This study proposes a vision model for individual colorimetric observers. The proposed model can be beneficial in many color-critical applications such as color grading and soft proofing to assess ranges of color matches instead of a single average match. We extended the CIE 2006 physiological observer by adding eight additional physiological parameters to model individual color-normal observer...

In the past few years there has been renewed interest in the study of serum cholinesterase in various disease states, particularly those affecting the liver. Recently, a colorimetric method for the determination of this enzyme in the serum was reported by Ravin, Tsou, and Seligman (1). Their method, simple to perform, is as accurate as the gastrometric technique and more specific than the elect...

Esteban Gonzalez Burchard and colleagues explore how making medical research more diverse would aid not only social justice but scientific quality and clinical effectiveness, too.

The cytotoxicity of the biomaterials is a key issue that should be addressed prior to pre-clinical applications. This study was designed to evaluate and compare the cytotoxixity of two forms of bioactive glasses:nanopowder and micropowder. Human HGF1-PI53 gingival fibroblast cells were used to evaluate the cytotoxicity of 0.5, 1, 1.5, 2, 5, 10, 15 and 20 mg/ mL concentrations of the two bioacti...

Talang Queenfish (Scomberoides commersonnianuus) is relatively inexpensive fish with low consumption in Fars Province, South of Iran. In this research which was done in 2011, minced fish sausages were produced from mince and surimi of this species and some physicochemical attributes of the products were investigated during 60 days of cold storage at 4 °C. According to the results, free fatty ac...

OBJECTIVE To incorporate the first polymerase chain reaction (PCR) assay for Calymmatobacterium granulomatis into a colorimetric detection system for use in routine diagnostic laboratories. METHODS A capture oligonucleotide specific for the Klebsiella phoE gene was covalently linked to tosyl activated magnetic beads. Biotinylated phoE PCR products obtained from 14 positive specimens from pati...

In the context of print quality and process control colorimetric parameters and tolerance values are clearly defined. Using more than one color measurement instrument measuring the same color wedge can produce clearly different results due to random and systematic errors of the instruments. In certain situations where one instrument gives values which are just inside the given tolerances and an...

Various chemicals can be added to urine specimens collected for drug analysis to abnormally elevate ionic concentrations and/or interfere with either immunoassay urine drug-screening procedures or gas chromatographic-mass spectrometric confirmation techniques. One such adulterant, "Urine Luck" (formula 5.3), has been identified in our previous research to contain potassium dichromate. Screening...

The excellent adaptability of Callithrix jacchus to life in captivity presents advantages comparison other nonhuman primates that are used experimental models for biomedical research, which explains the increasing scientific interest investigating anatomical characteristics this species. Owing relative scarcity publications on descriptive morphology heart C. jacchus, aim study was quantify pres...
