Different impact of ALS on laminin isoforms in human extraocular muscles versus limb muscles.
PURPOSE To determine the impact of amyotrophic lateral sclerosis (ALS) on the extraocular muscles (EOMs) by examining the laminin isoform composition of the basement membranes (BMs) in EOMs and limb muscles from donors with ALS. METHODS Muscle samples collected at autopsy from ALS donors and from transgenic mice overexpressing human superoxide dismutase type I mutations (D90A or G93A), and ag...
متن کاملMyosin heavy chain 2B isoform is expressed in specialized eye muscles but not in trunk and limb muscles of cattle.
Myosin heavy chain isoforms (MHC) of adult skeletal muscles are codified by four genes named: slow, or type 1, and fast types 2A, 2X and 2B. The slow, 2A and 2X isoforms have been found expressed in all mammalian species studied so far whereas there is a large inter-species variability in the expression of MHC-2B. In this study histochemistry (m-ATPase), immunohistochemistry with the use of spe...
متن کاملLimb muscles are androgen targets in an acrobatic tropical bird.
Spectacular athleticism is a conspicuous feature of many animal courtship displays yet surprisingly little is known about androgen dependence of skeletal muscles underlying these displays. Testosterone (T) acts through androgen receptors (ARs) to stimulate muscular male Golden-collared manakins of Panama to perform a remarkably athletic courtship display that includes loud wingsnaps generated b...
متن کاملReliability of Eelectromyography of Abdominal Muscles During Abdominal Manoeuvre with and without Pelvic Floor Muscle Contraction
Objective: The purpose of this study was to determine the reliability of electromyography measurements of abdominal muscles activity during different manoeuvres (pelvic floor muscle (PFM) contraction, abdominal hollowing and abdominal bracing with and without PFM contraction) in subjects with and without chronic low back pain (LBP). Materials & Methods: In this methodology research 21 subjec...
متن کاملAre muscles mechanically independent?
MOST PHYSIOLOGY TEXTS imply that the mechanism by which force is transmitted from sarcomeres to muscle insertions is simple: when skeletal muscles contract, cross-bridge forces are transmitted along myofibrils, through the sarcolemma and extracellular matrix to tendons and, ultimately, bones. At each level of organization, myofibrils, muscle fibers, and muscles behave as mechanically independen...
