1. The Dufour Effect in Film Cooling Experiments With Foreign Gases

Author: Carol E. Bryant, James L. Rutledge, Jacob P. Anthony Fischer, and Connor J. Wiese

Abstract: In typical film cooling experiments, the adiabatic wall temperature may be determined from surface temperature measurements on a low thermal conductivity model in a low-temperature wind tunnel. In such experiments, it is generally accepted that the adiabatic wall temperature must be bounded between the coolant temperature and the freestream recovery temperature as they represent the lowest and highest temperature introduced into the experiment. Many studies have utilized foreign gas coolants to alter the coolant properties such as density and specific heat to more appropriately simulate engine representative flows. In this paper, we show that the often ignored Dufour effect can alter the thermal physics in such an experiment from those relevant to the engine environment that we generally wish to simulate. The Dufour effect is an off-diagonal coupling of heat and mass transfer that can induce temperature gradients even in what would otherwise be isothermal experiments. These temperature gradients can result in significant errors in the calibration of various experimental techniques, as well as lead to results that at first glance may appear non-physical such as adiabatic effectiveness values not bounded by zero and one. This work explores Dufour effect induced temperature separation on two common cooling flow schemes, a leading edge with compound injection through a cylindrical cooling hole, and a flat plate with axial injection through a 7–7–7-shaped cooling hole. Air, argon, carbon dioxide, helium, and nitrogen coolant were utilized due to their usage in recent film cooling studies.

Abstract: This contribution presents a new application of the spouted bed technique. The developed production process involves coating fine copper particles with a polymer in a spouted bed plant and then hot pressing the produced granules to form a compact consisting of a copper–polymer composite with a high filling degree. The fabricated composites possess high relative permittivity, which is advantageous for the production of effective capacitors. With increasing filling degree of copper, the relative permittivity of the composites increased, with a maximum relative permittivity of 214 obtained for the composite containing 78.1 vol% copper. Such a high filling degree can be achieved with conductive particles without obtaining a conductive composite by using the spouted bed technology in the production process. The high relative permittivity results from the high filling degree of particles isolated by a polymer coating.

Abstract: The Lagrangian analysis of particulate matter, biota and drifters, which are dispersed by turbulent fluid currents, is a cornerstone of oceanographic studies, covering diverse study objectives. The results of Lagrangian simulations and observations is predominantly visualised by means of easy-access plotting interfaces and simple presentation techniques. We analysed over 50 publications from the years 2010–2020 with respect to their visual design to deduce common visualisation practices in the domain. Individual figures are analysed towards adherence to visualisation best-practices, algebraic visualisation guidelines and the IPCC visual style guide. In this article, we present the resulting best-practices and common pitfalls in the design of Lagrangian ocean visualisations. Based on this visual study, we highlight that raising awareness of established visual guidelines may have a higher impact on improving the visual quality of publications in oceanography than the vigorous development of more general-purpose visualisation tools.

Abstract: Introduction Patients with atrial fibrillation (AF) have an increased risk of thromboembolic events (TE), while patients with complicated liver cirrhosis have an increased risk of both TE and bleeding. Oral anticoagulation reduces the risk of TE in the general group of patients with AF but its use in patients with liver cirrhosis is obscured by their imbalance between endogenous procoagulants and anticoagulants, as well as the lack of data from randomized controlled trials. Purpose To examine the risks of TE and bleeding in patients with AF and complicated liver cirrhosis according to whether oral anticoagulation is initiated. Methods We conducted a nationwide registry-based study of anticoagulant-naive patients with complicated liver cirrhosis and first-time AF diagnosed between 2010–2017. Complicated liver cirrhosis was defined as liver cirrhosis plus one of the following: alcoholism, esophageal varices, ascites or hepatorenal syndrome. Patients were followed for a maximum of 5 years. TE was defined as a composite of ischemic stroke, transient ischemic attack or systemic thromboembolism; and the bleeding endpoint was defined as gastrointestinal, cerebral or urogenital bleeding requiring hospitalization, or any hospital contact with epistaxis. TE risk was estimated by use of the CHA2DS2-VASc score, while bleeding risk was estimated by use of the HAS-BLED score. Outcomes were stratified according to whether an oral anticoagulant (vitamin K antagonists [VKA] or direct oral anticoagulants [DOAC]) was initiated. Results We identified 770 patients with complicated liver cirrhosis and first-time AF. TE events occurred in 7.0% (n=25/359) of patients with a CHA2DS2-VASc score ≤2 versus 20.7% (n=85/411) of patients with a CHA2DS2-VASc score >2. Among 411 patients with a high CHA2DS2-VASc score, 111 (27.0%) were prescribed an oral anticoagulant (OAC+; VKA, n=53 [47.7%], DOAC, n=58 [52.3%]), while 300 (73.0%) were not treated with oral anticoagulation (OAC−). These two groups had comparable baseline data, including HAS-BLED (OAC+ 3.0 [2.5–4.0] versus OAC− 3.0 [2.0–4.0]) and CHA2DS2-VASc (OAC+ 4.0 [3.0–5.0] versus OAC− 4.0 [3.0–5.0]) scores. The 5-year TE risk among patients receiving anticoagulant therapy was 14.4% (n=16/111) versus 23.0% (n=69/300) in patients not treated with anticoagulant therapy (hazard ratio (HR) 0.55 [0.32–0.95]). The difference in bleeding risk was insignificant between the two groups (HR 0.67 [0.35–1.30]). Adjusting for CHA2DS2-VASc, HAS-BLED and prior bleeding requiring hospitalization did not significantly change the HR estimate, and no significant interactions were found. Conclusion TE risk was significantly lower in AF patients with complicated liver cirrhosis treated with oral anticoagulation, without a significantly increased bleeding risk. However, the majority of AF patients with complicated liver cirrhosis are not treated with anticoagulant therapy, indicating a potential for reducing the TE burden in this population.

