Nylon-3 Polymers to Treat Fungal Infections

UW–Madison researchers have found that nylon-3 polymers developed in their lab display potent antifungal activity against a broad spectrum of common fungal pathogens, with minimal toxicity towards mammalian cells. The polymers have some activity alone, and when used in combination with existing drugs provide synergistic effects against Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus strains, including some resistant strains.

Synergistic combination offers efficacy with significantly reduced amounts of drug and corresponding toxicity, which could potentially expand the relevant patient population.

The polymers were designed to resemble host-defense peptides (HDPs), which are natural molecules that exhibit antimicrobial activities.

Analogs of Diptoindonesin G for Breast Cancer Drug Development

UW–Madison researchers have synthesized analogs of Dip G that have shown a greater ability than the parent molecule to decrease ERα expression and stabilize ERβ in cultured breast cancer cells. The compounds are active for ameliorating, attenuating and halting the growth/metastasis of breast cancers.

Physics ‘Office Hours’ educational learning platform

A physics education researcher at the University of Wisconsin-Green Bay has designed a novel and interactive app-based study aid platform for students in STEM disciplines. The platform’s interface is built around education research into how students conceptualize problems they do not understand. It is a novel tool to help students see why they are struggling with a particular problem, and what might help them solve it, rather than solving the problem for them. The team’s first working prototype, the Physics Office Hours app, has been designed for use in introductory-level college physics. The app is designed to mimic a scenario students might face during ‘office hours’ with a professor: Rather than offering an answer, the instructor guides the students through problems via a series of questions. A user-friendly online interface allows app content to be easily updated and changed over time and as more problem sets become available. In addition, the app architecture can easily be adapted to problem sets in other STEM disciplines and therefore serves as a platform technology.

Efficient In Vitro Assay for Antigen-Specific Tolerance

Building on their work, UW–Madison researchers have now developed a T cell-bound cytokine (T-CBC) assay for detecting and quantifying regulatory T cells specific to self-antigens or donor alloantigens. The new method comprises (a) culturing the subject’s T cells for 24 hours in the presence of one or more target antigens and (b) analyzing the cultured T cells for expression of a marker (EBi3; TGFβ/LAP) indicative of antigen-specific immune suppression.

Genetic Testing for Acquired Peripheral Neuropathy in Dogs

UW–Madison researchers have identified a single nucleotide polymorphism (SNP) that is predictive of APN syndrome in dogs, based on a genome-wide association study. Using a population of Labrador retrievers (56 cases and 26 controls), the researchers have shown that a SNP on CFA1 tags the causal variant for APN in the Labrador retriever breed.

Optimizing Nitrogen Use Efficiency in Dairy Cattle

A UW–Madison researcher has developed a simple algorithm to optimize nitrogen use efficiency based on values already measured in most dairy herds: milk urea-nitrogen yield (MUNY) and protein yield (PY) in milk. Once an ideal MUNY/PY ratio is identified through careful measurement, the value can be constantly monitored to determine if feed practices need to be adjusted. This kind of feedback can be provided within a day, unlike any other method.

Tactile Button Panel for Use with Touch Screens

UW–Madison researchers have developed a touch screen system that attaches a simple button fixture over a portion of the screen. This is important because virtual ‘buttons’ may be difficult to see or manipulate.

The buttons have clear markings that can be felt by a user. When pressed, the buttons contact the touch screen and the task is performed as usual. The button panel may be mounted permanently or fastened.

More Accurate Branch Predictor Circuit

UW–Madison researchers have developed a more accurate branch prediction method by distinguishing between ‘biased’ and ‘non-biased’ branch instructions. Biased branches are consistently skewed towards one direction while non-biased branches resolve in both directions.

The new method filters out biased branches because they merely reinforce earlier prediction decisions. Favoring non-biased branches enables more far apart correlations and superior prediction accuracy.
