Hydroxypropyl methylcellulose acetate succinate (HPMCAS) has multi-disciplinary applications spanning across the development of drug delivery systems, in 3D printing, and in tissue engineering, etc. HPMCAS helps in maintaining the drug in a super-saturated condition by inhibiting its precipitation, thereby increasing the rate and extent of dissolution in the aqueous media. HPMCAS has several distinctive characteristics, such as being amphiphilic in nature, having an ionization pH, and a succinyl and acetyl substitution ratio, all of which are beneficial while developing formulations. This review provides insights regarding the various types of formulations being developed using HPMCAS, including amorphous solid dispersion (ASD), amorphous nanoparticles, dry coating, and 3D printing, along with their applicability in drug delivery and biomedical fields. Furthermore, HPMCAS, compared with other carbohydrate polymers, shows several benefits in drug delivery, including proficiency in imparting stable ASD with a high dissolution rate, being easily processable, and enhancing bioavailability. The various commercially available formulations, regulatory considerations, and key patents containing the HPMCAS have been discussed in this review.

The three-dimensional (3D) culture system has emerged as an indispensable platform for modulating stem cell function in biomedicine, drug screening, and cell therapy. Despite a few studies confirming the functionality of 3D culture, the molecular factors underlying this process remain obscure. Here, we have utilized a hanging drop method to generate 3D spheroid-derived mesenchymal stem cells (3D MSCs) and compared them to conventionally 2D-cultured MSCs.

Diabetes is a metabolic disorder of increasing global concern. Characterized by constantly elevated levels of glucose, severe β-cell dysfunction, and insulin resistance, it is the cause of a major burden on patients if not managed with therapeutic and lifestyle changes. The human body is slowly developing tolerance to many marketed antidiabetic drugs and the quest for the discovery of newer molecules continues.

The escalating threat of antimicrobial resistance demands innovative therapeutic strategies beyond classical targets. Recent insights into the mechanisms of bacterial iron acquisition - ranging from siderophores and heme uptake to ferrous iron transport - have enabled new approaches to impair pathogen growth and virulence. These pathways are increasingly being harnessed for therapeutic gain.

Background: Ultrasound-assisted transdermal drug delivery, or sonophoresis, enhances skin permeability, offering a non-invasive alternative for drug administration. However, its clinical application remains limited because of an insufficient understanding of its underlying mechanisms and optimal parameters. This study investigates the factors influencing ultrasound-enhanced drug absorption and examines its biological effects on skin structures and HaCaT cells, providing a comprehensive analysis of its mechanisms.

Immunotherapy has overturned the traditional perception of cancer treatment and brought new vitality to the field of oncology, but it still has unresolved problems such as a low response rate and severe side effects. The microbiome has been found to be involved in tumorigenesis, progression, metastasis and immunity modulation. Especially in immunity, the microbiome plays a key role through delicate mechanisms that regulate the immune response not only from the whole body to the local tumor microenvironment but also from innate to adaptive immunity.
