Phenoxyethanol-Based Embalming for Anatomy Teaching: An 18 Years' Experience with Crosado Embalming at the University of Otago in New Zealand
Peer reviewed Peer reviewed
Direct linkDirect link
Crosado, Brynley; Löffler, Sabine; Ondruschka, Benjamin; Zhang, Ming; Zwirner, Johann; Hammer, Niels – Anatomical Sciences Education, 2020
Embalming fixatives such as formaldehyde and phenol have been associated with occupational health hazards. While anatomists aim at replacing these chemicals, this seems presently unfeasible in particular for formaldehyde. Furthermore, fixation protocols usually require well-equipped facilities with highly experienced staff to achieve good fixation…

Warren, David S.; Sutherland, Sam P. H.; Kao, Jacqueline Y.; Weal, Geoffrey R.; Mackay, Sean M. – Journal of Chemical Education, 2017
Samples of a composite hydrogel incorporating clay (Laponite XLG and S-482) nanoparticles were prepared using N-isopropylacrylamide. The hydrogels were formed via a radical-initiated addition polymerization using potassium persulfate and N,N,N',N'-tetramethylethylenediamine. Students then measured the force required to stretch the gels and…

Pather, Nalini; Blyth, Phil; Chapman, Jamie A.; Dayal, Manisha R.; Flack, Natasha A.M.S.; Fogg, Quentin A.; Green, Rodney A.; Hulme, Anneliese K.; Johnson, Ian P.; Meyer, Amanda J.; Morley, John W.; Shortland, Peter J.; Štrkalj, Goran; Štrkalj, Mirjana; Valter, Krisztina; Webb, Alexandra L.; Woodley, Stephanie J.; Lazarus, Michelle D. – Anatomical Sciences Education, 2020
Australian and New Zealand universities commenced a new academic year in February/March 2020 largely with "business as usual." The subsequent Covid-19 pandemic imposed unexpected disruptions to anatomical educational practice. Rapid change occurred due to government-imposed physical distancing regulations from March 2020 that…

Glucose Transport into Everted Sacs of the Small Intestine of Mice
Peer reviewed Peer reviewed
Direct linkDirect link
Hamilton, Kirk L.; Butt, A. Grant – Advances in Physiology Education, 2013
The Na[superscript +]-glucose cotransporter is a key transport protein that is responsible for absorbing Na[superscript +] and glucose from the luminal contents of the small intestine and reabsorption by the proximal straight tubule of the nephron. Robert K. Crane originally described the cellular model of absorption of Na[superscript +] and…

Stereochemical Control in Carbohydrate Chemistry
Peer reviewed Peer reviewed

Batchelor, Rhys; Northcote, Peter T.; Harvey, Joanne E.; Dangerfield, Emma M.; Stocker, Bridget L. – Journal of Chemical Education, 2008
Carbohydrates, in the form of glycoconjugates, have recently been shown to control a wide range of cellular processes. Accordingly, students interested in the study of organic chemistry and biomedical sciences should be exposed to carbohydrate chemistry. To this end, we have developed a sequence of experiments that leads the student from the…

Photosynthesis and Respiration in Leaf Slices.
Peer reviewed Peer reviewed
Brown, Simon – Biochemical Education, 1998
Demonstrates how leaf slices provide an inexpensive material for illustrating several fundamental points about the biochemistry of photosynthesis and respiration. Presents experiments that illustrate the effects of photon flux density and herbicides and carbon dioxide concentration. (DDR)

TEACHER INFLUENCE, PUPIL ATTITUDES, AND ACHIEVEMENT.
FLANDERS, NED A. – 1960
THE SPONTANEOUS BEHAVIOR OF A TEACHER AND HOW THIS BEHAVIOR AFFECTS LEARNING IN THE CLASSROOM WERE INVESTIGATED. INDEPENDENT VARIABLES IN THE STUDY WERE DIRECT TEACHER INFLUENCE, AND THE NATURE OF THE SPECIFIC LEARNING TASK. THE DEPENDENT VARIABLES WERE THE ACTUAL MEASURES OF LEARNING, INCLUDING AWARENESS OF FACTS, APPLICATION OF PRINCIPLES TO…
