Abstract: © 2015 American College of Veterinary Internal Medicine. Background: An intravenous (IV) overdose of pentobarbital sodium is the most commonly used method of euthanasia in veterinary medicine. However, this compound is not available in many countries or rural areas resulting in usage of alternative methods such as intrathecal lidocaine administration after IV anesthesia. Its safety and efficacy as a method of euthanasia have not been investigated in the horse. Hypothesis/Objectives: To investigate changes in mean arterial blood pressure and electrical activity of the cerebral cortex, brainstem, and heart during intrathecal administration of lidocaine. Our hypothesis was that intrathecal lidocaine affects the cerebral cortex and brainstem before affecting cardiovascular function. Animals: Eleven horses requiring euthanasia for medical reasons. Methods: Prospective observational study. Horses were anesthetized with xylazine, midazolam, and ketamine; and instrumented for recording of electroencephalogram (EEG), electrooculogram (EOG), brainstem auditory evoked response (BAER), and electrocardiogram (ECG). Physical and neurological (brainstem reflexes) variables were monitored. Mean arterial blood pressure was recorded throughout the study. Results: Loss of cerebro-cortical electrical activity occurred up to 226 seconds after the end of the infusion of lidocaine solution. Cessation of brainstem function as evidenced by a lack of brainstem reflexes and disappearance of BAER occurred subsequently. Undetectable heart sounds, nonpalpable arterial pulse, and extremely low mean arterial blood pressure supported cardiac death; a recordable ECG was the last variable to disappear after the infusion (300-1,279 seconds). Conclusions and Clinical Importance: Intrathecal administration of lidocaine is an effective alternative method of euthanasia in anesthetized horses, during which brain death occurs before cardiac death.

Abstract: Background Immune-mediated myositis (IMM) is a cause of rhabdomyolysis, stiffness, and muscle atrophy predominantly affecting Quarter horses. Limited information is available with regard to outcome, prognostic indicators, and associations with concurrent diseases. Hypothesis/Objectives To report outcomes and associations between outcome and clinical and laboratory parameters, and presence of concurrent illness. Animals Sixty-eight horses; 52 Quarter horses and related breeds and 16 other breeds. Methods Retrospective cohort study (1991–2014). Medical records of horses with histological diagnosis of IMM were reviewed. Data recovery included signalment, laboratory variables, therapy, and outcome. Logistic regression was used to quantify the association between potential prognostic factors and survival to discharge. Results Quarter horses were younger (mean < 4 years, range 3 months–21 years) than other breeds (mean < 10 years, range 1–23 years). Pathogens causing concurrent or recent infection included S. equi equi, S. equi zooepidemicus, C. pseudotuberculosis, Anaplasma phagocytophilum, herpes virus-1, and influenza. The most common clinical signs consisted of rapidly progressive diffuse symmetrical muscle atrophy (80%), stiff gait (74%), and fever (44%). All horses that received medical therapy immediately upon admission survived to discharge (survival proportion = 87%). Leucocytosis was a common finding (60%). Horses with concurrent fever and other illness had a poor prognosis for hospital discharge. Conclusions and Clinical Importance Horses with IMM can have a favorable outcome. Horses with concurrent fever and another illness had decreased probability of survival to discharge.

Abstract: Background Auditory loss is a common deficit in horses with temporohyoid osteoarthropathy (THO), however, recovery of function is unknown. Hypothesis/Objectives To investigate neurologic function with emphasis in audition in horses with THO after treatment. To describe anatomical alterations of the petrous temporal bone that might result in auditory loss. Animals Twenty-four horses with a clinical diagnosis of THO. Methods Prospective study. A brainstem auditory evoked response (BAER) study was done as part of the criteria for inclusion in horses with a clinical diagnosis of THO from the years of 2005 to 2014. Physical and neurologic status and BAER findings were recorded. Brainstem auditory evoked response variables were compared by using Wilcoxon sign test. Fisher's exact test was also used. Significance was set at P < 0.05. Results The most common signs included auditory loss (100% of horses), vestibular and facial nerve dysfunction (83%), and exposure ulcerative keratitis (71%). Concurrent left laryngeal hemiparesis was observed in 61% of horses through endoscopy. Auditory dysfunction was bilateral in 50% of the cases (complete and partial), and unilateral affecting more commonly the right ear (R = 8, L = 4). Short- and long-term follow-up revealed persistent auditory loss in all horses based on abnormal response to sound, and further confirmed through a BAER in 8 horses. Conclusions and Clinical Importance Auditory dysfunction appears to be a permanent neurologic deficit in horses diagnosed with THO despite overall neurologic improvement.

Digital EEG with video and quantitative EEG (qEEG) were recorded after the administration of one of the 2 anesthetics, isoflurane or halothane, at 3 alveolar doses (1.2, 1.4 and 1.6 MAC). Segments of EEG during controlled ventilation (CV), spontaneous ventilation (SV), and with peroneal nerve stimulation (ST) at each MAC multiple for each anesthetic were selected, analyzed, and compared. Multiple non-EEG measurements were also recorded.ResultsSpecific raw EEG findings were indicative of changes in the depth of anesthesia. However, there was considerable variability in EEG between horses at identical MAC multiples/conditions and within individual horses over segments of a given epoch. Statistical significance for qEEG variables differed between anesthetics with bispectral index (BIS) CV MAC and 95% spectral edge frequency (SEF95) SV MAC differences in isoflurane only and median frequency (MED) differences in SV MAC with halothane only.Conclusions and clinical importanceUnprocessed EEG features (background and transients) appear to be beneficial for monitoring the depth of a particular anesthetic, but offer little advantage over the use of changes in mean arterial pressure for this purpose.

