Haemophilia B mutations in a complete Swedish population sample : a test of new strategy for the genetic counselling of diseases with high mutational heterogeneity

Carrier and prenatal diagnosis based on the identification of the gene defect (direct diagnosis) increases the proportion of haemophilia B families that can be offered precise genetic counselling from the 50-60% attainable by DNA markers, to 100%, and they also provide information on the molecular biology of the disease. We propose that in order to maximize the practical and scientific benefits of

Taking the history in patients with swallowing disorders : an international multidisciplinary survey

Purpose: Clinical assessment of swallowing disorders (dysphagia) requires accurate and comprehensive medical history-taking to further tailor the diagnostic work-up, but functional health care questionnaires show a large variability and various limitations. The aim of this study was to assess the way in which international swallowing experts from various disciplines asses swallowing problems in or

Exploring the Loading Capacity of Generation Six to Eight Dendronized Polymers in Aqueous Solution

Aspects of size, structural (im)perfection, inner density, and guest molecule loading capacity of dendronized polymers (DPs) of high generation (6≤g≤8) in aqueous solution are studied using electron paramagnetic resonance spectroscopy on amphiphilic, spin-labeled guest molecules. The results show that the interior of the charged DPs is strongly polar, especially in comparison to their lower genera

Likelihood Ratio Tests for a Unit Root in Panels with Random Effects

Because of the fixed heterogeneity of their models, most panel unit root tests impose restrictions on the rate at which the number of time periods, T, and the number of cross-section units, N, go to infinity. A common example of such a restriction isN/T→0, which in practice means that T≫N, a condition that is not always met. In the current paper the heterogeneity is given a parsimonious random eff

Protein-dependent membrane interaction of a partially disordered protein complex with oleic acid : Implications for cancer lipidomics

Bovine α-lactalbumin (BLA) forms cytotoxic complexes with oleic acid (OA) that perturbs tumor cell membranes, but molecular determinants of these membrane-interactions remain poorly understood. Here, we aim to obtain molecular insights into the interaction of BLA/BLA-OA complex with model membranes. We characterized the folding state of BLA-OA complex using tryptophan fluorescence and resolved res

Optimization of the short-circuit current in an InP nanowire array solar cell through opto-electronic modeling

InP nanowire arrays with axial p-i-n junctions are promising devices for next-generation photovoltaics, with a demonstrated efficiency of 13.8%. However, the short-circuit current in such arrays does not match their absorption performance. Here, through combined optical and electrical modeling, we study how the absorption of photons and separation of the resulting photogenerated electron-hole pair

A GPS-Based Methodology to Analyze Environment-Health Associations at the Trip Level : Case-Crossover Analyses of Built Environments and Walking

Environmental health studies have examined associations between context and health with individuals as statistical units. However, investigators have been unable to investigate momentary exposures, and such studies are often vulnerable to confounding from, for example, individual-level preferences. We present a Global Positioning System (GPS)-based methodology for segmenting individuals' observati

Exploration of physical and chemical cues on retinal cell fate

Identification of the key components in the physical and chemical milieu directing donor cells into a desired phenotype is a requirement in the investigation of bioscaffolds for the advancement of cell-based therapies for retinal neurodegeneration. We explore the effect of electrospun poly-ε-caprolactone (PCL) fiber scaffold topography and functionalization and culture medium, on the behavior of m