Abstract: This paper provides an overview about the recently performed development of rigid polyurethane (PUR) foams on a cryogenic insulation for liquefied hydrogen (LH2) tanks application and gives information on the characterization test campaigns performed so far. Since this specific insulation is foreseen to be applied on inner surfaces of the propellant tanks it is called Inner Wetted Thermal Insulation (IWTI). The IWTI obtained by spraying method has been especially designed (with apparent core density 85 ± 2 kg/m3) for an optimum chemistry and cell structure morphology in order to achieve superior mechanical and thermal performance under these exceptional conditions. Studies of the foams` tension and compression properties at 295 and 77 K were carried out. The obtained safety coefficient of cryogenic insulation material reached 3.7.

Abstract: In the framework of the present activity, work is carried out on the development of rigid polyurethane (PUR) foam material for external cryogenic insulation of a liquefied hydrogen (LH2) tank for the next generation launcher with a cryogenic upper stage. The main advantage of PUR foams in comparison with other thermal insulation materials is possibility to cover this material on the complicated shape metal surfaces by spraying method, which leads to significant cost savings. The spraying of PUR foams on metal constructions is chemical-technological process. As a result of work performed within the confidential European Space Agency contract, PUR foam material has been developed for the use as external insulation material for fuel tank structures. Raw ingredients from suppliers within EU have been used exclusively. The material has been tested for its performance in normal (room) and relevant (cryogenic conditions) environment and found to be mechanically durable and thermally excellent and therefore appropriate for use in space application. Accelerated ageing test indicate the material to be long-lasting. Safety coefficient, which characterizes the capability of insulation to withstand cryo-shocks, for optimal compositions reaches 4.7.

Abstract: The effectiveness of memantine on the symptoms of Parkinson's disease was investigated in 67 patients (39 males, 28 females) mostly between 55 and 75 years. The study was multi-center placebo-controlled with four treatment groups, i. e. patients with and without pre- and after-treatment with other anti-Parkinson medication receiving either placebo or memantine as sole or additional medication. The analysis of 61 evaluable cases showed a positive statistically significant influence on the single symptom tremor as well as on the neurological overall symptomatology (Webster-scale total score). Despite the inadequately ascertained mode of action memantine promises success particularly in milder and initial forms of the Parkinson syndrome either used as monotherapy or as an adjuvant.

Abstract: Toxoplasmosis encephalitis developed in three male homosexuals with AIDS. Clinical symptoms of encephalitis began with a nonspecific organic mental syndrome. In two cases there developed late focal symptoms. There were light to moderately severe generalized EEG changes with additional focal signs. CSF findings and toxoplasmosis titres were not diagnostically altered. Computed tomography demonstrated multiple areas of decreased density in cortex and cerebellum. Administration of pyrimethamine and sulfamethoxydiazine to the three patients brought about clinical improvement within a few days and regression of abnormal CT changes within a few weeks of onset of treatment. One patient died after an encephalitis recurrence: autopsy demonstrated toxoplasma pseudocysts in immediate proximity to small necrotic foci in the brain. The possibility of toxoplasma encephalitis should be considered in AIDS patients who develop an organic mental syndrome. Often the diagnosis can only be made after response to a trial of toxoplasmosis treatment.

Abstract: Changes in blood flow velocity of the middle cerebral artery (MCA) were measured by transcranial Doppler Sonography in 10 healthy subjects during a 10-minute period of moderate bicycle exercise. During physical exercise, a marked increase in heart rate (+63%) und ventilation rate (+48%) and a moderate increase in mean arterial blood pressure (+16%) were found. The end tidal carbon dioxide partial pressure rose in all cases by a mean value of 6.7 mmHg. The MCA flow velocity increased from 62 cm/s to 75 cm/s by 13 cm/s or 21% (mean values). When corrected to a standard pCO2 of 40 mmHg no significant changes in flow velocities (-1 cm/s) were found. Our Doppler sonographic findings indicate that during moderate physical exercises the MCA flow velocity - and the cerebral circulation - are regulated by the carbon dioxide partial pressure and not by cardiac output.

