Journal Article 2016; 37(Suppl 1): 17-24 PubMed PMID: 28263526 Citation Keywords: Animals, Biological Assay:methods, Environmental Monitoring, Fishes, Toxicity Tests:methods, Waste Water:toxicity, Water Pollutants, Chemical:toxicity,. : Wastewater, especially containing hospital effluents, exhibits high chemical complexity and specificity since it includes various chemicals, biocides, pharmaceuticals, surfactants, radionuclides, disinfectants and pathogens. Biological tests provide true evidence of the wastewater quality and unlike chemical analytical tests show comprehensive pollution effects on the environment and human health. Normalized conventional bioassays are not sensitive enough for ecotoxicological evaluation of wastewater and there is a great need for the development of suitable sensitive bioassays in order to characterize properly the residual toxicity of treated effluents. Provisions of binding EU legislation regarding protection of animals used for scientific purposes and ...
Plasma samples obtained from patients receiving a 24-h continuous infusion of human recombinant (hr)TNF or a combination of two overlapping, 24-h continuous infusions of hrIFN-gamma and hrTNF were analyzed for IL-6 in a sensitive bioassay. A transient appearance of circulating IL-6 was observed with peak levels between 3 and 6 h after the start of the hrTNF infusion. These peak levels correlated quite well with the dose of hrTNF administered (r = 0.86; p less than 0.001). The maximal value observed was 27.5 ng/ml IL-6 in a sample of a patient receiving 545 micrograms/m2 hrTNF. The combination of hrIFN-gamma (200 micrograms/m2) and hrTNF in the infusions resulted in higher IL-6 levels than a comparable dose of hrTNF alone. A maximal value of 23.5 ng/ml IL-6 was observed in a patient receiving 205 micrograms/m2 hrTNF. No IL-6 was found in the plasma of patients during the 12-h infusion with hrIFN-gamma alone, except for two borderline samples. ...

TY - JOUR. T1 - Soluble CD141-152 confers responsiveness to both lipoarabinomannan and lipopolysaccharide in a novel HL-60 cell bioassay. AU - Yu, Weiming. AU - Soprana, Elisa. AU - Cosentino, Giovanna. AU - Volta, Manuela. AU - Lichenstein, Henri S.. AU - Viale, Giovanna. AU - Vercelli, Donata. PY - 1998/10/15. Y1 - 1998/10/15. N2 - CD14 is a pattern recognition receptor involved in the interaction with multiple ligands, including LPS from Gram-negative bacteria and lipoarabinomannan (LAM) from mycobacteria. While the interactions between LPS and soluble CD14 (sCD14) have been analyzed in detail, LAM/CD14 interactions remain uncharacterized due to the lack of suitable functional assays. We describe herein a novel bioassay for the analysis of CD14/ligand interactions. CD14-negative myeloid HL-60 cells up-regulate endogenous CD14 gene expression when stimulated with LPS in the presence of recombinant soluble CD141-348. Using the HL-60 bioassay, we showed that sCD141- 348 confers responsiveness ...

C55 High throughput screening technologies have revolutionized the manner in which potential therapeutics are identified. One casualty of the move to high throughput screening technologies has been the widespread disappearance of natural product extracts from pharmaceutical screening programs. Though they are the source of lead compounds for ~65% of anticancer and antimicrobial drugs approved by the FDA between 1981-2002, natural products have often been excluded from modern screening programs. This is due, at least in part, to the inherent difficulties in testing complex extract mixtures, which often contain nuisance compounds, in modern bioassay systems. Here we present a novel electrochemiluminescent assay system that is suitable for testing natural product extracts in high throughput screening systems. To demonstrate its utility, we have developed a screen for inhibition of E3 (ubiquitin ligase) activity utilizing the cancer-relevant molecular target MDM2. Additional screens for inhibition ...

Hi For the last 8 months Ive been working on an in vitro bioassay for FSH. However, I have been struggling with a lack of sensativity when dealing with serum samples which are typically around the 2 ng/ml region. The assay involves incubating sertoli cells from the testes of 7-10 day old rats in the presence of FSH. The presence of FSH then causes a dose-dependent increase in aromatase activity when adrostendione is converted to estradiol which can be measured to determine the concentration of FSH. If anyone out there is familiar with this assay and can help me to increase the sensativity (by decreasing the variability) then please e-mail me Wayne Young Youngwa at agresearch.cri.nz AgResearch New Zealand ...

