Kinetics of Secondary Reactions Affecting the Organosolv Lignin Structure.

Many valorization approaches for lignin rely on its organic solvent (organosolv) extraction. However, the severity of the extraction conditions required to obtain high lignin extraction generally results in low-quality lignin for downstream processing. To better understand the secondary reaction pathways and kinetics related to molecular alterations that result from organosolv extraction under extreme conditions, extractions were conducted at temperatures of 150, 180, and 210 °C.

Bupropion and nicotine patch as smoking cessation aids in alcoholics.

This is a double-blind placebo-controlled study of sustained-release bupropion as a smoking cessation aid in alcoholics undergoing treatment for their alcoholism. Participants (N=58) were enrolled within 1 week of entry into alcohol treatment from community and Veterans Affairs Substance Use Disorder programs. All participants received nicotine patch and were invited to attend a smoking cessation lecture and group.

Methamphetamine use in rural Midwesterners.

Methamphetamine use has been characterized as a "rural" drug; however, little is known about rural methamphetamine use disorders (MUD). This study describes and compares characteristics of rural and urban patients with MUD. Rural study participants reported earlier first regular use of methamphetamine, more alcoholism, more intravenous use, and a greater number of cigarettes/day, and were more likely to report methamphetamine-related psychotic symptoms.
