Remote-control closed system invented for inserting radio-active atoms inside fullerenes

... nanomaterial is then further purified by passage through a column that traps the empty-cage fullerenes. The resulting liquid is evaporated and hydroxyl atoms are attached to the molecules so they will be soluble in biofluids. All of the steps of the process are managed remotely and the purified ...

SANYO Donates Systems Effective vs. Flu to United Nations Organization Affiliate - World Association of Former United Nations Internes and Fellows (WAFUNIF)

... tap water and electricity, there are absolutely no harmful chemicals. The electricity works as a catalyst for the salt in the tap water to create hydroxyl radicals and hypochlorous acid to destroy the protein spikes on the surface of the virus. This prevents the virus from attaching to and infecting ...

A potential drug for ischemia/reperfusion related liver injury

... with liver transplantation and major liver surgery. The production of reactive oxygen species (ROS), including superoxide, hydrogen peroxide, and hydroxyl radical, has been demonstrated in reperfusion injury. Resveratrol has been reported to have several biologic effects such as a potent antioxidative ...

Chinese Red Yeast Rice May Prevent Heart Attack

... attack were randomly selected to receive capsules containing XZK or a placebo. The XZK capsules contained a combination of lovastatin, lovastatin hydroxyl acid, ergosterol, and other components, the report said. During five years of follow-up, the researchers found that 10.4 percent of those ...

Chemical engineering researchers identify biofilms that cause infections

... can trick bacteria, but you have to do it well, and another modification does not have any effect on stopping biofilm formation. "By adding that hydroxyl group and making the 7-hydroxyindole, we turn off the bacterium's ability to talk. We short-circuit the bacterium, and it becomes less of a bad ....

Smog's Origins Get Clearer

... complex chemical reactions involving the interaction of sunlight with hydrocarbons and nitrogen oxides from vehicle exhaust. Ozone is produced when hydroxyl radicals (OH) are produced from water vapor. It was long believed that most OH radicals involved in urban ozone production were generated by the ...

New Device Developed to Eliminate Superbugs Within Minutes

... They established that in the outdoors, hydroxyl radicals produced through natural reactions ... of a flower vase that constantly generates the hydroxyl radicals. The device draws in oxygen and ... to produce a cold plasma rich in ozone. The hydroxyl radicals are generated by constantly reacting the ...

A new recovery for heart attacks

... found that under low-oxygen levels, HIF loses a hydroxyl (oxygen and hydrogen) group from a proline amino ... found under low-oxygen levels, HIF loses a hydroxyl molecule from an asparagine amino acid on this ... These drugs would prevent the binding of hydroxyl groups to the HIF protein and in turn boost the ...

Super Chow, Laced With Semi-Synthetic Vitamin E, Inhibited Spread of Cancer

... said. To improve the vitamin, derivatives have been created by swapping a hydroxyl chemical group with an acid. One is alpha-tocopheryl succinate (?-TOS), ... acid (alpha-TEA), which used acetic acid. Replacing the hydroxyl group in vitamin E helps force cancer cells to self destruct, Akporiaye ...

The Multi-Faceted Chemical Benzene

... acid will react with metals like iron and copper found in water to create hydroxyl radicals. Meanwhile, when exposed to an acidic environment found in many ... sodium benzoate breaks down into benzoic acid. When the free radical hydroxyl reacts with the benzoic acid, the carbon dioxide is removed and what is ...

Elusive Step In DNA Mutation Uncovered By Researchers

... requires more energy than seems to be available because, formally, it requires that a water molecule (H2O) split apart into a proton (H+) and a hydroxyl anion (OH-). This large energy requirement has puzzled scientists for a long time. Now the research team, led by Landman and Gary Schuster, ...

Computational Model Reveals Working of AZT in Body

... four naturally occurring deoxynucleosides, the building blocks used to make DNA. However, modified AZT molecules lack a specific chemical group (a hydroxyl group) that would allow DNA replication to continue. This results in premature termination of DNA synthesis. It is thought that the triphosphorylated ...
