Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

A team of researchers has identified an intermediate stage in virus-cell fusion that lasts several minutes, providing a potential window of opportunity for drug development. This discovery may allow existing drugs to be re-evaluated and fine-tuned to target this critical point in the viral entry process.

Consumers suspicious of sponsored links

A study by Penn State researchers found that 80% of participants preferred organic search results over sponsored links. Despite identical content, participants rated sponsored links as less relevant due to biased perception. To address this, businesses should prioritize organic visibility alongside paid advertising.

US specialists call for heart patients to be screened for psychological distress

Research by Dr Amy Ferketich and Dr Philip Binkley found that men and women with heart disease in the US experience high levels of psychological distress, with only a third seeking mental health support. The study analyzed data from over 17,000 individuals with different forms of heart disease, highlighting the need for clinicians to c...

Are microRNAs oncogenes?

Researchers discovered distinctive patterns of microRNA activity in cancer cells that can be used to diagnose cancers and distinguish normal cells from those that are cancerous. The study also found that specific microRNAs can cause lymphomas in mice and cooperate with genes already known to cause human cancers.

Women overestimate breast cancer risk, U-M study finds

A recent study published in Patient Education and Counseling found that 89% of women overestimated their lifetime risk of breast cancer, with an average estimate of 46%. Women who did not provide an estimate beforehand were more likely to feel anxious, while those who provided an estimate reported relief after learning the actual risk ...

Raisins fight oral bacteria

The study found that oleanolic acid and other compounds in raisins inhibited the growth of oral bacteria associated with caries and gum disease. Raisin phytochemicals were effective against Streptococcus mutans and Porphyromonas gingivalis at concentrations ranging from 200 to 1,000 micrograms per milliliter.

Studies reveal how cells sense oxygen

Research reveals that mitochondrial activity produces reactive oxygen species that signal low oxygen levels, allowing cells to adapt and respond. Cells with disabled mitochondria fail to detect changes in oxygen availability, highlighting the critical role of mitochondria in oxygen sensing.

Link between mothers' poor diets, kids' obesity

A study published in Cell Metabolism suggests that premature leptin surge in newborn mice of underfed mothers leads to remodeling of key brain circuits contributing to obesity later in life. The researchers found that the early leptin surge alone causes accelerated weight gain.
