1. Curcumin is a naturally occurring poly-phenolic compound with a broad range of favourable biological functions, including anti-cancer, anti-oxidant and anti-inflammatory activities. The low bioavailability and in vivo stability of curcumin require the development of suitable carrier vehicles to deliver the molecule in a sustained manner at therapeutic levels. 2. In the present study, we investigated the feasibility and potential of poly(caprolactone) (PCL) nanofibres as a delivery vehicle for curcumin for wound healing applications. By optimizing the electrospinning parameters, bead-free curcumin-loaded PCL nanofibres were developed. 3. The fibres showed sustained release of curcumin for 72 h and could be made to deliver a dose much lower than the reported cytotoxic concentration while remaining bioactive. Human foreskin fibroblast cells (HFF-1) showed more than 70% viability on curcumin-loaded nanofibres. 4. The anti-oxidant activity of curcumin-loaded nanofibres was demonstrated using an oxygen radical absorbance capacity (ORAC) assay and by the ability of the fibres to maintain the viability of HFF-1 cells under conditions of oxidative stress. 5. The curcumin-loaded nanofibres also reduced inflammatory induction, as evidenced by low levels of interleukin-6 release from mouse monocyte-macrophages seeded onto the fibres following stimulation by Escherichia coli-derived lipopolysaccharide. 6. The in vivo wound healing capability of the curcumin loaded PCL nanofibres was demonstrated by an increased rate of wound closure in a streptozotocin-induced diabetic mice model. 7. These results demonstrate that the curcumin-loaded PCL nanofibre matrix is bioactive and has potential as a wound dressing with anti-oxidant and anti-inflammatory properties.

Introduction: Single-nucleotide polymorphisms (SNPs) represent a significant genetic variation influencing individual responses to cosmetic dermatology treatments. SNP profiling offers a pathway to personalized skincare by enabling practitioners to predict patient outcomes, customize interventions, and mitigate risks.
Background: The integration of genetic insights into dermatology has gained traction, with SNP analysis revealing predispositions in skin characteristics, such as collagen degradation, pigmentation, and inflammatory responses.

The present experimental study aimed to assess the wound healing and anti-inflammatory effects of green synthesized copper nanoparticles (CuNPs) by the methanol extract of (Boiss), as a plant with various pharmacological effects, such as anti-inflammatory and antimicrobial effects, in traditional and modern medicine. The precipitation approach was used for the green synthesis of CuNPs by mixing the methanol and copper sulfate solution. Cell viability and fibroblast proliferation assay were performed by MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) assay.

Background: The marine environment boasts distinctive physical, chemical, and biological characteristics. While numerous studies have delved into the microbial ecology and biological potential of the marine environment, exploration of genetically encoded, deep-sea sourced secondary metabolites remains scarce. This study endeavors to investigate marine bioproducts derived from deep-sea water samples at a depth of 1,000 m in the Java Trench, Indonesia, utilizing both culture-dependent and whole-genome sequencing methods.

Introduction: Alopecia is a systemic disease with multiple contributing factors. Effective treatment is challenging when only hair growth mechanisms are targeted while ignoring the role of maintaining hair follicle microenvironment homeostasis, which is crucial for cell growth and angiogenesis. Oxidative stress and inflammation are major disruptors of this microenvironment, leading to inhibited cell proliferation and compromised hair follicle circulation.

Background/objectives: Schizophrenia is a complex mental disorder influenced by genetic and environmental factors, including dietary habits. Oxidative stress and inflammation play a crucial role in the pathophysiology of schizophrenia. Emerging research suggests that diet may affect schizophrenia through different biological mechanisms beyond oxidative stress and inflammation.
