Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management

Advanced Science, EarlyView.
A programmable self‐heating microneedle patch enables on‐demand, timed‐sequence insulin delivery via user‐triggered quadrant activation. Each activation generates localized heat that melts a phase‐change barrier, accelerating drug release. In diabetic rats, sequential quadrant activation counteracts four meal‐mimicking glucose spikes over 24 h without ...

Characterization of double bond position in free fatty acids of human sebum

Journal of Chromatography Open
Free fatty acids (FFAs) are essential components of skin surface lipids (SSLs), which consist of a blend of epidermal and sebaceous lipids. The sebum component of SSLs is abundant in seborrheic body areas, which are rich in sebaceous glands (SGs).

Preparation of novel cosmetic white pigment by pyrophosphate treatment of zinc oxide

Cerâmica, 2021
Zinc oxide, which has photocatalytic activity, is used as a white pigment in cosmetics. With cosmetics containing zinc oxide, some sebum on the skin is broken down by the UV rays of the sun. In this study, in order to suppress the photocatalytic activity

Single‐Nucleus Transcriptomic Atlas of Human Vellus Hair Pilosebaceous Units Reveals Age‐Associated Remodeling

Advanced Science, EarlyView.
Human vellus pilosebaceous units (PSUs) remain uncharted. This single‐nucleus atlas reveals coordinated remodeling of the aging PSU niche: reduced bulge stem cell representation with altered regenerative programs, increased representation of a stress‐responsive channel+ epithelial state, enhanced androgen‐responsive sebaceous programs, reduced ...

A Comprehensive Review: The Bidirectional Role of Sebum in Skin Health

Bioengineering
Sebum plays a dual role in skin homeostasis, maintaining barrier function and providing antimicrobial defense. However, its dysregulation drives the pathophysiology of common skin diseases. This review explains that abnormal sebum secretion promotes acne

The production and composition of rat sebum is unaffected by 3 Gy gamma radiation [PDF]

International Journal of Radiation Biology, 2010
The aim of this work was to use metabolomics to evaluate sebum as a source of biomarkers for gamma-radiation exposure in the rat, and potentially in man. Proof of concept of radiation metabolomics was previously demonstrated in both mouse and rat urine, from the radiation dose- and time-dependent excretion of a set of urinary biomarkers.Rats were gamma-

The Needle‐Free Frontier: Redefining the Limits of Transdermal Insulin Delivery

Exploration, EarlyView.
Wei and colleagues reported a pH‐responsive, charge‐switchable polyzwitterionic polymer carrier that achieves non‐invasive transdermal insulin delivery without external energy input. The approach leverages adaptive compatibility with the cutaneous microenvironment to shuttle functional macromolecules across intact skin and achieve definitive systemic ...

A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

International Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.
