BACKGROUND The aim f this study was to evaluate the effect of capsular tension ring implantation during cataract surgery on the incidence of neodymium: YAG (Nd: YAG) laser posterior capsulotomy in myopic (axial length [AL] ≥25.00 mm) eyes. MATERIAL/METHODS In this retrospective study, the records of the cases of 117 myopic patients who underwent cataract surgery between January 2004 and January...

The common octopus, Octopus vulgaris, is the first invertebrate species that was shown to possess two oxytocin/vasopressin (OT/VP) superfamily peptides, octopressin (OP) and cephalotocin (CT). Previously, we cloned a GPCR (G-protein-coupled receptor) specific to CT [CTR1 (CT receptor 1)]. In the present study, we have identified an additional CTR, CTR2, and a novel OP receptor, OPR. Both CTR2 a...

P erforming cataract extraction in patients with zonular weakness presents many challenges and increases the risk of intraand postoperative complications. Capsular tension rings (CTRs) and other endocapsular support devices have been important management options for patients with significant zonulopathy. Hara et al1 and Nagamato and Bissen-Miyajima2 introduced the first endocapsular devices, bu...

Selecting the best set of ads is critical for advertisers for a given set of keywords, which involves the composition of ads from millions of candidates. While click through rates (CTRs) are important, there could be high correlation among different ads, therefore the set of ads with top CTRs does not necessarily maximize the number of clicks. Greedy algorithm[1] has been a standard and straigh...

BACKGROUND Neurotoxic effects are known to occur with inhalation of manganese particulates, but very few data are available on exposure to Mn in water. We undertook a pilot study in a community in Quebec (Canada) where naturally occurring high Mn levels were present in the public water system. Our objective was to test the hypothesis that greater exposure to Mn via drinking water would be refle...
