Changes In Brain Scans Seen After A Single Season Of Football For Young Players

MRI scans of the brains of young football players suggest that repeated blows to the head can change the shape of nerve fibers in the corpus callosum, which connects the two halves of the brain. (Image credit: groveb/Getty Images)

The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscope (HRTEM), X-ray photoelectron spectroscopy (XPS), Raman, electron spin-resonance (ESR) and surface photovoltage spectroscopy (SPS). The results reveal that SCFs c...

In this study, mechanical, histochemical and molecular assays were conducted to understand the mechanisms underlying the effects of Ca in fruit physical properties. In a two-year field trial, grapevines were sprayed with exogenous CaCl2 throughout the fruiting season. Results showed an increase in berry Ca concentration at harvest, associated to increased fruit consistency and skin resistance. Scanning electron microscopy showed that fruits from Ca-treated plants had smoother skin surfaces than control fruits, and that microcracks encircling the lenticels were less prominent. Histochemistry assays suggested higher depositi...

Powders of shells species (Dosinia exoleta and Ostrea edulis), with particle size fractions of 0.045 – 0.125 mm, 0.125 – 0.2 mm, and 0.2 – 1 mm, were subjected to degradation at the various heating rates (5, 10, 15 and 20&th...

ConclusionThis initial study found that DCE-MRI CoV was independently associated with malignancy in patients with suspected lung cancer. CoV has the potential to help diagnose indeterminate pulmonary lesions and may complement TIC-derived DCE-MRI metrics. Further studies are warranted to validate the diagnostic value of DCE-MRI intensity histogram analysis.

ConclusionOur study demonstrates that an AI solution can help radiologists to diagnose ICH and thus decrease the error rate. AI solution can serve as a prospective peer review tool for non-contrast head CT scans to identify ICH and thus minimize false negatives.

Despite the self-limiting nature of lateral epicondylitis (LE) the disease has a prolonged course in some patients. Currently there is no optimal treatment of choice for these patients. We treated 6 elbows in 5 patients with LE with free fat grafting. All patients had symptomatic LE (symptom duration>2 y) and magnetic resonance imaging scan consistent with LE, and no finding of osteoarthrosis of the elbow joint, ligament injury, or other condition causing palpable lateral elbow pain. The fat graft was harvested from the abdomen, centrifuged or decanted and 10 mL was injected in and around the lateral epico...

(CAPE CANAVERAL, Fla.) — NASA’s newest Mars lander has confirmed that quakes and even aftershocks are regularly jolting the red planet. Scientists reported Monday that the seismometer from the InSight spacecraft has detected scores of marsquakes. A series of research papers focus on the 174 marsquakes noted through last September. Twenty-four were relatively strong — magnitude 3 to 4 — and apparently stemmed from distant underground triggers. The rest were smaller, with uncertain magnitude and origin. Even the stronger quakes would not have posed a hazard to anybody on the planet’s surface, re...

Some victims ’ diagnosis of HIV and hepatitis C was withheld for years, hearing toldThe guilt of infected blood donors and the anger of victims whose diagnosis of HIV and hepatitis C was withheld from them for years has emerged as evidence given in secret was read out to a public hearing in London.On Monday, witnesses who did not want to appear in person had their testimony delivered by intermediaries who interviewed them for the infected blood inquiry. It is examining how as many as 30,000 people became severely ill after being givencontaminated blood products by the NHS in the 1970s and 80s; many have since died.Continue reading...
