The tensegrity model hypothesizes that cytoskeleton-based microtubules (MTs) carry compression as they balance a portion of cell contractile stress. To test this hypothesis, we used traction force microscopy to measure traction at the interface of adhering human airway smooth muscle cells and a flexible polyacrylamide gel substrate. The prediction is that if MTs balance a portion of contractile...

Mesial temporal sclerosis (MTS) is the most common known pathologic substrate of epilepsy. Accurate preoperative identification of unilateral MTS bymagnetic resonance (MR) imaging has had a tremendous impact on the clinical management of medically refractory seizures. It was well known in the pre-MR era that obtaining a temporal lobectomy specimen that contained MTS conferred a higher probabili...

Multicellular tumor spheroids (MTS) have been exposed to chemotherapeutic agents in vitro (nitrogen mustard) or in vivo (cyclophosphamide) and analyzed in vitro in terms of altered growth patterns. Whether the MTS were exposed in vitro or in vivo, the major effect of the drugs was to induce a dose-dependent lag period before the normal MTS growth rate resumed. Exposure of MTS in the peritoneal ...

Sebaceous gland carcinomas (SGCs) are rare malignant skin tumors occurring sporadically or as a phenotypic feature of the Muir-Torre syndrome (MTS). A subset of patients with MTS have a variant of the hereditary nonpolyposis colorectal cancer syndrome caused by mutations in mismatch repair (MMR) genes, which lead to microsatellite instability (MSI). We evaluated the value of MSI and loss of exp...

The spindle of the colonial diatom Fragilaria contains two distinct sets of spindle microtubules (MTs): (a) MTs comprising the central spindle, which is composed of two half-spindles interdigitated to form a region of "overlap;" (b) MTs which radiate laterally from the poles. The central spindles from 28 cells are reconstructed by tracking each MT of the central spindle through consecutive seri...

Microtubule-associated protein 1A (MAP1A) and microtubule-associated protein 2 (MAP2) were shown to be colocalized on the same microtubules (MTs) within neuronal cytoskeletons by double-label immunoelectron microscopy. To investigate the electron microscopic disposition of MAP1A and MAP2 and their relationship to MTs in vivo, and to determine whether there are different subsets of MTs which spe...

Bundling of microtubules (MTs) is critical for the formation of complex MT arrays. In land plants, the interphase cortical MTs form bundles specifically following shallow-angle encounters between them. To investigate how cells select particular MT contact angles for bundling, we used an in vitro reconstitution approach consisting of dynamic MTs and the MT-cross-linking protein MAP65-1. We found...

Suspensions of multicellular mammary tumor spheroids (MTS) were allowed to interact with confluent monolayers of endothelial cells cultured on top of collagen gels. A number of early and late interactions between MTS and endothelial cell monolayers occurred. The early phase was characterized by the attachment of MTS to the culture and retraction of endothelial cells near the attached spheroid. ...

New and little-known terrestrial slugs are dealt with based on extensive collections made in East Africa (Kenya, Tanzania, and Uganda) 1993-2007. This account deals primarily with larger species from forests in the Eastern Arc Mountains of Tanzania. In Veronicellidae, Pseudoveronicella Germain, 1908 is extended to Tanzania by P. (Hoffmannia) zootoca tanzaniensis subsp. n. in the Udzungwa Mts. I...

OBJECTIVE To analyze the scientific production about the validity and reliability of the Manchester Triage System (MTS) protocol. METHOD A descriptive study of an integrative literature review. Articles on the validity and reliability of the MTS developed with children and adults published between 1999 and 2013 were included. RESULTS 14 articles were selected from a total of 8438, nine of v...
