OBJECTIVE To determine whether cardiac troponin T increases after electrical cardioversion in patients with atrial fibrillation or atrial flutter. DESIGN Serum creatine kinase (CK), creatine kinase-MB (CKMB), and cardiac troponin T were measured before, 24 hours, and 48 hours after cardioversion in 15 patients with atrial fibrillation or atrial flutter. RESULTS 12 of the 15 patients (80%) w...

BACKGROUND: Cardiac Troponin I (cTnI) is known as a cardiac biomarker in determining the myocardial damage of diseases which affect the heart muscle. OBJECTIVES: This study aims to evaluate the serum cTnI concentration in Markhoz Breed goats suffering selenium (Se) deficiency and its correlation with electrocardiographic parameters, and activity of creatine kinase (CK) and aspartate aminotransf...

Creatine kinase (CK) forms a small family of isoenzymes playing an important role in maintaining the concentration of ATP and ADP in muscle cells. To delineate the impact of a lack of CK activity, we studied contractile performance during a single maximal tetanic contraction and during 12 repeated tetanic contractions of intact dorsal flexors of CK knockout (CK(-/-)) mice. To investigate the ef...

Two isoforms of creatine kinase (CK; ATP:creatine N-phosphotransferase, E.C. 2.7.3.2), brain type (BB-CK) and mitochondrial type (MiMi-CK), but not the muscle types (MM- or hybrid MB-CK), were identified by cellulose polyacetate electrophoresis and immunoblots in retina from adult chickens. Indirect immunofluorescence labeling of cryosections of retinas revealed high concentrations of BB-CK in ...

background: cardiovascular system is a very importantorgan that plays a vital role in tissue function. in farm animals,the growth and high milk production depends on function ofcardiovascular system. objectives: cardiovascular health inhigh and low-yielding dairy cows was investigated. methods:fifty 4-year-old high- yielding holstein dairy cows and fifty 4-year-old low- yielding holstein dairy ...

Objective. Creatine kinase (CK), cathepsin D (CTSD), Ki67, and tumour protein 63 (p63) have been proven to participate in the growth of some cancers. However, available literature suggested paucity data on their involvement oesophageal squamous-cell carcinoma (ESCC) development. Methods. We ascertained presence CK, CTSD, p63 expressions ESCC demonstrate association between differentiation above...

Electrophoretic separation of creatine kinase (ATP: creatine phosphotransferase, E.C. 2.7.3.2) isoenzymes in agarose gel was made in the serum of 93 sheep of three Slovenian domestic breeds (Solcavska, Pramenka and Bovska breeds). 44 sheep were pregnant between 112 and 135 days at the time of the blood collection. The median value of serum total CK activity for all animals investigated was 82 U...

From an extensive model developed to interpret physiological processes we are able to show that the observed elevated creatine kinase-myoglobin (CK-MB) and serum concentration of cardiac troponin T (cTnT) values for a particular patient are associated with the inflammatory disease, polymyositis, and not myocardial injury. This highlights that caution must be exercised in using elevated CK-MB an...

Creatine kinase-MB isoenzyme release (CK-MB-g-Eq) was correlated with left ventricular (LV) radionuclide gated blood pool wall motion estimates of percent abnormally contracting regions (%ACR), ejection fraction (EF) and quantitative thallium-201 (Tl-201) LV perfusion scintigraphy (Tl-201 perfusion index) during evolving myocardial infarction (MI). Of the 35 patients, 14 had no evidence of eith...

A single-blind study of dystrophin staining in skeletal muscle was performed in 13 biopsies from carriers of Duchenne Muscular Dystrophy (DMD) and controls. The results indicate that immunohistochemical analysis of dystrophin staining is a valuable diagnostic test for DMD carriers when DNA for testing is unavailable from critical family members or is uninformative, when creatine kinase (CK) val...
