The determination of contamination levels requires accredited laboratories, approved and certified procedures and methods, transparency and above all prompt results, as stakeholders in ...

We have developed the world's first optical spectroscopy-based system for bulk stable isotope analysis of 13C. The system is based on a novel universal interface, named LIAISON, capable of coupling to almost any CO2-generating sample preparation front-end ranging from an elemental analyzer to any dissolved carbon analysis module, which are of significant use in geochemical, ...

Many agencies recommend that health care workers wear N95 filtering facepiece respirators (N95-FFR) to minimize occupational exposure to bioaerosols, such as tuberculosis and pandemic influenza. Published standards outline procedures for the proper selection of an N95-FFR model, including user seal checks and respirator fit-testing. Some health officials have argued that the respirator fit-test ...

It has recently been proposed that plasma levels of 4?-hydroxycholesterol (4?HC) may be indicative of cytochrome P450 3A4 (P450 3A) activity and therefore could be used to probe for P450 3A-mediated drug-drug interactions. With this in mind, we describe a highly sensitive and precise liquid chromatography-electrospray ionization-tandem mass spectrometry method for the measurement of 4?HC in human ...

DNA fingerprinting allows the verification of conventional methods used to implement beef traceability. At any point along the supply chain, the identity of an animal or piece of meat can be checked by comparison of its DNA profile with an initial sample. Practical application of DNA fingerprinting to trace beef requires a choice of DNA markers as well as the optimization of ...

Solid-state NMR spectroscopy (SSNMR) is an extremely powerful technique for the analysis of pharmaceutical dosage forms. A major limitation of SSNMR is the number of samples that can be analyzed in a given period of time. A solid-state magic-angle spinning (MAS) probe that can simultaneously acquire up to seven SSNMR spectra is being developed to increase ...

The neutron-induced fission cross section of U-235 is not only one of the most-frequently used references but is also of direct importance in reactor applications. As a consequence, knowledge of this cross section is required with approx. 1% uncertainty as reflected in corresponding entries in request lists, which have persisted since the last 10 to 15 years. Measurements to that level of accuracy ...

PURPOSE: Adrenal venous sampling (AVS) is limited by technical failures that result from incorrect catheter placement or failure to catheterize the right adrenal vein. The existence of an inadequate sample may not be recognized at the time of the procedure, which can lead to nondiagnostic results. Rapid assay of serum cortisol levels allows for ...

This article presents for the first time the joint use of ionic liquid-based single drop microextraction (IL-SDME) and ion mobility spectrometry (IMS) for the determination of 2,4,6-trichloroanisol (2,4,6-TCA) in water and wine samples. An imidazolium-based IL was used as extractant taking into account both, its affinity for the analyte and its negligible response in the ...

The prognostic value of assessing minimal residual disease (MRD) in leukemia has been established with advancements in flow cytometry and PCR. Nonetheless, these techniques are limited by high equipment costs, complex, and costly cell processing and the need for highly trained personnel. Here, we demonstrate the potential of exploiting differences in the relative intensities of backscattered light ...

15N detection of mechanically aligned membrane proteins benefits from large sample volumes that compensate for the low sensitivity of the observe nuclei, dilute sample preparation, and for the poor filling factor arising from the presence of alignment plates. Use of larger multi-tuned solenoids, however, is limited by wavelength effects that lead to ...
