Medical artificial intelligence (AI) promotes technological revolution and industrial transformation in the medical field, and the medical level of orbital disease will also be improved with the in-depth development of AI diagnosis and treatment. The problems should be solved in the orbital disease AI research at the initial stage include: the complex knowledge system of orbital disease requires cross-disciplinary knowledge to improve the level of diagnosis and treatment; the early diagnosis and treatment of orbital disease is absent, and effective technical methods are needed to crack the screening dilemma; the operation of the disease is difficult, and special mechanical devices are needed to break through the boundaries of surgical technique; the medical team of orbital disease is scarce, and it is necessary to share the medical resources effectively. In order to solve the problems mentioned above, the following research directions of orbital disease AI diagnosis and treatment should be included: the orbital disease AI diagnosis system, the orbital disease AI screening platform, the orbital surgery robot and the orbital disease telemedicine. Through the development of multidisciplinary diagnosis and treatment, the in-depth exploration of interdisciplinary basic research, the extensive implementation of clinical research, and the extensive integration of industry and academic communication, the AI diagnosis and treatment of orbital disease is approaching a new era.

To investigate the expression of OCT4 and its clinical significance in laryngeal squamous carcinoma tissues.Immunohistochemical staining was used to analyze the expression of OCT4 in 61 cases of laryngeal squamous carcinoma and 10 cases of the adjacent normal laryngeal tissues.The expression of OCT4 was not detected in normal laryngeal tissues, but could be detected in the nucleus of laryngeal carcinoma. The positive expression rates of OCT4 in well-moderately differentiated and poorly differentiated laryngeal squamous carcinoma tissues were 25.6% (11/43) and 66.7% (12/18) respectively, and there were significant differences (p0.01). The expression of the OCT4 protein was related to lymph node metastasis and TNM stage (p0.05), but not to gender, age and position of the tumor (p0.05).OCT4 is expressed in laryngeal squamous carcinoma tissues and is closely related to the cell differentiation of laryngeal carcinoma, lymph node metastasis and clinical stage.

Prostate cancer is a kind of malignancy with high occurrence in the male urogenital system. However, the mechanism of the occurrence, the progression, and the metastasis of prostate cancer are still unclear. Searching for the effective molecule target is of great significance to improve the curative effect on prostate cancer. Zinc finger E box binding protein-1 (ZEB1) protein is a member of the zinc finger transcription factor family that participates in the embryonic development and formation. ZEB1 was found to be involved in the occurrence and in the development of multiple cancers, while its role in prostate cancer still needs elucidation.Normal prostate cell line PC-3M and prostate cancer cell line DU145 were cultured in vitro and transfected by ZEB1 siRNA. ZEB1 mRNA and protein expressions were detected by real-time PCR and Western blot assay. Cell proliferation was determined by using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. Cell migration was evaluated by transwell assay. Cell apoptosis was evaluated by caspase-3 activity. The impact of ZEB1 on extracellular signal-regulated kinase 1 and 2 (ERK1/2) signaling pathway was assessed by Western blot assay.ZEB1 expression significantly increased in DU145 cells compared with PC-3M cells (p0.05). ZEB1 mRNA and protein obviously declined, cell proliferation inhibited, cell invasion suppressed, and Caspase-3 activity enhanced in DU145 cells after ZEB1 siRNA transfection (p0.05). ZEB1 siRNA markedly decreased ERK1/2 phosphorylation in DU145 cells compared with control (p0.05).Inhibition of ZEB1 promoted prostate cancer apoptosis, restrained proliferation, and suppressed invasion through down-regulating ERK1/2 signaling pathway.

Aloe vera has been widely investigated and used as folk medicine since ancient time. Biologically active substances in its gel include polysaccharides, glycoprotein, enzymes, anthraquinones or phenolic compounds, vitamins, minerals, and so on, which play important roles in anti-inflammatory response, antimicrobial, antiviral, antioxidant activity, immunoregulation effects, and especially in wound healing. In this paper, we review the advances in the mechanism and clinical application of Aloe vera and its extract on wound healing, so as to provide new ideas for the treatment of various kinds of wounds.

