Kutlu, Banu; Aydın, Rahmi; Danabas, Durali; Serdar, Osman
Seasonal variations in species composition and growth dynamics of phytoplankton in Uzuncayir Dam Lake (Tunceli, Turkey) were studied in relation to ecological factors by collecting horizontal water and phytoplankton samples for over a year. A total of 46 phytoplankton taxa were recorded, where Bacillariophyta was the most abundant in species number representing 24 taxa. Diatoms were the most conspicuous phytoplankton in terms of abundance as well as occurrence frequency. Charophyta, Chlorophyta, Cyanobacteria, Ochrophyta, Miozoa, and Euglenozoa were the least abundant. However, some Diatoms (Gyrosigma attenuatum, Hippodonta hungarica, Meridion circulare, Nitzschia clausii, Nitzschia frustulum, Pantocsekiella ocellata, Rhoicosphenia abbreviata), Charophytes (Cosmarium granatum, Mougeotiopsis calospora), Cyanobacteria (Leiblenia epiphytica, Planktothrix agardhii); Dinoflagellates (Ceratium hirundinella, Parvodinium africanum, Parvodinium inconspicuum, Peridinium cinctum), and Ochrophyta (Dinobryon pediforme) were also noticeable, with their occurrence in all seasons. Canonical correspondence analysis (CCA) and principal component analysis (PCA) were employed to analyze the relationship between occurrence and abundance of phytoplankton species as well as the ecological factors. The results showed that pH and the concentrations of NH4, NO3, and PO4 influenced seasonal occurrence and abundance of phytoplankton species in the lake. Uzuncayir Dam Lake may be classified as an oligotrophic lake with the mean value of nitrate 2.62 mg L−1 and phosphate 0.23 mg L−1 as supported by the occurrence of various phytoplankton groups. Findings related to pollution indices yielded that Uzuncayir Dam Lake is on the edge of the moderate state of organic pollution.

In the study, Zn in the size of 40–60 nm and 80–100 nm and ZnO in the size of 10–30 nm were applied to A. salina and D. magna individuals in 7 groups with 3 repetitions. Measurements were made at 24th, 48th and 72nd hours and elimination values were examined at +24 h. LC50 values of NPs were determined and chemical analysis (metal accumulation and elimination), ion quantities which were given to the environment and the survival rates of organisms were determined after the exposure. According to the results of phase contrast microscopy, it was found that both experimental organisms absorbed the NPs in the medium level. In the toxicity results of D. magna, it can be said that Zn NP (40–60 nm) has a highly toxic effect only at 50 ppm concentration for 48 h and lethal dose can be accepted as of 5 ppm at the end of 72 h. In A. salina individuals, it is clearly seen that there is an increase in mortality in organisms parallel to the dose increase. Although all NPs were applied to organisms in low doses corresponding to environmental values, it was observed that toxic effect was in parallel with the increase in time. It is clearly known that there is the inverse proportion between the size of NPs and the toxic effect. The smaller the size of NPs is, the higher the toxic effect becomes When the results of Zn accumulation and elimination of A. salina and D. magna individuals exposed to the Zn and ZnO NPs were examined; it was found that accumulation and elimination occurred in parallel with the increase in concentration at each application hour and elimination. Intensive and possible misuse of nanoscale materials is one of the biggest threats to the environment and all living things worldwide.

Yersinia ruckeri is the causal agent of enteric redmouth (ERM) in trout. This study aimed to investigate the effectiveness of nontoxic ozone on Y. ruckeri-infected trout cells in in vitro conditions. Rainbow trout macrophages (RTS-11) were exposed to Y. ruckeri for 24 h after being incubated with the ozonized medium at nontoxic concentration. Effective concentrations of nontoxic ozone (3 gamma) and bacteria (1.5 x 108 cfu/mL) were determined by viability tests. The expression of caspases 1, 3, 8, and 12 was determined by real-time PCR and protein levels investigated by ELISA method. Apoptotic-necrotic cell ratios were determined by acridine orange and ethidium bromide staining. Bacterial stimulations of caspases (1, 3, 8, and 12) were suppressed by ozone mostly at the translational level. While bacterial infection increased the count of apoptotic and necrotic cells at different stages, ozone significantly reduced this condition. Obtained data indicate possible use of nontoxic ozone as a safe and effective treatment alternative for increasing host defenses and eliminating the infection in the case of yersiniosis in fish.

