The improvement of pharmaceutical dosage forms, such as tablets, towards drug delivery control and cost efficiency is of great importance in formulation technologies. Here, three examples: in situ coating, freeze casting and protein-based biocomposites are presented that address the above mentioned issues and contribute to further developments in formulation technologies. The in situ coating increases the economic efficiency by saving process steps in comparison to a conventional tableting process and provides a crystalline coating for a tailorable drug delivery rate. The freeze casting allows the control over the surface area of a drug delivery system (DDS) by providing different numbers and sizes of pores, which in conjunction with adequate additives offer an efficient instrument for drug delivery control, especially by accelerating the dissolution effect. Protein-based biocomposites are attractive materials for biomedical and pharmaceutical applications that can be applied as a polymeric DDS. They inherently combine degradability in vivo and in vitro, show a good biocompatibility, offer sites of adhesion for cells and may additionally be used to release embedded bioactive molecules. Here, a new approach regarding the incorporation of crystalline active pharmaceutical ingredients (API) into a protein matrix in one process step is presented. All three presented techniques mark decisive progress towards tailor-made drug delivery systems with respect to function, economic efficiency and the generation of additional values.

Chronic kidney disease (CKD) ultimately causes renal fibrosis and end-stage renal disease, thus seriously threatens human health. However, current medications for CKD and fibrosis are inefficient, which is often due to poor targeting capability to renal tubule. In this study, we discover that biomimetic high-density lipoprotein (bHDL) lipid nanoparticles possess excellent targeting ability to injured tubular epithelial cells by kidney injury molecule-1(KIM-1) mediated internalization.

Objectives: Characterise US residents' exposure to restrictions on sales of flavoured electronic nicotine delivery system (ENDS), cigars and menthol cigarettes across states and time, and assess correlations between these policies.
Methods: From 2022 to 2024, we compiled flavour policy locations from advocacy groups and online searches, located corresponding legal texts and reviewed these to identify policy details, including effective dates. Using census data, we calculated the proportion of state residents covered by each policy quarterly from 2009 to 2024 and estimated correlations between them and cigarette taxes.

A woman in her 40s presented with severe post-bariatric hypoglycaemia that persisted despite nutritional therapy and pharmacological therapy with acarbose and subcutaneous octreotide with meals. The nutritional limitations were difficult to sustain, and she developed adverse effects to the pharmacological therapy, and hence, doses could not be increased. She was subsequently treated with subcutaneous octreotide via an insulin pump, with a continuous basal rate and additional bolus doses with meals.

Lignocellulosic biomass represents one of the most abundant renewable biological resources on earth. Despite its current underutilization as a source of high-value chemicals, it has promising applications in biomedical and other fields. Presently, lignocellulose is predominantly transformed into high-value-added products, e.

Colorectal cancer (CRC) remains a significant public health concern, emphasizing the need for innovative therapeutic strategies to improve patient outcomes. This study aimed to develop a highly efficient nanocarrier for targeted drug delivery, enhancing drug efficacy while minimizing concentrations and limiting adverse effects. We synthesized protein-based β-lactoglobulin (βlg) nanoparticles (NPs), loaded with 5-fluorouracil (5-FU) and sodium butyrate (NaB), and further functionalized with folic acid (FA) for specific targeting of folate receptor-positive CRC cells.
