| organochlorine pesticide and polychlorinated biphenyls levels in fish and mussel in van region, turkey. | forty-seven fish (24 endemic alburnus tarichi, güldenstädt, 1814; 8 capoeta capoeta, guldenstaedt, 1772; 15 mirror carp cyprinus carpio, l., 1758) and 13 mussel (unio stevenianus, krynicki, 1837) samples, with 10 specimens per sample, were collected from van lake, turkey, and rivers flowing into it. gamma-hch was detected in 21 alburnus tarichi samples (56.57 ng/g ± 22.18 ng/g) and in two capoeta capoeta samples (27.6 ng/g and 36.45 ng/g). beta-hch was detected in 8 alburnus tarichi samples (24. ... | 2011 | 21516453 |
| alterations in histology and antioxidant defense system in the testes of the lake van fish (alburnus tarichi güldenstädt, 1814). | recent reports have demonstrated gonadal abnormalities in the lake van fish (alburnus tarichi) from lake van caused by increasing pollution. in the present study, the fish was collected from an area of lake van receiving mainly sewage treatment plant effluent at prespawning period (april) and from a river (karasu) which is close to the polluted area of the lake and where the fish migrates at spawning period (may). collected specimens were examined for testicular alterations, gonadosomatic index ... | 2016 | 27435621 |
| relation between increased oxidative stress and histological abnormalities in the ovaries of alburnus tarichi in lake van, turkey. | recent studies have shown reproductively arrested gonad development in female alburnus tarichi (güldenstädt, 1814) (cyprinidae) from the eastern coastline of lake van, turkey, due to increasing pollution. in the reproductively arrested females (raf), oocytes were developmentally blocked and arrested at the previtellogenic stage and gonadosomatic indices (gsi) were very low, while reproductively non-arrested females (rnf) found at the same site displayed relatively normal ovarian development and ... | 2015 | 26497562 |
| investigation of the irisin, preptin and adropin levels in the blood serum of alburnus tarichi. | irisin, preptin and adropin are three newly discovered peptides that play critical roles in regulating energy homeostasis in various vertebrates.the purposes of this study were to measure the serum concentrations of preptin, adropin and irisin in the alburnus tarichi and to investigate the relationship of these peptides to the weight, gender and length of this the fish, which will provide useful information for future biotechnology purposes aimed at improvements in aquaculture production. this s ... | 2017 | 28886320 |
| isolation of estrogen receptor subtypes and vitellogenin genes: expression in female chalcalburnus tarichi. | reproductively arrested gonadal development has been previously described in the teleost pearl mullet (chalcalburnus tarichi, cyprinidae) from van edremit gulf of lake van, turkey. oocyte development in some females was arrested at the previtellogenic stage, while gonadosomatic index (gsi) and plasma 17β-estradiol (e2) level were low. a subset of the females was found to have normal ovaries and relatively higher plasma e2 and gsi. these two groups were termed reproductively arrested (ra) and rep ... | 2014 | 24747933 |
