Analysis of Sugar Component of a Hot Water Extract from Arabidopsis thaliana Pollen Tubes Using GC-EI-MS

open access: yesBio-Protocol, 2015
Extraction with hot water is the oldest and simplest method used to recover pectin from an alcohol insoluble residue extract, although this method has not been widely used for the cell wall analysis of pollen tube, a model used to study cell wall.

Characterization of a GDP-Fucose Transporter and a Fucosyltransferase Involved in the Fucosylation of Glycoproteins in the Diatom Phaeodactylum tricornutum

open access: yesFrontiers in Plant Science, 2019
Although Phaeodactylum tricornutum is gaining importance in plant molecular farming for the production of high-value molecules such as monoclonal antibodies, little is currently known about key cell metabolism occurring in this diatom such as protein ...

In Vitro Proliferation and Production of Cytokine and IgG by Human PBMCs Stimulated with Polysaccharide Extract from Plants Endemic to Gabon

open access: yesMolecules, 2014
Polysaccharides were extracted from seven plants endemic to Gabon to study their potential immunological activities. Peripheral blood mononuclear cell (PBMC) (5 × 105 cells/mL) proliferation, cytokine and immunoglobulin G (IgG) assays were performed ...

Direct sequencing of measles virus complete genomes in the midst of a large-scale outbreak.

open access: yesPLoS ONE, 2021
Measles outbreaks escalated globally despite worldwide elimination efforts. Molecular epidemiological investigations utilizing partial measles virus (MeV) genomes are challenged by reduction in global genotypes and low evolutionary rates.

Scattering of 12-Mev Protons, 24-Mev Deuterons, and 48-Mev Alpha Particles by Beryllium [PDF]

open access: yesPhysical Review, 1958
A beryllium target has been bombarded with 12-Mev protons, 24-Mev deuterons, and 48-Mev alpha particles. With the three projectiles, the differential cross sections for inelastic scattering leading to the formation of the 2.43-Mev state have been measured. Application of inelastic-scattering theory leads to the assignment for this level, spin $\frac{5}{

A Simple Protocol for the Immunolabelling of Arabidopsis Pollen Tube Membranes and Cell Wall Polymers

open access: yesBio-Protocol, 2015
The pollen tube, a fast tip-growing cell, is an excellent model to study membrane and cell wall biosynthesis. Here, we describe a simple protocol using an easy to use device to perform immunofluorescence labelling of pollen tube membrane and cell wall ...

Neonatal stroke enhances interaction of microglia-derived extracellular vesicles with microglial cells

open access: yesNeurobiology of Disease, 2021
Microglial cells support brain homeostasis under physiological conditions and modulate brain injury in a context-dependent and brain maturation-dependent manner. Microglial cells protect neonatal brain from acute stroke.

Diatom-Specific Oligosaccharide and Polysaccharide Structures Help to Unravel Biosynthetic Capabilities in Diatoms

open access: yesMarine Drugs, 2015
Diatoms are marine organisms that represent one of the most important sources of biomass in the ocean, accounting for about 40% of marine primary production, and in the biosphere, contributing up to 20% of global CO2 fixation.

FDG at 7.8 MeV [PDF]

open access: yesAIP Conference Proceedings, 2017
I here report the fundamental performance of a new generation of compact medical cyclotrons for hospital-based PET tracer manufacture, exemplified with the FDG production numbers achieved by the first prototype of the GE GenTrace cyclotron. The proton energy is 7.8 MeV.
