Detection of HTTex1p by western blot and immunostaining of HD human and mouse brain using neo-epitope antibody P90 highlights impact of CAG repeat expansion on its size, solubility, and response to MSH3 silencing.

has been identified in human and mouse HD brain as the pathogenic exon 1 mRNA generated from aberrant splicing between exon 1 and 2 that contributes to aggregate formation and neuronal dysfunction (Sathasivam et al., 2013). Detection of the HTT exon 1 protein (HTTex1p) has been accomplished with surrogate antibodies in fluorescence-based reporter assays (MSD, HTRF), and immunoprecipitation assays, in HD postmortem cerebellum and knock-in mice but direct detection by SDS-PAGE and western blot assay has been lacking.

Aortic valve leaflet assessment to inform novel bioinspired materials: Understanding the impact of collagen fibres on the tissue's mechanical behaviour.

Aortic stenosis is a prevalent disease that is treated with either mechanical or bioprosthetic valve replacement devices. However, these implants can experience problems with either functionality in the case of mechanical valves or long-term durability in the case of bioprosthetic valves. To enhance next generation prosthetic valves, such as biomimetic polymeric valves, an improved understanding of the native aortic valve leaflet structure and mechanical response is required to provide much needed benchmarks for future device development.

Association of Low Hospital Birth Volume and Adverse Short-Term Outcomes for Neonates Treated with Therapeutic Hypothermia in Rural States.

Objective: We hypothesized that outborn neonates from smaller birth volume hospitals would have more frequent adverse short-term outcomes following therapeutic hypothermia (TH).

Study Design: Multicenter retrospective study comparing outcomes for small (<500 births/year), medium (501-1500 births/year), and large (>1500 births/year) hospitals in Northern New England. Multivariable logistic regression assessed the combined outcome of death/severe gray matter injury on MRI, controlling for encephalopathy severity and time to initiation of TH.

Alterations of upper-extremity functional muscle networks in chronic stroke survivors.

Current clinical assessment tools don't fully capture the genuine neural deficits experienced by chronic stroke survivors and, consequently, they don't fully explain motor function throughout everyday life. Towards addressing this problem, here we aimed to characterise post-stroke alterations in upper-limb control from a novel perspective to the muscle synergy by applying, for the first time, a computational approach that quantifies diverse types of functional muscle interactions (i.e.
