The simple method to manufacture a flexible multi-drug with hydrophilic and hydrophobic molecules-loaded composite membrane via three dimensional (3D) electrohydrodynamic (EHD) printing has been demonstrated in this study. The composite membrane consists of two different drug-loaded sections: cellulose acetate-ibuprofen (CA-IBU) and cellulose acetate-paracetamol (CA-Para), respectively, with an intermediate polycaprolactone (PCL) folding component. The composite membranes can be folded and housed in commercial capsules to aid swallowing. By changing the number of PCL layers in the intermediate layers, it is possible to control and modify the mechanical and unfolding properties of the composite membrane. IBU and Para are loaded into the CA polymeric matrix in their amorphous states, with the matrices exhibiting Higuchi and first order release kinetics, respectively. The combination of IBU and Para can potentially be used as analgesic for patients. Magnetic nanoparticles as a functional material can be incorporated into the PCL matrix for wide targeting and traceable applications. The composite membrane here possesses good biocompatibility and flexibility; enabling extensive application prospects in drug combination therapy and personalized medicine.

Balancing Activity and Stability through Compositional Engineering of Ternary PtNi-Au Alloy ORR Catalysts.

Achieving the optimal balance between cost-efficiency and stability of oxygen reduction reaction (ORR) catalysts is currently among the key research focuses aiming at reaching a broader implementation of proton-exchange membrane fuel cells (PEMFCs). To address this challenge, we combine two well-established strategies to enhance both activity and stability of platinum-based ORR catalysts. Specifically, we prepare ternary PtNi-Au alloys, where each alloying element plays a distinct role: Ni reduces costs and boosts ORR activity, while Au enhances stability.

Aquaculture is one of the world's fastest-growing sectors in food production but with multiple challenges related to animal handling and infections. The disease caused by infectious salmon anemia virus (ISAV) leads to outbreaks of local epidemics, reducing animal welfare, and causing significant economic losses. The composition of feed has shifted from marine ingredients such as fish oil and fish meal towards a more plant-based diet causing reduced levels of eicosapentaenoic acid (EPA).

The Indian scad, Decapterus russelli is one of the most exploited pelagic resources of India. Population genetic analyses using mitochondrial and nuclear markers indicated a lack of genetic structuring among populations from Indian waters. As this species is highly migratory, it is also important to establish the environmental influence on its population structure.

Multidrug resistance-associated protein 2 (MRP2) is an ATP-powered exporter important for maintaining liver homeostasis and a potential contributor to chemotherapeutic resistance. Using cryogenic electron microscopy (cryo-EM), we determine the structures of human MRP2 in three conformational states: an autoinhibited state, a substrate-bound pre-translocation state, and an ATP-bound post-translocation state. In the autoinhibited state, the cytosolic regulatory (R) domain plugs into the transmembrane substrate-binding site and extends into the cytosol to form a composite ATP-binding site at the surface of nucleotide-binding domain 2.

Facile Preparation of Sulfonated Polysulfone Composite Membranes with High Hydrophilicity and Visible-Light Driving Self-Cleaning Performance.

ACS Appl Mater Interfaces

The photo-Fenton reaction can efficiently degrade organic pollutants and thus is applied intensively for clearing out membrane fouling. However, the pollutant removal efficiency is greatly limited by the redox cycle rate of Fe/Fe and the rapid recombination rate of the photogenerated electrons and holes. In order to overcome these drawbacks, a sulfonated polysulfone composite membrane was designed and prepared by incorporating titanium dioxide (TiO) nanoparticles into a sulfonated polysulfone membrane and sequentially forming β-FeOOHs on the membrane surface.
