Neurodegenerative diseases are significant health concerns that have a profound impact on the quality and duration of life for millions of individuals. These diseases are characterized by pathological changes in various brain regions, specific genetic mutations associated with the disease, deposits of abnormal proteins, and the degeneration of neurological cells. As neurodegenerative disorders vary in their epidemiological characteristics and vulnerability of neurons, treatment of these diseases is usually aimed at slowing disease progression.

Infected burn wounds present significant clinical challenges due to delayed healing and risk of infection, necessitating advanced treatments that offer both antimicrobial and regenerative properties. This study aimed to develop and evaluate multifunctional electrospun nanofiber films incorporating rhamnose (as an angiogenic agent) and therapeutic agents, namely fluticasone, mupirocin, ciprofloxacin, and silver sulfadiazine, for the enhanced healing of infected burn wounds. Nanofibers containing rhamnose, polyacrylonitrile, polyvinyl alcohol and therapeutic agents were fabricated electrospinning.

Article Synopsis
- Pseudomonas aeruginosa is problematic in healthcare due to its high antibiotic resistance, highlighting the need for new antimicrobial solutions.
- A study focused on isolating a new bacteriocin from Enterococcus faecium found in stool samples, which showed promise against multidrug-resistant P. aeruginosa.
- The purified bacteriocin, enterocin GH, demonstrated significant antibacterial and antibiofilm activity against P. aeruginosa, outperforming controls in laboratory tests.

Chemotherapy is a potent tool against cancer, but drug resistance remains a major obstacle. To combat this, understanding the molecular mechanisms behind resistance in cancer cells and the protein expression changes driving these mechanisms is crucial. Targeting the Ubiquitin-Proteasome System (UPS) has proven effective in treating multiple myeloma and shows promise for solid tumours.

Aim: To investigate additional factors contributing to the pathophysiology of chemotherapy-induced oral mucositis and periodontitis beyond the systemic immune suppression caused by the chemotherapeutic agent 5-Fluorouracil (5-FU).
Methods: 5-Fluorouracil was topically delivered to the non-keratinized, rapidly proliferating junctional epithelium (JE) surrounding the dentition, and acts as an immunologic and functional barrier to bacterial ingression. Various techniques, including EdU incorporation, quantitative immunohistochemistry (qIHC), histology, enzymatic activity assays, and micro-computed tomographic (μCT) imaging, were employed to analyze the JE at multiple time points following topical 5-FU treatment.
