Long noncoding RNA (lncRNA) is emerging as a vital regulator in various tumors. However, the biological function of ZFPM2-antisense RNA 1 (ZFPM2-AS1) in hepatocellular carcinoma (HCC) remains unclear. The present study aims to explore the function and mechanism of ZFPM2-AS1 in hepatocellular carcinoma progression.The ZFPM2-AS1 expression in HCC cells and tissues was measured by quantitative real-time polymerase chain reaction (qRT-PCR). Effects of ZFPM2-AS1 on tumor cell proliferation and invasion were detected by CCK8 assay or EdU assay or matrigel migration assay and Western blot. The Luciferase reporter assay, RNA pulldown assay, qRT-PCR, and Western blot were performed to explore and confirm the interaction between ZFPM2-AS1 and miR-1226-3p and integrin β1 (ITGB1).ZFPM2-AS1 was overexpressed in HCC tissues and cell lines. High levels of ZFPM2-AS1 were correlated with advanced TNM stage, distant metastasis and a poorer overall survival rate. ZFPM2-AS1 knockdown inhibited cell proliferation and invasion. ZFPM2-AS1 could directly bind to and negatively regulate miR-1226-3p expression. Moreover, ITGB1 was identified as a target gene of miR-1226-3p. ITGB1 was found to be directly negatively regulated by miR-1226-3p and indirectly upregulated by ZFPM2-AS1. Rescue assays demonstrated that ZFPM2-AS1 promotes HCC cell proliferation and invasion through modulating miR-1226/ITGB1 axis.ZFPM2-AS1 promotes cell proliferation and migration by regulating miR-1226-3p/ITGB1 axis in HCC.

The relationship between adiponectin (APN) pathway and Wnt pathway was explored through BMSCs, and the effect of low-level laser irradiation (LLLI) on bone marrow stromal cells (BMSCs) and its mechanism were further studied.3-week-old Sprague-Dawley (SD) rats were selected, and mesenchymal stem cells were separately cultured and purified. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to analyze cell proliferation. After osteogenic and adipogenic induction, cultures were conducted, respectively, cells were stained with alizarin red and oil red O. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expressions of osteogenesis-related genes, runt-related transcription factor 2 (RUNX2), and osteocalcin (OC) and those of adipogenesis-related genes, peroxisome proliferator-activated receptor-gamma (PPARγ) and CCAAT/enhancer-binding protein alpha (c/EBPα). Western blotting was used to detect the expressions of β-catenin in the cytoplasm and nucleus. The lentiviral expression vector of adiponectin receptors (APN-R) was constructed, and the expression of APN receptor genes was silenced. The expressions of β-catenin in APN receptors and the nucleus within cells were detected.LLLI promoted the bone formation by inducing the differentiation direction of mesenchymal stem cells, increasing the number of osteoblasts in the bone marrow and inhibiting the reduction of the number of adipocytes. LLLI regulates the Wnt pathway, promotes the entry of β-catenin into the nucleus, activates the osteogenic effect of the Wnt pathway so as to promote the bone formation of osteoblasts and inhibit bone resorption of osteoclasts. LLLI promotes the entry of β-catenin into the nucleus and the osteogenic differentiation of BMSCs through the APN pathway.In summary, LLLI can promote osteogenesis and inhibit adipocytes formation, thus attenuating bone resorption of osteoclasts. The mechanism of LLLI is that it promotes the entry of β-catenin into the nucleus and regulates the Wnt pathway and the differentiation direction of mesenchymal stem cells through the APN signal pathway, thus promoting bone formation.

Drought impacts severely crop photosynthesis and productivity. Development of transgenic rice overexpressing maize phosphoenolpyruvate carboxylase (PEPC) is a promising strategy for improving crop production under drought stress. However, the molecular mechanisms of protection from PEPC are not yet clear. The objective of this study was: first, to characterize the response of individual photosynthetic components to drought stress; second, to study the physiological and molecular mechanisms underlying the drought tolerance of transgenic rice (cv. Kitaake) over-expressing maize PEPC. Our results showed that PEPC overexpressing improved the ability of transgenic rice to conserve water and pigments during drying as compared to wild type. Despite the fact that drought induced reactive oxygen species and damaged photosystems (especially, PSI) in both lines, higher intercellular CO2 concentration protected the photosynthetic complexes, peptides, and also ultrastructure of thylakoid membranes against the oxidative damage in transgenic rice. In conclusion, although photosynthetic apparatus suffered an inevitable and asymmetric impairment during drought conditions, PEPC effectively alleviated the oxidative damage on photosystems and enhanced the drought tolerance by increasing intercellular CO2 concentration. Our investigation provided critical clues for exploring the feasibility of using C4 photosynthesis to increase the yield of rice under the aggravated global warming.

