Notre Dame research finding may help accelerate diabetic wound healing

Author: William G. Gilroy

Mobashery Lab

University of Notre Dame researchers have, for the first time, identified the enzymes that are detrimental to diabetic wound healing and those that are beneficial to repair the wound.

There are currently no therapeutics for diabetic wound healing. The current standard of care is palliative to keep the wound clean and free of infection. In the United States, 66,000 diabetic individuals each year undergo lower-limb amputations due to wounds that failed to heal.

Gary Lamberti

Illinois-Indiana Sea Grant has announced more than $300,000 in funding awards for three research projects over the next two years. Funded projects seek to improve understanding of the Lake Michigan near shore food web, uncover connections between sediment removal projects and a community’s ability to weather environmental hazards, and identify why people adopt storm water management practices.

Notre Dame researchers look at benefits of flu vaccines in the elderly

Author: Sarah Craig

Benjamin Ridenhour

New research at the University of Notre Dame looks more closely at the effects of the influenza vaccine on the elderly, who are considered the highest-risk group for influenza-related mortality.

Despite the fact that the elderly are more susceptible to falling ill, very little is known about how well the influenza vaccination performs for those older than 65 years of age

A new way to counter ovarian cancer’s drug resistance

Author: Michael Rodio

Ovarian cancer cells

Standing at a microscope in her Harper Hall laboratory, Dr. Karen Cowden Dahl is scanning through a petri dish filled with cancer cells that could represent a major step forward in ovarian cancer research.

Ovarian cancer is especially cruel because it is so hard to detect. While other types of cancer like breast cancer have reliable indicators that allow for early detection, ovarian cancer is hard to catch in its early stages.

But Cowden Dahl has found a biological marker that could be the long sought-after warning flag for ovarian cancer: ARID3B, a ubiquitous but poorly-understood transcription factor gene that acts like a switchboard operator by turning genes on and off in normal cells.

Notre Dame network physicist describes network model of brain’s connectivity

Author: Stephanie Healey

 

Zoltan Toroczkai

A new paper by Zoltán Toroczkai, professor of physics and concurrent professor of computer science and engineering at the University of Notre Dame, and his collaborators provides a predictive model of cerebral cortical connectivity at the interareal level. The study was published in the Oct. 2 issue of the journal Neuron.

The cerebral cortex is responsible for all the sensory, motor and cognitive functions of an individual and is arguably the most powerful known supercomputer.

Notre Dame physicists celebrate announcement of Nobel Prize for Higgs discovery

Author: Marissa Gebhard

Higgs boson

At 6:45 a.m. Tuesday (Oct. 8), the Royal Swedish Academy of Sciences awarded the Nobel Prize in physics to theorists Peter Higgs and Francois Englert to recognize their work developing the theory of what is now known as the Higgs field, which gives elementary particles mass. U.S. scientists played a significant role in advancing the theory and in discovering the particle that proves the existence of the Higgs field, the Higgs boson.

Colin Jessop, professor of physics at the University of Notre Dame, is the leader of the Notre Dame team that works on the Compact Muon Solenoid (CMS) collaboration at CERN. The team’s experiment is one of two Large Hadron Collider (LHC) experiments that shared the Higgs boson discovery.

Prashant Kamat presents work on low-cost solar cell alternatives

Author: Shadia Ajam

Prashant Kamat

Recently Prashant V. Kamat, The Rev. John A. Zahm C.S. C Professor of Science, gave a presentation on low-cost solar-cell alternatives at the annual American Chemical Society meeting in Indianapolis.

Scientists have been searching for ways to make low-cost solar cells, photovoltaic devices that convert light to electricity. Solar-cell technology isn’t new, but the high cost of producing the technology makes it difficult for wide use.

Kamat’s research has focused around quantum dots, an approach that takes advantage of the ease of making, tuning, and processing light-absorbing nanocrystals of semiconductors with colloidal chemical methods.

Notre Dame researchers make progress toward a treatment for dangerous allergies

Author: Arnie Phifer

nut_warning_1

New research published in the journal Nature Chemical Biology shows that a group of scientists, led by faculty at the University of Notre Dame, has made concrete progress toward the development of the first-ever inhibitory therapeutic for type-I hypersensitive allergic reactions.

“Our allergy inhibition project is innovative and significant because we brought a novel molecular design approach to selectively inhibit ‘mast cell degranulation’–the key event in triggering a food allergic response–which has the potential to improve the quality of life for affected patients,” explains Basar Bilgicer, Assistant Professor of Chemical and Biomolecular Engineering at Notre Dame and an investigator in the university’s Advanced Diagnostics & Therapeutics initiative

Notre Dame researchers uncover keys to antibiotic resistance in MRSA

Author: Marissa Gebhard

MRSA

University of Notre Dame researchers Shahriar Mobashery, Mayland Chang, their team members, and their collaborators in Spain have published research results this week that show how methicillin-resistant Staphylococcus aureus (MRSA) regulates the critical crosslinking of its cell wall in the face of beta-lactam antibiotics.

The work, published in the Proceedings of the National Academy of Sciences, reveals the mechanistic basis for how the MRSA bacterium became such a difficult pathogen over the previous 50 years, in which time it spread rapidly across the world.
