As a result of these dynamics, boys with more fatalistic beliefs

As a result of these dynamics, boys with more fatalistic beliefs may report more conflict and less cohesion. Moreover, youth who feel disillusioned and hopeless about the future may have a general pessimistic view of the world. They may also be more apt to focus on negative experiences such as discrimination and family conflict and report more of inhibitor licensed these instances (regardless of whether they experience more discrimination and family conflict) compared with youth with a more positive cognitive style.

Nicotine is considered the major component of tobacco smoke responsible for addiction (Stolerman & Jarvis, 1995). In the context of medications development to aid smoking cessation, the current issue of the Diagnostic and Statistical Manual of Mental Disorders (DSM�CIV) addresses two major conditions related to tobacco use: nicotine-use disorder and nicotine-induced disorder.

Nicotine-use disorder is characterized by the gradual development of tolerance to many of the physiological effects of nicotine; the use of tobacco products in larger amounts or over a longer period than intended; persistent desire to smoke or unsuccessful attempts to cut down on tobacco; a great deal of time spent in obtaining or using tobacco; social, occupational, or recreational activities being reduced because of tobacco use; and tobacco use continuing despite physical or psychological problems caused or exacerbated by tobacco. Cessation of tobacco use triggers the expression of an aversive nicotine withdrawal syndrome (Kenny & Markou, 2001).

Nicotine-induced disorder (withdrawal) is defined by the DSM-IV as a condition manifested in an individual after cessation of tobacco consumption after a period of at least several weeks of daily nicotine use, followed within 24h after abrupt cessation or reduction of use. Symptoms of nicotine withdrawal include dysphoric or depressed mood; insomnia; irritability; frustration or anger; anxiety; difficulty concentrating; restlessness; decreased heart rate; and increased appetite or weight gain. All current FDA-approved medications for tobacco dependence are approved for the indication ��aid to smoking cessation,�� with the primary endpoint in clinical trials generally being 4 weeks of continuous abstinence from tobacco consumption. All approved smoking-cessation medications have been shown to reduce nicotine consumption in preclinical or clinical assessments, reflecting diminished reinforcing properties of nicotine that likely explains the clinical efficacy of these Batimastat compounds (Aubin et al., 2008; George, Lloyd, Carroll, Damaj, & Koob, 2011; Levin et al., 2012).
