We investigated the association of HLA class II alleles and haplotypes with sickle cell anemia vaso-occlusive crisis (VOC). DRB1*100101 was positively associated, while DRB1*140101, DRB1*150101, and DQB1*060101 were negatively associated, with VOC. Both susceptible (DRB1*100101-DQB1*050101) and protective (DRB1*110101-DQB1*030101 and DRB1*150101-DQB1*060101) haplotypes were identified, indicati...

Selected Volatile Organic Compounds (VOC) emitted from various anthropogenic sources including industries and motor vehicles act as primary precursors of ozone, while some VOC are classified as air toxic compounds. Significantly large VOC emission sources impact the air quality in Corpus Christi, Texas. This urban area is located in a semi-arid region of South Texas and is home to several large...

Volatile organic compound (VOC) profiles are potentially an underutilized class of threat agent signatures that may be exploited in the identification of threat agents. In the present study we first focused on determining if VOC profiles collected from liquid culture headspace could be utilized to differentiate between bacterium of different genus, in this case Bacillus and Yersinia. The second...

A ‘virtual’ disjunct eddy covariance (vDEC) device was tested with field measurements of biogenic VOC fluxes at a subalpine forest site in the Rocky Mountains of the USA. A PTR-MS instrument was used as the VOC sensor. Daily peak emission fluxes of 2-methyl-3-buten-2-ol (MBO), methanol, acetone and acetaldehyde were around 1.5, 1, 0.8 and 0.4 mg m−2 h−1, respectively. High pass filtering due to...

Regenerative Thermal Oxidizer (RTO) is one of the best solutions for removal of Volatile Organic Compounds (VOC) from industrial processes. In the RTO, VOC in a raw gas are usually decomposed at 950-1300 K and the combustion heat of VOC is recovered by regenerative heat exchangers charged with ceramic honeycombs. The optimization of the treatment of VOC leads to the reduction of fuel addition t...

102 ambient VOC species were measured online by a gas chromatography-mass spectrometry/flame ionization detector (GC/MS-FID) at an urban site in Beijing during a heavy pollution episode in December 2014. VOC sources were identified by correlation analysis of particular species pairs. The interspecies correlations of benzene-acetylene, toluene-acetylene, isobutane-propane and ethane-propane were...

Hemolytic transfusion reactions (HTRs) can produce serious and potentially life-threatening complications in sickle cell disease (SCD) patients; however, the mechanisms underlying these complications remain undetermined. We established a model of alloimmune, IgG-mediated HTRs in a well-characterized humanized murine model of SCD. HTRs induced acute vaso-occlusive crisis (VOC), resulting in shor...

Thanks to the use of a sustainable FeIII-based deep eutectic solvent (DES) as promoter/reaction medium, alkynes were hydrated under bench-type reaction conditions (45 °C, air, absence co-catalysts or co-solvents). This Fe-DES could be recycled for up eight consecutives runs in any VOC (E factor = 10). Furthermore, is able promote efficient formal oxidation internal into 1,2-diketones, with syst...
