Summary: A study has developed an intestinal stent loaded with a combination of traditional Chinese medicines for the treatment of intestinal tumors. The stent, made using emulsion electrospinning technology, has a core-shell structure and sustained drug release properties. In vitro tests have shown that the drug-loaded membrane effectively inhibits tumor cell growth.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.

Summary: This in-vitro study evaluates the effect of reactive oxygen species (ROS) on the structural rearrangement of elastin. The results show that oxidative stress leads to a decrease in protein size and changes in secondary structure, potentially promoting protein aggregation. This study is important for therapeutics aiming to prevent elastin degradation and aging.

Summary: This study aimed to enhance the specific interactions between human hepatocellular carcinoma cell lines (HepG-2) by preparing and investigating the fluorescence emission properties of the Ag-Au-ICG complex. The complex was prepared via physical adsorption and evaluated for fluorescence spectra. The addition of an optimized dosage of Ag-Au-ICG to HepG-2 resulted in maximum fluorescence signal intensity and enhanced contrast fluorescence. The complex showed low cytotoxicity, making it a potential fluorescence enhancer for liver cancer imaging.

Summary: Atherosclerosis (AS) is the main pathological basis for cardiovascular and cerebrovascular diseases, significantly affecting human health. Using bioinformatics, 74 key genes were identified that are mainly involved in regulating inflammatory response, chemokine signalling pathway, apoptosis, lipid and AS, Toll-like receptor signalling pathway, etc. Four pivotal genes (TYROBP, ITGB2, ITGAM, and TLR2) were screened as therapeutic targets for AS based on their correlation with immune-related biological functions and signal pathways, as well as infiltration level of immune cells.

Summary: As an autoimmune disease, the incidence of ulcerative colitis (UC) remains high. Carbon dots (CDs), a new type of nanomaterials, show potential as a new treatment for UC. The use of carbonized rhei radix rhizoma (RRR) and extracted CDs (RRR-CDs) display significant anti-ulcerative activity in a UC mouse model. This suggests that RRR-CDs could be a candidate drug for UC treatment, expanding the understanding of the biological activity of CDs and providing a potential solution for difficult clinical diseases.

Summary: Bee propolis, a natural substance used in alternative medicine, has limited water solubility which causes skin irritation and immune response when combined with alcohol solvents. To overcome this issue, researchers developed a new drug delivery system based on lipid nanodiscs, which showed improved encapsulation efficiency and non-toxicity in low doses. These nanodiscs can enhance the solubility and therapeutic effects of poorly water-soluble drugs.

Summary: Passive techniques for administering photosensitizers (PSs) in photodynamic therapy (PDT) are becoming less viable as concerns about PDT resistance increase. In this study, a multifunctional photosensitizing agent was developed by binding PEGylated Gold Nanoparticles (PEGy-AuNP), anti-E6 monoclonal antibodies (mAbs), and phthalocyanines together. This compound showed enhanced internalization of PS, leading to improved PDT effects.

Summary: Osteoporosis, a common disease in the ageing society, is caused by oxidative stress due to excessive accumulation of reactive oxygen species (ROS). Alpha-lipoic acid (ALA) is an antioxidant that can eliminate excess ROS and inhibit oxidative stress. In this study, PEGylated hollow gold nanoparticles (HGNPs) loaded with ALA were designed to treat osteoporosis. The results showed that mPEG@HGNPs-ALA had good biocompatibility and the ability to reduce oxidative stress.

Summary: The study synthesized and characterized zinc oxide nanoparticles (ZnO NPs) using spinach tree and investigated their potential use as nanofertilizer. The synthesized NPs showed UV-Vis absorption at 378 nm, indicating their identity as ZnO NPs. FT-IR analysis revealed the presence of functional groups of the plant extract on the surface of the NPs. SEM images showed spherical shape, while TEM images showed a distribution size of 100 nm. The application of ZnO NPs as a nano fertilizer on Sorghum bicolour plant resulted in increased shoot leaf length, higher photosynthetic rate, and increased SOD activity.

Summary: Gynaecological cancers pose a major global health concern, with inadequate screening and diagnostic methods for ovarian, endometrial, and cervical cancer. Portable and cost-effective lab-on-a-chip (LoC) technologies show promise for mass screening and diagnosis of gynaecological cancers. However, further research and validation are needed before widespread adoption in clinical practice.
