The entanglement of very fine microfilaments provides extensive surface area and the micro-channels allow the fabric to be absorbent, breathable and capable of transporting perspiration away from the skin.
The performance of the new migration assay, as to the detection of toxicants, was initially tested with two positive controls: cytochalasin D (CytoD) interferes with actin microfilaments and taxol inhibits microtubule dynamics.
Vimentin is an intermediate filament protein expressed in Sertoli cells and important constituent of microfilaments and microtubules.
The 3D structure reinforces the uniformity of the microfilaments and increases ease of handling, making it possible to supply 3D microfilament wipes which are one-and-a-half to two times lighter than the lightweight wipes traditionally obtained using competing processes," he says.
These very fine microfilaments are irregular but spatially homogeneous, with electron-dense entities intermingled with axons.
The present findings extend previous observations by providing more direct evidence that DBP-induced germ cell aggregation results from dissolution of Sertoli-germ cell membrane cross-linking (via espin-APC), which in turn may result from the redistribution of microfilaments, such as vimentin and N-cadherin.
The resulting composites were extruded through a twin-screw microcompounder (DSM Xplore) at 230[degrees]C and 100 rpm to produce microfilaments of about 100 pm diameter.
The [beta]-catenin, specifically, binds to the cytoplasmatic portion of the E-cadherin and to the structure of actin microfilaments of the cytoskeleton as well, being involved in cell adhesion.
Intracellular connective structures are minute threads known as microtubules and microfilaments.
ACTB is one of the major components of cytoplasmic microfilaments in eukaryotic cells and plays an important role in diverse cellular functions, while GAPDH not only acts as a component of the glycolytic pathway but also takes part in other processes as well.
Drugs directed against the microfilaments have been too toxic to consider using because of the key role of microfilaments in muscle contraction, with muscle cells in the diaphragm and the heart being adversely affected.
Changes in microtubules and microfilaments due to a combined effect of ultrasound and cytostatics in HeLa cells.
