Large swaths of the nutrient-poor surface ocean are dominated numerically by cyanobacteria (Prochlorococcus), cyanobacterial viruses (cyanophage), and alphaproteobacteria (SAR11). How these groups thrive in the diverse physicochemical environments of different oceanic regions remains poorly understood. Comparative metagenomics can reveal adaptive responses(More)
The cognitive deficits associated with schizophrenia commonly include impairment in attention, which may contribute to difficulties with learning, memory, and executive function. This study evaluated the effectiveness of computer-aided training of attentional skills in schizophrenia. Two groups of schizophrenic subjects (9 men and 1 woman) were matched for(More)
In 2001, an international surveillance initiative was established, utilising a validated larval development inhibition assay to track the susceptibility of cat flea isolates to imidacloprid. In 2009, an Australian node was incorporated into the programme, joining laboratories in the United States and Europe. Field isolates of Ctenocephalides felis eggs were(More)
Eastern forests of the US are valued both as a carbon sink and a wood resource. The amount of biomass that can be harvested sustainably from this biome for bioenergy without compromising the carbon sink is uncertain. Using past literature and previously validated models, we assessed four scenarios of biomass harvest in the eastern US: partial harvests of(More)
Experimental studies have shown that deposition of reactive nitrogen is an important driver of plant community change, however, most of these experiments are of short duration with unrealistic treatments, and conducted in regions with elevated ambient deposition. Studies of spatial gradients of pollution can complement experimental data and indicate whether(More)
Despite its proven efficacy and safety, electroconvulsive therapy (ECT) continues to be a controversial treatment. Ongoing scrutiny is therefore particularly important. We reviewed 315 patients who received 3903 ECT treatments over a five year period, and found a gradual decline in the use of ECT, due mainly to a reduction in ECT for schizophrenic patients.(More)
