The development of an epithelial tumor, especially mucinous type, in a female with a streak gonad is rare and not fully understood. We report a case of a 19-year-old; a single female known to have Turner syndrome presented with an increased abdominal girth and was found to have a huge pelvic and abdominal mass. Ultrasound and magnetic resonance imaging revealed a huge cystic ovarian mass with n...
This study aimed to investigatethe changes in Gonad Somatic Index (GSI), vitellogenin induction and ovarian histopathology in zebrafish (Danio rerio) adult female, as an ecological model in toxicology, after exposure to 0.002, 0.02, 0.2, 2 and 20 µg/L cadmium chloride for 21 days under sub-lethal condition. The results showed that 0.002 to 20 µg/L cadmium chloride had no significant effect on t...
A method to mitigate or possibly eliminate reproduction in farmed fish is highly demanded. The existing approaches have certain applicative limitations. So far, no immunization strategies affecting gonadal development in juvenile animals have been developed. We hypothesized that autoimmune mechanisms, occurring spontaneously in a number of diseases, could be induced by targeted immunization. We...
Striped catfish tetraploid induction through heat shock that carried out in this study is not intended to produce on growth fries.But form a broodstock triploid fries cross breeding without any physical process.The from the previous were screened or selected by observing maximum number of nucleoli fin cells.The individuals used performance test was 105 which placed three different concrete tank...
In deserts where unpredictable rainfall arises and a large variation in temperature occurs, this poses severe energetic and water related constraints on reproduction in small mammals and makes the use of photoperiod as cue for reproduction unreliable. In the present study, the gonad morphometrics, gonadal histology and endocrine profiles of the Arabian spiny mouse (Acomys dimidiatus) were studi...
The mola carplet, Amblypharyngodon (Hamilton, 1822) is the most common small indigenous freshwater fish species in Bangladesh. precise information addressing reproduction this including breeding peak, ovarian histology, morphometry, and sex ration nature still insufficient. A one yearlong filed survey different laboratory assays have been directed to disclose some key features of female A. from...
OBJECTIVE To establish the spectrum of presentation, natural history and gynaecological outcomes in women with Swyer syndrome. DESIGN Retrospective notes review. SETTING Tertiary referral centre for disorders of sex development. POPULATION A total of 29 adult women with Swyer syndrome. METHODS Information was collected on age at diagnosis, biometric characteristics, timing of gonadectom...
background: gonad shielding has been recommended during pelvic x-rays since the 1950s. the popular method of gonad shielding is placement a lead shield in the midline of the pelvis. the aim of this study was to evaluate the prevalence and utility of gonad shielding in pediatrics undergoing pelvic x-rays.materials and methodsfollowing study approval, we retrospectively retrieved data from the di...
aquatics are a source of bioactive compounds that these compounds have different properties such as antimicrobial activity. in this study, antibacterial activity of methanol, chloroform and hexane extracts from body wall, gonad and intestine of sea cucumber holothuria leucospilota was evaluated against bacillus subtilis, pseudomonas aeruginosa and staphylococcus aureus. bioactive compounds of b...
