Moor, Beat Kaspar ; Kohut, Georges ; Bouaicha, Samy ; Grabherr, Silke ; Gautier, Emanuel ; Bergmann, Mathias ; Marcer, Nicholas ; Djonov, Valentin

In: Journal of Shoulder and Elbow Surgery, 2011, vol. 21, no. 5, p. 604-611

Objective: To investigate the technical feasibility of harvesting a vascularized bone graft from the acromion pedicled on the acromial branch.Background: Complex fractures of the proximal humerus may result in partial or total avascular necrosis of the head fragment. Treatment of avascular necrosis of the humeral head is dependent upon the stage of disease as well as the dimension and...

Laparoscopic training on Thiel human cadavers: A model to teach advanced laparoscopic procedures

Frésard, Isabelle ; Häfliger, André ; Bergmann, Mathias ; Krähenbühl, Lukas

In: Surgical Endoscopy, 2008, vol. 22, no. 4, p. 901-906

Background: Nowadays, the laparoscopic approach represents the gold standard for a wide range of various basic and advanced procedures. To reduce the learning curve in advanced laparoscopic surgery, the search for new teaching tools is of utmost importance. Our experiences with a new teaching tool to train advanced laparoscopic procedures are reported. Methods: Hands-on training courses in...

Expression of SV2 in the developing chick cerebellum: comparison with Calbindin and AMPA glutamate receptors 2/3

Grabs, Detlev ; Escher, Lukas ; Bergmann, Mathias

In: The Anatomical Record, 2008, vol. 291, no. 5, p. 538 - 546

The well-organized cerebellum is an ideal model to investigate the developmental appearance and localization of pre- and postsynaptic structures. One of the synaptic proteins abundant in the central nervous system and localized in presynaptic vesicle membranes is the synaptic vesicle protein 2 (SV2). SV2 was shown to be involved in priming and modulating synaptic vesicles and having an effect in...
