Vocal evaluation of thyroplastic surgery in the treatment of unilateral vocal fold paralysis

Vocal function was assessed in 15 patients who received thyroplasty type I for the rehabilitation of unilateral vocal fold paralysis. The function was assessed by perceptual evaluation, voice intensity and frequency range profiles, and questionnaire. Goals of the study were to evaluate the efficacy of thyroplasty in improving the voice, to compare postoperative thyroplasty voices to normal voices, and to correlate objective measurements to the results of the questionnaire regarding satisfaction with the voice. Perceptual evaluations were performed by randomizing normal and thyroplasty voices on a recording tape. The voices on the tape were then rated by independent, blinded, trained listeners. The perceptual qualities of pitch, intonation, and loudness were not statistically different than normals; however, voice qualities of strain, breathiness, hoarseness, harshness, and unsteadiness were different than normals. Mean frequency range and mean intensity range were moderately to severely reduced from normals with a wide variation being present in the results. The correlation between the higher threshold phonation pressures and decreased intensity ranges found in some patients is discussed.
Hydrogen Peroxide Activates Cell Death and Defense Gene Expression in Birch1

The function of hydrogen peroxide (H2O2) as a signal molecule regulating gene expression and cell death induced by external stresses was studied in birch (Betula pendula). Ozone (O3),Pseudomonas syringae pv syringae(Pss), and wounding all induced cell death of various extents in birch leaves. This was temporally preceded and closely accompanied by H2O2 accumulation at, and especially surrounding, the lesion sites. O3 andPss, along with an artificial H2O2 producing system glucose (Glc)/Glc oxidase, elicited elevated mRNA levels corresponding to genes encoding reactive oxygen species detoxifying enzymes, Pal,Ypr10, and mitochondrial phosphate translocator 1. In addition to the regulation of gene expression, Glc/Glc oxidase also induced endogenous H2O2 production in birch leaves, accompanied by cell death that resembled O3 andPss damage. Wound-induced gene expression differed from that induced by O3 and Pss. Thus, it appears that at least two separate defense pathways can be activated in birch leaves by stress factors, even though the early H2O2 accumulation response is common among them all.
PLASMA BRAIN NATRIURETIC PEPTIDE MEASURED IN STABLE CONDITIONS IS RELATED TO MORTALITY IN FRAIL AND VERY OLD PATIENTS

CONCLUSIONS Alkaline reflux produces unique treatment challenges and can have negative consequences clinically and pathologically for patients’ postsurgical upper gastrointestinal tract but also more importantly for their quality of life. Traditional measures to facilitate gastric emptying, such as gastric tubes, pyloric drainage procedures, and motilityenhancing medications have limited efficacy and significant risks of morbidity. Coca-Cola and various soft drinks with acidic pH (see Table 1) are offered as a cheap, simple, and efficacious method of treatment.
Impairment of melibiose utilization in Streptococcus mutans serotype c gtfA mutants

The Streptococcus mutans serotype c gtfA gene encodes a 55-kilodalton sucrose-hydrolyzing enzyme. Analysis of S. mutans gtfA mutants revealed that the mutant strains were specifically impaired in the ability to use melibiose as a sole carbon source. S. mutans gtfA mutant strains synthesized less alpha-galactosidase activity inducible by raffinose than wild-type strains. Melibiose (an inducer in wild-type strains) failed to induce significant levels of alpha-galactosidase in the mutant strains. We hypothesize that melibiose use by S. mutans requires the interaction of the GtfA enzyme, or another gene product under the control of the gtfA promoter, with other gene product(s) involved in melibiose transport or hydrolysis.
High Frequency Trading and the 2008 Short Sale Ban

We examine the effects of high-frequency traders (HFTs) on liquidity using the September 2008 short sale-ban. To disentangle the separate impacts of short selling by HFTs and non-HFTs, we use an instrumental variables approach exploiting differences in the ban's cross-sectional impact on HFTs and non-HFTs. Non-HFTs’ short selling improves liquidity, as measured by bid-ask spreads. HFTs’ short selling has the opposite effect by adversely selecting limit orders, which can decrease liquidity supplier competition and reduce trading by non-HFTs. The results highlight that some HFTs’ activities are harmful to liquidity during the extremely volatile short-sale ban period.
Antimüllerian hormone levels are strongly associated with live-birth rates after assisted reproduction.

