Selected Articles
1. Madecassoside-functionalized platinum-based liposomes for sensitive skin: Enhancing rapid soothing and barrier homeostasis.
Pt–madecassoside complexes encapsulated in liposomes enhanced anti-inflammatory and neurogenic-soothing effects versus Pt-PVP liposomes, targeting TNF-α, IL-1β, and IL-17 and supporting barrier homeostasis. AI docking suggested strong binding to TRPV1/TRPA1/NK1R/H1R/ETAR, indicating a multi-target topical strategy for sensitive skin.
Impact: Introduces a novel, multi-receptor-targeted liposomal platform that could redefine soothing strategies for sensitive skin by combining bioactive functionalization with optimized delivery.
Clinical Implications: Provides a rationale for developing targeted, multi-pathway topical therapies for sensitive skin; supports formulation choices prioritizing liposomal delivery with bioactive surface functionalization. In vivo safety, skin penetration, and clinical efficacy studies are needed.
Key Findings
- Pt-MAD liposomes reduced inflammation, itch, and redness more effectively than Pt-PVP liposomes in vitro.
- MAD functionalization modulated TNF-α, IL-1β, and IL-17 and supported epidermal barrier homeostasis.
- AI docking indicated strong binding of Pt-MAD to TRPV1, TRPA1, NK1R, H1R, and ETAR.
- Liposomal encapsulation improved dispersion stability and transdermal delivery.
Methodological Strengths
- Head-to-head comparison with conventional Pt-PVP liposomes across multiple biological readouts.
- Mechanistic insights supported by AI-driven receptor docking analyses.
Limitations
- Evidence is limited to in vitro assays; no in vivo or clinical data.
- Docking predictions lack experimental validation of target engagement in skin.
Future Directions: Evaluate skin penetration, local and systemic safety, and efficacy in animal models, followed by randomized controlled clinical trials in sensitive skin populations.
2. Cosmetic and Quality of Life Outcomes of Supraclavicular vs Conventional Thyroidectomy Incisions in Unilateral Papillary Thyroid Carcinoma.
In a prospective nonrandomized cohort of 197 unilateral PTC patients, supraclavicular lateral incisions yielded higher scar satisfaction (median 9 vs 6) and better psychological well-being with comparable operative metrics and complications versus conventional median incisions. No recurrences occurred over a median 28-month follow-up.
Impact: Provides pragmatic evidence that a cosmetically favorable incision improves patient-reported outcomes without compromising safety, informing surgical approach selection in unilateral PTC lobectomy.
Clinical Implications: For suitable unilateral PTC patients, the supraclavicular incision can be offered to optimize scar satisfaction and psychological QoL with similar perioperative risk; surgeons should counsel patients on trade-offs and ensure appropriate training.
Key Findings
- Operative time, blood loss, and complication rates were comparable between supraclavicular and conventional incisions.
- Scar satisfaction was higher with the supraclavicular approach (median 9 vs 6; P=0.001).
- Psychological well-being improved significantly (P=0.036) with a trend toward better social well-being (P=0.066).
- No recurrences were observed over a median follow-up of 28 months.
Methodological Strengths
- Prospective comparative design with balanced group sizes and validated thyroid-specific QoL instruments.
- Objective scar assessment using visual analog scales and standardized follow-up.
Limitations
- Nonrandomized allocation introduces potential selection bias.
- Single-surgeon or single-center effects and limited long-term oncologic follow-up beyond 28 months.
Future Directions: Randomized trials or multicenter registries comparing incision approaches with longer oncologic follow-up and broader patient-reported outcomes (e.g., body image, neck function).
3. OSA-modification rice, debranched, and soluble starches encapsulating ferulic acid: interfacial effects and enhanced solubility, stability, bioactivity, and sustained release.
OSA-modified debranched starch (OSA-DBS) provided the highest ferulic acid encapsulation efficiency, improving solubility, stability, antioxidant and antibacterial activity, and yielding slow first-order release in vitro. Encapsulation relied on hydrogen bonding, van der Waals, and hydrophobic interactions, highlighting interfacial control as a formulation lever.
Impact: Addresses a long-standing formulation barrier for ferulic acid—instability and poor solubility—by identifying an optimal starch carrier (OSA-DBS) and mechanistic basis for improved performance relevant to cosmetics and dermal delivery.
Clinical Implications: Guides formulation scientists toward OSA-DBS carriers for more stable and bioactive ferulic acid in cosmetic and dermatologic products; requires validation of skin permeation, irritation, and real-time stability in finished formulations.
Key Findings
- Encapsulation mechanisms included hydrogen bonding, van der Waals forces, and hydrophobic interactions.
- OSA-DBS achieved the highest encapsulation efficiency due to compact cavity spiral structures.
- FA@OSA-DBS showed the strongest antioxidant and antibacterial activities with improved solubility and stability.
- In vitro release from FA@OSA-DBS was slow and followed a first-order kinetic model.
Methodological Strengths
- Direct head-to-head comparison of three OSA-modified starch carriers (RS, DBS, SS).
- Integrated evaluation of encapsulation, bioactivity, stability, and release kinetics.
Limitations
- Evidence limited to in vitro assays; no in vivo dermal delivery or human data.
- Long-term stability under cosmetic formulation conditions and skin compatibility were not assessed.
Future Directions: Assess dermal penetration, irritation/sensitization, photostability, and performance in finished cosmetic formulations; benchmark against other carriers (e.g., cyclodextrins, liposomes).
