Plasmodium spp. and Toxoplasma gondii are important human and veterinary pathogens. These parasites possess an unusual double membrane structure located directly below the plasma membrane named the inner membrane complex (IMC). First identified in early electron micrograph studies, huge advances in genetic manipulation of the Apicomplexa have allowed the visualization of a dynamic, highly struc...

1025 COVER False-colored electron micrograph of the rough endoplasmic reticulum (ER, light green), which consists of elongated membrane structures studded with ribosomes (dark green dots) and is adjacent to the nuclear envelope (dark green, right). The ER is the entry portal for newly synthesized membrane and secretory proteins (circular mitochondrion: ~0.49 micrometers wide). Two Reviews (page...

computer simulation, liquid crystals, displays We present a novel lattice modelling approach for the behaviour of nematic liquid crystals in cells. Our model includes elastic deformation energy, finite surface anchoring and applied voltages. These have been implemented and tested in a twodimensional model. We present results from this model for various analytic test cases and for a real scannin...

In the article cited above, the authors discovered an inadvertent error in Fig. 4A (bottom right panel). The micrograph in the 2008 article for the 1Ad-Cont-siRNA condition is a duplicate, shifted slightly, of the control micrograph above it in the top right panel (nontransduced condition). This error arose through mislabeling of the original micrographs. Figure 4A is reproduced below with the ...

The misfit dislocations and strain fields at a Ge/Si heterostructure interface were investigated experimentally using a combination of high-resolution transmission electron microscopy and quantitative electron micrograph analysis methods. The type of misfit dislocation at the interface was determined to be 60° dislocation and 90° full-edge dislocation. The full-field strains at the Ge/Si hetero...

In this paper, electrodeposition and visible light photocurrent responses of Zn-doped Cu2O were reported. The process was conducted with different deposition time to study the growth deposit. structural investigation elemental analysis performed on an energy dispersive X-ray spectrometer diffractometer, respectively. crystal studied from micrograph obtained using a field emission scanning elect...

The effect of Si doping on the stability, electronic structure, and electron transport properties of boron nitride (BN) monolayer has been investigated by density functional theory method. Unique features in the electron transport characteristics consisting of a significant enhancement of current at the Si site, diode-like asymmetric current-voltage response, and negative differential resistanc...

Thymus is a primary lymphoid organ in fish. This gland is situated at the upper most part of the middorsolateral region of the opercular cavity, close to the base of 3 rd and 4 th gill arches. Aplocheilus panchax (Weight-2.5gm. Length-7.5cm.) a fresh water teleost belonging to the Order – Cyprinidontiformes, family – Aplocheilidae is examined under light and transmission electron microscopes (L...

Hooks and other sub-surface features in continuous-cast ultralow-carbon steel samples were examined using optical microscopy, electron backscattering diffraction, energy dispersive X-ray spectroscopy, and electron probe microanalysis techniques. Special etching reagents revealed dendrites growing from both sides of the line of hook origin. This line was found to represent the frozen meniscus an...
