Abstract β Amyloid protein (Aβ) and acetylcholinesterase (AChE) have been shown to be closely implicated in the pathogenesis of Alzheimer's disease. In current study, we investigated effects bis(7)‐tacrine, a novel dimeric AChE inhibitor, on Aβ‐induced neurotoxicity primary cortical neurons. Bis(7)‐tacrine, but not other inhibitors, elicited marked reduction both fibrillar soluble oligomeric forms apoptosis as evidenced by chromatin condensation DNA specific fragmentation. Both nicotinic...

The excessive activation of the <i>N</i>-methyl-d-aspartate receptor (NMDAR)/nitric oxide (NO) pathway has been proposed to be involved in neuropathology various neurodegenerative disorders. In this study, NO was found mediate glutamate-induced excitotoxicity primary cultured neurons. Compared with synthase (NOS) inhibitor, <i>N</i><sup>G</sup>-monomethyl-l-arginine (l-NMMA), and NMDAR antagonist memantine, bis(7)-tacrine more potent reducing NO-mediated release caused by glutamate....

Here we report that bis(7)-tacrine, a novel acetylcholinesterase inhibitor, exerts neuroprotective effects by inhibition of nitric oxide synthase. In cortical neurons at 12 days in vitro, bis(7)-tacrine concentration-dependently reduced cell death induced glutamate, beta-amyloid and L-arginine, but not sodium nitroprusside. N-monomethyl-L-arginine, synthase also prevented the former three types last type cytotoxicity; however, scavengers blocked all these insults, indicating mediated...

Quantile regression is an effective technique to quantify uncertainty, fit challenging underlying distributions, and often provide full probabilistic predictions through joint learnings over multiple quantile levels. A common drawback of these regressions, however, \textit{quantile crossing}, which violates the desirable monotone property conditional function. In this work, we propose Incremental (Spline) Functions I(S)QF, a flexible efficient distribution-free estimation framework that...

We propose Multivariate Quantile Function Forecaster (MQF$^2$), a global probabilistic forecasting method constructed using multivariate quantile function and investigate its application to multi-horizon forecasting. Prior approaches are either autoregressive, implicitly capturing the dependency structure across time but exhibiting error accumulation with increasing forecast horizons, or sequence-to-sequence models, which do not exhibit accumulation, also typically model steps. MQF$^2$...

Manufacturing industries have objectives of improving productivity and economic growth while simultaneously reducing energy consumption lessening environmental impact. Energy is a vital resource for the manufacturing industry. However, impacts are major concern use in manufacturing. It important to control manage way consumed reduce costs carbon emissions. This research focused on emissions industry South Africa from 1999 2015. Index decomposition analysis (IDA) historical trends were used...

We present PNKH-B, a projected Newton-Krylov method for iteratively solving large-scale optimization problems with bound constraints. PNKH-B is geared toward situations in which function and gradient evaluations are expensive, the (approximate) Hessian only available through matrix-vector products. This commonly case parameter estimation, machine learning, image processing. In each iteration, uses low-rank approximation of to determine search direction construct metric used line search. The...