The S matrix ansatz is a rigorously model independent approach to describe the cross-sections and asymmetries in e+e- annihilation. Using the cross-sections and asymmetries measured with the L3 detector during the 1990 and 1991 running period, we determine the mass and the width of the Z boson, the contributions of the Z exchange and of the yZ interference. Including the polarization of the t lepton in the analysis, the leptonic helicity amplitudes of the scattering process are determined assuming lepton universality. The results are compared with other model independent ansatzes as realized in ZFITTER. A systematic bias of the Z mass due to the yZ interference term is detected, which leads to an underestimation of the error on mz for model independent determinations., Facultad de Ciencias Exactas

Breast cancer is one of the most aggressive and pervasive cancers identified in females. Dexmedetomidine (Dex) is an efficient anesthetic used in surgery. Our study aimed to explore the role of Dex in the malignancy of breast cancer cells in vitro and in vivo. Further, we investigate the molecular mechanism involved in the function of Dex on breast cancer cells.The methyl thiazolyl tetrazolium (MTT) assay was applied to detect cell proliferation. The migration and invasion capacity of MDA-MB-231 cells was tested by wound healing assay and transwell assay. Western blot analysis was performed to quantify the protein expression levels of α2-adrenoceptor and ERK.The proliferation, migration and invasion ability of MDA-MB-231 cells was gradually increased after treatment of Dex in a dose-dependent manner in vitro. In addition, Dex could significantly elevate the volume and weight of xenotransplant tumor in vivo. Furthermore, Dex up-regulated the protein level of a2-adrenoceptor and consistently enhanced the phosphorylation of ERK without changing the total level of it. Similarity, over-expression of a2-adrenoceptor via its agonist Clonidine could mimic the function of Dex on breast cancer.These data suggest that Dex could promote the proliferation, migration and invasion of breast cancer cells through the activation of α2B-adrenoceptor /ERK signaling.

A search for rare charmless decays of B0d and B0s mesons has been performed in the exclusive channels B0d(s) →ηη0, B0d(s) →ηπ0 and B0d(s) →π0π0. The data sample consisted of three million hadronic Z decays collected by the L3 experiment at LEP from 1991 through 1994. No candidate event has been observed and the following upper limits at 90% confidence level on the branching ratios have been set: Br(B0d→ηη) −4, Br(B0s →ηη) < 1.5 x 10−3, Br(B0d→ηπ0) < 2.5 x 10−4, Br(B0s→ηπ0) < 1.0 x 10−3, Br(B0d→π0π0) < 6.0 x 10−5, Br(B0s→π0π0) < 2.1 x 10−4.

Tramadol is used mainly for the treatment of moderate to severe chronic cancer pain. However, the effect of tramadol on lung cancer remains unclear. Therefore, it is important to explore the mechanism accounting for the function of tramadol on lung cancer.We investigated the effects of tramadol on the proliferation, migration and invasion in human lung adenocarcinoma cells in vitro by CCK-8 assay, wound healing assay and Transwell assay, respectively. We also explored the potential mechanism of tramadol on lung cancer cells by Western blotting.A549 and PC-9 cells were incubated with 2 µM tramadol for different time (0, 7, 14 and 28 d). The in vitro experiments showed that tramadol treatment significantly inhibited cell proliferation, migration and invasion in a time-dependent manner. Moreover, administration of tramadol suppressed tumor growth in vivo. The data also revealed that tramadol could up-regulate the protein expression level of PTEN and consistently inhibit the phosphorylation level of PI3K and Akt, whereas the total level of PI3K and Akt remain unchanged.These findings indicated that tramadol inhibited proliferation, migration and invasion of human lung adenocarcinoma cells through elevation of PTEN and inactivation of PI3K/Akt signaling.

