The enzyme creatine kinase (CK) [EC 2.7.3.2] is a dimeric molecule consisting of two separate subunits Band M, giving rise to three isoenzymes CK-BB, CK-MB and CK-MM. Most of the CK found in the plasma of normal individuals is the MM isoenzyme derived from skeletal muscle, while the CK-MB fraction originates predominately from cardiac muscle. Normally there is little, if any, CK-BB isoenzyme pr...
One hundred patients with chest pain of cardiac origin were evaluated on the basis of clinical findings, electrocardiograph results, and total creatine kinase (CK) and creatine kinase B-subunit (CK-B) activity (as determined by immunoinhibition with the Boehringer CK-MB kit) in serum. All patients diagnosed as having had an acute myocardial infarction had increased values for both CK-B and tota...
BACKGROUND 20(S)-Protopanaxadiol 20-O-D-glucopyranoside, also called compound K (CK), exerts antidiabetic effects that are mediated by insulin secretion through adenosine triphosphate (ATP)-sensitive potassium (KATP) channels in pancreatic β-cells. However, the antidiabetic effects of CK may be limited because of its low bioavailability. METHODS In this study, we aimed to enhance the antidiab...
برای دستیابی به مزیت رقابتی در شرایط عدماطمینان که آن تغییر ضروری است، یکی از چالشهای بزرگ سازمانها کاهش ریسک طریق ایجاد زنجیرههای تأمین تابآور است. تابآوری زنجیره تأمین توانایی مقابله با اختلال اشاره دارد یک رویداد غیرقابلپیشبینی بوده و دارای منابع داخلی خارجی مختلفی ازجمله بلایای طبیعی ریسکهای عملیاتی پژوهش حاضر شبیهسازی توسط نرمافزار ارنا زنجیره سنگ ساختمانی «کارخانه سنگبری آسم...
OBJECTIVES We examined whether unloading of the left ventricle with a ventricular assist device (LVAD) can result in normalization of the creatine kinase (CK) abnormalities in the failing human heart. BACKGROUND Left ventricular failure is associated with a decrease of myocardial total CK activity and a fetal shift in CK isoform expression that results in an increase in the cytosolic brain ty...
The creatine kinase (CK) isoenzyme system is essential for motility in rooster and sea urchin sperm. In the present study, biochemical characterization as well as immunofluorescence and confocal laser microscopy with highly specific antibodies against various chicken CK isoenzymes revealed that cytosolic brain-type CK isoenzyme (B-CK) is the only CK isoenzyme in rooster seminal plasma, while th...
Let CK∗ denote the C ∗-algebra defined by the direct sum of all Cuntz-Krieger algebras. We introduce a comultiplication ∆φ and a counit ε on CK∗ such that ∆φ is a nondegenerate ∗-homomorphism from CK∗ to CK∗ ⊗ CK∗ and ε is a ∗-homomorphism from CK∗ to C. From this, CK∗ is a counital non-commutative non-cocommutative C ∗bialgebra. Furthermore, C∗-bialgebra automorphisms, a tensor product of repr...
Creatine kinase (CK) provides ATP buffering in skeletal muscle and is expressed as 1) cytosolic myofibrillar CK (M-CK) and 2) sarcomeric mitochondrial CK (ScCKmit) isoforms that differ in their subcellular localization. We compared the isometric contractile and fatigue properties of 1) control CK-sufficient (Ctl), 2) M-CK-deficient (M-CK[-/-]), and 3) combined M-CK/ScCKmit-deficient null mutant...
Aim: The aim of the study was to investigate the effects of in vitro hemolysis on serum creatine kinase and creatine kinase MB isoenzyme activities with creatine kinase MB mass, troponin I and myoglobin measurements. Materials and methods: We prepared serum pools having analyte concentrations at normal and pathological values. Hemolysate was added into serum pools to obtain aliquotes with final...
We evaluated the analytical performance of the immunoprecipitation technique for quantification of creatine kinase (CK; EC 2.7.3.2) isoenzyme MB, focusing on specimens with increased blank activities. The samples we studied had blank values that were equal to or greater than either 15 U/L or the uncorrected CK-MB value. Of 134 specimens selected, 16 and 21 contained macro CK type 1 and CK-BB, r...
