Irradiated recipient mice (7 5 Gy) were infused by BMC exposed to

Irradiated recipient mice (7.5 Gy) were infused by BMC exposed to 6 and 8 cGy. The counts of recipients’ peripheral blood cells (PBC) and bone marrow mononuclear cells (BMMNC) were monitored at the 5th, 10th, 15th, and 30th day

after BMC infusion. The colony-forming units in the recipient spleens (CFU-S) were calculated at the 10th day after infusion.

Results: Exposed to 6 and 8 cGy, BMC demonstrated significant selleck chemicals llc proliferative activities in vitro. When the recipient mice receiving BMC pre-exposed to low dose radiation (6 and 8 cGy), the counts of white blood cell (WBC), BMMNC and CFU-S were consistently higher than those in control.

Conclusions: BMC of donor irradiated by LDR in vitro may facilitate the hematopoietic reconstitution of the recipient

“A transport and gain model is developed for the recently realized ambipolar dual-wavelength terahertz quantum cascade laser. The model is based on the simplified density matrix formalism, describing the population and coherence terms of five relevant states per period, which includes the laser optical field and single-temperature thermal balance. Using the measured current densities under forward and reverse bias for calibration, a good theoretical/experimental agreement is found for the current-optical power characteristics and the laser dynamic range. This shows that the model is a reliable analyzer, if not yet a fully predictive tool, click here for quantum cascade laser simulation. (C)

“Poly(acrylic acid amidoxime) [P(AA-AO)] and poly(maleic acid amidoxime) [P(MA-AO)] resins were prepared by the gamma-radiation-induced copolymerization of acrylonitrile with acrylic acid and maleic acid, respectively. The obtained resins were amidoximated by reaction with hydroxylamine. The prepared resins were used for the removal of methyl violet (MV) dye from aqueous solutions. Batch adsorption studies were made by the measurement of the effects of pH, the amount of adsorbent, the contact time, and the adsorbate concentration. The adsorption isotherm of MV onto P(AA-AO) and P(MA-AO) was determined at 25 C with initial MV dye concentrations of 10-70 mg/L. The equilibrium data were analyzed with the Langmuir 4EGI-1 and Freundlich isotherm models. The equilibrium process was described well by the Langmuir isotherm model with maximum adsorption capacities of 398.4 and 396.8 mg/L for P(AA-AO) and P(MA-AO), respectively. The kinetics of adsorption of MV onto P(AA-AO) and P(MA-AO) are discussed. The pseudo-second-order kinetic model described the adsorption of MV onto P(AA-AO) and P(MA-AO) very well.
