ObjectivesTo compare the velopharyngeal function, swallowing and speech of the conventional and modified radial forearm free flap (RFFF) for soft palate reconstruction.MethodsRetrospective clinical study. Twenty-eight patients who underwent oropharyngeal reconstruction with RFFF were divided into two groups: 10 patients had conventional folded RFFF and 18 patients underwent modified method.ResultsThe average speech intelligibility score in modified RFFF group was 8.0±2.4, and 6.2±2.2 in conventional RFFF group (P<0.05). The nasalance was 27.4±7.8% in modified group and 38.6±2.7% in conventional group during no nasal passage reading and 43.6±7.3% in modified group, 55.2±7.6% in conventional group during high nasal passage reading (P<0.05). The subjective swallowing functional score was 2.8 in modified group and 2.1 in conventional group.ConclusionThe speech assessment and nasalance demonstrate a more favorable outcome in modified group than conventional group

Bioavailable insulin-like growth factor-I as mediator of racial disparity in obesity-relevant breast and colorectal cancer risk among postmenopausal women

Bioavailable insulin-like growth factor (IGF)-I interacts with obesity and exogenous estrogen in a racial disparity in obesity-related cancer risk, yet their interconnected pathways are not fully characterized. We investigated whether circulating bioavailable IGF-I acted as a mediator of the racial disparity in obesity-related cancers such as breast and colorectal (CR) cancers and how obesity and estrogen use regulate this relationship

Increased Circulating Endothelial Microparticles and Carotid Atherosclerosis in Obstructive Sleep Apnea