The thermostable β-glucosidase A (TmBglA) from Thermotoga maritima is a promising biocatalyst for production of isoflavone aglycones. Use of enzymes with high specificity for soy isoflavone conjugates is however essential for efficient hydrolysis. The effect of the amino acids located in the aglycone binding pocket with non-conserved residues between specificity groups in family 1 glycoside hydrolase (GH1) was studied using wild-type TmBglA and 3 exchange mutants (M1-TmBglA, M2-TmBglA, M1M2-TmBglA). Three mutants were expressed in Escherichia coli, purified and characterized. They had shifts in both optimum temperature and thermal stability, and their narrowing pH-activity curve caused by removing the ionized side chain in mutation. All mutants demonstrated the decreased catalytic efficiency more effectively revealed with natural glycoside, salicin, than with artificial substrate, p-nitrophenyl-β-D-glucopyranoside, suggesting that these amino acids are the key residues to determine aglycone specificity. A lower hydrolysis of genistin and daidzin for M2-TmBglA than M1-TmBglA indicated that L400, A407 and E408 being preferable to V170, A171, V173, G174 and H180 residues of Tm-BglA could be essential for soy isoflavone glycoside binding and catalysis.

A concrete surface was treated by in situ synthesised super-absorbent resin (SAR) of poly(acrylic acid-co-acrylamide). Experiments aimed at determining the resistance to carbonation and the chloride permeability of SAR-treated concrete compared with control concrete specimens were conducted. The corrosion risk and corrosion rate for the rebar embedded in SAR-treated and control concrete specimens at various periods of carbonation were evaluated through the accelerated corrosion test, wherein the rebar was subjected to 3·5% sodium chloride solution. The results show that the resistance to carbonation and chloride permeability of SAR-treated concrete is higher than that of control concrete, and that the corrosion risk and corrosion rate of steel embedded in SAR-treated concrete is smaller than that of steel in control concrete. Lighter carbonation can effectively decrease the chloride permeability of concrete, but serious carbonation is harmful to the long-term maintenance of the passive film of steel in concrete.

The DØ experiment enjoyed a very successful data-collection run at the Fermilab Tevatron collider between 1992 and 1996. Since then, the detector has been upgraded to take advantage of improvements to the Tevatron and to enhance its physics capabilities. We describe the new elements of the detector, including the silicon microstrip tracker, central fiber tracker, solenoidal magnet, preshower detectors, forward muon detector, and forward proton detector. The uranium/liquid-argon calorimeters and central muon detector, remaining from Run I, are discussed briefly. We also present the associated electronics, triggering, and data acquisition systems, along with the design and implementation of software specific to DØ. © 2006 Elsevier B.V. All rights reserved.

Made available in DSpace on 2022-04-28T20:06:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2005-10-07 We have performed a search for neutral Higgs bosons produced in association with bottom quarks in pp collisions, using 260pb-1 of data collected with the D0 detector in Run II of the Fermilab Tevatron Collider. The cross sections for these processes are enhanced in many extensions of the standard model (SM), such as in its minimal supersymmetric extension at large tanâ□¡Î. The results of our analysis agree with expectations from the SM, and we use our measurements to set upper limits on the production of neutral Higgs bosons in the mass range of 90 to 150 GeV. © 2005 The American Physical Society.

To test the effects of TNF-α inhibitor Etanercept on myocardial ischemia/reperfusion (MI/R) injury in posttraumatic mice, and explore related mechanisms.Traumatic mouse model was established with Noble-Collip drum. Five days after trauma, Notch1 was knocked down by intramyocardial injection of Notch1 small interfering RNAs (siRNA) or scrambled siRNA (20 μg). Seven days after trauma, mice were subjected to MI/R (30 minutes ischemia followed by reperfusion). Sham operation was similarly performed without coronary artery ligation. Ten minutes before reperfusion, mice received Etanercept (8 mg/kg, i. p.). ELISA was used to detect plasma levels of TNF-α and troponin I (cTnI) and myocardial nitrotyrosine content. Twenty-four hours after reperfusion, left ventricular ejection fraction (LVEF) was measured by echocardiography. Infarct size was determined by Evans blue/2, 3, 5-triphenyl tetrazolium chloride (TTC) double staining. Cardiac caspase-3 activity was detected using a caspase-3 kit. Myocardial TNF-α and Notch1 intracellular domains (Notch1 ICD) expressions were determined by Western blot. Chemiluminescence was used to assess myocardial superoxide anion content.(1) Compared to vehicle group, Etanercept treatment significantly reduced cTnI content, infarct size and caspase-3 activity (all P0.01), while obviously increased LVEF (P0.01). (2) Etanercept treatment also significantly reduced plasma and myocardial TNF-α contents (P0.01), whereas markedly increased myocardial Notch1 ICD content (P0.05). (3) Compared to scrambled siRNA group, Notch1 deficiency significantly increased cTnI content, infarct size and caspase-3 activity (P0.05), whereas obviously reduced LVEF (P0.05). (4) Etanercept significantly reduced myocardial superoxide anion and nitrotyrosine content (P0.01), which was reversed by downregulation of Notch1 (P0.05).TNF-α inhibitor Etanercept can alleviate MI/R injury after trauma by reducing myocardial oxidative/nitrative stress via activating Notch1 signaling pathway.