Nanopartikül (NP) içeren ürünler; tıbbi cihazlar, elektronik, enerji üretimi ve depolanması, sağlık bilimleri ve gıda sektörleri gibi birçok alanda kullanılmaktadır. NP?lerin büyüleyen özelliklerine rağmen, insan ve çevre sağlığına etkileri konusunda çok az şey bilinmektedir. Çünkü nanomateryaller metallerden, metal oksitlerlerden ve yarı-iletken maddelere kadar geniş bir yelpazeye sahiptir. Sucul sistemler ve besin zincirini oluşturan organizmalar antropojenik faaliyetlerden salınan NP?lerin etkileri sebebiyle risk altındadırlar. Bu çalışmada, tatlısu ve deniz suyu ortamında yaşayan birincil üretici fitoplankton türlerinden Selenastrum capricornutum ve Nannochloropsis oculata ile birincil tüketici zooplankton türlerinden Daphnia magna ve Artemia salina metal ve metal oksit NP?lere maruz bırakılarak nanotoksisite testleri gerçekleştirilmiştir. Çalışmada kullanılan metal ve metal oksit NP?leri (Al, Al2O3, Cu; CuO, Fe2O3, Zn ve ZnO) ile laboratuvarda sentezlenen Ag-NP?leri, CdSe ve PbSe kuantum noktacıklarının karakterizasyonu TEM, DLS, Zeta Potansiyeli, XRD, SEM, FT-IR ve UV görünüm spektroskopisi yöntemleriyle gerçekleştirilmiştir. Organizmalarda NP?lere bağlı birikim ve eliminasyon oranın belirlenmesi ICP-MS analiziyle yapılmıştır. Fitoplankton ve zooplanktonlarda NP etkileri faz kontrast mikroskobuyla görüntülenmiştir. Akut toksisite etkileri 24, 48 ve 72 saatlik periyotlar boyunca fitoplankton populasyonunun büyümesi flurometreyle in-vivo chl-a incelenmiştir. Zooplanktonlardaki toksik etkiler, mortalite ve oksidatif stres belirteçlerinden glutatyon (GSH) ve tiyobarbitürat reaktif maddeler (TBARS) testleriyle incelenmiştir. Sonuçlar NP?lerin organizmalar üzerindeki farklı etkilerini göstermekle birlikte, NP?lerin birikim ve eliminasyon oranlarında farklılıklar olduğunu göstermiştir. Organizmadaki birikim NP konsantrasyonuyla artış göstermiştir. NP?lerin metal iyon salınımları, tatlısu ve deniz suyu ortamında farklı olmakla birlikte, herbir NP?ün farklı iyon salınımı gösterdiği gözlenmiştir. NP?lere maruz bırakılan fitoplanktonların yüzeyleri NP?ler ile sarıldığı gözlemlenmiştir. Benzer sonuçlar zooplanktonlarda da gözlemlenmiştir. Oksidatif stres analizlerinde, TBARS değeri D. magna bireylerinde artış gösterirken bazı NP?ler A. salina?da azalmasına neden olmuştur. Benzer şekilde GSH seviyesinde azalma ve artmalar meydana gelmiştir. Organizma tarafından alınan NP?ler bir üst tüketici için tehlike oluşturmaktadır. Ayrıca fitoplanktonların yüzeylerinin NP?lerle kaplanması, üst besin zincirini oluşturan tüm organizmalar için risk oluşturmaktadır

