    BACKGROUND: In epilepsy stigma, certain perceptions are culturally dependent and greatly influence a person's attitudes. Hence, we aimed to explore the perceptions associated with attitudes toward epilepsy in various urban subpopulations.

    METHOD: This is a mixed-method study employing the Public Attitude Toward Epilepsy (PATE) scale as the quantitative measure, followed by a semi-structured interview. The qualitative data were then counted and analyzed concurrently with the quantitative data.

    RESULT: A total of 410 respondents (104 people with epilepsy [PWE]; 104 family members [FM]; 100 medical students [MS]; 102 public [Pb]) aged 37 years (IQR 23-55) were recruited. They were mostly female (57.3%), Chinese (52.0%), and highly educated (63.7%). The attitudes toward epilepsy among medical students are the best, followed by the PWE and their family members, and the worst among the public. The qualitative results revealed 4 main themes, which were "general social values", "epilepsy severity and control", "PWE's abilities", and "harms and burdens to the respondents and others". A two-dimensional perception model was constructed based on these themes, which consisted of general-personal and universal-specific dimensions. Generally, the PWE/FM subgroup focused more on PWE's abilities, whereas the MS/Pb subgroup more on general social values, and harms and burden. In the education aspect, most attitudes were related to the epilepsy severity and PWE's abilities, whereas in employment, the main consideration was the PWE's abilities. Burden to life and concern about inheritance were major considerations in the marital relationship. Those with positive attitudes tend to highlight the importance of general social values, while negative attitudes associated more with epilepsy severity. In general domain, general social values were the main considering factor but in personal domain, most participants will consider epilepsy severity and control, harms and burden to themselves.

    CONCLUSION: The perceptions underlying attitudes toward epilepsy were complex and varied between subpopulations, attitude levels, domains, and aspects of life. (304 words).

    Environmental DNA (eDNA) metabarcoding is a valuable tool for assessing aquatic biodiversity, but the high cost and complexity of DNA extraction pose challenges for widespread adoption, especially in developing countries. This study presents a cost-effective eDNA extraction method using a guanidine hydrochloride (GuHCl) buffer, proteinase-K digestion, and isopropanol precipitation to improve the detection of fish communities. Comparison with the Qiagen DNeasy Blood & Tissue Kit using MiFish universal primers showed that the GuHCl protocol detected more fish species in freshwater samples, with comparable performance in relative read abundance metrics. However, the GuHCl method exhibited higher PCR inhibition in brackish samples, likely due to salinity and natural inhibitors. The results suggest that the GuHCl-based method is a viable alternative, offering enhanced sensitivity for low-abundance species in freshwater samples and cost savings. This protocol facilitates large-scale eDNA metabarcoding for ecological studies and conservation management efforts.•The GuHCl protocol identified a greater diversity of fish species in freshwater samples than the Qiagen kit, but detected fewer species in brackish water samples.•Both extraction methods demonstrated robust positive correlations in metrics of relative read abundance.

    Nanogels offer hope for precise drug delivery, while addressing drug delivery hurdles is vital for effective prostate cancer (PCa) management. We developed an injectable elastin nanogels (ENG) for efficient drug delivery system to overcome castration-resistant prostate cancer (CRPC) by delivering Decursin, a small molecule inhibitor that blocks Wnt/βcatenin pathways for PCa. The ENG exhibited favourable characteristics such as biocompatibility, flexibility, and low toxicity. In this study, size, shape, surface charge, chemical composition, thermal stability, and other properties of ENG were used to confirm the successful synthesis and incorporation of Decursin (DEC) into elastin nanogels (ENG) for prostate cancer therapy. In vitro studies demonstrated sustained release of DEC from the ENG over 120 h, with a pH-dependent release pattern. DU145 cell line induces moderate cytotoxicity of DEC-ENG indicates that nanomedicine has an impact on cell viability and helps strike a balance between therapeutics efficacy and safety while the EPR effect enables targeted drug delivery to prostate tumor sites compared to free DEC. Morphological analysis further supported the effectiveness of DEC-ENG in inducing cell death. Overall, these findings highlight the promising role of ENG-encapsulated decursin as a targeted drug delivery system for CRPC.