CONTEXT Previous studies have suggested that antimüllerian hormone (AMH) levels are positively associated with in vitro fertilization (IVF) outcome through their relationship with oocyte yield and not by reflecting oocyte or embryo quality. OBJECTIVE The aim was to investigate whether AMH levels are associated with pregnancy and live-birth rates and whether the results may also reflect qualitative aspects of oocytes and embryos. DESIGN The study was a prospective cohort study between April 2008 and June 2011. SETTING The study was done at a university-affiliated private infertility center. PATIENTS The study cohort consisted of 892 consecutive women undergoing 1230 IVF-intracytoplasmic sperm injection cycles. INTERVENTION(S) AMH levels, analyzed using the DSL ELISA kit, were statistically adjusted for repeated treatments and age and analyzed for associations with treatment outcome. MAIN OUTCOME MEASURES Pregnancy rates, live-birth rates, and stimulation outcome parameters were measured. RESULTS AMH was log-normally distributed with a mean (SD) of 2.3 (2.5) ng/mL. Live-birth rates per started cycle (mean [95% confidence interval]) increased log-linearly from 10.7% [7.2-14.1] for AMH < 0.84 ng/mL (25th percentile) to 30.8% [25.7-36.0] for AMH > 2.94 ng/mL (75th percentile), Ptrend < . 0001, being superior in women with polycystic ovaries. These findings were significant also after adjustments were made for age and oocyte yield. AMH was also associated with ovarian response variables and embryo scores. CONCLUSIONS AMH is strongly associated with live-birth rates after IVF-intracytoplasmic sperm injection. AMH may therefore serve as a prognostic factor for the chance of a pregnancy and live birth. Treatment outcome was superior in patients with polycystic ovaries. The findings also indicate that AMH may partially comprise information about oocyte quality.
Surgical Techniques

mined every 5 weeks: 5 weeks before AqT @re-aquatic therapy, control); weeks 0,5,10,15, and 20 ofAqT; and 5 and 10 weeks post-AqT (follow-up, recovery). Intervention: AqT was conducted by AqT-trained physical and occupational therapists (Women and Children's Hospital of Buffalo, NY) guiding children through specific movements in a warm-water pool (33.3-34.4"C), for 30-minute individual sessiodweek for 20 weeks, following a standardized, in-water protocol consisting of a 5-minute warm-up (Watsu relaxation techniques), 10-minutes of strengthening activities (isometric, isotonic, isokinetic), 5-minutes of child-specific stretching, and 10-minutes of functional activities targeting areas of individual need (e.g. rolling, walking, climbing). Facilitation methods used included proprioception neuromuscular facilitation, Bad Ragaz, Watsu, and Hallwick. Floatation devices and wrist/ankle weights were used, as needed. Measurementslmain results: From 5 weeks before AqT (control data) to before AqT (week 0), there was no difference in any GMFM score (Dimensions A-E) or GMFM Total Score. AqT (20 weeks) significantly improved all GMFM Dimensions, A-E, and GMFM Total Score, reported as percentage-change after 20 weeks ofAqT and percentage-change 10 weeks postAqT (Table I). Conclusions: AqT improved GMFM Dimensions (A-E) and Total Score, which persisted 10 weeks following therapy. AqT should be recommended as sports therapy in the rehabilitation of children with CI!
THE MOTION OF STRIGOMONAS ONCOPELTI

1. The movement of the flagellum of Strigomonas oncopelti has been studied using high-speed cinephotography. Waves usually pass along the flagellum from tip to base but under certain conditions waves are propagated from base to tip, reversing the direction of movement of the organism. 2. Increasing the viscosity of the medium reduces the frequency of beat while the shape of the wave remains unaltered. The variations in the wave parameters with increasing viscosity are consistent with a mechanically propagated wave. 3. Calculated values for Young9s modulus indicate that the membrane, the matrix, the nine peripheral fibrils or the central pair could act as the compressive elements needed to resist bending. The mechanism controlling the direction of wave propagation appears to lie in the membrane.
Performance Prediction of HPC Applications on Intel Processors