This article reports on the effects of dental adjustment parameters on stress and damage induced in a leucite-reinforced glass ceramic using a high-speed dental handpiece and coarse diamond burs. As one of machinable dental ceramics for prosthetic restorations, a leucite-reinforced glass ceramic has higher fracture toughness than feldspar porcelains. However, the extent of subsurface damage and stress induced in clinical dental adjustments is unknown. Tensile, shear, compressive and von Mises stresses at the bur-ceramic interface were investigated as functions of dental adjustment parameters using finite element analysis (FEA). The depths of subsurface damage were predicted using FEA according to the maximum principal stress criterion and experimentally measured using scanning electron microscopy (SEM). The resulting predicted subsurface damage depths agree well with the experimentally measured data. Both adjustment parameters, depth of cut and feed rate, were found to have significant influences on adjustment-induced stresses (P < 0.01) and subsurface damage (P < 0.01). It is also found that the predicted and measured subsurface damage depths increased linearly with the diamond grit depth of cut.

Sulfate attack is a key factor that results in the deterioration of concrete. In the current paper, a novel method to improve the sulfate resistance of concrete by surface treatment with super-absorbent resin (SAR) synthesised in situ is presented. The precursor solution of poly(acrylic acid-co-acrylamide) is soaked into the capillary pores of hardened concrete, initiated by infrared radiation and synthesised SAR, then the swollen SAR absorbs water and fills capillary pores to cut off the penetration pipes of external sulfates. The performances of SAR synthesised in situ were characterised by the swelling ratio for deionised water and 5% sodium sulfate solution. The osmosis of [Formula: see text] in cement mortar was compared before and after being treated by SAR. The sulfate corrosion characteristics of cement mortar were confirmed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The laboratory testing results indicate that the SAR has a high swelling ratio, and the swollen SAR, which adhered to the capillary pores of cement mortar, can evidently reduce the osmosis of [Formula: see text] in cement mortar. After being subjected to sodium sulfate attack, the cement mortar specimens treated by SAR were not severely deteriorated.

The objective of this investigation was to map QTL controlling oil, protein, and starch concentrations in maize grain and to evaluate their genetic effects. The mapping population included 298 F2:3 family lines containing Beijing high-oil (BHO) maize germplasm. F2 individuals were genotyped with 183 SSR markers to construct a genetic linkage map, which spanned 1,605.7 cM, with an average interval of 8.77 cM. Oil, protein, and starch concentrations in grain among F2:3 families were measured by near-infrared (NIR) analyzer. Using QTL Cartographer, we mapped six QTL associated with oil in grain, six associated with protein, and five associated with starch concentrations. The proportion of phenotypic variation explained by single QTL ranged from 4.34 to 13.13% for oil, from 5.19 to 6.66% for protein, and from 4.14 to 7.85% for starch concentrations. QTL for oil, protein, or starch concentrations were often detected in identical intervals and the direction of their effects were consistent with the sign of their phenotypic correlation. They were considered as common QTL for chemical compositions in maize grain. In this study, we identified three QTL for oil in grain, two QTL for protein, and three QTL for starch concentrations, which were on identical or similar chromosomal locations to those previously mapped with Illinois high-oil (IHO) maize germplasm. These suggests that more diverse germplasm should be necessary to detect additional QTL and to discover more favorable alleles for chemical composition of maize grain.

We present the measurement of R = B(t -> Wb)/B(t -> Wq) in pp collisions at root s = 1.96 TeV, using 230 pb(-1) of data collected by the DO experiment at the Fermilab Tevatron Collider. We fit simultaneously R and the number (N-tt) of selected top quark pairs (tt), to the number of identified b-quark jets in events with one electron or one muon, three or more jets, and high transverse energy imbalance. To improve sensitivity, kinematical properties of events with no identified b-quark jets are included in the fit. We measure R = 1.03(-0.17)(0.19) (stat + syst), in good agreement with the standard model. We set lower limits of R > 0.61 and vertical bar V-tb vertical bar > 0.78 at 95% confidence level.

The results of a search for squarks and gluinos using data from p p ¯ collisions recorded at a center-of-mass energy of 1.96 TeV by the DO detector at the Fermilab Tevatron Collider are reported. The topologies analyzed consist of acoplanar-jet and multijet events with large missing transverse energy. No evidence for the production of squarks or gluinos was found in a data sample of 310 pb−1. Lower limits of 325 and 241 GeV were derived at the 95% C.L. on the squark and gluino masses, respectively, within the framework of minimal supergravity with tan β = 3 , A 0 = 0 , and μ 0 .

