CD9- and CD81-positive extracellular vesicles provide a marker to monitor glioblastoma cell response to photon-based and proton-based radiotherapy.

Glioblastoma multiforme (GBM) is the most aggressive tumor of the central nervous system with a poor prognosis. In the treatment of GBM tumors, radiotherapy plays a major role. Typically, GBM tumors cannot be cured by irradiation because of intrinsic resistance machanisms.

Designing 3D Membrane Modules for Gas Separation Based on Hollow Fibers from Poly(4-methyl-1-pentene).

Designing hollow fiber (HF) membrane modules occupies one of the key positions in the development of efficient membrane processes for various purposes. In developing HF membrane modules, it is very important to have a uniform HF distribution and flow mixing in the shell side to significantly improve mass transfer and efficiency. This work suggests the application of different textile 3D HF structures (braided hoses and woven tape fabrics).

Activation of anti-oxidant Keap1/Nrf2 pathway modulates efficacy of dihydroartemisinin-based monotherapy and combinatory therapy with ionizing radiation.

The efficacy of radiotherapy depends not only on DNA damage but also on ROS production, both induced by ionizing radiation. Massive ROS production can induce cell death or activate protective pathways such as Keap1/Nrf2 pathway, which regulates intracellular cysteine availability through upregulation of SLC7A11, a subunit of xCT transporter, and subsequently glutathione synthesis, thus improving antioxidative defense. The anti-malaria drug dihydroartemisinin (DHA) shows anti-neoplastic potential.