Abstract: The effect of postural blood pressure changes on the blood flow velocity in the middle cerebral artery (MCA) was studied with transcranial Doppler sonography in 45 patients with intact circulatory reflexes and in 30 cases with postural hypotension. In an upright position on the tilt-table the patients with intact cardiovascular reflexes showed a small decrease of the MCA flow velocity of 3% (1.5 cm/sec), whereas there was found a marked reduction in the cases with postural hypotension. In the group with an asympathicotonic response (n = 14) there was an average decrease of 24% (13 cm/sec) and a 28% drop of mean arterial blood pressure. The lower percentage of reduction of the cerebral blood flow velocity can be explained as an effect of cerebral autoregulation. In the group with a sympathicotonic response (n = 16) a surplus reduction of the flow velocity of 17% (7 cm/sec) was seen, compared to a 7% decrease in blood pressure. This corresponds with the results of experimental animal studies which showed an impaired cerebral autoregulation during increased sympathico-adrenal discharge.

Abstract: Background: Aim of this study was the development of a screening questionnaire for allergic respiratory diseases. The questionnaire should be as short as possible and easy to administer. Methods: The test version consisted of 33 items asking for the occcurrence of typical symptoms and whether these symptoms were associated with specific circumstances (e.g. season, contact to animals). Additionally, the severity of symptoms was rated on a 10-point scale. The questionnaire was tested on a sample of patients from the practices of 185 dermatologists, ENT physicians, pulmonologists and pediatricians who were all specialized in allergology. Each study physician should include all subsequent patients who visited the practice for the first time during a specified period (April - July 2003). Of 13,604 documented cases 8,822 patients could be included in the analysis. Excluded patients had either incomplete data or diagnostic assessment was not finished. Allergic airway disease was confirmed by positive skin or laboratory tests in 1,562 of these patients (prevalence 17.7%). Logistic regression analyses were performed to identify the questionnaire items most predictive of a diagnosis of allergic airway disease. For these items, a simplified scoring procedure was defined leading to the calculation of the additive ASF Score (range 0 - 24) for each patient. To determine cut-points of the ASF Score for the diagnosis of allergic airway disease we calculated the sensitivities, specificities and predictive values for all possible values of the score and for 3 prevalences. Results: The multivariate regression model identified 12 items (Nagelkerke R 2 = 0.532). Depending on the study purposes, 2 cut-points of the ASF Score are recommended that yield positive predictive values (at prevalence 17,7%) of 50% or of 67%, respectively. Conclusion: The ASF Questionnaire is an effective screening test to identify patients with possible allergic airway disease that is very short and easy to administer.

Abstract: Obesity is associated with metabolic derangement and non-alcoholic fatty liver disease (NAFLD). Macrophages are involved in liver inflammation and fibrosis, and soluble (s)CD163 is a macrophage activation marker.To associate sCD163 with parameters of paediatric obesity and NAFLD, as well as changes in these parameters during lifestyle intervention.We studied 117 obese children during a 10-week lifestyle intervention; 71 completed the 12-month follow-up. We recorded clinical and biochemical data, and performed liver ultrasonography.Baseline sCD163 was higher in children with elevated alanine transaminase (ALT) (2.3 ± 0.7 vs. 2.0 ± 0.6 mg L(-1), P = 0.03), steatosis (2.3 ± 0.7 vs. 2.0 ± 0.6 mg L(-1), P = 0.01) and high paediatric NAFLD fibrosis index (2.3 ± 0.7 vs. 1.9 ± 0.6 mg L(-1) , P = 0.03). Baseline sCD163 was independently associated with ALT, cholesterol and high-sensitivity C-reactive protein (hs-CRP). The change in sCD163 during lifestyle intervention was associated with changes in ALT, homeostatic model assessment of insulin resistance (HOMA-IR), hs-CRP and cholesterol, and inversely associated with the change in high-density lipoprotein cholesterol.sCD163 was associated with markers of liver injury and metabolic parameters in obese children, and changes in these parameters during lifestyle intervention. This may suggest that activated macrophages play a role in NAFLD and sCD163 may serve as a marker of liver disease severity and treatment effect.

Abstract: In the present study we have analysed the effect of HLA-DRB1 and -DQB1 alleles on disease progression and genetic predisposition among 201 RA patients. We clearly confirm the association of RA with HLA class II alleles sharing the (Q)R/KRAA amino acid (AA) cassette in the third hypervariable region (HVR3) of the DRSS-chain. The HVR3 (Q)R/KRAA motif was significantly overrepresented among RA patients (79% vs. 40%, P < 0.001), with one third of the patients homozygous (28% vs. 6.7%, P < 10 -9 ) and the number of rheumatoid factor positive (RF +) patients was significantly increased among HVR3 (Q)R/KRAA homozygous in comparison to HVR3 (Q)R/KRAA negative individuals. Erosive disease defined by the Larsen Score and personal disability determined using the Health Assessment Questionnaire (HAQ) was significantly increased among patients positive for the HVR3 motif with the worst outcome among HVR3 (Q)R/KRAA homozygous patients. In contrast, there was no association of the shared HVR3 AA cassette and disease severity in the majority of patients presenting systemic (extraarticular) disease. Homozygosity for the shared HVR3 motif was only marginally increased among patients presenting 'severe' extraarticular disease in comparison to patients with articular disease (33% vs. 43%, P = ns). Similarly, patients with nodular disease were not more often homozygous for the HVR3 (Q)R/KRAA motif.