Background and Purpose Endothelial impairment is a linking mechanism between obstructive sleep apnea (USA) and cardiovascular diseases Profiles of endothelial micropanicles (EMPs) and endothelial progenitor cells (EPCs) reflect the degree of endothelial impairment The aims of this study were to measure the levels of EMI`s and progenitor cells in USA, determine the correlations between these factors and USA severity and the deuce of atherosclerosis, and document any changes in these factors after therapy Methods Subjects with (n=82) and without (n=22) OSA were recruited prospectively We measured the number of colony-forming units (CM) in cell cultuie as the endothelial progenitor cell index, and the number of EMPs using flow cytometry with CD31 [platelet endothelial cell adhesion molecule (PECAM)], CD42 (platelet glycoprotem), annexm V, and CD62E (E-selectin) antibodies at baseline and Act 4-6 weeks of continuous positive airway pressure (CPA P) therapy Carotid int ima-media thickness (IMT) was regarded as a marker of atherosclerosis Results The levels of PECAM(+)CD42(-) (p<0 001). PECAM(+)annexin V(+) (p<0 001), and E-selectin(+) micropamcles (p=0 001) were higher in USA subjects than in non-USA subjects The number of CRJ did not differ between the two groups OSA severity independently predicted the levels of PECAM(+)CD42(-) (p=0 02) and PECA(+)annexin V(+) (p=0 004) Carotid IMT was correlated with USA severity (p<0 001), PECAM(+)CD42: (p=0 03), and PECAM(+)annexin (p=0 01) Neither USA severity nor carotid IMT was correlated with either the number of CFI) or E-selectin(+) CPAP therapy decreased the occurrence of E-selecte (p<0 001) in 21 of the USA subjects, but had no effect on the other micioparticles of the number CFU Conclusions USA led to the overproduction of EMI`s, which moderately correlated with USA seventy and the degree of atherosclerosis, and partly responded to therapy The endothelial impairment might contribute to future cardiovascular events J Clin Neurol 2010;6`89-98This research was supported by the Stem Cell Research Center of the 21st Century Frontier Research Program funded by the Ministry of Science and Technology, Republic of Korea (#SC4120).de Lima AMJ, 2010, RESPIRATION, V79, P370, DOI 10.1159/000227800Jung KH, 2009, ANN NEUROL, V66, P191, DOI 10.1002/ana.21681Ayers L, 2009, EUR RESPIR J, V33, P574, DOI 10.1183/09031936.00107408Akinnusi ME, 2009, AM J RESP CRIT CARE, V179, P328Christou K, 2009, SLEEP MED, V10, P87, DOI 10.1016/j.sleep.2007.10.011Barcelo A, 2008, THORAX, V63, P946, DOI 10.1136/thx.2007.093740Dorkova Z, 2008, CHEST, V134, P686, DOI 10.1378/chest.08-0556Robinson GV, 2008, THORAX, V63, P855, DOI 10.1136/thx.2007.088096Somers VK, 2008, CIRCULATION, V118, P1080, DOI 10.1161/CIRCULATIONAHA.107.189375Hirschi KK, 2008, ARTERIOSCL THROM VAS, V28, P1584, DOI 10.1161/ATVBAHA.107.155960Daniel L, 2008, NEPHROL DIAL TRANSPL, V23, P2129, DOI 10.1093/ndt/gfn029Martin K, 2008, LUNG, V186, P145, DOI 10.1007/s00408-008-9073-yAmabile N, 2008, AM J RESP CRIT CARE, V177, P1268, DOI 10.1164/rccm.200710-1458OCHeiss C, 2008, J AM COLL CARDIOL, V51, P1760, DOI 10.1016/j.jacc.2008.01.040Chu K, 2008, STROKE, V39, P1441, DOI 10.1161/STROKEAHA.107.499236Jelic S, 2008, CIRCULATION, V117, P2270, DOI 10.1161/CIRCULATIONAHA.107.741512Lee ST, 2008, NEUROLOGY, V70, P1510Bakouboula B, 2008, AM J RESP CRIT CARE, V177, P536, DOI 10.1164/rccm.200706-840OCLopez-Jimenez F, 2008, CHEST, V133, P793, DOI 10.1378/chest.07-0800de la Pena M, 2008, RESPIRATION, V76, P28, DOI 10.1159/000109643WON CHJ, 2008, P AM THORAC SOC, V5, P193Kloner RA, 2007, CIRCULATION, V116, P1306, DOI 10.1161/CIRCULATIONAHA.106.678375El Solh AA, 2007, AM J RESP CRIT CARE, V175, P1186, DOI 10.1164/rccm.200611-1598OCIBER C, 2007, AASM MANUAL SCORINGMONTSERRAT JM, 2007, AM J RESP CRIT CARE, V176, P6Pirro M, 2006, ARTERIOSCL THROM VAS, V26, P2530, DOI 10.1161/01.ATV.0000243941.72375.15Ryan S, 2006, AM J RESP CRIT CARE, V174, P824, DOI 10.1164/rccm.200601-066OCBoulanger CM, 2006, HYPERTENSION, V48, P180, DOI 10.1161/01.HYP.0000231507.00962.b5Arteaga RB, 2006, AM J CARDIOL, V98, P70, DOI 10.1016/j.amjcard.2006.01.054Robinson GV, 2006, EUR RESPIR J, V27, P1229, DOI 10.1183/09031936.06.00062805Werner N, 2005, NEW ENGL J MED, V353, P999Mezentsev A, 2005, AM J PHYSIOL-HEART C, V289, pH1106, DOI 10.1152/ajpheart.00265.2005Minoguchi K, 2005, AM J RESP CRIT CARE, V172, P625, DOI 10.1164/rccm.200412-1652OCMassa M, 2005, BLOOD, V105, P199, DOI 10.1182/blood-2004-05-1831Kim J, 2004, AM J RESP CRIT CARE, V170, P1108, DOI 10.1164/rccm.200404-519OCJy W, 2004, J THROMB HAEMOST, V2, P1842Tramontano AF, 2004, BIOCHEM BIOPH RES CO, V320, P34, DOI 10.1016/j.bbrc.2004.05.127Ip MSM, 2004, AM J RESP CRIT CARE, V169, P348, DOI 10.1164/rccm.200306.767OCBarba C, 2004, LANCET, V363, P157Bernal-Mizrachi L, 2003, AM HEART J, V145, P962, DOI 10.1016/S0002-8703(03)00103-0Jimenez JJ, 2003, THROMB RES, V109, P175, DOI 10.1016/S0049-3848(03)00064-1Hill JM, 2003, NEW ENGL J MED, V348, P593Preston RA, 2003, HYPERTENSION, V41, P211, DOI 10.1161/01.HYP.0000049760.15764.2DSabatier F, 2002, DIABETES, V51, P2840, DOI 10.2337/diabetes.51.9.2840El-Solh AA, 2002, CHEST, V121, P1541Boulanger CM, 2001, CIRCULATION, V104, P2649Barbe F, 2001, ANN INTERN MED, V134, P1015Chin K, 2000, AM J MED, V109, P562Lusis AJ, 2000, NATURE, V407, P233Ohga E, 1999, J APPL PHYSIOL, V87, P10YOUNG T, 1993, NEW ENGL J MED, V328, P1230JOHNS MW, 1991, SLEEP, V14, P540

Obesity and the Metabolic Syndrome in Korean Adolescents

This study evaluated the prevalence of metabolic syndrome and investigated its association with being overweight in Korean adolescents. Data were obtained from 1,393 students between 12 and 13 yr of age in a cross-sectional survey. We defined the metabolic syndrome using criteria analogous to the Third Report of the Adult Treatment Panel (ATP III) as having at least three of the following: fasting triglycerides ≥100 mg/dL; HDL <50 mg/dL; fasting glucose ≥110 mg/dL; waist circumference >75th percentile for age and gender; and systolic blood pressure >90th percentile for age, gender, and height. Weight status was assessed using the age- and gender-specific body mass index (BMI), and a BMI ≥85th percentile was classified as overweight. Of the adolescents, 5.5% met the criteria for the metabolic syndrome, and the prevalence increased with weight status; it was 1.6% for normal weight and 22.3% in overweight (p<0.001). In multivariate logistic regression analyses among adolescents, overweight status was independently associated with the metabolic syndrome (odds ratio, 17.7; 95% confidence interval, 10.0-31.2). Since childhood metabolic syndrome and obesity likely persist into adulthood, early identification helps target interventions to improve future cardiovascular health

