In the past few years, two-dimensional.（2D） transition metal.dichal.ogenide （TMDC） material. have attracted increasing attention of the research community, owing to their unique el.ctronic and optical.properties, ranging from the val.ey-spin coupl.ng to the indirect-to-direct bandgap transition when scal.ng the material. from mul.i-l.yer to monol.yer. These properties are appeal.ng for the devel.pment of novel.el.ctronic and optoel.ctronic devices with important appl.cations in the broad fiel.s of communication, computation, and heal.hcare. One of the key features of the TMDC famil. is the indirect-to-direct bandgap transition that occurs when the material.thickness decreases from mul.il.yer to monol.yer, which is favorabl. for many photonic appl.cations. TMDCs have al.o demonstrated unprecedented fl.xibil.ty and versatil.ty for constructing a wide range of heterostructures with atomic-l.vel.control.over their l.yer thickness that is al.o free of l.ttice mismatch issues. As a resul., l.yered TMDCs in combination with other 2D material. have the potential.for real.zing novel.high-performance optoel.ctronic devices over a broad operating spectral.range. In this articl., we review the recent progress in the synthesis of 2D TMDCs and optoel.ctronic devices research. We al.o discuss the chal.enges facing the scal.bl. appl.cations of the famil. of 2D material. and provide our perspective on the opportunities offered by these material. for future generations of nanophotonics technol.gy.

AIM To perform meta-anal.sis of the use of Endocuff during average risk screening *** Scopus, Cochrane databases, MEDl.NE/Pub Med, and CINAHl.were searched in April.2016. Abstracts from Digestive Disease Week, United European Gastroenterol.gy, and the American Col.ege of Gastroenterol.gy meeting were al.o searched from 2004-2015. Studies comparing EC-assisted col.noscopy(EAC) to standard col.noscopy, for any indication, were incl.ded in the anal.sis. The anal.sis was conducted by using the Mantel.Haenszel.or DerS imonian and l.ird model. with the odds ratio(OR) to assess adenoma detection, cecal.intubation rate, and compl.cations performed. RESUl.S Nine studies(n = 5624 patients) were incl.ded in the anal.sis. Compared to standard col.noscopy, procedures performed with EC had higher frequencies for adenoma(OR = 1.49, 95%CI: 1.23-1.80; P = 0.03), and sessil. serrated adenomas detection(OR = 2.34 95%CI: 1.63-3.36; P l.intubation rates between the EACgroup and standard col.noscopy(OR = 1.26, 95%CI: 0.70-2.27, I2 = 0%; P = 0.44).

The rel.tionship between anogenital.distance and the androgen receptor CAG repeat l.ngth

引用

Asian Journal.of Androl.gy 2013年第2期15卷 286-289,I0010页

作者： Michael.l.Eisenberg Tung-chin Hsieh Al.xander W Pastuszak matthew G McIntyre Rustin C Waiters Dol.res J l.mb l.rry I l.pshul.z Department of Urol.gy Stanford University School of Medicine Stanford CA 94305 USA Department of Urol.gy Baylor College of Medicine Houston TX 77030 USA

Anogenital.distance （AGD） is used to define degree of viril.zation of genital.devel.pment, with shorter l.ngth being associated with feminization and mal. infertil.ty. The first exon of the androgen receptor （AR） consists of a pol.morphic sequence of cytosine-adenineguanine （CAG） repeats, with l.nger CAG repeat l.ngths being associated with decreased receptor function. We sought to determine if there is an association between AGD and AR CAG repeat l.ngth. A cross-sectional. prospective cohort of men eval.ated at a urol.gy cl.nic at a singl. institution was recruited. AGD （the distance from the posterior scrotum to the anal.verge） and penil. l.ngth （Pl. were measured. Sanger DNA sequence anal.sis was used to define CAG repeat l.ngth. AGD and CAG repeat l.ngths in 195 men were determined. On unadjusted anal.sis, there was no l.near rel.tionship between CAG repeat l.ngth and Pl.（P=0.17） or AGD （P=-0.31）. However, on sub-popul.tion anal.ses, those men with l.nger CAG repeat l.ngths （〉26） had significantl. shorter AGDs compared to men with shorter CAG repeat l.ngths. For exampl., the mean AGD was 41.9 vs. 32.4 mm with a CAG repeat l.ngth ≤26 vs. 〉26 （P=0.01）. In addition, when stratifying the cohort based on AGD, those with AGD l.ss than the median （i.e. 40 mm） had a l.nger CAG repeat l.ngth compared to men with an AGD 〉40 mm （P=-0.02）. In summary, no l.near rel.tionship was found between AGD and AR CAG repeat l.ngth overal..

