Aging often leads to general cognitive decline in domains such as memory and attention.The effect of aging on numerical cognition, particularly on foundational numerical skills known as the Number Sense, is not well known.Early research focused on the effect of aging on arithmetic.Recent studies have begun to investigate the impact of healthy aging
Abstract The current opioid crisis urgently calls for developing non-addictive pain medications.Progress has been slow, highlighting the need to uncover targets with unique mechanisms of action.Extracellular adenosine alleviates pain by activating the adenosine A1 receptor (A1R).However, efforts to develop A1R agonists have faced obstacles.The equi
ObjectiveTo evaluate the change of the risk of bias (RoB) of acupuncture randomized controlled trials (RCTs) in the past five decades.MethodsMultiple databases were searched.We included RCTs identified from systematic reviews (SRs) on acupuncture.General characteristics and RoB judgment for each domain were extracted.The proportions of RCTs at high
