A liposomal formulation capable of encapsulating 76 to 92% of the antimycobacterial drug ethambutol and showing prolonged in vitro release kinetics is described. In vitro efficacy is equivalent to that of the free drug, suggesting that encapsulation of ethambutol has the potential to shorten the current regimens for tuberculosis.

Despite three decades of intense research, active targeting of liposomes have not been successfully achieved in a clinical setting. A potential explanation is that the clinically used liposomes lose their targeting abilities upon circulation. Here, we investigated if DSPE-PEG anchored antibody-based targeting ligands dissociate from clinically relevant drug delivery liposomes during circulation in mice.

The ionizable lipid component of lipid nanoparticle (LNP) formulations is essential for mRNA delivery by facilitating endosomal escape. Conventionally, these lipids are synthesized through complex, multistep chemical processes that are both time-consuming and require significant engineering. Furthermore, the development of new ionizable lipids is hindered by a limited understanding of the structure-activity relationships essential for effective mRNA delivery.

Arsenic trioxide (ATO), the active ingredient in Chinese arsenic, effectively inhibits hepatocellular carcinoma (HCC) cell growth, but its clinical application is limited by the lack of a targeted delivery system. Phosphatidylinositol proteoglycan 3 (GPC3) is specifically expressed in HCC, and CPP44 is a cell-penetrating peptide that targets HCC cells. Here, we developed a liposome incorporating ATO with dual surface modifications of anti-GPC3 antibody and CPP44.

Mucormycosis is an opportunistic fungal infection with high mortality, especially in immunocompromised patients. This article emphasizes the importance of early diagnosis and aggressive treatment. We describe the case of a child with leukemia treated with corticosteroids, vincristine, and daunorubicin, who developed rhino-orbital mucormycosis.

Objective: This systematic review analyzed phase III trials in platinum-resistant ovarian cancer to understand their poor outcomes and guide future trials.
Methods: A systematic review adhering to PRISMA guidelines was conducted. PubMed/Medline, Cochrane Library CENTRAL, and EMBASE were searched for randomized phase III trials (2010-January 2024) involving patients with platinum-resistant ovarian cancer.