Abstract: A search for events with one jet and at most one isolated lepton used data taken at LEP-2 by the DELPHI detector.These data were accumulated at a center-of-mass energy of 183 GeV and correspond to an integrated luminosity of 47.7 1/pb. Production of single scalar and vector leptoquarks was searched for. Limits at 95% confidence level were derived on the masses (ranging from $134 GeV/c^2$ to $171 GeV/c^2$ for electromagnetic type couplings) and couplings of the leptoquark states.A search for top-charm flavour changing neutral currents($e^+ e^- \to \bar t c$ or charge conjugate) used the semileptonic decay channel. A limit on the flavour changing cross-section via neutral currents was set at 0.55pb (95% confidence level).

Abstract: An update of the searches for charginos and neutralinos is presented, based on a data sample corresponding to the 53.9 pb−1 recorded by the DELPHI detector in 1997, at a centre-of-mass energy of 183 GeV. No evidence for a signal was found. The lower mass limits are 4–5 GeV/c2 higher than those obtained at a centre-of-mass energy of 172 GeV. The (μ,M2) domain excluded by combining the neutralino and chargino searches implies a limit on the mass of the lightest neutralino which, for a heavy sneutrino, is constrained to be above 29.1 GeV/c2 for tanβ≥ 1.

Abstract: The total and the differential cross sections for the reaction e+e− → γγ(γ) have been measured with the DELPHI detector at LEP using an integrated luminosity of 36.9 pb−1. The results agree with the QED predictions and consequently there is no evidence for non-standard channels with the same experimental signature. The lower limits obtained on the QED cutoff parameters are Λ+ > 143 GeV and Λ− > 120 GeV, and the lower bound on the mass of an excited electron with an effective coupling constant λγ = 1 is 132 GeV/c2. Upper limits on the branching ratios for the decays Z0 → γγ, Z0 → π0γ, Z0 → ηγ and Z0 → γγγ have been determined to be 5.5 × 10−5, 5.5 × 10−5, 8.0 × 10−5, and 1.7 × 10−5 respectively. All the limits are at the 95% confidence level.

Abstract: Trisdipicolinate coordination complexes of europium(III), Eu(dpa)33-, have chiral, three-bladed propeller-like structures with either left-handed or right-handed structural helicity about a 3-fold symmetry axis. The left- and right-handed forms of these structures, labeled here as Λ and Δ, respectively, are structural enantiomers, and they exhibit characteristic circular dichroic absorption and emission properties in their optical excitation and luminescence spectra. In solution media that contain no other chiral species, the Eu(dpa)33- complexes exist as a racemic mixture of interconverting Λ and Δ enantiomeric structures (optical isomers). This racemic mixture of Λ- and Δ-Eu(dpa)33- complexes exhibits no chiroptical properties; but if it is excited with a pulse of circularly polarized light, partially resolved ground- and excited-state populations of Λ and Δ enantiomers are created, and these populations exhibit chiroptical properties reflective of their enantiomeric compositions (defined in terms of en...

24. Asthma severity and susceptibility to air pollution

Abstract: Exacerbations of asthma have been associated with exposure to ozone or particles with a 50% cut-off aerodynamic diameter of 10 microm (PM10). We postulated in this study that the association of summertime air pollution (i.e. ozone and PM10) with acute respiratory symptoms, medication use and peak expiratory flow differs among patients grouped according to asthma severity. During the summer of 1995, effects of ambient air pollution on these parameters were studied in a panel of 60 nonsmoking patients with intermittent to severe persistent asthma. These patients were recruited from our Pulmonary Out-patient Clinic. Subgroup analysis was performed on the degree of hyperresponsiveness and lung steroid use before the start of the study, as indictors for the severity of asthma. Associations of the parameters studied with ozone, PM10, nitrogen dioxide (NO2), sulphur dioxide (SO2) and black smoke were evaluated using time series analysis. Several episodes with increased summertime air pollution occurred during the 96 day study period. Eight hour average ozone concentrations exceeded the World Health Organization (WHO) Air Quality Guidelines (120 microg x m(-3)) on 16 occasions. Daily mean levels of PM10 were moderately elevated (range 16-98 microg x m(-3)). Levels of the other measured pollutants were low. There was a consistent, positive association of the prevalence of shortness of breath (maximal relative risk (RRmax) 1.18) with ozone, PM10, black smoke and NO2. In addition, bronchodilator use was associated with both ozone and PM10 levels (RRmax 1.16). Stratification by airway hyperresponsiveness and steroid use did not affect the magnitude of the observed associations. No associations with peak expiratory flow measurements were found. We conclude that the severity of asthma is not an indicator for the sensitivity to air pollution.

Abstract: A search for stable or long-lived heavy charged particles in e+e− interactions at energies of 130–136, 161 and 172 GeV has been performed using the data taken by the DELPHI experiment at LEP. The search is based on particle identification provided by the Time Projection Chamber and the Ring Imaging Cherenkov detector. Upper limits at 95% confidence level are derived on the cross-section for heavy long-lived pair-produced charge ±e and View the MathML source particles in the range of 0.4–2.3 pb for masses from 45 to 84 GeV/c2. Within supersymmetric extensions of the Standard Model, long-lived charginos with masses from 45 to 84 (80) GeV/c2 for high (low) sneutrino masses can be excluded at 95% confidence level. Left-handed (right-handed) long-lived or stable smuons and staus with masses between 45 and 68 (65) GeV/c2 can be excluded at 95% confidence level.

