Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Patterning Skin Pigmentation via Dickkopf [PDF]

Journal of Investigative Dermatology, 2007
One of the striking regional variations in skin is its pigmentation. Yamaguchi et al. further dissect the mechanism of regional pigmentation by assessing the effects of dickkopf 1 (DKK1), an antagonist of the Wnt pathway produced in lightly pigmented skin, on melanocyte gene expression. The results provide a plethora of candidate genes that may mediate

Non‐Targeting shRNA‐Encoded Plasmid DNA Enhances Protective Immunity Through RIDD‐RIG‐I Signaling Pathway in the Zika Virus Animal Model

Advanced Science, EarlyView.
We present a novel DNA vaccine platform featuring intrinsic, non‐targeting dsRNA that significantly enhances immune responses by activating the regulated IRE1‐dependent decay‐RIG‐I signaling pathway. This research elucidates a previously uncharacterized mechanism for dsRNA‐mediated innate immune activation.

The performance of 11 fingertip pulse oximeters during hypoxemia in healthy human participants with varied, quantified skin pigmentResearch in context

EBioMedicine
Summary: Background: Fingertip pulse oximeters are widely available, inexpensive, and commonly used to make clinical decisions in many settings. Device performance is largely unregulated and poorly characterised, especially in people with dark skin ...

Thyroid hormone regulates distinct paths to maturation in pigment cell lineages [PDF]

, 2019
Thyroid hormone (TH) regulates diverse developmental events and can drive disparate cellular outcomes. In zebrafish, TH has opposite effects on neural crest derived pigment cells of the adult stripe pattern, limiting melanophore population expansion, yet

Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

Advanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...

Exploring the Vasculitis‐Tumors Link: Epidemiological Patterns, Mechanistic Insights, and Clinical Implications

Advanced Science, EarlyView.
This review outlines association between vasculitis and malignancies and provides practical value for clinicians in distinguishing primary vasculitis from malignancy‐associated forms and optimizing patient surveillance, improving recognition of tumor‐associated vasculitis to reduce the risk of misdiagnosis, supporting more accurate clinical decision ...

Comment on: The Vitamin D⁻Folate Hypothesis as an Evolutionary Model for Skin Pigmentation: An Update and Integration of Current Ideas, Nutrients 2018, 10, 554. [PDF]

, 2018
In response to a recent article by Jones et al. (Nutrients 10: 554⁻568, 2018) [1], we agree that three distinctive features evolved in Homo erectus prior to the emergence of modern humans.[...]
