Increased use of fertilizers to increase plant production causes important environmental pollution not only in soil but also in water resources. Soil structure, water quality, water systems, and biodiversity are adversely affected by the unconscious use of fertilizers. In this study, Capoeta capoeta (Guldenstaedt 1773) were used to investigate the degenerative effects of nitrogen fertilizer. Twentyfour fish were equally allocated into three groups; group 1 (control), group 2 (15 mg/L nitrogen fertilizer in water) and group 3 (15 mg/L nitrogen fertilizer in water). Fish were exposed to the fertilizer for 15 days and then the tissues of gill, liver and …

The water quality of rivers located in areas close to major cities is deteriorating significantly due to increased pollution. The Karasu River, which passes through Erzurum city Turkey, is getting polluted day by day due to domestic and industrial wastewater. In the study, various assessments were made in three different fish species to determine the impact of possible contamination here. Capoeta capoeta, Alburnus mossulensis and Squalius cephalus were caught from four stations of the river. Micronucleus test was applied to find out genotoxic alterations, and plasma total oxidant status (TOS) and total antioxidant status (TAS) were measured to determine oxidative …
Dna Damage, Oxidative Stress, Decreased Viability And Motility In Common Carp (Cyprinuscarpio L.) Spermatozoa Induced By Tryptophan, Phenylalanine And Cysteine Amino Acids During Short-Term Storage, Mahi̇r Kanyilmaz, Burak Evren İnanan
Dna Damage, Oxidative Stress, Decreased Viability And Motility In Common Carp (Cyprinuscarpio L.) Spermatozoa Induced By Tryptophan, Phenylalanine And Cysteine Amino Acids During Short-Term Storage, Mahi̇r Kanyilmaz, Burak Evren İnanan

Free amino acids are found in spermatozoa and seminal plasma. Their qualitative and quantitative presence have been affected by many factors. Under in vitro storage conditions, their effects on spermatozoa in animal species and also human have been concerned over the last decades. In this study, the effects of tryptophan, phenylalanine and cysteine on DNA integrity, lipid peroxidation, viability and motility parameters in spermatozoa of the common carp (Cyprinuscarpio) were assessed during short-term storage. Spermatozoa were incubated at 1, 5, 25, and 50 mM of these amino acids in vitro at 4 °C in a time?dependent manner (6, 24, and …

Obesity is an important public health problem and a risk factor for many chronic diseases, and its prevalence is increasing rapidly. In recent years there has been interest in the impact of nutrients on obesity and this has been addressed as a research topic. Bee bread is a bee product that has recently attracted attention with its macro- and micronutrients and the enzymes and biocomponents it contains. Although there are many studies on the biological properties and effects of bee bread, its effect on obesity with leptin and ghrelin has not been investigated. In this study, 40 Sprague-Dawley adult female …

Wound healing is a complex process affected by various conditions, including oxidative stress. The present study explored the time-dependent effects of platelet-derived growth factor (PGDF) and vascular endothelial growth factor (VEGF) administration on oxidative markers during acute stage wound healing. Thirty-six Wistar rats were distributed into three major groups; skin wounds were inflicted in all groups. The wounds were either left untreated (control group), treated topically with blank chitosan gel (blank chitosan gel group), or treated topically with a combination of PDGF and VEGF in chitosan gel (PDGF + VEGF chitosan gel group). Wounds were sampled on postsurgery days 3 …
