Ingestion, excretion and respiration in aphids were studied using artificial diets labelled with radioactive sucrose or amino acids. The rate of ingestion of a 25 % w/v sucrose diet was 12.4 nl mg-1 h-1 and the honeydew excretion rate was 5.3 nl mg-1 h-1, about 43 % of the volume ingested during the same period. The concentration of sugars in the honeydew was equivalent to 0.53 mol l-1 sucrose ...

In acute idiopathic polyneuritis weakness of relatively sudden onset sometimes progresses swiftly to severe paralysis. And yet even severely affected patients with this disease may survive with the aid of artificial respiration and apparently recover complete motor and sensory function within several weeks. The nature of the disturbance of nerve conduction underlying this reversible loss of fun...

Organophosphorus pesticide poisoning causes tens of thousands of deaths each year across the world. Poisoning includes acute cholinergic crisis as a result of AChE inhibition, intermediate syndrome (IMS) due to neuromuscular necrosis and organophosphate-induced delayed neuropathy (OPIDN) due to inhibition of neuropathy target esterase (NTE). Standard treatment for acute poisoning involves admin...
