Point-of-care microfluidic assays for the developing world face uncontrolled storage temperatures that can destroy functionality of on-card reagents. In development of such assays [1], we report a method for dry storage and microfluidic rehydration of immunochemical reagents in a sugar-based matrix on porous media. Using gold-antibody conjugates against the malarial antigen Plasmodium falciparu...

Cerebral malaria is a medical emergency. All patients with Plasmodium falciparum malaria with neurologic manifestations of any degree should be urgently treated as cases of cerebral malaria. Pathogenesis of cerebral malaria is due to damaged vascular endothelium by parasite sequestration, inflammatory cytokine production and vascular leakage, which result in brain hypoxia, as indicated by incre...

We have identified a simple tandem repeat DNA polymorphism in the human glycogen synthase gene of the form (TG)n. This DNA polymorphism has 10 alleles and a heterozygosity of 0.82 and can be easily typed using the polymerase chain reaction. It has been localized within the framework genetic map of chromosome 19 and is located in the region of the apolipoprotein C-II and histidine-rich calcium-b...

Keratohyalin granules were isolated in the native form from the epidermis of newborn rats by the use of citric acid and a detergent. The isolated granules revealed a fine granular substructure in the electron microscope similar to that seen in situ. Analyses of amino acids by automated column-chromatography showed that proline and cystine are present in large proportions whereas histidine is pr...

Impaired sarcoplasmic reticulum (SR) Ca release has been suggested to contribute to the depressed cardiac function in heart failure. The release of Ca from the SR may be regulated by the ryanodine receptor, triadin, junctin, calsequestrin, and a histidine-rich, Ca-binding protein (HRC). We observed that the levels of HRC were reduced in animal models and human heart failure. To gain insight int...
