BACKGROUND We and others have previously reported significant changes in chloride transport after cationic-lipid-mediated transfer of the cystic fibrosis transmembrane conductance regulator (CFTR) gene to the nasal epithelium of patients with cystic fibrosis. We studied the safety and efficacy of this gene transfer to the lungs and nose of patients with(More)
BACKGROUND Increasing the activity of defective cystic fibrosis transmembrane conductance regulator (CFTR) protein is a potential treatment for cystic fibrosis. METHODS We conducted a randomized, double-blind, placebo-controlled trial to evaluate ivacaftor (VX-770), a CFTR potentiator, in subjects 12 years of age or older with cystic fibrosis and at least(More)
Tumour necrosis factor (TNF)-alpha is associated with childhood wheezing. A genetic predisposition to increased TNF-alpha production, influenced by single nucleotide gene polymorphisms, may be important. Frequencies of TNF-alpha-308G/A and lymphotoxin (LT)-alpha+252G/A polymorphisms were compared in 115 asthmatic children, 55 wheezy infants and 156 control(More)
The response of two populations of neurones in the substantia nigra (nigro-striatal compacta neurones and reticulata neurones) to microelectrophoretically administered putative neurotransmitters and stimulation of the ipsilateral striatum has been investigated in anaesthetized rats. There were marked differences between compacta and reticulata neurones in(More)
We use both large and small animal models in our pre-clinical evaluation of gene transfer agents (GTAs) for cystic fibrosis (CF) gene therapy. Here, we report the use of a large animal model to assess three non-viral GTAs: 25 kDa-branched polyethyleneimine (PEI), the cationic liposome (GL67A) and compacted DNA nanoparticle formulated with polyethylene(More)
Chromosome 6 is a metacentric chromosome that constitutes about 6% of the human genome. The finished sequence comprises 166,880,988 base pairs, representing the largest chromosome sequenced so far. The entire sequence has been subjected to high-quality manual annotation, resulting in the evidence-supported identification of 1,557 genes and 633 pseudogenes.(More)
Cone beam CT (CBCT) is becoming an increasingly utilized imaging modality for dental examinations in the UK. Previous studies have presented little information on patient dose for the range of fields of view (FOVs) that can be utilized. The purpose of the study was therefore to calculate the effective dose delivered to the patient during a selection of CBCT(More)
Gene amplification using polymerase chain reaction (PCR) was carried out on DNA samples from a total of 92 normal subjects and 52 subjects with myotonic dystrophy (DM) from European and Japanese populations, to determine the copy number of the CTG repeat associated with DM for each group. In the two populations, the number of repeats on normal chromosomes(More)
Properties of a new potent antagonist acting selectively at N-methyl-D-aspartate (NMDA) type excitatory amino acid receptors are described. This compound, 3-((+/-)-2-carboxypiperazin-4-yl)propyl-1-phosphonic acid (CPP) is more potent than all previously reported NMDA antagonists in depressing mammalian spinal neuronal responses (cat and immature rat), in(More)
The reference sequence for each human chromosome provides the framework for understanding genome function, variation and evolution. Here we report the finished sequence and biological annotation of human chromosome 1. Chromosome 1 is gene-dense, with 3,141 genes and 991 pseudogenes, and many coding sequences overlap. Rearrangements and mutations of(More)
