Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Case Report: Suspected intestinal perforation caused by accidental ingestion of magnet

open access: yesFrontiers in Surgery
IntroductionChildren frequently swallow foreign objects, and ingesting magnets on occasion can cause major problems because they are composed of unique materials that draw to one another in the intestinal wall.

Magnetization transfer in magnetic resonance fingerprinting

open access: yesMagnetic Resonance in Medicine, 2019
PurposeTo study the effects of magnetization transfer (MT, in which a semi‐solid spin pool interacts with the free pool), in the context of magnetic resonance fingerprinting (MRF).MethodsSimulations and phantom experiments were performed to study the impact of MT on the MRF signal and its potential influence on T1 and T2 estimation.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Stellarator fusion systems enabled by arrays of planar coils

open access: yesNuclear Fusion
We present an overview of a novel electromagnetic coil configuration for stellarators and its application to two near-term fusion systems. The novel coil configuration is the planar coil stellarator, able to implement precisely-quasisymmetric 3D magnetic

INFORMED CONSENT IN SCHOOL-BASED ETHNOGRAPHY: USING VISUAL MAGNETS TO EXPLORE PARTICIPATION, POWER AND RESEARCH RELATIONSHIPS

open access: yesInternational Journal of Child, Youth & Family Studies, 2014
 This paper contributes to current ethical and methodological debates on informed consent in research with children and young people. It draws on ethnographic fieldwork conducted with young children (aged 5 to 7) and specifically on the use of photo ...

Research on Magnetism and Magnetization Intensity of Magnetic Fluid

open access: yesJournal of Physics: Conference Series, 2020
Abstract Magnetic fluid is a liquid magnetic material with high magnetization, fluidity and superparamagnetism. The composition and the performance of magnetic fluid in magnetic field were introduced. Magnetic model of magnetic fluid for application was established.

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

open access: yesFEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
