Nanotechnology has potential in the development of novel and effective delivery of drugs within lungs. Different strategies have been utilized for pulmonary delivery of drugs, including the use of lipid-based delivery systems (liposomes, ISCOMs, SLNs), use of polymeric matrix (PLGA, poly caprolactone, cynoacrylates, gelatin), development of polysaccharide particulates (chitosan, alginates, Carbopol, etc.), biocompatible metallic inorganic particles (iron, gold, zinc), etc. This paper reviews various nanopaticulate approaches in the form of lipids, polymers, metals, polysaccharides, or emulsions based for pulmonary drug delivery that could provide an increased biological efficacy and better local and systemic action.

mRNA-based protein replacement therapy has become one of the most widely applied forms of mRNA therapy, with lipid nanoparticles (LNPs) being extensively studied as efficient delivery platforms for mRNA. However, existing LNPs tend to accumulate in the liver or kidneys after intravenous injection, highlighting the need to develop vectors capable of targeting specific organs. In this study, we synthesized a small library of ionizable lipids and identified PPz-2R as a promising candidate, exhibiting lung-targeting capabilities, high mRNA transfection efficiency, and good stability through structure-activity relationship studies.

Irreversible electroporation (IRE) is a novel local tumor ablation technique that can potentially stimulate immune responses. However, IRE alone cannot effectively activate the immune system or prevent distant metastases. Therefore, this study utilized the biocompatibility of Chlorella vulgaris (C.

Atherosclerosis is one of the leading causes of ischemic cardiovascular disease worldwide. Recent studies indicated that vascular smooth muscle cells (VSMCs) play an indispensable role in the progression of atherosclerosis. Exosomes derived from mesenchymal stem cells (MSCs) have demonstrated promising clinical applications in the treatment of atherosclerosis.

Splice-switching oligonucleotides (SSOs) can restore protein functionality in pathologies and are promising tools for manipulating the RNA-splicing machinery. Delivery vectors can considerably improve SSO functionality in vivo and allow dose reduction, thereby addressing the challenges of RNA-targeted therapeutics. Here, we report a biocompatible SSO nanocarrier, based on redox-responsive disulfide cross-linked low-molecular-weight linear polyethylenimine (cLPEI), for overcoming multiple biological barriers from subcellular compartments to en-route serum stability and finally in vivo delivery challenges.

Cancer is a global public health concern with increasing incidence and mortality rates, particularly in low- and middle-income countries (LMICs) like the Pacific Island Countries and Territories (PICTs). Among the PICTs, Fiji faces a growing burden of cancer. This study aimed to analyze cancer incidence and mortality data in Fiji from 2010 to 2018 to identify trends and provide an update on the current cancer-related statistics in the Fiji Islands.
