Opis:
This study was carried out at Sabuncuoğlu Şerefeddin Vocational School of Health Services, Amasya University. In this study, the relationship between smoking habits and rage and anger of the Vocational School students was examined for identification purposes. Within the scope of this study, the survey was performed to reach 608 out of 822 students in 2015-2016. The youth socioeconomic factors influencing smoking, cultural characteristics, as well as peer influence, emulation, school failure, loneliness, alcohol and drug use, social students' range and anger along with psychological factors, such as stress were analyzed cross-sectionally. The demographic questionnaire used for the data collection, information about smoking habits and the anger-anger scale were used. The independent variables were age, gender, type of school, parents' educational level, parental occupational status, income, and income perception. The reasons for smoking initiation, trying, quitting and continuing to smoke of smokers and non-smokers and anger styles related to these reasons were compared. Consequently, in our study, the smoking habits of males have been found more pronounced when compared to females. However, no significant relationship was found between the smoking habits and the anger-anger style. The age of smoking initiation has been determined to be proportional to the beginning of adolescence. This study will shed light on possibilities of smoking prevention and will facilitate quitting of smoking.

Opis:
Clinically significant grapefruit juice-drug interactions are an interesting development in the last ten years of research process in the scope of drug interactions. In 1989 a group of Canadian researchers found incidentally that grapefruit juice, used as a carrier system, interacts with some calcium channel blockers, while applying alcohol during a study on alcohol-drug interactions, and presented it in Lancet as a "short report". In this report it is stated that this effect of grapefruit juice is specific and there is no similar interaction with orange juice. The grapefruit juice interactions with drugs and changes in drug pharmacokinetics, individual responses to grapefruit juice in the relationship between the drug concentration and the effect began to gain a larger clinical significance. Drugs interacting with grapefruit juice are metabolized by cytochrome P450 enzyme system in liver or intestinal section. Flavonoids contained in grapefruit juice inhibit the enzyme, bind as a substrate to the enzyme system and disrupt its bioavailability. Naringin is an essential bioflavonoid in the grapefruit juice. Naringin is not a potent inhibitor of cytochrome P450, but it is partly metabolised to "Naringenin" by intestinal bacteria. This substance is a powerful inhibitor of cytochrome P450 and it is believed by some researchers, that these are components responsible for the effect of grapefruit juice. In 2008 the number of drugs that can cause danger when taken together with grapefruit was 17. It has been reported that this number has risen to 43 in 2012. However, while the research of the possible effects of other not yet identified components of the grapefruit juice is still in progress, FDA has begun to put cautionary statement to many drug prescriptions.

Opis:
Maritime students spend a certain period of their training on board, depending on their qualifications. Deck officer candidates (deck cadets) must perform an open sea internship on commercial vessels for one year. Deck officers are among to member of crew with important responsibilities to cooperate with the Master during voyage including being involved in navigation and port watches as well as maintenance of the ship and its safety equipment. Deck cadets perform their practical training between academic education periods according to general practice in Turkey. They can be subjected to unusual working hours and rest periods during the mission on the ship. Considering the importance of adequate sleep for productivity, vigilance, sustaining attention and even over-all health and well-being, it is not only sleep quantity but sleep quality is critical. The aim of this study was to investigate of the effect of the long-term onboard training (aprox. 7 months) on the sleep quantity and quality of the maritime students. Data regarding sleep quantity and perceptive quality among the subjects were obtained by using Pittsburg Sleep Quality Index (PSQI). PSQI is a scale providing information on type and violence of sleep disorders and the quality of sleep during the past month. A total of 60 maritime students were asked to fill PSQI before and after onboard training. Demographical information such as age, gender, weight, height and information regarding the internship were also obtained. Of the students 43.3% rated as poor sleeper before the internship and this ratio increased to 73.3% after the internship. A prominent decrease in sleep quality was determined. Sleep duration did not change significantly. This study showed a significant negative effect of onboard training on sleep quality among participants and they did not recover within a month after returning from the sea which indicates potential long term consequencies.

Opis:
In this study, inhibitor effects of thymol and carvacrol were investigated in vivo and in vitro on acetylcholinesterase enzyme of Drosophila melanogaster. IC₅₀ values, Ki constants and inhibition types were determined for the substances displaying inhibitory effect. In vivo studies, were performed on larvaes by considering IC₅₀ values. The surviving and mortality rates were determined for the solution applied to larvaes. IC₅₀ values of thymol and carvacrol were found to be 25 mM and 0.175 mM, respectively. By using Lineweaver-Burk graphs, it was found that both compounds show non-competitive type of inhibition. According to results, it was concluded that carvacrol is a more effective inhibitor than thymol. We believe that these findings will contribute to the development of more potent, specific and effective inhibitors against AChE enzyme, design of new drugs for treating Alzheimer's disease and studies in pharmacological applications.
