Summary: Life may not solely rely on biopolymers like RNA and proteins, as lipid assemblies could play a crucial role in the origin of life. Further investigation is needed to determine if lipid assemblies have protein-like capacities for specific interactions. Experimental evidence suggests that lipid aggregates have dynamic surface configurations capable of specific molecular recognition.

Summary: This study developed stable amphiphilic copolymer-based polymeric micelles with temperature-responsive properties using Pluronic (R) L35 and various ionic liquids. The partitioning and drug delivery capabilities of the micelles were investigated, with more hydrophobic ILs proving to be most effective. Different IL compositions affected the encapsulation efficiency, drug loading capacity, and release rate of the micelles, while Pluronic (R) L35 exhibited temperature responsiveness at 37.0 degrees C. In vitro cytotoxicity assays revealed different potency levels between formulations, demonstrating potential applications in drug delivery systems, encapsulation, and bioseparations.

Summary: Pluronic micelles show potential for hydrophobic drug delivery, with Pluronic P84 micelles being able to encapsulate naringenin and baicalein effectively. The solvent evaporation method (S.Ev.M) enhances drug encapsulation compared to the direct dissolution method (D.D.M.) and is a more convenient and efficient preparation method for drug-loaded Pluronic formulations.

Summary: A continuous polymeric micelle processing platform was developed to eliminate batch-to-batch variation in critical quality attributes. By controlling polymer molecular weight and concentration, precise particle size and low polydispersity were achieved. The optimized conditions produced paclitaxel polymeric micelles equivalent to commercial Genexol PM, with similar quality attributes.

Summary: This study investigated the potential effect of superparamagnetic iron oxide nanoparticles (SPIO) on the physical and biological properties of theranostic polymeric micelles. The results showed that SPIO formed hydrophobic geometric cavity in the micelle core, significantly affecting the integrity of the micelles and the drug loading capacity. In addition, SPIO enhanced drug absorption and prolonged the drug's half-life.

Summary: The study explored the role of the opioidergic system in anxiety-related behaviors. PDYN knockout mice had lower levels of certain MAPKs and FADD in the cortex and thalamus compared to normal mice. Exposure to stress stimuli activated certain signaling pathways, but this activation was reduced in PDYN-deficient mice. These findings suggest that neuroplasticity in cortical-thalamic regions is altered in PDYN-KO mice, and the PDYN gene is required for certain pathway activations under stress conditions.

Summary: This study aimed to evaluate the release profiles of two drug-loaded contact lenses (CLs) in a 3D in vitro eye blink model and compare them with in vivo profiles. The results showed that the release of both drugs was more sustained and lower in the 3D eye model compared to in vitro release in vials. The findings suggest that the current 3D printed eye blink model could be a useful tool to measure the release of ophthalmic drugs from medicated CLs, but further optimization is needed.

Summary: This study demonstrates the spontaneous formation of anisotropic gold nanoparticles (AuNPs) inside preformed contact lenses (CLs) without the need for additional reductant agents. The formation of AuNPs was achieved through a precise tuning of the monomeric composition, saline concentration, and the use of steam heat sterilization. The potential applications of incorporating AuNPs in CLs in the ocular field for prophylaxis, therapy, and diagnosis are highlighted. The developed CLs also exhibit photoresponsiveness and efficient filtering of highly penetrant light.

Summary: In this study, the researchers investigated the potential effects of two I2 drugs, CR4056 and B06, on male and female rats exposed to early-life stress. They found that CR4056 showed antidepressant-like effects in both male and female rats, but its efficacy in females was dependent on prior early-life stress exposure. In contrast, B06 had no antidepressant-like effects in either male or female rats. The study also identified some molecular differences underlying the therapeutic response of CR4056 between sexes.

Summary: The aim of this study was to develop cationic niosomes for the ocular delivery of epalrestat, a drug used in the treatment of diabetic eye damage. The niosomes were characterized and found to have a size of 80 nm, a charge ranging from -23 to +40 mV, and a spherical shape. The encapsulation efficiency of the niosomes was 99.76% and they showed a sustained release of the drug over 20 days. The niosomes were non-irritating, non-toxic, and showed higher permeation in the sclera compared to the unencapsulated drug.

Summary: This review focuses on the recent advances in pH-responsive polymer-based scaffolds that have been demonstrated in vivo to be suitable for wound and bone healing. pH plays a critical role in the tissue regeneration process, and small changes can significantly impact the healing process. Various strategies, including changes in ionization of natural polymers, ionizable monomers and clays, reversible cross-linkers, coatings, and production of CO2 gas, have been tested to prepare pH-responsive scaffolds. These techniques have shown promise in achieving biocompatible and environment-friendly scaffolds that can be translated to clinical applications.
