n=10). Treatments primarily used were, ...

A random, observer blind, crossover design of study was undertaken in twelve normal male volunteers. Both propranolol (40 mg) and atenolol (50 mg) in single dose oral administration had significantly reduced the heart rate, systolic blood pressure and the value for double product under resting and postexercise conditions compared to the corresponding pretreatment values. Orally administered act...

We introduce a class of discrete-continuous percolation models and an efficient Monte Carlo algorithm for computing their properties. The class is general enough to include well-known discrete and continuous models as special cases. We focus on a particular example of such a model, a nanotube model of disintegration of activated carbon. We calculate its exact critical threshold in two dimension...

The invasion success of introduced plants is frequently explained as a result of competitive interactions with native flora. Although previous theory and experiments have shown that plants are largely equivalent in their competitive effects on each other, competitive nonequivalence is hypothesized to occur in interactions between native and invasive species. Small overlap in resource use with u...
