Global Health Initiatives: Dr. Fiona Strasserking's Impact on Cardiovascular Care in Zambia – Archyde

Nov 4, 2024 | archyde.com | Christen Brownlee

By Christen BrownleeDALLAS – Nov. 04, 2024 – On a typical Thursday morning in Dallas, Fiona Strasserking, M.D., engages in a thoughtful exchange with her UT Southwestern colleague. Meanwhile, internal medicine residents from the University of Zambia prepare to join their virtual training session via Zoom. Today’s featured lecturer is Rafic Berbarie, M.D., an Associate Professor in UTSW’s Division of Cardiology.
Out of Africa: UT Southwestern cardiologist gets to the heart of Zambia’s No. 1 health threat

By Christen Brownlee DALLAS – Nov. 04, 2024 – On a Thursday morning in Dallas, Fiona Strasserking, M.D., chats with her UT Southwestern colleague while internal medicine residents from the University of Zambia log on to their Zoom call. Rafic Berbarie, M.D., Associate Professor in UTSW’s Division of Cardiology, is today’s guest lecturer and the topic is “Evaluation of Chest Pain.” He’ll cover everything from chronic angina to myocardial infarction.
Magnetic ‘rusty’ nanoparticles pull estrogen out of water

Aug 16, 2023 | sciencenews.org | Skyler Ware |Christen Brownlee |Soumya Sagar |McKenzie Prillaman

A new “smart rust” could one day help pull pollutants out of waterways, leaving cleaner water behind. Researchers adorned tiny particles of iron oxide, better known as rust, with “sticky” molecules that grab on to estrogen and similar hormones in water samples. A magnet can then remove both the particles and the trapped pollutants from the water, materials scientist Lukas Müller reports August 16 in San Francisco at a meeting of the American Chemical Society.
Readers react to a revamped insecticide and a chronic pain biomarker

Aug 11, 2023 | sciencenews.org | Christen Brownlee

Microwaving deltamethrin can renew the insecticide’s ability to kill mosquitoes that have become resistant to it. Scientists are working to add the improved insecticide to bed nets, Tina Hesman Saey reported in “Restoring an insecticide’s mosquito-killing power” (SN: 6/17/23, p. 4).
The thymus withers away after puberty. But it may be important for adults

Aug 2, 2023 | sciencenews.org | McKenzie Prillaman |Christen Brownlee

A mysterious organ that’s most active in childhood might play a previously underappreciated role in adults. In a study of almost 2,300 adults who underwent chest surgery, removing the thymus gland was associated with higher rates of death and of cancer within the next few years, researchers report in the Aug. 3 New England Journal of Medicine. The discovery pushes back on a long-held belief that the immune system organ is somewhat expendable in adulthood.
Human embryo replicas have gotten more complex. Here’s what you need to know

Jul 24, 2023 | sciencenews.org | Tina Saey |Christen Brownlee |Aina Abell

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — masses of cells created from stem cells that mimic some properties of certain stages of embryo development. The achievement gives researchers a chance to look at human development beyond the first week or so, when an embryo must implant in the uterus to develop further.
Air pollution monitoring may accidentally help scientists track biodiversity

Jun 5, 2023 | sciencenews.org | Christen Brownlee

The ability to track animals and plants is up in the air — literally — thanks to help from an unexpected source. Around the globe, many air quality control stations filter air through small paper disks on a daily or weekly basis, allowing scientists to ensure concentrations of hazardous pollutants such as heavy metals are below certain levels. But the filters also pick up plant and animal DNA that has been scattered into the wind, researchers report June 5 in Current Biology.

Study in mice suggests that oxygen restriction could extend life span by CHRISTEN BROWNLEE May 23, 2023 Research 4 min read Image: Koonyongyut/iStock/Getty Images Plus At a glance:Living in a low-oxygen environment extended life spans, preserved neurologic function in mice. Findings add to a growing body of research showing oxygen restriction may ward off neurologic decline and extend life span in animal models.