It is commonly the case that a small number of widely used applications make up a large fraction of the workload of HPC centers. Predicting the performance of important applications running on specific processors enables HPC centers to design best performing system configurations and to insure good performance for the most popular applications on new systems. In the analyses presented in this paper we use applications that are widely used on current open science HPC systems. We characterize the performance of these applications across a spectrum of modern processors and then create a mathematical model to predict their behavior on possible future processors. The hardware sensitivity studies required to build the predictive model are carried out in an HPC cloud resource with bare metal access, and we describe the process and advantages of this approach in detail. We define and discuss the mathematical model that we have designed and compare the predicted performance of these codes with the empirical results obtained in different chips. Finally, we also use the model to estimate the efficiency of future chips. The results indicate that the model is able to estimate the performance of these codes with a relatively small error across a fairly wide spectrum of chips.
EFECTOS DE LA TORTA DE SACHA INCHI (Plukenetia volubilis) PRECOCIDA SOBRE LA ESTRUCTURA HISTOLÓGICA DEL HIGADO, ILEON Y EL NIVEL DE PROTEÍNA TOTAL EN SANGRE DE POLLOS BROILER.

La torta de Plukenetia volubilis contiene altos niveles de proteina lo que lo convierte en un potencial insumo para las dietas de animales, sin embargo, su alto contenido en factores antinutricionales es una limitante para su uso. El objetivo del trabajo fue determinar el efecto de la torta de Plukenetia volubilis en los niveles de proteina serica y en la estructura histologica del higado e ileon. Para ello la torta de sacha inchi se proceso mediante coccion a 95o C por 5 minutos y luego de secado se preparo las dietas de acuerdo a las necesidades por fase de crecimiento. Dos grupos de pollos de 50 unidades cada uno y 1 dia de nacidos se alojaron en jaulas apropiadas hasta los 45 dias de edad. La proteina serica se determino mediante un espectrofotometro Boeco Germany S-22 UV/visible y reactivos WIENER LAB. (Argentina) en 15 muestras de sangre de cada uno de los grupos tomadas a los 7, 21 y 45 dias de edad. Los cortes histologicos fueron coloreados con hematoxilina-eosina. No se encontro variacion significativa en los niveles de proteina en suero sanguineo entre tratamientos (p≤0.05), asimismo la estructura de la mucosa del ileon no mostro cambios. Sin embargo el tejido hepatico mostro megalocitosis, asi mismo mostro proliferacion de los canaliculos biliares. De estos resultados se puede concluir que la torta de sacha inchi pre cocida incluido en un nivel de 6% de la dieta causa cambios importantes a nivel de tejido hepatico y no tiene efecto alguno tanto sobre los niveles de proteina total en suero sanguineo, asi como sobre la mucosa intestinal.

Product of shifted exponential variates and outage capacity of multicarrier systems

The probability density function and the cumulative distribution function of the product of shifted exponential variates are obtained in terms of the generalized upper incomplete Fox's H function. Using these new results, the exact outage capacity of multi carrier transmission through a slow Rayleigh fading channel is presented. Moreover, it is shown that analytical and simulation results are in perfect agreement.
Neuropathological investigation of cerebral white matter lesions caused by closed head injury

