Öğe Age and Body Size of the Mediterranean Chameleon, Chamaeleo chamaeleon (Linnaeus, 1758) (Lacertilia: Chamaeleonidae) Specimens Collected from Adana, Türkiye(ABADER (Adıyaman Bilimsel Arastırmalar Dernegi), 2022) Yildirim E.; Beşer N.; Yilmaz C.; Candan K.; Kumlutaş Y.; Ilgaz Ç.; Najafi Majd E.Age structure and body size of the Mediterranean Chameleon, Chamaeleo chamaeleon (Linnaeus, 1758) specimens collected from Akyatan, Adana Province (Türkiye) were investigated using the skeletochronology method and the demographic structure was revealed. The mean age was 3.07 years in females and 2.93 years in males. Derived from the LAG configuration, the age at sexual maturity was 1 year in males and 2 years in females. There was no significant correlation between the SVL and age. Moreover, the mean age and SVL were not statistically different between sexes. Results obtained here indicate that C. chamaeleon is one of the short-living lizard species when compared to other lizards. © 2022, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi).

Samples were collected from fish farming cages in selected coordinates (Bodrum, Salihli Region, Turkey) on September, October 2011 and March, April 2012. Method: validation and analyses were carried out by HPLC method. For FF; LOD values were 25.11 ppb for sea water, 27.07 ppb for sediment as well as 38.16 and 37.95 ppb for Mullus barbatus and Oblada melanura fish samples. FFA value for Mullus barbatus was 39.60 ppb, respectively. For CAP in sediment samples, LOD values were found as 53.59 ppb. In 4 different sampling areas (A, B, C, D), the lowest temperature was recorded as 14 °C in March 2012 but the highest was 28.3 °C in October 2011; the lowest dissolved oxygen (mg/L) values were detected in March 2012 (from 6.05 to 6.44), the highest in October 2011 (10.78-11.55). The pH values slightly varied month by month; the lowest was 7.9 and the highest 8.6. This research revealed that dissolved oxygen and pH values of the collected seawater samples were in accordance with the normal limits of the offshore seawater values; no significant residue of the analyzed veterinary drugs was found to be present, and all values were found to be lower than LOD values in the sampled fish farms. In conclusion; there was no pollution caused by veterinary drugs. © by PSP.Öğe Investigation of intra-esophageal air kinetics and esophageal sphincters in patients with total laryngectomy during esophageal speech(Springer Verlag, 2015) Bozan A.; Vardar R.; Akyildiz S.; Kirazli T.; Ogut F.; Yildirim E.; Bor S.The purpose of this study was to evaluate the air kinetics of well- and poor-speaking patients and their upper (UES) and lower (LES) esophageal sphincter pressures. The esophageal speech capability of 23 total laryngectomy patients was assessed with the Wepman scale. LES and UES points and pressures were measured, and air kinetics were compared. All patients were male, with an average age of 58 years. Both the LES and UES pressures were not statistically different between good-speaking and poor-speaking patients (p > 0.05). The ability to speak was estimated only by looking at tracings. Good speakers are able to retain air successfully and on a long-term basis between the upper and lower esophageal sphincters. During short and/or rapid speech, these patients are able to rapidly suck and then expel the air from their upper esophagus. During long speeches, after sucking the air into their distal esophagus, they used the air in the upper part of the esophagus during the speech, only later seeming to fill the lower esophagus with the air as a possible reserve in the stomach. It has been shown that the basic requirement for speaking is the capacity to suck and store the air within the esophagus. For successful speech, the air should be stored inside the esophagus. MII technology contributes to our understanding of speech kinetics and occupies an important place in patient training as a biofeedback technique. © 2015, Springer-Verlag Berlin Heidelberg.Öğe Investigation of some veterinary drug residues in sea water, sediment, and wild fishes captured around fish farms in the Aegean Sea: Oxytetracyline, ivermectin and emamectin [Ege Denizinde balık çiftlikleri etrafında avlanan doğal ortam balıkları ile çevredeki su ve sedimentin bazı veteriner ilaç kalıntıları yönünden incelenmesi: Oksitetrasiklin, ivermektin ve emamektin](Chartered Inst. of Building Services Engineers, 2015) Baydan E.; Kaya S.; Çağirgan H.; Yildirim E.; Altintaş L.; Yurdakök B.; Ekİcİ H.; Aydin F.G.; Küçükosmanoğlu A.G.Veterinary drug residues and their metabolites in food are regularly investigated by local authorities; however their fate in the environment is still unknown. Despite the importance of the aquaculture industry and the widespread use of antibiotics; limited scientific information regarding their residue in natural fish, sediment and sea water are available in TURKEY. The current study; which is the first study in this area, was undertaken to determine the oxytetracycline (OTC), ivermectin (IVM) and emamectin benzoate (EMA) residues from samples of wild fishes (Oblada melanura, Mullus barbatus), sea water and sediment collected in four different months, caught around the fish cages near Salihli Island in Bodrum, Aegean Sea. Samples were analyzed by High Pressure Liquid Chromatography (HPLC) followed by the validation for each matrix. No residues were found to be above the Limit of detection (LOD) levels of the validated methods in the screened samples. In order to understand the possible risk of veterinary antibiotics, especially for low dose accumulation, to the ecosystem for sustainable aquaculture, conduction of more screening analysis with expanded possible matrices would be beneficial. © 2015 Chartered Inst. of Building Services Engineers.