Abstract: We have searched for excited states of charged and neutral leptons, e∗, μ ∗ , τ ∗ and ν ∗ , in e+e− collisions at s =130 using the OPAL detector at LEP. No evidence for their existence was found. With the most common coupling assumptions, the final states from excited lepton pair production include l+l−γγ and l+l−WW (with the subsequent decay of the virtual W bosons). From the analysis of these final states, 95% confidence level lower mass limits of 66.5 GeV for e∗, 66.8 GeV for μ ∗ , 65.3 GeV for τ ∗ , 66.2 GeV for ν e ∗ , 66.5 GeV for ν μ ∗ and 64.7 GeV for ν τ ∗ are inferred. From the analysis of γγ final states with missing energy and using alternative coupling assignments which permit photonic ν ∗ decays, a 95% confidence level lower mass limit of 65.0 GeV for each ν ∗ flavour is inferred. From the analysis of the l+l−γ, acoplanar lepton pair, and single γ final states expected from excited lepton single production, upper limits on f Λ (ratio of the coupling to the compositeness scale) are determined for excited lepton masses up to the kinematic limit.

Abstract: Using data accumulated by DELPHI during the November 1995 LEP run at 130–136 GeV, searchs have been made for events with jets or leptons in conjunction with missing momentum. The results are interpreted in terms of limits on the production of neutralinos, scalar leptons, and scalar quarks.

Abstract: This is a report on a case of herpes simplex encephalitis (HSE) taking an unusual course after initially successful acyclovir therapy. The etiology of HSE was proven serologically, by repeated detection of herpes simplex virus (HSV)-specific DNA sequences in cerebrospinal fluid (CSF) with polymerase chain reaction (PCR) and was supported by cerebral imaging. After both the neurological symptoms and laboratory findings had improved initially under acyclovir therapy, the patient's clinical condition deteriorated accompanied by a renewed increase in CSF pleocytosis and protein content. Nuclear magnetic resonance (NMR) imaging confirmed the finding of bilateral, mainly temporal lesions compatible with a diagnosis of relapsing HSE. The patient responded well to a second cycle of antiviral therapy but required a third treatment cycle due to renewed deterioration later on. HSV-specific DNA sequences could not be demonstrated in several consecutive CSF samples taken after the first week of illness but increased inflammatory changes typical of HSE were seen on NMR during phases of deterioration. IgM-class antibodies against HSV were detected in CSF 4 weeks after onset of symptoms and stayed positive for at least 7 weeks. Reasons for the repeated deterioration and possible explanations for the absence of HSV DNA in spite of what could be seen as relapses are discussed.

Abstract: This letter reports the results of the measurement of single photon production in the reaction e+e− → γ+ invisible particles at centre-of-mass energies View the MathML source and 136 GeV and an integrated luminosity of 5.83 pb−1, collected with the DELPHI detector at LEP. The signal is compatible with the prediction of the Standard Model for the process View the MathML source, and the number of neutrino families has been determined to be Nν = 3.1 ± 0.6. Limits have been derived on anomalous neutral gauge boson couplings and on compositeness in the framework of a specific model.

Abstract: During the last 1995 data acquisition period at LEP, the DELPHI experiment collected an integrated luminosity of 5.9 pb−1 at centre-of-mass energies of 130 GeV and 136 GeV. Radiative leptonic events (e, μ, τ) with high energy photons were studied and compared to Standard Model predictions. The data were used to search for charged excited leptons decaying through an electromagnetic transition. No significant signal was found. From the search for pair produced excited leptons, the limits View the MathML source, View the MathML source and View the MathML source at 95% confidence level were established. For single excited lepton production, upper limits on the ratio View the MathML source of the coupling of the excited charged lepton to its mass were derived.

Abstract: From the data collected by DELPHI at LEP in autumn 1995, the multiplicity of charged particles at a hadronic energy of 130 GeV has been measured to be 〈nch〉 = 23.84 ± 0.51 (stat) ± 0.52 (syst). When compared to lower energy data, the value measured is consistent with the evolution predicted by QCD with corrections at next-to-leading order, for a value αs(130 GeV) = 0.105 ± 0.003 (stat) ± 0.008 (syst).

