Ural, Mesut; Yildirim, Numan; Danabas, Durali; Kaplan, Olcay; Yildirim, Nuran Cikcikoglu; Ozcelik, Mehtap; Kurekci, Eylem Funda
Concentrations of metals were determined in the gills, liver, kidney, heart and muscle in Capoeta umbla caught from six stations from the Munzur River system. Metal concentrations in the tissues tended to vary significantly among stations (p < 0.05). Liver (Cu, 10.10 +/- A 0.23-23.03 +/- A 9.37 ppm; Zn, 14.67 +/- A 3.01-21.82 +/- A 2.39 ppm; Cd, 18.04 +/- A 4.56-52.69 +/- A 10.65 ppb and Fe, 28.87 +/- A 6.78-115.11 +/- A 34.87 ppm) and kidney (Cu, 1.80 +/- A 0.25-3.70 +/- A 0.62 ppm; Zn, 20.81 +/- A 0.37-29.36 +/- A 0.70 ppm; Cd, 132.06 +/- A 5.29-639.51 +/- A 20.14 ppb and Fe, 24.40 +/- A 1.98-59.39 +/- A 1.97 ppm) tissues showed higher metal concentrations than other tissues. It seems that metal contamination in the river is too high for the health of fish and the people who eat them. The geographical locations of catch, season, nature of diet, and the size of fish used for analyses might lead to different metal concentration in the same fish species.

Yildirim, Nuran Cikcikoglu; Turkoglu, Semra; Yildirim, Numan; Ince, Olcay Kaplan
Antioxidants are our first line of defense against free radical damage, and are critical for maintaining health. The need for antioxidants becomes even more critical with increased exposure to free radicals. In the past few years there has been an increasing interest in determining relevant dietary sources of antioxidant phenolics. Mushrooms have been not only used as food materials with their unique flavor and texture, but also recognized as an important source of biologically active compound of medicinal value. In our study, to determine the antioxidant properties of the methanolic extracts of Pleurotus eryngii strains collected from different region of Tunceli, radical scavenging activity, total phenolic contents, reducing power, metal chelating activity and total antioxidant status (TAS) were analyzed. The analysis of phenolic compounds was performed by HPLC. In particular, the methanolic extract of P. eryngii collected from city center revealed the highest DPPH radical scavenging activity and reducing power, while the highest total phenolics and total antioxidant status was determined in P. eryngii collected from Pulumur. P. eryngii collected from Ovacik showed the highest chelating effects. Concentration of phenolic compounds found in three wild edible mushrooms. Kaempferol and catechin were not determined in musrooms species. The highest rutin levels were determined in ovacik. Resveratrol was determined only in Pulumur. The studied wild mushrooms might be beneficial to protect human body against oxidative damage.

Cimen, M.
The influence of separation from dam on suckling behavior of lambs was tested from day 5 after lambing until the lambs were 8 days old. The twelve ewes with their lambs were randomly assigned in equal numbers to two treatments; separating from dam (S) and non-separating without suckling (NS). Separation from dam resulted in lower duration and higher frequency of suckling. The lambs in S treatment had shown lower milk intake as compared to rearing lambs by NS treatment until 8th day. Milk intake, duration and frequency of suckling in both groups decreased as age of the lamb increased until last day. Separation treatment was associated with stress in dams and their lambs had negative effect on suckling behavior and milk intake of offspring.

Banu, Kutlu
Phytoplankton growth and microzooplankton grazing were investigated at one station in the Homa Lagoon from February to January in 2006-2007. Our results showed significant seasonal variations in phytoplankton dynamics. Microzooplankton was mainly composed of dinoflagellates and tintinnid ciliates and nauplii. Microzooplankton grazing increased with increasing of temperature. Grazing rate was maximum levels in spring and summer. Microphytoplankton, which dominated the total algal biomass and production, were characterized by the proliferation of several chain-forming diatoms. Small heterotrophic flagellates and aloricate ciliates were the main controllers of phytoplankton. Phytoplankton represented a significant for micrograzers, which grazing represented 20-120% of diatom and cynabacteria algal production during 2006-2007. Microzooplankton has, however, a relatively high impact on microphytoplankton, as > 45% of microalgal production was consumed throughout the year. These results suggest that the low grazing was one of the factors contributing to the development of the spring bloom. All of seasonal bases, the phytoplankton production were grazed by microzooplankton in summer, autumn and winter-spring seasons have been changing between 20%-120%. The seasonal variation in the microzooplankton grazing pressure seems to result from the dominant size class of the phytoplankton community of this lagoon diatom and cynabacteria.

