How To Use Myofibril In A Sentence
-
Muscle catabolism is a hallmark of sepsis and results from accelerated breakdown of myofibrillar proteins, such as actin and myosin.
-
Fast-acting muscles have highly ordered structure due to the closely interrelated disposition of membranes and myofibrils.
-
Within the sarcolemma is the sarcoplasm, containing all the usual subcellular elements plus long prominent myofibrils.
-
In cross section, skeletal muscle fibers are seen to be composed of numerous small aggregates of contractile substance, the myofibrils.
-
For example, in relaxed myofibrils, it was unclear whether each Tmod striation could be unambiguously resolved into separate thin filament profiles.
-
Their idea was that the myofibril contains toothbrush-like structures facing one another and pushed together so that their bristles interpenetrate.
-
When the shape changes a calcium ion is let through the S.R. into the myofibril causing the filaments to get excited causing them to contract.
CreationWiki - Recent changes [en]
-
The changes consisted of disrupted myofibrils, increased numbers of lipid vacuoles in the sarcoplasm, and abnormally small mitochondria containing focal membrane disruptions.
-
Occasional myocytes in both ventricles showed hypereosinophilia and loss of myofibril structure without associated inflammation (changes regarded as agonal rather than representing intrinsic myocyte pathology).
PLoS ONE Alerts: New Articles
-
However, as the disease progresses, cardiomyocytes show deterioration in some mitochondrial as well as myofibril features, evidenced by swelling of mitochondria, misalignment of myofibril structure, and blurring as well as breakage of Z-lines.

-
Striated muscle tissue consists of bundles of fibers called fasiculi made up of long nucleated cells with myofibrils in alternating dark and light bands that give them a striped appearance.
Muscles Part 1
-
Inside the fibre are the myofibrils, which constitute the contractile apparatus, and a system for controlling the myofibrils through changes in calcium concentration.
-
The number of myofibrils within the enlarged muscle fiber can increase more than 10-fold.
-
Line scans were determined for portions of myofibrils that were straight, contained five or more sarcomeres, and had striations relatively perpendicular to the long axis of the myofibril.
-
Individual muscle cells are extremely elongated and enclose many-stranded cables woven from threads called myofibrils.
-
The appearance of Hand1 and Smyd1, transcription and chromatin remodeling factors; Acta1, Acta2, Myl3, and Myom1, myofibril proteins; and calcium-activated potassium-channel gene activity (KCNMB1), the channel protein, were powerfully attenuated in the
Proceedings of the National Academy of Sciences current issue
-
Structural abnormalities included loss of lateral alignment of myofibrils, perturbation of myofibril anchorage to the sarcolemma, abnormal mitochondrial number and organization, and loss of nuclear shape and positioning.
-
At 36 weeks of age, Tg mice (the group in transition from hypertrophy to HF) show significant degenerative changes in cardiomyocytes, including swelling of mitochondria, disruption of the nuclear membrane, and absence of myofibril structure.

Results: The content of protein, myofibril protein and myosinogen gradually descend, and nonprotein nitrogen(NPN) gradually increase along with the extend of fermented time.
-
B, Ge K, Farmer G, et al. (2003) Targeted disruption of the murine Bin1/Amphiphysin II gene does not disable endocytosis but results in embryonic cardiomyopathy with aberrant myofibril formation.
