Abstract:
The purpose of this study is to evaluate the effectiveness of three interventions (individual motivational interviewing, group motivational interviewing, or nurse-led hepatitis health promotion) in reducing drug use. A randomized, controlled trial was conducted with 256 methadone maintained moderate-to-heavy alcohol-using adults attending one of five MM outpatient clinics. Drug use in the overall sample was significantly reduced from baseline to 6-month follow-up, as assessed by a 30-day recall (p < 0.0001), with a trend apparent for 6-month recall (p = 0.09). The group and individual programs revealed significant decreases in drug use at the 30-day recall.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
