We investigated the modulation of voltage-gated Ca channels by nitric oxide (NO) in isolated salamander retinal ganglion cells with the goals of determining the type of Ca channel affected and the signaling pathway by which modulation might occur. The NO donors, S-nitroso-N-acetyl-penicillamine (SNAP, 1 mM) and S-nitroso-cysteine (1 mM) induced modest increases in the amplitude of Ca channel cu...

This Chapter covers the emissions of airborne particulate matter (PM) from road transport which are due to vehicle tyre and brake wear (SNAP code 070700) and road surface wear (SNAP code 070800). PM emissions from vehicle exhaust are not included. The focus is on primary non-exhaust particles in other words those particles emitted directly as a result of the wear of surfaces and not those resul...

The SNAP was modified to SNAP ST (Idexx Laboratories Inc., Westbrook, ME), a new 7-8 minute test which no longer requires the use of an incubator. This new test was validated at ILVO-T&V according to Commission Decision 2002/657/EC and the CRL Guidelines for the Validation of Screening Methods (Anon., 2010). The SNAP ST is very specific as an interference was only caused by clavulanic acid, a β...

We have hypothesized that the plasma membrane protein components of the exocytotic soluble N-ethylmaleimide-sensitive factor attachment protein (SNAP) receptor (SNARE) complex, syntaxin 1A and SNAP-25, distinctly regulate different voltage-gated K+ (Kv) channels that are differentially distributed. Neuroendocrine islet cells (alpha, beta, delta) uniformly contain both syntaxin 1A and SNAP-25. H...

Many safety net programs issue benefits as monthly lump-sum payments. We investigate how the timing of Supplemental Nutrition Assistance Program (SNAP) benefit issuance affects food purchases and incidence transfer. Using scanner data from a large sample grocery stores state time variation in SNAP schedules, we document large, SNAP-induced intramonth cycles expenditures. However, find that reta...

A snap-stabilizing protocol, starting from any arbitrary initial configuration, always behaves according to its specification. In [10], Cournier and al. present the first snap-stabilizing Propagation of Information with Feedback (PIF) protocol in arbitrary networks. But, in order to achieve the desirable property of snap-stabilization, the algorithm needs the knowledge of the exact size of the ...

The SNARE (soluble N-ethylmaleimide-sensitive fusion protein-attachment protein receptor) protein SNAP-25 (25 kDa synaptosome-associated protein) is essential for regulated exocytosis in neuronal and neuroendocrine cells. Whereas the majority of SNARE proteins contain transmembrane domains, SNAP-25 is instead anchored to membranes by the palmitoylation of a central cysteine-rich region. In this...

BACKGROUND The Supplemental Nutrition Assistance Program (SNAP) is the largest federal nutrition assistance program. In recent years, SNAP participation rates increased during times of economic hardship. OBJECTIVE We examined whether household SNAP participation was associated with adiposity and metabolic risk factors in a representative sample of low-income US adults. DESIGN A cross-sectio...

The " ideal " plastic assembly would have all components joined right in the molding shop. Press or snap fitted together by operators at the machine, finished products would be ready for packaging and shipment. While assembly operations in the automotive , machinery or appliance industries are usually a bit more complex, subassemblies frequently will employ snap and press fits—especially when a...
