Scientists find strong evidence that wasting syndrome is the same for all organisms

An interdisciplinary team of Dutch researchers has discovered that wasting syndrome, a severe byproduct of tuberculosis, is the same for all humans and animals studied. The discovery offers new opportunities to investigate the still insufficiently understood condition. The scientists also developed a promising method for diagnosing and possibly even predicting tuberculosis. Professor of Molecular cell biology Herman Spaink (Institute of […]

It’s inappropriate to consider blanket do-not-resuscitate orders for COVID-19 patients because adequate data is not yet available on U.S. survival rates for in-hospital resuscitation of COVID-19 patients and data from China may not relate to U.S. patients, according to a new article published today in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal. There is a presumption that COVID-19 […]

New evidence shows cytotoxic T cells can identify, invade, and destroy targets of large mass like T. gondii tissue cysts

CD8+ cytotoxic T lymphocytes can kill host cells infected with various microorganisms as well as single individual cancer cells through direct cell-to-cell contact, but their ability to destroy a target of large mass remains unexplored. A study in The American Journal of Pathology provided novel evidence on the capability of the immune system to eliminate large parasite-filled cysts associated with […]

New evidence: It’s not necessary to fast before complete cholesterol test

A new study adds to the growing body of evidence that it is unnecessary for most patients to fast before having bloodwork done to measure lipid levels to determine risk of future cardiovascular events. Since the 1970s, studies have suggested that fasting and nonfasting before a complete cholesterol test, otherwise known as lipid level testing, may make little difference in […]

Scientists find first evidence for necessary role of the human hippocampus in planning

A team of scientists reports finding the first evidence that the human hippocampus is necessary for future planning. Its findings, published in the journal Neuron, link its long-established role in memory with our ability to use our knowledge to map out the future effects of our actions. The results have implications for the way we think about afflictions that affect […]

Data show no evidence that teens’ social media use predicts depression over time

Longitudinal data from adolescents and young adults show no evidence that social media use predicts later depressive symptoms, according to research published in Clinical Psychological Science, a journal of the Association for Psychological Science. However, the findings do show that relatively higher depressive symptoms predicted later social media use among adolescent girls. This research stands in contrast with recent claims […]