Danabas, Durali; Ural, Mesut
The aim of this study was to evaluate Copper (Cu), Zinc (Zn), Selenium (Se), Chromium (Cr) and Cadmium (Cd) concentrations in liver, muscle, gills and kidney tissues of Capoeta trutta collected from four sites of Keban Dam Lake, Turkey. The highest heavy metal level in all tissues was for Zn, while Cd was the lowest. The lowest heavy metal levels were generally found at Station 4 (Agin) for all tissues (p < 0.05). There were statistically significant differences among stations for Cu, Zn, Cr and Se in gills; for Cu, Zn, Se and Cr in liver and kidney; and Cu, Zn and Cr in muscle (p < 0.05). Cadmium concentrations did not differ between sites for any of the tissues. Turkish Food Codex sets the maximum limits of Zn, Cu and Cd as, 50, 20 and 0.05 mg kg(-1) dry weight, respectively, in the muscle of fish used for human consumption. In our study, the level of Zn was higher than Turkish permissible limits only at Station 3 (Guluskur). Cadmium levels were much higher than permissible limits at three stations [S1 (Pertek), S2 (Kockale) and S3], whereas Cu levels were within permissible limits in all stations.

Altinterim, Basar; Gulec, Azime Kucukgul; Aksu, Onder
In this study, the safety dose of Eucalyptus camaldulensis hydrosol on carp (Cyprinus carpio) was investigated. Powdered eucalyptus leaves were mixed with deionized water and then distilled. The hydrosol was added into aquariums at doses of 0.05, 0.10 and 0.15 ml L-1 Temperature, pH, hardness and dissolved oxygen level of the water were recorded before and after hydrosol adding. The control and test experiments were repeated three times. Data obtained from the safety dose tests of E. camaldulensis hydrosol were evaluated using the Probit Analysis Statistical Method. The 5-h LC50 value (95 % confidence limit) of the safe dose of E. camaldulensis hydrosol was estimated to be 0.93 ml L-1(0.03-0.11). It can be seen that 0.05 ml L-1 doses of eucalyptus hydrosol do not create any kind of mental disorder. In the fish exposed to 0.10 and 0.15 ml L-1 doses, some mental disorders (rolling, numbness) and, at the end of 5 h, mortality in all the trial fish have been determined. The number of dead fish was significantly exposed to E. camaldulensis hydrosol (P<0.05).

Harlioglu, Muzaffer Mustafa; Kutluyer, Fitiz; Gür, Seyfettin
In the present study, the sperm number of wild caught Astacus leptodactylus was counted in the beginning of reproduction season. In addition, the reproductive system, testes, and vasa deferentia were weighed, and gonado-somatic index and testicular index were calculated. Twenty-five adult males of A. leptodactylus were used for the study. Significant linear regressions were found between body length (and weight) and sperm count, reproductive system weight, testes weight and vasa deferentia weight (P < 0.05). The mean sperm number of vas deferens for the size range of 41-56 mm carapace length crayfish was 5.72 +/- 4.54 x 10(9) sperm/distal vas deferens (DVD) section. Sperm number ranged from 4 x 10(8) to 8.5 x 10(9) sperm/DVD section. The results revealed that an increase in body weight causes an increase in sperm number. For example, mean sperm number was 3.87 +/- 2.87 x 10(9) for the weight range of 15-24 g crayfish, 5.01 +/- 2.62 x 10(9) for the weight range of 25-35 g crayfish and 7.37 +/- 2.87 x 10(9) for the weight range of 36-42 g crayfish. In conclusion, this study provides some data on the male reproduction characters and needs to be improved with details about the reproductive performance of males (i.e., sperm number and quality) in order to reach a maximum reproductive efficiency in captivity.

Güleç, Azime Kucukgul; Cengizler, Ibrahim
Tilapia (Oreochromis niloticus Linnaeus, 1758) were infected with Streptococcus iniae (Cat No: ATCC 29178) and the plasma changes in the acute phase protein (APP) members were examined at different time periods. A total of 72 fish with average body weights of 60 g were used. Fish in the infected group (group I) were intraperitoneally injected with S. iniae at 3.3 x 10(5) colony forming unit (CFU) in 0.1 mL level to the fish. The other group (group II) was subjected to handling stress near the infection. The control group was constituted by providing optimum conditions. On days 7, 14, and 21, blood samples were taken from the caudal veins of the fish under the appropriate anesthesia. The samples were examined on the basis of APPs, C-reactive protein (CRP), fibrinogen (FB), serum amyloid A (SAA), and transferrin (TF) and the changes in the plasma values were recorded. The internal and external symptoms seen during the examinations were detected as follows: the color concentration in 1-2 days in the infected groups, irregularity and retardation in the movements of the fish, hyperemic spots on the skin, and bloody effusion in the internal organs. In both of the infected groups, the CRP and SAA plasma values increased on days 7, 14, and 21 (P < 0.05). Remission was observed in the plasma TF levels in the first week; however, aft er the second week the levels reached normal values. Decreases in the FB levels of all of the samples were detected. Based on the data acquired in this study, it was concluded that changes in the plasma levels of the APP members can be used as a significant bioindicator in the pathogenesis of the disease in fish infections.

