OBJECTIVES Simultaneous Non-contrast Angiography and intraPlaque hemorrhage (SNAP) technique was recently proposed for joint MRA and intraplaque hemorrhage (IPH) imaging. The purpose of this study is to validate SNAP's MRA performance in patients with suspected intracranial artery disease. METHODS SNAP and time-of-flight (TOF) techniques with matched field of view and resolution were applied ...

The AMP-activated protein kinase (AMPK) regulates metabolism in normal and pathological conditions and responds to nutrients, hormones, anti-diabetic drugs and physical exercise. AMPK is activated by the kinase LKB1 and inactivated by phosphatases whose identities remain uncertain. Here we show that AMPK associates with α-SNAP, an adapter that enables disassembly of cis-SNARE complexes formed d...

High quality water is less available for agriculture and thus farmers often use saline water, that affects crop growth and yield. Snap bean (Phaseolus vulgaris) is sensitive to soil and water salinity, and also to heat stress. The aim of this research is to evaluate if a postponed transplant (high temperature stress) of snap bean can influence growth and yield under saline conditions. Snap bean...

Synaptosomal-associated protein of 25 kDa (SNAP-25) is a key molecule in the soluble N-ethylmaleimide-sensitive factor attachment protein (SNARE) complex mediating fast Ca(2+)-triggered release of hormones and neurotransmitters, and both splice variants, SNAP-25a and SNAP-25b, can participate in this process. Here we explore the hypothesis that minor alterations in the machinery mediating regul...

Synaptosomal-associated protein of 25 kDa (SNAP-25) is a palmitoylated membrane protein essential for neurotransmitter release from synaptic terminals. We used neuronal cell lines to study the biosynthesis and posttranslational processing of SNAP-25 to investigate how palmitoylation contributes to the subcellular localization of the protein. SNAP-25 was synthesized as a soluble protein that und...

During myelin formation, vast amounts of specialized membrane proteins and lipids are trafficked toward the growing sheath in cell surface-directed transport vesicles. Soluble N-ethylmaleimide-sensitive factor (NSF) attachment proteins (SNAPs) are important components of molecular complexes required for membrane fusion. We have analyzed the expression profile and molecular interactions of SNAP-...

OBJECTIVE This article investigates the association between Supplemental Nutrition Assistance Program (SNAP) participation and child food security by using data from the largest national survey of the food security of SNAP participants to date. METHODS The analysis used a survey of nearly 3000 households with children and a quasi-experimental research design that consisted of 2 sets of compar...

In this study we compared a commercial enzyme linked immunosorbent assay (ELISA) rapid test (Snap CLATK Canine Leishmania Antibody Test Kit, IDEXX-Snap) with indirect immunofluorescence assay (IFA) and Western blot (WB) for the detection of Leishmania infantum antibodies in dogs. In total sera from 234 dogs were collected: 59 positives and 51 doubtful sera (IFA 1:40-1:80) from an L. infantum en...

SNAP-tag and CLIP-tag protein labeling systems enable the specific, covalent attachment of molecules, including fluorescent dyes, to a protein of interest in live cells. These systems offer a broad selection of fluorescent substrates optimized for a range of imaging instrumentation. Once cloned and expressed, the tagged protein can be used with a variety of substrates for numerous downstream ap...

Botulinum neurotoxins (BoNTs) block neurotransmitter release through their specific proteolysis of the proteins responsible for vesicle exocytosis. Paradoxically, two serotypes of BoNTs, A and E, cleave the same molecule, synaptosome-associated protein with relative molecular mass 25K (SNAP-25), and yet they cause synaptic blockade with very different properties. Here we compared the action of ...
