Magnetic beads and superparamagnetic (SP) colloid particles have successfully been employed for micromechanical manipulation of soft material, in situ probing of elastic properties, and design of smart materials (ferrogels). Here we derive analytical expressions for the equilibrium shape of...

Use of levamisole-adulterated cocaine is associated with increased load of white matter lesions.

BACKGROUND: Cocaine use has been associated with vascular pathologies, including cerebral white matter hyperintensities. Street cocaine is most often adulterated with levamisole, an anthelminthic drug that may also be associated with vascular toxicity. However, whether levamisole exposure from cocaine...

Matrix Biol. 2021 Jun;100:9-22. doi: 10.1016/j.matbio.2020.11.003. Epub 2020 Nov 28.

Degradation of dysfunctional, damaged, or misfolded proteins is a crucial component of the protein quality control network to maintain cellular proteostasis. Dysfunction in proteostasis regulation due to imbalances in protein synthesis, folding, and degradation challenges the integrity of the...

Comparison of Preoperative Cone-Beam Computed Tomography and 3D-Double Echo Steady-State MRI in Third Molar Surgery.

PMID: 34682896
J Clin Med. 2021 Oct 18;10(20). doi: 10.3390/jcm10204768.

We investigated the reliability of assessing a positional relationship between the inferior alveolar nerve (IAN) and mandibular third molar (MTM) based on CBCT, 3D-DESS MRI, and CBCT/MRI image fusion. Furthermore, we evaluated qualitative parameters such as inflammatory processes and...

Oxid Med Cell Longev. 2021 Oct 14;2021:6924251. doi: 10.1155/2021/6924251. eCollection 2021.

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease in humans and remains to have a fatal prognosis. Recent studies in animal models and human ALS patients indicate that increased reactive oxygen species (ROS) play an important...

Conservation of magnetite biomineralization genes in all domains of life and implications for magnetic sensing.

Proceedings of the National Academy of Sciences of the United States of America

Bellinger MR, Wei J, Hartmann U, Cadiou H, Winklhofer M, Banks MA.
PMID: 35012979
Proc Natl Acad Sci U S A. 2022 Jan 18;119(3). doi: 10.1073/pnas.2108655119.

Animals use geomagnetic fields for navigational cues, yet the sensory mechanism underlying magnetic perception remains poorly understood. One idea is that geomagnetic fields are physically transduced by magnetite crystals contained inside specialized receptor cells, but evidence for intracellular, biogenic...

The light-dependent magnetic compass sense of night-migratory songbirds can be disrupted by weak radiofrequency fields. This finding supports a quantum mechanical, radical-pair-based mechanism of magnetoreception as observed for isolated cryptochrome 4, a protein found in birds' retinas. The exact...
