Researches of Yield and Quality Characteristics of Lavandin (Lavandula X Ä°ntermedia Emeric Ex Loisel) Under Continental Type of Climate

This study was carried out in Lavandin (Lavandula x intermedia Emeric ex Loisel) planted in the farmers' land in Kayseri, Turkey in 2015-2017. Kayseri is a region with a continental climate in Turkey's Central Anatolia Region. In this study, dry flower weight, essential oil content, essential oil yield, and essential oil components were investigated in demonstrations established in 14 locations in Kayseri. Accordingly, in Lavandin, with dry flower weight of 30-127 kg ha-1, the essential oil content was 2.72-9.00% and the essential oil yield was found between 17-77 lt ha-1. A total of 37 components were identified in the essential oil analysis including linalool (37.59-50.48%), linalyl acetate (1.10-40.23%), 1.8 cineole (2.09-17.72%), and camphor (4.13-9.21%). In Lavandin (Lavandula x intermedia Emeric ex Loisel) cultivation studies in the Kayseri, altitude below 1350-1400 m positive results were obtained in the region

Evaluation of Etiological Factors in Patients with Chronic Urticaria

In the last few decades, increasing understanding of the pathomechanisms involved in chronic urticaria has highlighted the heterogeneity of different subtypes, and chronic urticaria is now classified as chronic spontaneous urticaria and inducible urticaria. Although many factors are thought to be involved in chronic urticaria, the etiology is yet to be clarified. The purpose of this study was to investigate etiological factors in patients with chronic urticaria.Five hundred patients with chronic urticaria, 351 women and 149 men, were studied for etiological factors. The autologous serum skin test was performed on 197 patients. Provocation testing for physical urticaria was performed on 354 patients. Patients with acute urticaria were excluded from the study.  We determined at least one focus of infection that might be involved in the etiology of the disease in 18.8% of cases. Patients with infections were treated, and symptoms resolved after treatment in six cases (5.3%). Autologous serum skin tests were positive in 125 patients (63.5%). Provocation tests for physical urticaria were positive in 131 (37%) patients with urticaria. We suggest that physical stimuli and autoantibodies play an important role in the etiopathogenesis of urticaria.</p

Airway Management during Pregnancy and Labor

Pregnant women undergo non-obstetric surgeries as well as cesarean operations. Airway management can be complicated due to physiological changes which occur in the respiratory system of labors. The most common causes of pregnancy-specific hypoxic respiratory failure are eclampsia, preeclampsia, and pulmonary edema that develops secondary to tocolytics. Approximately 10–15% of pregnant women undergo emergency cesarean section. Regional anesthesia is a preferred technique worldwide most commonly, and general anesthesia is applied with rapid sequence induction for the rest of the patients. Difficult Airway Society Master Algorithm for Obstetric Patients is a useful method to manage the airway in labors

Airway Management in Accident and Emergency

Accidents are associated with airway complications. Tracheobronchial injury, pneumothorax, pneumomediastinum, atelectasis, and subcutaneous emphysema can be observed. Therefore airway management in emergency medicine requires skills and equipment. Rapid-sequence intubation, effective preoxygenation, apneic oxygenation, manual inline stabilization technique should be used properly. Rapid-sequence intubation consists of sedation, analgesia, and muscle paralysis components. Videolaryngoscopes, supraglottic and extraglottic airway devices, bougie and surgical airway tools are among training materials. A range of training materials have been described to improve providers’ understanding and knowledge of patient safety. In conclusion providing oxygenation, minimizing the risk of complications and choosing the appropriate devices constitute the airway management’s pearls

Manifold learning for image-based gating of intravascular ultrasound(IVUS) pullback sequences