Abstract: Background: Botulism is a potentially fatal paralytic disorder for which definitive diagnosis is difficult. Objectives: To determine if repetitive stimulation of the common peroneal nerve will aid in the diagnosis of botulism in foals. Animals: Four control and 3 affected foals. Methods: Validation of the test in healthy foals for its comparison in foals with suspected botulism. Controls were anesthetized and affected foals were sedated to avoid risks of anesthesia. The common peroneal nerve was chosen for its superficial location and easy access. Stimulating electrodes were placed along the common peroneal nerve. For recording, the active and reference electrodes were positioned over the midpoint and distal end of the extensor digitorum longus muscle, respectively. Repeated supramaximal stimulation of the nerve was performed utilizing a range of frequencies (1–50 Hz). Data analysis consisted of measuring the amplitude and area under the curve for each M wave and converting these values into percentages of decrement or increment based on the comparison of subsequent potentials to the initial one (baseline) within each set. Results: A decremental response was seen at all frequencies in control foals. Decremental responses also were observed in affected foals at low frequencies. An incremental response was seen in all affected foals at 50 Hz. Conclusions and Clinical Importance: Decreased baseline M wave amplitudes with incremental responses at high rates are supportive of botulism. Repetitive nerve stimulation is a safe, simple, fast, and noninvasive technique that can aid in the diagnosis of suspected botulism in foals.

Abstract: Fifteen horses with pituitary pars intermedia dysfunction were studied. The horses were of various breeds and between 15 and 28 years of age. Control horses matched for breed and age were studied for comparison. Evaluations included complete blood cell count and serum biochemical analysis, electromyography, and gluteus medius muscle biopsies for histochemical, morphometric, and ultrastructural analysis. No differences were found between groups of horses on routine laboratory analysis or electromyography. We demonstrated that muscle wasting in diseased horses was the result of atrophy of types 2A and 2B muscle fibers and loss of type 2B myofibers. Mild non-specific non-inflammatory myopathic alterations such as myofiber size variation, internal nuclei, perimysial, endomysial and sarcoplasmic fat accumulation were observed. At the ultrastructural level, subsarcolemmal mitochondrial accumulation and increased lipid droplets were evident. Similar to other species, this study confirmed atrophy of type 2 fibers as the cause of muscle mass loss in horses with Cushing's disease.

Abstract: Background Reports of the use of brainstem auditory evoked response (BAER) as a diagnostic modality in foals have been limited. Hypothesis/Objectives To describe BAER findings and associated causes of hearing loss in foals. Animals Study group 18 foals (15 neonatal, 3 nonneonatal), control group (5 neonatal foals). Methods Retrospective. BAER records from the Clinical Neurophysiology Laboratory were reviewed from the years of 1982 to 2013. Peak latencies, amplitudes, and interpeak intervals were measured when visible. Clinical data were extracted from the medical records. Foals were grouped under disease categories. Descriptive statistics were performed. Results Ten neonatal foals had complete absence of BAER bilaterally and 5 had findings within reference range. Abnormalities were associated with common neonatal disorders such as sepsis, neonatal encephalopathy, neonatal isoerythrolysis, and prematurity. BAER loss also was observed in foals with specific coat color patterns such as completely or mostly white with blue irides or lavender with pale yellow irides. An American Miniature foal with marked facial deformation also lacked BAER bilaterally. One nonneonatal foal with an intracranial abscess had no detectable BAER peaks bilaterally, and 2 older foals, 1 with presumed equine protozoal myeloencephalitis and the other with progressive scoliosis and ataxia, had BAER within normal limits. Conclusions and Clinical Importance In neonatal foals, BAER deficits commonly are complete and bilateral, and associated with common neonatal disorders and certain coat and eye color patterns. Sepsis, hypoxia, bilirubin toxicity, and prematurity should be investigated as potential causes of auditory loss in neonatal foals.

Abstract: Author(s): Aleman, M; Dickinson, PJ; Williams, DC; Sturges, BK; LeCouteur, RA; Vernau, KM; Shelton, GD | Abstract: BackgroundReports of motor polyneuropathies in young cats are scarce. Further, in-depth electrophysiologic evaluation to confirm a motor polyneuropathy in young cats of various breeds other than 2 Bengal cats is lacking.Hypothesis/objectivesTo confirm a motor polyneuropathy in young cats of various breeds.AnimalsFive young cats with heterogenous chronic or relapsing episodes of weakness.MethodsRetrospective case series. Cats were presented for evaluation of generalized neuromuscular disease and underwent electrophysiologic examination including electromyography, nerve conduction, and repetitive nerve stimulation. Minimum database and muscle and nerve biopsy analyses were carried out. Descriptive statistics were performed.ResultsDisease onset was at 3 months to 1 year of age and in 5 breeds. The most common clinical sign (5 of 5 cats) was weakness. Additional neurologic deficits consisted of palmigrade and plantigrade posture (4/4), low carriage of the head and tail (4/4), and variable segmental reflex deficits (5/5). Motor nerve conduction studies were abnormal for the ulnar (4/4), peroneal (5/5), and tibial (2/2) nerves (increased latencies, reduced amplitudes, slow velocities). A marked decrement was observed on repetitive nerve stimulation of the peroneal nerve in 3 cats for which autoimmune myasthenia gravis was ruled out. All sensory nerve conduction studies were normal. Histologic evaluation of muscle and nerve biopsies supported heterogenous alterations consistent with motor polyneuropathy with distal nerve fiber loss.Conclusions and clinical importanceHeterogenous motor polyneuropathies should be considered in young cats of any breed and sex that are presented with relapsing or progressive generalized neuromuscular disease.

