Harnessing the Potential of Natural Composites in Biomedical 3D Printing.

Natural composites are emerging as promising alternative materials for 3D printing in biomedical applications due to their biocompatibility, sustainability, and unique mechanical properties. The use of natural composites offers several advantages, including reduced environmental impact, enhanced biodegradability, and improved tissue compatibility. These materials can be processed into filaments or resins suitable for various 3D printing techniques, such as fused deposition modeling (FDM).

Self-Assembly of Homo Phenylalanine Oligopeptides: Role of Oligopeptide Chain Length.

The self-assembly of phenylalanine (F)-based peptides is a critical area of research with potential implications for the development of advanced biomaterials and technologies. Previous studies indicate that homo-oligopeptides with F-X residues (X = 1 to 6) can self-assemble into diverse nano-microstructures, but the role of oligopeptide chain length on this process remains unclear. This review investigates the role of F-X chain length on self-assembly processes and morphologies, considering the effect of incubation conditions and the capping group at the N and/or C terminals.

Factors Influencing Nurses' Knowledge About Delirium in Acute Care Settings in Hail Region, Saudi Arabia: A Cross-Sectional Study.

Background: The factors influencing nurses' knowledge of delirium in acute care settings have not been fully investigated in Saudi Arabia. Therefore, this study aimed to investigate these factors among nurses in acute care settings in the northern region of Saudi Arabia.

Methodology: A cross-sectional study was conducted using a convenience sample of 234 acute care nurses at the main public hospitals in the Hail region of Saudi Arabia.

Single/joint effects of pyrene and heavy metals in contaminated soils on the growth and physiological response of maize ( L.).

The widespread presence of polycyclic aromatic hydrocarbons (PAHs) and toxic heavy metals in soils is having harmful effects on food crops and the environment. However, the defense mechanisms and capacity of plants to counteract these substances have not been comprehensively explored, necessitating a systematic categorization of their inhibitory effects. Accordingly, an experimental investigation was conducted to examine the growth and physiological response of maize ( L.
