gastrointestinal duplications are rare congenital malformations and they may vary greatly in presentation, size, location and symptoms. the presence of ectopic gastric mucosa (egm) in them is not common and they are difficult to diagnose prior to surgery. we present the case of a child with long intestinal duplication with ectopic gastric mucosa who presented with just severe anaemia and delaye...

BACKGROUND Wrist blood pressure (BP) devices have physiological limits with regards to accuracy, therefore they were not preferred for home BP monitoring. However some wrist devices have been successfully validated using established validation protocols. Therefore this study assessed the reproducibility of wrist home BP measurement with position sensor and automatic data storage. METHODS To c...

Pressure and Pulse Pressure on Stroke To the Editor: Using 4.7 years of follow-up data on 2311 Western, hypertensive subjects, Verdecchia and colleagues1 reported that 24-hour ambulatory mean blood pressure (BP), not pulse pressure (PP), was an independent predictor of stroke risk. Because the association between BP and stroke risk has been reported to be much steeper in Eastern populations tha...

In a collection of spontaneous mutants of Chinese hamster ovary cells selected for deficiency in adenine phosphoribosyl transferase (aprt) activity, one was detected having not only a deletion of aprt coding sequences but also an apparent amplification of remaining sequences. The HindIII fragment bearing the novel joint was cloned and sequenced revealing a complex gene rearrangement. A deletion...

Gamma-glutamylcysteine synthetase encoded by GSH1 is the rate-limiting enzyme in the biosynthesis of glutathione and trypanothione in Leishmania. Attempts to generate GSH1 null mutants by gene disruption failed in Leishmania infantum. Removal of even a single allele invariably led to the generation of an extra copy of GSH1, maintaining two intact wild-type alleles. In the second and even third ...

In previous studies, of which several were underpowered, the relation between cardiovascular outcome and blood pressure (BP) variability was inconsistent. We followed health outcomes in 8938 subjects (mean age: 53.0 years; 46.8% women) randomly recruited from 11 populations. At baseline, we assessed BP variability from the SD and average real variability in 24-hour ambulatory BP recordings. We ...

CTX-M-15-producing Klebsiella pneumoniae and Escherichia coli emerged recently in Cameroon. CTX-M-15 was encoded by two different multiresistance plasmids, of which one carried an ISEcp1-bla(CTX-M-15) element flanked by a 5-bp target site duplication and inserted within a Tn2-derived sequence. A truncated form of this element in the second plasmid was identified.

The dopamine D4 receptor (DRD4) is a member of the D2-like dopamine receptor family. Polymorphisms at the DRD4 gene have been examined for association with a wide range of neuropsychiatric disorders and normal behavioral variation. The DRD4 gene is unusual in its high amount of expressed polymorphism in humans. Here we study the identification of a polymorphic tandem duplication of 120 bp locat...

Wallerian degeneration is the degeneration of the distal stump of an injured axon. It normally occurs over a time course of around 24 hr but it is delayed in the slow Wallerian degeneration mutant mouse (C57BL/Wlds) for up to 3 weeks. The gene, which protects from rapid Wallerian degeneration, Wld, previously has been mapped to distal chromosome 4. This paper reports the fine genetic mapping of...
