Agronomic and technological properties of coriander (Coriandrum sativum L.) populations planted on different dates [Farkli zamanlarda ekilen kisnis (Coriandrum sativum L.) populasyonlarinin agronomik ve teknolojik ozellikleri]
(TUBITAK, 2000) Kaya N.; Yilmaz G.; Telci I.
This research was conducted to determine suitable sowing dates and the potential productivity of coriander (Coriandrum sativum L.), grown in the Mardin, Denizli and Erzurum districts, at Tokat ecological conditions in 1997 and 1998 vegetation periods. Three local populations from Mardin, Denizli and Erzurum were sown on four different dates (1 November, 1 March, 15 March and 1 April). The highest seed yield was obtained from the Erzurum population as 908 kg/ha. The greatest essential oil ratio was recorded from the Denizli population with 0.39%. Linalool which is main component of coriander essential oil varied from 50.52-92.52. Plant height (48.6-73.2 cm), number of branches per plant (4.5-6.2), number of umbeis per plant (4.7-7.8), biological yield (2.282-3.473 t/ha) and seed yield (0.678-0.911 t/ha) were decreased by later sowing dates. The effect of sowing dates was insignificant on 1000 seed weight (7.46-7.66 g), essential oil (0.28-0.33 %), protein ratio (14.1-14.8 %) and ash ratio (6.28-6.78 %).

Previous multicenter/multinational studies were evaluated to determine the frequency of the absence of cerebrospinal fluid pleocytosis in patients with central nervous system infections, as well as the clinical impact of this condition. It was found that 18% of neurosyphilis, 7.9% of herpetic meningoencephalitis, 3% of tuberculous meningitis, 1.7% of Brucella meningitis, and 0.2% of pneumococcal meningitis cases did not display cerebrospinal fluid pleocytosis. Most patients were not immunosuppressed. Patients without pleocytosis had a high rate of unfavorable outcomes and thus this condition should not be underestimated. © 2017 The Author(s)
The effect of cannula material on the pain of peripheral intravenous cannulation in the emergency department: A prospective, randomized controlled study
(2012) Özsaraç M.; Dolek M.; Sarsilmaz M.; Sever M.; Sener S.; Kiyan S.; Yürüktümen A.; Yilmaz G.
Objectives: The present study was undertaken to compare the pain of peripheral IV cannulation (IVC) using a 20-G peripheral biomaterial PEU-Vialon cannula or the 20-G compound FEP-Teflon cannula widely used in clinical practice. Methods: A prospective, randomized, single-blinded, controlled trial was undertaken at the ED of University Hospital. Eighty-nine noncritically ill adult patients who were receiving an IV line as part of their care were enrolled. In each case cannulas were applicated to the antecubital area. Participants rated their pain on a visual analog scale (VAS). The primary outcome was patients pain score, and the secondary outcome was the provider's perception of safety and satisfaction. Results: The two treatment groups did not differ in age, gender or cannulation indication (p>0.05). Mean VAS was 2.80 for PEU and 3.56 for FEP (p=0.061). Mean provider safety scores were 4.84 (4 to 5) in the PEU group and 4.00 (2 to 5) in the FEP group (p=0.0001). Mean provider satisfaction of application scores were 4.65 in the PEU group and 4.56 in the FEP group (p>0.05). Conclusions: Althogh provider safety perception is high, perception of pain has not reduced when inserting PEU-Vialon cannula compared with compound of FEP.
Encapsulation of ?-amylase in a starch matrix
(2002) Öngen G.; Yilmaz G.; Jongboom R.O.J.; Feil H.
In this study thermostable ?-amylase was encapsulated in a pregelatinized potato starch to obtain a controlled degradation upon water uptake. Encapsulation was performed using kneading, a (thermo) mechanical process. The aim of the study was to evaluate the possibility to encapsulate a degrading enzyme for a system, which can be triggered to degrade upon water uptake instead of direct water contact. After the encapsulation process, the enzyme (?-amylase) activity in the samples was found to have 90 ± 5% of activity of the unprocessed enzyme. It was seen that there was initial degradation of the starch matrix during processing, proportional to the enzyme concentration. The encapsulated enzyme was inactive during storage under low humidity conditions (RH ? 60%) and could be reactivated upon water uptake by incubation of samples in humid atmosphere (90% RH). The reduction of the molecular weight, upon activation of the encapsulated enzyme was also proportional to the concentration of the encapsulated enzyme. © 2002 Elsevier Science Ltd.

