Selected Articles
1. Flexible Microfluidic Devices for Tunable Formation of Double Emulsion.
The authors present a stretchable microfluidic device that tunes double-emulsion core size, shell thickness, and generation frequency without altering flow rates. Applying ~16% device strain increased core volume ~84% and shell volume ~23%, enabling real-time, on-site formulation control relevant to cosmetics, food, and bioapplications.
Impact: Provides a foundational, generalizable method for tunable double-emulsion generation, a core need for stable, controlled-release cosmetic formulations. The device adds real-time, on-site adjustability without redesigning chips or changing fluids.
Clinical Implications: While preclinical, this platform can accelerate development of cosmetic and dermatologic formulations with precise release kinetics and improved stability, potentially enabling personalized topical therapies.
Key Findings
- Flexible, stretchable microfluidic device tunes double-emulsion core size and shell thickness without changing flow rates.
- Approximately 16% device strain increased core volume by ~84% and shell volume by ~23%, while decreasing generation frequency.
- Demonstrated high-precision, reproducible, on-site real-time tunability across multiple stretching scenarios.
Methodological Strengths
- Quantitative demonstration of tunability with defined strain and measured changes in core/shell volumes.
- Generalizable approach not requiring device redesign or fluid property changes.
Limitations
- Proof-of-concept; industrial-scale throughput and long-term droplet stability not evaluated.
- Limited fluid chemistries tested; performance in complex cosmetic formulations remains to be shown.
Future Directions: Validate scalability, robustness with cosmetic-grade oils/surfactants/actives, and integrate in-line quality control for GMP manufacturing.
2. Mastectomy Alone or with Immediate Breast Reconstruction: Trend, Precipitating Factors, Patients Reported Outcome, and Oncologic Safety Analysis with and without Propensity Score Matching from 3759 Mastectomy Patients.
In a 3,759-patient retrospective cohort with propensity score matching, immediate breast reconstruction after mastectomy improved patient-reported cosmetic outcomes without increasing locoregional recurrence, distant metastasis, or overall mortality over a median 106.1 months. Younger age, preoperative MRI, luminal A subtype, nipple-sparing technique, and high-volume/oncoplastic surgeons were independently associated with reconstruction.
Impact: Provides high-quality observational evidence supporting oncologic safety of immediate reconstruction with better aesthetic outcomes, informing patient counseling and health system resource planning.
Clinical Implications: Supports offering immediate reconstruction to suitable candidates without compromising cancer control and highlights factors that may improve reconstruction access and outcomes.
Key Findings
- Among 3,759 mastectomy patients, 29% underwent immediate breast reconstruction; reconstruction rates increased over time while mastectomy alone decreased.
- Immediate reconstruction yielded better patient-reported cosmetic outcomes and outcomes comparable to breast-conserving surgery.
- After propensity score matching and median 106.1-month follow-up, no differences were observed in locoregional recurrence, distant metastasis, or overall survival versus mastectomy alone.
Methodological Strengths
- Large single-institution cohort with propensity score matching and long-term follow-up.
- Inclusion of multivariate analysis and patient-reported outcomes.
Limitations
- Retrospective, single-institution design may introduce selection and practice-pattern biases.
- Reconstruction techniques and complication profiles are not detailed in the abstract.
Future Directions: Multi-center prospective studies to validate oncologic safety across reconstruction types and assess quality-of-life, cost-effectiveness, and equitable access.
3. Zinc oxide nanoparticles promote migrasomes formation.
ZnO nanoparticles (28 nm) enhance migrasome biogenesis linked to elevated PI(4,5)P2 and GTP-RhoA, and support mitocytosis to mitigate CCCP-induced mitochondrial damage. These findings suggest nanoparticle-driven modulation of intercellular communication and organelle quality control with implications for cosmetic safety and environmental health.
Impact: Reveals a mechanistic link between widely used cosmetic nanoparticle ZnO and migrasome biology/mitochondrial quality control, informing safer-by-design strategies and regulatory risk assessment.
Clinical Implications: Guides safety assessment of ZnO-containing sunscreens and topical products by highlighting potential effects on intercellular vesicle signaling and mitochondrial homeostasis.
Key Findings
- 28 nm ZnO nanoparticles increase migrasome formation associated with elevated PI(4,5)P2 and GTP-RhoA.
- ZnO nanoparticles mitigate CCCP-induced mitochondrial damage via mitocytosis, preserving cellular integrity.
- ZnO-induced migrasomes contain mitochondria, lysosomes, lipid droplets, and ZnO nanoparticles.
Methodological Strengths
- Mechanistic readouts linking lipid signaling (PI(4,5)P2) and RhoA activity to migrasome biogenesis.
- Functional assessment showing mitigation of mitochondrial damage under CCCP stress.
Limitations
- In vitro study; lacks in vivo validation and dose–response relative to real-world exposure.
- Specific cell types and exposure conditions may limit generalizability to human tissues.
Future Directions: Define safe exposure windows in relevant skin models and in vivo; assess formulation-dependent effects and chronic exposure outcomes.
