1. We examined the effects of the novel thiadiazinone derivative EMD 57033 on developed force and intracellular [Ca 2+ ] in cardiac muscle during control conditions (pH 7.35) and in acidosis (pH 6.8). (portlandpress.com)

Additional features include acidosis, hypertension, convulsions and respiratory failure. (brainkart.com)

While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles known as intercalated discs. (wikipedia.org)

Skeletal muscles attach to the skeleton and come in pairs -- one muscle to move the bone in one direction and another to move it back the other way. (howstuffworks.com)
He explained, "Traditionally, cardiac surgery required opening the chest in the front and sternum, a bone in the chest. (newsx.com)
However, "MICS allows selected patients to undergo cardiac surgery through smaller incisions made from the side, avoiding the need to open the chest bone. (newsx.com)

Power was reduced in the upper and lower limb muscles (Medical Research Council grade 3-4 out of 5). (cdc.gov)

Initial, CAPN3 is AZ-33 normally mostly muscle-specific (9), but is normally detectable in zoom lens, liver, human brain and cardiac muscles during advancement (10C13). (exposed-skin-care.net)
In contrast to GSD type I, liver and skeletal muscles are involved in GSD type III. (medscape.com)

We employ an array of imaging techniques to study "structural physiology" of cardiac and skeletal muscle. (hopkinsmedicine.org)

Skeletal muscle, is voluntary muscle anchored by tendons or sometimes by aponeuroses to bones, and is used to effect skeletal movement such as locomotion and to maintain posture. (wikipedia.org)
Which of the following is a voluntary muscle? (topperlearning.com)
