Hemoglobin-based oxygen carriers have long been pursued to meet clinical needs by using native hemoglobin (Hb) from human or animal blood, recombinantly produced Hb, but the development has impeded safety and toxicity issues. Herewith we report successful production of fetal (HbF) in Nicotiana benthamiana through Agrobacterium tumefaciens-mediated transient expression. HbF is a heterotetrameric...

To devise an activation technique for characterizing mixed radiation fields, secondary particles from a copper target irradiated by 24 GeV/c protons were measured at the CERN High-energy AcceleRator Mixed field facility (CHARM). Activation detector sets consisting of aluminum, niobium, indium, and bismuth, placed 30 cm angles 15° to 160° with respect beam axis. The nuclides generated in these d...

a simple, selective and efficient solid phase extraction method based on the use of  γ-alumina nanoparticles coated with sodium dodecyl sulfate (sds) and modified with 2-​(5-​bromo-​2-​pyridylazo)​-​5-​(diethylamino) ​phenol (5-br-padap) as a new adsorbent was developed for the separation and preconcentration of trace amounts of manganese (ii) prior to determination by flame atomic absorption s...

Hydrodistilled essential oil of the aerial parts of Laggera crispata (Vahl) Hepper & Wood, collected from the Kumaon region of the western Himalayas was analysed by gas chromatography and gas chromatography–mass spectrometry. Eighty constituents, accounting for 83.9 % of the total oil composition, were identified. The oil was mainly dominated by sesquiterpenoids (45.3 %) and benzenoid compounds...

The activity per unit mass of an iodine-131 solution was absolutely standardized by both the 4πβ-γ coincidence method and the 4πγ counting technique. The calibrated solution was used to prepare point sources after a preliminary deposit of AgNO3 to prevent the loss of volatile iodine. Relative and absolute photon emission intensities of 15 sgamma-rays and those of the two K X-rays of xenon were ...

Mass spectrometry-based in vitro kinase screens play an essential role in the discovery of kinase substrates, however, many suffer from biological and technical noise or necessitate genetically-altered enzyme-cofactor systems. We describe a method that combines stable γ-[(18)O2]-ATP with classical in vitro kinase assays within a contemporary quantitative proteomic workflow. Our approach improve...

The oxidation of neopentane was studied in jet-stirred reactors at atmospheric pressure over a temperature range 500–850 K and ϕ = 0.5. products were analyzed with chromatographic, mass spectrometric, photoelectron spectroscopic setups complemented theoretical calculations. This combination provides comparison photo-ionization spectrometry gas chromatography for the quantification mole fraction...

• Neutron/γ–ray discrimination via optical light filtration instead of PSD methods. Study the CVL in CLYC: an ultra-fast mechanism emitting deep-near UV. Correlation between time and wavelength domain scintillation light. RL spectra with TCSPC technique a fast PMT results. LET dependence quenching effect on emission CLYC. 7 Li enriched Cs 2 LiYCl 6 :Ce 3+ (CLYC) is promising inorganic scintilla...

Concern has been expressed following the adoption of average β and γ energies taken from TAGS (total absorption gamma-ray spectrometry) for decay-heat calculations (Yoshida et al., 2004). As a consequence of these difficulties, experimental efforts are being made to resolve the current uncertainties in the β-strength distributions of some of the most relevant decayheat radionuclides and to addr...
