The aim of this study was to investigate the effects of prolonged oral administration of α -naphthoflavone on somatic and germinal development in male and female chickens (Gallus domesticus). No signi...
A newly discovered, nonoccluded baculovirus GSV has been reported to be a causative agent of sterility in adult corn ear-worms, Helicoverpa zea. Previous studies conducted by Hamm et al. (1996) and ou...
A polymerase chain reaction (PCR) primer set for a chicken microsatellite locus on the Z chromosome, LEI0171 (GenBank Accession No.X85538), amplified a 363bp fragment of genomic DNA in chickens (Gallu...
Effects of estradiol-17β (E2) and p-nonylphenol (NP) on mRNA expression of estrogen receptor α (ERα), estrogen receptor β (ERβ) and cytochrome P450 aromatase (P450arom) were examined in the early stag...
Effects of estradiol-17β (E2) and p-nonylphenol (NP) on the mRNA expression of sex determination-related genes were examined in the embryonic gonad of chickens. Fertilized eggs were treated with eit...
Primordial germ cells (PGCs) of white leghorn Maria line hens embryos as a donor were transferred white leghorn Laura line hens embryos as a recipient. During stage 12 to 15 of incubating fertilized ...
A sensitive radiometric assay was developed for detecting phospholipase A1 and A2 (PLA1 and A2) activity. Four to five times more PLA2 activity was observed in rat testes than PLA1 activity. Two PLA...
The histological changes of gonads were studied in Aphanius persicus from the Barm-e-Shoor spring (south of Iran). The gonads were extracted and prepared histologically. The maturity stage of each spe...

In the present work, gonad development and sex ratio of sharptooth catfish (Clarias gariepinus) cultured under laboratory conditions over 365 days from hatching were investigated histologically and mo...
Chick embryos from stage 14 to stage 31 were studied by means of serial section and light microscopy in order to learn the relationship between the settlement sites of the primordial germ cells (PGCs)...
The relationship of gonad weight and liver weight with body weight of six fish species viz; Catla catla, Labeo rohita, Cirrhina mrigala, Hypophthlamichthys molitrix, Ctenopharyngodon idella and Cyprin...
In this study, gonad development of Chalcalburnus tarichi, an anadromus, endemic fish species of the Lake Van and its inlets was histologically investigated. During oogenesis, six different developmen...
