Accumulation and Elimination of Cadmium by the Nile Tilapia (Oreochromis niloticus) in differing Temperatures and Responses of Oxidative Stress Biomarkers

FAHRİ KARAYAKAR | BEDİİ CİCİK

The aims of this study were to investigate the accumulation (15 days) and elimination (15 and 30 days) of cadmium (Cd) in the liver, gill, kidney and muscle of Oreochromis niloticus following exposures to different concentrations (1 and 2 mg/L) of Cd at different water temperatures (20, 25, 30 o C). Additionally, responses of oxidative stress biomarkers (superoxide dismutase, SOD; catalase CAT; glutathione peroxidase, GPx and malondialdehyde, MDA) of the liver were determined following Cd exposures. In accumulation period, Cd levels increased significantly in all the tissues at all temperature ...Daha fazlası

Prophylactic efect of myricetin and apigenin against lipopolysaccharide‑induced acute liver injury

FAHRİ KARAYAKAR | FERBAL ÖZKAN YILMAZ | ARZU ÖZLÜER HUNT

Background Liver has an important role in the initiation and progression of multiple organ failure that occurs in sepsis. Many natural active substances can be used to reduce the liver injury caused by sepsis. For this aim, the efects of myricetin and apigenin on mice model of acute liver injury was evaluated in this study. Methods and results Thirty-six mice were randomly divided into six groups as; control, lipopolysaccharide (LPS) (5 mg/kg), LPS+myricetin (100 mg/kg), LPS+myricetin (200 mg/kg), LPS+apigenin (100 mg/kg), and LPS+apigenin (200 mg/kg) groups. Myricetin and apigenin were admini ...Daha fazlası

Changes in Liver Tissue Trace Element Concentrations During Hepatitis B Viral Infection Treatment

FAHRİ KARAYAKAR | TAHSİN ÇOLAK

Approximately 350–400 million people in the world have Hbs Ag (hepatitis B virus surface antigen) positivity. In the international guidelines, the permanent suppression of replication in chronic hepatitis B virus (HBV) infection therapy is reported as the primary therapeutic goal. Trace elements play a key role in liver diseases. The aim of our study is to determine some trace element concentrations in the liver during HBV treatment periods. The measurement of 11 trace elements (manganese, lead, nickel, chromium, cadmium, iron, copper, zinc, silver, cobalt, and aluminum) was carried out by the ...Daha fazlası

Eutrophication Status of the Berdan and Göksu River Basins in Turkey

İSMAİL AKÇAY | ÖZGÜR ÖZBAY | MEHMET TAHİR ALP

In this study, the eutrophication status of the Berdan and Göksu River Basins was determined by using recently obtained data between September 2021 and August 2022. Very high total phosphorus and trophic index (TRIX) values indicated that all stations visited in the Berdan, and Göksu River Basins were characterized as eutrophic (bad). The correlations between TRIX and eutrophication-related parameters showed strong and positive relations between TRIX and concentrations of Chlorophyll-a and total phosphorus strongly suggesting that the increase in total phosphorus concentrations highly enhanced ...Daha fazlası

Assessment of trophic status of the northeastern Mediterranean coastal waters: eutrophication classification tools revisited

İsmail Akçay

The Eastern Mediterranean and its Cilician Basin offshore waters have oligotrophic features with low nutrient concentrations, low primary production, and high water transparency. However, the wide shelf area of the Cilician Basin is subject to contaminated river inflows with enhanced nutrient loads and direct discharges of urban wastewaters of southern Turkey, leading to develop local eutrophic/mesotrophic conditions in the inner sites of Mersin and Iskenderun Bays on the Cilician Basin. For the assessment of changing trophic status of the coastal and the bay water bodies under anthropogenic p ...Daha fazlası

Assessment of heavy metal pollution in coastal surface sediments of the Mersin Bay, Northeastern Mediterranean Sea.

ÖZGÜR ÖZBAY

Heavy metals accumulated in the sediment constitute a potential source of pollution having a higher pollutant load than the overlying seawater. In order to determine anthropogenic impacts on the heavy metal enrichment and contamination in surface sediments, either reference/background values of the metals in the pristine condition or reference metal values of the earth’s crust are widely used. In this study, the metal pollution indices Enrichment Factor, Geoaccumulation Index, Contamination Factor and Pollution Load Index were used to determine the levels and sources of metal pollution (Chromi ...Daha fazlası

Fatty acid metabolism in European sea bass Dicentrarchus labrax effects of n 6 PUFA and MUFA in fish oil replaced diets

KENAN ENGİN

Monounsaturated fatty acids (MUFA)-rich and n-6 polyunsaturated fatty acid (n-6 PUFA)-rich vegetable oils are increasingly used as fish oil replacers for aquafeed formulation. The present study investigated the fatty acid metabolism in juvenile European sea bass (Dicentrarchus labrax, 38.4 g) fed diets containing fish oil (FO, as the control treatment) or two different vegetable oils (the MUFA-rich canola/ rapeseed oil, CO; and the n-6 PUFA-rich cottonseed oil, CSO) tested individually or as a 50/50 blend (CO/ CSO). The whole-body fatty acid balance method was used to deduce the apparent in vi ...Daha fazlası
