Sampling feasibility study of pathogenic organisms genetically modified or not in contained use activities
study use website Abstract: The aim of this study is to discern situations where sampling may be feasible and relevant. Both will be determined by the probability of subsisting biological risks arising ...
Membrane permeabilization and cellular death of Escherichia coli, Listeria monocytogenes and Saccharomyces cerevisiae as induced by high pressure carbon dioxide treatment.
treatment time (0-60 min) was examined. Loss of membrane integrity was measured as increased uptake of the fluorescent dye propidium iodide (PI) with spectrofluorometry, while cell inactivation was determined ...
A new statistical method for evaluating long-term analytical performance of laboratories applied to an external quality assessment scheme for flow cytometry.
RESULTS: The model was applied to the results obtained by 52 laboratories for CD4 %. From the 1340 data points, 35 were determined to be regression outliers. The second step revealed one regression line with ...
CYP3A5 and ABCB1 polymorphisms influence tacrolimus concentrations in peripheral blood mononuclear cells after renal transplantation.
determined at day 7 after transplantation and at steady state, and then compared with recipient genotypes. RESULTS & CONCLUSION: The ABCB1 1199G>A, 3435C>T and 2677G>T/A SNP s, appeared to reduce ...
Calibration of Human Coagulation Factor VII Concentrate Ph. Eur. BRP Batch 2
precision and homogeneity of fill, residual water content and stability. Thepotency of the candidate BRP (cBRP) was determined using chromogenic assays as required by the Ph. Eur. andin-house clotting assays ...
A proposed validation method for automated nucleic acid extraction and RT-qPCR analysis: an example using Bluetongue virus.
results, a triplex RT-qPCR was used which detects the target viral RNA, an internal and an external control. The methods to determine the validation parameters such as linearity, efficiency, analytical ...
Influenza A strain-dependent pathogenesis in fatal H1N1 and H5N1 subtype infections of mice.
mice Orthomyxoviridae Infections Pulmonary Alveoli Rodent Diseases Spleen Viral Load Abstract: To determine if fatal infections caused by different highly virulent influenza A viruses share the same ...
Analysis of benzophenone and 4-methylbenzophenone in breakfast cereals using ultrasonic extraction in combination with gas chromatography-tandem mass spectrometry (GC-MS(n)).
used to cure ink on carton boards. In this contribution, a fast and reliable method for the determination of BP and 4MBP in breakfast cereals is described. The sample was extracted ultrasonically using ...
Passive protection afforded by maternally-derived antibodies in chickens and the antibodies' interference with the protection elicited by avian influenza-inactivated vaccines in progeny.
two vaccinations are recommended for optimal protection. Also, it might be advisable to take into account day-old AI MDA titers when one is determining the optimal age of vaccination. Health Topics: ...
Rapid detection of Eurasian and American H7 subtype influenza A viruses using a single TaqManMGB real-time RT-PCR.
determined with the use of serial dilutions of Eurasian isolates A/Ck/ BE /06775/2003 and A/Ck/It/1067/v99 and North American isolates A/ CK / PA / 143586/2001 and A/Quail/ PA /20304/1998, to be 1 log10 higher ...
