Heart disease patients who sit a lot have worse health even if they exercise

Patients with coronary artery disease spend an average of eight hours each day sitting despite exercising, according to research published in the European Journal of Cardiovascular Prevention. Women tend to be less sedentary than men, but both have poorer health outcomes when sitting for long periods.

Optimal care for older cancer patients should target relevant HRQOL domains according to EORTC study

A recent EORTC study identified key health-related quality of life (HRQOL) components to prioritize in caring for older cancer patients. The study found that HRQOL improves with age for social functioning and financial problems, while physical functioning and constipation worsen.

Better blood pressure control -- by mobile phone

Researchers developed an interactive mobile phone system to help patients with high blood pressure self-manage their condition, leading to significant reductions in systolic and diastolic blood pressure. The system, which includes patient reports, lifestyle feedback, and reminders, also improved patients' understanding of the connectio...

Can physical exercise enhance long-term memory?

A new study published in Brain Plasticity reports that running mice developed twice the normal number of new neurons and showed improved ability to distinguish between similar objects. This improvement in pattern separation is crucial for everyday memory tasks like remembering chess piece shapes or patterns on a board.

New strategy discovered for treating arthritis

Researchers at Queen Mary University of London have found that arthritic cartilage can be treated by a patient's own microvesicles, which can travel into cartilage cells and deliver therapeutic agents. The study suggests that these microvesicles could be a novel form of therapy for patients with cartilage damage due to various diseases.

Lactate for brain energy

Researchers from the University of Zurich have confirmed the existence of a concentration gradient of lactate between astrocytes and neurons in the intact mouse brain. The study provides new evidence for an exchange of lactate between different brain cells, supporting a 20-year-old hypothesis on brain energy metabolism.

People who rely on their intuition are, at times, less likely to cheat

A study by University of Missouri graduate student Sarah Ward found that people who trust their gut feelings are less likely to cheat after considering past immoral behavior. Participants in the experiment were asked to imagine acting immorally and then complete an unsolvable IQ test, with results showing that up to 23% cheated. The re...

Cataract surgery lessens patients' dizziness

After routine cataract surgery, older people experience significantly less dizziness due to improved vision. However, wearing multifocal glasses after surgery may negate this benefit, particularly for those with frailty or frequent spectacle changes.

Coming out of their evolutionary shells

A comprehensive genomic study of turtle shells has identified unique adaptations in genes that control hard cutaneous layers, dating back to the evolution of claws and feathers. The study also reveals a shared genetic organization between turtles and humans, highlighting the common ancestry of these defense mechanisms.

Cheesy products

Researchers from the University of Veterinary Medicine, Vienna tested over 100 raw milk cheeses purchased online and found that pathogenic bacteria like Listeria monocytogenes were present in two samples. Furthermore, more than half of the products lacked proper cooling, leading to increased bacterial growth during transport.

A sticky breakthrough

Researchers at UC Santa Barbara have designed a synthetic material that combines the key functionalities of interfacial mussel foot proteins, creating a single, low-molecular-weight, one-component adhesive. This breakthrough technology demonstrates record-high wet adhesion up to 10 times more effective than previous materials, with app...
