Effective Repetitive Transcranial Magnetic Stimulation (rTMS) Taking in Account Real-Time Frequency and Phase Of Intrinsic Brain Activity

Current research and practice in the field of therapeutic rTMS is not taking into account 1) inter-individual variability 2) variability between brain areas 3) variability or differences between oscillations in distinct and overlapping frequency bands, 4) existence of high- and low-excitability phase periods in each oscillatory cycle. Clinical treatments with rTMS and experimental research findings show mixed effects, with rTMS protocols inducing variable degrees of brain plasticity over subjects and sessions.

Stamping-based Method for Microwell Production and Cell Aggregate Formation

Researchers at the University of California, Davis have developed a 3-D printed stamping system (the “Aggrestamp”) with the capability for in-situ production of microwells that facilitate cell aggregate formation.

Automated Drosophila Maintenance System

Drosophila spp., also known as fruit flies, are widely used in genetic research. Drosophila lines (e.g. flies with a particular mutation) can only be stored as live animals – they cannot be frozen and remain viable. So to maintain the stocks, the live flies are manually transferred from an old vial to a new vial on a regular basis (every 1-2 weeks). Some Drosophila labs maintain hundreds or even thousands of individual lines and so maintenance of these lines can be very time consuming. A UC Santa Cruz Drosophila researcher has developed a simpler and more efficient method of transferring the flies that requires significantly less hands-on work.

Crosslinkable Polymer Coating Prevents Bacterial Infection on Implant Surface

UCLA researchers in the Department of Orthopedic Surgery have developed a polymer implant coating that mitigates bacterial infections on the implant surface.

Reactive Oxygen Species (ROS) Resistant Platform Strains for Bioproduction

The survival of bacteria is associated with the ability to respond to changing environmental conditions. For example, during situations of environmental pressure (e.g. UV, heat, or drug exposure) ROS levels can increase, leading to damage of DNA, lipids and an initiation of signaling events that can lead to cell death. Fortunately, bacterial possess enzymes such as superoxide dismutase (SOD) and catalase enzymes, as well as other antioxidant agents that can reduce ROS. However, when the balance between the production and elimination of ROS is upset, it can have unwanted effects. Thus, the ability of bacteria to increase their tolerance to ROS would be beneficial to the cell’s survival.

Identification of a New Molecular Target and Methods for Treating Pancreatic Cancer

Pancreatic cancer is an aggressive disease with limited treatment options and a high mortality rate. Pancreatic cancer is the 3rd leading cause of cancer death in the United States; despite some recent advances in systemic therapy, survival remains dismal in large part due to its profound drug resistance and its propensity for early metastasis. Typically, diagnosis of pancreatic cancer occurs only with advanced stages of the disease since there are currently no early markers for detection. Individuals with pancreatic cancer have a poor prognosis due to the late diagnosis, the extent of metastasis, and ineffective treatments. Survival rates are dismal, with a one-year survival rate of 25% and a 5-year survival rate of 6%. Currently, approximately 20% of pancreatic cancer patients are able to undergo the Whipple procedure; this surgical procedure involves removal of the affected portion of the pancreas, leading to an increased survival rate. However, the remaining 80% of pancreatic cancer patients cannot undergo this treatment because their tumors or the extent of metastasis are too severe. In addition, pancreatic cancer is not typically responsive to radiation and chemotherapy. An alternative approach for the treatment of pancreatic cancer is a complete pancreatectomy followed by continual supplementation with digestive enzymes and insulin. Thus, more effective drugs are needed to increase the survival rate of pancreatic cancer patients. Targeting RORγ may lead to the design of a new class of therapeutics that can be used to treat this devastating disease.

The CryoEM Method MicroED as a Powerful Tool for Small Molecule Structure Determination

UCLA researchers in the Department of Chemistry and Biochemistry have developed a novel use of the cryogenic electron microscopy (CryoEM) method electron micro-diffraction (MicroED) to provide routine and unambiguous structural determination of small organic molecules.

Head-Mounted Display EEG Device

Diagnosis and detection of progression of neurological disorders remain challenging tasks. For example, a validated portable objective method for assessment of degenerative diseases would have numerous advantages compared to currently existing methods to assess functional loss in the disease. An objective EEG-based test would remove the subjectivity and decision-making involved when performing perimetry, potentially improving reliability of the test. A portable and objective test could be done quickly at home under unconstrained situations, decreasing the required number of office visits and the economic burden of the disease. In addition, a much larger number of tests could be obtained over time. This would greatly enhance the ability of separating true deterioration from measurement variability, potentially allowing more accurate and earlier detection of progression. In addition, more precise estimates of rates of progression could be obtained.

Array Atomic Force Microscopy Enabling Simultaneous Multi-point and Multi-modal Nanoscale Analyses

Nanoscale multipoint structure-function analysis is essential for deciphering the complexity of multiscale physical and biological systems. Atomic force microscopy (AFM) allows nanoscale structure-function imaging in various operating environments and can be integrated seamlessly with disparate probe-based sensing and manipulation technologies. However, conventional AFMs only permit sequential single-point analysis. Widespread adoption of array AFMs for simultaneous multi-point study is still challenging due to the intrinsic limitations of existing technological approaches.

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.

Carborane-Based Histone Deacetylase (HDAC) Inhibitors

Source Tracking Though Spectral Matching To Mass Spec Databases

Modern metabolomics, proteomics and natural product datasets have now reached into the millions of tandem mass (MS/MS) spectra. The rapidly growing size of these datasets precludes laborious manual data interpretation of all of the data. While MS/MS spectral library search approaches match spectra in an automated fashion, the limited size of available spectral libraries limits identification rates of datasets to single digit percentages. In addition, the sharing of experimental MS/MS data between researchers is not that common. What is needed is a way to organize both identified and unidentified spectra into structurally related molecular families that is searchable.

Methods To Biosynthesize Kainic Acid And Analogues Thereof

Kainic acid is a chemical first derived from seaweed. Neuroscientists routinely use Kainic acid to simulate brain degeneration in lab experiments. Certain inotropic receptors in the brain--known as kainate receptors--are selectively activated only by kainic acid. Research into kainate receptors helps researchers to understand Alzheimer's disease, epilepsy, and other brain disorders. Some scientists use kainic acid to find answers to more fundamental questions such as the function of glutamate receptors. Currently, there are two procedures for generating kainic acid commercially. The first involves the farming and collection of kainic acid-containing seaweed and that method is impacted by seasonal fluctuations of seaweed growth and kainic acid production. The second involves synthetic processes, but the current procedures generally require at least 6 synthetic steps with yields less than 40% and generate environmentally toxic byproducts including heavy metals, cyanides, or halogenated organics.

Flavonol Profile as a Sun Exposure Assessor for Grapes

Method to Reuse Multielectrode Arrays in Rodents

Researchers at the University of California have developed a protocol to enable the reuse of MEA probes.  Using this protocol, the MEA probes can be carefully peeled off undamaged from a protective layer, cleaned with ethanol and stored for re-use.  In addition, at each reuse the measured electrode impedances remain within the normal range set by the manufacturer for every channel and the probes may be reused up to six times.  This protocol is an improvement over the existing published protocols in that (1) these particular MEA electrodes are available commercially in a variety of configurations; (2) the MEA can be reused a number of times in order to record EEG in freely moving mice. Fig. 2 Setup of MEA EEG that allowed for enhanced reusability.
