New And Integrated Method For Continuous Auditory Brain Stimulation

Various examples of delivering continuous auditory stimulation of various kinds (sometimes referred to by the term “entrainment”) have been proposed to modulate brainwaves for therapeutic effect. Current methods of delivering continuous auditory stimulation typically present noises (in the form of clicks, tones, pulses) embedded in music. By modulating the user’s existing audial environment to embed continuous auditory sound stimulation, this technology creates a more tolerable and user-friendly experience that enables prolonged therapeutic stimulation for such neurodegenerative disorders as Alzheimer’s, Parkinson’s and Chronic Traumatic Encephalopathy (CTE).

Biosynthetic Production Of L-4-Chlorokynurenine

The non‐proteinogenic amino acid l‐4‐chlorokynurenine (l‐4‐Cl‐Kyn) is a next‐generation, fast‐acting oral prodrug for the treatment of major depressive disorder. Additional studies report that this drug candidate is effective in animal models for the treatment of neuropathic pain, epilepsy, and Huntington's disease.  After active transport across the blood–brain barrier, it is enzymatically converted into the active agent 7‐chlorokynurenic acid, which is a highly selective competitive antagonist of the N‐methyl‐d‐aspartic acid (NMDA) receptor.   Suicide is 2-7x higher in Veterans than non-veterans, and may be related to brain kynurenine pathway (KP) dysregulation and NMDA receptor (NMDAR) hyperactivation.  L-4-Chlorokynurenine (L-4-Cl-Kyn) is a neuropharmaceutical drug candidate that is in development for the treatment of major depressive disorder (Double-Blind, Placebo-Controlled, Phase 2 Trial to Test Efficacy and Safety of AV-101 (L-4-chlorokynurenine) as Adjunct to Current Antidepressant Therapy in Patients With Major Depressive Disorder (the ELEVATE Study)).

Decision Making Spike Time Dependent Plasticity (STDP) Based Neuronal Network Learning

Biologically inspired neural networks are capable of performing sophisticated information processing. Information processing by the brain is multilayered and involves many sequential steps before sensory information can be interpreted and translated into a behavior or action. What makes this cascade powerful is its ability to learn and respond to an ever changing environment based on patterns. Eventually, information gathered from the senses may reach decision centers (such as lateral intra parietal cortex) that govern behavior and are under the influence of reward signals. While a great deal of research has gone into understanding mechanisms of learning at the cellular level, there is still much to discover regarding how learning at the cellular level gives rise to learning on the level of animal behavior. One of the most promising mechanisms of synaptic change for learning is spike time dependent plasticity ("STDP").

Self-Adaptive Architected Materials for Selective Damping of High Amplitude Sounds

Processes For Microfluidic Fabrication

A method is provided to prepare one or more microfluidic channels on a receptive material by applying an image-forming material to a heat sensitive thermoplastic receptive material in a designed pattern and heating the material under conditions that reduce the size of the thermoplastic receptive material by at least about 60%. In an alternative aspect, the microfluidic channels on receptive material are prepared by etching a designed pattern into a heat sensitive thermoplastic material support and then heating the material under conditions that reduce the size of the thermoplastic receptive material by at least about 60%.

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.
