OBJECTIVES HIV-positive people have increased risk of infection-related malignancies (IRMs) and infection-unrelated malignancies (IURMs). The aim of the study was to determine the impact of aging on future IRM and IURM incidence. METHODS People enrolled in EuroSIDA and followed from the latest of the first visit or 1 January 2001 until the last visit or death were included in the study. Poiss...

We pilot tested a novel human factors-informed concept to identify infectious risk moments (IRMs) that occur with high frequency during routine intensive care. Following 30 observation-hours, 28 potential IRMs related to hand hygiene, gloves, and objects were expert rated. A comprehensive IRM inventory may provide valuable taxonomy for research, training, and intervention.

Pollen grains from grasses using the C3 and C4 photosynthetic pathways have distinct ranges of d C values that may be used to estimate their relative abundance in paleorecords. We evaluated a spooling-wire microcombustion device interfaced with an isotope-ratio mass spectrometer (SWiM-IRMS) for dC analysis of individual grass-pollen grains. Pollen from four C3 and four C4 grass species was isol...

The article draws our attention to studying the phenomenon of Russian Music Society (RMS) in Far-Eastern Republic (FER), one regions Russia history which is inscribed space musical culture. Exceeding boundaries Far Eastern regional studies, authors accentuate their on line succession allows them speak about as successor Imperial (IRMS) during period political modernization country provided tran...

The essential oils of wintergreen and birch are composed primarily methyl salicylate. Because this compound can easily be synthesized, frequently adulterated. By using Gas chromatography-combustion/pyrolysis-isotope ratio mass spectrometry (GC-C/P-IRMS) in conjunction with TC/EA-IRMS, GC-FID, GC-MS, 14C radiocarbon dating, criteria will established that used to distinguish authentic natural fro...

Gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) is increasingly applied to food and metabolic studies for stable isotope analysis (δ(13) C), with the quantification of analyte concentration often obtained via a second alternative method. We describe a rapid direct transesterification of triacylglycerides (TAGs) for fatty acid methyl ester (FAME) analysis by GC-C-IRMS d...

Nonliving antiviral vaccines traditionally target proteins expressed at the surface of the virion with the hope of inducing neutralizing antibodies. Orthopoxviruses (OPVs), such as the human smallpox virus and the mouse-equivalent ectromelia virus (ECTV; an agent of mousepox), encode immune response modifiers (IRMs) that can increase virulence by decreasing the host immune response. We show tha...

The administration of synthetic steroid copies is one of the most important issues facing sports. Doping control laboratories accredited by the World Anti-Doping Agency (WADA) require methods of analysis that allow endogenous steroids to be distinguished from their synthetic analogs in urine. The ability to measure isotope distribution at natural abundance with high accuracy and precision has i...

The innate immune system critically shapes diabetogenic adaptive immunity during type 1 diabetes (T1D) pathogenesis. While the role of tissue-infiltrating monocyte-derived macrophages in T1D is well established, the role of their tissue-resident counterparts remains undefined. We now demonstrate that islet resident macrophages (IRMs) from non-autoimmune mice have an immunoregulatory phenotype a...

In this study, dC values of six cocaine samples were identified and classified using a single quadrupole mass spectrometer and an isotope ratio mass spectrometry (IRMS) as simultaneous gas chromatography detectors. Our instrument modification is simple to use and is useful (i) when the sample is of limited size or can only be injected once, (ii) to help identify peaks in a complicated IRMS chro...
