The importance of the study is that it points to a possible role of common mechanisms triggered by iron and paraquat as importan...JCI table of contents: June 21, 2007
...ly occurs when increased fluid pressure in the eye damages the optic nerve. However, in a significant subset of glaucomas elevated intraocular pressure (IOP) is not a symptom [e.g. in normal tension glaucoma (NTG)] and in other cases a reduction in IOP does not prevent disease progression. In a study appeari...NIAID supports research into etiology of fungal-induced inflammation in chronic sinusitis

... emergency rooms to treat methamphetamine overdose damages nerve cells in an area of the brain known to regulate movement, a new study shows. The findings, derived from experiments with rats, indicate that only the combination of the medication, haloperidol, and methamphetamine causes the destructive effec...Endogenous cannabinoids linked to fetal brain damage imposed by maternal cannabis use
...ke us closer to understanding if and when cannabis damages the fetal brain. Endogenous cannabinoids use the same mechanism, engaging the CB1 cannabinoid receptor, as THC to exert their effects on nerve cells. Therefore, the finding that endogenous cannabinoids control the establishment of connections amongst...Caspase-14 protects our skin against UVB and dehydration

...et radiation. Ultraviolet radiation in sunlight damages the DNA in skin cells. If left unrepaired by the cell, this damage can turn into mutations that lead to cancer. Before cells divide, they must replicate, or copy, their DNA to form new daughter cells.