We report on a search for the pair production of second generation scalar leptoquarks (LQ_2) in ppbar collisions at the center-of-mass energy sqrt(s) = 1.96 TeV, using data corresponding to an integrated luminosity of 294 +- 19 pb^-1 recorded with the D0 detector. No evidence for a leptoquark signal in the LQ_2 LQ_2 -> muq muq channel has been observed, and upper bounds on the product of cross section times branching fraction were set. This yields lower mass limits of m(LQ_2) > 247 GeV for beta = Br(LQ_2->muq) = 1 and m(LQ_2) > 182 GeV for beta = 1/2. Combining these limits with previous D0 results, the lower limits on the mass of a second generation scalar leptoquark are m(LQ_2) > 251 GeV and m(LQ_2) > 204 GeV for beta = 1 and beta = 1/2, respectively.

We present a measurement of the top quark pair ($t\bar{t}$) production cross section ($\sigma_{t\bar{t}}$) in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV using 230 pb$^{-1}$ of data collected by the D0 experiment at the Fermilab Tevatron Collider. We select events with one charged lepton (electron or muon), missing transverse energy, and jets in the final state. We employ lifetime-based b-jet identification techniques to further enhance the $t\bar{t}$ purity of the selected sample. For a top quark mass of 175 GeV, we measure $\sigma_{t\bar{t}}=8.6^{+1.6}_{-1.5}(stat.+syst.)\pm 0.6(lumi.)$ pb, in agreement with the standard model expectation

We present a search for electroweak production of single top quarks in the s-channel and t-channel using neural networks for signal-background separation. We have analyzed 230 pb(-1) of data collected with the DO detector at the Fermilab Tevatron Collider at a center-of-mass energy of 1.96 TeV and find no evidence for a single top quark signal. The resulting 95% confidence level upper limits on the single top quark production cross sections are 6.4 pb in the s-channel and 5.0 ph in the t-channel. (c) 2005 Elsevier B.V. All rights reserved.

The D0 collaboration has performed a study of spin correlation in tt-bar production for the process tt-bar to bb-bar W^+W^-, where the W bosons decay to e-nu or mu-nu. A sample of six events was collected during an exposure of the D0 detector to an integrated luminosity of approximately 125 pb^-1 of sqrt{s}=1.8 TeV pp-bar collisions. The standard model (SM) predicts that the short lifetime of the top quark ensures the transmission of any spin information at production to the tt-bar decay products. The degree of spin correlation is characterized by a correlation coefficient k. We find that k>-0.25 at the 68% confidence level, in agreement with the SM prediction of k=0.88.

of data collected with the DO detector during 1993-1995. We find that a(p (p) over bar --> W + X)B(W --> tau nu) = 2.22 +/- 0.09 (stat) +/- 0.10 (syst) +/- 0.10 (lum) nb. Lepton universality predicts that the ratio of the tau and electron electroweak charged current couplings to the W boson, g(T)(W)/g(e)(W), be unity. We find g(T)(W)/g(e)(W) = 0.980 +/- 0.031, in agreement with lepton universality.

Inclusive dijet production at large pseudorapidity intervals (Delta eta) between the two jets has been suggested as a regime for observing Balitsky-Fadin-Kuraev-Lipatov (BFKL) dynamics. We have measured the dijet cross section for large Delta eta in p (p) over bar collisions at root s = 1800 and 630 GeV using the D0 detector. The partonic cross section increases strongly with the size of Delta eta; The observed growth is even stronger than expected on the basis of BFKL resummation in the leading logarithmic approximation. The growth of the partonic cross section can be accommodated with an effective BFKL intercept of alpha(BFKL)(20 GeV) = 1.65 +/- 0.07.

This Letter describes a measurement of the muon cross section originating from b quark decay in the forward rapidity range 2.4 < y(mu) < 3.2 in pbarp collisions at sqrt(s) = 1.8 TeV. The data used in this analysis were collected by the D0 experiment at the Fermilab Tevatron. We find that NLO QCD calculations underestimate b quark production by a factor of four in the forward rapidity region. A cross section measurement using muon+jet data has been included in this version of the paper.

We present a measurement of the transverse momentum distribution of Z bosons produced in ppbar collisions at sqrt{s}=1.8 TeV using data collected by the D0 experiment at the Fermilab Tevatron Collider during 1994--1996. We find good agreement between our data and a current resummation calculation. We also use our data to extract values of the non-perturbative parameters for a particular version of the resummation formalism, obtaining significantly more precise values than previous determinations.

