The ability to grow as a biofilm can facilitate survival of bacteria in the environment and promote infection. To better characterize biofilm formation in the pathogen Clostridium difficile, we established a colony biofilm culture method for this organism on a polycarbonate filter, and analyzed the matrix and the cells in biofilms from a variety of clinical(More)
This study presents the Edinburgh Cognitive and Behavioural ALS Screen (ECAS), developed for ALS patients with physical disability for use by health care professionals. The screen is designed to detect the specific profile of cognition and behaviour changes in ALS and to differentiate it from other disorders. Forty-eight ALS patients (none with evident(More)
Several studies have shown that people with Alzheimer's disease (AD) demonstrate difficulties in doing two things at once or 'dual-tasking' and that this dual task impairment is insensitive to normal ageing, chronic depression or prodromal conditions like Mild Cognitive Impairment. It is not known, however, if this impairment is specific to AD, or also(More)
Variation in the genetic risk(s) of developing Parkinson's disease (PD) undoubtedly contributes to the subsequent phenotypic heterogeneity. Although patients with PD who undergo deep brain stimulation (DBS) are a skewed population, they represent a valuable resource for exploring the relationships between heterogeneous phenotypes and PD genetics. In this(More)
We previously reported the de novo design of combinatorial libraries of proteins targeted to fold into four-helix bundles. The sequences of these proteins were designed using a binary code strategy in which each position in the linear sequence is designated as either polar or nonpolar, but the exact identity of the amino acid at each position is varied(More)
Although several studies have shown that dual-tasking ability is impaired in Alzheimer's disease (AD), the stage at which this deficit manifests remains unclear. This study investigated if a new paper-and-pencil assessment of dual-tasking ability could distinguish between AD, mild cognitive impairment (MCI) and normal ageing in a sample of 50 people with(More)
Academic success or ability is often assessed through peer review or the seemingly more objective method of citation ratings. However, citation ratings may be more objective in that they offer a more automated or mechanical method of assessing quality, but it does not necessarily follow that these ratings provide an assessment of genuine scientific impact.(More)
Although several studies have described dual-tasking ability in normal aging, Mild Cognitive Impairment and Alzheimer's disease, no normative data for dual-task performance exist. Dual-tasking ability of 436 healthy individuals, aged 16-88 years, was assessed using a new paper-and-pencil dual-task paradigm. In this study, no age effect was detected,(More)
Our objective was to assess the validity of the Edinburgh Cognitive and Behaviour ALS Screen (ECAS), a multi-domain screen designed to detect cognitive deficits in patients with motor disorders. Forty ALS patients (without pre-diagnosed dementia) and 40, age-, gender- and education-matched healthy controls were recruited. All participants underwent(More)
Diagnosis of Alzheimer's disease (AD) requires evidence of progressive decline in cognitive function. However, many tests used to assess cognitive function suffer from considerable practice effects, reducing their reliability. Several studies have reported that the ability to do two things at once, or dual tasking, is impaired in AD, but unaffected by(More)
