Recombinant DNA: unlocking untapped microbial potential for innovation in crop agriculture.

The Asilomar Conference on Recombinant DNA, held in 1975, established guidelines for recombinant DNA (rDNA) research and laid the foundation for biotechnology regulations. While rDNA has driven significant advancements in pharmaceutical and crop biotechnology, the commercialization of plant-beneficial microbials developed using rDNA has lagged behind. This disparity may be attributed to a cumbersome regulatory framework shaped by the perception that rDNA products pose biosafety risks.

A Theoretical Approach in Applying High-Frequency Acoustic and Elasticity Microscopy to Assess Cells and Tissues.

Medical ultrasound is a diagnostic imaging modality used for visualizing internal organs; the frequencies typically used are 2-10 MHz. Scanning acoustic microscopy (SAM) is a form of ultrasound where frequencies typically exceed 50 MHz. Increasing the acoustic frequency increases the specimen's spatial resolution but reduces the imaging depth.

Voices of Nanomedicine: Blueprint Guidelines for Collaboration in Addressing Global Unmet Medical Needs.

The "" under this Perspective underline the importance of interdisciplinary collaboration and partnerships across several disciplines, such as medical science and technology, medicine, bioengineering, and computational approaches, in bridging the gap between research, manufacturing, and clinical applications. Effective communication is key to bridging team gaps, enhancing trust, and resolving conflicts, thereby fostering teamwork and individual growth toward shared goals. Drawing from the success of the COVID-19 vaccine development, we advocate the application of similar collaborative models in other complex health areas such as nanomedicine and biomedical engineering.

Controlled Nutrient Delivery to Pancreatic Islets Using Polydopamine-Coated Mesoporous Silica Nanoparticles.

In this study, we designed a nanoscale platform for sustained amino acid delivery to support transplanted pancreatic islets. The platform features mesoporous silica nanoparticles (MSNPs) loaded with glutamine (G), an essential amino acid required for islet survival and function, and coated with polydopamine (PD). We investigated various PD concentrations (0.
