1. A novel integrated strategy combining feature-based molecular networking, QSIIR modeling, and in silico toxicity prediction accelerates the screening of illegal additives in cosmetics: Quinolones as a case study.
This analytical workflow integrates FBMN, a QSIIR-MLR model, and in silico toxicity prediction to non-targetedly detect and prioritize illegal quinolone adulterants in cosmetics. It clustered 51 quinolones (14 novel) into 13 groups with 1 ppm LOD using only 17 seed standards and accurately predicted concentrations from structural descriptors.
Impact: Provides a scalable, reference-standard-sparing approach to uncover concealed and novel adulterants, directly strengthening cosmetic safety surveillance and regulatory enforcement.
Clinical Implications: Enhances public health by enabling earlier detection of harmful adulterants, informing recalls, and guiding toxicology follow-up; supports cosmetic dermatologists in identifying exposure sources in adverse reactions.
Key Findings
- FBMN clustered 51 quinolones, including 14 novel analogs, into 13 structural groups using 17 seed standards.
- Achieved a limit of detection of 1 ppm for quinolones in cosmetic contexts.
- Developed a QSIIR model (MLR with 7 structural descriptors) to accurately predict quinolone concentrations.
- Integrated in silico toxicity prediction to prioritize potentially hazardous adulterants.
Methodological Strengths
- Integrated multi-technique pipeline (FBMN + QSIIR-MLR + in silico toxicity) enabling non-targeted discovery and prioritization.
- Analytical sensitivity demonstrated with LOD of 1 ppm and structural clustering leveraging spectral similarity.
Limitations
- Validation reported for quinolones; generalizability to other prohibited classes requires demonstration.
- External, real-world surveillance datasets and inter-laboratory reproducibility were not detailed.
Future Directions: Expand to other adulterant classes, prospectively validate across laboratories and product matrices, and link analytical flags to clinical toxicovigilance outcomes.
2. Evaluation of Facial Artery Course Variations, Diameters, and Depth Using Doppler Ultrasonography: A Systematic Review and Meta-Analysis.
A PROSPERO-registered meta-analysis shows near-universal Doppler ultrasound visualization of the facial artery, quantifies its course relative to the nasolabial fold, and characterizes depth and diameter changes across facial levels. These data provide actionable vascular maps to minimize intravascular filler injections and ischemic complications.
Impact: Directly informs pre-procedural vascular mapping for aesthetic injections, translating anatomical heterogeneity into practical safety guidance.
Clinical Implications: Routine Doppler ultrasound mapping of the facial artery at key facial levels can guide cannula/needle selection and injection planes to reduce ischemia and necrosis risk.
Key Findings
- Pooled visualization rates of the facial artery by Doppler ultrasound were 100%, 99.9%, and 99.8% across three facial levels.
- Course variations relative to the nasolabial fold: medial (Type A) 46.2%, crossing medial-to-lateral (Type C) 22.5%, lateral (Type B) 12.0%.
- Depth increased from 6.27 mm (level 1) to 8.04 mm (level 3), while diameter decreased from 2.14 mm to 1.46 mm.
- Final branch prevalence: angular (71.8%), lateral nasal (27.9%), superior labial artery (5.7%).
Methodological Strengths
- PRISMA-2020 adherence and PROSPERO registration with focused Doppler US outcomes.
- Quantitative synthesis of visualization rates, course variants, depth, and diameter across studies.
Limitations
- Only 10 studies included; heterogeneity in ultrasound protocols and operator expertise likely.
- Findings are from normal adult populations; applicability to post-surgical or variant anatomies may differ.
Future Directions: Standardize pre-procedural ultrasound mapping protocols and evaluate prospective impact on filler complication rates across training levels and facial subregions.
3. Development of Dual-Functional Titanium Implant for Osseointegration and Antimicrobial Effects via Plasma Modification.
Low-temperature plasma modification with an HMDSZ film and a genipin-crosslinked thermosensitive hydrogel enabled spatially programmed release of chlorhexidine (collar) and BMP-2 (body). The construct showed no cytotoxicity, enhanced mineralization/osseointegration, and superior antibacterial performance versus controls in a swine model at 2 weeks.
Impact: Introduces a clinically relevant, dual-functional surface that addresses two leading implant failure modes—poor osseointegration and infection—using a scalable plasma process.
Clinical Implications: May reduce early failures and peri-implant infections, improving functional and aesthetic outcomes in implant dentistry; supports future clinical translation with programmable local drug delivery.
Key Findings
- Plasma-treated HMDSZ surface with thermosensitive hydrogel enabled localized immobilization of chlorhexidine (2 mm collar) and BMP-2 (6 mm body) with controlled release.
- In vitro, modified surfaces were non-cytotoxic and promoted osteoblast differentiation, mineralization, and antibacterial activity.
- In vivo swine experiments showed superior bone-to-implant contact and antibacterial efficacy versus untreated and commercial implants within 2 weeks.
Methodological Strengths
- Comprehensive surface characterization with both in vitro and in vivo validation.
- Spatially resolved, dual-agent delivery design aligning with clinical implant geometry.
Limitations
- Short-term (2-week) animal data; long-term performance and release kinetics not reported.
- No human clinical trial data to confirm translational efficacy and safety.
Future Directions: Long-term, multi-species and human trials assessing osseointegration, microbiome shifts, and clinical endpoints (e.g., peri-implantitis) with optimized dosing and release profiles.