14. Membrane Cholesterol Modulates Serotonin Transporter Activity

Abstract: The synaptic actions of the neurotransmitter serotonin are terminated by a selective high-affinity reuptake mediated by the serotonin transporter (SERT). To gain insight into the modulation of the functional properties of this integral membrane protein by cholesterol, a main component of the lipid bilayer, we stably expressed the rat SERT in human embryonic kidney 293 cells and, upon altering the cholesterol content of these cells by different means, analyzed SERT activity. Depletion of the level of membrane cholesterol by treatment with either the cholesterol chelating agent methyl-beta-cyclodextrin (MbetaCD), cholesterol oxidase, or the cholesterol-binding fluorochrome filipin resulted in a decrease in SERT activity due to both a loss of affinity of substrate and ligand binding and a concomitant reduction of the maximal transport rate. In cholesterol-depleted membranes, cholesterol levels could be restored to those found in untreated membranes by incubation of the membranes with an MbetaCD-cholesterol complex, which correlated with a reversal of the cholesterol depletion-mediated decrease in the level of high-affinity binding. This was not the case when other steroids, such as ergosterol, 5-cholestene, or pregnenolone, were substituted into cholesterol-depleted membranes. These results suggest that membrane cholesterol modulates the functional properties of the SERT by specific molecular interactions which are needed to stabilize the transporter in its optimally active form.

Abstract: The parity violation parameters Ab and Ac of the Zb anti-b and Zc anti-c couplings have been measured directly, using the polar angle dependence of the Z0-pole polarized cross sections. Bottom and charmed hadrons were tagged via semileptonic decays. Both the muon and electron identification algorithms take advantage of new multivariate techniques, incorporating for the first time information from the SLD Cerenkov Ring Imaging Detector. Based on the 1993-95 SLD sample of 150,000 Z0 decays produced with highly polarized electron beams, we measure: Ab = 0.910 ± 0.068(stat) ± 0.037(syst) Ac = 0.642 ± 0.110(stat) ± 0.063(syst).

Abstract: We present a direct measurement of the parity-violating asymmetry A{sub b} in the Z{sup 0} to b anti-b coupling using a new technique to distinguish the b and anti-b quarks using charged kaons from B decays. The Z{sup 0} bosons are produced in e{sup +}e{sup -} collisions at the SLC with longitudinally polarized electrons. b anti-b events are selected using a secondary vertex mass tag and A{sub b} is determined from the left-right forward-backward asymmetry. From the 1994-1995 data sample, selected from 100,000 hadronic Z{sup 0} decays, we obtain A{sub b} = 0.855 {+-} 0. 088{sub stat} {+-} 0.102{sub sys}.

Abstract: We report on the results from a beam test of a binary silicon strip system proposed for ATLAS. The data were collected during the H8 beam test at CERN in 1995 and at a beam test at KEK in 1996. The binary modules tested had been assembled from silicon micro-strip detectors of different layout and from front-end electronics chips of different architecture. The efficiency, noise occupancy, and position resolution were determined as a function of the threshold setting for various bias voltages and angles of incidence. Interstrip effects were also evaluated using a high resolution telescope. The performance of a prototype detector module irradiated to a fiuence of 1.2 × 10 14 p/cm 2 is also characterized.

Abstract: We have measured the $B$ hadron energy distribution in ${Z}^{0}$ decays using a sample of semileptonic $B$ decays recorded in the SLD experiment at SLAC. The energy of each tagged $B$ hadron was reconstructed using information from the lepton and a partially reconstructed charm-decay vertex. We compared the scaled energy distribution with several models of heavy quark fragmentation. The average scaled energy of primary $B$ hadrons was found to be $〈{x}_{{E}_{B}}〉=0.716\ifmmode\pm\else\textpm\fi{}0.011(\mathrm{stat}{)}_{\ensuremath{-}0.022}^{+0.021}(\mathrm{syst})$.

Abstract: A small electromagnetic sampling calorimeter, installed in the ZEUS experiment in 1995, significantly enhanced the acceptance for very low x and low Q 2 inelastic neutral current scattering, e+p → e+X, at HERA. A measurement of the proton structure function F2 and the total virtual photon-proton ( γ ∗ p ) cross-section is presented for 0.11 ≤ Q 2 ≤ 0.65 GeV2 and 2 × 10−6 ≤ x ≤ 6 × 10−5, corresponding to a range in the γ ∗ p c.m. energy of 100 ≤ W ≤ 230 GeV. Comparisons with various models are also presented.

Abstract: We present a new measurement of the tau neutrino helicity, hnu and the tau Michel parameters rho, eta, xi and the product delta xi. The analysis exploits the highly polarized SLC electron beam to extract these quantities directly from a measurement of the tau decay spectra, using the 1993-1995 SLD data sample of 4328 e+e- --> Z0 --> tau+tau- events. From the decays tau --> pi nu(tau) and tau --> rho nu(tau) we obtain a combined value hnu=-0.93+/-0.10+/-0.04. The leptonic decay channels yield combined values of rho=0.72+/-0.09+/-0.03, xi=1.05+/-0.35+/-0.04 and delta xi=0.88+/-0.27+/-0.04.

Abstract: We present evidence for leading particle production in hadronic decays of the Z{sup 0} boson to light-flavor jets. A polarized electron beam was used to tag quark and antiquark jets, and a vertex detector was employed to reject heavy-flavor events. Charged hadrons were identified with a Cherenkov ring imaging detector. In the quark jets, more high-momentum p, L, K{sup -}, and {bar K}{sup *0} were observed than their antiparticles, and vice versa for antiquark jets, providing direct evidence that the higher-momentum particles in jets are more likely to carry the primary quark or antiquark from the Z{sup 0} decay, and that s{bar s} production is suppressed in fragmentation. {copyright} {ital 1997} {ital The American Physical Society}

Abstract: We present a new measurement of the left-right cross section asymmetry (ALR) for Z boson production by e+e- collisions. The measurement was performed at a center-of-mass energy of 91.28 GeV with the SLD detector at the SLAC Linear Collider (SLC). The luminosity-weighted average polarization of the SLC electron beam was (77.23+-0.52)%. Using a sample of 93,644 Z decays, we measure the pole-value of the asymmetry, ALR0, to be 0.1512+-0.0042(stat.)+-0.0011(syst.) which is equivalent to an effective weak mixing angle of sin**2(theta_eff)=0.23100+-0.00054(stat.)+-0.00014(syst.).

