Patients infected with the malaria parasite Plasmodium falciparum may develop a diffuse reversible encephalopathy, termed cerebral malaria. It is unclear how the intraerythrocytic parasite, which sequesters in the cerebral microvasculature but does not enter the brain parenchyma, induces this neurological syndrome. Adhesion of parasitized red blood cells in(More)
Immunohistochemical techniques have been used to investigate specific patterns of potentially reversible cellular injury, DNA damage, and apoptosis in the brainstems of Vietnamese patients who died of severe Plasmodium falciparum malaria. The degree and pattern of neuronal and glial stress responses were compared between patients with cerebral and(More)
So-called bottom-up fabrication methods aim to assemble and integrate molecular components exhibiting specific functions into electronic devices that are orders of magnitude smaller than can be fabricated by lithographic techniques. Fundamental to the success of the bottom-up approach is the ability to control electron transport across molecular components.(More)
In animals, high doses of intramuscular artemether and artemotil have been shown to cause an unusual pattern of selective damage to certain brainstem nuclei, especially those implicated in hearing and balance. We aimed to investigate whether a similar pattern arises in human adults. We examined the brainstems of adults who died after treatment with high(More)
Disruption of axonal transport may represent a final common pathway leading to neurological dysfunction in cerebral malaria (CM). Calpains are calcium (Ca2+)-activated cysteine proteases which have been implicated in axonal injury in neurological diseases of various aetiologies. In this study we examined the association between mu- and m-calpain, the(More)
In Baz Luhrmann's <i>Australia</i> the main protagonists drive a massive herd of cattle through the Australian outback. To extend the on-set cattle herd with up to 5000 digital bovines we developed a crowd system based on a <i>Autodesk Maya</i> integration of our <i>Venom</i> infrastructure. This sketch will give an overview of the crowd workflow and how it(More)

National Laboratory for providing CdSe nanocrystals and useful discussions. T. Rieker, NSF (formerly University of New Mexico), performed early XRD experiments. Climate policy decisions are being made despite layers of uncertainty. Such decisions directly influence the potential for " dangerous anthropogenic interference with the climate system. " We mapped(More)
