Monomethylamine (MMA, CH3NH2) can be used as a carbon and nitrogen source by many methylotrophic bacteria. Methylobacterium extorquens DM4 lacks the MMA dehydrogenase encoded by mau genes, which in M. extorquens AM1 is essential for growth on MMA. Identification and characterization of minitransposon mutants with an MMA-dependent phenotype showed that strain DM4 grows with MMA as the sole sourc...

Adalimumab (ADA) is applied to induce remission in patients with Crohn's disease (CD) naïve to chimeric anti-tumor necrosis factor-α (anti-TNF-α), infliximab or patients with loss of response to scheduled maintenance infliximab. Adsorptive granulocyte and monocyte apheresis (GMA) depletes elevated/activated myeloid lineage leucocytes as sources of inflammatory cytokines and has been used to tre...

Large deformability and high sensitivity is difficult to be realized simultaneously in flexible sensors. Herein, taking advantage of the permittivity highly active surfaces ultrasmall barium titanate nanoparticles (BT NPs) stretchability p(BA-GMA) elastomer matrix, we propose a high-performance soft stretchable sensor. The addition BT NPs can not only increase capacitance polyacrylate-matrix co...

Auf der GMA 2014 erwarten Sie ein hochkarätiges wissenschaftliches Programm und herausragende, international renommierte Keynote-Sprecher, die sich mit zentralen, aktuellen Fragen der Lehrforschung auseinandersetzen werden: Jonathan Silverman von der Universität Cambridge untersucht den Zusammenhang zwischen kommunikativen Fähigkeiten und qualitativ hochwertiger Gesundheitsversorgung, Geoff Nor...

BACKGROUND The reasons for surgical failure in 30% of patients with unilateral mesial temporal lobe epilepsy (MTLE) are still unclear. We investigated if different outcomes could be associated to different patterns of subtle gray matter atrophy (GMA) and white matter atrophy (WMA), and searched for postoperative magnetic resonance imaging (MRI) changes. METHODS We studied 69 controls and 67 o...

Welding processes that generate fumes containing toxic metals, such as hexavalent chromium (Cr(VI)), manganese (Mn), and nickel (Ni), have been implicated in lung injury, inflammation, and lung tumor promotion in animal models. While federal regulations have reduced permissible worker exposure limits to Cr(VI), this is not always practical considering that welders may work in confined spaces an...

Three experiments were conducted to compare the effects of feeding blends of grains naturally contaminated with Fusarium mycotoxins on brain regional neurochemistry of laying hens, turkey poults, and broiler breeder hens. In Experiment 1, thirty-six 45-wk-old laying hens were fed diets including the following for 4 wk: 1) control, 2) contaminated grains, and 3) contaminated grains + 0.2% polyme...

Hybrids made from an alkyd resin and an acrylic copolymer can potentially combine the desired properties of each component. Alkyd/acrylic hybrid latex particles were synthesized via miniemulsion polymerization and used to create films at room temperature. Comparisons of the alkyd auto-oxidative cross-linking rates and the associated network development are made between two alkyd resins (with di...

The effect of various dimethacrylates on the structure and properties of homo- and copolymer networks was studied. The 2,2-bis-[4-(2-hydroxy-3- methacryloyloxypropoxy)phenyl]-propane) (Bis-GMA), triethylene glycol dimethacrylate (TEGDMA) and 1,6-bis-(methacryloyloxy-2-ethoxycarbonylamino)-2,4,4-trimethylhexane (HEMA/TMDI), all popular in dentistry, as well as five urethane-dimethacrylate (UDMA)...

The study objective was to prepare biodegradable branched dextran microspheres encapsulated with His-tagged interferon-alpha (BDM-hIFN-alpha) and evaluate its activity in vitro and in vivo. The glycidyl methacrylate derivatized dextrans (Dex-GMA) as precursor was primarily synthesized by substituting hydroxyl groups of either the branched or linear type of dextran with GMA. Dex-GMA microspheres...
