Chemical and immunochemical measurement of total iron-binding capacity compared. (1/1676)

Radiometric, colorimetric, and two immunochemical methods for measuring total iron-binding capacity are compared. We evaluated the procedures on the basis of precision, applicability to a pediatric population, and accuracy as assessed by analytical recovery of purified transferrin. The immunoephelometric assay for transferrin provides significant advantages over the other methods examined.  (+info)

Improved antibody detection by the use of range expansion and longer filter wavelength in a low ionic strength-protamine sulphate Auto-Analyzer system. (2/1676)

Range expansion, achieved by insertion of a variable resistance between the colorimeter and the recorder together with the use of 550 nm colorimeter filters, has resulted in markedly improved sensitivity for antibody detection, and improved sample identification, in a low ionic strength-protamine sulphate (LISPS) system. Range expansion also permits a lower concentration of red cells to be used, thus economizing on fully typed cells. Glycerol stored frozen cells were found to be only slightly less sensitive than fresh cells in this system.  (+info)

Quantitative study of the variability of hepatic iron concentrations. (3/1676)

BACKGROUND: The hepatic iron concentration (HIC) is widely used in clinical practice and in research; however, data on the variability of HIC among biopsy sites are limited. One aim of the present study was to determine the variability of HIC within both healthy and cirrhotic livers. METHODS: Using colorimetric methods, we determined HIC in multiple large (microtome) and small (biopsy-sized) paraffin-embedded samples in 11 resected livers with end-stage cirrhosis. HIC was also measured in multiple fresh samples taken within 5 mm of each other ("local" samples) and taken at sites 3-5 cm apart ("remote" samples) from six livers with end-stage cirrhosis and two healthy autopsy livers. RESULTS: The within-organ SD of HIC was 13-1553 microg/g (CV, 3.6-55%) for microtome samples and 60-2851 microg/g (CV, 15-73%) for biopsy-sized samples. High variability of HIC was associated with mild to moderate iron overload, because the HIC SD increased with increasing mean HIC (P <0.002). Livers with mean HIC >1000 microg/g exhibited significant biological variability in HIC between sites separated by 3-5 cm (remote sites; P <0.05). The SD was larger for biopsy-sized samples than for microtome samples (P = 0.02). CONCLUSION: Ideally, multiple hepatic sites would be sampled to obtain a representative mean HIC.  (+info)

Nonenzymatic reduction of benzo(a)pyrene diol-epoxides to trihydroxypentahydrobenzo(a)pyrenes by reduced nicotinamide adenine dinucleotide phosphate. (4/1676)

The diol-epoxide r-7,t-8-dihydroxy-t-9,10-oxy-7,8,9,10-tetrahydrobenzo(a)pyrene is a potent mutagen and possibly the ultimate carcinogenic form of benzo(a)pyrene. A (7/8,9)-trihydroxy-7,8,9,10,10-pentahydrobenzo(a)pyrene is formed from the diol-epoxide r-7,t-8-dihydroxy-t-9,10-oxy-7,8,9,10-tetrahydroxybenzo(a)pyrene by reduction with reduced nicotinamide adenine dinucleotide phosphate. Its formation is linear with reduced nicotinamide adenine dinucleotide phosphate concentration and does not require the presence of enzyme. A (7,9/8)-trihydroxy-7,8,9,10,10-pentahydrobenzo(a)pyrene is similarly formed from the diol-epoxide r-7,t-8-dihydroxy-c-9,10-oxy-7,8,9,10-tetrahydrobenzo(a)pyrene by reduction with reduced nicotinamide adenine dinucleotide phosphate. The structures of the trihydroxypentahydrobenzo(a)pyrenes were established by their ultraviolet absorption and mass spectra and their reaction with potassium triacetylosmate.  (+info)

Stable thiobarbituric acid chromophore with dimethyl sulphoxide. Application to sialic acid assay in analytical de-O-acetylation. (5/1676)

