Researchers have identified new roles for a protein long known to protect against severe flu infection – among them, raising the minimum number of viral particles needed to cause sickness.
روتشستر، ولاية مينيسوتا — أظهرت دراسة أجرتها مايو كلينك أن دعامة مصممة على شكل ساعة رملية قد تُحسن تدفق الدم وتخفف من آلام الصدر الشديدة والمتكررة لدى المصابين بمرض الأوعية الدقيقة. من بين 30 مشاركًا في تجربة سريرية من المرحلة الثانية، أفاد 76% بتحسن ملموس في حياتهم اليومية. على سبيل المثال، بعض المشاركين الذين كانوا غير قادرين على المشي حول الحي أو صعود الدَّرَج بسبب آلام الصدر تمكنوا من أداء هذه الأنشطة اليومية بنهاية التجربة السريرية التي بلغت مدتها 120 يومًا. كما أظهرت المقاييس السريرية لتدفق الدم المرتبطة بالأوعية الدقيقة في القلب تحسنًا كبيرًا أثناء المتابعة، وفقًا للنتائج المنشورة في مجلة الكلية الأمريكية لأمراض القلب: تدخلات أمراض القلب والأوعية الدموية (Journal of the American College of Cardiology: Cardiovascular Interventions).
Community partnerships led to a specialized clinic delivering COVID and flu shots to individuals with neurodevelopmental conditions like autism at the MIND Institute.
In a groundbreaking study, researchers at McMaster University have identified a potential treatment for Sandhoff and Tay-Sachs diseases—two rare, often fatal lysosomal storage disorders that cause progressive damage to nerve cells in the brain and spinal cord.
After years of investigating the diseases’ underlying mechanisms, the research team has identified an existing FDA-approved drug that could significantly improve quality of life for affected patients and their families.
A small clinical trial shows promising results for patients with triple-negative breast cancer who received an investigational vaccine designed to prevent recurrence of tumors. Conducted at Washington University School of Medicine in St. Louis with a therapy designed by WashU Medicine researchers, the trial is the first to report results for this type of vaccine — known as a neoantigen DNA vaccine — for breast cancer patients.
Results from a study in Malawi showed that chewing gum containing xylitol, a naturally occurring alcohol sugar, was associated with a 24% reduction in preterm birth. The findings were published today in Med (a Cell Press journal).
Researchers found that the group of pregnant individuals randomized to receive chewing gum also saw a 30% drop in low-birthweight babies, when compared with the control group which did not receive xylitol gum, noted lead author Dr. Greg Valentine, associate professor of pediatrics at the University of Washington School of Medicine.
The interplay between the genetic makeup of crops and the conditions in which they grow is difficult to untangle. A research team led by an Iowa State University professor aims to help breeders analyze the interactions to make crops more resilient and productive.