Intravascular Ultrasound(IVUS) is an imaging technology which provides cross-sectional images of internal coronary vessel struc- tures. The IVUS frames are acquired by pulling the catheter back with a motor running at a constant speed. However, during the pullback, some artifacts occur due to the beating heart. These artifacts cause inaccu- rate measurements for total vessel and lumen volume and limitation for further processing. Elimination of these artifacts are possible with an ECG (electrocardiogram) signal, which determines the time interval cor- responding to a particular phase of the cardiac cycle. However, using ECG signal requires a special gating unit, which causes loss of impor- tant information about the vessel, and furthermore, ECG gating function may not be available in all clinical systems. To address this problem, we propose an image-based gating technique based on manifold learning. Quantitative tests are performed on 3 different patients, 6 different pull- backs and 24 different vessel cuts. In order to validate our method, the results of our method are compared to those of ECG-Gating method

Assessment of the relationship between a narrow fragmented QRS complex and coronary slow flow

Background: The coronary slow flow (CSF) phenomenon is a delayed antegrade progression of contrast agent to the distal branch of a coronary artery in the absence of obstructive coronary artery disease (CAD). A narrow fragmented QRS (fQRS) has been reported as a significant predictor of sudden cardiac death in patients with idiopathic dilated cardiomyopathy. The present study aimed to investigate the relationship between a narrow fQRS on the admission electrocardiogram (ECG) and CSF on coronary angiography. Methods: This study included 165 consecutive patients (112 CSF, 53 controls) who underwent first-time diagnostic conventional coronary angiography for suspected CAD. Coronary flow was quantified by thrombolysis in myocardial infarction (TIMI) frame count (TFC). The patients were divided into two groups according to the presence or absence of a narrow fQRS complex on the admission ECG. Results: Forty four patients were in the fQRS group (mean age, 52.97 ± 3.13 years). There was no difference between the two groups with respect to age, gender, body mass index, family history, hyperlipidemia, hypertension, or diabetes mellitus. The extent of CSF was significantly greater in the fQRS group compared to the non-fragmented group (p &lt; 0.001). A significant correlation was also found between mean TFC values and fQRS (p &lt; 0.001). On multivariate analysis, only CSF (p = 0.03) was a significant independent predictor for narrow fQRS, after adjustment for other parameters. Conclusions: The narrow fQRS is a simple, inexpensive, and readily available noninvasive ECG parameter that may be a new potential indicator of myocardial damage in patients with CSF.

EFFECTS OF ERYTHROPOIETIN ON THE SERUM AND LIVER TISSUE LEVELS OF COPPER AND ZINC IN RATS WITH OBSTRUCTIVE JAUNDICE EFEKTI ERITROPOETINA NA NIVOE BAKRA I CINKA U SERUMU I TKIVIMA JETRE KOD PACOVA SA OPSTRUKTIVNOM @UTICOM

Summary Background: Erythropoietin is an anti-apoptotic, anti-inflammatory, angiogenetic cytokine and has protective properties against oxidative stress. In this study we investigated the effects of erythropoietin on the le vels (serum and liver tissue) of copper and zinc in cholestatic rats. Methods: Thirty-two Wistar albino rats used in the study were divided into four groups -Group I: Sham; Group II: Erythropoietin; Group III: Obstruc tive Jaundice; Group IV: Obstructive Jaundice+Erythro poietin. After the first operation, rats were followed up for seven days and then operated for the second time. Rats were sacrificed by intracardiac blood taking, and the liver tissue samples were obtained immediately. Results: Erythropoietin reduces copper, and increases zinc levels in serum and liver tissues after obstructive jaundice (p&lt;0.05). Furthermore, it has been shown that the levels of alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, alkaline phosphatase and total bilirubin/direct bilirubin were significantly lower in Obstructive Jaundice+Erythropoietin group than Obstructive Jaundice group. Conclusions: Erythropoietin affects the changes in copper and zinc levels, thus decrea sing the liver damage biochemically in rats with obstructive jaundice. However, further investigations are needed to discover how erythropoietin therapy might reduce target organ damage in cholestatic liver cases by affecting copper and zinc levels

Volume CXIV, Number 4, November 7, 1996

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%.Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespa
