Summary: High-nitrogen nickel-free stainless steel (HNNFSS) is a new type of high-performance biomedical metallic material that replaces nickel with nitrogen and manganese to stabilize the structure. It has better mechanical properties, corrosion resistance, and biocompatibility. Numerous studies have shown that HNNFSS implants have stronger adhesion to surrounding tissues, promoting new bone formation, while HNNFSS vascular stents have lower restenosis rate and superior blood compatibility.

Summary: Localized corrosion of 316L stainless steel reduces the viability, adhesion, proliferation, and osteogenic differentiation abilities of BMSCs. It causes cytotoxicity through the release of metallic ions and generates reactive oxygen species (ROS) around the corrosion pits, leading to oxidative stress and cell membrane depolarization. This study provides insights into corrosion-mediated degradation of cell function and material-cell interactions.

Summary: Terahertz (THz) technology is a non-invasive imaging system that shows great potential for biosensing and clinical diagnosis. It is particularly effective in detecting changes in water content and structural variations in diseased cells, making it useful for early detection of pathologic tissue, especially in oncology. However, THz imaging has limited contrast in living tissue for in-vivo clinical imaging. Nanotechnology has emerged as a solution to enhance the accuracy and specificity of THz images by using nanoparticles as contrast agents.

Summary: This study investigated the use of a novel biomimetic hybrid scaffold for skin regeneration, which continuously delivered stromal cell-derived factor-1 alpha (SDF-1 alpha). The scaffold demonstrated biocompatibility and its release of SDF-1 alpha was assessed. In diabetic rat models, the scaffold with SDF-1 alpha showed a significantly enhanced ability for wound regeneration and recruitment of CD31 and CXCR4-positive cells. The study concluded that the hybrid scaffold based on natural polymer offers a new option for topical administration of bioactive molecules and holds promise for skin tissue engineering.

Summary: Scaffolds play a crucial role in tissue engineering by providing an environment for cell growth and function. Coating tissue engineering scaffolds with poly(lactic-co-glycolic acid) (PLGA) has been found to be an effective method to improve scaffold properties. This review examines the techniques used to coat scaffolds with PLGA and its impact on mechanical characteristics, biodegradability, biocompatibility, molecular delivery, and osteointegration. The results indicate that all bio-functionalities can be modified through PLGA coatings, highlighting the potential of this approach in tissue regeneration and therapeutic delivery applications.

Summary: The aim of this study was to synthesize chemically activated carbons from different agricultural residues and use them as supports for loading a Ni catalyst. The results showed that the activated carbons had considerable pore structures and the Ni/AC(PS) catalyst showed a superior catalytic activity. By raising the process temperature, the total amount of gas and hydrogen increased, and the highest total gas amount was achieved using Ni/AC(PS) at T = 550 degrees C.

Summary: 3D printing is an advanced technology used to fabricate biomaterials for translational medicine. With the introduction of stimuli-responsive properties, known as 4D printing, intelligent biomaterials with time-dependent characteristics have been developed. Polysaccharides, which are sensitive to various stimuli, are suitable for 3D and 4D printing. However, the mechanical strength and printability of polysaccharide-based scaffolds, as well as their aneural, avascular, and poor metabolic characteristics, need to be optimized by varying printing parameters. Multiple disciplines need to be integrated to achieve multipurpose printable biomaterials.

Summary: Breast cancer is a prevalent cancer in women, and microfluidic devices show promise in advancing research in this field. This study used a dynamic cell culture condition in a microfluidic concentration gradient device to assess the anticancer activities of probiotic strains against breast cancer cells. The findings revealed that a specific concentration of probiotic supernatant induced more cell death signaling after 48 hours. Additionally, the evaluated optimum dose was lower than the conventional treatment dose. Flow cytometric assessment confirmed that cell death signaling was concentration and time dependent. This study demonstrates the potential benefits of microfluidic platforms in personalized medicine and cancer therapy.

Summary: The regeneration of oral and craniofacial bone defects imposes a global health burden, and conventional therapies have limitations, highlighting the need for unique treatment strategies like tissue engineering. Mesoporous silica nanoparticles (MSNs) were found to enhance the mechanical strength of scaffolds without decreasing porosity. The MSN-containing scaffolds exhibited desirable swelling behaviors, low hydrolytic degradation, and no cytotoxicity. Therefore, Alg/Chit/MSN30 scaffolds are considered promising for bone tissue regeneration.
