Malaria caused by Plasmodium falciparum is a disease that is responsible for 880,000 deaths per year worldwide. Vaccine development has proved difficult and resistance has emerged for most antimalarial drugs. To discover new antimalarial chemotypes, we have used a phenotypic forward chemical genetic approach to assay 309,474 chemicals. Here we disclose(More)
Sequestration of Plasmodium falciparum-infected erythrocytes (Pf-IRBC) in postcapillary brain endothelium is a hallmark of cerebral malaria (CM) pathogenesis. There is a correlation between adherent Pf-IRBC and increased expression of intercellular cell adhesion molecule 1 (ICAM-1), which is also a receptor for Pf-IRBC on human brain microvascular(More)
OBJECTIVE To determine cocontraction's relation to strength and motor function in children with spastic cerebral palsy (CP). DESIGN Prospective evaluation with a convenience sample of 10 subjects. SETTING Pediatric rehabilitation center at a tertiary care hospital. PATIENTS Ten ambulatory children with spastic CP, mean age 5 to 14yrs. MAIN OUTCOME(More)
Neuropsychological assessments were performed in ninety-one de novo patients participating in the Sydney Multicentre Study of Parkinson's disease. Assessments were made at baseline and after 3 and 5 years. Performance at baseline and after 5 years was compared with controls. At baseline 37% of patients whose symptoms of Parkinson's disease had begun after(More)
The digestive vacuole of Plasmodium falciparum is the site of hemoglobin degradation, heme polymerization into crystalline hemozoin, and antimalarial drug accumulation. Antibodies identified histidine-rich protein II (HRP II) in purified digestive vacuoles. Recombinant or native HRP II promoted the formation of hemozoin, and chloroquine inhibited the(More)
Current therapy for glioblastoma multiforme is insufficient, with nearly universal recurrence. Available drug therapies are unsuccessful because they fail to penetrate through the region of the brain containing tumor cells and they fail to kill the cells most responsible for tumor development and therapy resistance, brain cancer stem cells (BCSCs). To(More)
BACKGROUND Current detection or screening for malaria infection necessitates drawing blood by fingerprick or venipuncture, which poses risks and limitations for repeated measurement. This study presents PCR detection of Plasmodium falciparum in human urine and saliva samples, and illustrates this potential application in genotyping malaria infections. (More)
Historically, the Chittagong Hill Tracts (CHT) of Bangladesh was considered hyperendemic for malaria. To better understand the contemporary malaria epidemiology and to develop new and innovative control strategies, comprehensive epidemiologic studies are ongoing in two endemic unions of Bandarban district of CHT. Within these studies entomological(More)
