Fish and amphibians as test organisms for evaluation of effects caused by chemicals [PDF]

open access: yes, 2007
A large number of chemicals can contaminate aquatic environments and therefore be exposed to fish and amphibians during their sensitive stages of development.

New opportunities for bioscaffold‐enabled spinal cord injury repair

open access: yesBMEMat, EarlyView.
Schematic illustration of bioscaffolds for spinal cord injury repair. We summarize the effects of bioscaffold properties on SCI repair, highlight different types of bioscaffolds, various fabrication strategies, and in vivo transformations for the clinical development of SCI‐repairing bioscaffolds.

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

open access: yesBMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

Real‐time biosensing of Parkinson's disease biomarkers via NIR‐activated upconversion nanoparticles

open access: yesBMEMat, EarlyView.
Schematic illustration of the luminescence resonance energy transfer‐driven core‐shell‐shell UCNPs (cssUCNPs@Fluo4) nanoprobe for simultaneous monitoring of Ca²⁺‐temperature dynamics in Parkinson's disease models. Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with incompletely understood pathophysiology, necessitating ...

Why is an Egg Donor a Genetic Parent, but not a Mitochondrial Donor? [PDF]

open access: yes, 2019
What’s the basis for considering an egg donor a genetic parent but not a mitochondrial donor? I will argue that a closer look at the biological facts will not give us an answer to this question because the process by which one becomes a genetic parent, i.

Tetraspanin‐ESCRT sorting drives miR‐29b packaging into extracellular vesicles to reverse fibrosis in intrauterine adhesions

open access: yesBMEMat, EarlyView.
MiR‐29b is enriched in extracellular vesicles (EVs) via a tetraspanin transporter‐dependent endocytosis and sorting complex required for the endosomal transport (ESCRT)‐dependent pathway. These EVs target the 3′ untranslated region (3′UTR) of TGFB2, thereby inhibiting the TGF‐β/Smad3 signaling pathway and repairing endometrial damage in intrauterine ...

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

open access: yesBiological Reviews, EarlyView.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

Mitochondrial Replacement Techniques and Mexico’s Rule of Law: On the Legality of the First Maternal Spindle Transfer Case [PDF]

open access: yes, 2017
News about the first baby born after a mitochondrial replacement technique (MRT; specifically maternal spindle transfer) broke on September 27, 2016 and, in a matter of hours, went global.
