Regeneration of the injured endometrium, particularly the functional layer, is crucial for the prevention of uterine infertility. At present, clinical treatment using sodium hyaluronate hydrogel injection is limited by its relatively low fluidity, short-term retention, and insufficient bioactive ingredients, so it is necessary to develop an advanced healing-promoting hydrogel. The modulation of the microenvironment by presents a bioactive component that can facilitate the regeneration of the functional layer.

Background Heart failure (HF) is commonly managed by addressing water and sodium (Na) balance, with arterial circulation playing a major role in influencing renal Na and water excretion. Recently, chloride (Cl) has been recognized as an important factor in HF, associated with volume regulation and its modulation of renin-angiotensin-aldosterone system (RAAS) activity through macula densa signaling, which impacts Na retention and neurohormonal activation. Acetazolamide, a carbonic anhydrase inhibitor, can enhance decongestion in HF by increasing urinary Na and Cl excretion when added to loop diuretics, a mechanism supported by prior studies demonstrating improved urine output and decongestion.

Eutectogels are recently emerged as promising alternatives to hydrogels owing to their good environmental stability derived from deep eutectic solvents (DES). However, construction of competent eutectogels with both high conductivity and mechanical toughness is still difficult to achieve yet highly demanded. In this work, new LMNP-PEDOT-CMC-AA (LPCA) eutectogels are prepared using acrylic acid (AA) and carboxymethylcellulose sodium (CMC) as polymeric networks, liquid metal nanoparticle-poly(3,4-ethylenedioxythiophene) (LMNP-PEDOT) are added as multifunctional soft fillers.

The local structure plays a crucial role in oxygen redox reactions, which boosts the capacity of layered oxide cathodes for sodium-ion batteries. While studies on local structural ordering have primarily focused on the intra-layer ordering, there has been limited research on the inter-layer stacking for the layered cathode materials for sodium-ion batteries. In this work, the impact of the intra-layer and inter-layer local structural regulation on anionic kinetics and the structure stability are explored through experimental analysis and theoretical calculations.

Thiomatrix Forschungs- und Beratungs GmbH, Trientlgasse 65, 6020, Innsbruck, Austria.
Aim: It was the aim of this study to compare two different dry reverse micelle (RM) preparation methods for the incorporation of hydrophilic drugs into oral self-emulsifying drug delivery systems (SEDDS).
Methods: Cationic ethacridine lactate, anionic fluorescein sodium salt and the antibiotic peptide bacitracin were solubilized in RM containing sodium docusate, soy phosphatidylcholine and sorbitan monooleate in highly lipophilic oils such as squalane. In the dry addition (DA) method, drugs were directly added to empty RM in their powder form.
