In contrast, during metaphase and anaphase, microtubules are the dominant fibrous element of the spindle. The microtubules interact with chromosomes during these phases by joining to true kinetochores. Neither treatment with cytochalasin B or fixation with a low concentration of osmium tetroxide affects ...
If being integrated into pre-existing islets would be a key element for ADIP cells to be functional, then near-total ablation of β-cells with high dose streptozotocin (STZ) would most likely undermine the ability of ADIP cells to infiltrate the islets and restore normoglycemia. Therefore, to...
Samples were pelleted and washed in 0.2 M sodium cacodylate buffer, resuspended in 2% osmium tetroxide for 2 h at room temperature, and embedded in EPON resin following a standard schedule. After overnight incubation at 65 °C, specimens were sectioned to 80 nm, using a Leica UC...
The samples were sectioned into small pieces, 4–6 mm in length, post-fixed in 1% osmium tetroxide for 1 h, dehydrated in an ascending series of acetone and embedded in Durcopan resin (Fluka AG, Buchs, Switzerland) (Sheehan and Hrapchak, 1980). The polymerized resin was cut serially ...
Peptidoglycan (PG) is the major cell-wall structural element, as it forms a closed meshwork (sacculus) that provides a mechanical scaffold to support turgor pressure1,2. PG comprises of linear glycan strands, made up of N-acetylglucosaminyl-N-acetylmuraminyl disaccharides repeats that are cross...
An additional α-type PSM, PSMmec, is encoded on the mobile genetic element SCCmec type II and III of some methicillin-resistant S. aureus (MRSA) strains (10). Interestingly, PSMα1-4 and δ-toxin are abundant on the S. aureus cell surface (11). This feature demonstrates that PSMs ...
The most conspicuous and central element of the CNS is the almost spherical complex of fused left and right cerebral and pleural ganglia (the cerebropleural ganglion, cpg; diameter about 55 μm). Histologically, it is distinctly divided into cortex and fibrous medulla (see Figure3C). The cerebr...
(Re), osmium (Os), iridium (Ir), platinum (Pt), gold (Au), mercury (Hg) and a combination thereof, and X is a chalcogen element selected from the group consisting of sulfur (S), selenium (Se), tellurium (Te), oxygen (O) and a combination thereof, wherein the intercalation ...
A magneto-optical recording element comprises (A) an optically transparent dimensionally stable substrate and (B) a thermally alterable recording layer which contains an amorphous lantha
