Summary
January’s cosmetic-related research converged on exposure science, precision imaging, regenerative integration, and translational nanomedicine. Human exposure experiments showed that personal care products can amplify dermal uptake and predicted serum levels of environmental SVOCs, reshaping risk assessment and formulation strategy. Non-invasive multispectral optoacoustic tomography achieved histology-correlated tumor mapping for pigmented BCC, supporting more tissue-sparing surgery. Mechanistic work revealed fascia-driven vascularization that improves scaffold survival, while oral-supplement-triggered in situ nanoparticle assembly enabled tumor-targeted immune activation in preclinical models. Cross-disciplinary environmental analyses also reframed historical air pollution burdens with modern health implications.
Selected Articles
1. Zinc nanoparticles from oral supplements accumulate in renal tumours and stimulate antitumour immune responses.
Oral zinc gluconate self-assembles with plasma proteins to form ZnO nanoparticles in vivo that preferentially accumulate in papillary renal tumors and recruit dendritic and CD8+ T cells, enhancing antitumor immunity in preclinical models.
Impact: Introduces a low-barrier, in situ nanomedicine strategy for tumor-targeted immune activation that could broaden accessibility and accelerate translation.
Clinical Implications: Motivates translational studies to define dosing, biodistribution, safety, tumor specificity, and combinations with checkpoint inhibitors prior to human trials.
Key Findings
- Oral zinc forms ZnO nanoparticles in vivo via protein-assisted assembly.
- Nanoparticles preferentially accumulate in papillary renal tumors.
- Accumulation recruits dendritic cells and CD8+ T cells to enhance antitumor immunity.
2. Exposure experiments and machine learning revealed that personal care products can significantly increase transdermal exposure of SVOCs from the environment.
Volunteer experiments showed lotions, baby oil, sunscreen, and BB cream increased dermal adsorption of multiple SVOC classes by ~1.6–2.0×, with tocopherol-containing formulations amplifying uptake; ML models predicted post-use rises in serum PAHs and TCEP.
Impact: First human experimental evidence that cosmetic formulations materially alter environmental chemical uptake and predicted systemic burden, challenging current exposure assumptions.
Clinical Implications: Supports counseling vulnerable groups on ingredient-driven uptake and informs regulators to incorporate co-exposure/formulation effects into safety testing and labeling.
Key Findings
- Common PCPs increased dermal SVOC adsorption by ~1.63–2.03×.
- Tocopherol-containing formulations further amplified uptake (~2.59×).
- ML predicted increases in serum 2–3 ring PAHs and TCEP post-use.
3. Mobilization of subcutaneous fascia contributes to the vascularization and function of acellular adipose matrix via formation of vascular matrix complex.
Murine multi-tracing and perturbation studies show subcutaneous fascia migrates to implants, delivering fascia-embedded vessels and forming a vascular matrix complex essential for vascularization and implant survival; limiting fascia impairs regeneration and causes collapse.
Impact: Reveals fascia as an active driver of biomaterial integration, informing scaffold design and surgical protocols to improve volume retention and cosmetic outcomes.
Clinical Implications: Encourages preservation and recruitment of fascia in soft-tissue reconstruction and engineering of scaffolds that integrate with fascia to enhance vascularization and survival.
Key Findings
- Fascia migrates to encase AAM implants and delivers embedded vessels.
- A dynamic vascular matrix complex forms and remodels with vascularization.
- Restricting/removing fascia markedly impairs vascularization and leads to collapse.
4. A proof-of-concept study for precise mapping of pigmented basal cell carcinoma in asian skin using multispectral optoacoustic tomography imaging with level set segmentation.
In 30 pigmented BCC cases, MSOT with automated level-set segmentation produced 3D tumor metrics that correlated strongly with histology (r=0.84 width, r=0.81 depth), enabling quantitative preoperative planning.
Impact: Delivers non-invasive, high-resolution mapping validated against histology, with clear potential to reduce tissue sacrifice and improve cosmetic outcomes in dermatologic surgery.
Clinical Implications: Supports adopting MSOT-based planning to reduce Mohs stages or re-excisions, shorten operative time, and preserve cosmesis; warrants larger accuracy and implementation studies.
Key Findings
- Automated segmentation enabled precise 3D delineation of pigmented BCC.
- MSOT-derived width and depth correlated strongly with histology.
- Isotropic resolution (~80 μm) supports surgical planning.
5. Pan-European atmospheric lead pollution, enhanced blood lead levels, and cognitive decline from Roman-era mining and smelting.
By integrating Arctic ice-core geochemical archives, atmospheric transport modeling, and modern exposure–response epidemiology, the study infers Roman-era emissions elevated European air lead, increased blood-lead levels, and contributed to population-level cognitive decline.
Impact: Cross-disciplinary framework links paleoarchives to modern health effects, reframing long-term environmental burdens and informing present-day exposure policy and counseling.
Clinical Implications: Reinforces the need for primary prevention, remediation of legacy contamination, and vigilant exposure assessment in at-risk populations.
Key Findings
- Ice-core records show elevated atmospheric lead during the Roman era.
- Modeled background lead likely raised population blood-lead levels.
- Applying modern exposure–response links modeled blood-lead to cognitive decline.
