Age-related macular degeneration (AMD) is the leading cause of central vision loss worldwide. Drusen accumulation is the major pathological hallmark common to both dry and wet AMD. Although activation of the immune system has been implicated in disease progression, the pathways involved are unclear. Here we show that drusen isolated from donor AMD eyes… (More)
Age-related macular degeneration (AMD) is the leading cause of legal blindness in elderly individuals in the developed world, affecting 30-50 million people worldwide. AMD primarily affects the macular region of the retina that is responsible for the majority of central, color and daytime vision. The presence of drusen, extracellular protein aggregates that… (More)
The inflammasome is a molecular platform formed by activation of an innate immune pattern recognition receptor seed, such as NLRP3. Once activated, NLRP3 recruits the adapter ASC (apoptosis-related speck-like protein containing a caspase recruitment domain), which in turn recruits procaspase-1. Procaspase-1 autocatalyzes its cleavage and activation,… (More)
Traumatic brain injury is the leading cause of death in children and young adults globally. Malignant cerebral oedema has a major role in the pathophysiology that evolves after severe traumatic brain injury. Added to this is the significant morbidity and mortality from cerebral oedema associated with acute… (More)
IMPORTANCE OF THE FIELD Efficient systemic delivery of low-molecular-mass therapeutics to neuronal tissue remains a central issue not only to drug development but also to the chronic treatment of a range of neurodegenerative disorders. AREAS COVERED IN THIS REVIEW This review discusses the potential of using RNA interference to modulate tight junction… (More)
PURPOSE Age-related macular degeneration is the most common form of central retinal blindness in the elderly. Of the two end stages of disease, neovascular AMD-although the minority form-is the most severe. Current therapies are highly successful at controlling progression of neovascular lesions; however, a significant number of patients remain refractory… (More)
We describe a procedure for controlled, periodic, reversible modulation of selected regions of the blood-brain barrier (BBB) or the inner-blood-retina barrier (iBRB) based on incorporation into an AAV-2/9 vector of a doxycycline-inducible gene encoding shRNA targeting claudin-5, one of 30 or so proteins constituting the BBB and iBRB. The vector may be… (More)
Plasmonics-active gold nanostars exhibiting strong imaging contrast and efficient photothermal transduction were synthesized for a novel pulsed laser-modulated plasmonics-enhanced brain tumor microvascular permeabilization. We demonstrate a selective, optically modulated delivery of nanoprobes into the tumor parenchyma with minimal off-target distribution.
Age-related macular degeneration (AMD) is the leading cause of central vision loss worldwide and while polymorphisms in genes associated with the immune system have been identified as risk factors for disease development, the underlying pathways and mechanisms involved in disease progression have remained unclear. In AMD, localised inflammatory responses… (More)
A novel coupled-segment quadrifilar helical antenna is presented, for which a shorter axial length than a conventional quadrifilar helix is obtained. The coupled segment technique allows for modification of the radiation patterns to a shape which is more desirable for satellite communications systems, such as Globalstar.
