Abstract

Scrapie infectivity enters the environment via a multiplicity of routes from infected animals. Environmentally associated scrapie persists on farms when infected animals have been removed and is particularly resistant to disinfection. Infectivity within the farm is not adequately removed by current recommended guidelines for farm decontamination. We describe an in vitro method for modelling decontamination, specifically the removal of scrapie prions from the surface of concrete fomites within buildings that have housed scrapie infected animals. Concrete that had been spiked with low amounts of a diluted scrapie positive brain homogenate was sampled before and after decontamination. Extracts were used to seed a semi-quantitative serial protein misfolding cyclic amplification assay (sPMCA). We demonstrate that methods currently recommended for prion decontamination result in inadequate reduction of prion seeding activity within this in vitro assay. Effective treatment was achieved using repeat dosing of surfaces with 20,000 ppm available chlorine for 4 h.

Abstract

A partial wave analysis of pbar-p -> eta-eta-pizero data from the Crystal Barrel experiment is made in terms of s-channel resonances. The decay channels a_0(980)-eta, f_0(1770)-pi and f_0(2105)-pi provide evidence for two I = 1 J^{PC} = 0^{-+} resonances. The first has mass M =2360 +- 25 MeV and width Gamma = 300^{+100}_{-50} MeV, and the second M =2070 \pm 35 MeV, Gamma = 310^{+100}_{-50} MeV. There is also evidence for a J^{PC} = 2^{-+} state with M = 2005 +- 15 MeV and Gamma = 200 +- 40 MeV, decaying strongly to a_0(980)-pi., Comment: 11 pages, 6 figues

Abstract

An analysis of data on pbar-p -> eta-eta-pizero-pizero is presented at pbar beam momenta 600 to 1940 MeV/c. There is evidence for an I = 1, J^PC = 2^-+ resonance in eta-eta-pizero with mass M = 1880 +- 20 MeV and width 255 +- 45 MeV, decaying strongly a2(1320)-eta; it is too strong to be explained as the high mass tail of \pi_2(1670) -> a2(1320)-eta. There is tentative evidence also for weak decays to f_0(1500)\pi. It makes a natural partner to the eta 2(1860)., Comment: 12 pages, 6 figures

Abstract

Data on pbar-p -> 3eta for beam momenta 600--1940 MeV/c are presented. The strongest channel is f_0(1500)-eta from the initial pbar-p state 1S0. Together with eta-pizero-pizero data, the 3eta data determine the branching ratio BR[f_0(1500) -> eta-eta]/BR[f_0(1500) -> pizero-pizero] = 0.42+-0.09. They are consistent with a dominant contribution from an I=0, C=+1 J^{PC} = 0^{-+} resonance observed earlier in the eta-pizero-pizero data; from the combined eta-pizero-pizero and 3eta data, its mass is M = 2320 \pm 15 MeV and its width Gamma = 230+-35 MeV., Comment: One of 10 sets of data fitted to pbar-p in flight -> I=0 C=+1; 11 pages, 6 figures

Abstract

A partial wave analysis is presented of Crystal Barrel data on pbar-p -> pizero-pizero, eta-eta and eta-etaprime from 600 to 1940 MeV/c, combined with earlier data on d\sigma /d\Omega and P for pbar-p->piminus-piplus. The following s-channel I=0 resonances are identified: (i) J^{PC} = 5^{--} with mass and width (M,\Gamma) at (2295+-30,235^{+65}_{-40}) MeV, (ii) J^{PC} = 4^{++} at (2020+-12, 170+-15) MeV and (2300+-25, 270+-50) MeV, (iii) 3D3 JPC = 3^{--} at (1960+-15, 150+-25) MeV and (2210+-4$, 360+-55) MeV, and a 3G3 state at (2300 ^{+50}_{-80}, 340+-150) MeV, (iv) JPC = 2^{++} at (1910+-30, 260+-40) MeV, (2020+-30, 275+-35) MeV, (2230+-30, 245+-45) MeV, and (2300+-35, 290+-50) MeV, (v) JPC = 1^{--} at (2005+-40, 275+-75) MeV, and (2165+-40, 160 ^{+140}_{-70}) MeV, and (vi) JPC = 0^{++} at (2005+-30, 305+-50) MeV, (2105+-15, 200+-25) MeV, and (2320+-30, 175+-45) MeV. In addition, there is a less well defined 6^{++} resonance at 2485+-40 MeV, with Gamma = 410+-90 MeV. For every JP, almost all these resonances lie on well defined linear trajectories of mass squared v. excitation number. The slope is 1.10+-0.03 Gev^2 per excitation. The f_0(2105) has strong coupling to eta-\eta, but much weaker coupling to pizero-pizero. Its flavour mixing angle between q-qbar and s-sbar is (59-71.6)deg, i.e. dominant decays to s-sbar. Such decays and its strong production in pbar-p interactions strongly suggest exotic character., Comment: Makes available the combined fit to Crystal Barrel data on pbar-p -> 2-body final states. 29 pages, 11 figures.