Abstract: We present the first measurement of the left-right charge asymmetry ${A}_{Q}^{\mathrm{obs}}$ in hadronic $Z$ boson decays. This was performed at ${E}_{\mathrm{c}.\mathrm{m}.}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}91.27\mathrm{GeV}$ with the SLD at the SLAC Linear Collider with a polarized electron beam. Using 89 838 events we obtain ${A}_{Q}^{\mathrm{obs}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.225\ifmmode\pm\else\textpm\fi{}0.056\ifmmode\pm\else\textpm\fi{}0.019$, which leads to a measurement of the electron left-right asymmetry parameter, ${A}_{e}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.162\ifmmode\pm\else\textpm\fi{}0.041\ifmmode\pm\else\textpm\fi{}0.014$, and ${sin}^{2}{\ensuremath{\theta}}_{W}^{\mathrm{eff}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.2297\ifmmode\pm\else\textpm\fi{}0.0052\ifmmode\pm\else\textpm\fi{}0.0018$. Also, the ${A}_{Q}^{\mathrm{obs}}$ measurement combined with the left-right cross section asymmetry determines ${A}_{e}$ independent of the value of the electron-beam polarization.

Abstract: We report on a measurement of CP-violating asymmetries (A{sub CP}) in the Cabibbo-suppressed D{sup 0} {yields} {pi}{sup +}{pi}{sup -} and D{sup 0} {yields} K{sup +}K{sup -} decays reconstructed in a data sample corresponding to 5.9 fb{sup -1} of integrated luminosity collected by the upgraded Collider Detector at Fermilab. We use the strong decay D*{sup +} {yields} D{sup 0}{pi}{sup +} to identify the flavor of the charmed meson at production and exploit CP-conserving strong c{bar c} pair-production in p{bar p} collisions. High-statistics samples of Cabibbo-favored D{sup 0} {yields} K{sup -}{pi}{sup +} decays with and without a D*{sup {+-}} tag are used to correct for instrumental effects and significantly reduce systematic uncertainties. We measure A{sub CP}(D{sup 0} {yields} {pi}{sup +}{pi}{sup -}) = (+0.22 {+-} 0.24(stat) {+-} 0.11 (syst))% and A{sub CP}(D{sup 0} {yields} K{sup +}K{sup -}) = (-0.24 {+-} 0.22 (stat) {+-} 0.09 (syst))%, in agreement with CP conservation. These are the most precise determinations from a single experiment to date. Under the assumption of negligible direct CP violation in D{sup 0} {yields} {pi}{sup +}{pi}{sup -} and D{sup 0} {yields} K{sup +}K{sup -} decays, the results provide an upper limit to the CP-violating asymmetry in D{sup 0} mixing, |A{sub CP}{sup ind}(D{sup 0})| < 0.13% at the 90% confidence level.

Abstract: The e{sup +}e{sup -}{yields}pp cross section is determined over a range of pp masses, from threshold to 4.5 GeV/c{sup 2}, by studying the e{sup +}e{sup -}{yields}pp{gamma} process. The data set corresponds to an integrated luminosity of 232 fb{sup -1}, collected with the BABAR detector at the PEP-II storage ring, at an e{sup +}e{sup -} center-of-mass energy of 10.6 GeV. The mass dependence of the ratio of electric and magnetic form factors, G{sub E}/G{sub M}, is measured for pp masses below 3 GeV/c{sup 2}; its value is found to be significantly larger than 1 for masses up to 2.2 GeV/c{sup 2}. We also measure J/{psi}{yields}pp and {psi}(2S){yields}pp branching fractions and set an upper limit on Y(4260){yields}pp production and decay.

Abstract: Background Idiopathic headshaking (HSK) in horses is a distressing disorder in which the etiology and pathophysiology are unknown. Hypothesis Differences in sensory function of the trigeminal nerve exist between healthy and affected horses. Animals Six healthy mature geldings and 6 mature geldings with idiopathic HSK. Methods Prospective study. Sensory nerve action and somatosensory evoked potentials studies were performed. The stimulus site comprised the gingival mucosa dorsal to the maxillary canine. A pair of recording electrodes was placed along the sensory pathway of the trigeminal complex at the infraorbital nerve (R1), maxillary nerve (R2), spinal tract of trigeminal (R3), and somatosensory cortex (R4). Sensory nerve action potential latency (ms), amplitude (μV), duration (ms), area under the curve (μVms), and conduction velocity (m/s) were calculated. Results Threshold for activation of the infraorbital branch of the trigeminal nerve was significantly different between 5 affected (≤5 mA) and 6 control horses (≥10 mA). After initiation of an action potential, there were no differences in all parameters measured and no differences between left and right sides. A horse with seasonal HSK tested during a time of no clinical manifestations showed a threshold for activation similar to control horses. Conclusions and Clinical Importance This study confirms involvement of the trigeminal nerve hyperexcitability in the pathophysiology of disease. Further, results might support a functional rather than a structural alteration in the sensory pathway of the trigeminal complex that can be seasonal. The horse could serve as a natural animal model for humans with idiopathic trigeminal neuralgia.

Abstract: We present measurements of Rb using the SLD at the SLC. The analyses use 2D and 3D impact parameter tags and a displaced 3D vertex tag which all exploit the small size and stability of the e+e- interaction point and the precision 3D CCD pixel vertex detector to achieve high bb¯-tagging efficiencies and purities. The combined measurement yields Rb=0.229±0.011 and is consistent with standard model predictions.

