rMSCs; and (b) labeled rMSCs. GAG stains red, nuclei black, and the cytoplasm green. Labeled cells show positive GAG staining (arrows), as well as extracellular iron; (c) results of GAG assay show no significant difference between labeled and unlabeled cells.

Silicon carbide (SiC) possesses excellent radiation tolerance, thus, SiC and its composites are promising materials for current and future nuclear systems [1]. However, the atomistic processes that underlie the irradiation response are not sufficiently understood, due largely to the limited spatial resolution of conventional analytical tools. Comparing aberration-corrected scanning transmission...

The Jarrah forest of southwestern Australia supports mineral and timber production and provides important food plants for three threatened black-cockatoo species. To assist the integration of conservation and production objectives, we studied the landscape distribution of two important black-cockatoo food sources, the eucalypts Jarrah Eucalyptus marginata and Marri Corymbia calophylla, at a min...

Plum bark necrosis-stem pitting (PBNSP) disease was first observed in 1986 affecting plum (Prunus salicina Lindl.) cv. Black Beaut trees in two orchards in Dinuba, CA (8). All of the Black Beaut plum trees had been whip-grafted with a single cultivar Wickson plum scion per tree to serve as a pollenizer, and all Wickson grafts failed. A year later, the same trees were grafted a second time with ...

Computations in the calculable small coupling regime of string theories and the general consensus that no new physics has to be invoked in continuing to the large coupling (black hole) regime, suggest the following picture. Quantum states are not black holes even if energy distributions would suggest so. Black holes appear as macrostates, i.e. with the same procedure that blures the quantum coh...

Intergroup relation perspectives stem from research in Western contexts with clear distinctions between the dominant and nondominant groups. In South Africa, with at least 13 different cultural groups and 11 official languages, no group is dominant in all life spheres. We examine the relationship between identity and in-/out-group orientation across Black-Zulu, Coloured (mixed racial ancestry),...

We examine factors contributing to the gender gap in employment in science, technology, engineering, and math (STEM) among men and women with bachelor’s degrees in computer science and engineering, the two largest and most male-dominated STEM fields. Data come from the National Science Foundation’s (NSF) Scientists and Engineers Statistical Data System (SESTAT) from 1995 to 2008. Different fact...

Microphthalmia-associated transcription factor (Mitf) is a key regulator for differentiation of melanoblasts, precursors to melanocytes. The mouse homozygous for the black-eyed white (Mitfmi-bw) allele is characterized by the white-coat color and deafness with black eyes due to the lack of melanocytes. The Mitfmi-bw allele carries LINE-1, a retrotransposable element, which results in the Mitf d...
