The adhesion modulation protein, AmpA localizes to an endocytic compartment and influences substrate adhesion, actin polymerization and endocytosis in vegetative Dictyostelium cells

BMC Cell Biology, 2012
Background AmpA is a secreted 24Kd protein that has pleiotropic effects on Dictyostelium development. Null mutants delay development at the mound stage with cells adhering too tightly to the substrate.

Intracerebroventricular administration of oxytocin and intranasal administration of the oxytocin derivative improve β‐amyloid peptide (25–35)‐induced memory impairment in mice

Neuropsychopharmacology Reports, Volume 42, Issue 4, Page 492-501, December 2022., 2022
Abstract Aim We previously reported that oxytocin, a peptide hormone, can reverse the β‐amyloid peptide (25–35) (Aβ25–35)‐induced impairments of the murine hippocampal synaptic plasticity. In this study, we examined the effects of oxytocin on the Aβ25–35‐induced impairment of cognitive behavior in murine in order to investigate the potential of ...

Sustainability‐Inspired Upcycling of Organophosphorus Pollutants into Phosphatic Fertilizer in a Continuous‐Flow Reactor

Angewandte Chemie, EarlyView.
First report of organophosphorus pollutants selective degradation, via the synergistic effect of peroxymonosulfate and sodium percarbonate, into phosphates that are continually converted into phosphatic fertilizer by struvite precipitation on a continuous‐flow reactor. Abstract With the increasing requirement for phosphorus resources and their shortage

Microglia shape presynaptic properties at developing glutamatergic synapses [PDF]

, 2019
Deficient neuron-microglia signaling during brain development is associated with abnormal synaptic maturation. However, the precise impact of deficient microglia function on synaptic maturation and the mechanisms involved remain poorly defined.

Structure Elucidation and Immunoactivity Study of Armillaria mellea Fruiting Body Polysaccharides

Separations, 2023
Polysaccharides are the main nutritional constituents in the Armillaria mellea fruiting bodies. The structure and immunoactivity of Armillaria mellea polysaccharide are valuable to be determined for development. In the present study, two polysaccharides,

Dissecting the Activation of AMPA Receptors [PDF]

Biophysical Journal, 2013
Ionotropic glutamate receptors are tetrameric ion channels that are activated by the neurotransmitter glutamate at excitatory synapses. It is known that after the binding of glutamate, the AMPA-subtype of glutamate receptors transits through distinct functional states to become fully activated, however, the conformations sampled by the tetramer during ...

Single NanoParticle Photothermal Tracking (SNaPT) of 5 nm gold beads in live cells [PDF]

Biophysical Journal 91, 12 (15/12/2006) 4598, 2007
Tracking individual nano-objets in live cells during arbitrary long times is an ubiquitous need in modern biology. We present here a method for tracking individual 5 nm gold nanoparticles on live cells. It relies on the photothermal effect and the detection of the Laser Induced Scattering around a NanoAbsorber (LISNA).

How feedback inhibition shapes spike-timing-dependent plasticity and its implications for recent Schizophrenia models [PDF]

, 2011
It has been shown that plasticity is not a fixed property but, in fact, changes depending on the location of the synapse on the neuron and/or changes of biophysical parameters.

Glyphosate dynamics prediction in a soil under conventional and no-tillage systems during the crop cycle [PDF]

Revista Brasileira de Ciência do Solo, 2020
Simulation models are efficient tools to predict the fate of different solutes in agricultural soils. This work aimed to compare measured and predicted glyphosate and AMPA (aminomethyl phosphonic acid; its main metabolite) contents in a soil under no ...

AMPA Receptor Activation [PDF]

Neuron, 2004
AMPA receptors are tetramers assembled as a dimer-of-dimers with a 2-fold rotational symmetry in their extracellular domains. Two papers in this issue of Neuron, by Horning and Mayer and Sobolevsky et al., provide complementary data that extend this view and highlight the role of dimers in channel gating.