Abstract: The performance of OLX-209 indicates it should enter phase I clinical testing. OLX-209 is a recombinant toxin targeting the erbB-2 oncoprotein. The design of OLX-209 takes advantage of improvements in immunotoxin technology to produce a molecule that is smaller and more potent than a conventional chemically linked antibody-toxin conjugate. The targeting portion of OLX-209 is a single chain antibody structure derived from the anti-erbB-2 hybridoma, e23. This antibody has unusual specificity in that it does not bind to most normal tissue including peripheral nerve or kidney tissue. Preclinical testing shows in vitro activity against breast cancer cell lines in the pM range. Efficacy testing in five models of human cancer indicates that a dose of 43 micrograms/kg causes reproducible tumor regressions. Efficacy can be achieved on a variety of schedules of administration. The effective dose results in no measurable change in serum liver enzymes when delivered to mice or primates. The LD10 is over twice the effective dose in mice. The pharmacokinetics indicate a t 1/2 of 50 minutes for both mice and cynomolgus monkeys. Serum concentrations of more than ten times those observed at the effective dose can be achieved in monkeys with no evidence of toxicity. Antigenicity of OLX-209 is surprisingly low. These results form the basis for the clinical testing phase for OLX-209.

Abstract: The abundance of CA/GT repeats in the DNA of the dog (Canis familiaris) has established the importance of polymorphic microsatellites in the development of a low density map of the canine genome. The assignment of linkage groups of markers to chromosomes by physical mapping requires reliable cytogenetic techniques for routine production of metaphase cells. The dog has 78 chromosomes, many of which are smaller and more contracted than those of other mammals. Although the molecular study of inherited disease in dogs has important implications for both improved welfare in dogs and the provision of animal models for human diseases, the small size and large number of chromosomes in the canine genome has discouraged the inclusion of cytogenetic analysis in the planning of relevant research protocols. In this report, Fluorescence In Situ Hybridization (FISH) techniques have been optimized for the physical mapping of probes in C. familiaris. A method to obtain a good yield of early and midmetaphases from short-term peripheral blood cultures and the optimal conditions for hybridization and detection of probes is described. Thirteen microsatellite-containing cosmid probes from a canine genomic library in pWE15, a highly repetitive probe (human ribosomal DNA pHr14E3), and a human X Chromosome (Chr) paint have been mapped. Six microsatellites, two ribosomal sites, and the human paint have been assigned to specific chromosomes.

Abstract: Optical absorption measurements are used to locate and assign 79 crystal-field (Stark) levels split out of the 4f 3 electronic configuration of Nd 3+ in single crystals of neodymium nonahydrate tris(trifluoromethanesulfonate), [Nd(H 2 O) 9 ](CF 3 SO 3 ) 3 , denoted hereafter as NdTRF. Line strengths are determined for 56 transitions between Stark levels. Single crystals of NdTRF have hexagonal, P6 3 /m(C 6h 2 ) space-group symmetry, and each Nd 3+ ion is coordinated to nine water molecules in a slightly distorted tri-capped trigonal prism structure of C 3h symmetry. The energy-level structure of 4f 3 (Nd 3+ ) in NdTRF is analyzed in terms of a model Hamiltonian that includes consideration of both one-electron crystal-field and two-electron correlation-crystal-field interactions, the latter interactions making important contributions to the energy-level structures of several 4f 3 [ SL ] J multiplet manifolds. Line strength data obtaibned for NdTRF is analyzed in terms of a general 4f → 4f transition intensity model in which the details of the 4f-electron/crystal-field/electric-dipolar radiation-field interactions are represented in parametric form. The derived parameters provide information about structural properties and interaction mechanisms that contribute to 4f → 4f transition intensities. The general crystal-field and intensity parameters are further analyzed in terms of a set of ‘intrinsic’ parameters that are related to contributions from individual Nd 3+ OH 2 pairwise interactions.

39. Chiral discrimination in electronic energy-transfer processes in solution. Effects of temperature and solution properties on chirality-dependent rate parameters

Abstract: Time-resolved chiroptical luminescence (TR-CL) measurements are used to study the kinetics of chilality-dependent excited-state quenching processes in solution. Solution samples contain a racemic mixture of chiral luminophore molecules (L) and a small, optically-resolved concentration of chiral quencher molecules (Q) in an achiral solvent (H 2 O, D 2 O, or an H 2 O-ethylene glycol mixture). The luminophores are excited with a pulse of unpolarized light to create an initially racemic excited-state population of ΔL ∗ and ΛL ∗ enantiomers, and TR-CL measurements are then used to monitor the differential decay kinetics of the ΔL ∗ and ΛL ∗ subpopulations. Observed differences between the ΔL ∗ and ΛL ∗ decay kinetics differential rate processes and efficiencies for ΔL ∗ -Q versus ΛL ∗ -Q quenching actions, and they are diagnostic of chiral discriminatory interactions between the luminophore and quencher molecules. In each of the systems examined here, quenching occurs via electronic energy-transfer processes in transient (ΔL ∗ -Q) and (ΛL ∗ -Q) encounter complexes, and the chiral discriminatory rate parameters reflect the relative stabilities and lifetimes of these complexes as well as their structures and internal (electronic and nuclear) dynamics. Both quenching rates and enantioselectivity are observed to increase with increasing temperature over the temperature ranges represented in this study (253–353 K for H 2 O-ethylene glycol solutions and 273–353 K for H 2 O and D 2 O solutions), and differences between the free-energies of activation for ΔL ∗ -Q versus ΛL ∗ -Q quenching processes increase from ≈ 2.5 to 4.8 kJ/mol over the 273–353 K temperature range. Both the luminophore and quencher molecules examined in this study have three-bladed propeller-like structures with very similar shapes and sizes, and differential steric constraints in (ΔL ∗ -Q) versus (ΛL ∗ -Q) contact pairs are small. However, at room temperature and above, the relative efficiencies of ΔL ∗ -Q versus ΛL ∗ -Q quenching processes differ by factors > 3.2, indicating an extraordinary degree of chiral discrimination in the underlying interaction processes.

