Malinauskas attends Oxford Nanopore Technologies Community Meeting

"The [meeting] was a tremendous opportunity for me to network and learn from other scientists in my field," said JENNA MALINAUSKAS (IDM). "I learned tips and tricks to sequencing during the hands on training portion, what resources are available to me as a researcher, and how to improve my science. The opportunity to become more involved in the scientific community will benefit me throughout my career and I'm excited to attend more conferences i... 

Widespread virus replication in alveoli drives acute respiratory distress syndrome in aerosolized H5N1 influenza infection of macaques

JOURNAL OF IMMUNOLOGY - Wonderlich, Swan, Bissel, Hartman, Carney, O'Malley, Obadan, Santos, Walker, Sturgeon, Frye, Maiello, Scanga, Bowling, Duangkhae, Wiley, Flynn, Wang, Cole, Reed, Barratt-Boyes establish a new nonhuman primate disease model for evaluation of vaccine and therapeutic approaches to prevent and treat infection with highly pathogenic avian influenza viruses.   

Novel assay reveals a large inducible replication competent HIV-1 reservoir in resting CD4+ T cells

NATURE MEDICINE - Gupta, Sanyal, Ratner, Ding, Zerbato, Giacobbi, Venkatachari, Patterson, Chargin, Chen, Mailliard, Rinaldo, and Sluis-Cremer found that the size of the inducible latent HIV-1 reservoir in aviremic subjects on ART is approximately 70-fold larger than previous estimates.   

Peripheral blood biomarkers of disease outcome in a monkey model of rift valley fever encephalitis.

JOURNAL OF VIROLOGY - Wonderlich, Caroline, McMillen, Walters, Reed, Barratt-Boyes, and Hartman conclude that African green monkeys are a novel and suitable model for studying the neuropathogenesis of Rift Valley Fever (RVF) and for testing vaccines and therapeutics against this important emerging viral disease for which we lack both an effective human vaccine and treatment. Encephalitis and neurological disease resulting from RVF lead to death ... 

Amid opioid crisis, Frank addresses Titusville community

TITUSVILLE HERALD - Community members and students from Pitt's Titusville campus gathered to hear IDM's LINDA FRANK discuss drug misuse versus drug abuse, the opioid epidemic's relation to to the spread of HIV/AIDS and Hepatitis C, available prevention and treatment strategies, and the implications for health professionals, families, community members, and local organizations.   

Chuan, Sabnis, and Salerno are recipients of 2017 Bob Yee Student Award

Congratulations to IDM students BYRON CHUAN, SANIYA SABNIS, and JESSICA SALERNO for receiving the Bob Yee Student Award, given to incoming students showing previous academic merit.   

De Ferrari and Lancaster receive the Russell Rule Rycheck Award

Professor Russel Rule Rycheck was an epidemiologist who was devoted to teaching and mentoring students. He believed that public health professionals must have a “professional bag” full of tools and skills needed to make an impact on the public’s health. This award enables MPH students to develop further skills and competencies for the professional bag. This year's winners include ROSA DE FERRARI (BCHS) and ASHYLN LANCASTER (IDM).   

Lancaster and Ma receive Owen's Fellowship

ASHLYN LANCASTER and HENRY MA, both IDM students, received the Owen's Fellowship from the University. A bequest of Samuel T. Owens Jr. makes fellowships available for students who show promise of high academic achievement.    

As Zika babies become toddlers, some can’t see, walk, or talk

image
NEW YORK TIMES - Infectious disease researcher ERNESTO MARQUES says about 3 percent of 1,000 pregnant Brazilian women in a recent sample were infected with Zika. “The problem’s not going away. We are still having cases. And the future of Zika babies already born is complicated by poverty and strained resources. “Most of these babies are from low socioeconomic status and rely on the public health system to provide care. It’s very difficult to mana... 

Mailliard presents research on improving HIV “kick and kill” strategies to IAS Conference on HIV Science in Paris (Video)

image
YOUTUBE - IDM's Mailliard presents his research on “kick and kill” strategies at the 9th IAS Conference on HIV Science, the world's largest open scientific conference on HIV and AIDS-related issues. The work demonstrates that naïve T cells have the ability to effectively target the HIV-1 reservoir, highlighting the importance of directing HIV-1 curative strategies towards the induction of de novo rather than memory HIV-1-specific CTL responses.
