Remyelination is a regenerative process in the central nervous system (CNS) that produces new myelin sheaths from adult stem cells. The decline in remyelination that occurs with advancing age poses a significant barrier to therapy in the CNS, particularly for long-term demyelinating diseases such as multiple sclerosis (MS). Here we show that remyelination(More)
The lack of therapies for progressive multiple sclerosis highlights the need to understand the regenerative process of remyelination that can follow CNS demyelination. This involves an innate immune response consisting of microglia and macrophages, which can be polarized to distinct functional phenotypes: pro-inflammatory (M1) and anti-inflammatory or(More)
PURPOSE The proliferation of new blood vessels in the retina is a leading cause of vision impairment. Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox) is involved in cell signaling for ischemia-induced angiogenesis, but its role in retinal neovascularization is unclear. We have analyzed the dependence of retinal neovascularization on the(More)
Despite advances in management and treatment, retinopathy of prematurity remains a major cause of childhood blindness. Evidence for a genetic basis for susceptibility to retinopathy of prematurity is examined, including the influences of sex, ethnicity, and ocular pigmentation. The role of polymorphisms is explored in the genes for vascular endothelial(More)
The growing burden of the rapidly ageing global population has reinvigorated interest in the science of ageing and rejuvenation. Among organ systems, rejuvenation of the central nervous system (CNS) is arguably the most complex and challenging of tasks owing, among other things, to its startling structural and functional complexity and its restricted(More)
Recent evidence suggests a genetic component to oxygen-induced retinopathy (OIR), a robust experimental model of human retinopathy of prematurity. OIR lends itself well to quantitative analysis of gene expression in rodents with well-defined genetic backgrounds. Such analysis by real-time reverse transcription polymerase chain reaction (RT-PCR) requires the(More)
BACKGROUND The aim of this study is to examine the relationship between sociodemographic factors and utilization of eye care services in patients presenting in acute angle-closure (AAC). DESIGN A hospital-based retrospective, case-control study. PARTICIPANTS Fifty-five patients consecutively presenting to the emergency department of the Royal Victorian(More)
Hybridomas were derived from lipopolysaccharide-reactive splenic B cells of adult germ-free BALB/c mice fed a chemically defined ultrafiltered "antigen-free" diet (GF-CD) and from splenic B cells of 5-day-old conventional (CV-NEO) BALB/c mice. The monoclonal antibodies (mAb) from both collections of hybridomas were tested for reactivity against a large(More)
PURPOSE To examine the susceptibilities of different rat strains to oxygen-induced retinopathy, a model of human retinopathy of prematurity. METHODS Litters of newborn rats of five inbred strains (Fischer 344 [F344], Dark Agouti [DA], Sprague-Dawley [SD], Wistar-Furth [WF], Lewis [LEW]) and one outbred strain (Hooded Wistar [HW]) were maintained in room(More)
