Rapid Communication: The Progesterone Receptor (PGR) Gene Maps to Porcine Chromosome 9p13-p11 by a Rodent-Porcine Somatic Cell Hybrid Panel
Genus and Species. Sus scrofa. Locus. Pig Progesterone Receptor ( PGR) gene. Source and Description of Primers. Oligonucleotide primers were designed from a partial pig PGR cDNA sequence (Genbank accession no. S49016) with inferred intron-exon boundary information from humans (Misrahi et al., 1993). The primers were designed to span the intron between exons 7 and 8 of the PGR gene
Issues Associated with Late Onset Deafness
Late deafened adults are individuals who have acquired a severe or profound hearing loss in adulthood. They comprise the largest proportion of the deaf population, yet little information is available about their condition and its influence on them. The current article will discuss problems experienced by late deafened adults, psychosocial aspects associated with late hearing loss, and suggestions that might assist professionals in working with these individuals. In addition to a literature review, personal accounts of the first author will be provided
Rapid Communication: MspI Restriction Fragment Length Polymorphism at the Swine MYF6 Locus
Source and Description of Probe. A 1,296-bp rat cDNA clone for MRF4 (also called MYF6) was excised from the EcoRI site of the plasmid pBluescript KS+ (Rhodes and Konieczny, 1989
Rapid Communication: Restriction Fragment Length Polymorphisms at the Porcine Transporter Associated with Antigen Processing 1 (TAP1) Locus
Source and Description of Probe. A 2.7-kb human cDNA clone for TAP1 was excised from the XbaI site of the plasmid pRSV.5neo (Spies et al., 1990). Method of Detection. Hybridizations were performed at 65°C for 16 to 20 h (10% dextran sulfate, 7% SDS, .263 M NazHP04, 1% BSA, 1 mM EDTA, 100 pg/mL sonicated denatured salmon sperm DNA). Final washes were done at 65°C in .7x SSC, .5% SDS for 15 to 20 min
The pre-outburst flare of the A 0535+26 August/September 2005 outburst
We study the spectral and temporal behavior of the High Mass X-ray Binary A
0535+26 during a `pre-outburst flare' which took place ~5 d before the peak of
a normal (type I) outburst in August/September 2005. We compare the studied
behavior with that observed during the outburst. We analyse RXTE observations
that monitored A 0535+26 during the outburst. We complete spectral and timing
analyses of the data. We study the evolution of the pulse period, present
energy-dependent pulse profiles both at the initial pre-outburst flare and
close to outburst maximum, and measure how the cyclotron resonance-scattering
feature (hereafter CRSF) evolves. We present three main results: a constant
period P=103.3960(5)s is measured until periastron passage, followed by a
spin-up with a decreasing period derivative of Pdot=(-1.69+/-0.04)x10^(-8)s/s
at MJD 53618, and P remains constant again at the end of the main outburst. The
spin-up provides evidence for the existence of an accretion disk during the
normal outburst. We measure a CRSF energy of Ecyc~50kev during the pre-outburst
flare, and Ecyc~46kev during the main outburst. The pulse shape, which varies
significantly during both pre-outburst flare and main outburst, evolves
strongly with photon energy.Comment: 4 pages, 4 figures, accepted for publication in A&A Letters. To be

Multiple Cyclotron Lines in the Spectrum of 4U 0115+63
We report phase resolved spectroscopy of the transient accreting pulsar,
4U0115+63. For the first time, more than two cylotron resonance scattering
features are detected in the spectrum of an X-ray pulsar. The shape of the
fundamental line appears to be complex, and this is in agreement with
predictions of Monte-Carlo models. As in other pulsars, the line energies and
optical depths are strong functions of pulse phase. One possible model for this
is an offset of the dipole of the neutron star magnetic field.Comment: 5 pages. To appear in "Proceedings of the 5th Compton Symposium
Discovery of a New 89 Second X-ray Pulsar XTE J1906+09
We report on the discovery of a new pulsating X-ray source during Rossi X-ray
Timing Explorer observations of a low galactic latitude field centered at RA
(J2000) = 19 hr 05 m 43 s and Dec (J2000) = +08 deg 58 arcmin 48 arcsec.
Significant pulsations were detected by both the PCA and HEXTE instruments
aboard RXTE at a fundamental period of 89.17 +/- 0.02 seconds, with higher
harmonics also visible in the 2-10 keV power spectrum. The folded lightcurve
from the source is multiply peaked at lower energies, and changes to single
peaked morphology above ~20 keV. The phase averaged spectrum from the source is
well fit by strongly absorbed power law or thermal bremsstrahlung spectral
models of photon index 1.9 +/- 0.1 or temperature 19.5 +/- 4.6 keV,
respectively. The mean neutral hydrogen column density is approximately 10^23
cm^-2, suggesting a distance of >10 kpc to the source and a minimum 2-10 keV
X-ray luminosity of 2*10^{35} ergs s^{-1}. By comparison with other pulsars
with similar periods and luminosities, we suggest that XTE J1906+09 has a
supergiant companion with an underfilled Roche lobe. We speculate further that
one of the M stars in a peculiar M star binary system may be the companion.Comment: 14 pages, 2 figures. Accepted by ApJ Letter
