ELECTRON STAINING WITH URANYL ACETATE POSSIBLE ROLE OF FREE AMINO GROUPS

Localization of crystals in diseased oats treated with uranyl acetate.

Uranyl acetate, a suppressor of victorin-induced electrolyte leakage in oat leaves when applied together with, or before, victorin, also suppressed victorin-induced changes in ultra-structure. Uranyl crystallized in cell walls and near the plasmalemma of vascular cells, but was excluded from the protoplasm. Fewer crystals occurred near the plasmalemma when leaves were allowed to take up uranyl ...

The free amino groups of haemoglobins.

No evidence has been found to show that the protease is a mixture ofenzymes or that the protease of one plant is distinguishable from another. It has been customary to name a protease after the generic name of the plant in which it is found. This custom, both here and in future work, implies an indefinite extension in the number of proteases. It is therefore recommended that the proteases descr...

The free amino groups of insulin.

Photooxidation of cellulose acetate and cellobiose by the uranyl ion.

The photooxidation of cellulose acetate by uranyl nitrate in acetone solutions has been investigated. Studies of the effect of the polymer on the uranyl luminescence showed an initial increase in intensity, followed by quenching. This is interpreted in terms of competition between complexation of uranyl ions by the polymer and dynamic quenching. In the quenching region, Stern-Volmer kinetics ar...

Free Radical Scavenging Activity of Silymarin with Refrence to Depleted Uranium Induced Mitochondrial Dysfunction

Introduction: Recently depleted uranium is being widely used as anti-armour ammunition and at very high temperature, results in information of an aerosol of very small uranium oxide particles, which may be inhaled. It is alleged that these particles represent a new battlefield hazard because of the chemical toxicology and/or radioactivity. Method & materials: Male Wistar strain albino rats ...
