PM2.5 Induce Endothelial‐Mesenchymal Transition and Cardiac Fibrosis via the NCOA4‐Mediated Ferritinophagy

Advanced Science, EarlyView.
This study primarily reveals that PM2.5‐derived Fe‐containing particles, particularly magnetite, are specifically enriched in the heart. Here, they interact with NCOA4 in endothelial cells, disrupt iron homeostasis by enhancing ferritinophagy, and subsequently trigger the process of EndMT through the NCOA4/KLF5 pathway.

Type 2 Diabetes‐Associated Phenylacetylglutamine Induces Deleterious Inflammation Cycle in Myeloid Cells through β2 Adrenergic Receptors and Impedes Wound Healing

Advanced Science, EarlyView.
The microbiota‐derived metabolite phenylacetylglutamine (PAGln) is elevated in type 2 diabetes and tightly associated with poor healing in both diabetic and non‐diabetic human patients. PAGln promotes mouse inflammation and impairs healing through a transmissible β2‐adrenergic receptor–mediated trained‐immunity loop.

The Doppler effect and similar triangles

Results in Physics, 2019
The Euclidean version of Doppler effect will be explained using the properties of similar triangles. These properties will serve to explain the relationship between frequencies of propagated wavefronts, number of wavefronts and the time of emitting and ...

What is Doppler ultrasound? [PDF]

, 2011
The term Doppler should be capitalized because it refers to Christian Johann Doppler, an Austrian physicist (1803–1853). He described a phenomenon whereby the frequency of sound changes when it is reflected off a moving object.

Magnetic field dependence of spin-lattice relaxation in the s$\pm$ state of Ba$_{0.67}$K$_{0.33}$Fe$_{2}$As$_{2}$

, 2012
The spatially averaged density of states, , of an unconventional d-wave superconductor is magnetic field dependent, proportional to $H^{1/2}$, owing to the Doppler shift of quasiparticle excitations in a background of vortex supercurrents[1,2].

Single‐Cell RNA Sequencing of Thyroid Tissues Reveals Pathogenesis of Graves' Disease

Advanced Science, EarlyView.
Using single‐cell RNA sequencing and TCR profiling, this study constructed an immune cell atlas in thyroid tissue of Graves’ disease (GD), revealing dominant IFN‐γ‐secreting CD4+ T cells, expanded Tph and CD11c+ B cells, and enriched T/NK cells. Notably, GD thyroid follicular cells (TFCs) activated γδ T cells, which recruited cDC1 cells, suggesting a ...
