OBJECTIVE To define the clinical, radiologic, and genetic features of periventricular heterotopia (PH) with Ehlers-Danlos syndrome (EDS). METHODS Exonic sequencing and single stranded conformational polymorphism (SSCP) analysis was performed on affected individuals. Linkage analysis using microsatellite markers on the X-chromosome was performed on a(More)
Cyanobacteria respond to environmental stress conditions by adjusting their photosynthesis machinery. In Synechococcus sp. PCC 7942, phycobilisome degradation and other acclimation responses after nutrient or high-light stress require activation by the orphan response regulator NblR, a member of the OmpR/PhoB family. Although NblR contains a putative(More)
Cyanobacteria respond to environmental stress conditions by adjusting its photosynthesis machinery. When subjected to nutrient and high light stress, Synechococcus sp. PCC 7942 and other non-diazotrophic cyanobacteria degrade their phycobilisome, the light-harvesting complexes for photosynthesis. Phycobilisome degradation requires convergence of multiple(More)
AIM The morbidity of anastomotic dehiscence may be mitigated by a defunctioning stoma, but it is unclear if it is required for most low rectal anastomoses. Preoperative risk factors leading to anastomotic complications and the indications for faecal diversion have yet to be clearly defined. METHOD Using the American College of Surgeons-National Surgical(More)
The nucleotide (nt) sequence of a 1332-bp fragment of Streptomyces alboniger DNA containing the gene (dmpM), which encodes an O-demethyl puromycin O-methyltransferase (DMPM), has been determined. The dmpM gene contains a 1131-nt open reading frame which encodes a polypeptide of Mr 40,303; this is consistent with the 44 +/- 2.5- and 160-kDa sizes of the DMPM(More)
The coexistence of pregnancy and idiopathic hypertrophic subaortic stenosis is a potentially dangerous combination. We report a 23-year-old white woman with idiopathic hypertrophic subaortic stenosis and pregnancy who presented with severe symptoms (Class IV) and modest outflow obstruction associated with marked mitral regurgitation. After delivery, the(More)
PURPOSE To determine the spectrum and frequency of specific computed tomographic (CT) findings in the acute period after endovascular repair of abdominal aortic aneurysm (AAA). MATERIALS AND METHODS CT images obtained 1--3 days after endograft placement were evaluated in 88 patients. The images were analyzed for stent position, appearance of endograft(More)
A gene (bls) encoding a blasticidin S-acetyltransferase from Streptoverticillum sp. JCM4673 was cloned in the Streptomyces plasmid pIJ702 and expressed in S. lividans 1326. Four of the recombinant plasmids contained a common 1129-bp BclI-PstI DNA fragment, which by subcloning experiments was shown to carry the bls gene. Sequencing of the 1129-bp BclI-PstI(More)
