To investigate molecular mechanisms controlling plant morphogenesis, we examined the morphology of primary roots of Arabidopsis thaliana and the organization of cortical microtubules in response to inhibitors of serine/threonine protein phosphatases and kinases. We found that cantharidin, an inhibitor of types 1 and 2A protein phosphatases, as previously(More)
There is growing epidemiological and molecular evidence that ABO blood group affects host susceptibility to severe Plasmodium falciparum infection. The high frequency of common ABO alleles means that even modest differences in susceptibility could have a significant impact on the health of people living in malaria endemic regions. We performed an(More)
The distribution of beta-hydroxybutyrate dehydrogenase (3-hydroxybutyrate dehydrogenase, EC 1.1.1.30) in the developing rat cerebellum has been determined using a histochemical method. Staining of Purkinje cells, particularly the soma, was seen at all ages examined. Intense staining of the proximal portions of Purkinje dendrites was noted at 8-11 days(More)
Trypsinization of coronal sections of rat brain, followed by incubation with the chelating agent, ethyleneglycol-bis(beta-aminoethyl ether)-N,N'-tetraacetic acid (EGTA), results in selective release of ciliated cuboidal ependymal cells which may be further purified by centrifugal methods. The isolated cells are motile, viable, and exhibit ultrastructure(More)
The prevalence of CD36 deficiency in East Asian and African populations suggests that the causal variants are under selection by severe malaria. Previous analysis of data from the International HapMap Project indicated that a CD36 haplotype bearing a nonsense mutation (T1264G; rs3211938) had undergone recent positive selection in the Yoruba of Nigeria. To(More)
Obstructive sleep apnea is a common disorder that causes patients to temporarily stop or decrease their breathing repeatedly during sleep. This results in fragmented, nonrestful sleep that can lead to symptoms such as morning headache and daytime sleepiness. Obstructive sleep apnea affects persons of all ages, with an increasing prevalence in those older(More)
A study was made of [3H]glycine uptake sites in a preparation greatly enriched in large pieces of the cerebellar glomeruli (glomerulus particles) and in morphologically well preserved slices of rat cerebellum. Electron microscopic autoradiography revealed that of the neurones in the cerebellar cortex only Golgi cells transported [3H]glycine at the low(More)
