Fibrils composed of tau protein are a pathological hallmark of several neurodegenerative disorders including Alzheimer's disease (AD). Here we show that when recombinant tau protein is seeded with paired helical filaments (PHFs) isolated from AD brain, the amyloid formed shares many of the structural features of AD PHFs. In contrast, tau amyloids formed(More)
The present study constitutes the first attempt to construct a polytene chromosome map of an Anastrepha species, Anastrepha ludens (Loew), a major agricultural pest. The mitotic karyotype has a diploid complement of 12 acrocentric chromosomes, including five pairs of autosomes and an XX/XY sex chromosome pair. The analysis of salivary gland polytene(More)
Protein fusion tags are indispensible tools used to improve recombinant protein expression yields, enable protein purification, and accelerate the characterization of protein structure and function. Solubility-enhancing tags, genetically engineered epitopes, and recombinant endoproteases have resulted in a versatile array of combinatorial elements that(More)
INTRODUCTION Functional abdominal symptoms are very common and account for nearly two million primary care consultations in Britain every year and produce significant morbidity. The aims of this study were to evaluate the impact of two self-help interventions on consultation rates and symptom severity in patients with a primary care diagnosis of irritable(More)
The limitations to high-level expression of integral membrane proteins are not well understood. The human A(2)a adenosine receptor (A(2)a) and mouse Substance P receptor (SPR) were individually expressed in S. cerevisiae to identify potential cellular bottlenecks for G-protein coupled receptors. In the yeast system, A(2)a was not N-linked glycosylated but(More)
G-protein coupled receptors (GPCRs) are seven transmembrane helical proteins involved in cell signaling and response. They are targets for many existing therapeutic agents, and numerous drug discovery efforts. Production of large quantities of these receptors for drug screening and structural biology remains challenging. To address this difficulty, we(More)
OBJECTIVES To determine if a whole systems approach to self-management improves clinical outcomes and leads to cost-effective use of NHS services. DESIGN Nineteen hospitals were randomised to 10 control sites and nine intervention sites. Consultants from intervention sites received training in patient-centred care before recruitment and introduced the(More)
In eukaryotes, secretory proteins are folded and assembled in the endoplasmic reticulum (ER). Many heterologous proteins are retained in the ER due to suboptimal folding conditions. We previously reported that heterologous secretion of Pyrococcus furiosus beta-glucosidase in Saccharomyces cerevisiae resulted in the accumulation of a large fraction of(More)
BACKGROUND Ulcerative colitis is managed mainly in secondary care by regular outpatient reviews done by specialist clinicians. Alternatives would be to discharge patients to primary care or to provide open-access clinics, but neither of these options reduce patients' dependency on doctors or allow patients' involvement in disease management. We did a(More)
Misfolding and misassembly of proteins are major problems in the biotechnology industry, in biochemical research, and in human disease. Here we describe a novel approach for reversing aggregation and increasing refolding by application of hydrostatic pressure. Using P22 tailspike protein as a model system, intermediates along the aggregation pathway were(More)
