In this paper, a new conception of linguistic q-rung orthopair fuzzy number (Lq-ROFN) is proposed where the membership and nonmembership numbers ( q-ROFNs) are represented as variables. Compared with intuitionistic Pythagorean numbers, Lq-ROFNs can more fully describe assessment information by considering parameter q to adjust range information. To deal multiple-attribute group decision-making (MAGDM) problems Lq-ROFNs, we score accuracy functions Lq-ROFNs. Further, introduce prove...

Linguistic q-rung orthopair fuzzy numbers (Lq-ROFNs) are a qualitative form of (q-ROFNs) where the membership and nonmembership degrees represented by linguistic variables. The Lq-ROFNs can describe broader range assessment information flexibly adjusting parameter q based on different situations, so they more superior to intuitionistic Pythagorean in real application. Based Lq-ROFNs, we introduce entropy measure which be used determine indefiniteness information. Then, measure, further...

Materials and methods: We studied biomarkers intestinal permeability 126 people with MS (57 relapsing-remitting (RRMS) 69 progressive MS) group healthy controls comparison. Serum/plasma concentrations zonulin (a regulator enterocyte tight junctions), junction proteins (ZO-1 occludin), fatty acid binding protein (IFABP)/ileal bile (IBABP), D-lactate, lipopolysaccharide (LPS) were...

Regeneration of peripheral nerves involves complex and intimate interactions between axons Schwann cells. Here, we show that local axon synthesis action the neuropeptide calcitonin gene-related peptide (CGRP) is critical for this collaboration. After sural sensory injury in rats, observed an unexpectedly large proportion newly expressed CGRP during regeneration. Intense expression accompanied rises αCGRP mRNA nerve trunk, there was evidence transport into regenerating axons, indicating...

Background Although over 1400 Salmonella serovars cause usually self-limited gastroenteritis in humans, a few, e.g., typhi and S. paratyphi C, typhoid, potentially fatal systemic infection. It is not known whether the typhoid agents have evolved from common ancestor (by divergent processes) or acquired similar pathogenic traits independently convergent processes). Comparison of different with non-typhoidal lineages will provide excellent models for studies on how pathogens might evolved....

Abstract Background Because human diets are composed of a wide variety nutrients that may work synergistically to prevent or promote disease, assessing dietary nutrient intake status be informative. The purpose this study was assess the Chinese adults with metabolic syndrome (MetS) and evaluate its possible role in MetS. Methods This case–control conducted from March 2010 January 2011. A total 123 patients MetS 135 controls participated at Health Examination Center Heping District Tianjin,...

Visceral fat area (VFA), a novel sex-specific index for visceral obesity (VFO) might play major role in the development of vitamin D deficiency. However, association between VFA and insufficiency deficiency Chinese population is less clear. The aim this study was to explore population-level among men women. This cross-sectional involved 1105 adults aged 20–70 years living Tianjin who were randomly selected medically examined. All subjects underwent bioelectrical impedance analysis (BIA)...

Biorenewable lignin has been used as a precursor to produce varieties of carbon materials. However, up now, it not easy obtain graphitic carbon-encapsulated metal materials without high-temperature process. Here, we demonstrate an antiprogrammed temperature pyrolysis route for the fabrication iron encapsulated in thin-walled layers with low temperature. The industrially available was biorenewable source, and ferric nitrates were sources. We found that process during carbonization is critical...

Salmonella enterica serovar Pullorum is a fowl-adapted bacterial pathogen that causes dysentery (pullorum disease). Host adaptation and special pathogenesis make S. an exceptionally good system for studies of evolution speciation, especially regarding pathogen-host interactions the acquisition pathogenicity. We constructed genome map RKS5078, using I-CeuI, XbaI, AvrII, SpeI Tn10 insertions. Pulsed-field gel electrophoresis was employed to separate large DNA fragments generated by...

GAP-43 is a neuronal calmodulin-binding phosphoprotein that concentrated in growth cones and presynaptic terminals. By sequencing tryptic endoproteinase Asp-N phosphopeptides directly determining the release of radioactive phosphate, we have identified three sites (serines 41 96 threonine 172) are phosphorylated, both cultured neurons neonatal rat brain. These account for most 32PO4 was incorporated into neurons; 8-15% each site occupied with phosphate isolated from Phosphorylation serine...

Bio-renewable lignin has been used as a carbon source for the preparation of porous materials. Nevertheless, up to now, there are few studies about influence molecular weight on structure and morphology ordered mesoporous carbon. Here, we synthesized derived from different weights Pluronic F127. Fortunately, found that is an important factor obtaining highly channels, high specific surface area, More importantly, narrow well-defined channel could exert spatial restriction effect some extent,...

Genome plasticity resulting from frequent rearrangement of the bacterial genome is a fascinating but poorly understood phenomenon. First reported in Salmonella typhi, it has been observed only small number serovars, although over 2,500 known serovars are all very closely related. To gain insights into this phenomenon and elucidate its roles evolution, especially those involved formation particular pathogens, we systematically analyzed genomes 127 wild-type S. typhi strains isolated many...

Failure of axons to regenerate following acute or chronic neuronal injury is attributed both the inhibitory glial environment and deficient intrinsic ability re-grow. However, underlying mechanisms latter remain unclear. In this study, we have investigated role mammalian homologue aspergillus nidulans NudE, Ndel1, emergently viewed as an integrator cytoskeleton, in axon regeneration. Ndel1 was synthesized de novo upregulated crushed transected sciatic nerve axons, and, upon injury, strongly...
