A novel process driving Alzheimer's disease validated in a mouse model: Therapeutic potential.

Introduction: The neuronal mechanism driving Alzheimer's disease (AD) is incompletely understood.

Methods: Immunohistochemistry, pharmacology, biochemistry, and behavioral testing are employed in two pathological contexts-AD and a transgenic mouse model-to investigate T14, a 14mer peptide, as a key signaling molecule in the neuropathology.

Results: T14 increases in AD brains as the disease progresses and is conspicuous in 5XFAD mice, where its immunoreactivity corresponds to that seen in AD: neurons immunoreactive for T14 in proximity to T14-immunoreactive plaques.

The Potential Impact of Hydrocarbons on Mussels in Port au Port Bay, Newfoundland.

Since 2012, the scallop fishery in Port au Port Bay, Newfoundland, Canada has experienced a drastic decline, while no decline was observed in adjacent St. George's Bay. Local fishermen have raised concerns about an abandoned oil exploration well in the Port au Port Bay.

Isolation of nitrate-reducing bacteria from an offshore reservoir and the associated biosurfactant production.

Biosurfactant producing nitrate-reducing bacteria (NRB) in anaerobic reservoir environments are closely associated with souring (HS) control in the offshore oil and gas industry. Five NRB strains were screened from offshore produced water samples and all were identified as . Their biosurfactant producing abilities when fed on either glucose or glycerol media were investigated.

Unusual metabolic diversity of hyperalkaliphilic microbial communities associated with subterranean serpentinization at The Cedars.

Water from The Cedars springs that discharge from serpentinized ultramafic rocks feature highly basic (pH=~12), highly reducing (E<-550 mV) conditions with low ionic concentrations. These conditions make the springs exceptionally challenging for life. Here, we report the metagenomic data and recovered draft genomes from two different springs, GPS1 and BS5.

Phospholipid fatty acid (PLFA) analysis for profiling microbial communities in offshore produced water.

A method based on phospholipid fatty acid (PLFA) analysis for profiling microbial communities in offshore produced water was optimized. The operation parameters affecting final PLFA profiling performance from the solid phase extraction (SPE) purification and fatty acid methyl esters (FAMEs) yielding process were investigated. Under the selected conditions, 92.
