Left-Handed People Are Being Unnecessarily Excluded From Neuroimaging Research, Study Finds

By Matthew Warren In a world made for right-handed people, life can sometimes be frustrating if you are among the 10% or so who are “adextral” — that is, left-handed or ambidextrous. Now a new grievance can be added to the list. Brain imaging researchers are systematically excluding adextrals from participating in their studies, according to an analysis of recent research papers published in top neuroimaging journals. Yet there’s no good reason to exclude this population, say the authors — and in fact, the practice could be detrimental to research. The tendency to include only right-handed people in neuroimaging research stems from the finding that certain processes are represented differently in the brains of adextrals. In particular, while the left hemisphere of the brain dominates language processing in almost all right-handed people, in about 30% of adextrals this processing occurs predominantly in the right hemisphere (or both hemispheres). Handedness also influences how the brain represents sensation and movement of the hands. Many neuropsychologists have therefore avoided recruiting adextrals for fear of affecting their data. But Lyam Bailey and colleagues at Dalhousie University noticed that researchers were excluding adextrals from a range of studies unrelated to language or movement, even though there is little evidence that handedness influences other processes. So in their new paper, published in the European of Journal of Neuroscien...

This study aims to examine the effectiveness of the postural treatment of the Mézières method on elite rhythmic gymnastics athletes with low back pain. DESIGN: Double-blind, randomized, controlled trial. SETTING: The sports hall of "Puente Tocinos," Murcia, Spain. PARTICIPANTS: Ninety gymnastics athletes were randomized into 2 parallel groups (intervention: n = 39; control: n = 51), of whom 98.9% were women (women = 89; man = 1). INTERVENTION: The Mézières method postural therapy was implemented. It lasted about 60 minutes in repeated sessions of 2 to 3 meetings per wee...

CONCLUSIONS: Delayed activation of the VM registered in females determines an increase in anterior shear force, which is an important risk factor for incurring an ACL injury. This testing protocol becomes adequate for the screening of high-risk athletes and for targeting interventions to specific imbalances that may increase injury risk.

Authors: Fyock M, Cortes N, Hulse A, Martin J Abstract Clinical Scenario: Patellofemoral pain (PFP) is a common knee injury in recreational adult runners, possibly caused by faulty mechanics. One possible approach to reduce this pain is to retrain the runner's gait. Current research suggests that no definitive gold standard treatment for PFP exists. Gait retraining utilizing visual feedback may reduce PFP in both the short and long term. Clinical Question: In adult runners diagnosed with PFP, does gait retraining with real-time visual feedback lead to a decrease in pain? Summary of Key Findings: A literature search...

We carry out eight configurations, mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, and octavacancies by using the density-functional-theory calculations (DFT). We calculate formation and dissociation energies to analyze the stability by finding the magic numbers. Magic numbers are the number of vacancy belonging to stable configurations. We find that di-, tetra-,...

Authors: Gabella G Abstract All the cells of rat detrusor muscle fall into one of five ultrastructural types: muscle cells, fibroblasts, axons and glia, and vascular cells (endothelial cells and pericytes). The tissue is ~79% cellular and 21% non-cellular. Muscle cells occupy 72%, nerves ~4% (1/3 axons, 2/3 glia), and fibroblast>3% of space. Muscle cells (up to 6 µm across and ~600 µm long, packed to almost 100,000 per mm2) have surface-to-volume ratio of 2.4 µm2/µm3 ~93% of cell volume is contractile apparatus, 3.1% mitochondria and 2.5% nucleus. Cell profiles are irregular but section...