The few clinical studies which have been conducted on HPA-axis function in burnout have produced inconsistent results. The etiological relationship between sBDNF and burnout has not yet been studied. The aim of the current study was to investigate the role of BDNF and HPA axis in the neurobiology of burnout. In the current study 37 clinically diagnosed burnout participants were compared with 35 healthy controls in terms of BDNF, HPA axis, burnout symptoms, depression, anxiety and psychosomatic complaints. Basal serum cortisol, sBDNF and cortisol level after 1 mg DST was sampled. We found no significant differences in terms of HPA-axis function (for basal serum cortisol, p = 0.592; for cortisol level after 1 mg DST, p = 0.921), but we did find lowered sBDNF levels in burnout group (88.66 ± 18.15 pg/ml) as compared to healthy controls (102.18 ± 20.92 pg/ml) and the difference was statistically significant (p = 0.005). Logistic Regression Analysis revealed that emotional exhaustion (p = 0.05), depersonalization (p = 0.005) and depression (p = 0.025) were significantly associated with burnout. sBDNF levels correlated negatively with emotional exhaustion (r = -,268, p = 0.026), depersonalization (r = -,333, p = 0.005) and correlated positively with competence (r = 0.293, p = 0.015) sub-scales of burnout inventory. However, there were no significant relationships between cortisol levels and sBDNF levels (r = 0.80, p = 0.51), depression, anxiety, psychosomatic complaints and burnout inventory. Our results suggest that low BDNF might contribute to the neurobiology of burnout syndrome and it seems to be associated with burnout symptoms including altered mood and cognitive functions. © 2008 Elsevier Inc.

This signal, which is due to erenkov light production at the PMT window, could interfere with the calorimeter signal and mislead the measurements. In order to find a viable solution to this problem, the response of four different types of PMTs to muons traversing their windows at different orientations is measured at the H2 beam-line at CERN. Certain kinds of PMTs with thinner windows show significantly lower response to direct muon incidence. For the four anode PMT, a simple and powerful algorithm to identify such events and recover the PMT signal using the signals of the quadrants without window hits is also presented. For the measurement of PMT responses to erenkov light, the Hadron Forward calorimeter signal was mimicked by two different setups in electron beams and the PMT performances were compared with each other. Superior performance of particular PMTs was observed. © 2010 IOP Publishing Ltd and SISSA.
