Development of a Carbon Mesh Supported Thin Film Microextraction Membrane As a Means to Lower the Detection Limits of Benchtop and Portable GC/MS Instrumentation.
Waterloo, Canada. In Anal Chem, Feb 2016
With the use of hand-portable GC-TMS instrumentation, membranes cut with dimensions 40 mm long by 4.85 mm wide and 40 ± 5 μm thick (per side) were shown to extract 21.2, 19.8, 18.5, 18,4, 26.8, and 23.7 times the amount of 2,4 dichlorophenol, 2,4,6 trichlorophenol, phorate D10, fonofos, chloropyrifos, and parathion, respectively, within 15 min from a 10 ppb aqueous solution as compared to a 65 μm DVB/PDMS solid phase microextraction (SPME) fiber.
Genetic variations in CHRNA7 or CHRFAM7 and susceptibility to dementia.
Roma, Italy. In Curr Drug Targets, 2012
evidence on the association between variations in CHRNA7 or CHRFAM7A and the risk of dementia is still sparse and inconclusive. Further studies are needed to establish whether some polymorphisms may affect the probability of developing dementia [review]
