Q: The Eagles looked to win their 6th game in a row against the winless 49ers. The Eagles got off to a slow start, only leading 3-0 after the first quarter. Late in the second quarter, the Eagles blew the game open. Carson Wentz found tight end Zach Ertz for a 1-yard touchdown in the back of the end zone off of a bootleg pass, and Jalen Mills intercepted rookie QB C.J. Beathard and returned it 37 yards for a touchdown. The 49ers appeared to have some life in the third quarter, following a Carson Wentz interception, leading to a Matt Breida 22 yard touchdown reception. However, the Eagles responded, with Wentz connecting with Alshon Jeffery for a 53-yard touchdown, putting the game out of reach. The Eagles went on to win 33-10 and advanced to 7-1 on the season. Despite the win, the Eagles played a sloppy game in a rainy afternoon at the Linc.

A: Which player had the longest touchdown catch?

Q: Machado-Joseph disease (MJD), also known as spinocerebellar ataxia type 3 (SCA3), may be the most common dominantly inherited ataxia in the world. Here I will review historical, clinical, neuropathological, genetic, and pathogenic features of MJD, and finish with a brief discussion of present, and possible future, treatment for this currently incurable disorder. Like many other dominantly inherited ataxias, MJD/SCA3 shows remarkable clinical heterogeneity, reflecting the underlying genetic defect: an unstable CAG trinucleotide repeat that varies in size among affected persons. This pathogenic repeat in MJD/SCA3 encodes an expanded tract of the amino acid glutamine in the disease protein, which is known as ataxin-3. MJD/SCA3 is one of nine identified polyglutamine neurodegenerative diseases which share features of pathogenesis centered on protein misfolding and accumulation. The specific properties of MJD/SCA3 and its disease protein are discussed in light of what is known about the entire class of polyglutamine diseases.
