Management of subluxated cataract with capsule anchor implantation

We describe a small case series that provides preliminary evidence of the usefulness of a new capsule-anchoring device for the management of subluxated cataracts. Three eyes of 3 patients with traumatic subluxated cataract causing a significant visual loss were enrolled. Phacoemulsification was performed in all cases with implantation of a capsule-anchoring device (AssiAnchor) because partial zonular dehiscence was present. A significant visual improvement was achieved in the 3 cases. The capsular bag was well centered and the anchors firmly attached to the capsulorhexis and sclera at 12 months postoperatively. The capsule-anchoring device was helpful in managing traumatic subluxated cataracts, enabling effective centration of the intraocular lens–capsular bag complex and, consequently, effective visual restoration.

Stress crrosion cracking fracture mechanisms in rock bolts

Rock bolts have failed by Stress Corrosion Cracking (SCC). This paper presents a detailed examination of the fracture surfaces in an attempt to understand the SCC fracture mechanism. The SCC fracture surfaces, studied using Scanning Electron Microscopy (SEM), contained the following different surfaces: Tearing Topography Surface (TTS), Corrugated Irregular Surface (CIS) and Micro Void Coalescence (MVC). TTS was characterised by a ridge pattern independent of the pearlite microstructure, but having a spacing only slightly coarser than the pearlite spacing. CIS was characterised as porous irregular corrugated surfaces joined by rough slopes. MVC found in the studied rock bolts was different to that in samples failed in a pure ductile manner. The MVC observed in rock bolts was more flat and regular than the pure MVC, being attributed to hydrogen embrittling the ductile material near the crack tip. The interface between the different fracture surfaces revealed no evidence of a third mechanism involved in the transition between fracture mechanisms. The microstructure had no effect on the diffusion of hydrogen nor on the fracture mechanisms. The following SCC mechanism is consistent with the fracture surfaces. Hydrogen diffused into the material, reaching a critical concentration level. The thus embrittled material allowed a crack to propagate through the brittle region. The crack was arrested once it propagated outside the brittle region. Once the new crack was formed, corrosion reactions started producing hydrogen that diffused into the material once again.

GPI-Anchor synthesis: Ras takes charge

A new study shows that Ras2 regulates GPI-anchor synthesis in the ER. Reciprocally, the targeted enzyme GPI-GlcNAc transferase regulates Ras2 signal output. This novel intersection of Ras2 signaling and an ER-localized protein complex has interesting implications for Ras function.
