- Maternal environmental health and cosmetics-associated exposures
Selected Articles
1. Membrane and co-culture engineering for high-level curcumin production in Escherichia coli.
The authors integrated chaperone-assisted folding, OMV-mediated secretion, and modular co-culture partitioning to relieve hydrophobic product burden and boost curcuminoid biosynthesis in E. coli. A 3 L fed-batch run reached 978 mg/L curcumin, the highest reported titer, demonstrating a scalable framework for hydrophobic natural products.
Impact: Establishes a versatile, high-titer microbial platform for producing a widely used cosmeceutical ingredient, enabling sustainable and quality-controlled supply chains.
Clinical Implications: While not a clinical study, the platform could improve availability and quality consistency of curcumin for dermatologic and cosmetic formulations, potentially reducing impurities and batch variability.
Key Findings
- Molecular chaperone co-expression improved solubility and catalytic activity of plant curcumin synthases.
- OMV-mediated secretion partially exported hydrophobic curcuminoids, alleviating intracellular accumulation and stress.
- Modular co-culture with carbon-source partitioning achieved 978 mg/L curcumin in a 3 L fed-batch, the highest reported titer.
Methodological Strengths
- Integrated multi-pronged engineering (chaperones, OMVs, modular co-culture)
- Validation in fed-batch bioreactor with record titer
Limitations
- Scale-up beyond 3 L and downstream purification/quality attributes were not detailed
- No economic analysis or assessment of regulatory compliance for cosmetic-grade production
Future Directions: Scale-up to pilot/GMP settings, define impurity profiles and stability for cosmetic-grade curcumin, and generalize the platform to other hydrophobic actives.
Curcuminoids, the major bioactive compounds of Curcuma longa, possess broad pharmacological activities including anticancer, antioxidant, and anti-inflammatory effects, making them valuable for pharmaceutical, nutraceutical, and cosmetic applications. Microbial biosynthesis provides a sustainable alternative. However, the efficiency remains limited due to the poor enzyme expression and the intrinsic hydrophobicity of curcuminoids, which causes intracellular accumulation and metabolic stress. Here, we develop a
2. Herbal medicine-derived carbon quantum dots in thermosensitive hydrogel: A multifunctional therapeutic strategy for UVB-induced photodamage.
MQEF-derived carbon quantum dots, embedded in a thermosensitive hydrogel, displayed biocompatibility and dual antimicrobial/restorative functions. In vitro and in vivo models showed mitigation of UVB-induced oxidative, inflammatory, apoptotic damage and inhibition of collagen degradation, improving epidermal architecture and collagen integrity.
Impact: Demonstrates a green, multifunctional topical platform that addresses multiple pathways of photodamage, offering a promising direction for cosmeceutical and dermatologic applications.
Clinical Implications: Suggests a candidate hydrogel dressing for UVB photodamage and photoaging with antimicrobial and restorative properties; human safety/efficacy trials are needed before clinical adoption.
Key Findings
- MQEF-derived CQDs exhibited superior antioxidant capacity and no significant toxicity in HaCaT cells.
- Incorporation into a thermosensitive hydrogel yielded dual antimicrobial and restorative functions compatible with skin physiology.
- In vitro and in vivo tests showed reduced UVB-induced oxidative stress, inflammation, apoptosis, and collagen degradation, restoring epidermal structure.
Methodological Strengths
- Convergent evidence from both in vitro (HaCaT) and in vivo models
- Physicochemical tuning (temperature, pH, rheology) to match skin environment
Limitations
- No human clinical data; translational effectiveness remains untested
- Long-term safety, dosing, and real-world photoprotection performance are not established
Future Directions: Conduct first-in-human safety and tolerability studies, evaluate efficacy in photoaging/photodermatoses, and perform regulatory toxicology and scalable manufacturing assessments.
Overexposure to ultraviolet B (UVB) radiation induces oxidative stress, inflammation, and apoptosis, which accelerates collagen degradation and skin aging. Current strategies for managing photodamage mainly focus on sun protection and skin repair; however, comprehensive therapeutic approaches are urgently needed. Herbal medicine-derived materials have shown great promise in combating photodamage. Modified Qing'e Formula (MQEF) has demonstrated the ability to treat photodamage by restoring redox ho
3. Ethno-cultural risk of ante-natal lead exposure among South Asian women in the UK.
In a Leeds cohort, ante-natal blood lead levels were significantly higher in South Asian versus Caucasian pregnant women. Among South Asian participants, higher BLLs were associated with living in pre-1970 housing, pesticide use in South Asia, purchasing fish from ethnic shops, and cosmetics shopping patterns, informing targeted prevention.
Impact: Identifies ethno-cultural and cosmetics-related determinants of lead exposure in pregnancy, enabling culturally tailored guidance for at-risk groups.
Clinical Implications: Supports focused risk assessment and counseling in antenatal care for South Asian women, including inquiry about traditional cosmetics and specific food sources; may inform screening and public health guidance.
Key Findings
- Ante-natal blood lead levels were significantly higher in South Asian (n=98) versus Caucasian (n=38) women in Leeds (t=4.00, df=134, p=0.0005).
- Among South Asian women, higher BLLs were associated with living in homes built before 1970 (t=2.558, p=0.012).
- Additional factors linked to raised BLLs included pesticide use in South Asia (t=2.880, p=0.005), purchasing fish from ethnic shops (t=3.494, p=0.001), and cosmetics shopping behaviors.
Methodological Strengths
- Direct BLL quantification using ICP-MS
- Comparative recruitment of South Asian and Caucasian women with environmental and ethno-cultural data
Limitations
- Single-city sample with modest size limits generalizability
- Observational design with potential residual confounding
Future Directions: Expand to multi-center cohorts, chemically characterize implicated cosmetics and foods, and evaluate links between maternal BLL and detailed birth/neurodevelopmental outcomes.
BACKGROUND: Maternal lead exposure, shaped by environmental and cultural factors, can transfer to the foetus. Culturally embedded practices among South Asian women, including dietary habits and traditional cosmetics, may increase exposure compared with Caucasian women. This study measured ante-natal blood lead levels in South Asian mothers in Leeds, UK, and examined associated environmental, ethno-cultural, lifestyle, and foetal outcome factors. METHODS: Pregnant SA and Caucasian women were recr
