Here, we assessed the sulfated derivative of the microbial polysaccharide gellan gum and derivatives of λ and κ-carrageenans for their ability to inhibit Plasmodium falciparum 3D7 and Dd2 growth and invasion of red blood cells in vitro. Growth inhibition was assessed by means of flow cytometry after a 96-h exposure to the inhibitors and invasion inhibition was assessed by counting ring parasite...
We present the first diffraction-limited specklemasking bispectrum observations of the central part of the Red Rectangle at optical wavelengths (λ ∼ 656 nm and λ ∼ 800 nm). The results confirm infrared observations which show that the object is a bipolar nebula. The dark lane separating the two lobes is probably produced by an obscuring dust disk slightly inclined with respect to the line of si...
We have previously described a recombinase-mediated gene stacking system in which the Cre recombinase is used to remove lox-site flanked DNA no longer needed after each round of Bxb1 integrase-mediated site-specific integration. The Cre recombinase can be conveniently introduced by hybridization with a cre-expressing plant. However, maintaining an efficient cre-expressing line over many generat...
Hydrocephalus is a common and variegated pathology often emerging in newborn children after genotoxic insults during pregnancy (Hicks and D'Amato, 1980). Cre recombinase is known to have possible toxic effects that can compromise normal cell cycle and survival. Here we show, by using three independent nestin Cre transgenic lines, that high levels of Cre recombinase expression into the nucleus o...
A study of the angular size-redshift relation for models in which Λ decays as the energy density Abstract. By modifying the Chen and Wu ansatz, we have investigated some Friedmann models in which Λ varies as ρ. In order to test the consistency of the models with observations, we study the angular size-red-shift relation for 256 ultracompact radio sources selected by Jackson and Dodgson. The ang...
We show, by explicit computation, that bare lattice perturbation theory in the 2-dimensional O(n) nonlinear sigma–models with super– instanton boundary conditions is divergent in the limit of an infinite number of points |Λ|. This is the analogue of David’s statement that renormalized perturbation theory of these models is infra-red divergent in the limit where the physical size of the box tend...
To discuss the optoelectronic effect on resistive random access memory (RRAM) devices, the bipolar switching properties and electron-hole pair generation behavior in the transparent indium tin oxide (ITO) electrode of Gd:SiO2 thin films under the ultraviolet (λ = 400 nm) and red-light (λ = 770 nm) illumination for high resistance state (HRS)/low resistance state (LRS) was observed and investiga...
