Study of living frog oocytes with the phase microscope has shown that the early yolk appears in two forms. One of these, the protein yolk, consists of thin, dense, plate-like bodies which in face view are almost always regular hexagons. The other form, the fatty yolk, occurs as clusters of globules of varying sizes. The plate-like bodies occur both singly and in clusters. As the oocytes mature ...

Most vertebrate oocytes contain a Balbiani body, a large, non-membrane-bound compartment packed with RNA, mitochondria, and other organelles. Little is known about this compartment, though it specifies germline identity in many non-mammalian vertebrates. We show Xvelo, a disordered protein with an N-terminal prion-like domain, is an abundant constituent of Xenopus Balbiani bodies. Disruption of...

The endangered epiphytic orchid, Dendrobium chrysotoxum, is known for its ornamental and medicinal uses. However, knowledge of this orchid’s symbiotic seed germination, protocorm anatomy, developmental morphology completely unknown. In study, we investigated the process development D. chrysotoxum during germination using anatomical technologies scanning electron microscopy. There are six stages...

By light microscopic observation of the mouse brain impregnated by the Holmes' method, intensely stained cytoplasmic inclusion bodies were demonstrated in the nerve cells of the hypothalamus, locus coeruleus and other autonomic regions in addition to the limbic system and some circumventricular organs. Electron microscope observation of ultrathin sections made from vibratome sections impregnate...

A 65-year-old female presenting with hepatobiliary cystadenoma (HC) comprised of multiple cysts in the liver and a non-specific epigastric pain is reported herein.  Ultrasound study demonstrated dilated common bile duct (CBD) and intrahepatic bile ducts, plus two spherical stone-like bodies filling defects in the proximal CBD. Sphincterotomy and basket performed for the patient were not success...

BACKGROUND AND AIMS The endangered leafless ghost orchid, Dendrophylax lindenii, one of the most renowned orchids in the world, is difficult to grow under artificial conditions. Published information on asymbiotic and symbiotic (co-culture with a mycobiont) seed germination, seedling anatomy and developmental morphology of this leafless orchid is completely lacking. This information is critical...