A sample of 3.79 million psi(2S) decays observed in the BES detector is used to study the decays of charmonium to axialvector plus pseudoscalar mesons. The branching fraction for psi(2S) to b1pi agrees with expectations. A contrasting behavior between the psi(2S) and the J/psi decays to K1K cannot be accommodated by an adjustment of the singlet-triplet axialvector mixing angle., 7 pages, 3 figures.

A partial wave analysis of BES J / ψ → γ ( ηπ + π − ) data has been performed in the mass region 1.1 to 2.0 GeV. A peak is observed due to η (1440) in the ηπ + π − invariant mass distribution; J P =0 − is preferred over 1 + . Its mass is M =1385±7 MeV and it decays into both ησ and a 0 (980) π , with BR[ a 0 (980) π , a 0 → ηπ / ησ ]=0.70±0.12( stat )±0.20( syst ). Destructive interference between the two decay modes is observed. In addition, in the higher ηπ + π − mass region, there is a definite 2 −+ signal, with M =1840±15 MeV and Γ =170±40 MeV and an additional 0 −+ signal at 1760±35 MeV. We also find a possible contribution from a 1 ++ signal decaying dominantly through a 0 (980) π ; its mass and width are fitted to be M =1505±20 MeV and Γ =130 −20 +50 MeV.

We determine upper limits on branching fractions for ψ(2S) decays into ωf2, ρa2, K*0K*02 + c.c., and φf'2(1525) that are, in each case, significantly smaller than the corresponding branching fractions for the J/ψ meson, scaled according to the expectations of perturbative QCD. © 1998 The American Physical Society.

Purely leptonic decays of the charged D meson have been studied using the reaction e + e − →D ∗+ D − at a center of mass energy of 4.03 GeV. A search was performed for D→μνμ recoiling against a D0 or D+ which had been reconstructed from its hadronic decay products. A single event candidate was found in the reaction e + e − →D ∗+ D − , where D ∗+ →π + D 0 with the D0→K−π+, and the recoiling D− decaying via D − →μ − ν μ . This yields a branching fraction value B(D→μνμ)=0.08−0.05−0.02+0.16+0.05%, and a corresponding value of the pseudoscalar decay constant fD=300−150−40+180+80 MeV.

With 7.8 million produced J / ψ events collected by the BES detector at the BEPC, decays J/ψ→Λ Λ ,Λ Λ γ and Λ Λ π 0 are analysed. The branching ratios are measured to be Br (J/ψ→Λ Λ )=(1.08±0.06±0.24)×10 −3 , Br (J/ψ→Λ Λ γ) −4 (90% C.L. ) , Br (J/ψ→Λ Λ π 0 )=(2.3±0.7±0.8)×10 −4 , respectively. The angular distribution for J/ψ→Λ Λ is of the form d N d cos θ =N 0 (1+α cos 2 θ) , from which we determine α =0.52±0.33±0.13.

A search is performed for the production of the ψ(2S) in e^+e^- annihilation at a center-of-mass energy of 4.03 GeV using the BES detector operated at the Beijing Electron Positron Collider (BEPC). The kinematic features of the reconstructed ψ(2S) signal are consistent with its being produced only in association with an energetic photon resulting from initial state radiation (ISR). Limits are placed on ψ(2S) production from the decay of unknown charmonia or metastable hybrids that might be produced in e^+e^- annihilations at 4.03 GeV. Under the assumption that the observed cross section for ψ(2S) production is due entirely to ISR, the partial width Γ_(ee) of the ψ(2S) is measured to be 2.07±0.32keV.

The absolute inclusive branching fraction of D_s^+→φX^+ has been measured from data collected by the BES detector at a center-of-mass energy of 4.03 GeV, corresponding to an integrated luminosity of 22.3 pb^(-1). At this energy, direct pair production e^+e^-→D_s^+D_s^- has been observed. We have selected D_s candidate events by reconstructing five hadronic decay modes D_s^+→φπ^+, K^(0*)K^+, K^0K^+, f0^(π+) and K^0K^-π^+π^+ and have searched for inclusive φ’s in the recoiling D_s^-. We observed three recoiling φ’s in the 166.4 ± 31.8 D_s candidate events, which leads to the absolute branching fraction B(D_s^+→φX^+)=(17.8(-7.2 -6.3)^(+15.1+0.6)) % and B(D_s-6.3+→φπ-6.3+)=(3.6_(-1.6 -1.3)(^_3.1+0.4) %.
