Selected Articles
1. Nanoparticle-based oral rinses for plaque control: A systematic review of efficacy and safety.
This PRISMA-style review of 38 records (including 10 RCTs) finds that nano-enabled mouthwashes—especially silver nanoparticle formulations—produce a modest pooled reduction in plaque index. Evidence certainty varied and synthesis was narrative due to heterogeneity, but safety and efficacy were evaluated using RoB-2 and GRADE.
Impact: It synthesizes the most recent clinical, preclinical, and patent evidence on nanoparticle mouthrinses, quantifying plaque reduction and framing safety through standardized bias and certainty tools.
Clinical Implications: Nano-enabled mouthrinses may serve as adjuncts or alternatives to conventional agents (e.g., chlorhexidine) for short-term plaque control. Standardized RCTs with longer follow-up and comprehensive safety endpoints are needed before routine adoption.
Key Findings
- Included 38 records: 10 RCTs, 15 in vitro/animal studies, and 13 patents on nano-enabled mouthwashes.
- Silver nanoparticles were most studied; other nanomaterials included ZnO, TiO2, calcium phosphate, and herbal nanoemulsions.
- Pooled analysis indicated a reduction in plaque index by 0.32 (95% CI 0.25–0.39), with narrative synthesis due to heterogeneity.
Methodological Strengths
- Comprehensive multi-database and patent search with dual independent data extraction.
- Risk of bias assessed using RoB-2 and evidence certainty rated with GRADE.
Limitations
- Substantial heterogeneity across formulations, dosing, and study designs necessitated narrative synthesis.
- Long-term safety, optimal dosing, and head-to-head comparisons with standard agents remain limited.
Future Directions: Conduct CONSORT-compliant, adequately powered RCTs with standardized nanoparticle concentrations, longer follow-up, mucosal/staining/toxicity endpoints, and comparisons versus chlorhexidine and essential oils.
2. Hairy roots as a biotechnological tool for medicinal plant secondary metabolites: A systematic review.
This PRISMA-guided review consolidates evidence that hairy root cultures reliably produce bioactive metabolites and that elicitors such as jasmonic acid, salicylic acid, and nanomaterials significantly boost yields. It highlights scale-up and regulatory bottlenecks and calls for integrating genetic engineering, bioprocess optimization, and regulatory science.
Impact: It provides an actionable map of species, elicitation strategies, and engineering levers to unlock industrial-scale production of bioactives for pharmaceuticals and cosmetics.
Clinical Implications: Indirect clinical impact through sustainable, controlled production of bioactives used in dermatology and cosmetic formulations; regulatory alignment will be key for translation.
Key Findings
- Hairy root cultures offer genetic stability, hormone-independent growth, and sustained high-yield production of secondary metabolites.
- Elicitors including jasmonic acid, salicylic acid, and nanomaterials significantly enhance metabolite accumulation; molecular tools optimize pathways.
- Industrial translation is limited by species-specific yield constraints, transformation inefficiencies, and fragmented regulatory frameworks.
Methodological Strengths
- PRISMA-guided systematic search across PubMed, Scopus, and Web of Science with explicit inclusion/exclusion criteria.
- Focused synthesis on elicitation strategies and scale-up challenges relevant to industrial application.
Limitations
- Heterogeneity in species, elicitors, and reporting precluded quantitative meta-analysis.
- Regulatory and techno-economic data remain sparse, limiting direct translational conclusions.
Future Directions: Adopt standardized reporting of titers and productivity, integrate multi-omics and CRISPR pathway engineering, and develop harmonized regulatory guidance and techno-economic analyses for scale-up.
3. An automated high-throughput platform reveals chromatic phototactic disruption in Daphnia magna exposed to the UV filters benzophenone-3 and octocrylene.
Using an automated multi-wavelength tracking platform, the study shows that octocrylene and benzophenone-3 disrupt color-dependent phototaxis and locomotion in Daphnia magna across 0.1–1000 μg/L. OC increased negative phototaxis and reduced movement at 10 μg/L, whereas BP-3 enhanced both at 100–1000 μg/L, shifting color preferences toward UV.
Impact: Introduces a scalable behavioral toxicology platform and uncovers wavelength-specific neurobehavioral disruption by common cosmetic UV filters, informing environmental risk assessment and formulation choices.
Clinical Implications: While not directly clinical, the findings support safer sunscreen formulation decisions and regulatory scrutiny of UV filters to mitigate ecological impacts linked to consumer cosmetic use.
Key Findings
- Control Daphnia preferred blue/white light; strongest negative phototaxis under UV-A and weakest under red; locomotion highest under white, lowest under red.
- Octocrylene at 10 μg/L increased negative phototaxis and reduced movement; benzophenone-3 at 100–1000 μg/L enhanced both phototaxis and locomotion.
- UV filters shifted color preference toward UV, blue over white, and green over blue, indicating altered visual perception.
Methodological Strengths
- Automated high-throughput video tracking with multi-wavelength LED stimuli and Python-based analysis.
- Two complementary experimental setups enabling vertical phototaxis and color preference assays across 0.1–1000 μg/L.
Limitations
- Single-species laboratory study; ecological generalizability and population-level outcomes remain to be tested.
- Short-term exposures under controlled lighting; mixture effects and chronic exposures were not assessed.
Future Directions: Extend to chronic, multi-stressor exposures across taxa; link behavioral endpoints to fitness and diel migration; elucidate photoreceptor-level mechanisms and integrate into regulatory ecotoxicology batteries.
