Be Brief: Glow

Changes in pH cause the rhodol dyes to glow differently, offering insight into diseases that affect mitophagy.Fluorescent dyes help scientists see the inner workings of disease. In a new paper by Haiying Liu (Chem), Rudy Luck (Chem) and Thomas Werner (Bio Sci)—along with student researchers—they examine the efficacy of a rhodol-based fluorescent dye.

Diseases like Alzheimer’s and certain kinds of cancers affect the powerhouses of cells — mitochondria. To keep these powerhouses working efficiently, cells remove damaged mitochondria. This process, called mitophagy, is like a cell taking out the trash. In diseased cells, the garbage piles up and the cell’s pH changes. The rhodol dye responds to pH changes and glows brighter.

Luck adds that he considers it a privilege to be able to contribute to Liu’s attempts to find commercially viable probes. The team also acknowledges that the High-Performance Computer system Superior, managed under Director Gowtham, has advanced the research considerably.

Female professional working at her desk with male colleague working at the back.John Durocher (BioSci)Steve Elmer (KIP) PhD student Ian Greenlund, recent graduate Piersan Suriano and Jason Carter published The paper titled “Chronic Standing Desk Use and Arterial Stiffness” in this month’s issue of the Journal of Physical Activity and Health.

The results of the study indicate that using a standing desk for more than 50% of the workday did not effectively reduce arterial stiffness. The study confirms that aerobic fitness reduces arterial stiffness, and that aging increases arterial stiffness. The authors wish to thank faculty and staff members from around campus who participated in this study.

The 2019 41 North Film Festival Returns, Oct. 31–Nov. 3

41 North LogoThe annual 41 North Film Festival will be held Oct. 31 to Nov. 3 at the Rozsa Center for the Performing Arts. This year’s program features more than 20 films from around the world, along with music, events and special guests Anishinaabe filmmaker/producer Michelle Derosier and Michigan Tech alumnus actor/writer/producer Curtis Fortier.

This year’s highlights include:

  • Thursday, Oct. 31, 7:30 p.m.: HUMAN NATURE, which delves into the complexities of editing the human genome. Followed by a Q&A with Caryn Heldt (ChE), Paul Goetsch (BioSci) and Alexandra Morrison (HU).
  • Friday, Nov. 1, 7:30 p.m.: PICTURE CHARACTER (an Emoji Documentary). This informative and entertaining film covers everything from how emojis came into existence to how new emojis are added to the unicode system. To add to the fun, come in an emoji-inspired costume and you might win a prize. Stick around after the film for emoji cookie decorating and music in the lobby.
  • Saturday, Nov. 2, will feature a full day of programming about our relationship to the environment. Films include ANTHROPOCENE: THE HUMAN EPOCH, THE BIGGEST LITTLE FARM, HONEYLAND, and our featured presentation of Michelle Derosier and her film ANGELIQUE’S ISLE, inspired by the true story of Angelique Mott, an Anishinaabe woman who, with her husband, was abandoned by unscrupulous copper miners and left to die during the winter of 1845 on an island off of Isle Royale (today known as Mott Island).
  • Sunday, Nov. 3. Michigan Tech alumnus Curtis Fortier will be on hand to present and discuss some of his work as an actor/writer/producer. Fortier will be followed by a new docudrama about the life of information theorist Claude Shannon, THE BIT PLAYER. The festival will close Sunday evening with MAIDEN, the thrilling and emotional story of the first all-female crew to compete in the Whitbread Round-the-World Yacht Race.

See the full line-up of films and events at 41northfilmfest.org. The festival is free and open to the public. Students will need to bring their HuskyCard. Tickets for everyone else can be reserved at tickets.mtu.edu or by calling 7-2073. They will also be available in the Rozsa lobby prior to each film.

6th Annual Michigan Physiological Society Meeting

Ten graduate students, seven undergraduate students, four faculty members, and two recent alumni from Michigan Tech recently participated in the 6th annual Michigan Physiological Society Meeting held on the campus of Central Michigan University on June 27-28.

John Durocher (BIO) served as the president of the society and Ian Greenlund (KIP) served as the trainee committee chair. Four MTU graduate students completed oral presentations, with Jeremy Bigalke (KIP) winning one of the top oral presentation awards.

Another thirteen MTU students were active in poster presentations, with Sarah LewAllen (BIO) winning one of the top poster presentation awards. Finally, two graduate students served as moderators for oral presentations.
In conjunction with the annual meeting, the 3rd annual Michigan Physiology Quiz competition was held. Michigan Tech competed against six other teams from around the state. Team members included Jana Hendrickson (KIP), Sarah LewAllen (BIO), Jill Poliskey (BIO), and Colleen Toorongian (KIP).

The Michigan Tech team was very competitive through four rounds but missed making the final round between the top three teams by a single question. All team members did a great job with the intense questions.

Michigan Tech was one of only three universities from around the state to achieve Diamond-Level Sponsorship! This was possible thanks to the College of Sciences and Arts, Michigan Tech Graduate School, Department of Biomedical Engineering, Department of Kinesiology and Integrative Physiology, and Department of Biological Sciences. Additional faculty and staff members from Michigan Tech also made individual awards that contributed to the cash prizes for the quiz competition, oral presentations, and poster presentations.

Local Students Win Portage Health Foundation Making a Difference Scholarships to Michigan Tech

1491240303Four students who are entering Michigan Tech this fall to pursue health-related careers have received $8,000 Making a Difference scholarships from the Portage Health Foundation. Another 10 entering first-year students received $1,000 awards.

The $8,000 scholarships went to:

  • Peter Alger, Houghton, computer engineering
  • Alexa Destrampe, Lake Linden, exercise science
  • Hannah Kariniemi, Calumet, biological sciences
  • Karmyn Polakowski, Houghton, biological sciences

Receiving $1,000 scholarships were:

  • Blake Dupuis, Lake Linden, exercise science
  • Lauren Gabe, L’Anse, biological sciences
  • Austin Goudge, Houghton, medical laboratory science
  • Bella Nutini, Hancock, exercise science

  • Sloane Zenner, Houghton, mechanical engineering

The students are from Houghton, Keweenaw, Baraga or Ontonagon counties.

The 14 recipients of the 2017 awards have an average GPA of 3.81. Their interests reflect a broad spectrum of majors including biological sciences, exercise science, biomedical engineering, computer engineering, medical laboratory science and mechanical engineering. The scholarship winners flip Michigan Tech’s male to female ratio of 3:1, with 10 female and 4 male recipients.

The scholarships are part of a Michigan Tech-Portage Health Foundation partnership established in 2015 to support health-related research and education, jobs and community health. The scholarships were first awarded in 2016.

“The awards reflect the high-caliber student talent we have locally, thanks to exceptional schools, outreach programming and parent support,” says Jodi Lehman, director of foundations at Michigan Tech. “We know that student talent is key in supporting the success of college peers and inspiring K-12 students to pursue health science and engineering pathways.

The Portage Health Foundation and Michigan Tech share the long-term goal of retaining or recruiting back local workforce talent — whether that be orthodontists, doctors, physical therapists, orthopedic surgeons, biomedical engineers or professionals in the field of medical informatics. Scholarships ultimately play a critical role in helping to grow our local economy while fostering healthy communities.”

At a dinner for finalists, the scholarship recipients heard from current students also supported by the Portage Health Foundation through the Undergraduate Research Internship Program (URIP). Both speakers shared their internship experiences and career goals.
