Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

FEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

A Nonlinear Panel Data Model of Cross-Sectional Dependence [PDF]

This paper proposes a nonlinear panel data model which can generate endogenously both `weak' and `strong' cross-sectional dependence. The model's distinguishing characteristic is that a given agent's behaviour is influenced by an aggregation of the views

Advanced glycation end products promote the release of endothelial cell‐derived mitocytosis

FEBS Open Bio, EarlyView.
Under diabetic conditions, AGEs induce mitochondrial damage in HUVECs, activating migrasome‐mediated mitocytosis. Migrasomes encapsulate damaged mitochondria and are released into the extracellular space, facilitating intercellular mitochondrial transfer.

Improving Transportability of Regression Calibration Under the Main/External Validation Study Design [PDF]

arXiv
In epidemiology, obtaining accurate individual exposure measurements can be costly and challenging. Thus, these measurements are often subject to error. Regression calibration with a validation study is widely employed as a study design and analysis method to correct for measurement error in the main study due to its broad applicability and simple ...

Improving Study Skills using Program Integrating Reflection Seminars [PDF]

arXiv, 2016
If students have a broad spectrum of study skills, learning will likely be positively affected, since they can adapt the way they learn in different situations. Such study skills can be learned in for example learning-to-learn courses. Several studies of such courses have been done over the years, but few of these have been carried out in longitudinal ...

An Economic Analysis of Voting in Sweden [PDF]

Using data from the Swedish Election Studies between 1985 and 1994 supplemented with time series on inflation and unemployment, I compare the impact of macro- and microeconomic variables on the individual vote. The principal finding is that microeconomic
