In brain and gonad
of female, a slightly increase in Er[alpha] expression was observed after exposure to LET for 5d, but it decreased rapidly at all groups for 10d or 15d.
Differences in the frequency of parasitized and nonparasitized clams (prevalence) for each gonad
development stage (rest, development, ripe, spawning, and spent) and season of the year were evaluated using a chi-square test ([chi square]).
In the gonad
samples, the comparison in the concentrations of HMs among three species of fish where Pb levels ranged from 2.
complex were identified based on the characteristics described by Miller (1992) in male Gobiidae as a testicular gland and by Asoh and Shapiro (1997) for G.
Immediately after, some prawns were conserved intact for the chemical analysis in whole animals and the others were dissected to remove the gonads
, the hepatopancreas, and the abdominal muscle.
Quantification of the moisture, protein, lipid, carbohydrate and ash content of both the gonad
were carried out following the methodologies described in the AOAC (2002).
A Diagnosis of Asymmetrical gonadal dysgenesis was made and advised for bilateral gonadectomy since chances for development of malignancy in gonads
are very high.
Out of 81 ncRNAs varied significantly between control and Zinc stressed male gonad
57 of them were down-regulated up to 4.
were observed in all experimental groups except the control.
The relationship of the oxidant (MDA) and antioxidant (GSH-Px) status in hepatopancreas, gonad
and muscle tissues of sexually maturating A.
A segment from the mid-region of one lobe (either left or right, random choice, including lumen and gonad
wall) was then cut and placed in a histology cassette and sent to a contracted laboratory for further processing.
Our objective in this study is to contribute to improve the management of mutton snapper caught by the artisan fishing fleet of Northeast Brazil, providing information about the sex structure, gonad
development, spawning mode and seasonality of reproduction.
We used the fetal gonad
organ culture system previously developed by our group coupled with morphologic, functional, and molecular methods (Lambrot et al.
The chromosomal sex determines what type of gonad
develops in the embryo.
but, information on the impact of live food, pelleted feeds, or a mixed diet on growth, gonad
development, and reproductive performance in tropical fishes are scanty.
