Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

The Astrophysical Journal, 1996 This paper explores the steady state behavior of mass-loaded winds. The topology of the critical point that results from the slowing of the wind is a function of the local slope of the mass-loading function. Mass-loading functions that increase sufficiently rapidly with radius as well as gravitational force can cause the steady state approximation to ...

Large Telescope Wind Loading [PDF]
International Astronomical Union Colloquium, 1984 One important large telescope design study area is the dynamic image degradation caused by wind forces upon various telescope structures and optical elements. The need to establish rapid thermal equilibration with the observatory environment further complicates the wind exposure problem.

Design and Testing of a Structural Monitoring System in an Almería-Type Tensioned Structure Greenhouse [PDF]
, 2020 Greenhouse cultivation has gained a special importance in recent years and become the basis of the economy in south-eastern Spain. The structures used are light and, due to weather events, often collapse completely or partially, which has generated ...

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Fatigue Load Estimation through a Simple Stochastic Model
Energies, 2014 We propose a procedure to estimate the fatigue loads on wind turbines, based on a recent framework used for reconstructing data series of stochastic properties measured at wind turbines. Through a standard fatigue analysis, we show that it is possible to

Natural environment analysis [PDF]
Qualitative analyses (and quantitatively to the extend possible) of the influence of terrain features on wind loading of the space shuttle while on the launch pad, or during early liftoff, are presented.

RIPK4 function interferes with melanoma cell adhesion and metastasis
Molecular Oncology, EarlyView.RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.
