A 34-year-old female with Usher syndrome, but no family history of similar illness, presented with complaints of vision reduction, redness, and photophobia. Biomicroscopic examination showed mildly injected conjunctivae bilateral, small, round keratic precipitates; bilateral +2 cells with no flare reaction in the anterior chamber; and bilateral posterior subcapsular cataracts. No associated pos...

This study proposed a constitutive equation to predict the change in yield strength according behavior of β″ metastable precipitates, which have profound effect on among materials precipitated during T6 heat treatment Al-Mg-Si alloy. The precipitate is phase before it becomes β (Mg2Si) precipitate, and distributed form nano-scale rods aluminum alloy matrix. Existing precipitation strengthening ...

above the line of contact of the two fluids, a layer of precipitation quite distinct from the precipitate of albumen produced by the nitric acid. This is distinguished from the precipitate of urates which sometimes occurs by not disappearing when heated. When observed at all it has been described as mucin precipitated by the acid. Dr Maguire has recently referred to this reaction in an article ...

The effects of ammonium (NH4) and magnesium (Mg) on the precipitation of phosphorus in artificial wastewater by an air-cathode single-chamber microbial fuel cell were investigated. When both NH4 and Mg were added to the wastewater, phosphorus was precipitated as struvite. Almost no precipitation occurred with the addition of only NH4, while phosphorus was precipitated as cattiite with the addit...

Diphtheria toxoid-antitoxin precipitates formed in antitoxin excess can prepare guinea pigs, rats, and rabbits for a secondary type of antitoxin response. Priming may occur without the development of detectable serum antibody. In rats, toxoid-antitoxin precipitates are more efficient than "free" toxoid in priming, whereas in guinea pigs, the magnitude of the anamnestic response varies with the ...

PURPOSE To elucidate, in light of reports of complications associated with intraarterial infusion of papaverine hydrochloride, the known propensity of papaverine hydrochloride to form precipitate in combination with other solutions or pharmaceuticals. METHODS Initially simulating a situation experienced during an intraarterial papaverine infusion for cerebral vasospasm, we mixed various conce...