Essential oil contents and compositions of Thymus sipyleus growing wild in Central Turkey
(2004) Yilmaz G.; Telci I.; Kandemir N.; Kaya N.
Essential oils from single Thymus sipyleus plants growing wild in Central Turkish Province of Tokat were analyzed for major constituents using gas chromatography. This area of Turkey is known for its richness of medicinal and aromatic plants. Twenty-five specimens collected from different areas of Tokat were subjected to essential oil content analyses. Essential oils were studied for eight major components (1,8-cineol, linalool, borneol, ?-pinen, ß-pinen, carvone, camphor, carvacrol). Essential oil contents varied from 0.08 to 0.82%. Eight components studied generally constitute more than 80% of the essential oils, 1,8-cineol being the predominant constituent followed by linalool and carvone. Some specimens contained about 10% of ?-pinen and 15-20% camphor. ß-pinen and carvacrol contents were 5-6% in essential oils of some specimens. Chemical compositions of our specimens were considerably different from specimens of the same species collected from western part of Turkey.
Ketofol Provides Better Upper Airway Size than Ketamine and Propofol in Pediatric Population Receiving Sedation for Magnetic Resonance Imaging [Ketofol Manyetik Rezonans Görüntüleme Için Sedasyon Alan Pediatrik Hastalarda Ketamin ve Porofole Göre Daha Genis Havayolu Açikligi Saglar]
(OrtadogÂŸu Reklam Tanitim Yayincilik Turizm Egitim Insaat Sanayi ve Ticaret A.S., 2020) Yilmaz G.; Esen O.; Aydina N.; Varolc K.; Kayhan A.; Derbentd A.; Salihoglu Z.
Objective: The present study aimed to compare the upper airway dimensions as well as hemodynamic and anesthetic features of propofol, ketamine, and ketofol in children undergoing magnetic resonance imaging (MRI) scanning. Material and Methods: This retrospective study was carried out on data derived from a total of 89 patients aged between 1-160 months who were allocated in 3 groups concerning the anesthetic agents administered during sedation for MRI. Group I received ketamine and propofol (ketofol), whereas Group II had propofol and, and Group III received ketamine in this procedure. Results: The cross-sectional area of the upper airway at the levels of the base of tongue, soft palate and epiglottis were higher in patients receiving ketofol, compared to those receiving propofol or ketamin (p<0.05). The duration of the recovery and total duration of the procedure were also significantly lower in patients receiving ketofol compared to others (p< 0.001). Systolic, diastolic, and mean blood pressures were significantly lower in children receiving propofol compared to those receiving ketamine or ketofol. Conclusion: Ketofol, which is the combination of ketamine and propofol, provides an effective and safe anesthetic regimen for magnetic resonance imaging in the pediatric population. Our results show that ketofol-based sedation also provides a larger upper airway size without the development of any hemodynamic derangement. © 2020 OrtadogÃ‚ÂŸu Reklam Tanitim Yayincilik Turizm Egitim Insaat Sanayi ve Ticaret A.S..

Background/aim: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics. Materials and methods: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician. Results: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had ?5 years of occupational experience (junior specialists = JSs) and 942 (49.4%) of them were physicians. Specialists having >5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05). Conclusion: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did. © TÜBITAK.

The place and the efficacy of infectious disease consultations in the hospitals
(2012) Erdem H.; Kurtaran B.; Arun O.; Ylmaz H.; Çelebi G.; Özkaya H.D.; Kaya S.; Birengel S.; Güner R.; Demiroglu Y.Z.; Demirdal T.; Tekin-Koruk S.; Coşkun O.; Kazak E.; Çelen M.K.; Akova M.; Timurkaynak F.; Alpay Y.; Yilmaz E.; Saçar S.; Aydin A.F.; Bodur H.; Elald N.; Inal A.S.; Saba R.; Tok D.; Agalar C.; Candevir A.; Parlak M.; Sipahi O.R.; Yilmaz G.; Koçak N.; Öncü S.; Sirmatel F.; Küçükardali Y.; Güzel-Tunçcan O.; Mete B.; Doyuk-Kartal E.; Ulcay A.; Şenol E.; Dayan S.; Leblebicioglu H.; Tabak F.; Gorenek L.; Ulusoy S.; Ayaz C.; Ergonul O.; Aksu H.S.Z.