Abstract: We present the first measurement of the correlation between the {ital Z}{sup 0} spin and the event-plane orientation in polarized {ital Z}{sup 0} decays into three jets in the SLAC Linear Collider Large Detector experiment at SLAC utilizing a longitudinally polarized electron beam. The {ital CP}-even and {ital T}-odd triple product {ital {rvec S}}{sub {ital Z}}{center_dot}({ital {rvec k}}{sub 1}{times}{ital {rvec k}}{sub 2}), formed from the two fastest jet momenta {ital {rvec k}}{sub 1} and {ital {rvec k}}{sub 2} and the {ital Z}{sup 0} polarization vector {ital {rvec S}}{sub {ital Z}}, is sensitive to physics beyond the standard model. We measure the expectation value of this quantity to be consistent with zero and set 95% C.L. limits of {minus}0.022{lt}{beta}{lt}0.039 on the correlation. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

Abstract: We report for the first time on the performance of the Central Drift Chamber (CDC) of the Stanford Linear Collider Large Detector (SLD), which has been recording data since 1992. The low mass of the chamber and the use of a gas characterized by both a low drift velocity and low diffusion constant help to minimize the drift-distance measurement errors. We describe some of the calibrations and corrections applied to the data, and report on the resolutions achieved thus far. We measure an intrinsic drift resolution of 55-110 /spl mu/m in the region of uniform field. Analysis of the full drift-pulse waveform allows for efficient double-hit resolution of about 1 mm. Momentum resolution is characterized by the formula (dp/sub t//p/sub t//sup 2/)/sup 2/=0.0050/sup 2/+(0.010/p/sub t/)/sup 2/, where p/sub t/ is expressed in units of GeV/c. Used in conjunction with the SLD vertex detector, the CDC permits measurements of impact parameters of high-momentum tracks to the level of 10 /spl mu/m in the r-/spl phi/ plane and 36 /spl mu/m in the r-z plane. A resolution of 6.4% is achieved in the measurement of dE/dx for the electrons in Bhabha scattering events. >

Abstract: We report on a measurement of the proton structure function F 2 in the range 3.5×10-5≤x≤4×10-3 and 1.5 GeV2≤Q 2≤15GeV2 at the ep collider HERA operating at a centre-of-mass energy of √s=300GeV. The rise of F 2 with decreasing x observed in the previous HERA measurements persists in this lower x and Q 2 range. The Q 2 evolution of F 2, even at the lowest Q 2 and x measured, is consistent with perturbative QCD. © 1996 Springer-Verlag.

Abstract: We present a direct measurement of {ital A}{sub {ital c}}=2{ital v}{sub {ital c}}{ital a}{sub {ital c}}/({ital v}{sup 2}{sub {ital c}}+{ital a}{sup 2}{sub {ital c}}) from the left-right forward-backward asymmetry of {ital D}{sup *}+ and {ital D}{sup +} mesons in {ital Z}{sup 0} events produced with the longitudinally polarized SLAC Linear Collider beam. These {ital Z}{sup 0}{r_arrow}{ital c} over bar events are tagged on the basis of event kinematics and decay topology from a sample of hadronic {ital Z}{sup 0} decays recorded by the SLAC Large Detector. We measure {ital A}{sup 0}{sub {ital c}} = 0.73 {plus_minus} 0.22(stat) {plus_minus} 0.10(syst). {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

Abstract: We report a measurement of the average {ital B} hadron lifetime using data collected with the SLD detector at the SLAC Linear Collider in 1993. An inclusive analysis selected three-dimensional vertices with {ital B} hadron lifetime information in a sample of 50{times}10{sup 3} {ital Z}{sup 0} decays. A lifetime of 1.564{plus_minus}0.030(stat){plus_minus}0.036(syst) ps was extracted from the decay length distribution of these vertices using a binned maximum likelihood method. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

Abstract: We have compared a new QCD calculation by Clay and Ellis of energy-energy correlations (EEC`s) and their asymmetry (AEEC`s) in {ital e}{sup +}{ital e}{sup {minus}} annihilation into hadrons with data collected by the SLD experiment at SLAC. From fits of the new calculation, complete at {ital O}({alpha}{sub {ital s}}{sup 2}), we obtained {alpha}{sub {ital s}}({ital M}{sub {ital Z}}{sup 2})=0.1184{plus_minus}0.0031(expt){plus_minus}0.0129(theory) (EEC) and {alpha}{sub {ital s}}({ital M}{sub {ital Z}}{sup 2})=0.1120{plus_minus}0.0034(expt){plus_minus}0.0036(theory) (AEEC). The EEC result is significantly lower than that obtained from comparable fits using the {ital O}({alpha}{sub {ital s}}{sup 2}) calculation of Kunszt and Nason.

37. ?-glucanase activity in the seastar Pisaster ochraceus

Abstract: Specimens of Pisaster ochraceus, an intertidal carnivorous seastar, were collected in northern Puget Sound at Post Point, near Bellingham, Washington, USA, in November 1993, and used in experimentation through September 1994. Ammonium sulfate fractions (60% precipitates) from excised pyloric caeca (digestive glands) possessed β-glucanase activity directed toward such β-linked substrates as carboxymethylcellulose (CMC), partially-digested cellulose (cellodextrins) and the synthetic substrate p-nitrophenyl-β-D-glucoside (PNDG). pH-activity and pH-stability maxima were at pH 6 and 5, respectively. No hydrolytic activity was detectable on native cellulose, native chitin or on cationic-modified celluloses such as DEAE-cellulose. Gel filtration (Sephadex G-100) of this 60% precipitate followed by DEAE-Sephadex column chromatography revealed heterogeneity of β-glucanase activity, with an indication of up to 11 distinct fractions with variable activity directed toward the substrates indicated above (CMC, cellodextrins and PNDG). These fractions displayed differing ratios of hydrolytic activity on these substrates. None of the isolated fractions displayed activity toward either native cellulose or native chitin. Gut extracts from the edible mussel (Mytilus edulis), a common prey species of P. ochraceus, were shown to possess partially digested cellulose (cellodextrins). These cellodextrins were further degraded by seastar β-glucanases in vitro. The digestion of the gut contents of ingested prey provides a possible adaptive explanation for the presence of β-glucanase activity in a carnivore.

Abstract: Using an impact parameter tag to select an enriched sample of {ital Z}{sup 0}{r_arrow}{ital bb}{ovr bar} events, and the net momentum-weighted track charge to identify the sign of the charge of the underlying {ital b} quark, we have measured the left-right forward-backward asymmetry for {ital b} quark production as a function of polar angle. Based on 1.8pb{sup {minus}1} of {ital Z}{sup 0} decay data produced with a mean electron beam polarization of {ital P}{sub {ital e}}=63%, this yields a direct measurement of the extent of parity violation in the {ital Zbb} coupling of {ital A}{sub {ital b}}=0.87{plus_minus}0.11(stat){plus_minus}0.09(syst).

