To drive malaria eradication, new medicines that target all stages of the malaria life cycle are needed. In their study, Meister et al. used thousands of A. stephensi mosquitos to identify chemical cla...

The electrospinning was applied to fabricate aligned nanofibers in a magnetic field. Fe2O3 nanoparticles were added PVDF/Zn(CHCOOH)2 solution, and heat treatment of the nanofiber mats made produce PVDF/Fe2O3 containing ZnO nanoparticles. Hierarchical composites obtained via facile hydro-thermal growth process, where radially oriented nanorods found. morphology as-synthesized samples investigate...

Blood-Contacting Surfaces In article number 2102214, Jun Ki Hong, Anna Waterhouse, Chiara Neto, and co-workers report that tethered-liquid perfluorocarbons show low adhesion of blood components. The cover image is a scanning electron micrograph revealing minimal platelets after incubation in human whole blood. bumpy background the tethered-perfluorocarbon layer which stabilizes liquid perfluoro...

This report presents an alternative technique of application of contrast agent in vivo, i.e. before sampling. By this new method the electron micrograph of tissue sections have an acceptable contrast compared to other methods and present no artifact of precipitation on sections. Another advantage is that a small amount of contrast is needed to get a good result given that most of them are expen...

www.sciencemag.org SCIENCE VOL 325 28 AUGUST 2009 1037 COVER Pseudocolored scanning electron micrograph (magnification ~34,000x) of the surface of mouse airway epithelia showing cilia protruding from epithelial cells; short protrusions in the foreground are microvilli from a nonciliated cell. In human airway epithelia, these motile cilia bear receptors that detect bitter compounds and signal th...

Carphology 70 Carphology by A Fo Ben Cover image Brain infl ammation (meningoencephalitis). Coloured transmission electron micrograph (TEM) of several Naegleria fowleri protozoan microbes (yellow) in the brain. A blood vessel is seen running from bottom right to centre left with red blood cells (red) and white blood cells (pale blue). N. fowleri caused the meningoencephalitis, which is the infl...

The top electrodes which simultaneously pump the phase-shifted and non-phase-shifted region are then deposited by evaporation and lift-off processes. Fig. 2 shows the scanning electron micrograph (S...

Ultrafiltration using polyethersulfone-membranes was evaluated as an efficient and preferred method for purifying Cowpea Chlorotic Mottle Virus (CCMV). Cesium chloride (CsCl) ultracentrifugation and ultrafiltration protocols are described, and comparative UV-spectroscopic and electron micrograph results are presented. CCMV purified by ultrafiltration are shown to be equivalent to CCMV purified ...

www.sciencemag.org SCIENCE VOL 339 11 JANUARY 2013 115 COVER A yin-yang symbol superimposed on a scanning electron micrograph of a mouse tissue alveolar macrophage (diameter: ~18 micrometers). Macrophages are immune cells that mediate infl ammation, but they often play protective roles as well. Several age-related chronic diseases—such as metabolic syndrome, cardiovascular disease, and neurodeg...
