We have approached the study of this disorder by growing normal and diseased human muscle in a primary tissue culture system and investigating some of the electrical properties of the resulting myotubes. The most distinctive abnormality noted in MyD myotubes was an increased tendency to fire repetitive action potentials. A decreased action potential afterhyperpolarization amplitude and the presence of depolarizing afterpotentials were also noted, as were a decreased resting membrane potential, decreased action potential amplitude and overshoot, and decreased outward-going rectification. Although the ionic basis of these abnormal properties in vitro is not clearly defined, changes in the slow outward-going potassium current offer the best explanation. Furthermore, MyD cell culture offers a valuable model for critical analysis of the molecular mechanisms underlying MyD deficits.","address":"","school":"","issn":"0027-8424","doi":"","isi":"","pubmed":"6941262","key":"Merickel1981","howpublished":"","urllink":"","refid":73,"weight":73} , {userid:"mmckeown", "refid":"235","repocollections":"","attachment":"","_thumb":"","articletype":"article","sectionheading":"","title":"Altered EEG alpha and theta oscillations characterize apathy in Parkinson's disease during incentivized movement \r\n","year":"2019","author":"M Zhu, A HajiHosseini, TR Baumeister, S Garg, S Appel-Cresswell, MJ McKeown\r\n","journal":"NeuroImage: Clinical","volume":"23","number":"101922","pages":"","month":"Jul","doi":"10.1016\/j.nicl.2019.101922","pubmed":"31284232","pdflink":"","urllink":"","abstract":"","note":"","tags":"","weight":235} , {userid:"mmckeown", "refid":"298","repocollections":"","attachment":"","_thumb":"","articletype":"article","sectionheading":"","title":"Apathy scores in Parkinson\u2019s disease relate to EEG components in an incentivized motor task","year":"2024","author":"S.

Whether neutralizing dietary acid with alkaline potassium salts results in sustained improvements in calcium balance remains controversial. In this randomized, double-blind, placebo-controlled study, 52 men and women (mean age 65.2\u2009\u00b1\u20096.2 years) were randomly assigned to potassium citrate 60\u2009mmol\/d, 90\u2009mmol\/d, or placebo daily with measurements of bone turnover markers, net acid excretion, and calcium metabolism, including intestinal fractional calcium absorption and calcium balance, obtained at baseline and at 6 months. At 6 months, net acid excretion was significantly lower in both treatment groups compared to placebo and it was negative, meaning subjects' dietary acid was completely neutralized (-11.3\u2009mmol\/d on 60\u2009mmol\/d; -29.5\u2009mmol\/d on 90\u2009mmol\/d, p\u2009<\u20090.001 compared to placebo). At 6 months, 24-hour urine calcium was significantly reduced in persons taking potassium citrate 60\u2009mmol\/d (-46\u2009\u00b1\u200915.9\u2009mg\/d) and 90\u2009mmol\/d (-59\u2009\u00b1\u200931.6\u2009mg\/d) compared with placebo (p\u2009<\u20090.01). Fractional calcium absorption was not changed by potassium citrate supplementation. Net calcium balance was significantly improved in participants taking potassium citrate 90\u2009mmol\/d compared to placebo (142\u2009\u00b1\u200980\u2009mg\/d on 90\u2009mmol\/d versus -80\u2009\u00b1\u200954\u2009mg\/d on placebo; p\u2009=\u20090.02). Calcium balance was also improved on potassium citrate 60\u2009mmol\/d, but this did not reach statistical significance (p\u2009=\u20090.18). Serum C-telopeptide decreased significantly in both potassium citrate groups compared to placebo (-34.6\u2009\u00b1\u200939.1\u2009ng\/L on 90\u2009mmol\/d, p\u2009=\u20090.05; -71.6\u2009\u00b1\u200940.7\u2009ng\/L on 60\u2009mmol\/d, p\u2009=\u20090.02) whereas bone-specific alkaline phosphatase did not change. Intact parathyroid hormone was significantly decreased in the 90\u2009mmol\/d group (p\u2009=\u20090.01). Readily available, safe, and easily administered in an oral form, potassium citrate has the potential to improve skeletal health. Longer-term trials with definitive outcomes such as bone density and fracture are needed.","address":"","school":"","issn":"1523-4681","doi":"10.1002\/jbmr.1764","isi":"","pubmed":"22991267","key":"Moseley2013","howpublished":"","urllink":"","refid":12,"weight":12} , {userid:"mmckeown", "refid":"222","repocollections":"","attachment":"","_thumb":"","articletype":"article","sectionheading":"","title":"Habitual exercisers versus sedentary subjects with Parkinson's Disease: Multimodal PET and fMRI study","year":"2018","author":"MA.

The device, a crystalline solid-state realization of a dielectric antenna, is engineered for individual nitrogen-vacancy electronic spins in diamond. We demonstrate a directionality close to 10. The photonic structure preserves the high spin coherence of single-crystal diamond (T2\u2273100\u2009\u2009\u03bcs). The single-photon count rate approaches a megahertz facilitating efficient spin readout.