With dimethyl sulphoxide instead of butanol in the thiobarbituric acid assay for sialic acid, a non-fading chromophore with lambdamax. = 549 nm was produced in a homogeneous solution, allowing dilution of the test mixture in case of high colour yield. This test adapted well to studies on alkaline de-O-acetylation. Bovine and rat submaxillary mucins, and rabbit Tamm-Horsfall urinary sialoproteins contain O-acetyl isomers of neuramine acid that are resistant to the thiobarbituric acid assay. Alkaline de-O-acetylation converted resistant O-acetylneuraminic acid into thiobarbituric acid-reactive sialic acid, and such conversion paralleled de-O-acetylation as measured by the ferric hydroxamate method. The colour increment was similar when the alkaline treatment of bovine submaxillary mucin either preceded or followed the acid hydrolysis. Only alkaline preptreatment was effective with rat submaxillary mucin. By selecting optimal conditions for alkaline de-O-acetylation, O-acetyl isomers can be accurately assessed by the thiobarbituric acid assay.  (+info)

A colorimetric technique for detecting trichothecenes and assessing relative potencies. (6/1676)

We tested a novel colorimetric toxicity test, based on inhibition of beta-galactosidase activity in the yeast Kluyveromyces marxianus, for sensitivity to a range of mycotoxins. A variety of trichothecene mycotoxins could be detected. The order of toxicity established with this bioassay was verrucarin A > roridin A > T-2 toxin > diacetoxyscirpenol > HT-2 toxin > acetyl T-2 toxin > neosolaniol > fusarenon X > T-2 triol > scirpentriol > nivalenol > deoxynivalenol > T-2 tetraol. The sensitivity of detection was high, with the most potent trichothecene tested, verrucarin A, having a 50% effective concentration (concentration of toxin causing 50% inhibition) of 2 ng/ml. Other mycotoxins (cyclopiazonic acid, fumonisin B1, ochratoxin A, patulin, sterigmatocystin, tenuazonic acid, and zearalenone) could not be detected at up to 10 micrograms/ml, nor could aflatoxins B1 and M1 be detected at concentrations up to 25 micrograms/ml. This test should be useful for trichothecene detection and for studies of relevant interactions-both between trichothecenes themselves and between trichothecenes and other food constituents.  (+info)

The association between occupational lead exposure and serum cholesterol and lipoprotein levels. (7/1676)

OBJECTIVES: This study sought to clarify the possible associations between blood lead level and serum cholesterol and lipoprotein levels in subjects occupationally exposed to lead. METHODS: Levels of blood lead, serum total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein cholesterol, and triglycerides in 56 male industrial employees who were exposed to lead were compared with those in 87 unexposed employees. RESULTS: Mean blood lead levels were 42.3 (+/- 14.9) micrograms/dL in the exposed group and 2.7 (+/- 3.6) micrograms/dL in the nonexposed group. The exposed subjects had higher mean levels of total cholesterol and HDL cholesterol. CONCLUSIONS: Blood lead levels are positively associated with total and HDL cholesterol.  (+info)

The MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay is a fast and reliable method for colorimetric determination of fungal cell densities. (8/1676)

The entomopathogenic fungus Neozygites parvispora (Entomophthorales: Zygomycetes) grows in vitro as irregularly rod-shaped hyphal bodies in a complex medium. In order to simplify the medium composition and determine growth-promoting compounds for the cultivation of this fungus, we were looking for a rapid and quantitative method to estimate the number of living cells in small volumes of liquid culture. A colorimetric method for the determination of cell densities using MTT [3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide] proved to be more accurate and timesaving than conventional hemocytometer counting.  (+info)