The aim of this study was to examine the function of tramadol on cell proliferation, migration and invasion in breast cancer cells in vitro, and to evaluate the effect of tramadol in vivo. Further, we explore the mechanism accounting for the role of tramadol on breast cancer cells.Cell proliferation was detected by the methyl thiazolyl tetrazolium (MTT) assay. Wound healing assay and transwell assay was applied to quantify the migration and invasion ability of MDA-MB-231 cells. The expression of endogenous α2-adrenoceptor and ERK was measured by Western blotting.Tramadol at a clinical dose of up to 2 μM significantly inhibited the proliferation, migration and invasion in a time-dependent manner from day 0 to 28 in vitro. Moreover, tramadol suppressed the growth of xenotransplant tumor in vivo markedly. Furthermore, the protein levels of α2-adrenoceptor and phosphorylated ERK were decreased by tramadol, whereas the expression of total ERK remained unchanged. In addition, downregulation of α2-adrenoceptor by yohimbine could mimic the effect of tramadol treatment.Collectively, we demonstrated that tramadol could inhibit proliferation, migration and invasion of breast cancers via inactivating α2-adrenoceptor signaling pathway. Our data provide the experimental fundamental for further investigation of the anti-cancer effect of tramadol in breast cancer cells.

Lung cancer, including non-small cell lung cancer (NSCLC), is the leading cause of cancer-related mortality worldwide. Despite recent advances in clinical and experimental oncology, the prognosis of patients with NSCLC still remains poor and the average survival time of patients suffer from lung cancer is low. Therefore, the potential mechanism accounting for the tumorigenesis of NSCLC is still needed to be explored.A lentiviral vector over-expressing miR-26b in A549 lung cancer cells was constructed. Cell proliferation, migration and invasion analysis were measured by cell counting kit (MTT), would healing assay and Transwell assay. Direct target of miR-26b in A549 cells was examined using bioinformatics and Luciferase assay.Herein, we found that over-expression of miR-26b significantly inhibited the proliferation, migration and invasion of A549 lung cancer cell in vitro and suppressed the growth of established tumors in vivo. By using bioinformatics, we found that COX-2 (Cyclooxygenase-2) is one of the potential targets of miR-26b. Moreover, miR-26b was found to negatively regulate COX-2 protein level by directly targeting its 3'UTR. In addition, depletion of endogenous COX-2 by the specific siRNA could mimic the function of miR-26b overexpression.Taken together, our results demonstrate that miR-26b could suppress lung cancer cells proliferation, migration and invasion by directly negative regulation of COX-2. MiR-26b could serve as a novel potential marker for NSCLC therapy.

In the present study, we consider the bonding process of a pair of wafers with rough surfaces via an energy-rate concept in which "rate" refers to "area rate". A finite element numerical simulation for a rough surface with periodical distributed asperities bonded onto a rigid half-space is carried out for demonstrating the energy-rate concept. The simulation reveals various phenomena in the wafer bonding, such as self-activated bonding, asperity shape effect and plastic deformation effect in the bonding process.

Background: Local anesthetic containing epinephrine is commonly used in many operations for the main purpose of hemostasis. A randomized, controlled, prospective clinical trial was designed to find out hemodynamic changes after local infiltration of different concentrations and/or different dosages of epinephrine during functional endoscopic sinus surgery (FESS) under general anesthesia. Methods: One hundred and eight adult patients undergoing elective FESS under general anesthesia were randomly allocated into four groups. Group I received 2% lidocaine 2 ml with epinephrine (5 µg/ml); group II received 1% lidocaine 4 ml with epinephrine (2.5 µg/ml); group III received 1% lidocaine 4 ml with epinephrine (5 µg/ml); and group IV received 1% lidocaine 4 ml for local infiltration. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) were monitored continuously in the radial artery and recorded in 6 min: before infiltration (baseline), 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, and 6 min after local infiltration. The lowest blood pressure (BP) in this period was also recorded. Results: Significant hemodynamic changes, particularly a decrease in BP (P 0.05). Conclusion: Local infiltration of low-dose epinephrine causes temporary significant hemodynamic changes particularly a marked decrease in BP during FESS under general anesthesia.

We studied the effect of hydroxyethyl starch (HES) on intestinal production of cytokines and activation of transcription factors in sepsis. Septic rats, induced by intraperitoneal lipopolysaccharide (LPS) (5 mg/kg), were treated with intravenous HES (16 ml/kg) or saline (64 ml/kg). Rat ileal tissues were collected at 2 h, 3 h or 6 h after LPS challenge. Levels of tumour necrosis factor alpha (TNF-alpha), interleukin (IL) 1beta, IL-6, IL-8 and IL-10, cytokine mRNAs, activities of nuclear factor kappa-B (NF-KB) and activator protein-1 (AP-1), and the number of ileal myeloperoxidase (MPO)-positive cells were determined for each group. HES significantly reduced the LPS-induced increase in intestinal levels of TNF-alpha, IL-1beta, IL-6, IL-8 and their corresponding mRNAs. HES also decreased the number of MPO-positive cells induced by LPS and inhibited activation of NF-kappaB and AP-1. The results suggest that in sepsis, HES may down-regulate intestinal pro-inflammatory cytokine production via suppression of NF-kappaB and AP-1 activation.

