The aim of this work was to evaluate the in vitro performance of a nebulized nanoemulsion formulation which had been optimised previously. To do so, a transparent nanoemulsion preparation containing 1.5 mg/ml of budesonide was prepared and diluted to achieve concentrations of 250 and 500 μg/ml budesonide. The in vitro characteristics of the diluted nanoemulsions were then compared with the commercially available suspension of budesonide (Pulmicort Respules®) when nebulized using a jet and a vibrating mesh nebulizer. A smaller MMAD with improved aerosol output was observed in the nanoemulsion preparations compared with the corresponding suspension formulations indicating an improved in vitro performance for the nanoemulsion-based preparations.

Hepatocellular carcinoma (HCC) remains a malignant and life-threatening tumor with an extremely poor prognosis, posing a significant global health challenge. Despite the continuous emergence of novel therapeutic agents, patients exhibit substantial heterogeneity in their responses to anti-tumor drugs and overall prognosis. The pentose phosphate pathway (PPP) is highly activated in various tumor cells and plays a pivotal role in tumor metabolic reprogramming.

Exudate management is essential for creating a moist wound environment that promotes optimal healing, especially in highly exuding wounds, where choosing an appropriate wound dressing to handle high volumes of exudate is a key part of the wound management strategy. Superabsorbent wound dressings (SWDs) have been designed to absorb and retain large amounts of exudate. Thus, they are advocated for management of wounds with moderate-to-high levels of exudate to reduce the risk of leakage and damage to the periwound skin.

Primase-polymerases (PrimPols) play divergent functions from DNA replication to DNA repair in all three life domains. In archaea and bacteria, numerous and diverse PPs are encoded by mobile genetic elements (MGEs) and act as the replicases for their MGEs. However, their varying activities and functions are not fully understood.
