Purpose. This study examines the effects of fundus fluorescein angiography (FFA) procedure on ocular pulse amplitude (OPA) and intraocular pressure (IOP). Materials and Methods. Sixty eyes of 30 nonproliferative diabetic retinopathy patients (15 males, 15 females) were included in this cross-sectional case series. IOP and OPA were measured with the Pascal dynamic contour tonometer before and af...

We report calculations of one and two photon absorption (OPA and TPA, respectively) spectra of the green fluorescent protein (GFP) chromophore using the doubleharmonic parallel-mode approximation and including explicit dependence of the electronic transition moments on nuclear geometry. The non-Condon effects are found to be more significant for TPA resulting in a different shape of the spectra...

Neisseria meningitidis causes half a million cases of septicemia and meningitis globally each year. The opacity (Opa) integral outer membrane proteins from N. meningitidis are polymorphic and highly immunogenic. Particular combinations of Opa proteins are associated with the hyperinvasive meningococcal lineages that have caused the majority of serogroup B and C meningococcal disease in industri...

BACKGROUND The behavioural and socio-cultural processes underlying the association between socio-economic position (SEP) and body mass index (BMI) remain unclear. Occupational physical activity (OPA) is one plausible explanatory variable that has not been previously considered. OBJECTIVES 1) To examine the association between OPA and BMI, and 2) to examine whether OPA mediates the SEP-BMI ass...

Unambiguous evidence is presented that the chloride ions play a dual role in formation of micrometre thick film polymerized [Cu-Cl-MBI] n . This occurs when copper exposed to 3 wt.% NaCl solution containing 1 mM mixture inhibitors 2-mercaptobenzimidazole, MBI, and octylphosphonic acid, OPA, molar ratio MBI:OPA 9:1. The act simultaneously as promoter [Cu–MBI] /[Cu–Cl–MBI] reactant incorporated f...

The mechanisms of the mycobactericidal action of ortho-phthalaldehyde (OPA), glutaraldehyde (GTA) and chlorhexidine diacetate (CHA) were investigated using mycobacterial spheroplasts of two reference strains, Mycobacterium chelonae NCTC 946, Mycobacterium abscessus NCTC 10882 and two GTA-resistant strains, M. chelonae Epping and M. chelonae Harefield. Transmission electron microscopy of the sph...

The Ca(2+)-ATPase in the sarcoplasmic reticulum of skeletal muscle reacts with o-phthalaldehyde (OPA) to form a fluorescent isoindole product. The stoichiometry of labelling of the ATPase is 9 nmol of isoindole/mg of ATPase, corresponding to a 1:1 molar ratio of isoindole: ATPase. There is no evidence for any intermolecular cross-linking. Isoindole formation is faster in the presence of methyla...

the House Ways and Means Committee on September 23. He explained that this would allow the hospitals to further stretch their limited resources and relieve them of the burden of carrying two separate inventories and pricing structures for inpatient and outpatient drugs. Theoretically, the Ways and Means Committee, in conjunction with Energy and Commerce and Senate Finance, could initiate author...