In the present paper, micro-scale contact induced by liquid bridging is studied numerically via FEM with consideration of coupling effect between the liquid bridging and the elastic deformation of the half space. The variations of the liquid-bridging force and contact area as functions of a dimensionless parameter χ (measurement of relative stiffness of the contact bodies) and the filling angle ψ (measurement of liquid volume) are obtained and discussed. The FEM numerical solution is compared with two approximate analytical solutions based on Hertzian contact mechanics. It is found that the dimensionless liquid bridging force and contact area obtained via the approximate solutions are much smaller than the values obtained via FEM under certain conditions. The error inhabited in the approximate solution is due to the coupling effect between the liquid-bridging force and the elastic deformation of the half space.

BACKGROUND Ketamine has been advocated for anesthesia in endotoxemic and other severely ill patients because it is a cardiovascular stimulant. However, ketamine also suppresses serum levels of endotoxin-induced tumor necrosis factor-alpha, and reduces mortality in mice in endotoxin shock. Our study was designed to investigate the protective effect of ketamine on the endotoxin-induced proinflammatory cytokines and nuclear factor kappa B (NF-kappaB) activation in vivo. METHODS Adult male Wistar rats were randomly divided into six groups: saline controls; rats challenged with endotoxin (5 mg kg(-1)) and treated with saline; challenged with endotoxin (5 mg kg(-1)) and treated with ketamine (0.5 mg kg(-1)); challenged with endotoxin (5 mg kg(-1)) and treated with ketamine (5 mg kg(-1)); challenged with endotoxin (5 mg kg(-1)) and treated with ketamine (50 mg kg(-1)); and saline injected and treated with ketamine (50 mg kg(-1)). TNF-alpha, IL-6 and NF-kappaB were investigated in the tissues of the intestine (jejunum) after 1, 4 and 6 h. RESULTS Endotoxin caused transient production of TNF-alpha and IL-6 and activation of NF-kappaB in the intestine at peak times of 1, 4 and 1 h, respectively. Ketamine 0.5 mg kg(-1) suppressed endotoxin-induced TNF-alpha elevation and inhibited NF-kappaB activation in the intestine; a dose of 5 mg kg(-1) was required to inhibit IL-6. CONCLUSION Ketamine suppresses the production of proinflammatory cytokines such as TNF-alpha and IL-6 in the intestine, possibly via inhibition of NF-kappaB.

The effective electroweak mixing angle sin2θw is measured from the production and decay of the Z boson in e+e- interactions. The data sample corresponds to an integrated luminosity of 18 pb-l with about 420 000 hadronic and 40 000 leptonic Z decays. The mixing angle sin 22θw is determined from several independent measurements: the leptonic and hadronic cross sections, the forward-backward asymmetries of charged leptons and b-quarks, and the z-polarization. The results are found to be in good agreement with each other. The value of sin 22θw from a fit to the asymmetries in a model independent method is 0.2321-4-0.0021 and from a global fit to the data in the Standard Model framework is 0.2328±0.0013., Facultad de Ciencias Exactas

We report on a study of single W boson production in a data sample collected by the L3 detector at centre-of-mass energies from 130 to 183 GeV. The signal consists of large missing energy final states with a single energetic lepton or two hadronic jets. The measured cross sections at five different centre-of-mass energies are consistent with the Standard Model expectations. The following limits on the anomalous WW γ gauge couplings are derived at 95% CL: −0.46 Δκ γ λ γ

Time-dependent \({{\rm B^{0}}\mbox{-}\bar{{\rm B}}^{0}}\) mixing is studied using about two million hadronic Z decays registered by L3 in 1994 and 1995. For this study three techniques are used. Tagging of the b-quark charge at decay time is performed by identifying leptons from semileptonic B decays. The flavour of the b quark at production time is determined from the charge of the lepton in the opposite hemisphere or by using a jet-charge technique. The proper time of the B-particle decay is obtained by reconstructing the production and decay vertices or by a measurement of the lepton impact parameter. The combined result for the frequency of \({{\rm B_d^0}}\) meson oscillations is \(\)