Abstract: The parity-violating parameters ${A}_{b}$ and ${A}_{c}$ are directly measured by the SLD experiment at the SLAC Linear Collider in ${e}^{+}{e}^{\ensuremath{-}}$ collisions with polarized electrons at the ${Z}^{0}$ resonance. Leptons with distinctive total and transverse momenta are used to select and analyze ${Z}^{0}\ensuremath{\rightarrow}b\overline{b}$ and ${Z}^{0}\ensuremath{\rightarrow}c\overline{c}$ events. ${A}_{b}$ and ${A}_{c}$ are extracted by forming the left-right forward-backward asymmetry in electron beam polarization and quark polar angle. From our 1993 sample of 1.8 p${\mathrm{b}}^{--1}$ of ${Z}^{0}$ decay data with an average electron beam polarization of 63% we find ${A}_{b}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.91\ifmmode\pm\else\textpm\fi{}0.14$ (stat) $\ifmmode\pm\else\textpm\fi{}0.07$ (syst) and ${A}_{c}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.37\ifmmode\pm\else\textpm\fi{}0.23$ (stat) $\ifmmode\pm\else\textpm\fi{}0.21$ (syst).

Abstract: We have searched for signatures of polarization in hadronic jets from [ital Z][sup 0][r arrow][ital q[bar q]] decays using the jet handedness'' method. The polar angle asymmetry induced by the high SLAC Linear Collider electron-beam polarization was used to separate quark jets from antiquark jets, expected to be left and right polarized, respectively. We find no evidence for jet handedness in our global sample or in a sample of light quark jets, and we set upper limits at the 95% C.L. of 0.063 and 0.099, respectively, on the magnitude of the analyzing power of the method proposed by Efremov [ital et] [ital al].

Abstract: Summary Although variation in the KIT gene is a common cause of white spotting among domesticated animals, KIT has not been implicated in the diverse white spotting observed in the dog. Here, we show that a loss-of-function mutation in KIT recapitulates the coat color phenotypes observed in other species. A spontaneous white spotting observed in a pedigree of German Shepherd dogs was mapped by linkage analysis to a single locus on CFA13 containing KIT (pairwise LOD = 15). DNA sequence analysis identified a novel 1-bp insertion in the second exon that co-segregated with the phenotype. The expected frameshift and resulting premature stop codons predicted a severely truncated c-Kit receptor with presumably abolished activity. No dogs homozygous for the mutation were recovered from multiple intercrosses (P = 0.01), suggesting the mutation is recessively embryonic lethal. These observations are consistent with the effects of null alleles of KIT in other species.

Abstract: We determine the strong coupling ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$ from a comprehensive study of energy-energy correlations (EEC's) and their asymmetry (AEEC's) in hadronic decays of ${\mathit{Z}}^{0}$ bosons collected by the SLD experiment at SLAC. The data are compared with all four available predictions of QCD calculated up to O(${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}^{2}$) in perturbation theory, and also with a resummed calculation matched to all four of these calculations. We find large discrepancies between ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$ values extracted from the different O(${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}^{2}$) calculations. We also find a large renormalization scale ambiguity in ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$ determined from the EEC's using the O(${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}^{2}$) calculations; this ambiguity is reduced in the case of the AEEC's and is very small when the matched calculations are used. Averaging over all calculations, and over the EEC and AEEC results, we obtain ${\mathrm{\ensuremath{\alpha}}}_{\mathit{s}}$(${\mathit{M}}_{\mathit{Z}}^{2}$)=0.${124}_{\mathrm{\ensuremath{-}}0.004}^{+0.003}$ (expt.) \ifmmode\pm\else\textpm\fi{}0.009 (theory).

43. Activation of NF-kappa B and induction of vascular cell adhesion molecule-1 and intracellular adhesion molecule-1 expression in human glial cells by IL-1. Modulation by antioxidants

Author: P N Moynagh, D C Williams, and L A O'Neill
Subjects: Immunology, Immunology and Allergy
Abstract: The infiltration of leukocytes into the central nervous system is associated with many pathologic conditions of the brain. The mechanisms by which these immune cells can penetrate the blood-brain barrier and remain within the brain are not understood. However, elevated brain levels of the pro-inflammatory cytokine IL-1 appear to accompany pathogenesis. The present study provides the first evidence that IL-1 can induce the expression of adhesion molecules for leukocytes on glial cells and suggests a role for the transcription factor NF-kappa B in the induction process. Human rIL-1 alpha was found to induce the expression of the cell adhesion molecules, vascular cell adhesion molecule-1 (VCAM-1), and intercellular adhesion molecule-1 (ICAM-1) but not E-selectin in human 1321N1 astrocytoma. Both VCAM-1 and ICAM-1 were detectable from 3 h and remained sustained for up to 72 h. Induction was inhibited by the IL-1 receptor antagonist. IL-1 alpha was also shown to induce the expression of VCAM-1 and ICAM-1 in a receptor-dependent fashion in human A172 glioblastoma. Activation of the transcription factor NF-kappa B was also observed in 1321N1 astrocytoma in response to IL-1 alpha treatment and was similarly abolished by pretreatment of cells with antagonist. Activated NF-kappa B was apparent from 20 min and remained for up to 24 h. N-acetylcysteine (NAC) and pyrollidinedithiocarbamate (PDTC), which were shown to inhibit activation of NF-kappa B in Jurkat E6.1 lymphoblasts and EL4.NOB-1 thymoma, failed to block IL-1 activation of NF-kappa B in 1321N1 astrocytoma. However, both of these antioxidants demonstrated complex modulatory effects on the induction of cell adhesion molecule expression by IL-1. The induction of VCAM-1 but not of ICAM-1 proved susceptible to inhibition by both PDTC and NAC. The expression of adhesion molecules for leukocytes on glial cells in response to IL-1 may represent an important mechanism for retention of immune cells in the central nervous system that may be a prologue to inflammatory conditions in the brain.

