A Micro/Nanobubble Oxygenated Solutions for Wound Healing and Tissue Preservation

Soft-tissue injuries and organ transplantation are common in modern combat scenarios. Organs and tissues harvested for transplantation need to be preserved during transport, which can be very difficult. Micro and nanobubbles (MNBs) offer a new technology that could supply oxygenation to such tissues prior to transplantation, thus affording better recovery and survival of patients. Described here is a novel device capable of producing MNB solutions that can be used to preserve viability and function of such organs/tissue. Additionally, these solutions may be used with negative pressure wound therapy to heal soft-tissue wounds.

Remotely-Activated Cell Therapy

The remote control of cellular activation in a controllable and reproducible fashion is a key tool for biological research, as well as for therapeutic uses. Cellular therapies are becoming well established within the medical community. However, the degree of cellular activation can be an unknown factor, and the risk of off-target effects remains. Cells may be delivered, but may not be therapeutically effective, or effective cells may elicit activity in an undesired location. The delivery of a cell therapy where a known quantity of cell activation occurs at a specific, selected site may therefore be advantageous. UC San Diego researchers have recently developed the methods and materials for remote control of cellular activation, to dynamically manipulate molecular events for therapeutic effect.

Nanoparticle-Loaded Cellular Delivery System of Pt(II) Chemotherapeutic Drugs

Major challenges of treating ovarian carcinomas by the use of intraperitoneal (IP) chemotherapy (e.g. injecting chemo drugs into the abdominal cavity through a catheter) include how to retain the drug in the cavity for longer periods of time, how to concentrate it onto the tumor nodules growing on the peritoneal surface, and how to enhance its penetration from the free surface of the nodule. Drug loaded nanomaterials are generally obtained by encapsulation of the drug during formulation of the particle via non‐covalent adsorption or passive entrapment. A limitation of these loading strategies is the burst release of drug, where an important fraction of the loaded compound is released in a short amount of time due to the inherently weak forces keeping the drug associated with the nanocarrier. In addition, for metal based drugs, loaded polymeric nanomaterials can be generated via a post‐polymerization reaction of an activated metal complex with an activated ligand moiety on the polymer backbone. In this case, inherent to the technique, is the lack of control of the type of ligand (monodentate, bidentate) and complex (interstrand or intrastrand), which are obtained. However, the main drawback to these approaches is the typically low and uncontrolled encapsulation efficacy, which is a severe limitation for large‐scale production and reproducibility that hinders the development of clinically appropriate formulations.

Finite-State Machines For DNA Information Storage

DNA can store petabytes of information per gram and can last intact for tens of thousands of years.  This makes it an appealing prospect for long-term archival storage.  However, DNA synthesis, sequencing, and replication are prone to errors, which limit its potential as a storage medium.  These errors can be controlled by applying the tools of information theory, treating DNA storage as a noisy channel coding problem.  Several coding schemes for DNA storage have been proposed that address the interrelated issues of error avoidance, error correction and redundancy.  There are currently no schemes that address all the above.    Researchers at UC Berkeley have combine some of these ideas, and introduced new ones, using a modular strategy for code design.  With this method, codes can be assembled to meet requirements including error-avoidance, error-correction (resistant to corruption of the information by substitutions, insertions, duplications, or deletions that are introduced during sequencing or replication of the DNA), and demarcation of metadata.  The DNA generated by the codes is free of short local repeats and other (foldback) structure.  The codes generated by this method are flexible in that they arise by systematic combination of state machines, each machine formally representing a particular transformation of the input sequence.  So, for example, one state machine might be used to introduce a "watermark" signal that helps protect against insertion/deletion errors; another state machine could be used to convert the binary sequence into a ternary sequence (or mixed-radix sequence); another state machine would convert the ternary or mixed-radix sequence into a non-repeating DNA sequence; and another state machine to model the errors that are introduced during sequencing.

Cell Membrane-cloaked Nanofibers Promote Cell Proliferation and Function

Cloaking of synthetic structures with natural cell membranes has emerged as an intriguing strategy for presenting natural cell surface antigens and functions in the context of synthetic compositions with designed functions. Early forays into the field focused primarily on the development of cell membrane-coated spherical nanoparticles. While a boon to material sciences, such spherical structures cannot address the full spectrum of potential applications and the application of cell membrane cloaking techniques to nanofibers enables drastically different characteristics and applications.
