First Mining School in the Ottoman Empire and Mining Engineer Training

History Studies International Journal of History, 2015
Osmanlı Devleti'nde madenler hem halkın hem de askerî kurumların ihtiyaçlarını karşılamıştır. XİX. yüzyıla gelindiğinde Osmanlı madenleri çağın gereklerine göre işletilemediklerinden verimliliklerini kaybetmişlerdir. Osmanlı Devleti'nde bir maden mektebinin olmayışı ve bununla birlikte madenleri ıslah edebilme kabiliyetine sahip kalifiye elemanların ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
