An abnormal embryo (male of 465 mm total length) and 13 other embryos were removed from a pregnant female bull shark (Carcharhinus leucas) caught in coastal waters between the Grijalva River Terminos Lagoon southwestern Gulf Mexico. The first record synophthalmia leucism is presented. cyclopia case reviewed.

BACKGROUND Although often associated with holoprosencephaly, little detail of the histopathology of cyclopia is available. Here, we describe the ocular findings in a case of trisomy 13 to better understand the histogenesis of the rosettes, or tubules, characteristic of the retinal dysplasia associated with this condition. METHODS A full pediatric autopsy was performed of a near term infant wh...

Hormone replacement therapy associated risks, and the concomitant reluctance of usage, has instigated the search for new generations of estrogen analogues that would maintain estrogen benefits without associated risks. Furthermore, if these analogues display chemo-preventative properties in breast and endometrial tissues it would be of great value. Both the selective estrogen receptor modulator...

in studies on teratogenesis. Fetuses afflicted with holoprosencephaly, including varying degrees of such malformations as pituitary agenesis, cyclocephaly, cyclopia and monorhinia, can be obtained by administering triparanol or AY 9944 which inhibits cholesterol synthesis. A large number of fetuses have a minor form of holoprosencephaly, i.e. limited to isolated hypophyseal agenesis. We used th...

A high-performance liquid chromatographic (HPLC) method coupled with diode-array detection (DAD) was optimized for the qualitative analysis of aqueous extracts of Cyclopia genistoides. Comprehensive insight into the phenolic profile of unfermented and fermented sample extracts was achieved with the identification of ten compounds based on comparison with authentic reference standards and the te...

The chemopreventive properties of the herbal teas rooibos (Aspalathus linearis) and honeybush (Cyclopia spp.) have been demonstrated on mouse skin in vivo but the underlying mechanisms are not clear. The aim of the current study was to determine the anti-proliferative and pro-apoptotic activity of methanol and aqueous extracts of rooibos and two Cyclopia species in different skin cells, using g...