An upper limit on the lifetime difference of short- and long-lived $\rm B^0_s$ mesons has been obtained using an inclusive bottom hadron sample from 2 million hadronic Z decays collected by the L3 experiment at LEP. A lifetime fit has been performed on data samples separately enriched in neutral and charged b hadrons. An experimental upper limit on the decay rate difference of short- and long-lived $\rm B^0_s$ mesons of \begin{displaymath} ~~~~ {\rm (|\Delta\Gamma|/\Gamma)_{B^0_s}} < 0.67 ~~~~~~~\mathrm{(95\% \; C.L.)} \end{displaymath} has been determined. In addition, the lifetimes of $\rm B^+$ and $\rm B^0_d$ mesons have been measured to be $\tau(\rm B^+) = 1.66 \pm 0.06 \, \pm 0.03 \; \mathrm{ps}$ and $\tau(\rm B^0_d) = 1.52 \pm 0.06 \, \pm 0.04 \; \mathrm{ps}$, where the first errors are statistical and the second are systematic.

Quantifying the biodegradation rate of organic contaminants is important in designing and evaluating bioremediation treatments and facilities. To study the effects of temperature and forced aeration on the biodegradation rate, a soil collected from a pipeline break site and contaminated with crude oil was bioremediated in a field-operated bioreactor near Nevis, AB, Canada under four treatments: a control with ambient temperature (averaging 20°C) and no forced aeration; heating alone (averaging 35°C); forced aeration alone (air flux was 0.41 min -1 m -2 ); and both heating and forced aeration. The soil was aggregated, amended with N and P fertilizers and packed 15-cm deep to a bulk density of 0.65 Mg m -3 in the bioreactor. The effect of temperature on the biodegradation rate of hydrocarbons was also studied under laboratory conditions for temperatures ranging from 5 to 50°C. Both heating and forced aeration significantly affected the biodegradation of hydrocarbons, but the effect of the former was greater. Under laboratory conditions, the biodegradation rate of hydrocarbons increased with temperatures, peaking between 30 and 40°C. The half-lives of the hydrocarbons remaining in soil in the field-operated bioreactor were 105 d for both the heating alone and the heating and forced aeration treatments, 182 d for the forced aeration treatment and 248 d for the control.

We have studied the process $e^+e^-{\rightarrow}\rm n {\gamma}$ $(\rm n{\ge}2)$ at centre-of-mass energies of 161.3 GeV and 172.1 GeV. The analysis is based on a sample of events collected by the L3 detector in 1996 corresponding to total integrated luminosities of 10.7 ${\rm pb^{-1}}$ and 10.1 ${\rm pb^{-1}}$ respectively. The observed rates of events with two and more photons and the characteristic distributions are in good agreement with the Standard Model expectations. This is used to set lower limits on contact interaction energy scale parameters, on the QED cut-off parameters and on the mass of excited electrons.

A search for unstable neutral and charged heavy leptons as well as for stable charged heavy leptons has been made at center-of-mass energies s = 161 GeV and s 172 GeV with the L3 detector at LEP. No evidence for their existence was found. We exclude unstable neutral leptons of Dirac (Majorana) type for masses below 78.0 (66.7), 78.0 (66.7) and 72.2 (58.2) GeV, if the heavy neutrino couples to the electron, muon or tau family, respectively. We exclude unstable charged heavy leptons for masses below 81.0 GeV for a wide mass range of the associated neutral heavy lepton. The production of stable charged heavy leptons with a mass less than 84.2 GeV is also excluded. If the unstable charged heavy lepton decays via mixing into a massless neutrino, we exclude masses below 78.7 GeV.

We report on measurements of $\mathrm{e^+e^-}$ annihilation into hadrons and lepton pairs. The data have been taken with the L3 detector at LEP at centre--of--mass energies between 161~$\mathrm{Ge\kern -0.12em V}$ and 172~$\mathrm{Ge\kern -0.12em V}$. In a data sample corresponding to 21.2~pb$^{-1}$ of integrated luminosity 2728 hadronic and 868 lepton--pair events are selected. The measured cross sections and leptonic forward--backward asymmetries agree well with the Standard Model predictions. \end{abstract}

Nitrogen dynamics and cycling are important in plant-soil ecosystems, and they may differ between hydrocarbon-contaminated and uncontaminated soils. The objective of this experiment was to study the effects of petroleum hydrocarbons and remediation methods on nitrogen dynamics and cycling in plant-soil ecosystems. The experiment involved two plant species (barley and field pea) grown in soils at four different hydrocarbon levels (0, 5, 25 and 55 g kg−1). Hydrocarbon contamination significantly reduced N uptake by plants, but increased N accumulation in soil microbial biomass. It widened the C:N ratio in soil and led to more available N being immobilized by soil microorganisms, which reduced available N for plantuptake. Urease activity increased with hydrocarbon content in soil due to the increase of microbial biomass and activity. Key words: Nitrogen dynamics, hydrocarbon contamination, microbial activity, remediation, Black Chernozem