Introduction. \\wss1caterham\nievettha.r$\My Documents\Applied Science\2.jpg Colorimeter Background Information - Colorimeter A colorimeter is an apparatus for measuring heat quantities. A colorimeter is calibrated using known concentrations of a coloured solution. The part of the light is absorbed when light is passed through a medium and as a result, there is a decrease in how much of the light reflected by the medium. A colorimeter measures the change that is occurred so that people that are using the colorimeter can analyse the concentration of a particular substance in that medium. The more concentrated the solution is, the more light that will be absorbed. Colorimeter has three main parts which are the light source, a cuvette and a photo resistor. The cuvette holds the solution and the colorimeter is equipped with coloured filters to produce coloured light. The light that is transmitted by the solution in the cuvette is detected by a photo cell and it produces signal such as the ...
In addition to enough contact time, adequate tidal volume is necessary to create a recognizable color change in colorimetric ETCO2 detectors. A device with a larger dead space volume may require larger tidal volumes to show a color change than one with a smaller dead space. Small volumes may get washed out in the dead space of the device, producing a false negative result.1,11 The Neo-StatCO2 is the first colorimetric detector labeled for infants ,1 kg. The product literature from the manufacturer on the resistance of this new detector is limited to 5 L/min. We compared the Neo-StatCO2 with other colorimetric ETCO2 devices in the flow range in which they are most widely utilized, 6-10 L/min. To our knowledge, there are no prior publications validating the manufacturers specifications (Fig. 1). The dead space has been decreased and the resistance to flow has increased in the Neo-StatCO2 compared with the Mini StatCO2. There are no studies demonstrating that these design changes have improved the ...
The readings by themselves are typically not as useful as their tristimulus values, which can be converted into chromaticity co-ordinates and manipulated through color space transformations. For this purpose, a spectrocolorimeter may be used. A spectrocolorimeter is simply a spectrophotometer that can estimate tristimulus values by numerical integration (of the color matching functions inner product with the illuminants spectral power distribution).[5] One benefit of spectrocolorimeters over tristimulus colorimeters is that they do not have optical filters, which are subject to manufacturing variance, and have a fixed spectral transmittance curve-until they age.[6] On the other hand, tristimulus colorimeters are purpose-built, cheaper, and easier to use.[7]. The CIE (International Commission on Illumination) recommends using measurement intervals under 5 nm, even for smooth spectra.[4] Sparser measurements fail to accurately characterize spiky emission spectra, such as that of the red phosphor ...
Operator-independent assessment of skin blanching is important in the development and evaluation of topically applied steroids. Spectroscopic instruments based on hand-held probes, however, include elements of operator dependence such as difference in applied pressure and probe misalignment, while laser Doppler-based methods are better suited for demonstration of skin vasodilatation than for vasoconstriction.. To demonstrate the potential of the emerging technology of Tissue Viability Imaging (TiVi) in the objective and operator-independent assessment of skin blanching.. The WheelsBridge TiVi600 Tissue Viability Imager was used for quantification of human skin blanching with the Minolta chromameter CR 200 as an independent colorimeter reference method.

A highly selective and sensitive spectrophotometric determination of cobalt (II) was developed. 7-Nitroso-8-hydroxyquinoline-5-sulfonic acid sodium salt was used as the chromogenic reagent for color development. Although other metals form colored chelates with the ligand, it was possible to develop a selective method using McIlvaines pH 8 citric acid-phosphate buffer. Under these conditions, iron(II), iron (III), copper (II), zinc (II), and manganese (II), minerals likely to be compounded with cobalt (II) in geriatric formulations, do not interfere with the precision of the method or the color development. Calcium (II) and magnesium (II) do not form colored chelates with the used ligand. Hormones, vitamins, and additives likely to be present along with the cobalt ion in pharmaceutical formulations do not interfere. The sensitivity is 0.37 mug of cobalt (II)/ml of sample solution. ...

US scientists have developed and tested a prototype breath test to detect lung cancer. The results of the test is published in the international journal of respiratory medicine Thorax.. In tests, the colour testing device, which is about the size of a coin and is not expensive, had a 75 per cent success rate in detecting people with cancer.. It can also detect people with early stages of lung cancer.. However, in testing the device also showed false positives - it picked out people without lung cancer.. Using a technique called a colorimetric sensor array, the test picks up the chemical fingerprint of the breath of people with lung cancer.. Lung cancer tumours, like other cancers, produce volatile organic compounds (VOCs) that are different to normal cells. And because the tumours are in the lungs, the breath is likely to contain signs of these abnormal compounds. This means the potential for a lung cancer fingerprint in the breath is a viable method for detection. ...

