OBJECTIVE To review the clinical evidence supporting complementary and alternative medicine interventions for treating major depressive disorder. QUALITY OF EVIDENCE PubMed was searched from January 1966 to February 2010 using the term depressive disorder in combination with St John's wort, S-adenosylmethionine (SAM-e), exercise, acupuncture, omega-3 fatty acids, and folate. Only relevant hum...

A colorimetric method is presented for the quanti tat ive determination of dimethyl sulfide (DMS) in water, wort, and beer. The method is based on the formation of a complex between DMS and sodium nitroprusside. The DMS-sodium nitroprusside complex which is formed under alkaline conditions turns pink when the solution is acidified. The pink complex has an absorption maximum at 520 nm. Details o...

The lager brewing yeast Saccharomyces pastorianus, an interspecies hybrid of S. eubayanus and S. cerevisiae, ferments maltotriose, maltose, sucrose, glucose and fructose in wort to ethanol and carbon dioxide. Complete and timely conversion ("attenuation") of maltotriose by industrial S. pastorianus strains is a key requirement for process intensification. This study explores a new evolutionary ...

Extracts of the medicinal plant St. John's wort (Hypericum perforatum) are widely used for the treatment of affective disorders. Hyperforin, a constituent of St. John's wort, is known to modulate the release and re-uptake of various neurotransmitters, an action that likely underlies its antidepressive activity. We now report that hyperforin also has N-methyl-D-aspartate (NMDA)-antagonistic effe...

Brief intermittent episodes of ischemia and reperfusion, at the onset of reperfusion after a prolonged period of ischemia, confer cardioprotection, a phenomenon termed "ischemic postconditioning" (Postcond). We hypothesized that this phenomenon may just represent a modified form of reperfusion that activates the reperfusion injury salvage kinase (RISK) pathway. Isolated perfused rat hearts were...

The Evolution of Increased Competitive Ability (EICA) hypothesis predicts that introduced plants should lose enemy resistance and in turn evolve increased size or fecundity. We tested the first prediction of this hypothesis by growing introduced North American and native European genotypes of St. John’s Wort (Hypericum perforatum) in common gardens in the state of Washington, USA, and in Girona...

swallow wort is a perennial weed which has caused damage in agricultural fields in iran especially in orchards. therefore, an experiment was conducted during 2009-2011 in order to its integrated management in arachis orchard in abyek based on randomized complete block design with three replications and 18 treatments. the treatments included gramaxon (paraquat 20% sl), roundup (glyphosate 41% sl...