Using a data sample of 1 475 000 Z → qq(γ) events collected during 1994 with the L3 detector at LEP, we have studied the purely leptonic decays of heavy flavour mesons, D s − → τ − ν τ and B − → τ − ν τ . A signal is observed in the invariant mass distribution M(γD s − ) corresponding to the decay sequence D ∗− → γD s − , D s − → τ − ν τ , τ − → l − ν l ν τ . The branching fraction for D s − → τ − ν τ decays is measured to be β (D s − → τ − ν τ ) = 0.074 ± 0.028(stat) ± 0.016(syst) ± 0.018(norm) . No signal of B − → τ − ν τ decays is observed in the data, corresponding to an upper limit on the branching franction β( B − → τ − ν τ ) −4 at 90% CL.

We have searched for evidence of Upsilon production in 3.5 million hadronic Z decays collected by the L3 detector at LEP in 1991-1995. No signals are observed for the decay chain Z -> Upsilon X; Upsilon -> l+l- (l= e, mu), therefore upper limits at the 95% confidence level are set on the following Z branching fractions: BR (Z -> Upsilon(1S) X) < 5.5 x 10**-5; BR (Z -> Upsilon(2S) X) < 13.9 x 10**-5; BR (Z -> Upsilon(3S) X) < 9.4 x 10**-5.

We study the quasi-bound state and the transport properties in the T-shaped graphene nanoribbon consisting of a metallic armchair-edge ribbon connecting to a zigzag-edge sidearm. We systematically study the condition under which there are quasi-bound states in the system for a wide range of the system size. It is found that when the width of the sidearm is about half of the width of the armchair leads, there is a quasi-bound state trapped at the intersection of the T-shape structure. The quasi-bound states are truly localized in the sidearm but have small continuum components in the armchair leads. The quasi-bound states have strong effect on the transport between the armchair leads through the Fano effect, but do not affect the transport between the armchair lead and the sidearm., 5 pages, 4 figures

Background: Although aortic pulse wave velocity (PWV) has been accepted as gold standard of arterial stiffness, characteristics of PWVs in other arteries have never been reported. Methods: We measured carotid-femoral, carotid-pedis, carotid-radial, and femoral-pedis PWVs by a validated tonometry PulsePen, and assessed body fat percentage by bioelectrical impedance analyzer, carotid intima-media thickness (IMT) by ultrasonograph, and other cardiovascular risk factors, in 198 patients from our ambulatory cardiovascular department. Results: Carotid-femoral and carotid-pedis PWVs increased significantly and progressively with age in both men and women (P ≤ 0.03), whereas only in men, a slight increase and decrease in carotid-radial and femoral-pedis PWVs, respectively, were detected with aging (P ≤ 0.006). Carotid-femoral and carotid-pedis PWVs, but not carotid-radial and femoral-pedis PWVs, were significantly associated with age, body height and body fat percentage, brachial mean blood pressure (MBP), and pulse pressure (PP), carotid PP, PP amplification, carotid IMT, plasma glucose and taking antihypertensive agent (P ≤ 0.047). In full adjustment models, carotid-femoral PWV increased by 0.89 ± 0.21, 0.38 ± 0.13, 0.74 ± 0.26, 0.40 ± 0.16, 0.51 ± 0.23 m/s, with an increase of 10 years in age, of 1 mmol/l in plasma glucose, of 10 mmHg in brachial PP, of 100 μm in IMT, and of 10 mmHg in brachial MBP, respectively, whereas carotid-pedis PWV increased by 0.31 ± 0.11 and 0.33 ± 0.12 m/s with an increase of 10 years in age and of 10 mmHg in brachial MBP, respectively. Conclusion: Arterial stiffness in elastic arteries, but not in muscular arteries, increased significantly and progressively with age, and was more closely correlated to BP, plasma glucose and arterial thickness. © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins.

