(Press-News.org) Which medicine is best when you are affected by cancer? This can vary from person to person. A new method can help people with a specific type of blood cancer get the best medicine for them.
“The new method can help those affected by chronic myelogenous leukemia,” says Jennifer Sheehan, a PhD research fellow from the Department of Mechanical Engineering and Production at the Norwegian University of Science and Technology (NTNU). Sheehan was first author of a new publication in PLOS Computational Biology that describes the method.
The research is a collaboration between NTNU, Linnaeus University in Sweden and the Universidade de São Paulo.
Blood cancer can develop insidiously
Chronic myelogenous leukemia, or CML, is a relatively rare variant of blood cancer. In Norway, around 70 people are affected per year.
The disease seems to be caused by a piece of one chromosome breaking off and attaching to another. This creates an abnormal gene that causes immature white blood cells to spread rapidly and fill the blood vessels. In other words, the patient gets cancer.
“CML is a form of cancer that many people live with for a long time without knowing it. Symptoms can be absent for several years before the patient becomes visibly ill," says Astrid S. de Wijn, a professor at NTNU's Department of Mechanical Engineering and Production, and Sheehan's supervisor.
Finding the right medicine for CML
Today, the most effective form of treatment is stem cell transplantation. Many can avoid transplantation if they receive effective help with medication instead. The vast majority of people can manage without it, as long as they receive effective medications called thyrokinase inhibitors. But there are five different medications for CML, and it is important to find the one that is most effective.
The medications attack an enzyme. Enzymes are substances that are needed to start or keep various processes in the body going. The goal of the medications is to slow down the problematic overproduction of cells in the blood.
However, mutations, which are spontaneous changes in the cells, can cause the medications to lose all or part of their effect against blood cancer.
“We have developed a computer model that can help us say which drugs work best, and thus are best suited for each individual patient,” says Professor Ran Friedman at Linnaeus University.

Expanded research on COPD and metabolic syndrome would advance patient-centered care
2025-01-09
Miami (January 9, 2025) – Additional research addressing the connection between chronic obstructive pulmonary disease (COPD) and metabolic syndrome is needed to improve holistic patient care, according to a new editorial. The editorial is published in the November 2024 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open-access journal.
COPD is an inflammatory lung disease, comprising several conditions, including chronic bronchitis and emphysema, and can be caused by genetics and irritants like smoke ...
Mount Sinai-led team enhances automated method to detect common sleep disorder affecting millions
2025-01-09
A Mount Sinai-led team of researchers has enhanced an artificial intelligence (AI)-powered algorithm to analyze video recordings of clinical sleep tests, ultimately improving accurate diagnosis of a common sleep disorder affecting more than 80 million people worldwide. The study findings were published in the journal Annals of Neurology on January 9.
REM sleep behavior disorder (RBD) is a sleep condition that causes abnormal movements, or the physical acting out of dreams, during the rapid eye movement (REM) phase of sleep. RBD that occurs in otherwise healthy adults ...

Bridging oceans: A US-Japan approach to flood risk and climate resilience
2025-01-09
An innovative project jointly funded by the United States National Science Foundation (NSF) and the Japan Science and Technology Agency (JST) brings together a team of scientists from Florida Atlantic University and Lehigh University, along with a team from Japan that includes researchers from Kyoto University, University of Tokyo and Kumamoto University.
The project, titled “NSF-JST: An Inclusive Human-Centered Risk Management Modeling Framework for Flood Resilience,” is supported by a three-year, $1 million award split evenly between the U.S. and Japanese teams, with the U.S. team receiving $499,271. ...
Dense human population is linked to longer urban coyote survival
2025-01-09
COLUMBUS, Ohio – Tracking coyote movement in metropolitan areas shows the animals spend lots of time in natural settings, but a new study suggests the human element of city life has a bigger impact than the environment on urban coyote survival.
Researchers monitoring coyotes in Chicago found that habitat – areas with relatively high levels of vegetation cover and low levels of human infrastructure – did not influence coyote survival in positive or negative ways. Instead, areas densely populated with humans were ...
Science educator calls for climate change to be taught more in US schools
2025-01-09
Given that today’s children will inherit the consequences of climate change, schools are instrumental in mobilizing a global response to the climate crisis, a science educator argues.
Climate literacy advocate Kelley T. Lê argues that climate change is the defining issue of our time, and in her new book, Teaching Climate Change for Grades 6–12: Activating Science Teachers to Take on the Climate Crisis Through NGSS, Lê provides teachers, administrators, and global leaders with practical tools to empower ...
Realistic emission tests for motorbikes, mopeds and quads
2025-01-09
The emissions scandal in the automotive industry that came to light in 2015 has set many things in motion. Last but not least, the discussion about the need for realistic tests for vehicles in order to correctly determine their pollutant emissions instead of just testing on test rigs. Such tests and the applicable emission limits are now required by law for cars, but not for so-called category-L vehicles (mopeds, motorbikes, tricycles and quads). As part of the “LENS” project (L-vehicles Emissions and Noise mitigation Solutions) funded by the European ...
Race- and gender-based microaggressions linked to higher post-birth blood pressure
2025-01-09
Research Highlights:
More than one-third of Asian, Black and Hispanic women in the study group reported experiencing at least one microaggression related to race and gender during or after their pregnancy.
The link between racial microaggressions and postpartum blood pressure was strongest 10 or more days after delivery, when the blood pressure may be monitored less often, the researchers noted.
The researchers also noted that these types of gendered racial microaggressions can raise blood pressure postpartum and suggest blood pressure monitoring and/or treatment for high blood pressure may need to ...
Novel ‘quantum refrigerator’ is great at erasing quantum computer’s chalkboard
2025-01-09
If you’d like to solve a math problem on a good old-fashioned chalkboard, you want the board clean and free of any previous markings so that you have space to work. Quantum computers have a similar need for a clean workspace, and a team including scientists at the National Institute of Standards and Technology (NIST) has found an innovative and effective way to create and maintain it.
The research effort, a collaboration with physicists at Sweden’s Chalmers University of Technology, could address one of the main issues confronting quantum computer designers: ...
States struggle to curb food waste despite policies
2025-01-09
The United States generates more food waste than all but two countries. To address this, the federal government set a goal to cut food waste in half by 2030 compared to 2016 levels, to about 164 pounds per person annually. But a new study published in Nature Food and led by University of California, Davis, reveals that current state policies are falling short. Since 2016, per capita food waste has increased instead of decreasing.
“We’re just five years away from 2030 so it’s quite alarming how ...
