Item Changes in the glutathione-s transferase activity of the mussel Mytilus galloprovincialis during exposure to bisphenol-A(Parlar Scientific Publications, 2014) Arslan O.C.; Parlak H.; Boyacioglu M.; Karaslan M.A.; Katalay S.Bisphenol A (BPA), is one of the most important industrial chemicals synthesized for diverse applications. The environmental concentrations of BPA are at high risk level due to use widely in many fields of industry according to the latest studies. In our study mussels (Mytilus galloprovincialis) were exposed to 50 μg/L of BPA and the changes of hepatic biomarker glutathione-s transferase (GST) activity were investigated. The results showed that the activity of GST was increased in BPA group (20.44 %) compared with control. Based on this experiment, we recommended that GST might be used as a biomarker of environmental pollution. © by PSP.Item Quality parameters of vineyard irrigation water in a semi-arid region: The Plain of Alasehir, Turkey(Parlar Scientific Publications, 2014) Yagmur B.; Aydin S.; Okur B.; Coban H.; Simsek H.Production of seedless raisins is extremely important in Aegean Region in Turkey. The Plain of Alasehir in province of Manisa in Aegean Region is extremely important for seedless raisin production since 25% of the seedless raisin has been grown in this area. The irrigation water samples were collected from 13 different water distribution locations in the Plain of Alasehir. Results showed that pH and EC (electrical conductivity) values were in a reasonable range except EC levels from two locations were slightly high. The vineyard irrigation water in the region was classified as type of C3S1. It was suggested that, the salt content might be monitored continuously since salinity might increase in the soil through the end of the irrigation season. The most common cations were Ca++ and Mg++, and anion was HCO3\ Trace elements and heavy metals were under the risk limits except Mn was high in three locations. Boron was high in nine sampling locations. Overall, irrigation waters in the Plain of Alasehir were suitable for vineyard irrigation as long as the contents of boron and salinity were continuously monitored. © by PSP.Item Dinoflagellate cyst assemblages in surface sediments from Homa Lagoon (Izmir Bay, eastern Aegean Sea, the Mediterranean)(Parlar Scientific Publications, 2014) Aydin H.; Yürür E.E.; Uzar S.The occurrence and abundance of dinoflagellate cysts was investigated for the first time in Homa Lagoon, one of the most important lagoons of Aegean Coast of Turkey. Twelve cyst morphotypes were identified and cyst abundance was ranged between 15 and 71 cyst g-1 dry weight sediment in the study area. Dinoflagellate cyst assemblages were mainly dominated by cyst of Alexandrium minutum, Spiniferites delicatus, Spiniferites bulloideus. Sediment types were mainly clay and silty sand. Dinoflagellate cysts were particularly distributed in the clay and silty sediment. © by PSP.Item Dinoflagellate cyst assemblages in surface sediments of southwestern black sea and Çanakkale strait (dardanelles)(Parlar Scientific Publications, 2015) Aydin H.; Balci M.; Uzar S.; Balkis N.In order to document the distribution of dinoflagellate cyst assemblages, eight surface sediment samples were collected in surface sediments from southwestern Black Sea and Çanakkale Strait. A total of 25 cyst types and 1 unknown cyst type were identified. Samples displays low total cyst concentrations with values ranging from 8 to 346 cyst g-1 dry weight sediment. Autotrophic dinoflagellates highly and significantly contributes (p<0.01) to the total cyst concentration. Lingulodinium machaerophorum, cyst type of Al-exandrium minutum and Spiniferites bulloideus were dominant at the sampling points. Higher cyst concentration and diversity observed at stations in Black Sea could be linked to the type of sediment. Small-sized sediment (sand-silt) were mostly dominant at the Black Sea stations compare to the more sandy type sediment of Çanakkale Strait. Present study provides the first modern dinoflagellate cyst records from surface sediments of southwestern Black Sea and Çanakkale Strait. © by PSP.Item The nutritional conditions and some heavy metal contents of the vineyards in a semi-arid area(Parlar Scientific Publications, 2015) Aydin S.; Yagmur B.; Coban