Yersiniosis is a systemic disease caused by Yersinia ruckeri, which is particularly affecting Enteric red mite (ERM) disease in trout. There are still many issues regarding the mechanism of apoptosis and necrosis that play a role in the pathogen-host relationship in the disease. In the project, it was aimed to maintain the life of the cells and killing the bacteria by providing anti-apoptotic and anti-necrotic effect via application of therapeutic concentration of ozone to the macrophages infected with Y. ruckeri. In this study, the cells of the rainbow trout-originated cell line (RTS-11, mononuclear / macrophage) were exposed to the appropriate number of bacteria (Yersinia ruckeri, ATCC- 29473, serotype 1) for 24 hours after being incubated with ozonized medium (30 min) at the nontoxic concentration. For this purpose, effective concentrations of nontoxic ozone and bacteria were demonstrated by viability tests (3 Gamma, 1.5x108, respectively). After incubation times, the expression levels of caspases 1,3,8 and 12 were determined by realtime polymerase chain reaction and protein levels were investigated by ELISA method from the obtained lysates. In addition, apoptotic-necrotic cell ratios were determined in acridine orange and ethidium bromide staining in experimental groups. According to the findings, bacterial infection caused 47% loss of cells, while nontoxic ozone was found to protect the cells by 27%. Again, while bacterial infection increased apoptotic cells in different processes, ozone was found to significantly reduce this rate. At the same time, ozone suppressed the rate of necrosis caused by bacteria. It was also found that bacterial stimulation of caspases (1, 3, 8 and 12), which were effective in the initiation of apoptosis and necrotic processes and in the formation of cell loss, were suppressed by ozone pre-administration and mostly at the level of protein translation. According to the obtained data, Yersinia ruckeri infection caused cell loss in the macrophages of rainbow trout by stimulating both apoptosis and necrosis. However, nontoxic ozone significantly improved this negative situation. In this context, it has come to the conclusion that nontoxic ozone can be used as a safe and effective treatment alternative for increasing host defenses and eliminating the infection in the case of yersiniosis in fishes. However, in order for this argument to be fully understood, it is inevitable to support it with advanced molecular and in vivo studies.

The environmental factors that affect the seasonal change of the phytoplankton community and composition in Karkamis Dam Lake were investigated on samples taken from five stations between January 2015 and December 2015. It was found that the phytoplankton of Karkamis Dam Lake consisted of 85 taxa belonging to Bacillariophyta (56 taxa), Chlorophyta (15 taxa), Chrysophyta (1 taxon), Cyanophyta (10 taxa), Dinophyta (2 taxa) and Euglenophyta (1 taxon). Members of Bacillariophyta and Chrysophyta increased well during spring, summer and also at the end of fall whilst Chlorophyta grew well only in summer and fall. Cyanophyta became dominant at the end of spring and in summer. However Dinophyta was remarkably conspicuous in winter as well as in spring and fall in terms of prevalence. Excessive reproduction of Cyanobacteria, which is a characteristic aspect of mesotrophic lakes, was observed in Karkamis Dam Lake in both May and July. Results of physical and chemical measurements and analysis indicated that the lake was mesotrophic based on PCA and Carlson trophic state index. Phytoplankton composition was found to be affected by environmental factors such as temperature, pH, dissolved oxygen, phosphate and nitrate through the year. Using these data, a strong model was developed for sustainable management in Karkamis Dam Lake.

Continuous exposure of Nile tilapia to 1.5 mg/L concentration of copper sulfate in water solution for three periods (35, 65 and 95 days) decreased the total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose (except the elevation in the exposed group at the end of 95 days period), magnesium (Mg+2), calcium (Ca+2), iron (Fe+2), potassium (K+), sodium (Na+1), chloride (Cl-) and phosphate values in serum. The cholesterol, low density lipid (LDL), triglyceride, globulin, creatinine, alkaline phosphatase (ALP), total bilirubin, direct bilirubin, uric acid and blood urea nitrogen (BUN) concentrations in the serum increased in copper sulfate-exposed fish.

Kutlu, Banu
In order to determine the effects of nutrient (P, Si, NH4, NO3) enrichment on the growth of phytoplankton in Homa Lagoon (İzmir Bay, Aegean Sea), experiments of enrichment with discontinuous cultures have been executed seasonally in 2007. In our study, the elements limiting the growth of phytoplankton were NO3, P and Si in spring season, N and P in summer season, and NH4 in autumn and winter seasons. So, it has been determined that the addition of nitrogen (N) and phosphor (P) has led significant change in biomass and growth of phytoplankton. It has also been observed that diatom and dinoflagellate species have grown under various concentrations of, especially, Silicate (Si) and nitrogen (N).
