Chilling-Enhanced Photooxidation

Chilling-Enhanced Photooxidation : The Peroxidative Destruction of Lipids during Chilling Injury to Photosynthesis and Ultrastructure.

Chilling-induced photooxidation was studied in detached leaves of chilling-sensitive (CS) cucumber (Cucumis sativus L.) and chilling resistant (CR) pea (Pisum sativum L.). The rates of photosynthesis and respiration, measured as O(2) exchange, were found to be comparable in the two species over a temperature range of 5 to 35 degrees C. Chilling at 5 degrees C for 12 hours in high light (1000 mi...

Accelerated Chilling and Packaging Effects on Enhanced Beef Round Muscles

Chilling out

Climate warming has forced the distribution of several fish stocks in one of Europe's major fishing grounds many kilometres north or to greater depths to find cooler waters, according to a study by climate change scientists. The distribution of major fish species, including cod and haddock, has shifted in response to an average 1 o C rise in the temperature at the bottom of the North Sea over t...

Photooxidation by Pteridines'

Suinizary. A nunibl)er of pteridfines were examined( for activity in promotinig photop)hosphorylation in broken spinach chlioroplasts anid in stimlulating cvtochrome c photooxidation ill sonicated chloroplasts. Correlation was fouind between activities for the 2 reactions. Photophosphorylation promoted by pteridines was inhibited by DCMU and by anaerobic conditiolns. It is concluded that pterid...

Enhanced photooxidation sensitizers: the first examples of cyclometalated pyrene complexes of iridium(III).

The iridium(III) cyclometalation of alkylated pyrene-benzimidazole ligands proceeds in an unprecedented manner. The resultant complexes display remarkably enhanced photooxidation capabilities using 1,5-dihydroxynaphthalene as a substrate.
