Rabbit anti-Human HLX1 polyclonal antibody

Hydrogen production by the sulfur-iodine (SI) process, with an electrodialysis (ED) stack embedded in the HI decomposition section (SEC3) to concentrate HI in the HIx solution and overcome the pseudo-azeotrope, was conducted under pressurized conditions. The HIx solution of H2O/HI = 5.63-6.13 and I-2/HI = 0.57-1.97 was supplied to the SEC3. HI gas was concentrated in a packed distillation column and decomposed over Pt/Al2O3. The experimental results of distillation column operation under different feed rates and HIx compositions are reported. The raffinate from the column showed a pseudo-azeotropic Hlx mixture, as predicted in previous research. The dynamic responses of the ED stack were examined during the start-up period according to the HIx feed composition at the anode inlet. The ED voltage changed with the I-2 concentration in the inlet flow. The proton transport number (t(+)) and electro-osmosis coefficient (beta) were estimated for the ED stack during the operations. Hydrogen production ranged from 18.3 to 50 L/h, depending on the operating conditions and HIx feed composition. Copyright (c) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.

Type 1 helper T (T(H)1) cells are essential for cellular immunity, but their ontogeny, maturation and durability remain poorly understood. By constructing a dominant-negative form of T-bet, we were able to determine the role played by this lineage-inducing trans-activator in the establishment and maintenance of heritable T(H)1 gene expression. Optimal induction of interferon-gamma (IFN-gamma) expression required genetic interaction between T-bet and its target, the homeoprotein Hlx. In fully mature T(H)1 cells, reiteration of IFN-gamma expression and stable chromatin remodeling became relatively independent of T-bet activity and coincided with demethylation of DNA. In contrast, some lineage attributes, such as expression of IL-12Rbeta2 (interleukin 12 receptor beta2), required ongoing T-bet activity in mature THI cells and their progeny. These findings suggest that heritable states of gene expression might be maintained by continued expression of the inducing factor or by a mechanism that confers a stable imprint of the induced state.
