Switchable Chimeric Antigen Receptor-Engineered Human Natural Killer Cells

The existing CAR-engineered T cell-based (CAR-T) therapy represents one of the most successful immunotherapy approaches developed in recent years. Most CAR-T cell therapy has been used clinically to treat hematological malignancies by targeting the B cell-specific antigen, CD19. However, this approach is not without limitations due to toxicities such as by neurotoxicity or cytokine release syndrome. Additionally, CAR-T cells function only as autologous cells due to graft-versus-host disease that would develop if cells were obtained from another person. Therefore, CAR-T cells must be produced on a patient-specific basis. NK cells, on the other hand, function as allogenic cytotoxic effector cells that do not have to be utilized on a patient-specific basis and are proven to be less toxic since they do not cause cytokine release syndrome, neurotoxicity, or graft-versus-host disease. For these reasons, CAR-engineered NK (CAR-NK) cells have increasingly attracted interest as an alternative CAR-cell therapy. However, there exist other unmet challenges. Targeting CAR-based therapies against solid tumors has been challenging due to the lack of truly tumor-specific antigens as most targets are shared by non-malignant cells and can cause toxicity due to “on-target, off-tumor” effects.” A fine-tunable CAR therapy is useful to better identify and target tumors while limiting this toxicity.

Low Energy and Noise Sub-Sampling Phase-Locked Loop

Phase locked loops are widely employed in radio, telecommunications, computers and other electronic applications. They can be used to demodulate a signal, recover a signal from a noisy communication channel, generate a stable frequency at multiples of an input frequency, or distribute precisely timed clock pulses in digital logic circuits such as microprocessors. Researchers at the University of California, Davis have invented a novel, sub-sampling phase-locked, loop (SSPLL) that uses a sub-sampling lock detector (SSLD) to monitor the harmonic selected by the SSPLL. This technology requires lower energy consumption and reduces signal noise.

Apparatus and Methods for Stimulating DNA Repair Using Red Light Therapy

Red light exposure can have phototherapeutic effects on skin cells and other biological cells and tissues affected by UV damage. However, existing methods and devices using red light in DNA phototherapy have not identified the proper duration, intensity, or delivery mechanisms for optimal DNA repair. If the radiant intensity of the red light is too low, then exposure is inadequate and the repair biomarkers are not activated. Conversely, prolonged exposure to excessive electromagnetic radiation only furthers DNA damage. Moreover, in the context of skin treatment, excessive radiant intensity can burn tissue or have carcinogenic side effects. Thus, there is a need for a device and methods of use that provide safe, effective, and targeted red light DNA phototherapy.

System And Method For Binaural Spatial Processing Of Audio Signals

Audio signal processing is the intentional modification of sound signals to create an auditory effect for a listener to alter the perception of the temporal, spatial, pitch and/or volume aspects of the received sound. Audio signal processing can be performed in analog and/or digital domains by audio signal processing systems. For example, analog processing techniques can use circuitry to modify the electrical signals associated with the sound, whereas digital processing techniques can include algorithms to modify the digital representation, e.g., binary code, corresponding to the electrical signals associated with the sound.  Binaural sound recordings are produced by a stereo recording of two microphones inside the ears of a human or a mannequin head. Such recordings include most cues for sound spatialization detected by humans, and thus, they are able to realistically transmit the localization of the recorded sounds, and in effect provide a three dimensional experience of the soundscape for the listener.

Vascularized Tissue Engineering

Tissue engineering and/or regenerative medicine are fields of life science employing both engineering and biological principles to create new tissues and organs and to promote the regeneration of damaged or diseased tissues and organs. Major advances and innovations are being made in the fields of tissue engineering and regenerative medicine and have a huge impact on three-dimensional bioprinting (3D bioprinting) of tissues and organs. 3D bioprinting holds great promise for artificial tissue and organ bioprinting, thereby revolutionizing the field of regenerative medicine. One of the main roadblocks of 3D bioprinting tissues is the lack of efficient techniques to generated vascularized structures. This is critical for grafting applications as limited supply of nutrients and oxygen resulting in premature death of cells.