Differences in Clinical Features According to Boryoung and Karp Genotypes of Orientia tsutsugamushi

Scrub typhus is an infectious disease caused by Orientia tsutsugamushi. The differences in virulence of O. tsutsugamushi prototypes in humans are still unknown. We investigated whether there are any differences in the clinical features of the Boryoung and Karp genotypes.Patients infected with O. tsutsugamushi, as Boryoung and Karp clusters, who had visited 6 different hospitals in southwestern Korea were prospectively compared for clinical features, complications, laboratory parameters, and treatment responses. Infected patients in the Boryoung cluster had significantly more generalized weakness, eschars, skin rashes, conjunctival injection, high albumin levels, and greater ESR and fibrinogen levels compared to the Karp cluster. The treatment response to current antibiotics was significantly slower in the Karp cluster as compared to the Boryoung cluster.The frequency of occurrence of eschars and rashes may depend on the genotype of O. tsutsugamushi

Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV

The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of √s = 7TeV corresponding to an integrated luminosity of 38 pb-1. Jets are reconstructed with the anti-kt algorithm with distance parameters R=0. 4 or R=0. 6. Jet energy and angle corrections are determined from Monte Carlo simulations to calibrate jets with transverse momenta pT≥20 GeV and pseudorapidities {pipe}η{pipe}<4. 5. The jet energy systematic uncertainty is estimated using the single isolated hadron response measured in situ and in test-beams, exploiting the transverse momentum balance between central and forward jets in events with dijet topologies and studying systematic variations in Monte Carlo simulations. The jet energy uncertainty is less than 2. 5 % in the central calorimeter region ({pipe}η{pipe}<0. 8) for jets with 60≤pT<800 GeV, and is maximally 14 % for pT<30 GeV in the most forward region 3. 2≤{pipe}η{pipe}<4. 5. The jet energy is validated for jet transverse momenta up to 1 TeV to the level of a few percent using several in situ techniques by comparing a well-known reference such as the recoiling photon pT, the sum of the transverse momenta of tracks associated to the jet, or a system of low-pT jets recoiling against a high-pT jet. More sophisticated jet calibration schemes are presented based on calorimeter cell energy density weighting or hadronic properties of jets, aiming for an improved jet energy resolution and a reduced flavour dependence of the jet response. The systematic uncertainty of the jet energy determined from a combination of in situ techniques is consistent with the one derived from single hadron response measurements over a wide kinematic range. The nominal corrections and uncertainties are derived for isolated jets in an inclusive sample of high-pT jets. Special cases such as event topologies with close-by jets, or selections of samples with an enhanced content of jets originating from light quarks, heavy quarks or gluons are also discussed and the corresponding uncertainties are determined. © 2013 CERN for the benefit of the ATLAS collaboration

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

Search for the neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at root s=7 TeV with the ATLAS detector

A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7TeV recorded with the ATLAS detector at the Large Hadron Collider. The data were recorded in 2011 and correspond to an integrated luminosity of 4.7 fb-1 to 4.8 fb-1. Higgs boson decays into oppositely-charged muon or τ lepton pairs are considered for final states requiring either the presence or absence of b-jets. No statistically significant excess over the expected background is observed and exclusion limits at the 95% confidence level are derived. The exclusion limits are for the production cross-section of a generic neutral Higgs boson, φ, as a function of the Higgs boson mass and for h/A/H production in the MSSM as a function of the parameters mA and tan β in the mhmax scenario for mA in the range of 90GeV to 500 GeV.

Search for R-parity-violating supersymmetry in events with four or more leptons in sqrt(s) =7 TeV pp collisions with the ATLAS detector

A search for new phenomena in final states with four or more leptons (electrons or muons) is presented. The analysis is based on 4.7 fb−1 of $\sqrt{s}=7\;\mathrm{TeV}$ proton-proton collisions delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in two signal regions: one that requires moderate values of missing transverse momentum and another that requires large effective mass. The results are interpreted in a simplified model of R-parity-violating supersymmetry in which a 95% CL exclusion region is set for charged wino masses up to 540 GeV. In an R-parity-violating MSUGRA/CMSSM model, values of m 1/2 up to 820 GeV are excluded for 10 < tan β < 40