We have studied the process e+e− → nγ (n ≥ 2) at an average center-of-mass energy of 133 GeV using the L3 detector at LEP. For an integrated luminosity of 4.95 pb−1 we find one γγγγ(γ) final state with only hard photons. The rates of both γγγ and γγ events are consistent with QED expectations. The cross section of the reaction e+e− → γγ(γ) in the polar range 16° < θγ < 164° is measured to be 22.6 ± 2.2 pb. Decays into photons of narrow scalar resonances with masses between 90 and 130 GeV are not observed. The observation of the event with four energetic photons is consistent with QED although the kinematic configuration of the photons is atypical.

The inclusive semileptonic branching ratios b→eνX,μ νX,τ νX andνX have been measured at LEP with the L3 detector. The analysis is based on 2-jet hadronic Z decays obtained in the data collected between 1991 and 1992. Three separate event samples are analysed, containing electrons, muons and large missing energy (neutrinos), respectively. From the electron sample, we measure Br(b→eνX)=(10.89±0.20±0.51)% and, from the muon sample, Br(b→μ νX)=(10.82±0.15±0.59)%, where the first error is statistical and the second is systematic. From the missing energy sample, we measure Br(b→νX)=(23.08±0.77±1.24)%, assuming the relative semileptonic decay rates e:μ:τ=1:1:(0.25±0.05), according to theoretical expectations. From a combined analysis of all three samples and constraining the relative semileptonic rates, we measure Br(b→eνX)=Br(b→μ νX)=(10.68±0.11±0.46)%. Alternatively, we can remove the constraint on the relative semileptonic rates and measure Br(b→τ νX)=(1.7±0.5±1.1)%.

We present a study of the structure of hadronic events recorded by the L3 detector at center-of-mass energies of 130 and 136 GeV. The data sample corresponds to an integrated luminosity of 5 pb-1 collected during the high energy run of 1995. The shapes of the event shape distributions and the energy dependence of their mean values are well reproduced by QCD models. From a comparison of the data with resummed O(alpha_s^2) QCD calculations, we determine the strong coupling constant to be alpha_s(133 GeV) = 0.107 +/- 0.005(exp) +/- 0.006(theor).

A radiation monitoring system for the L3 experiment at the Large Electron Positron (LEP) collider is described. This system was installed in the L3 detector in April 1993. It provides information on the instantaneous and integrated radiation dose in the vicinity of the L3 silicon microvertex detector and time expansion chamber, and since April 1994 it has also provided trigger signals for the LEP beam dump in the case of large instantaneous dose rates in the L3 central tracking region.

The reaction \epem\ra\epem\gamma^*\gamma^*\ra\epem\kos\kos is studied with the L3 detector at LEP and the formation of the f_2\, \!\!\!'(1525) resonance is observed. For an integrated luminosity of 114 \pb, % \ collected over the years 1991-1994, 31\pm6 f_2\, \!\!\!' events are found. Their angular distribution is consistent with a pure helicity two. The radiative width times the branching ratio is measured to be \Gamma_{\gamma\gamma}(f_2\,\!\!\!')\times Br(f_2\ \!\!\!'\ra \k\bar{\k})=(0.093\pm 0.018\pm 0.022) keV. Only three events are found in the f_2(1270)-a_2(1320) mass region, consistent with destructive f_2-a_2 interference in the \kos\kos \ final state. The mixing angle of the tensor meson nonet is determined to be \theta=(29.4^{+1.4}_{-1.6})^\circ.

A search for the decays B d,s 0 → γγ in 2.95 million hadronic Z decays has been performed using the L3 detector at LEP. No candidates are found in the signal region and upper limits have been set on the branching ratios: Br(B d 0 → γ ) −5 and Br(B s 0 → γγ ) −5 at 90% CL. These are the first limits set on these exclusive rare decays.

The rates of decomposition of roots and root-derived materials are needed to assess the contribution of these materials to sequestration of organic carbon in soil. The objective of this study was to examine the kinetics of different forms of C in a Black Chernozem, with roots in situ under two barley cultivars, using 14C pulse-labeling and incubation methods. Plants were pulse-labeled (1 d) with 14CO2 25 d after emergence. Shoots were excised, and undisturbed soil cores containing the roots of a single plant were incubated at 20 °C for 80 d. The experiment involved two barley cultivars, with six replications at six sampling dates (days 0, 5, 10, 25, 40 and 80). The percentage of the labile components in roots of Abee (48%) was greater than that of Samson (39%), but the half lives of the labile components (0.693 k−1) of the roots were not significantly different between the two barley cultivars. The decomposition-rate constants for the resistant components of the roots were also not significantly different between the two barley cultivars. This indicated that the difference between the two barley cultivars in root decomposition rate could be explained by the difference in the ratios of the labile components to the resistant components. The average half life of 14C in roots was 41 d for Abee and 71 d for Samson. The amount of root 14C + soil 14C under Samson was higher than under Abee during the incubation period. These results supported our hypothesis that the cultivar that translocated more 14C-labeled carbon into roots and root-derived material has greater microbial respiration and greater C stabilization because a portion of added C remains in the soil after being transformed by microorganisms. Key words: Carbon kinetics, carbon sequestration, roots in situ, 14C pulse-labeling, Black Chernozem

