Neuropathic pain is a complex condition that can be difficult to treat, but research suggests that psychological factors play a crucial role. Dr. Bushnell's work highlights the importance of catching pain early and treating it aggressively, as well as exploring alternative approaches such as meditation and drawing
Dr. James Henry studies the electrical activity of nerve cells to understand how pain is transmitted to the brain. He hopes to establish collaborations among pain researchers and medical professionals to improve treatment options for patients suffering from chronic pain.
Dr. Robin Cohen developed the McGill Quality of Life (MQOL) Questionnaire to measure existential, physical, psychological, and social well-being in terminally ill patients. She emphasizes the importance of addressing cognition, emotion, and spiritual aspects of pain management.
Dr. Johnston's research focuses on reducing infant pain in preterm babies, finding skin-to-skin contact and sugar administration can be effective soothing methods. She also coaches pediatric nurses and promotes a pain awareness campaign to improve treatment options for infants and their families.
A landmark study published in Nature reveals that deaf and hearing adults who experienced language in early life perform similarly well in learning a new language later in life. Deaf adults with little language experience show low levels of performance, whereas those with early experience demonstrate high proficiency.
A longitudinal study of 1791 Brazilian women found that persistent HPV infections increased the risk of squamous intraepithelial lesions (SIL) by 10.2 times compared to those without infection. Women with persistent type 16 or 18 HPV infections had a strong correlation with SIL incidence.
New McGill researchers have been awarded $1.76 million in funding for new equipment and installations, with Quebec agreeing to match the amount. The funding will support various campus projects and research initiatives across multiple institutions affiliated with McGill.
Researchers at McGill University have isolated novel stem cells from the dermis of adult rodents that can differentiate into various cell types, including neurons and muscle cells. These multipotent stem cells, known as SKPs, hold promise for treating Parkinson's disease and other neural disorders.
A one-year pilot study will examine the effects of smoked cannabis on chronic neuropathic pain, with a focus on dosing and side effects. The trial will recruit 32 patients and use four strains of cannabis to assess pain intensity and quality of life.
Researchers using Chandra X-ray Observatory associate a pulsar with a historic supernova, dated back to 386 AD, providing strong evidence for the young age of the pulsar. The discovery challenges conventional wisdom on pulsars and their formation.
A team of scientists suggests that meteorites like ALH84001 could have transferred life between Mars and Earth. The analysis of the meteorite's magnetic field supports the hypothesis that meteorites can be an interplanetary delivery system capable of transferring life.
Dr. Sherwin's research suggests that estrogen replacement therapy prevents some of the decline in verbal memory and ability to learn new material in postmenopausal women. This effect has been observed even in women who underwent surgical removal of their ovaries, which led to a sudden drop in estrogen levels.
