New Inventions

New Hormone Analogs for Treating Hypoparathyroidism

UW–Madison researchers have developed backbone-modified analogs of PTH(1-34). The analogs exhibit advantageous properties; they are biased toward Gs activation/cAMP production relative to β arrestin recruitment.

The analogs were generated via an unconventional strategy in which the backbone of a natural PTHR-1 agonist was altered, rather than the side-chain complement. More specifically, selected α-amino acid residues were systemically replaced with either β-amino acid residues or with unnatural D-stereoisomer α-amino acid residues.

The researchers have shown that backbone-modification can rapidly identify potent agonists with divergent receptor-state selectivity patterns relative to a prototype peptide.

Industrial Furnace With Flameless Combustion and Impingement Flow for Increased Efficiency, Reduced Emissions and Intensified Heat Transfer

An assistant professor of mechanical engineering technology and inventor from the University of Wisconsin Oshkosh has developed an industrial natural gas furnace and oven design that combines flameless combustion with high velocity impingement gas and air jets directed toward the product being heated. This novel combination has the potential to provide advantages over conventional technology that include higher energy efficiency, uniform temperature distribution, reduced NOx emissions, and intensified convection heat transfer. The design also has the potential to increase productivity by allowing more material to be processed within the same combustion area. This innovative system can be used for production of new furnaces as well as retrofitting existing installations.

Soybeans with Increased Resistance to Sclerotinia Stem Rot and Drought Tolerance

UW–Madison researchers have demonstrated that knocking down expression of a specific soybean respiratory burst oxidase homolog protein (GmRBOH-VI) leads to enhanced resistance to S. sclerotiorum and confers drought tolerance.

Using protein sequence similarity searches, the researchers identified seventeen GmRBOHs and studied their contribution to Sclerotinia disease development, drought tolerance and nodulation. Transcript analysis of all seventeen GmRBOHs revealed that out of the six identified groups, group VI (GmRBOH-VI) was specifically and drastically induced following S. sclerotiorum challenge. Virus-induced gene silencing of GMRBOH-VI resulted in enhanced resistance to the fungus and, coincidently, drought stress.

Based on these discoveries, the researchers have developed modified soybeans and production methods available for licensing.

Modified Newton’s Cradle Demonstrating Mechanical Impedance

A Physics professor and inventor at the University of Wisconsin – Whitewater has developed a modified Newton’s Cradle that allows the user to visualize and test the concept of mechanical impedance in addition to momentum and energy conservation. The traditional version of Newton’s cradle has a cradle of identical metal spheres. In this modified and improved device, the user is able to interchange these spheres with ones of varying mass and material composition. By allowing the user to strategically align and create a unique cradle, they have the opportunity to visualize mechanical impedance. For example, a sphere with a small mass would have the ability to strike the cradle and lift a sphere of greater mass on the opposite side if the spheres in-between had a gradient of increasing mass themselves. The possibility of changing a sphere at any position in the cradle allows for an exceptionally large number of possible experiments and would overall lead to an enhanced understanding of the aforementioned physics concepts, something a traditional cradle device does not provide for.

Novel Transparent Dilatant Materials Comprised of Single Chemical Component

Research from the University of Wisconsin-Stevens Point has resulted in the synthesis of a series of materials exhibiting a range of dilatant properties. The materials show good transparency and are chemically uniform (e.g. consisting of a single chemical component). The degree of dilatancy is easily controlled by adjusting the compositions of the materials. Due to the range of dilatant properties, good transparency, and single chemical component nature of the dilatant samples, these materials show significant promise for novel uses in protective equipment and other areas related to impact protection, especially where transparency is desirable.

Bio-Based Production of Non-Straight-Chain and Oxygenated Fatty Acids for Fuels and More

UW–Madison researchers have identified several enzymes in the bacterium Rhodobacter sphaeroides that can be purified to produce non-straight-chain fatty acids in vitro or expressed in genetically modified microorganisms including E. coli for synthesis in vivo. Strains may be ‘fine-tuned’ to produce a specific type of non-straight-chain fatty acid (e.g., furan-containing) by expressing, overexpressing or deleting the enzymes in various combinations.

“Green” Triboelectric Power Boards Turn Footsteps into Electricity and More

UW–Madison researchers have developed the first TENG device built entirely from biodegradable and green materials. The two active layers comprise cellulose nanofibrils (CNFs) or wood fibers chemically treated to alter their electron affinity. CNFs and wood fibers are ideal because they have high surface areas, can be functionalized with a variety of chemical groups and can be formed into flexible and optically transparent films.

Enhancing Cell Penetration to Improve Drug Delivery

UW–Madison researchers have developed a method for enhancing cellular uptake of a cargo molecule by covalently bonding fluorenyl groups to it. The fluorenylated molecule is then contacted with the cell or tissue. Cellular uptake may be in vivo or in vitro and includes at least partial penetration into the cytosol.
