PURPOSE During deep anterior lamellar keratoplasty (DALK), endothelium and Descemet's membrane are separated from the corneal stroma by intrastromal air injection ('big-bubble technique'). The aim of our study is to analyse histopathological changes in host corneal tissue caused by air insufflation in patients with keratoconus, their variability in 10 patients and their possible clinical implic...
PURPOSE The purpose of this study was to evaluate the ability of second-harmonic imaging to identify differences in corneal stromal collagen organization between normal human and keratoconus corneas. METHODS Six normal corneas from eye bank donors and 13 corneas of patients with keratoconus, obtained after penetrating keratoplasty were examined. A femtosecond titanium-sapphire laser with 800-...
Protease K1 activity initiates the degradation of the Kunitz soybean trypsin inhibitor (KSTI) during germination and early seedling growth. This enzyme was purified nearly 1300-fold from the cotyledons of 4-day-old soybean (Glycine max [L.] Merrill) seedlings. Protease K1 is a cysteine protease with a molecular weight of approximately 29,000. It cleaves the native form of KSTI, Ti(a), to Ti(a) ...
The 2014 Virtual Reality Technical Achievement Award goes to Doug A. Bowman of the Center for Human-Computer Interaction at Virginia Tech, USA, in recognition of research and design achievements that have significantly advanced knowledge in the fields of 3D user interfaces and virtual reality. Professor Bowman’s work on 3D UIs has resulted in both important interaction technique designs and a d...

The problem of the causative agent of epidemic influenza, and especially that of the importance of Pfeiffer's Bacillus influenzce, until recently generally believed to be the infecting organism in this disease, seems still far from solution. Of late, much attention has been directed to the search for a filterable virus, and success has been reported by a number of independent workers. Nicolle a...
The three-dimensional structure of the Bowman-Birk type proteinase inhibitor (PI-II) has been determined by x-ray crystallography and refined at 2.5-A resolution. This protein is a specific inhibitor of trypsin. Two reactive site loops, one at each end of the PI-II molecule, are structurally similar to each other and to reactive-site loops of pancreatic secretory trypsin inhibitor (Bolognesi, M...