The presence of Escherichia coli (E. coli) in food and drinking water is a chronic problem worldwide. Protecting food against bacterial contamination and rapid diagnosis of infection require simple and rapid assays for detection of bacterial pathogens, including E. coli O157:H7. Here we report a rapid and novel colorimetric method for detecting E. coli O157:H7. This colorimetric method is based on the catalytic oxidation of the peroxidase substrate 3,3,5,5-tetramethylbenzidine by hydrogen peroxide using 4-mercaptophenylboronic acid-functioned [email protected] nanoparticles adsorbed on the surface of E. coli O157:H7. The assay showed excellent sensitivity both with the naked eye and based on absorbance measurements. The absorbance at 652 nm was proportional to the concentration of E. coli O157:H7 ranging from 7 to 6 × 10(6) cfu mL(-1) with a limit of detection of 7 cfu mL(-1). The total detection time was less than 40 min.

Methods The antitumor effect of C. crepidioides was evaluated in S-180-cell-bearing mice. Cell growth was assessed using a colorimetric assay. Nitrite and nitrate levels were measured by colorimetry. The expression levels of inducible NO synthase (iNOS) in murine RAW264.7 macrophages was assessed by reverse transcriptase-polymerase chain reaction. Activation of iNOS promoter was detected by reporter gene. Activation of nuclear factor-κB (NF-κB) was evaluated by electrophoretic mobility shift assay. The role of NF-κB signaling was analyzed using inhibitors of NF-κB and dominant-negative mutants, and Western blot analysis ...

Color definition and data exchange continue to be dominant themes in both the US and international graphic arts standards activity. However, there is a growing understanding of the role that metrology and printing process definition play in helping define stable process conditions to which color characterization data can be related. Standards have already been published that define the requirements for color measurement and computation, scanner input characterization targets, four-color output characterization data sets, and graphic arts applications of densitometry. Work continues on standards relating to ink testing and ink color specifications. The numerical specifications of SWOP proof printing have been captured in ANSI standard CGATS.6-1995. Work has been completed, and Technical Report ANSI CGATS TR 001-1995 has been published, that relates the colorimetry of the printed sheet to the CMYK input for press proofing meeting SWOP and CGATS.6 specifications. Work is ongoing to provide similar ...
This paper introduces the principle and configuration of an auto urine analysis system. The system employs an ARM-LPC2214 as CPU and a color linear-CCD as sensor. A CPLD is used to produce pulses for the CCD and for other circuits in the system. The CPLD is programmed through Verilog HDL language. The sick is determined according to the color change of test strips. Principle of color test circuit and design of software for identifying color data are also described. The software uses the principle of CIE Colorimetry to identify the color. Experiments show that test speed is fast and the result is precise. This system is suitable for the situations in which a large number of samples are to be treated ...
Improvements in non-invasive detection methods for glucose and other constituents of interest in a sample have been developed. The apparatus and methods of the invention provide an analog of color perception of human vision, preferably in the near infrared region, replacing spectrophotometers and narrow band sources used in other non-invasive near infrared detection methods. A plurality of detector units are used, each covering a broad and overlapping region of the detected spectrum, paralleling color perception and colorimetry. The improvements are primarily concerned with improving the signal-to-background (or noise) ratio such that the data stream is improved. These improvements use congruent sampling, comparison of different data streams from different sample portions or filter sets, using an interrogation system with sufficient speed to allow testing of arterial blood, and using a filter with a spectral structure. In some circumstances, a neural net is used for analysis, allowing the system to

This work presents the development of bioassays and biosensors for the detection of insecticides widely used in the treatment of olive trees. The systems are based on the covalent immobilisation of acetylcholinesterase on magnetic microbeads using either colorimetry or amperometry as detection technique. The magnetic beads were immobilised on screen-printed electrodes or microtitration plates and tested using standard solutions and real samples. The developed devices showed good analytical performances with limits of detection much lower than the maximum residue limit tolerated by international regulations, as well as a good reproducibility and stability.
