Transfection activities of two series of synthetic glycerol backbone-based cationic lipids were studied as gene delivery carriers. The variable length of hydrocarbon chains, diverse quaternary ammonium heads, different linkage, as well as alternative anion combined with them allowed to find how these factors affect cationic lipids on their gene delivery performance. The structure-function relationship of the synthetic glycerol backbone-based cationic lipids was discussed, and the transfection efficiency of some of the cationic liposomes was superior or parallel to that of two commercial transfection agents.

Introduction: Sepiolite nanofibers, which are natural silicates belonging to the clay mineral family, could be promising potential nanocarriers for the nonviral transfer of biomolecules. The physicochemical characteristics of sepiolite make it capable of binding various types of biological molecules, including polysaccharides, lipids, proteins and viruses. Sepiolite nanofibers have also been shown to bind effectively to various types of DNA molecules through electrostatic interactions, hydrogen bonds, cationic bridges and van der Waals forces.

In recent decades, the recurrence and mortality rates of fungal infections have increased, likely due to antifungal resistance and insufficient attention from healthcare authorities. This trend highlights the urgent need for new antifungal treatments, with essential oils (EOs) emerging as promising alternatives. This study focuses on the characterization, nanoencapsulation, and evaluation of the EO of Kunth - pepper-rosemary - on toxicity and antifungal activity against filamentous fungi and yeasts, with a particular emphasis on the influence of surfactants.

One of the key challenges in using natural extracts for water treatment is their biodegradability and susceptibility to microbial spoilage, which can limit storage and long-term effectiveness. This study investigates the scale inhibition capabilities of an aqueous extract of Salvia rosmarinussp through electrochemical measurements, conductivity tests, and morphological examination. Additionally, two natural substances, Rhamnolipid and Chitosan, were evaluated as bio-preservatives to prevent mold growth and enhance the shelf life of the rosemary extract.

Diabetic liver disease is a common complication of diabetes mellitus that poses significant harm to patients. Transient receptor potential cation channel 6 (TRPC6) is a non-selective cation channel with calcium permeability, playing a key role in signalling pathways associated with liver disease progression. This study aimed to investigate the effects of Trpc6 knockout on liver injury and its regulation of the calcineurin (CN)-nuclear factor of activated T cells 2 (NFAT2) signalling pathway in mice with type 2 diabetes mellitus (T2DM).

Lipid nanoparticles (LNPs) have been successful in delivering nucleic acids like siRNA and mRNA, but face challenges in protein delivery due to limited protein encapsulation and endosome escape. In this study, a family of LNPs is developed with robust high efficiency in addressing the multiple barriers in cytosolic protein delivery by incorporating clinically approved ionizable lipids into traditional cationic LNPs. The combination of cationic and ionizable lipids enables efficient protein binding and endosomal escape.