Our study aims to determine the efficacy of infectious disease consultations and the interrelations between doctors in this social laboratory. This study was conducted at 34 centers located in 22 cities across Turkey and contributed by 210 infectious disease specialists (IDSs) and 970 non-infectious disease specialists (NIDSs), totaling 1180 medical doctors. Infectious disease specialists and NIDSs have separately contributed by responding to questionnaires designed specifically for the consultation process. It appears that a satisfactory collaboration has been established between IDSs and NIDSs during the consultation practices. There are some discrepancies in the perceptions of some of the NIDSs. These are the evaluation of patients holistically, the expectation of NIDSs in critical infection cases to start the therapy immediately, losing the support of drug companies by NIDSs, and the restriction of NIDSs in routine medical practice. On the other hand, NIDSs seem to have real problems in the diagnosis or treatment of infectious diseases. The consultation service provided by the IDSs in Turkey is widely accepted among other clinicians and appears to be of a crucial importance. Copyright © 2012 by Lippincott Williams & Wilkins.
Respiratory syncytial virus epidemiology in Turkey
(2005) Kanra G.; Tezcan S.; Yilmaz G.; Acunas B.; Aslan Ş.; Aslan Y.; Belet N.; Can G.; Cevit Ö.; Çan G.; Çetin N.; Dabak Ş.; Dagli E.; Devecioglu C.; Ergör G.; Ergül A.; Ertem M.; Eskiocak M.; Günş T.; Güraksin A.; Hacisalihoglu S.; Ince Z.; Kahveci H.; Kara A.; Karadag B.; Kirimi E.; Kumral A.; Kut A.; Küçüködük Ş.; Kültürsay N.; Metin F.; Önal S.; Örs R.; Özek E.; Özkan H.; Özmert E.; Özturanli L.; Öztürk A.; Satar M.; Taştakin A.; Tütüncüler F.; Yalaz M.; Yildizdaş H.; Yilgör E.; Yurdakök M.
Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections in infants and young children worldwide. This study was conducted to determine the prevalence of RSV among high-risk children admitted with respiratory symptoms in a developing country. This is a multicenter study conducted among children less than 24 months of age and admitted to the hospital with respiratory symptoms. The inclusion criteria included: lower respiratory tract symptoms on admission, gestational age less than 35 weeks, and admission age less than six months, or children less than 24 months of age with a diagnosis of bronchopulmonary dysplasia requiring medical treatment or intervention during the last six months or with an uncorrected congenital heart disease (other than patent ductus arteriosus). Nasopharyngeal samples were obtained with one of the three standard methods: nasopharyngeal aspirate, nasopharyngeal wash or nasopharyngeal swab. RSV antigen was determined by enzyme immunoassay using Abbott TESTPACK RSV (No. 8100/2027-16). Statistical analysis was performed using Student's t-test and chi-square test. In this study, 332 children (135 females, 40.7%; 197 males, 59.3%) were included, and the nasopharyngeal specimens of 98 (29.5%) children were determined to be RSV-positive. There were no differences in sex, age of gestation, age of admission, family education, number of siblings and smoking at home for RSV-positive and -negative cases. Furthermore, underlying disease and duration of hospital and intensive care unit stay were similar among groups. Only otitis media was more common among RSV-positive cases. No fatality at hospital was recorded. Frozen samples revealed more negative results. Most cases presented during winter and the number of RSV-positive cases was higher in cold and economically poor areas. Premature children and children with underlying medical con dition acquire RSV irrespective of other sociodemographic risk factors, and most of them are hospitalized. Thus, an RSV vaccine seems the most effective mode of protection to decrease morbidity and mortality.
