1. Intranasal blood-brain barrier bypass enables sequential mitochondria-targeted bioengineered nanolamellar system for ischemic stroke therapy.
The authors engineer a microglia–mitochondria hybrid membrane-coated black phosphorus nanosheet system loaded with PolyMet and FTY720 to sequentially restore neuronal mitochondrial function and modulate microglial polarization. Intranasal administration bypasses the BBB, markedly enhancing brain targeting after ischemia-reperfusion injury.
Impact: Introduces a dual-biomembrane, sequential targeting nanoplatform with an intranasal BBB-bypass strategy, potentially shifting CNS drug delivery paradigms. It provides a mechanistic approach to mitigate ischemia-reperfusion injury.
Clinical Implications: While preclinical, this platform could inform future intranasal therapies for stroke and other CNS disorders by improving mitochondrial delivery and glial modulation, warranting safety and efficacy testing.

Future Directions: Perform in vivo efficacy and safety studies with standardized endpoints, evaluate chronic dosing, and optimize scalable GMP-grade manufacturing and stability.
Mitochondrial damage constitutes the central pathological mechanism of cerebral ischemia-reperfusion (I/R) injury. Targeted delivery of antioxidants to mitochondria and the phenotype polarization of glial cells holds great promise for effective treatment. However, the blood-brain barrier (BBB) remains a major obstacle, causing insufficient drug accumulation in neuronal mitochondria. Here, we develop a bioengineered nanolamellar system (MM@BPPF) by coating microglia-mitochondria hybrid biomembrane onto black phosphorus nanosheets (BP NSs) loaded with polymetformin (PolyMet) and fingolimod hydrochloride (FTY720). Microglia membrane facilitates inflammation-directed targeting to the injured brain regions, while mitochondria membrane confers homotypic targeting to mitochondria. Meanwhile, BP NSs, PolyMet, and FTY720 act sequentially to restore mitochondrial function of neuronal cells and modulate microglial polarization. Intranasal administration enables MM@BPPF to bypass the BBB, substantially improving brain-targeting efficiency. This work not only offers an innovative sequential targeting strategy for mitigating I/R injury but also presents a potential paradigm for treating other central nervous system disorders.
2. The social perception of performance enhancement and body modification: A systematic review and meta-analysis on anabolic steroids, tattoos, and cosmetic surgery.
Synthesizing 34 experimental studies (N=9114), this meta-analysis shows mixed yet stigmatizing social evaluations of AAS users, tattooed individuals, and cosmetic surgery recipients. Cosmetic surgery targets are seen as more attractive and trustworthy but less competent; tattoos associate with perceived criminality and lower hireability; AAS users are judged higher in reactive aggression and neuroticism.
Impact: First comprehensive meta-analysis quantifying social perceptions across performance enhancement and body modification, informing stigma-aware clinical communication and policy.
Clinical Implications: Clinicians can anticipate biases toward cosmetic surgery and tattoos, integrate stigma-reduction strategies in counseling, and adjust occupational and preventive interventions accordingly.
Key Findings
- Meta-analysis of 34 experimental studies with 9,114 participants on AAS, tattoos, and cosmetic surgery
- Cosmetic surgery targets perceived as more attractive/trustworthy/healthy but less competent
- Tattooed targets perceived as lower SES, more criminal/offender-typical, lower hireability and competence
- AAS users perceived as higher in reactive aggression and neuroticism, lower sportspersonship and agreeableness
Methodological Strengths
- Systematic synthesis across three domains with standardized effect sizes
- Large combined sample (N=9114) enabling precise estimates
Limitations
- Heterogeneity across studies and potential cultural/contextual biases
- Reliance on experimental vignettes may limit ecological validity
Future Directions: Assess moderators (culture, gender, exposure), include longitudinal and field studies, and test interventions to mitigate stigma in healthcare and workplace settings.
To our knowledge, few studies have attempted to explore the social perception of targets engaged in performance enhancement and body modification, and none has done so through a systematic review and meta-analysis. We conducted a meta-analysis on the social perception of anabolic-androgenic steroids (AAS), tattoo, and cosmetic surgery targets. Eligible experimental studies were identified through electronic database and ad hoc searches up to July 2025. We estimated effect sizes, in terms of the standardized mean difference, for the social perception ratings of the targets involved in the abovementioned practices on demographic, health, and psychosocial factors. Results from 34 studies with 9114 participants on AAS, tattoo, and cosmetic surgery were analyzed. Regarding performance enhancement, observers perceived the AAS (vs. no-AAS) target as less likely to display instrumental aggression, but having higher reactive aggression, lower sportspersonship, higher neuroticism, and lower agreeableness. Regarding body modification, the tattoo (vs. no-tattoo) target was perceived as more artistic, yet of a lower socioeconomic status, more offender typical and reoffend likely, and having lower hireability and competence. Furthermore, the cosmetic surgery (vs. no-cosmetic surgery) target was perceived as more attractive, approachable, trustworthy, and healthier, but also as less competent. Overall, observers show mixed perception of performance enhancement and body modification targets. The strong negative perceptions on competence, criminality, personality, and sportspersonship-especially considering the enhancement and modification overlap-highlight the extent of stigmatizing evaluation associated with these practices behaviours. Preventive, therapeutic, and occupational interventions may benefit from adjusting for the identified social perceptions.

Sudan dyes are carcinogenic colorants illicitly added to foods and cosmetics, posing serious health risks. Herein, a rapid dual-emission fluorescent probe based on two-dimensional (2D) ZnS nanosheets is developed for sensitive detection of Sudan dyes (III/IV). Compared with conventional nanoparticles, the nanosheet structure offers high surface accessibility, excellent dispersion, and reduced aggregation, enabling reliable sensing in complex matrices. The ZnS nanosheets (NS), synthesized via the solvothermal method, exhibit stable fluorescence emissions at 521 and 557 nm with photobleaching resistance. Fluorescence quenching by Sudan dyes is governed by the inner filter effect, allowing a rapid response within 20 s over a broad pH range (2-10). The probe shows high selectivity and reproducibility, with detection limits of 339/436 nmol L