The compensatory growth response of the European sea bass (Dicentrarchus labrax) that faced cycling starvation and restricted ration was assessed. Juveniles (10.5g) were stocked into 15 tanks at a density of 25 fish per tank. Five different feeding regimes were tested on triplicate groups of fish: CSatiation: control fed for 60days without deprivation, CRestricted: 25% restricted feeding, S-R: 1day starvation then 4days CRestricted feeding, R-F: 1day CRestricted feeding then 4days CSatiation feeding, and, finally, S-F: 1day starvation then 4days CSatiation feeding. The specific growth rate of fish in the CSatiation (2.5 +/- 0.06%day-1), S-F (2.5 +/- 0.11%day-1) and R-F (2.4 +/- 0.18%day-1) were significantly higher than that of CRestricted (2.2 +/- 0.05%day-1) or S-R (2.0 +/- 0.01%day-1). Fish in S-F group were able to achieve catching up with the CSatiation. There was no significant difference in feed conversion rates but R-F and S-F consumed approximately 34% more feed than CSatiation following the first re-feeding day. Although, the highest lipid content was observed in CSatiation (14.4%), S-R (33.3% dry matter) had the highest water content compared with the CSatiation and CRestricted (37.8% and 36.9% dry matter respectively). In conclusion, it may be concluded that sea bass has rapid response to cycling starvation/re-feeding and that a 25% restricted feeding ratio is insufficient to invoke a compensatory growth response in sea bass.

In this study, paleontological and biostratigraphic characteristics of the Paleogene geologic units outcropping between Kuscu and Macun villages located around Temelli district, Polatli, Ankara. We have examined the patterns of Pelecypoda and Gastropoda samples. Seven measured stratigraphic section from the west of Macun village to east of Kuscu village, which contains the Pelecypoda and Gastropoda patterns, reach total thickness of 52 metres. As a result of field studies, seven species belongs to class of Pelecypoda and one of the new sixteen species belongs to class of Gastropoda have been described. Considering paleogeographic distribution and biostratigraphy of described fauna, it is quite proper to propose that they represent Thanetian age and can be interpreted as belonging to Kirkkavak Formation. Furthermore, the paleoecologic characteristics of the fauna strongly suggests that the shallow and temperate coastal marine facial conditions were prevalent at the region during that time span.

Emiroglu, Oya Nuran; Karatay, Gulnaz
Introduction: Falls in the elderly are a significant problem with consequences that may lead to death. Although many studies have been conducted regarding falls in the elderly, little is known of their own perceptions and experiences of falling. The purpose of this study was to better understand how the elderly living in institutions understand and perceive their experiences of falling. Materials and Method: A qualitative design was used based upon van Manen's phenomenological approach. Interviews were conducted with 22 elderly using a purposive sampling method. Van Manen's data analysis approach was used to analyze the data derived from the interviews. Results: Outcomes of this study showed that there were three main perceptions about falls for the elderly: Participants acknowledged falling as a painful experience and that falls should be expected in old age. Still others understood that life goes on but with new areas of concern which will require their attention and care. Conclusion: The results of this study show that all health care personnel, particularly the nurses who care for the elderly in an institutional environment, need to adopt an individualized and empathetic approach to those in their care. Falls happen often and can be fatal to the elderly. Thus it is very important for all health care professionals working with the elderly to be fully informed and involved in ensuring that their patients practice safe behaviors to guard against falls. Care should also be taken to ensure that their living environment is safe and secure.

The purpose of this study was to test the effects of a multistimulant home-based program on cognitive function among older adults. This study was conducted in northeastern Turkey between March and June 2010. It was planned as an experimental versus control two-group design and carried out on 96 (intervention group = 48, control group = 48) participants. The intervention and control groups were similar regarding sex, education, partner status, and continuous drug use. Data were collected with a Standardized Mini Mental Test, the Geriatric Depression Scale (GDS), and the Beck Anxiety Scale. Each senior received a total of 10 home visits on a once-per-week basis. Results for the intervention group showed that the Mini Mental State Test scores of the participants had statistically increased, and the Beck Anxiety and the GDS scores showed a decrease. The study found an association between the multistimulant home-based intervention program and cognitive function.

The risk of fish pathogen transmission via eggs can be reduced by disinfection in ozonated seawater. The aim of this study was to determine the suitable conditions for ozone disinfection of the eggs of gilthead seabream Sparus aurata, sea bass Dicentrarchus labrax, red porgy Pagrus pagrus, and common dentex Dentex dentex. The eggs were disinfected with a concentration (C) of 0.5 mg of ozone/L of water at four different exposure times (T = 2, 4, 8, and 16 min). The hatching rate was determined in triplicate for each treatment. Bacterial colonies were counted on tryptic soy agar and thiosulfate-citrate-bile salts-sucrose agar. At the end of the experiment, bacterial load and hatching rate were assessed together to determine the optimal ozone treatment values, which were estimated in CT units (i.e., C [= 0.5 mg/L] x T [min]). Optimal values were CT 2-4 (T = 4-8 min; 18 degrees C) for gilthead seabream and red porgy, CT 2 (T = 4 min; 18 degrees C) for common dentex, and CT 4 (T = 8 min; 15 degrees C) for sea bass.