Abstract: A measurement of B meson lifetimes is presented using data collected from 1991 to 1993 by the DELPHI detector at the LEP collider. Samples of events with a D meson and a lepton in the same jet are selected where$\bar D^{^0 } \ell ^ + $ and D*l+ events originate mainly from the semileptonic decays of B+ and B0 mesons, respectively. From the reconstructed B decay length and the estimated B momentum, taking into account the dilution due to B decays into$\bar D^{^{**} } \ell ^ + v$, the following B meson lifetimes and lifetime ratio are measured: $$\begin{gathered} \tau (B^ + ) = 1.61_{ - 0.16}^{ + 0.16} (stat.) \pm 0.12(syst.) ps \hfill \\ \tau (B^0 ) = 1.61_{ - 0.13}^{ + 0.14} (stat.) \pm 0.08(syst.) ps \hfill \\ \tau (B^ + )/\tau (B^0 ) = 1.00_{ - 0.15}^{ + 0.17} (stat.) \pm 0.10(syst.) \hfill \\ \end{gathered} $$ and an average lifetime of B+ and B0 mesons is obtained: $$\tau (B) = 1.61_{ - 0.07}^{ + 0.08} (stat.) \pm 0.05(syst.) ps$$

41. Observation of the Potential-Dependent Second Harmonic Response from the Si(111)/Electrolyte and Si(111)/SiO2/Electrolyte Interfacial Regions

Abstract: The optical second harmonic (SH) response from the n-Si(111) surface immersed in aqueous electrolyte solutions has been examined and is observed to be potential dependent. This potential dependence is observed for both the monohydrogen-terminated surface immersed in NH[sub 4]F as well as for surfaces which are photoanodically oxidized in H[sub 2]SO[sub 4]. The potential dependence from the latter is screened in part by the presence of the insulating overlayer. Furthermore, a minimum is observed in the potential-dependent response which is shifted well anodic of the flatband potential. The SH observations are attributed to field effects within the space charge region of the semiconductor which are manifested in the higher order bulk SH response. Photocurrent transient analysis is utilized as a means of determining the flatband potential of these surfaces immersed in electrolyte solution. Experiments performed in UHV are discussed and compared to that observed in solution. 71 refs., 9 figs., 1 tab.

Abstract: The potential dependence in the surface second harmonic response from hydrogen terminated n‐Si(111) and oxidized n‐Si(111) surfaces has been examined in aqueous NH4F and H2SO4 solutions. The relative phase of the nonlinear response as measured by rotational anisotropy experiments is found to be highly sensitive to the presence of the oxide and the field applied across the Si(111)/oxide/electrolyte interface. These observations are attributed to field effects within the space–charge region of the semiconductor which vary with the presence and thickness of the insulating oxide layer on the Si(111) surface.

44. Induction, characterization, and functional coupling of the high affinity chemokine receptor for RANTES and macrophage inflammatory protein-1 alpha upon differentiation of an eosinophilic HL-60 cell line

Author: G Van Riper, D W Nicholson, M P Scheid, P A Fischer, M S Springer, and H Rosen
Subjects: Immunology, Immunology and Allergy
Abstract: Eosinophilic differentiation of a pro-eosinophilic HL-60 cell line resulted in the induction of a high affinity RANTES/macrophage inflammatory protein-1 alpha receptor. The induced receptor is biochemically indistinguishable in RANTES equilibrium-binding studies from the monocytic receptor expressed on THP-1 cell membranes. Continued expression of the receptor requires the continuous presence of the inducing stimulus, and receptor site number declines without a loss of binding affinity with a t1/2 of 11.5 h on withdrawal of the inducing stimulus. The induced receptor is capable of three physiologic measures of receptor coupling, namely, ligand-induced Ca2+ fluxes, priming of the respiratory burst, and chemotaxis. Dose-dependent Ca2+ fluxes were elicited upon increasing concentrations of RANTES and MIP-1 alpha whereas no response was measured upon addition of MIP-1 beta or MCP-1. In addition, desensitization studies demonstrated that previous exposure to either RANTES or MIP-1 alpha almost completely inhibits a Ca2+ flux upon subsequent exposure to either ligand. Priming of the respiratory burst to PMA in differentiated cells by human rRANTES was more effective than priming by IL-5 or granulocyte-macrophage-CSF, whereas undifferentiated cells failed to secrete superoxide anion. In addition, differentiated cells underwent chemotaxis in response to RANTES. This provides the first evidence for the induction of a C-C chemokine receptor upon eosinophilic differentiation of a leukocyte cell line, and is in keeping with the demonstrated ability of human RANTES to induce the rapid formation of eosinophilic inflammatory sites.

