Mitochondrial complex II mutated SDHD cell line
The HEK293ΔSDHD cell line expresses a CRISPR/Cas9 mutated nuclear encoded subunit, SDHD, of mitochondrial complex II (succinate dehydrogenase). This cell line has been shown to significantly alter the function of complex II (CII) of the mitochondrial electron transport chain and displays disruptions to SDHD that mimic clinical presentations of...

HEK293ΔNDUFS2 Cell Line
The HEK293ΔNDUFS2 cell line expresses a CRISPR/Cas9 mutated NDUFS2, shown to significantly alter the function of complex I (CI) of the mitochondrial electron transport chain. This NDUFS2 mutant cell line displays disruptions to NDUFS2 that mimic isolated complex I deficiency and can be used as a powerful model of several types of mitochondrial...

Cyclic gamma-Amino Acids and Peptoid Foldamers
Isonipecotic acid provides a stable scaffold with the potential for useful functionalization. Changing the side chains at the β- or γ-positions in the piperidyl ring will tune a peptide towards its biological target or catalytic function. Modifications at these positions is expected to have little effect on the chair conformation adopted...

Enzymatic Biotransformation of Sucrose to Myo-Inositol Via Non-Natural Pathways and Thereof
We constructed in vitro enzymatic pathways that can convert sucrose to myo-inositol and fructose. Myo-inositol is vitamin V8, which has been widely used in the pharmaceutical, drink, food, feed, and cosmetic industries. Without product separation, a mixture of inositol and fructose will be a perfect functional sweetener, which may be directly added...

Biometric Identification and Authentication Using Cardiac Signals
This paper considers signals from the cardiovascular system for possible use in biometric authentication. The signals of particular interest here derive from photoplethysmography (PPG), which refers to the use of illumination-based sensors that are sensitive to volumetric changes as blood travels through the body. Photoplethysmography sensors have been...

Producing Eicosapentaenoic Acid (EPA) from Biodiesel-derived Crude Glycerol
A novel fungal fermentation process has been developed which converts crude glycerol, a major byproduct of the biodiesel industry, into eicosapentaenoic acid (EPA), an important omega-3 highly unsaturated fatty acid. Biodiesel production is rising exponentially which is creating an urgent need to develop new markets for large quantities of crude glycerol....

Universal-Spatial Robotic Tail Mechanism
The Universal-Spatial Robotic Tail (USRT) is a hybrid robotic manipulator that combines an elastic back bone of a continuum robot with a series serial chain of universal joints as the tail structure. These universal joints allow relative yaw and pitch between individual bodies. Individual segments are created by terminating actuation cabling at a given...
