The accidental discovery, in an inguinal hernia, of a male gonad in a 67-year-old woman is reported. The association of an unambiguous female phenotype with a purely male karyotype and a male gonad suggests the diagnosis of testicular feminisation. The differential diagnosis, particularly of testicular feminisation with true hermaphroditism, is discussed.

Sea cucumber is presented as potential marine source of antimicrobial compounds. The purpose of this study is to evaluate antifungal effects of sea cucumber, Holothuria leucospilota, extracts on Aspergillus niger and Candida albicans. Methanol and chloroform extracts of the body wall, gonad and intestine of sea cucumber, H. leucospilota, collected from Persian Gulf, were evaluated for their ant...

During development, complex organs are formed from individual cells and simple tissues. Organogenesis is characterized by many cellular behaviors, including cell migration, modification of cell contacts, changes in cell shape, cell proliferation and cell death. Extensive communication between cells ensures that different cell types act together in a coordinated manner to form a properly pattern...

This study was aimed to examine the different natural feeds on maturnity of freshwater crayfish. The conducted November 20th - January 21th 2021 in UPTD BBI Lukup Badak, Takengon, Aceh Tengah. Test fish used is seed cherax quadricarinatus measuring 52-75 g. Methods this Completely Randomized Design (CRD) with 4 treatments and 3 replications. were P1 (Tubifex), P2 (505 tubifex, 255 carrots, 25% ...

Background: Evidence suggests that children are more susceptible to radiation risks or hazards. In particular, their gonads are more sensitive to the effects of radiation, especially at or below reproductive age. Protecting the gonads of children and adults is of particular importance to the imaging. Aim: To investigate level of the use of gonad protection during paediatric abdomen and pelvic X...

The zinc finger transcription factor Gata4, is associated with gonadal development in many species. The present study characterizes temporal and spatial localization of Gata4 throughout gonadogenesis in porcine embryos. Immunohistochemical studies illustrated that Gata4 protein is present in the coelomic epithelium prior to histological differentiation of the nascent bipotential gonad, marking ...

BACKGROUND Our knowledge on zebrafish reproduction is very limited. We generated a gonad-derived cDNA microarray from zebrafish and used it to analyze large-scale gene expression profiles in adult gonads and other organs. METHODOLOGY/PRINCIPAL FINDINGS We have identified 116638 gonad-derived zebrafish expressed sequence tags (ESTs), 21% of which were isolated in our lab. Following in silico n...