Abstract: We present a precise measurement of the left-right cross section asymmetry ([ital A][sub [ital L][ital R]]) for [ital Z] boson production by [ital e][sup +][ital e][sup [minus]] collisions. The measurement was performed at a center-of-mass energy of 91.26 GeV with the SLD detector at the SLAC Linear Collider (SLC). The luminosity-weighted average polarization of the SLC electron beam was (63.0[plus minus]1.1)%. Using a sample of 49 392 [ital Z] decays, we measure [ital A][sub [ital L][ital R]] to be 0.1628[plus minus]0.0071(stat)[plus minus]0.0028(syst) which determines the effective weak mixing angle to be sin[sup 2][theta][sub [ital W]][sup eff]=0.2292[plus minus]0.0009(stat) [plus minus]0.0004(syst).

Abstract: Using an impact parameter tag to select an enriched sample of [ital Z][sup 0][r arrow][ital b[bar b]] events, we have measured the difference between the average charged multiplicity of [ital Z][sup 0][r arrow][ital b[bar b]] and [ital Z][sup 0][r arrow] hadrons to be [ital [bar n]][sub [ital b]][minus][ital [bar n]][sub had]=2.24[plus minus]0.30 ( stat )[plus minus]0.33 ( syst ) tracks per event. From this, we have derived [ital [bar n]][sub [ital b]][minus][ital [bar n]][sub [ital u][ital d][ital s]]=3.31[plus minus]0.41[plus minus]0.79. Comparing this measurement with those at lower center-of-mass energies, we find no evidence that [ital [bar n]][sub [ital b]][minus][ital [bar n]][sub [ital u][ital d][ital s]] depends on energy. This result is in agreement with a precise prediction of perturbative QCD, and supports the notion that QCD remains asymptotically free down to the scale [ital M][sub [ital b]][sup 2].

Abstract: Background The administration of certain sedatives has been shown to promote sleep in humans. Related agents induce sleep-like behavior when administered to horses. Interpretation of electroencephalograms (EEGs) obtained from sedated horses should take into account background activity, presence of sleep-related EEG events, and the animal's behavior. Hypothesis Sedatives induce states of vigilance that are indistinguishable on EEGs from those that occur naturally. Animals Six healthy horses. Methods Digital EEG with video was recorded after administration of 1 of 4 sedatives (acepromazine, butorphanol, xylazine, or detomidine). Serum drug concentrations were measured. Recordings were reviewed, states were identified, and representative EEG samples were analysed. These data were compared with data previously obtained during a study of natural sleep. Results Butorphanol was associated with brief episodes resembling slow wave sleep in 1 horse. Acepromazine led to SWS in 3 horses, including 1 that also exhibited rapid eye movement sleep. Periods of SWS were observed in all horses afer xylazine or detomidine administration. Normal sleep-related EEG events and heart block, occurred in association with SWS regardless of which sedative was used. Spectral data varied primarily by state, but some differences were observed between sedative and natural data. Conclusions and Clinical Importance Qualitatively, EEG findings appeared identical whether sedation-induced or naturally occurring. The startle response and heart block associated with some sedatives may be related to sleep. Alpha2 agonists can be used to obtain high quality EEGs in horses, but acepromazine does not promote a relaxed state in all animals.

Abstract: We report results from an updated study of the suppressed decays ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}D{K}^{\ensuremath{-}}$ and ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{*}{K}^{\ensuremath{-}}$ followed by $D\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, where ${D}^{(*)}$ indicates a ${D}^{(*)0}$ or a ${\overline{D}}^{(*)0}$ meson, and ${D}^{*}\ensuremath{\rightarrow}D{\ensuremath{\pi}}^{0}$ or ${D}^{*}\ensuremath{\rightarrow}D\ensuremath{\gamma}$. These decays are sensitive to the Cabibbo-Kobayashi-Maskawa unitarity triangle angle $\ensuremath{\gamma}$ due to interference between the $b\ensuremath{\rightarrow}c$ transition ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{(*)0}{K}^{\ensuremath{-}}$ followed by the doubly Cabibbo-suppressed decay ${D}^{0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, and the $b\ensuremath{\rightarrow}u$ transition ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\overline{D}}^{(*)0}{K}^{\ensuremath{-}}$ followed by the Cabibbo-favored decay ${\overline{D}}^{0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. We also report an analysis of the decay ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{(*)}{\ensuremath{\pi}}^{\ensuremath{-}}$ with the $D$ decaying into the doubly Cabibbo-suppressed mode $D\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. Our results are based on $467\ifmmode\times\else\texttimes\fi{}\phantom{\rule{0ex}{0ex}}{10}^{6}$ $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$ decays collected with the BABAR detector at SLAC. We measure the ratios ${\mathcal{R}}^{(*)}$ of the suppressed ($[{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{]}_{D}{K}^{\ensuremath{-}}/{\ensuremath{\pi}}^{\ensuremath{-}}$) to favored ($[{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{]}_{D}{K}^{\ensuremath{-}}/{\ensuremath{\pi}}^{\ensuremath{-}}$) branching fractions as well as the $CP$ asymmetries ${\mathcal{A}}^{(*)}$ of those modes. We see indications of signals for the ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}D{K}^{\ensuremath{-}}$ and ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}_{D{\ensuremath{\pi}}^{0}}^{*}{K}^{\ensuremath{-}}$ suppressed modes, with statistical significances of 2.1 and $2.2\ensuremath{\sigma}$, respectively, and we measure: ${\mathcal{R}}_{DK}=(1.1\ifmmode\pm\else\textpm\fi{}0.6\ifmmode\pm\else\textpm\fi{}0.2)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}2},\phantom{\rule{2em}{0ex}}{\mathcal{A}}_{DK}=\ensuremath{-}0.86\ifmmode\pm\else\textpm\fi{}{0.47}_{\ensuremath{-}0.16}^{+0.12}$, ${\mathcal{R}}_{(D{\ensuremath{\pi}}^{0})K}^{*}=(1.8\ifmmode\pm\else\textpm\fi{}0.9\ifmmode\pm\else\textpm\fi{}\phantom{\rule{0ex}{0ex}}0.4)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}2},\phantom{\rule{2em}{0ex}}{\mathcal{A}}_{(D{\ensuremath{\pi}}^{0})K}^{*}=+0.77\ifmmode\pm\else\textpm\fi{}0.35\ifmmode\pm\else\textpm\fi{}0.12,\phantom{\rule{2em}{0ex}}{\mathcal{R}}_{(D\ensuremath{\gamma})K}^{*}=(1.3\ifmmode\pm\else\textpm\fi{}1.4\ifmmode\pm\else\textpm\fi{}0.8)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}2},{\mathcal{A}}_{(D\ensuremath{\gamma})K}^{*}=+0.36\phantom{\rule{0ex}{0ex}}\ifmmode\pm\else\textpm\fi{}{0.94}_{\ensuremath{-}0.41}^{+0.25}$, where the first uncertainty is statistical and the second is systematic. We use a frequentist approach to obtain the magnitude of the ratio ${r}_{B}\ensuremath{\equiv}|A({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\overline{D}}^{0}{K}^{\ensuremath{-}})/A({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{0}{K}^{\ensuremath{-}})|=({9.5}_{\ensuremath{-}4.1}^{+5.1})%$, with ${r}_{B}l16.7%$ at 90% confidence level. In the case of ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{*}{K}^{\ensuremath{-}}$ we find ${r}_{B}^{*}\ensuremath{\equiv}|A({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\overline{D}}^{*0}{K}^{\ensuremath{-}})/A({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{*0}{K}^{\ensuremath{-}})|=({9.6}_{\ensuremath{-}5.1}^{+3.5})%$, with ${r}_{B}^{*}l15.0%$ at 90% confidence level.

