BACKGROUND Few reports have described the ophthalmic complications that occur after maxillary orthognathic surgery. Since cases of decreased reflex tearing after maxillary orthognathic surgery are extremely rare, we describe 2 cases of loss of reflex tearing after maxillary orthognathic surgery. CASE PRESENTATION Two Asian women, an 18-year-old and a 32-year-old, suffered from unilateral dryn...

isassembly of the mitotic spindle takes some effort, according to Kan Cao, Yixian Zheng (Johns Hopkins University, Baltimore, MD), and colleagues, who show that an ATPase and its binding partners pull apart the spindle. The spindle is put together by assembly factors that are activated by the cyclin-dependent kinase Cdc2. The loss of Cdc2 activity at the end of mitosis has thus been the convent...

Recent advances in scale-free networks have claimed that their topologies are very weak against attacks. The inhomogeneous connectivity distribution of large-scale current communication networks, such as the Internet, could be exploited by evil hackers in order to damage these systems. However, there have not been many studies on the approaches and consequences of such targeted attacks. In this...

Among different physical simulation topics, cloth simulation is one of the most popular subjects in computer graphics. There are many different studies published on different aspects of cloth simulation, but there are not many studies focused on the tearing of cloth. Existing studies related to this topic have only dealt with some aspects of the problem [Metaaphanon et al. 2009] and have not pr...

Numerical studies of the nonlinear evolution of magnetohydrodynamic–type tearing modes in three-dimensional toroidal geometry with neoclassical effects are presented. The inclusion of neoclassical physics introduces an additional free-energy source for the nonlinear formation of magnetic islands through the effects of a bootstrap current in Ohm’s law. The neoclassical tearing mode is demonstrat...

Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both ...

We propose an efficient method to model paper tearing in the context of interactive modeling. The method uses geometrical information to automatically detect potential starting points of tears. We further introduce a new hybrid geometrical and physical-based method to compute the trajectory of tears while procedurally synthesizing high resolution details of the tearing path using a texture base...

Tearing of the distal triceps is uncommon and may be difficult to diagnose, especially in situations of partial tearing. Imaging methods such as ultrasonography and magnetic resonance imaging should be used to confirm the diagnosis and define the extent of the injury. The preferred treatment for complete tearing of the triceps is surgical, unlike in cases of partial tearing, in which the treatm...

PURPOSE Lacritin is a novel human tear glycoprotein that promotes basal tear peroxidase secretion by rat lacrimal acinar cells in vitro. This study investigates whether lacritin is prosecretory when added topically to the ocular surface of normal living rabbits, and if so, what is its efficacy and tolerability versus cyclosporine and artificial tears. METHODS Purified recombinant human lacrit...

Electron temperature fluctuations are correlated with the dominant (m, n) = (0, 1) edge-resonant magnetic tearing mode during sawtooth events in the Madison Symmetric Torus reversed-field pinch. Electron temperature fluctuations in phase with the (0, 1) tearing mode are measured using highrepetition-rate Thomson scattering. Immediately prior to the sawtooth the (0, 1) island structure appears t...