In order to ascertain whether there is widespread axonal disruption of cerebral white matter in the so‐called ‘diffuse axonal injury’ (DAI), a type of closed head injury, proposed by Adams et al. the author investigated his own cases clinicopathologically. Twenty‐six male autopsied cases of head injury, aged between 19 and 84, 15 of which had sustained road traffic accidents, were examined; the others were due to falling from heights and so on. The study group all belonged to non‐missile head injuries and included 12 cases of diffuse brain injury, as well as 14 cases of focal brain injury, according to the classification of Gennarelli et al. The survival time ranged from 2 h to 21 years. Formalin‐fixed brains were cut coronally so as to make paraffin‐embedded hemispheric sections. Then these sections were stained conventionally (HE, Bodian, Kluver‐Barrera and Holzer) and immunohistochemically (GFAP) to assess axonal decrease, myelin pallor and gliosis by the use of light microscopy. In the 13 chronic cases that died more than 1 month after the accidents, the intensities of gliosis, myelin pallor and axonal decrease tended to correlate with each other. In the 13 acute cases who died less than 1 month after their accident, the degree of axonal decrease in white matter seemed to correlate with the severity of myelin pallor. Regardless of types of trauma, however, axonal retraction balls, the so‐called hallmark of DAI, were found only with myelin pallor suggesting the presence of brain swelling after the injury. Therefore these findings indicate that it may be difficult to accept the notion of DAI, that is, the presence of axonal retraction balls without brain swelling. In addition, diffuse vascular injury (2 cases) as well as rarefaction of subcortical white matter (6 cases) were presented and their pathogenesis individually discussed based on a literature review.
A 0.5-V 74-dB SNDR 25-kHz Continuous-Time Delta-Sigma Modulator With a Return-to-Open DAC

A 0.5-V third-order one-bit fully-differential continuous-time DeltaSigma modulator is presented. The presented modulator architecture uses true low-voltage design techniques, and does not require internal voltage boosting or low-threshold devices. A return-to-open architecture that enables the ultra-low-voltage realization of return-to-zero signaling for the feedback DAC is proposed. The ultra-low-voltage operation is further enabled by a body-input gate-clocked comparator, and body-input operational transconductance amplifiers for the active-RC loop filter. Fabricated on a 0.18-mum CMOS process, the modulator achieves a peak SNDR of 74 dB in a 25 kHz bandwidth, and occupies an area of 0.6 mm2; the modulator core consumes 300 muW.
Epstein-Barr virus-infected cell line TCC36B derived from B lymphocytes infiltrating renal pelvis urothelial carcinoma.

UNLABELLED This study reports an initial analysis of an EBV-infected B cell line (TCC36B), established from an urothelial carcinoma (UC) lesion of the renal pelvis. MATERIALS AND METHODS Cytofluorometric and G-banding analyses were performed for phenotyping and cytogenetics. PCR was used to detect EBV DNA, and sequence analysis to investigate mutations and deletions of the latent membrane protein (LMP)-1 gene of EBV. RESULTS TCC36B cells proliferated in vitro and showed positivity for surface CD19, CD20, HLA-DR and IgG(λ), indicating that they belong to B-cells. Cytogenetic analysis showed 46,XX with a unique clonal abnormality of dup(2)(p13p25). EBV DNA was detected in TCC36B cells. Sequence analysis revealed a 30-bp deletion and 7 point mutations on the LMP-1 gene in TCC36B cells. CONCLUSION These results suggest the involvement of an EBV variant in the pathogenesis of UC. This cell line should thus facilitate further investigations on the aetiological role of EBV in urothelial cancer.
Effect of field edges on dispersal and distribution of colonizing stink bugs across farmscapes of the Southeast USA

Abstract Stink bugs (Heteroptera: Pentatomidae), including Nezara viridula (L.), Euschistus servus (Say), and Chinavia hilaris (Say), are economic pests in farmscapes where they move within and between closely associated crop and non-crop habitats. Thus, field edges in these farmscapes include not only crop-to-crop interfaces but also those edges adjoining non-crop habitats. We examined the influence of field edges on colonization of stink bugs in southeastern USA farmscapes composed of typical combinations of corn, peanut, and cotton. For E. servus and N. viridula, egg-to-adult development and presence of both sexes on all crops indicated that the crops served as reproductive plants. Adult C. hilaris were rarely found on corn and on crops associated with it, and they were present mainly in cotton in peanut–cotton farmscapes. Mature crop height was significantly higher for corn than for cotton and significantly higher for cotton over peanut, and an edge effect in dispersal of stink bugs into a crop was detected up to 4.6, 8.2, and 14.6 m from the crop-to-crop interface in corn, cotton, and peanut, respectively. These results suggest that stink bug dispersal into a crop decreases as crop height increases. The first stink bug-infested crop at the crop-to-crop interface was the most significant contributor of colonizing stink bugs to an adjacent crop. An edge effect in dispersal of stink bug adults was detected in corn next to non-woodlands and woodlands and in cotton adjacent to woodlands. Edge effects were never detected in side edges of peanut. Overall, our results indicate that both plant height and host plant suitability can influence edge-mediated dispersal of stink bugs at field edges.
Compliance of Cypriot nurses with standard precautions to avoid exposure to pathogens.

