Primordial germ cell (PGC) migration in zebrafish is directed by the chemokine SDF-1a that activates its receptor CXCR4b. Little is known about the molecular mechanisms controlling the distribution of this chemoattractant in vivo. We demonstrate that the activity of a second SDF-1/CXCL12 receptor, CXCR7, is crucial for proper migration of PGCs toward their(More)
The polymorphic fungus Candida albicans is a member of the normal human microbiome. In most individuals, C. albicans resides as a lifelong, harmless commensal. Under certain circumstances, however, C. albicans can cause infections that range from superficial infections of the skin to life-threatening systemic infections. Several factors and activities have(More)
Lafora disease is an inborn error of carbohydrate metabolism with storage of a polyglucosan in various tissues including brain and liver. Recently, distinctive histopathological changes in liver have been emphasized, and the diagnosis has been confirmed by the relatively simple procedure of percutaneous liver biopsy. We utilized this technique to study(More)
Candida albicans frequently causes superficial infections by invading and damaging epithelial cells, but may also cause systemic infections by penetrating through epithelial barriers. C. albicans is an unusual pathogen because it can invade epithelial cells via two distinct mechanisms: induced endocytosis, analogous to facultative intracellular(More)

Cerebellar liponeurocytoma is a rare tumor of the posterior fossa that has many morphological similarities to medulloblastoma and neurocytoma. Recently the World Health Organization working group for classification of central nervous system neoplasms adopted the term "cerebellar liponeurocytoma" to provide a unified nomenclature for a tumor variously(More)
The ability of pathogenic microorganisms to assimilate essential nutrients from their hosts is critical for pathogenesis. Here we report endothelial zinc sequestration by the major human fungal pathogen, Candida albicans. We hypothesised that, analogous to siderophore-mediated iron acquisition, C. albicans utilises an extracellular zinc scavenger for(More)
The Ebola virus disease epidemic in West Africa is the largest on record, responsible for over 28,599 cases and more than 11,299 deaths. Genome sequencing in viral outbreaks is desirable to characterize the infectious agent and determine its evolutionary rate. Genome sequencing also allows the identification of signatures of host adaptation, identification(More)
Spontaneous (non-traumatic) symptomatic intracerebral hemorrhage is a devastating form of stroke, with very high overall mortality and morbidity. Even with the best current medical or surgical treatment, outcomes still remain poor. By contrast with ischemic stroke, the incidence of intracerebral hemorrhage is not decreasing. Indeed, the incidence of(More)
The clinical histories, histologic features, and immunohistochemical staining patterns for glial fibrillary acidic protein, vimentin, p53, and epidermal growth factor receptor (EGFR) of three cases of congenital glioblastoma multiforme are given and previous case reports are reviewed. Of the three cases reported in this series, two have had long-term(More)
