DEAR SIRS-Two recent articles by Klein and Millwood (1952, 1953) have prompted me to make a few comments on some eight cases of corneal ulceration with the Ps. pyocyanea which I have seen since an article by Bignell appeared in 1951. Of the eight cases, six had a simple corneal foreign body removed, and in these the cornea became infiltrated round the former site of the foreign body within 48 h...

introduction: methodologically correct assessment of patient satisfaction (ps) plays a crucial role for quality-improvement purposes. evaluation of iranian literature on emergency department’s ps resulted in an emerging need for developing a new instrument with satisfactory psychometric properties. the present study, aimed to develop and initially validate a scale to measure ps in emergency dep...

conclusions it seems that severe pah aggravates the rv function more severely. results significant tricuspid regurgitation was more prevalent in the pah group than in the ps group (61% vs. 18.5%; p < 0.001). the abnormalities in the rv myocardial performance index, rv areas, and rv fractional area change were significantly more robust in the pah group (all ps < 0.05) despite the higher net rv s...

The fluorescence decay kinetics of photosynthetic mutants of Chlamydornonas reinhardii which lack photosystem 11 (PS 11), photosystem I (PS I), and both PS I1 and PS I have been measured. The PS I1 mutant strain 8-36C exhibits fluorescence decay lifetime components of 53, 424 and 2197 ps. The fluorescence decay of a PS I mutant strain 12-7 contains two major fluorescence decay components with l...

BACKGROUND Repeated immunizations with polysaccharide (PS) vaccines cause hyporesponsiveness through undefined mechanisms. We assessed the effects of a PS booster on immune responses, frequency, and survival of PS-specific B-cell subpopulations in spleen and bone marrow. METHODS Neonatal mice were primed with meningococcus serotype C (MenC) conjugate MenC-CRM(197)+CpG1826, boosted with MenC-C...
