International Journal of Emergency Medicine , 2012, DOI: 10.1186/1865-1380-5-5
Abstract: For slimming, the use of weight loss pills flavored with Mexican pepper seeds is common among females. Originally called "La Jiao Shou Shen," cayenne (chili) pepper pills have been imported to Turkey from the Far East. China and Russia are the only countries in the world where chili pepper pills are sold. Capsules containing 400 and 600 mg of chili pepper are sold for weight loss; patches and gels are used for pain relief and slimming, respectively [1].Cayenne pepper pills contain pungent ingredients called capsaicinoids, and one of the active components of cayenne pepper is capsaicin [2]. Capsaicin accelerates energy expenditure and suppresses body fat accumulation by activating the sympathetic nervous system (SNS) in animals and humans [3-6]. However, this substance is associated with cardiotoxicity, including coronary vasospasm, supraventricular tachycardia, and acute atrial fibrillation [1,7]. Capsaicin also prolongs the cardiac action potential in atrial and ventricular myocytes, an effect that is associated with the inhibition of potassium currents [8,9]. Coronary vasospasm and acute myocardial infarction (AMI) associated with the use of topical capsaicin patches to relieve back pain have been reported recently [7]. Here, we describe the first reported case of coronary vasospasm and AMI suspected of being caused by the use of cayenne pepper pills for slimming.A 25-year-old male was admitted to our emergency department complaining of severe chest pain 2 h after its onset. The pain radiated to the ulnar aspect of the patient's left arm, neck, and jaw. An electrocardiogram (ECG) demonstrated an ST-segment elevation of 7 mm in leads II, III, and aVF, consistent with an inferior wall AMI (Figure 1). A bedside transthoracic echocardiogram showed a non-dilated left ventricle with inferior hypokinesia, confirming a recent myocardial infarction. On physical examination, the patient was conscious but extremely anxious. His blood pressure was 90/55 mmHg, pulse rate 62 be

Abstract: Objective: Coronary artery ectasia (CAE) is a congenital or acquired anomaly characterized with localized or diffuse dilatations of coronary arteries. Paraoxonase (PON-1) is a high-density lipoprotein-cholesterol (HDLC) associated antioxidant enzyme that prevents atherosclerosis. The aim of this study was to investigate serum paraoxonase-1 enzyme activity (SPA) in patients with CAE in comparison patients with coronary artery disease (CAD) and normal coronary arteries. Methods: We have evaluated 44 patients with isolated IKAE, 40 cases with normal coronary arteries (NCA), 40 cases with critical CAD (CAD) and 40 cases with minimal CAD (MCAD) in this cross-sectional observational study. Demographic and biochemical data of patients were collected. SPA was determined spectrophotometrically. Among-group comparisons, ANOVA, Kruskal-Wallis and Chi-square tests were used; Bonferroni test was used for post-hoc analysis, Pearson's correlation analysis to determine the parameters associated with the SPA. Results: There were no differences among groups with regard to age, sex, presence of diabetes, hypertension and smoking (p>0.05 for all). The highest HDLC was detected in patients with NCA and lowest HDLC was detected in patients with CAD (respectively 52±15 mg/dL; 41±16 mg/d L, p=0.021). CAD and CAE groups were similar with respect to HDLC levels (p>0.05). The highest SPA level was detected in patients with NKA and the lowest SPA level was detected in patients with CAD (respectively 250.78±59.37U/L; 163.39±49.28 U/L, p=0.005). CAD and CAE groups were similar with respect to SPA levels (p>0.05). Conclusion: Both decreased SPA and decreased HDLC levels are closely related to the development of the CAE similar to CAD.

Buildings , 2013, DOI: 10.3390/buildings3010173
Abstract: Reinforced concrete buildings suffered significant damage in the region affected by the 29 May 2011 earthquake in Simav (Kutahya), Turkey. Typical building damage is classified and potential causes of damage are investigated. Reinforced concrete moment resisting frames with hollow brick infill walls are the most common structural system in and around the Simav city center while masonry construction is common in rural areas. Although the Simav earthquake, with a magnitude of 5.7 to 5.9, can be classified as a moderate earthquake, many buildings experienced damage varying from frequent diagonal cracking and brittle failure of infill walls to collapse or severe damage to frames due to short columns, soft stories or other reasons including insufficient or poor detailing of reinforcement. This study investigates and presents the seismicity of the region, characteristics of the measured ground motions, seismic load demands including response spectra, and damage mechanisms, potential causes and classification of observed damage in reinforced concrete buildings.

Physics , 2014,
Abstract: I summarize the status of the inclusive SUSY searches conducted by the ATLAS and CMS experiments using the 20 fb-1 of 8 TeV LHC data in the all inclusive, 0 lepton, >=1 lepton and >=2 lepton final states. Current searches show that data are consistent with the SM. The impact of this consistency was explored on a rich variety of SUSY scenarios and simplified models, examples of which I present here.

Seyhan Ozturk, Halil Kutuk
International Journal of Organic Chemistry (IJOC) , 2011, DOI: 10.4236/ijoc.2011.14029
Abstract: In this study, several N-(p-substituted-arylsulfonyl)phthalimides (1a-e) were synthesized. The synthesized compounds were then examined with respect to their substitution reactions with t-butylamine, diethylamine, cyclohexylamine, and trans-1,2-diaminocyclohexane in acetonitrile. In order to determine the mechanism, substituent effect, activation entropy, and nucleophile effect were used as criteria.
