This paper draws on recent ethnographic fieldwork projects among mobile professionals in three overlapping settings: in the midst of inter-city business travel; conducting work while roaming within a more restricted urban or rural periphery; and within the confines of a single plant or office building. Spanning all these situations were a set of tensions(More)
Membrane currents and resting potential of isolated primary mouse articular chondrocytes maintained in monolayer cell culture for 1-9 days were recorded using patch clamp methods. Quantitative RT-PCR showed that the most abundantly expressed transcript of voltage-gated K(+) channels was for K(V)1.6, and immunological methods confirmed the expression of(More)
We investigated the neuroprotective properties of two M-type K+ channel blockers, linopirdine and its analog XE991, in rat sympathetic neurons deprived of nerve growth factor (NGF). Linopirdine and XE991 promoted sympathetic neuronal survival 48-72 hr after NGF withdrawal in a concentration-dependent manner. Both drugs prevented neuronal apoptosis by(More)
We examined changes over 28 days in mood states, craving for cocaine, and sleep during short-term abstinence reported by 12 male, predominantly intravenous-using, cocaine-addicted subjects residing in a research facility. For comparison, we examined 10 nonaddicted control subjects. There were no significant differences between cocaine addicts and controls(More)
BACKGROUND Little is known about outcomes of community-based treatment programs for adolescents with drug problems. METHODS We studied 1167 adolescents (age range, 11-18 years; 368 females, 799 males) from 4 US cities (Pittsburgh, Pa; Minneapolis, Minn; Chicago, Ill; and Portland, Ore) using a naturalistic, nonexperimental evaluation design. These(More)
We conducted a single-blind, random assignment, placebo-controlled, 12-week comparison of desipramine hydrochloride and amantadine hydrochloride as adjunctive treatments to counseling for cocaine dependence. Subjects were 54 outpatients who met DSM III-R criteria for active cocaine dependence and who completed a minimum of 2 weeks of treatment. Subjects(More)
We conducted a pilot study (N = 22) comparing the efficacy of desipramine and amantadine for treatment of cocaine dependence in methadone maintenance clients. The study which lasted 12 weeks, was double-blind, randomly assigned, and placebo-controlled. Subjects met DSM-III-R criteria for active cocaine dependence. All three groups' cocaine use, craving, and(More)
This study examined correlates of high (HCA) and low (LCA) cognitive ability among substance dependent individuals who participated in an ongoing study of early engagement strategies. Participants (55% male; 98% African American), were administered the ASI, Shipley Institute of Living Scale, Beck Hopelessness scale, and TCU Motivation Scales at intake.(More)
