Does malaoxon play a role in the geno- and cytotoxic effects of malathion on human choriocarcinoma cells?

This investigation was undertaken to elucidate whether the active metabolite of malathion, malaoxon, has any role in exerting cyto- and genotoxic effects for human choriocarcinoma (JAR) cell line which is an acceptable model for human placental cells. Gas chromatography-mass spectrometry (GC-MS) analysis were separately performed on the cell compartment and supernatant cell culture medium after subjecting the cell line to different malathion concentrations (10-400 μg/mL) and for various incubation periods (0.5 to 24 hours).

[Can the decrease of blood alcohol level be accelerated? Results of a clinical study].

The purpose of this study was to examine the effect of Guardian Angel powder (GA) on the blood alcohol level. According to the experimental protocol, two sets of measurement were performed: modeling the eating and drinking habit of a typical family or social meeting, alcohol containing drinks corresponding to 70 g of pure alcohol and copious amount of food were consumed first without GA powder, then with GA powder. In the latter case GA powder was dissolved in water and one dose was taken before eating, the other one was consumed during eating.

Structural basis of the cofactor function of denatured albumin in plasminogen activation by tissue-type plasminogen activator.

Certain denatured proteins function as cofactors in the activation of plasminogen by tissue-type plasminogen activator. The present study approached the structural requirements for the cofactor activity of a model protein (human serum albumin). Heat denaturation of 100-230 microM albumin (80 degrees C and 60-90 min) reproducibly yielded aggregates with radius in the range of 10-150 nm.

Maximum-entropy decomposition of fluorescence correlation spectroscopy data: application to liposome-human serum albumin association.

Fluorescence correlation spectroscopy was used to measure the diffusion behavior of a mixture of DMPC or DMPC/DMPG liposomes with human serum albumin (HSA) and mesoporphyrin (MP), which was used as the fluorescent label for liposomes and HSA as well. For decomposing the fluorescence intensity autocorrelation function (ACF) into components corresponding to a liposome population, HSA and MP, we used a maximum entropy procedure that computes a distribution of diffusion times consistent with the ACF data. We found that a simple parametric non-linear fit with a discrete set of decay components did not converge to a stable parameter set.
