The morphological features of pluronic F127 at various concentrations were investigated and 20% aqueous pluronic F127 solution was chosen for the preparation of biomembrane. The pluronic solution was mixed with appropriate concentration of excipients such as PVA, Povidon S630, PG, Nipagin, Neomycin and Panthenol. The prepared pluronic F127 was thermosensitive, a liquid phase at low temperatures (≤10 °C) but converting into gel at temperatures above 20 °C, and formed stable biomembrane at 37 °C. The neomycin impregnated pluronic membrane suppressed the bacterial growth on agar plate by the sustained release of neomycin. The histological images of skin tissue after applying pluronic gel to burn injured area on rabbit confirmed that the pluronic F127 formulation functioned as a matrix to release drug as well as a biomembrane to protect burn injury. Thus, the formulated pluronic F127 may have a potential for the application of local treatment on burn injury.

Dry eye disease is a multifactorial condition characterized by a loss of homeostasis of the tear film. Among the various treatment approaches, the application of ophthalmic oil-in-water nanoemulsions with incorporated anti-inflammatory drugs represents one of the most advanced approaches. However, the liquid nature of nanoemulsions limits their retention time at the ocular surface.

Background: Surgical site infections (SSIs) have been shown to increase patient morbidity and mortality, impact on quality of life and place a significant economic burden on healthcare systems worldwide. Irrigation using wound cleansing and antiseptic effective solutions during surgical procedures is a key part of SSI prevention. The optimal solution would have minimal cytotoxicity to the patient while maintaining a minimum concentration required for antimicrobial activity necessary to prevent opportunistic pathogens and biofilm formation.

The high content of vitamin E, including tocopherols and tocotrienols (TCF-TTE), in palm oil () has made it a promising candidate for the alternative treatment of atopic dermatitis (AD). However, the limited solubility of TCF-TTE has restricted its therapeutic efficacy. In this study, pluronic-based micelles (MCs) encapsulating palm oil-derived TCF-TTE were formulated with dissolvable microarray patch-micelles (DMP-MC) using carboxymethyl cellulose (CMC) synthesized from empty fruit bunches of palm to optimize its delivery for AD.

Chronic pain is a prevalent condition affecting a significant portion of the global population and is known to be associated with an increased risk of cardiovascular diseases. Despite the clinical relevance, the mechanisms underlying the link between chronic pain and myocardial ischemia-reperfusion (MI/R) injury remain poorly understood. This study aimed to investigate the role of the superior cervical ganglion (SCG) in mediating the effects of chronic pain on MI/R injury and to develop a novel therapeutic strategy.