H.; Simsek H.Turkey is one of the most important seedless raisin producers in the world market. Approximately, 82% of the seedless raisin has been produced in the western part of Turkey since the climate (semi-arid) of this region is very appropriate to grow seedless grape. More specifically, the Plain of Alasehir, located in the Gediz Basin in Aegean Region has been known its high quality seedless raisin production. About 25% of the seedless raisin of the entire Aegean Region is produced in the Plain of Alasehir. Therefore, the Plain of Alasehir region was selected to determine some heavy metal contents (Cd, Co, Cr, and Pb) and certain macro and micro element contents (N, P, K, Ca, Mg, Fe, Zn, Mn, and Cu) of the leaf samples obtained from the vineyards in the area. The plant samples from 13 vineyards were analyzed by collecting the samples across the first plant bunch during the veraison period. In terms of nutrition profile, N deficiency was detected in 15% of vineyards while P deficiency was determined in 38.5 % of the vineyards. Similarly, Fe deficiency was detected in the 30.8 % of the vineyards. The contents of Zn, Mn, Cu, K, Ca, and Mg were sufficient in all of the vineyards. Some heavy metal contents of the leaf samples were analyzed and it was found that there was no pollution for the Cd, Co, and Pb in all the vineyards. Cr pollution was not detected in 93.2% of the samples.Item Seasonal investigation of the protein, carbohydrate and lipid contens of dominant macroalgae on the western coast of the black sea(Parlar Scientific Publications, 2017) Yesilova K.; Balkis N.; Taskin E.In this study, the ecological features and total protein, carbohydrate and lipid amounts of the dominant macroalgal species of the western Black Sea coast were investigated. Seasonal samplings were carried out at five coastal stations (Sts. İğneada, Kiyiköy, Yaliköy, Karaburun, Kilyos) between November 2012 and August 2013. After the examination of the collected samples, 25 macroalgal species belonging to 9 families and 11 genera were determined. The highest protein content has been determined in the summer season sampling of Callithamnion corymbosum with a percentage of 47.09% (St. igneada), while the lowest one has been determined in the winter season sampling of Corallina officinalis with a percentage of 0.10% (St. Yalikoy). The highest proportion in carbohydrate content was observed in Ceramium virgatum (87.02%) collected in summer at Kilyos station, while the lowest one has been found in Cystoseira barbata (2.60%) which was sampled in the autumn season at Karaburun station. The highest lipid ratio has been found in summer in Callithamnion corymbosum (22.04%, St. Igneada), and the lowest ratio has been found in spring in Ulva compressa (0.75%, St. Kilyos). The sea temperature values varied between 6.71°C-25.02°C, the salinity varied between 11.95-16.54%o, the dissolved oxygen varied between 6.95-14.61mg/L and the pH values varied between 4.67-7.28 during the study. © 2017 Parlar Scientific Publications.

Since the larval control of the sand flies is very difficult and almost impossible, the fighting has mainly been carried out for the adults. In this research the fumigant toxicity of two plant essential oils obtained from Satureja cuneifolia Ten. and Ziziphora clinopodioides Lam. was evaluated against fieldcollected adult Phlebotomus sand flies under laboratory conditions. The fumigant activity was tested by exposing the sand flies to essential oil vapors at 10, 20, 50 and 100 μL/L air concentrations. Knock time 50 (KT50) values and the 95% confidence limits were calculated by using a probit analysis program. A decrease in the KT50 value is observed in S. cuneifolia and Z. clinopodioides essential oils in a concentration dependent manner. KT50 values at the highest concentration (100 μL/L air) are 9,3 and 11,6 min, respectively. After a 1 h exposure period, both test oils produced 100% mortality at all the concentrations tested. The results of the research suggest that essential oils from these two plants have a potential as control agents for sand flies. © by PSP.Item Anti-acetylcholinesterase, antiprotozoal and cytotoxic activities of some Turkish marine algae(Parlar Scientific Publications, 2019) Cinar E.; Taskin E.; Tasdemir D.; Ozkale E.; Grienke U.; Firsova D.The crude (MeOH:CHCl3) and n-hexane-soluble extracts from four brown algae (Phaeophyceae) [Petalonia fascia, Cystoseira crinita, Cystoseira foeniculacea, and Halopteris scoparia], one red alga (Rhodophyta) [Jania rubens] and three green algae (Chlorophyta) [Chaetomorpha aerea, Codium fragile subsp. fragile, and Ulva compressa] from Turkish coasts (Izmir Bay, Ayvalik and Çanakkale) were assessed in vitro for their acetylcholinesterase (AChE) inhibitory activities at 200, 150, 50, 20 μg/mL test concentration with Ellman's method. The crude extract of P. fascia possessed the highest inhibition (IC5 0 value of 19,22±10,47 μg/mL) against AChE. Galanthamine HBr was used as standard drug that gave against AChE enzyme IC5 0 of 3.44±1.14 μM. In the second stage, the crude, hexane-soluble, chloroform-soluble and water-methanol soluble extracts of the marine algae were observed in vitro against parasitic protozoa (Plasmodium falciparum, Trypanosoma brucei brucei, Trypanosoma cruzi ve Leishmania infantum). According to results, the most potent protozoal activities were shown by the Khex of C. crinita (IC5 0 value of 10,62 μg/ml), followed by the Khex of C. fragile subsp. fragile (IC50 value of 11,89 μg/ml). The hekzan-soluble (Khex) and chloroform-soluble (KCH) extracts gave the best results. The marine algae were also tested on MRC-5 cells (human fibroblasts) for by controlling tamoxifen. The extracts of H. scoparia, C. aerea ve C. fragile subsp. fragile showed toxicity. © by PSPItem Particle size affects physical properties and antioxidant activity of unripe banana peel(Parlar Scientific Publications, 2020) Savlak N.; Turker B.Unripe banana peel flour of Dwarf Cavendish banana (Musa spp. AAA) peel (Gazipasa, Turkey) of different particle sizes (<212 μ m, 212-315 μm, 316-500 μm, 501-700 μm) were investigated for their physicochemical, functional properties and antioxidant activity and data were analyzed by SAS Statistical Programme using Completely Randomized Design Proc Glm prosedure. Particle size mostly affected L* value (60.60 - 65.03), bulk density (71.87 - 74.78 kg m"3), tapped density (294.25 - 357.29 kg m~3), wettability (1.19 - 9.72 s), antioxidant activity (159.86 - 198.57 mmol Fe (II) / g dry peel flour; 40.11 - 44.79 mg Trolox equivalent / g dry peel flour) and phenolic content (2.17- 2.64 mg GAE / g dry peel flour) of unripe banana peel flour. L* value, tapped density and wettability decreased; bulk density, water absorbtion index and oil holding capacity increased as particle size increased. Antioxidant activity (FRAP and DPPH methods) and total phenolic content of unripe banana peel flour also increased by increasing particle size. This study is the first study mentioning the effect of particle size on quality of unripe banana peel. To the best of authors' knowledge, the study also provided the first data on some handling properties of unripe banana peel flour in terms of tapped density, Hausner ratio, Carr Index and wettability. © 2020 Parlar Scientific Publications.

Pathogens were surface inoculated on frankfurters ca. 5±1 log cfu/g and the inoculated frankfurters were stored at 4°C for 75 days. Microbiological analysis and pH measurements were conducted at days 0, 15, 30, 45, 60 and 75 of cold storage. In the first part of the study, different brands of commercially available frankfurters produced from cattle meat (Brand A, B, C, D, E) were investigated in order to evaluate which brand aided pathogen survival in acidic environment. Pathogen resistance to synthetic gastric fluid (SGF) was very weak in brands A, B, C, and D samples, and survivor counts were undetectable during SGF experiments after "Day 0" of the storage. These preliminary experiments showed that pathogens had stronger acid resistance on one brand of frankfurters, therefore in the second part of the study triplicate trials were conducted with this brand (Brand E). On brand E frankfurters, the pathogens were still detectable at the 45th day of storage after SGF exposure except for 0157:H7. The gradual decrease in the pH of this brand of frankfurters might have aided acid resistance of the pathogens. Results show that in every brand of samples tested, the non-0157 serogroups had higher survivor counts than 0157:H7, during storage and SGF experiments of frankfurters. © 2021 Parlar Scientific Publications.