46. Relationship between multiple biologic effects of rapamycin and the inhibition of pp70S6 protein kinase activity. Analysis in mutant clones of a T cell lymphoma

Subjects: Immunology, Immunology and Allergy
Abstract: Rapamycin (RAP) inhibits several biologic responses in the YAC-1 T cell lymphoma, including the serum-driven proliferation and cyclin A mRNA expression, the induction of Ly-6E Ag expression by IFN, and the induction of IFN-gamma production by IL-1. RAP also suppresses the enzymatic activity of the 70 kDa S6 protein kinase (pp70s6k). To define the mechanistic relationship between these multiple effects of RAP, we have generated stable somatic mutants with altered sensitivities to this drug. A first series of mutants, represented by the R19, 4R16, and 10R13 clones, showed markedly reduced sensitivity to the inhibitory effect of RAP on all biologic responses tested and on pp70s6k activity. Two other mutant types, R103 and R125, were both highly sensitive to RAP-mediated suppression of proliferation, of IL-1-induced IFN-gamma production, and of pp70s6k activity but differed in their Ly-6E response. This response was not affected by RAP in the R125 clone and was enhanced in the R103 clone. Therefore, the inhibitory effects of RAP on proliferation and IL-1-mediated IFN-gamma induction both appear associated with the inhibition of pp70s6k activity, whereas the modulation of Ly-6E induction is independent from the latter. Moreover, the cellular binding of [3H]dihydro-FK-506 was found to be blocked by RAP in all mutant types to the same extent as in wild-type YAC-1 cells, suggesting that the altered sensitivity to the effects of RAP in these mutants is not due to an inability of the drug to enter the cells or to interact with FKBP. Further biochemical characterization of the mutant cells described here is expected to help clarify the mechanisms of RAP action.

47. Surface second harmonic studies of Si(111)/electrolyte and Si(111)/SiO2/electrolyte interfaces

Abstract: The optical second harmonic (SH) response from Si(111) electrode surfaces has been studied and has been found to be highly potential dependent. For both H-terminated Si(111) surfaces in NH 4 F, and oxide-covered surfaces biased in H 2 SO 4 , the phase and the amplitude display a potential dependence which are attributed to field effects within the semiconductor space—charge region and at the surface of the Si(111) electrode. These studies are the first to demonstrate that for Si(111)/oxide samples, the potential dependence in the SH phase can be correlated with oxide thickness, as demonstrated by examining samples of 0–40 A thickness.

49. Tropical Pediatrics

Author: P R, Fischer
Subjects: Diarrhea, Tropical Climate, Child, Preschool, Pediatrics, Perinatology and Child Health, Humans, Child, Child Nutrition Disorders, Pediatrics, Poverty, Malaria
Abstract: Tropical pediatrics often is more a study of the consequences of poverty than of exotic infections. Pediatricians involved with the care of children in or from the tropics must deal with poverty, place an appropriate emphasis on preventive medicine, and seek to bridge their own cultural and linguistic barriers. Malaria, diarrheal disease, and malnutrition account for a large part of pediatric morbidity and mortality in tropical countries. P falciparum can cause severe malarial disease. Treatment must be initiated promptly; resistance to antimalarial drugs is possible. Hygienic and nutritional prevention of diarrhea must be coupled with widespread use of oral rehydration therapy for acute cases of diarrhea. Identification and early treatment of mildly malnourished children can prevent some of the mortality of overt marasmus and kwashiorkor.

Abstract: Despite widespread use in pharmacotherapeutical trials, in the majority of rating scales used in Parkinson's disease (PD) validity, reliability and appropriate use have never been confirmed by statistical data. For this reason 350 unselected PD-pats. were investigated by an extensive standardized test-battery including registration of basis data, Columbia University Rating Scale (CURS), scale for assessment of functional disability (ADL), SCAG-scale, HoehnJahr-scale (HY), mod. Webster step second-test (WSST), Purdue-pegboard, questionnaire for subjective complaints (SC), WDG, LPS1/2, 3/4, 6, 7, 10, clinical assessment of dementia, v. Zerssen-scale and orthostatic hypotension (60 degrees tilt up). For CURS, SCAG and ADL instrumental reliability was calculated by Cronbach's alpha. For CURS, SCAG, ADL and the total data of complete test battery (CTB) principal component analysis (PCA) was performed for data reduction. CURS, SCAG and ADL showed high internal consistency (alpha approximatelyor = 0.9). For CURS 5 factors accounting for 66% total variance could be extracted by PCA. They represent gait, rigidity, tremor, right/left dexterity (eigenvalues1). For SCAG 3 factors (61% of total variance) representing dementia, depression and change of personality were extracted. For ADL 3 factors (67% of total variance) could be extracted, representing overall functional disability, handwriting and disability by pain. PCA of the CTB identified 8 interpretable factors (66% of total variance) characterizing at least partially the clinical profile of PD: 1. motor disability (assessment by rating-scales) 2. dementia, 3. motor-disability (assessment by apparative measurements), 4. depression, 5. orthostatic hypotension, 6. WDG, 7. tremor and 8. pain. Our data confirm the suitability of the investigated scales and give a rational base for their appropriate use in a sense of data reduction and economical evaluation.