Abstract

We confirm the existence of the two I G ( J PC ) = 0 + (0 ++ ) resonances f 0 (1370) and f 0 (1500) reported by us in earlier analyses. The analysis presented here couples the final states π 0 π 0 π 0 , π 0 π 0 η and π 0 ηη of p p annihilation at rest. It is based on a 3 × 3 K -matrix. We find masses and widths of M = (1390±30) MeV, Γ = (380±80) MeV; and M = (1500±10) MeV, Γ = (154 ± 30) MeV, respectively. The product branching ratios for the production and decay into π 0 π 0 and ηη of the f 0 (1500) are (1.27 ± 0.33) · 10 −3 and (0.60 ± 0.17) · 10 −3 , respectively.

Abstract

Twenty grey duiker (Sylvicapra grimmia) were blow-darted with a combination of ketamine and xylazine, resulting in a level of sedation adequate for capture and minor procedures in 13 of them (mean dosages: ketamine, 13.4 mg/kg; xylazine, 16.8 mg/kg). Sedation was judged to be inadequate in seven duikers (mean dosages: ketamine, 9.14 mg/kg; xylazine, 11.4 mg/kg). Sedation was reversed with atipamezole (mean dosage: 1.1 mg/kg) given as a split dose i.v. and i.m. in 19 duikers, resulting in variable reversal of sedation. Complications included inadequate sedation, trauma, hyperthermia, bradycardia, slow recovery, and one death.

Abstract

Comparative hematologic and plasma chemistry values were determined in 10 captive blue duikers (Cephalophus monticola) and 23 captive grey duikers (Sylvicapra grimmia). The animals included both males and females and ranged in age from 5 mo to 7 yr. Blue duikers were anesthetized with medetomidine and ketamine, and grey duikers were anesthetized with medetomidine and ketamine or xylazine and ketamine. Significant differences were found between grey and blue duikers for albumin, creatinine, creatine kinase, magnesium, and total bilirubin.

25. Reversible anesthesia of the blue duiker (Cephalophus monticola) with Medetomidine and Ketamine

Author

Bailey, T.A., Baker, C.A., Nicholls, P.K., Wilson, K., Bailey, T.A., Baker, C.A., Nicholls, P.K., and Wilson, K.

Abstract

Ten blue duiker (Cephalophus monticola) were blowdarted with a combination of ketamine and medetomidine, resulting in a level of sedation adequate for minor procedures in eight of the duikers (mean dosages: ketamine 2.2 mg/kg and medetomidine 190 µg/kg). Two duikers required an additional dose. Sedation was reversed with atipamezole (mean dosage: 0.95 mg/kg) given as a split dose i.v. and i.m. in all duikers, resulting in complete reversal of sedation. No anesthetic complications were seen in any of the duikers.

Abstract

Prominent KK¯ resonances observed in the in-flight annihilation of p¯p into K+K−π0 include f2(1270), f0(1500), f2′(1525), ϕ(1680)/ρ(1700) and a state at 1750 MeV/c2 consistent with f0(1710). The reaction cross sections σ(p¯p→X(K+K−)π0) are obtained by means of a partial wave analysis. When these are combined with known KK¯ partial widths, the resulting production rates of presumably non-nn¯ states, X=f0(1710) and f2′(1525), are found to be suppressed by an order of magnitude compared to f0(1500) and f2(1270), respectively.

29. An in vitro model for assessing effective scrapie decontamination

Author

Gough, Kevin C., Baker, C.A., Maddison, B.C., Gough, Kevin C., Baker, C.A., and Maddison, B.C.

Abstract

Scrapie infectivity enters the environment via a multiplicity of routes from infected animals. Environmentally associated scrapie persists on farms when infected animals have been removed and is particularly resistant to disinfection. Infectivity within the farm is not adequately removed by current recommended guidelines for farm decontamination. We describe an in vitro method for modelling decontamination, specifically the removal of scrapie prions from the surface of concrete fomites within buildings that have housed scrapie infected animals. Concrete that had been spiked with low amounts of a diluted scrapie positive brain homogenate was sampled before and after decontamination. Extracts were used to seed a semi-quantitative serial protein misfolding cyclic amplification assay (sPMCA). We demonstrate that methods currently recommended for prion decontamination result in inadequate reduction of prion seeding activity within this in vitro assay. Effective treatment was achieved using repeat dosing of surfaces with 20,000 ppm available chlorine for 4 h.

Abstract

The measurement of the neutron electric dipole moment (nEDM) constrains the contribution of CP-violating terms within both the Standard Model and its extensions. The experiment uses ultracold neutrons (UCN) stored in vacuum at room temperature. This technique provided the last (and best) limit by the RAL/Sussex/ILL collaboration in 2006: dn < 2:9 × 10⁻²⁶ e cm (90% C.L.). We aim to improve the experimental sensitivity by a factor of 5 within 2-3 years, using an upgrade of the same apparatus. We will take advantage of the increased ultracold neutron density at the Paul Scherrer Institute (PSI) and of a new concept including both, external magnetometers and a cohabiting magnetometer. In parallel, a next generation apparatus with two UCN storage chambers and an elaborate magnetic field control is being designed aiming to achieve another order of magnitude increase in sensitivity, allowing us to put a limit as tight as dn < 5 × 10⁻²⁸ e cm (95% C.L.), if not establishing a finite value.
