Donnan Potential of Rabbit Skeletal Muscle Myofibrils I: Electrofluorochromometric Detection of Potential [PDF]
, 1975 The fluorescence of the dye CC 6 [(3 hexyl 2 (3 hexyl 2 benzoxazolinylidene) 1 propenyl) benzoxazolium iodide] was shown to indicate Donnan potentials in rabbits skeletal muscle myofibrils.

ATPase Activity and Calcium Sensitivity of Myofibrils in Rabbit Red Muscle. [PDF]
家兎赤筋myofibrilsのATPase活性に対するCaおよびEGTAの作用を検討し次の結果を得た.1)赤筋myofibrilsのATPase活性は0.04μmoles Pi/mg protein/minであり,白筋のそれ(0.6μmoles Pi/mg protein/min)の1/4であった.2)赤筋および白筋myofibrilのATPase活性は,反応混液中のCaイオン濃度の増加(pCaの減少)にともなって増加した.pCa7.9-5,2の範囲で,両者のmyofibrilsのATPase活性は ...

Effect of Thymol on the“ Intrinsic Granules” in Rabbit Skeletal Myofibrils. [PDF]
myofibrilsの“intrinsic granules”に対するthymolおよびagingの効果をmyofibrillar ATPase活性の面から検討し,次の成績を得た。1.Thymol飽和溶液により0。C時間処理されたmyofibrilsのATPase活性は,きわめて低かった。2.Thymol飽和溶液による処理時間の増力に伴い,myofibrilsのATPase活性は増強した。3.Thymol飽和溶液で室温,1間処理すると,myofibrilsATPase活性は著明に増強した。4 ...

Tension-driven multi-scale self-organisation in human iPSC-derived muscle fibers
eLife, 2022 Human muscle is a hierarchically organised tissue with its contractile cells called myofibers packed into large myofiber bundles. Each myofiber contains periodic myofibrils built by hundreds of contractile sarcomeres that generate large mechanical forces.

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

Myofibril diameter is set by a finely tuned mechanism of protein oligomerization in Drosophila
eLife, 2019 Myofibrils are huge cytoskeletal assemblies embedded in the cytosol of muscle cells. They consist of arrays of sarcomeres, the smallest contractile unit of muscles.

EFFECT OF PROTEIN OXIDATION ON PARTICLE SIZE OF MYOFIBRILS [PDF]
, 2016 In order to study the effect of protein oxidation on the structure of myofibrils, extracted myofibrils from porcine longissimus dorsi muscle were incubated with different concentrations of the oxidant NaClO (0, 5, 10, 20 and 40 mM) at 5 ºC for 16 h ...