A method for performing time resolved homogeneous assays using a long-lifetime luminescent dye as a donor. A reaction well containing a sample portion, donor reagent, and acceptor reagent and a matrix well containing a sample portion and donor reagent are excited and the resulting emission from each is measured at a single wavelength associated with the acceptor. The measurement obtained from the matrix well is used to provide a correction for the measurement obtained from the reaction well. The sample may be a biological fluid such as an oral fluid.
In general, all constituents of a multi-component compound are not equally important for the process in hand. If we restrict ourselves to some sort of biological assay or property measure such as logD or pKa, then these are easily understood as reflecting the presence of a parent molecule. Data such as aD reflect the presence of isomeric parent molecule. Note that neither of these parent molecules have an independent existence as a physical entity, in the Daylight sense they are identifiers or names, about which, data exist. Data such as melting point are clearly about a particular sample, as are the experimental results of both physicochemical and biological assays. A version molecule structure may also have been assigned to this sample perhaps a salt or solvate or even a impure isomer.. Calculated data such as cLogP are about the parent molecule, whereas a rubicon structure is a datum about the isomeric parent. An x-ray structure on the other hand is a datum about the sample, and is related to ...
Secondly we were interested in the amount and distribution of PrPSc at 24 mpi, since the extent of this accumulation varied at earlier time points with peaks at 8 and in particular 12 mpi and lows at 16 mpi respectively [10]. However, these earlier studies did also suggest a higher amount in animals at 24 mpi suggesting an undulant pattern of about 12 months. This finding is now supported by the bioassay results, as three out of the four cattle from the 24 mpi group showed levels and distribution of infectivity comparable to the peaks seen at 12 mpi. However it has to be bear in mind that only four animals per time point were investigated here and in earlier studies and that the variations between individuals are very high [10,14]. This is reflected in the present study by variable detection rates in different animals of the 24 mpi group and might explain the differences seen in infectivity levels reported for ileal samples by several authors before [6,9-11,15]. In summary, data presented here ...

The effects of many chemicals on cellular processes are governed by their ability to enter the cell, which is in turn a function of the composition of the cells external environment. To examine this relationship, the effect of serum in cell culture medium on the bioavailability of cytochrome P450 1A (CYP1A)-inducing compounds was determined in PLHC-1 (Poeciliopsis lucida hepatocellular carcinoma) cells. The presence of 10% calf serum in the medium increased the EC50 (effective concentration to achieve 50% maximal response) for induction of ethoxyresorufin O-deethylase (EROD) activity by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) 20-fold as compared to treatment in serum-free medium. Measurement of [3H]TCDD uptake and Ah receptor binding indicated that the apparent difference in potencies was a result of decreased bioavailability in the presence of serum, effectively reducing the concentration of TCDD within the cells. Induction of EROD and CYP1A protein in response to treatment with each of ...

Several of the pressing scientific challenges in the filed of environmental toxicology are to understand the basic mechanisms of chemically-induced toxic substances and of the design, interpretation, and extrapolation of data from non-human bioassay systems to the human situation. The objective is to offer a new paradigm, namely the idea that cytotoxic and epigenetic effects of chemicals can contribute to many toxic endpoints in human beings. We will speculate that the disruption of calcium homeostasis by a wide variety of chemicals and the conditions of their use might provide an unification of mechanisms leading to either cytotoxicity or epigenetic changes. Depending on the conditions, the effects of this disruption, a pleiotropy of diseases might result, namely, embryotoxicity, teratogenesis, tumor promotion, immune modulation, neurotoxicity, and preproductive dysfunction. In summary, there are at least three biological endpoints at the cell level which chemicals can influence - mutations, cell death

Three pressor amines, namely, epinephrine, 3,4-dihydroxyphenethyl-methylamine and 3,4-dihydroxyphenethyldimethylamine were tested for relative potencies by an increasing dose method, and the data were studied to determine when linear relationships might be assumed. The following conclusions may be drawn:. 1. The Weber-Fechner law may be said to hold for restricted ranges of our data but not for the data as a whole.. 2. The application of a progressively increasing dose method to the biological assay of epinephrine may be an improvement upon the U.S.P.XI procedure.. 3. Expressing relative pressor potencies on the basis of doses required to elicit a specific response may not convey a true picture when the characteristic slopes of the logarithmic dose-response curves of two compounds are not identical.. 4. When the logarithmic curves of compounds being compared with epinephrine are dissimilar, it may indicate the presence of qualitative differences in action.. ...
