Cardiac arrest victims may experience transient brain hypoperfusion leading to delayed death of hippocampal CA1 neurons and cognitive impairment. We prevented this in adult rats by inhibiting the expression of transient receptor potential melastatin 7 (TRPM7), a transient receptor potential channel that is essential for embryonic development, is necessary(More)
Antibiotic resistance is spreading faster than the introduction of new compounds into clinical practice, causing a public health crisis. Most antibiotics were produced by screening soil microorganisms, but this limited resource of cultivable bacteria was overmined by the 1960s. Synthetic approaches to produce antibiotics have been unable to replace this(More)
In traumatic brain injury (TBI), neurons surviving the primary insult may succumb through poorly understood secondary mechanisms. In vitro, cortical neurons exposed to stretch injury exhibited enhanced vulnerability to NMDA, apoptotic-like DNA fragmentation, peroxynitrite (PN) formation, and cytoplasmic cytochrome c accumulation. Surprisingly, caspase-3(More)
We assessed the impact of vagus nerve stimulation on a cohort of patients with intractable epilepsy. A 1-year prospective trial of vagus nerve stimulation for intractable epilepsy was done in 26 patients. Seizure frequency, anti-epileptic drugs, and quality of life were assessed using QOLIE-89, ELDQOL, and a Likert scale of impact of treatment. Seizures(More)
RNA extracted from 120 leaf specimens from 17 plant species was pooled, and polyadenylated RNA species were sequenced together without barcoding in one lane using massively parallel sequencing technology. After analysis, complete or partial genome sequences representing 20 virus isolates of 16 polyadenylated RNA species were identified. In three cases, 2-3(More)
The cereal cyst nematode (CCN, Heterodera avenae) is a major pest of wheat (Triticum spp) that reduces crop yields in many countries. Cyst nematodes are obligate sedentary endoparasites that reproduce by amphimixis. Here, we report the first transcriptome analysis of two stages of H. avenae. After sequencing extracted RNA from pre parasitic infective(More)
To assess interspecies barriers to transmission of transmissible spongiform encephalopathies, we investigated the ability of disease-associated prion proteins (PrPd) to initiate conversion of the human normal cellular form of prion protein of the 3 major PRNP polymorphic variants in vitro. Protein misfolding cyclic amplification showed that conformation of(More)
Prion protein type and codon 129 genotype are thought to be major determinants of susceptibility and phenotype in human prion diseases. Using an in-vitro system (protein misfolding cyclic amplification) we have attempted to model human prion protein conversion using the abnormal prion protein associated with each of the major sporadic Creutzfeldt-Jakob(More)
An isolate of a new virus, Caladenia virus A (CalVA), was identified infecting Australian terrestrial orchids. The complete genome of 9,847 nucleotides encodes 11 gene products typical of most members of the family Potyviridae. Sequence comparisons of the polyprotein revealed that CalVA shared highest sequence identity (37.5-39.6 %) with members of the(More)
