RESUMEN
The aim of this study was to identify and quantify the phenolic composition of Turanecio hypochionaeus Bosse and determine the anti-urease, anti-lipase, antidiabetic, anti-melanogenesis, antibacterial, and anti-Alzheimer properties. IC50 results for all enzymes were obtained between 0.234-116.50â µg/mL and this plant inhibited HMG_CoA R and glucosidase enzymes more with IC50 values of 0.234 and 116.50â µg/mL, respectively. Among the 11 secondary metabolites identified in T.â hypochionaeus extract, chlorogenic acid 255.459±1.17â µg g-1 ), benzoic acid (56.251±1.98â µg g-1 ), and catechin (29.029±0.27â µg g-1 ) were determined as the most abundant phenolic compounds. According to the results of the tested microorganisms, the plant extracts showed antimicrobial and antifungal properties in a dose-dependent manner. In molecular docking study, the interactions of active compounds extracted from Turanecio hypochionaeus plant and showing activity against diverse metabolic enzymes were examined. The most active compound 1, (chlorogenic acid) has -12.80, -12.80, -12.60 and -12.00â kcal/mol binding energy value against HMG_CoA R, and α-amylase, α-glucosidase, and lipase, respectively.

INTRODUCTION: This research was conducted to determine the views and information of the society about smoking cessation services and to find out the smoking status. MATERIALS AND METHODS: This descriptive study was conducted at Hacettepe University Adult Hospital. The questionnaire was conducted to the participants with face to face interview techniques between the dates 3-8 August 2011 and asked about socio-demographic characteristics, smoking status and the views on smoking cessation methods and services. In the analysis, descriptive statistics, chi-square and Fisher's exact chi-square test was used where necessary. p< 0.05 was accepted for statistical significance. RESULTS: The average age of 599 individuals participated to the research was 36.95 ± 12.80 years and 56.6% were male. The participants declared their smoking status that 48.9% do not smoke, 15.9% quit smoking, 35.2% stated as still smoking. Among current smokers 60.2% thought to quit smoking in the last 12 months. Of the participants 42.1% have tried to quit smoking in the past 12 months. 46% percent of smokers and 56.3% non-smokers stated that they are aware of smoking cessation outpatient clinics (p= 0.033). The percentage of awareness of smoking cessation line was 67.8%, and 46.9% are aware of AMATEMs. Same percentages are as 49.5% and 28.4% for the ones who quit smoking. 59.7% of smokers think that nicotine-free preparates and 17.4% think that nicotine preparates is successful; these percentages are 89.7% and 36.7% for non-smokers. CONCLUSION: Tendency to cessation among tobacco users and have awareness about the services that support cessation and believe that the law reduces the harms of tobacco use. However, more interventions are needed to reach those who are at low-income level. Also being a role model to the children in the society and to use attitudes and behaviors in smoking cessation campaigns are thought to be effective.

OBJECTIVE: To evaluate the safety and efficacy of heart rate reduction by intravenous esmolol in patients who are assigned for coronary angiography with 64-slice computed tomography (CT). METHODS: Five hundred consecutive patients were prospectively analyzed. Patients with an initial heart rate less than 65 beats per minute (bpm) did not receive esmolol. Patients with a heart rate between 65 and 80 bpm received a bolus dose of 1 mg/kg intravenous esmolol. Patients with an initial heart rate between 80 and 90 bpm received a bolus dose of 2 mg/kg intravenous esmolol. An additional 1 mg/kg intravenous esmolol was given to the patients when the target heart rate was not reached with the first bolus dose. Patients with an initial heart rate more than 90 bpm received 50 mg atenolol PO, and were reevaluated after 1 h. RESULTS: A total of 391 patients with a heart rate > or =65 bpm before multislice computed tomography (MSCT) examination received intravenous esmolol with a mean dose of 158+/-55 mg. Initial and final mean heart rates were 80+/-11 bpm and 63+/-7 bpm, respectively (P<0.0001). Heart rate below 65 bpm was reached in 265 (65%) of these 391 patients. Only four patients (1%) had a final heart rate above 80 bpm before MSCT imaging. Four of the 391 patients (1%) had a final heart rate below 50 bpm. CONCLUSION: Intravenous esmolol is safe and effective to reach the optimum heart rate in patients assigned for MSCT.

BACKGROUND: Patients who had undergone complete ankle-to-groin stripping of the greater saphenous vein were evaluated retrospectively to assess the necessity of saphenofemoral junction reconstruction during the stripping procedure. Since 1996, in addition to the conventional complete stripping operation, we routinely perform a saphenofemoral junction reconstruction in patients presenting with greater saphenous vein reflux associated with low-grade (grades I-II) saphenofemoral junctional reflux. In this method, the size of the common femoral vein was adjusted to the desired diameter by a running linear suture technique after division of the greater saphenous vein. METHODS: Retrospective evaluation revealed that 73 limbs in 56 patients treated with this technique (group I). This group of patients was matched to another group of 65 patients (78 limbs) with similar characteristics and symptoms (group II) in whom the conventional complete ankle-to-groin stripping of greater saphenous vein was the treatment. The 2 groups were compared with respect to the incidence of complications, including recurrence of varicosities, ecchymosis, lymphocele, lymphorrhagia, wound infection, and paresthesia in the operated extremity. All patients also were evaluated by Doppler ultrasonography at 6 months, 12 months, and annually thereafter to determine the saphenofemoral junction reflux time (valve reflux time). The mean duration +/- SD of follow-up was 6.7 +/- 1.6 years (range, 2.1-10.8 years). RESULTS: Recurrence of varicosity was noted in 14 patients, 3 in group I and 11 in group II (P = .02). There were no statistically significant differences between the 2 groups in terms of ecchymosis, hematoma, lymphocele, lymphorrhagia, wound infection, and paresthesia. At 6 months, a rapid decrease in valve reflux time was noted in group I (P = .0001). In addition, there was a significant improvement in valve reflux time at each subsequent Doppler examination in group I. Group II showed a decrease in valve reflux time, compared with the preoperative value (P = .068). During subsequent Doppler examinations, a decrease in valve reflux time also was noted in group II; this difference reached statistical significance only at 24 months (P = .04). CONCLUSIONS: We believe that saphenofemoral junction reconstruction is a simple technique to perform and that addition of this method to the conventional stripping provides more durable results with a lesser incidence of recurrence. This method should be considered as a treatment modality in patients with greater saphenous vein reflux associated with low-grade (grades I-II) saphenofemoral junctional reflux.

Clinical significance of coronary arteries with anomalous origin and/or course is highly heterogeneous. Anomalies with the origin from the opposite sinus and interarterial course can be associated with angina, syncope, and sudden cardiac death. However, there are no clear guidelines for diagnosis and treatment of such cases. We present the case of a young lady who presented with typical angina, and later proved to have an anomalous right coronary artery (RCA) originating from the left sinus of Valsalva coursing between the aorta and pulmonary artery. This was associated with demonstrable stress ischemia with nuclear perfusion scan. The patient underwent surgery with a bypass graft to the anomalous RCA with complete relief of her angina.
RESUMEN
We have evaluated the prevalence of left main coronary artery disease (LMCAD) among patients referred to multislice computed tomography (MSCT) coronary angiography examinations. The study Group comprised of 1,000 consecutive patients (750 male and 250 female; mean age 53+/-12 years) who underwent successful 64-slice MSCT examinations. Left main coronary artery (LMCA) was classified into three Groups: normal LMCA; nonsignificant LMCAD with coronary plaques resulting in obstructions
