Confocal fluorescence recovery after photobleaching (FRAP) is today the prevalent tool when studying the diffusional and kinetic properties of proteins in living cells. Obtaining quantitative data for diffusion coefficients via FRAP, however, is challenged by the fact that both bleaching and scanning take a finite time. Starting from an experimental case, it is shown by means of computer simula...

Two-dimensional fluid phase connectivity is examined in mixed bilayers of dimyristoyl phosphatidylcholine and dipalmitoyl phosphatidylcholine as a function of composition and temperature at constant pressure using fluorescence recovery after photobleaching (FRAP). These isomorphous phospholipid mixtures exhibit nearly ideal mixing behavior. Dilauroyl phosphatidylethanolamine covalently linked t...

The American “high school movement” of the early 20th century resulted in a dramatic rise in high school graduation rates, a trend that continued into the middle of the century interrupted only by World War II. Previous work has characterized the pre-World War II transformation of secondary education, but less attention has been focused on the continued increased in educational attainment after...

PURPOSE To compare the rates of rapid posterior capsule opacification (PCO) formation in the first 3 months following femtosecond laser-assisted cataract surgery (FLACS) to manual anterior capsulorhexis. METHODS Retrospective review of 29 cases of FLACS, comparing the rates of PCO in the first 3 months following surgery to 50 consecutive cases of manual anterior capsulorhexis. RESULTS Seven...

* Prepared in the Division of Finance and Economic Studies, Bureau of Research and Statistics. Use of variable rates of social insurance contributions in preventing a decline in consumer purchasing power and hence in employment is one of the methods advocated by the British Government in its proposed plan for maintaining high employment after the war. The following article outlines briefly that...

PURPOSE To investigate the ability of an open capsule device to prevent posterior capsule opacification. METHODS A total of 40 eyes of 20 New Zealand white rabbits were randomly divided into six similar groups of 6 to 7 eyes each. After crystalline lens evacuation, one control group (group A) was implanted with a hydrophilic acrylic intraocular lens and no device, and another control group (g...

Posterior capsulorhexis with optic capture was originally described by Gimbel and DeBroff [4] to maintain a clear visual axis after pediatric cataract surgery. This technique involves capturing the IOL optic through a primary posterior continuous curvilinear capsulorhexis (PCCC), while the haptics remain within the capsular bag (Figure 1). Studies have demonstrated this to be a valuable techniq...

Clinical guidelines often make recommendations on the use of diagnostic tests. Compared with sensitivity and specificity, the use of pre- and post-test probabilities allows a more explicit and rational selection and interpretation of diagnostic tests. Ideally, clinical guidelines relating to diagnosis should routinely incorporate this information to enhance individualised decision making. We re...

Members of the cast for the Gay Nineties Show, free outdoor attraction to be staged in conjunction with the Owl Festival, benefit carnival sponsored by the Episcopal Diocese of Texas at House April 18-19, were stepping up rehearsals to three a we§k Thursday as theproduction deadline neared. Mary Virginia Stevens will have the singing lead in the Gay Nineties attraction, supported by a sister ac...
