In today's pharmaceutical arena, it is estimated that more than 40% of new chemical entities produced during drug discovery efforts exhibit poor solubility characteristics. However, over the last decade hot-melt extrusion (HME) has emerged as a powerful processing technology for drug delivery and has opened the door to a host of molecules previously considered unviable as drugs. HME is considered to be an efficient technique in developing solid molecular dispersions and has been demonstrated to provide sustained, modified and targeted drug delivery resulting in improved bioavailability. This article reviews the range of HME applications for pharmaceutical dosage forms, such as tablets, capsules, films and implants for drug delivery through oral, transdermal, transmucosal, transungual, as well as other routes of administration. Interest in HME as a pharmaceutical process continues to grow and the potential of automation and reduction of capital investment and labor costs have made this technique worthy of consideration as a drug delivery solution.

Radiation resistance in head and neck squamous cell carcinoma (HNSCC), driven by intrinsic and extrinsic factors, poses a significant challenge in radiation oncology. The key contributors are tumor hypoxia, cancer stem cells, cell cycle checkpoint activation, and DNA repair processes (homologous recombination and non-homologous end-joining). Genetic modifications such as TP53 mutations, KRAS mutations, EGFR overexpression, and abnormalities in DNA repair proteins like BRCA1/2 additionally affect radiation sensitivity.

The therapeutic efficacy of drugs is highly dependent on their successful delivery to the target site. However, achieving targeted drug delivery to diseased areas remains a significant challenge. Current drug delivery systems based on nanocarriers often suffer from inefficiencies due to their lack of intrinsic propulsion and active targeting capabilities.

Background: Osteosarcomas (OS) are malignant bone tumors prevalent in adolescents, characterized by aggressiveness and early metastasis. Current treatments including surgery and chemotherapy face challenges due to drug limitations and the complex tumor microenvironment (TME).
Methods: Tumour membranes (TM) derived from OS cells and macrophage membranes (MM) derived from macrophages were mixed to create hybrid membranes (HM), which were subsequently used to encapsulate microRNA-665(miR-665)-loaded Poly lactic-co-glycolic acid (PLGA) nanoparticles, forming HM@PLGA/miR-665 complexes.

DNA nanotechnology has created new possibilities for the use of DNA in tissue regeneration - an important advance for DNA use beyond its paradigmatic role as the hereditary biomacromolecule. Biomaterials containing synthetic or natural DNA have been proposed for several applications including drug and gene delivery, and more recently, as osteoconductive biomaterials. This review provides an in-depth discussion of studies that have used DNA-based materials for biomineralization and/or bone repair, with expansion on the topic of DNA hydrogels specifically, and the advantages they offer for advancing the field of bone regeneration.

Breast cancer remains a significant challenge in oncology, despite notable advances in treatment methods. Traditional therapies such as surgery, chemotherapy, radiation, and hormonal treatments have long been used to manage breast cancer. However, often patients experience treatment failure, resulting in disease recurrence and progression.
