Hyaluronidase from Tadpole Tissue.
The connective tissues of the tadpole undergo extensive remodeling during metamorphosis. In the resorbing tail fins of bullfrog tadpoles, there is a rapid degradation of collagen in the basement lamella coupled with dehydration and loss of the gelatinous core of the fin (1,2). The layers of the dense collagenous basement lamella are loosened, frayed, and invaded by mesenchymal cells.1 A collage...
متن کاملAngle-closure, pupil dilatation, and pupil block.
PREVious papers (Lowe, 1964a) have remarked that when the pupils of eyes with shallow anterior chambers, narrow angles, and open peripheral iridectomies are dilated with homatropine, a considerable proportion of the eyes with persistently narrow angles develop angle-closure, a consequent fall in outflow facility, and a rise in intra-ocular pressure that may reach the fifties within two hours. W...
متن کاملOptimum Teacher-Pupil Interaction for Pupil Growth"
BOTH hypotheses and conclusions relating teacher-pupil behavior to pupil growth tend to be stated in simple, declara tive sentences, as: "Increased teacher indi rectness is associated with increased pupil growth in subject matter and more favor able attitudes"; or, "Decreased teacher criti cism is associated with more favorable pu pil attitudes and increased subject-matter growth." Yet probably...
متن کاملTadpole-like artificial micromotor.
We describe a polymer-based artificial tadpole-like micromotor, which is fabricated through the electrospinning technique. By incorporating functional materials onto its surface or within its body, the resulting tadpole-like micromotor can not only move autonomously in an aqueous solution with a flexible tail, but also exhibit thermo- and magnetic responsive properties.
متن کاملTadpole tail regeneration in Xenopus.
Some organisms have a remarkable ability to heal wounds without scars and to regenerate complex tissues following injury. By gaining a more complete understanding of the biological mechanisms that promote scar-free healing and tissue regeneration, it is hoped that novel treatments that can enhance the healing and regenerative capacity of human patients can be found. In the present article, we b...
