Dear Editor,Of all human tumors,pheochromocytomas and paragangliomas(ppGLs)have the highest heritability *** 15%of ppGLs harbor mutations in genes encoding tricarboxylic acid(TCA)cycle-related enzymes that cause oncometabolite accumulation and drive tumorigenesis via metabolic adaptation to hypoxia and global hypermethylation[1].The dihydrolipoamide S-succinyltransferase(DLST)gene was recently described as a new ppGL susceptibility gene[2].

An Evolutionary Approach to the Delineation of Functional Areas Based on Travel-to-work Flows

引用

International Journal of Automation and computing 2008年第1期5卷 10-21页

作者： Francisco Flórez-Revuelta Josémanuel Casado-Díaz Lucas martínez-Bernabeu Department of Computing Technology University of AlicanteP.O.Box 99E-03080AlicanteSpain Institute of International Economics University of AlicanteP.O.Box 99F-03080AlicanteSpain

This paper presents a new approach to the delineation of local labor markets based on evolutionary computation. The aim of the exercise is the division of a given territory into functional regions based on travel-to-work flows. Such regions are defined so that a high degree of inter-regional separation and of intra-regional integration in both cases in terms of commuting flows is guaranteed. Additional requirements include the absence of overlap between delineated regions and the exhaustive coverage of the whole territory. The procedure is based on the maximization of a fitness function that measures aggregate intra-region interaction under constraints of inter-region separation and minimum size. In the experimentation stage, two variations of the fitness function are used, and the process is also applied as a final stage for the optimization of the results from one of the most successful existing methods, which are used by the British authorities for the delineation of travel-to-work areas （TTWAs）. The empirical exercise is conducted using real data for a sufficiently large territory that is considered to be representative given the density and variety of travel-to-work patterns that it embraces. The paper includes the quantitative comparison with alternative traditional methods, the assessment of the performance of the set of operators which has been specifically designed to handle the regionalization problem and the evaluation of the convergence process. The robustness of the solutions, something crucial in a research and policy-making context, is also discussed in the paper.

Anchor Root Development: A World within Worlds

引用

Molecular plant 2020年第8期13卷 1105-1107页

作者： Josémanuel pérez-pérez Instituto de Bioingeniería Universidad Miguel Hernández03202 ElcheSpain

Many plant species develop shoot-borne adventitious roots(ARs)with specialized functions that contribute to plant adaptability by enhancing resource capture and stress *** Arabidopsis,as in many dicots,the postembryonic root system is primarily composed of lateral roots(LRs),which originate from the xylem pole pericycle cells through a process that involves periodic oscillation in gene expression mediated by a β-carotenoidderived signal(Dickinson et al.,2019).Our understanding of the key molecular and signaling events regulating AR initiation has recently been obtained from studies in Arabidopsis,where ARs are formed on etiolated hypocotyls upon transfer to light(Lakehal et al.,2019)or from excised leaf explants(Zhang et al.,2019).Anchor roots(ANRs)are a type of AR that originate immediately below the root-hypocotyl junction in an auxindependent manner and that require a diapocarotenoid-derived signal(anchorene)to emerge(Jia et al.,2019).ANR primordia activation may represent a generic mechanism to compensate for the loss of the growth potential of the primary root(pR),as it is enhanced by mutations affecting pR growth,by whole-root excision or by nitrogen deficiency(Jia et al.,2019).A recent paper by Bai et al.(2020)provides direct evidence that a regulatory module involving the Ap2/ERF transcription factor ABSCISIC ACID INSENSITIVE 4(ABI4),the mitogen-activated protein kinases(MApKs)MpK3 and MpK6,and the phosphatase pp2C12 controls ANR emergence in Arabidopsis.

Influence of steel jacket thickness on the RC bridges' seismic vulnerability

引用

Journal of Traffic and Transportation Engineering(English Edition) 2019年第1期6卷 15-34页

作者： Bertha Olmos José manuel Jara Gerardo Gómez Guillermo martínez Department of Civil Engineering Universidad Michoacana de San Nicolas de Hidalgo

The seismic demands of bridges subjected to strong earthquakes are mostly concentrated on piers. The main objective of this study is to assess the seismic vulnerability of retrofitted bridges with steel jackets. It analyzes the influence of the steel jacket thickness on the seismic capacity and demand of bridges. The bridges in study have two simple supported spans with superstructure composed by AASHTO type girders and a substructure formed with one circular pier over a stiff foundation. They are located on the pacific coast of Mexico that is a zone of high seismicity. The bridges seismic capacity are evaluated through nonlinear static analyses and the shear force and displacement demands were determined using capacity spectra with a group of 10 real accelerograms from a subduction source. The response spectra were scaled to several peak ground accelerations(pGA) with the aim to estimate four damage scenarios linked each one to a probability of exceedance in a specific period, for return periods in the range of 72-3500 years that represent service level and maximum considered earthquake. Results show that the confining effect provided by the steel jackets substantially improves the seismic performance of the bridges piers. The increase of jacket thickness guides to important increments on columns base shear capacity, and the influence of the steel jacket thickness depends on the limit state and bridge slenderness ratio.

Clinical significance of"anti-HBc alone"in human immunodeficiency virus-positive patients

AIM： TO determine the prevalence and clinical relevance of isolated antibodies to hepatitis B core antigen as the only marker of infection （“anti-HBc alone”） among human immunodeficiency virus （HIV） type-1 infected patients. Occult hepatitis B infection frequency was also evaluated. METHODS： Three hundred and forty eight histories from 2388 HIV-positive patients were randomly reviewed. patients with serological markers of hepatitis B virus （HBV） infection were classified into three groups： past hepatitis, ＂anti-HBc alone＂ and chronic hepatitis. Determination of DNA from HBV, and RNA and genotype from hepatitis C virus （HCV） were performed on ＂anti-HBc alone＂ patients. RESULTS： One hundred and eighty seven （53.7%） HIV-positive patients had markers of HBV infection： 118 past infection （63.1%）, 14 chronic hepatitis （7.5%） and 55 ＂anti-HBc alone＂（29.4%）. Younger age [2.3-fold higher per every 10 years younger; 95% confidence intervals （Cl） 1.33-4.00] and antibodies to HCV infection [odds ratio （OR） 2.87; 95% CI 1.10-7.48] were factors independently associated with the ＂anti-HBc alone＂ pattern. No differences in liver disease frequency were detected between both groups. Serum levels of anti-HBs were not associated with HCV infection （nor viral replication or HCV genotype）, or with HIV replication or CD4 level. No ＂anti-HBc alone＂ patient tested positive for HBV DNA. CONCLUSION：＂Anti-HBc alone＂ prevalence in HIM- positive patients was similar to previously reported data and was associated with a younger age and with antibodies to HCV infection. In clinical practice, HBV DNA determination should be performed only in those patients with clinical or analytical signs of liver injury,
