Abstract:

Abstract Background: Prognostication in MF has historically been based on age, symptoms and hematologic features at presentation. Newer models include cytogenetic and genomic data given their independent prognostic value. In 2014, two prognostic models incorporating gene mutation data were proposed: a "mutation enhanced" IPSS (MIPSS) and a genetics-based prognostic scoring system (GPSS) model; the former using mutation data to enrich standard prognostic inputs, while the latter eschewed classic prognostic inputs for a score comprised solely of cytogenetics, mutation data, and age (Vannucchi, B

Abstract:

Growth of the axial and appendicular skeleton depends on endochondral ossification, which is controlled by tightly regulated cell–cell interactions in the developing growth plates. Previous studies have uncovered an important role of a disintegrin and metalloprotease 17 (ADAM17) in the normal development of the mineralized zone of hypertrophic chondrocytes during endochondral ossification. ADAM17 regulates EGF-receptor signaling by cleaving EGFR-ligands such as TGFα from their membrane-anchored precursor. The activity of ADAM17 is controlled by two regulatory binding partners, the inactive Rho

The activation process is the final stage in the manufacturing of activated carbon that can be carried out physically or chemically. This paper focuses on characterizing the surface properties of activated carbons from Gigantochloa verticillata bamboo that are chemically activated at 750°C under different impregnation ratios (IRs) of 1:1, 2:1, and 3:1. The activated carbons produced were denoted as IR1-AC, IR2-AC, and IR3-AC for impregnation ratios of 1:1, 2:1, and 3:1, respectively.

Abstract:

AbstractThe indide YIrIn was synthesized from the elements in a sealed tantalum ampoule in a high-frequency furnace. YIrIn adopts the ZrNiAl type. The crystal structure was refined from single-crystal X-ray diffractometer data: P6–2m, a = 750.63(6), c = 392.04(3) pm, wR = 0.0346, 308 F2 values and 16 variables. Refinement of the occupancy parameters revealed a small degree of Ir/In mixing (0.912(9) Ir2/0.088(9) In1) on the 2d site. The YIrIn structure contains two crystallographically independent iridium sites, both with tri-capped trigonal prismatic coordination: Ir1@In6Y3 and Ir2@In3Y6.

ABSTRACT The BvgAS signal transduction system of Bordetella controls an entire spectrum of gene expression states in response to differences in environmental conditions. In particular, the Bordetella Bvg-intermediate-phase gene bipA displays a complex regulatory pattern in response to various concentrations of modulators. Expression of bipA is low in the absence of modulating signals, maximal at intermediate concentrations of modulators, and near background levels at high concentrations of modulators. bipA is regulated at the transcriptional level, and the bipA promoter contains multiple BvgA

Abstract:

Trade-in strategy is a common mode of promotion for firms taking part in the circular economy because it encourages consumers to buy remanufactured products, via a “trade-old-for-remanufactured” framework. This paper studies trade-in strategy by developing game models for a closed-loop supply chain with one manufacturer and two independent remanufacturers. The former is responsible for producing and selling new products and the latter two compete with each other for the collection of used products and the sales of remanufactured products.

Abstract:

Background: Changes of direction (COD) repeated sprints (RSs) might have greater relevance to football than linear RSs. We aimed to compare the effects of linear and COD RSs on intermittent high intensity running (HIR) over an entire season. Methods: In total, 19 high-level male football players (16–19 years) randomly performed linear RSs or COD RSs twice a week during their competitive season over 22 weeks. Yo-Yo intermittent recovery test level 2 (Yo-Yo IR2), and 10- and 20-m sprint was assessed pre-, mid- (11 weeks), and post-intervention (22 weeks). Maximal oxygen uptake (VO2max) was asses

Abstract:

As an important part of fusion materials research, evaluation of radiation damage in fusion materials has been emphasized more than a half century. In order to improve our understanding of radiation damage in fusion materials, an upgrade has been performed of the materials irradiation facility IR2, which is located at the NCSR “Demokritos” 5.5 MV TANDEM accelerator. The upgraded facility allows irradiation at higher ion beam currents while ensuring that the target temperature remains below 10 K. It provides in-situ electrical resistivity measurements on several samples for real-time monitoring

AbstractPutative iron-reductase (IR) genes from Serpula lacrymans with similarity to the conserved iron-binding domains of cellobiose dehydrogenase (CDH) enzymes have been identified. These genes were cloned and expressed to functionally characterize their activity and role in the decomposition of lignocellulose. The results show that IR1 and IR2 recombinant enzymes have the ability to depolymerize both lignin and cellulose, are capable of the reduction of ferric iron to the ferrous form, and are capable of the degradation of nitrated lignin.

Abstract:

ABSTRACT The mitotic stability of the linear plasmid-prophage N15 of Escherichia coli depends on a partition system closely related to that of the F plasmid SopABC. The two Sop systems are distinguished mainly by the arrangement of their centromeric SopB-binding sites, clustered in F (sopC) and dispersed in N15 (IR1 to IR4). Because two of the N15 inverted repeat (IR) sites are located close to elements presumed (by analogy with phage λ) to regulate late gene expression during the lytic growth of N15, we asked whether Sop partition functions play a role in this process. In N15, a putative Q an

Six synthetic peptides (C1 to C6), which reproduced the six IR sequences were used as peptide-based, enzyme-linked immunosorbent assay (ELISA) antigens. Two IRs, IR2 and IR6, were found to be immunodominant. Studies with serially collected serum samples from experimentally infected dogs revealed that the antibody response to IR6 appears earlier a