Standard Precautions have been introduced as a means to protect health professionals from exposure to pathogens. This study examines the extent of Cypriot nurses' compliance with the main aspects of Standard Precautions and explores the possible associations with the nurses' characteristics. Self-completed questionnaires that examined the frequency of the implementation of Standard Precautions were distributed to a convenience sample of 668 nurses.The response rate was 89.37%. The results showed inadequate compliance with Standard Precautions. Full compliance with all the main aspects of Standard Precautions was reported by only 9.1% of the participants. Male nurses and those who had not been exposed previously to pathogens reported better compliance, in comparison to female nurses and those who had been exposed previously. Nurses who had participated previously in an educational program about Standard Precautions reported a higher frequency of implementing them than those who had not participated. The nurses' age and frequency of the implementation of Standard Precautions were found to be significantly and positively correlated. The results can be used to enhance nurses' safety by focusing on areas of non-compliance.
Deceive Mouse-Dynamics-Based Authentication Model via Movement Simulation

Biometric security is one of the fundamental problems in user authentication. The authentication model based on mouse dy-namics and biometrics has been widely researched in recent years. However, the model security against potential attacks is largely ignored. In this paper, we propose a mouse movement simulation method to inspect the vulnerability of this authenti-cation technique. The authenticity of the mouse movement data generated by the simulation method is validated by five benchmark classifiers. Experimental results show the simula-tion method possesses a high authentication pass rate for most users. It indicates the proposed method can simulate real user mouse actions and the persuasive assumption that mouse be-havior is difficult to imitate might be too optimistic.
Acute myocardial infarction: the course of the illness following discharge from the coronary care unit. A description of the intermediate coronary care unit.

One hundred seventeen consecutive patients with acute transmural myocardial infarction were observed with intermittent ECG rhythm strip monitoring for 12 days after discharge from the coronary care unit (CCU). The patients were in a special room equipped for electrocardiography and for resuscitation if necessary. Here, a rhythm strip was recorded every four hours on all patients. This ECG strip was promptly examined by a physician. This system is referred to as the intermediate coronary care unit (ICCU). Fourteen patients had to be returned to the CCU, nine for arrhythmia and six for recurrent chest pain. There were three deaths in the ICCU; one each from A/V block and ventricular fibrillation, and one from congestive heart failure. One patient died from CHF after return to the CCU. Over this same length of time eight deaths had been anticipated.
Expression of the genes coding for the Escherichia coli integration host factor are controlled by growth phase, rpoS, ppGpp and by autoregulation

Transcriptional control of the himA and the himD/hip genes coding for the two subunits of the integration host factor (IHF) was investigated. The promoters for the two genes were identified by the use of primer extension and S1 analysis. Expression from both promoters was found to increase as the cells enter stationary phase. Mutation in rpoS, known to be induced upon entry to stationary phase, dramatically reduced the growth‐phase response of the himA P4 promoter but had only a small effect on the induction of the himD/hip promoter. The increased activity of both promoters required the presence of the rel4 and spoT genes, suggesting that ppGpp plays a major role in the response to stationary phase. An artificial increase in ppGpp in exponentially growing cells induced a rapid increase in himA P4 and himD/hip mRNA levels. Experiments with a mutant defective in rpoS showed that the response of the himA P4 promoter to high ppGpp levels was greatly reduced while that of himD/hip was only slightly affected. Therefore, it seems that different mechanisms involving RpoS and ppGpp regulate the growth‐phase response of the two promoters. We propose that the effect of ppGpp on himA P4 is mediated via RpoS whereas the himD/hip promoter is affected by ppGpp independently of RpoS.
