We report on 0.3–10 keV X-ray observations by the Chandra X-ray Observatory of the fields of 22 sources that were discovered as hard X-ray (20–100 keV) sources by the INTEGRAL satellite (“IGR” sources). The observations were made during Chandra’s 9th observing cycle, and their purpose is to localize the sources and to measure their soft X-ray spectra in order to determine the nature of the sour...

We report on the results of observations of hard X-ray sources in the Galactic plane with the Chandra X-ray Observatory. The hard X-ray “IGR” sources were discovered by the INTEGRAL satellite, and the goals of the Chandra observations are to provide sub-arcsecond localizations to obtain optical and infrared counterparts and to provide constraints on their 0.3–10 keV spectra. We obtained relativ...

Hard X-ray imaging of the Galactic plane by the INTEGRAL satellite is uncovering large numbers of 20– 100 keV “IGR" sources. We present results from Chandra, INTEGRAL, optical, and IR observations of 4 IGR sources: 3 sources in the Norma region of the Galaxy (IGR J16195–4945, IGR J16207–5129, and IGR J16167– 4957) and one that is closer to the Galactic center (IGR J17195–4100). In all 4 cases, ...

The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is discovering hundreds of new hard X-ray sources, many of which remain unidentified. We report on optical spectroscopy of five such sources for which X-ray observations at lower energies (∼0.5–10 keV) and higher angular resolutions than INTEGRAL have allowed for unique optical counterparts to be located. We find that IGR J16426+653...

The ESA γ-ray telescope, INTEGRAL, is detecting relatively more intrinsically rare cataclysmic variables (CVs) than were found by surveys at lower energies. Specifically, a large fraction of the CVs that are INTEGRAL sources consists of asynchronous polars and intermediate polars (IPs). IP classifications have been proposed for the majority of CVs discovered by INTEGRAL, but, in many cases, the...

AIMS To study the relationship between thioredoxin-interacting protein (TXNIP) and pancreatic β-cell function in patients with impaired glucose regulation and patients with both impaired glucose regulation and hypertriglyceridemia. METHODS We analyzed a population of 90 patients with impaired glucose regulation (IGR), 87 patients with IGR and hypertriglyceridemia, and 90 subjects with normal ...

BACKGROUND & OBJECTIVES In fly management programme chemicals are extensively used. Combined use of insect growth regulator (IGR) and parasitoids would yield a better reduction in fly density, as exposure of fly larvae to sub lethal dose of IGR enhances pupal duration and thereby increases the exposure time for parasitism. The objective of the present study was to explore the additive effect of...

The rapid increase in Mycobacterium tuberculosis resistance to ethambutol (EMB) threatens the diagnosis and treatment of tuberculosis (TB). We investigated the role of mutations in the embC-embA intergenic region (IGR) in EMB-resistant clinical strains from east China. A total of 767 M. tuberculosis clinical strains were collected and analyzed for their drug susceptibility to EMB using the MGIT...

The positive-stranded RNA genome of Plautia stali intestine virus (PSIV) has an internal ribosome entry site (IRES) in an intergenic region (IGR). The IGR-IRES of PSIV initiates translation of the capsid protein by using CAA, the codon for glutamine. It was previously reported (J. Sasaki and N. Nakashima, J. Virol. 73:1219-1226, 1999) that IGR-IRES extended by several nucleotides into the capsi...

OBJECTIVE This study determined the prevalence and factors associated with peripheral neuropathy (PN) in subjects with diabetes mellitus, impaired glucose regulation (IGR), and normal glucose tolerance (NGT) in a community-based Chinese population. RESEARCH DESIGN AND METHODS A total of 2035 subjects in Shanghai were classified as having NGT, IGR, or diabetes. All subjects underwent complete ...
