Earthworms have a complex digestive system consisting of the mouth, pharynx, esophagus, crop, gizzard, and intestine which work together to pass the soil out. The gut soil and associated microbial load in earthworms' gut hinder the outcome of many experiments like in-vitro regeneration, histology, immunohistochemistry, molecular expression and toxicological studies. Currently, the available gut cleaning techniques are time-consuming and costly. The tissue paper method takes 4-7 days; the agar-agar method takes around 3-5 days to clean the gut. Therefore, refined techniques are needed to reduce the gut cleaning process in a cost-effective and at the same time in a minimum number of days. Bisacodyl is a medication used to treat constipation and it acts as a laxative drug that increases peristatic movement of the gut. It can also be used to cleanse the intestines before a bowel examination or surgery. The present study aims to enhance the gut-cleaning process in earthworm, Eudrilus eugeniae , using the drug bisacodyl. Briefly, the earthworm is exposed to different concentrations (1 mg, 2 mg, 4 mg, 6 mg, 8 mg and 10 mg) of bisacodyl and analyzed for its excretion rate. We observed that 4 mg is more efficient and aids in cleaning the earthworm's gut within two days. A lower bisacodyl concentration is inefficient in cleaning the gut in a shorter duration while at higher bisacodyl concentrations, worm experienced autotomy. Since the drug was active for only 45 mins, the worm became normal one hour after withdrawal from the experiment. Other than E. eugeniae , for Perionyx excavatus we observed 4 mg bisacodyl drug is efficient and aids in cleaning its gut within two days. Overall, the designed protocol is efficient for gut cleaning in a shorter duration in a cost-effective manner. [ABSTRACT FROM AUTHOR]

Background: Wound healing relies on a controlled inflammatory process vital for tissue regeneration. Chronic wounds, characterized by persistent inflammation and high infection risk, pose significant challenges in healthcare. Hydrogel dressings offer promise in wound care; however, the understanding of their role in managing inflammation and infection remains unclear. This study aimed to elucidate these processes and assess the efficacy of Asiatic acid (AA)-infused hydrogels in reducing inflammation and preventing infection. The unique properties of AA suggest its potential to modulate inflammation, promote tissue regeneration, and inhibit microbial colonization, thereby paving the way for specialized dressings that optimize healing outcomes., Methods: The investigation encompassed the antibacterial, anti-biofilm, antioxidant activity, and biocompatibility of AA using a fibroblast cell line. A hydrogel incorporating AA was developed and characterized through scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), contact angle analysis, tensile testing, swelling capacity, and thermal stability assessments. Biodegradability was evaluated via enzymatic degradation, alongside controlled drug release and antibacterial efficacy against MRSA. In vivo studies using a zebrafish model examined wound healing and immune response., Results: Results confirmed AA's potent antibacterial activity against MRSA and its effectiveness in disrupting mature biofilms. Additionally, AA exhibited strong antioxidant activity and biocompatibility. Morphological analysis revealed a pore structure conducive to wound healing, and the hydrogel demonstrated enhanced tensile strength, swelling properties, and thermal stability. In vivo, the AA-infused hydrogel accelerated wound closure, re-epithelialization, and immune response, supporting its potential for advanced wound care applications. In conclusion, the AA-infused chitosan hydrogel emerges as a promising candidate for advanced wound care therapies., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

The study by P. D. Yuan et al. titled "Adalimumab Dose Reduction and Withdrawal in Stable Non-Infectious Pediatric Uveitis: An Open-Label, Prospective, Pilot Study" examines dose reduction and withdrawal strategies in managing pediatric uveitis with adalimumab (ADA). The study aims to optimize treatment protocols by minimizing drug exposure while maintaining disease control. However, the open-label design introduces potential bias, and the absence of a control group limits the ability to draw definitive conclusions. The small sample size and short follow-up period further constrain the study's robustness. Methodological refinements, including a randomized controlled trial design with a larger sample size, extended follow-up, detailed adverse event data, standardized tapering protocols, and incorporation of objective outcome measures, are recommended to enhance the reliability and generalizability of the findings. These improvements could significantly inform clinical practice and contribute to the evidence base for pediatric uveitis management.