Abstract: This paper addresses the need for detailed chemical information on the fine particulate matter (PM) generated by commercial aviation engines. The exhaust plumes of seven turbofan engine models were sampled as part of the three test campaigns of the Aircraft Particle Emissions eXperiment (APEX). In these experiments, continuous measurements of black carbon (BC) and particle surface-bound polycyclic aromatic compounds (PAHs) were conducted. In addition, time-integrated sampling was performed for bulk elemental composition, water-soluble ions, organic and elemental carbon (OC and EC), and trace semivolatile organic compounds (SVOCs). The continuous BC and PAH monitoring showed a characteristic U-shaped curve of the emission index (EI or mass of pollutant/mass of fuel burned) vs fuel flow for the turbofan engines tested. The time-integrated EIs for both elemental composition and water-soluble ions were heavily dominated by sulfur and SO(4)(2-), respectively, with a ∼2.4% median conversion of fuel S(IV) to particle S(VI). The corrected OC and EC emission indices obtained in this study ranged from 37 to 83 mg/kg and 21 to 275 mg/kg, respectively, with the EC/OC ratio ranging from ∼0.3 to 7 depending on engine type and test conditions. Finally, the particle SVOC EIs varied by as much as 2 orders of magnitude with distinct variations in chemical composition observed for different engine types and operating conditions.

Abstract: We report searches for B-meson decays to the charmless final states rho K* and f0(980) K* with a sample of 232 million BBbar pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We measure the following branching fractions in units of 10^{-6}: B (B+ --> rho0 K*+) = 3.6 +/- 1.7 +/- 0.8 ( rho+ K*0) = 9.6 +/- 1.7 +/- 1.5, B (B0 --> rho- K*+) = 5.4 +/- 3.6 +/- 1.6 ( rho0 K*0) = 5.6 +/- 0.9 +/- 1.3, B (B+ --> f0(980) K*+) = 5.2 +/- 1.2 +/- 0.5, and B (B0 --> f0(980) K*0) = 2.6 +/- 0.6 +/- 0.9 ( rho+ K*0) = 0.52 +/- 0.10 +/- 0.04, f_L (B0 --> rho0 K*0) = 0.57 +/- 0.09 +/- 0.08, A_CP (B+ --> rho+ K*0) = -0.01 +/- 0.16 +/- 0.02, A_CP (B0 --> rho0 K*0) = 0.09 +/- 0.19 +/- 0.02, A_CP (B+ --> f_0(980) K*+) = -0.34 +/- 0.21 +/- 0.03, and A_CP (B0 --> f_0(980) K*0) = -0.17 +/- 0.28 +/- 0.02.

Abstract: Botulism is a potentially fatal paralytic disorder for which definitive diagnosis is difficult.To determine if repetitive stimulation of the common peroneal nerve will aid in the diagnosis of botulism in foals.Four control and 3 affected foals.Validation of the test in healthy foals for its comparison in foals with suspected botulism. Controls were anesthetized and affected foals were sedated to avoid risks of anesthesia. The common peroneal nerve was chosen for its superficial location and easy access. Stimulating electrodes were placed along the common peroneal nerve. For recording, the active and reference electrodes were positioned over the midpoint and distal end of the extensor digitorum longus muscle, respectively. Repeated supramaximal stimulation of the nerve was performed utilizing a range of frequencies (1-50 Hz). Data analysis consisted of measuring the amplitude and area under the curve for each M wave and converting these values into percentages of decrement or increment based on the comparison of subsequent potentials to the initial one (baseline) within each set.A decremental response was seen at all frequencies in control foals. Decremental responses also were observed in affected foals at low frequencies. An incremental response was seen in all affected foals at 50 Hz.Decreased baseline M wave amplitudes with incremental responses at high rates are supportive of botulism. Repetitive nerve stimulation is a safe, simple, fast, and noninvasive technique that can aid in the diagnosis of suspected botulism in foals.
