The color of prints is mainly determined by the light absorption of the inks deposited on top of paper. In order to predict the reflectance spectrum of prints, we use a spectral prediction model in which each ink is characterized by its spectral transmittance. In the present paper, we consider two classical reflectance prediction models: the Clapper-Yule model and the Williams-Clapper model. Th...

background: welding emits harmful rays to the eyes. we evaluate and compare the uv, blue light and ir transmittance characteristics of some currently available welding safety protectors with ansi z87.1 criteria. materials and methods: three type of welding safety protectors (three of each type) have been evaluated for spectral transmittance. one-sample t-test was performed to establish is there...

BACKGROUND Engineered nanoparticles (NPs) can induce platelet activation and aggregation, but the mechanisms underlying these interactions are not well understood. This could be due in part to use of devices that study platelet function under quasi-static conditions with low sensitivity to measure platelet microaggregation. Therefore, in this study we investigated the pharmacological pathways a...

An in vitro test for the development of corneal opacity in response ocular irritants was first proposed by Muir (1984). This test required the clamping of a bovine cornea between two chambers filled with physiologic saline and measuring the transmittance of white light through the cornea using the voltage output of a photocell. This was followed by exposure of the epithelial surface of the corn...

BACKGROUND Aspirin (ASA) reduces adverse events in coronary artery disease (CAD) patients by inhibiting platelets. Some CAD patients have high platelet reactivity (HPR) despite ASA therapy and these individuals have increased risk of adverse events. OBJECTIVE The purpose of this study was to determine the prevalence of HPR in ASA-treated patients referred for coronary angiography and to asses...

OBJECTIVES Controversy has been prompted based on drug interaction between proton pump inhibitors (PPIs) and aspirin/clopidogrel leading to weakened effects. However, whether such interaction was drug-specific or class effect remains controversial. This study predicted the impact of esomeprazole and rabeprazole on efficacy of dual antiplatelet therapy (DAPT). METHODS This study, involving 150...

BACKGROUND AND OBJECTIVES Triple anti-platelet therapy may produce more potent inhibition of platelet aggregation in patients undergoing coronary stent implantation. We tested whether this effect could be maintained in diabetic patients, where platelet reactivity is increased and the risk of stent thrombosis is higher. SUBJECTS AND METHODS Fifty five type 2 diabetic patients who had undergone...

To assess platelet function profiles in diabetic and nondiabetic patients on aspirin and clopidogrel therapy, two patient populations were included to investigate the 1) acute effects of a 300-mg clopidogrel loading dose (group 1, n = 52) and 2) long-term effects of clopidogrel (group 2, n = 120) on platelet function in diabetic compared with nondiabetic patients already on aspirin treatment. P...

This paper focuses on application of co-axial electrospinning technique to the development of nanofiber reinforced transparent composites. Investigations have been done on fabrication and functionalization of the transparent composites with improved mechanical properties, thermal properties and shielding ability for ultraviolet radiations. In the fabrication, PMMA, a polymer with excellent visi...
