Diabetic foot, leg ulcers and decubitus ulcers affect millions of individuals worldwide leading to poor quality of life, pain and in several cases to limb amputations. Despite the global dimension of this clinical problem, limited progress has been made in developing more efficacious wound dressings, the design of which currently focusses on wound protection and control of its exudate volume. The present in vitro study systematically analysed seven types of clinically-available wound dressings made of different biomaterial composition and engineering.

Developing human papillomavirus (HPV) therapeutic DNA vaccines requires an effective delivery system, such as cell-penetrating peptides (CPPs). In the current study, the multiepitope DNA constructs harboring the immunogenic and conserved epitopes of the L1, L2, and E7 proteins of HPV16/18 (pcDNA-L1-L2-E7 and pEGFP-L1-L2-E7) were delivered using KALA and REV CPPs with different properties in vitro and in vivo. Herein, after confirmation of the REV/DNA and KALA/DNA complexes, their stability was investigated against DNase I and serum protease.

With a rising incidence in an aging population, controversy surrounds surgical versus nonoperative treatments, particularly for displaced 3- and 4-part fractures in older patients. Locking plates (LP) and proximal intramedullary nails (PHN) are primary choices for surgical intervention, but both methods entail complications.

Liver cancer is a leading cause of cancer-related deaths worldwide, highlighting the need for innovative approaches to understand its complex biology and develop effective treatments. While traditional animal models have played a vital role in liver cancer research, ethical concerns and the demand for more human-relevant systems have driven the development of advanced models. Spheroids and organoids have emerged as powerful tools due to their ability to replicate tumor microenvironment and facilitate preclinical drug development.

Background: The German cockroach () is a pest with a global distribution that has adapted to live in human environments. threatens human health by producing asthma-inducing allergens, carrying pathogenic/antibiotic-resistant microbes, and contributing to unhealthy indoor environments. Effective application of insecticides can play an important role in cockroach control programs.
