Miniaturized Bioaffinity Assessment Coupled to Mass Spectrometry for Guided Purification of Bioactives from Toad and Cone Snail

open access: yesBiology, 2014
A nano-flow high-resolution screening platform, featuring a parallel chip-based microfluidic bioassay and mass spectrometry coupled to nano-liquid chromatography, was applied to screen animal venoms for nicotinic acetylcholine receptor like (nAChR ...

MUCOR AMPHIBIORUM IN THE TOAD, BUFO MARINUS, IN AUSTRALIA [PDF]

open access: yesJournal of Wildlife Diseases, 1994
Mucor amphibiorum, a fungus previously found in captive amphibians in Europe and the platypus in Australia, was observed in free-ranging toads, Bufo marinus, in Australia. In tissues the fungus occurred as sphaerules 4.9 to 36.4 microns in diameter; hyphae were not formed. Some spharules developed two to 11 daughter sphaerules internally and these were

Evidence for the Use of Bufo marinus in the Olmec Shamanic Tool Kit

open access: yes, 2009
This thesis explores the use of toad imagery in Olmec iconography. The Bufo marinus, secretes a highly toxic poison that, when used with discretion, has hallucinogenic properties.

Helpful invaders: Can cane toads reduce the parasite burdens of native frogs?

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2015
Many invading species have brought devastating parasites and diseases to their new homes, thereby imperiling native taxa. Potentially, though, invaders might have the opposite effect. If they take up parasites that otherwise would infect native taxa, but

Electrical responses of rods in the retina of Bufo marinus

open access: yesThe Journal of Physiology, 1977
1. Intracellular responses to flashes and steps of light have been recorded from the outer segment and the cell body of rods in the retina of the Bufo marinus. The identification of the origin of recorded responses has been confirmed by intracellular marking.2.

Sox9 and Vasa Gene Expression During Gonadal Differentiation in Larvae of the Urodele Amphibian Ambystoma mexicanum

open access: yesActa Zoologica, EarlyView.
ABSTRACT The study of genes involved in sexual differentiation, as Vasa and Sox9, is of great importance, as they serve as specific markers for the germline and the male differentiation pathway, respectively. This study characterized using immunofluorescence the expression of the Vasa and Sox9 genes and laminin during gonadal differentiation in larvae ...

Evidence toads may modulate landing preparation without predicting impact time

open access: yesBiology Open, 2017
Within anurans (frogs and toads), cane toads (Bufo marinus) perform particularly controlled landings in which the forelimbs are exclusively used to decelerate and stabilize the body after impact. Here we explore how toads achieve dynamic stability across
