AI-guided protein engineering delivered a thermostable, highly active manganese superoxide dismutase with anti-inflammatory activity, opening avenues for skincare and biomedical applications. Two clinical systematic reviews inform patient-facing decisions: device-assisted circumcision appears to maintain or improve sexual quality of life, and non-suture wound closure methods provide comparable infection and cosmetic outcomes with faster closure times.

Research Themes
- AI-assisted protein engineering for dermatology and biomedicine
- Minimally invasive procedures and patient-reported outcomes
- Wound closure strategies optimizing cosmetic results and efficiency

1. Engineering a manganese superoxide dismutase with enhanced thermostability and activity via protein language Models: Toward antioxidant and anti-inflammatory applications in biomedicine and skincare.
Using integrated protein language models and iterative mutagenesis, the authors engineered a Mn-SOD variant (M4) with markedly improved thermostability and 2.2-fold higher catalytic activity, which also activated Nrf2/HO-1 and reduced pro-inflammatory cytokines in human keratinocytes and macrophage-like cells. This demonstrates an AI-enabled route to robust antioxidant enzymes for skincare and biomedical applications.
Impact: Combines AI-guided design with experimental validation to deliver a functionally superior antioxidant enzyme relevant to dermatology and cosmetic science.
Clinical Implications: Preclinical findings suggest potential incorporation of engineered SODs into topical formulations for oxidative stress reduction and inflammation control; translational studies are needed.
Key Findings
- Protein language model-guided mutations yielded M4 (T19H/L90M/Q122K/A183I) with ~70% residual activity after 1 h at 90°C (1.8× over wild type).
- Catalytic activity increased to 1567.6 U/mg (2.2× over wild type).
- M4 activated Nrf2/HO-1 and suppressed IL-6, TNF-α, and IL-1β in LPS-stimulated HaCaT and RAW264.7 cells.
- Structural analyses indicate enhanced hydrophobic packing and reduced flexibility underpin improved stability.
Methodological Strengths
- Integration of multiple protein language models (PSSM, ESM-1v, SaProt) with iterative mutagenesis
- Multimodal validation: enzymology, structural modeling/MD, and cellular functional assays
Limitations
- No in vivo efficacy or safety data
- Formulation stability and skin penetration not assessed
Future Directions: Evaluate topical formulation stability, dermal delivery, and in vivo efficacy/safety in relevant skin models and early-phase trials.
2. Impact of device-assisted circumcision on sexual quality of life in adult males: a systematic review.
Across eight studies involving 965 adults using devices such as PrePex, ShangRing, and Alisklamp, device-assisted circumcision generally maintained or improved sexual satisfaction and function with minimal adverse effects on erectile function. Some studies reported longer intercourse duration and higher satisfaction, though results were mixed for these endpoints.
Impact: Provides the first comprehensive synthesis focused on sexual quality-of-life outcomes after device-assisted circumcision, informing counseling and device selection.
Clinical Implications: Clinicians can reassure adult patients that device-assisted circumcision is unlikely to harm sexual function and may improve satisfaction; shared decision-making should consider individual priorities and device profiles.
Key Findings
- Eight studies (n=965) of adult device-assisted circumcision were synthesized (PrePex 336; ShangRing 297; Alisklamp 267; others 65).
- Sexual satisfaction and function were maintained or improved; erectile function showed minimal adverse effects with possible long-term improvement.
- Findings on intercourse duration and satisfaction were mixed across studies.
- Risk of bias assessed using Newcastle-Ottawa Scale and EPHPP tools.
Methodological Strengths
- PRISMA-guided systematic search across multiple databases
- Formal risk-of-bias assessment (Newcastle-Ottawa Scale, EPHPP)
Limitations
- Heterogeneity of study designs and outcomes; no meta-analysis
- Primarily observational studies with potential confounding
Future Directions: Prospective comparative studies and standardized patient-reported outcome measures are needed to refine device selection and counseling.
3. Suture Techniques for Traumatic Wound Closure in the Emergency Department: A Systematic Review of Cosmetic, Functional, and Infection-Related Outcomes.
Across three RCTs, wound tapes and tissue adhesives achieved comparable infection and dehiscence rates to sutures, with similar or improved cosmetic outcomes and significantly shorter closure times, especially for low-tension or facial lacerations. Evidence supports non-suture methods as safe, efficient alternatives in selected emergency settings.
Impact: Synthesizes RCT evidence on cosmetic and safety outcomes for common ED laceration care, guiding efficient, patient-centered practice.
Clinical Implications: For low-tension or facial lacerations, consider wound tapes or tissue adhesives to reduce procedure time without compromising infection risk or cosmetic outcomes.
Key Findings
- Three RCTs comparing tapes/adhesives vs sutures in ED lacerations met inclusion.
- Non-suture methods showed similar infection and dehiscence rates compared with sutures.
- Cosmetic outcomes were similar or better with non-suture methods, with significantly shorter closure times, particularly for low-tension/facial wounds.
- Two trials were rated low risk of bias; overall study quality satisfactory.
Methodological Strengths
- Focus on randomized controlled trials with explicit outcomes (infection, dehiscence, cosmetic ratings, time)
- Multi-database search including PubMed and Cochrane CENTRAL; risk of bias assessed
Limitations
- Only three RCTs with potential heterogeneity and limited sample sizes
- Lack of long-term scar assessments and subgroup analyses
Future Directions: Larger, standardized RCTs with long-term scar and patient-reported outcomes to refine indications and protocols.
