Sentence examples for muscle fiber subtypes from inspiring English sources

These splicing changes are accompanied by changes in endomysial and perimysial spacing, increased variation in muscle fiber size, and switching of muscle fiber subtypes.

Myosin heavy chains (MYHs) form a large gene family that includes sarcomeric MYHs, major contractile proteins of striated muscles that are expressed in a spatio-temporal manner defining the functional properties of different muscle fiber subtypes [ 1].

Other studies demonstrated an abnormal proportions of type 2 muscle fiber subtypes[ 10- 12] In addition to such relative sarcopenia and abnormal muscle fibres composition, PWS patients show a reduced pattern of spontaneous physical activity [ 13].

Typically, increased oxidative capacity and lipid use in muscle is accompanied by a switch in muscle fiber subtype, a phenomenon that is facilitated by peroxisome proliferator-activated receptor gamma co-activator 1-alpha (PGC-1α), the master regulator of mitochondrial biogenesis and function (Wu et al, 1999; Lin et al, 2002).

During ALS disease progression, a progressive shift in skeletal muscle fiber subtype from fast twitch to slow twitch would presumably result in a concomitant shift toward more oxidative metabolism (Dengler et al, 1990; Frey et al, 2000; Pun et al, 2006; Deforges et al, 2009).

We combined three different methods in the same muscle preparation: (1) the uptake of activity-dependent dyes into selected axon terminals to define the spinal segmental origin of a peripheral nerve terminal; (2) the fluorescent labeling of nicotinic acetylcholine receptors to determine motor endplate size; (3) the immunocytochemical staining of skeletal muscle to determine fiber subtype.

However, in ocular MR muscles the mATPase histochemistry alone was insufficient to completely distinguish fiber subtypes although a variable incubation time in alkaline and acid media had been used within a wide span of pH values [ 39, 50, 51].

c Role of muscle fiber cellularization in limb regeneration.

The muscle fiber (axon) is very long, it travels a long distance towards its target (muscle).