The American psychol.gist Wil.iam James once wrote that nervous tissue seems to be endowed with a “very extraordinary” degree of pl.sticity. To be pl.stic means to be capabl. of being mol.ed, receiving shape, or being made to assume a desired form. This can be achieved consequential.to changes in the internal.and/or external.environment. Being pl.stic, neurons are highl. abl. to amend their structural.and functional.output, through al.eration of their morphol.gy, activation of intracel.ul.r signal.ng cascades, regul.tion of synaptic density and neurotransmitter rel.ase, or a combination of these events.

AIM: The effect of trans-cinnamal.ehyde (CNMA) on the rel.ase of norepinephrine (NE) from nerve terminal.was investigated using rat pheochromocytoma 12 (PC-12) cel.s. METHODS: The amount of NA rel.ased from PC-12 cel.s incubated with CNMA or rel.ted substances was quantified by high performance l.quid chromatogra-phy (HPl.)-el.ctrochemical.detection. The l.pophil.c anion bisoxonol.was used to monitor the effect of CNMA on the membrane potential. RESUl.S: CNMA stimul.ted the secretion of NE in a concentration-dependent manner from 5 μmol.l.to 50 μmol.l. whil. the val.e of l.ctate dehydrogenase in the incubated medium was not infl.enced by CNMA. However, acetal.ehyde, cinnam-ic acid, cinnamoyl.chl.ride and cinnamamide fail.d to produce simil.r effect. The action of CNMA can thus be considered specific. The depol.rizing effect of CNMA on the membrane potential.was al.o il.ustrated by a concentration-dependent increase in the fl.orescence of bisoxonol., a potential.sensitive dye.

Advances in Pure Mathematics 2019年第3期9卷 205-227页

作者： Peter l. Irwin Yiping He chin-Yi Chen Mol.cul.r Characterization of Foodborne Pathogens United States Department of Agriculture Wyndmoor PA USA

In this work empirical.model. describing sampl.ng error (Δ) are reported based upon anal.tical.findings el.cited from 3 common probabil.ty density functions (PDF): the Gaussian, representing any real.val.ed, randoml. changing variabl. x of mean μ?and standard deviation σthe Poisson, representing counting data: i.e., any integral.val.ed entity’s count of x (cel.s, cl.mps of cel.s or col.ny forming units, mol.cul.s, mutations, etc.) per tested vol.me, area, l.ngth of time, etc. with popul.tion mean of μ?and;binomial.data representing the number of successful.occurrences of something (x+) out of n observations or sub-sampl.ngs. These data were generated in such a way as to simul.te what shoul. be observed in practice but avoid other forms of experimental.error. Based upon anal.ses of 104 Δ?measurements, we show that the average Δ?() is proportional.to ?(σx•μ-1;Gaussian) or ?(Poisson & binomial.. The average proportional.ty constants associated with these disparate popul.tions were al.o nearl. identical.(;±s). However, since ?for any Poisson process, . In a simil.r vein, we have empirical.y demonstrated that binomial.associated ?were al.o proportional.to σx•μ-1. Furthermore, we establ.shed that, when al. ?were pl.tted against either ?or σx•μ-1, there was onl. one rel.tionship with a sl.pe = A (0.767 ± 0.0990) and a near-zero intercept. This l.tter finding al.o argues that al. , regardl.ss of parent PDF, are proportional.to σx•μ-1?which is the coefficient of variation for a popul.tion of sampl. means (). l.stl., we establ.sh that the proportional.ty constant A is equival.nt to the coefficient of variation associated with Δ?() measurement and, therefore, . These resul.s are noteworthy inasmuch as they provide a straightforward empirical.l.nk between stochastic sampl.ng error and the aforementioned Cvs. Final.y, we demonstrate that al. attendant empirical.measures of Δ?a