Biological properties of soil are not only essential for the maintenance of soil fertility and the sustainability of the plant-soil ecosystems, but also indicators of land reclamation of contaminated or disturbed soils. This experiment involves two plants (barley and field pea) growing in four soils with different hydrocarbon contents. The objective was to study the effect of hydrocarbons on plant growth and microbial activity, and to evaluate the acid phosphatase activity as an indicator of reclamation of hydrocarbon-contaminated soils. Barley root mass decreased with the increase of the hydrocarbon content but field pea roots were not sensitive to the hydrocarbon content in this experiment. The hydrocarbon contamination reduced the plant growth but increased the microbial activity. The acid phosphatase activity was controlled by both plant root production and microbial activity, therefore it was not a good indicator of the reclamation of oil-contaminated soils.

Total and differential cross sections for the process e+e− → γγ(γ), and the total cross section for the process e+e− → γγγ, are measured at energies around 91 GeV using the data collected with the L3 detector from 1991 to 1993. We set lower limits, at 95% CL, on a contact interaction energy scale parameter Λ > 602 GeV, on the mass of an excited electron and on the QED cut-off parameters Λ+ > 149 GeV and Λ_ > 143 GeV. Upper limits are also set o branching fractions of Z decaying into γγ, π° and ηγ of 5.2 × 10−5, 5.2 × 10−5 and 7.6 × 10−5 respectively. The reactions e+e− → ℓ+ℓ−nγ (ℓ = e, μ, τ) are studied using the data collected from 1990 to 1994. The data are consistent with the QED expectations., Facultad de Ciencias Exactas

Nitrogen transformation is an important process in the bioremediation and revegetation of oil‐contaminated soils. Soils with various oil contents (from 0 to 60 mg hydrocarbon kg‐1 soil) were used in the experiment to study the effect of hydrocarbons on nitrogen transformation (net mineralization, nitrification and denitrification). The value of the net mineralization was positive in the uncontaminated soil but negative in the three oil contaminated soils. Hydrocarbons decreased the nitrification rate but increased the denitrification rate in soil. The residue (naphtha) remaining in SESR (solvent extraction soil remediation) soil had a greater effect on the nitrification process than the total hydrocarbon present. Water soluble hydrocarbon (dichloromethane extractable) content was positively correlated with denitrification rate in soil. The nitrogen transformation and cycling are controlled by not only the quantity but also the quality of the hydrocarbons in soil.

The production and utilization of root-derived C is fundamental to the functioning of ecosystems. The objectives of this experiment were to quantify the amount of root-released C produced by two barley (Hordeum vulgare L.) cultivars, to evaluate the direct and indirect effects of shoot C, root C and root length on the root-released C and to quantify the kinetics of the decomposition of root-released C in soil for two barley cultivars. Seedlings of two barley cultivars, Abee and Samson, were cultured in nutrient solution for 20 d and then pulse-labelled with 14C for 5 d. Samson released more C than Abee during the entire experimental period. Root length had the greatest direct effect on root-released C for the two barley cultivars. Kinetics analysis of the decomposition of root-released C added to soil showed that the labile components of the added material was 87.3% for Abee and 74.4% for Samson with half-lives of 4.3 d and 4.5 d, respectively. The half-lives of the resistant components of the root-released C added to soil and microbially-derived material were 37.7 d for Abee and 29.6 d for Samson, respectively. The amount of root-released C and its decomposition rate in soil varied with cultivars used. Key words: Root-released C, path analysis, direct effect, indirect effect, 14C, decomposition, Typic Cryoboroll

We have studied the four-fermion processes ee → eeee, eeμμ, eeττ, μμμμ, μμττ, eeqq and μμqq with the L3 detector at LEP. For an integrated luminosity of 36 pb-, corresponding to 960 000 hadronic Z decays, we find a total of 67 candidate events. The rate and kinematical distributions are found to be consistent with first order Monte Carlo calculations based on the Standard Model. No significant structure is seen in the dilepton invariant or recoil mass spectra. © 1994.
