Our study demonstrates that the intensity of nicotine dependence, several conditions of craving for nicotine, sleep disturbances and symptoms of depression appear to be enhanced in alcohol-dependent smokers compared with non-alcohol-dependent smokers. Conclusions. - It is hoped that the factors of craving and reasons for smoking identified in this study will contribute to a better understanding of smoking temptation in alcohol-dependent smokers and non-alcohol-dependent smokers in future.
Alcohol abuse and alcoholism cut across gender, race and nationality. In general, more men than women are alcohol dependent or have alcohol problems, but women are at greater risk for adverse effects and alcohol-related diseases. Death rates among female alcoholics are 50 to 100 percent higher than those of men. Major physiological impairments, the diagnostic distribution, the psychosocial consequences and their implication on treatment will be outlined.
Objective: The primary aim of this paper was to compare the effects of flupenthixol and risperidone on subjective quality of life and attitude towards medication in chronic schizophrenic patients with mainly negative symptoms. In a spectrum ranging from its typical end ‘haloperidol’ to its atypical end ‘clozapine’, flupenthixol has typical and atypical characteristics. Methods: The effects of flupenthixol versus risperidone were investigated in a multicenter, double-blind trial, whereas subjective quality of life was assessed by means of the EuroQuol-Visual Analogue Scale and the patient satisfaction questionnaire. The attitude towards medication was assessed by means of the Drug Attitude Inventory-30 (DAI-30). Results: Mean daily dose of study medication was 6.6 (SD 2.9) mg/day flupenthixol and 3.6 (SD 1.2) mg/day risperidone. Both groups showed a significant improvement regarding subjective quality of life and positive attitude towards medication. Especially the categories ‘control of their thoughts’, concentration and ‘feeling better in general’ ameliorated in both groups. In the flupenthixol group, the ‘ability to cope with stress’, ‘feel more relaxed’ and the ‘ability to achieve something’ improved significantly more than in the risperidone group. Conclusions: (1) The spectrum of schizophrenia can be treated effectively with different neuroleptic treatments. (2) Flupenthixol especially improves the ability to cope with stress, the ability to achieve something and feeling more relaxed. (3) Subjective quality of life significantly increased with no difference between the groups.
Nicotine and alcohol dependence is common among young males. Biological assessment of illicit drug use seems to confirm previous questionnaire-based findings of associations between THC use and other illicit drugs. Urine testing seems to be an adequate method to analyse associations of THC use and other illicit drugs. In combination with questionnaires urine testing may be used for the assessment of associations of tobacco dependence and recent illicit drug use based on epidemiological surveys.
DNA barcoding is both an important research and science education tool. The technique allows for quick and accurate species identification using only minimal amounts of tissue samples taken from any organism at any developmental phase. DNA barcoding has many practical applications including furthering the study of taxonomy and monitoring biodiversity. In addition to these uses, DNA barcoding is a powerful tool to empower, engage, and educate students in the scientific method while conducting productive and creative research. The study presented here provides the first assessment of Marine Park (Brooklyn, New York, USA) biodiversity using DNA barcoding. New York City citizen scientists (high school students and their teachers) were trained to identify species using DNA barcoding during a two–week long institute. By performing NCBI GenBank BLAST searches, students taxonomically identified 187 samples (1 fungus, 70 animals and 116 plants) and also published 12 novel DNA barcodes on GenBank. Students also identified 7 ant species and demonstrated the potential of DNA barcoding for identification of this especially diverse group when coupled with traditional taxonomy using morphology. Here we outline how DNA barcoding allows citizen scientists to make preliminary taxonomic identifications and contribute to modern biodiversity research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
