Bezobjawowy podwójny łuk aorty u 87-letniego pacjenta

Reactive scattering calculations for (87)Rb+(87)RbHe→Rb2((3)Σ(u)(+),v)+He from ultralow to intermediate energies.

We investigate atom-diatom reactive collisions, as a preliminary step,in order to assess the possibility of forming Rb(2) molecules in their lowest triplet electronic state by cold collisions of rubidium atoms on the surface of helium nanodroplets [corrected]. A simple model related to the well-known Rosen treatment of linear triatomic molecules [N. Rosen, J. Chem. Phys. 1, 319 (1933)] in relat...

Tissue Factor in Microvesicles Shed From U 87 MG Human Glioblastoma Cells Induces Coagulation , Platelet Aggregation

Microvesicles (diameter ca 200 nm) from the cell-free supernatant of U87MG human glioblastoma cell caused platelet aggregation and coagulation in a manner identical with that previously shown for the intact cells. Both activities were inhibited by dansylarginine-N-(3-ethyl-1 .5pentanediyl) amide (DAPA). confirming the thrombindependent nature of both activities. The specific activities per micr...

Hypoxia up-regulates vascular endothelial growth factor in U-87 MG cells: involvement of TRPC1.

Canonical Transient Receptor Potential (TRPC) channels play important roles in diverse physiological processes. The contribution of TRPC channels to up-regulate VEGF expression under hypoxic conditions was studied in a malignant glioma cell line, U-87 MG cells. Up-regulation of VEGF gene expression by hypoxia was markedly suppressed by a TRPC channel blocker. RT-PCR showed that U-87 MG cells ex...

Epirubicin inhibits growth and alters the malignant phenotype of the U‑87 glioma cell line.

Epirubicin, an anthracycline derivative, is one of the main line treatments for brain tumors. The aim of the present study was to verify that epirubicin alters the growth and morphological characteristics of U‑87 glioma cells. In the present study, the effects of epirubicin were tested using cellular and biochemical assays, which demonstrated its anti‑proliferative and cytotoxic effects, with a...
