i,j cijxjdxi, cij ∈ C. The integrability condition ω ∧ dω = 0 implies that ω1 ∧ dω1 = 0. Let C be the matrix (cij)i,j ∈ Mn×n(C). Writing down explicitly the integrability condition, the coefficient of dxi ∧ dxj ∧ dxk (i < j < k) in ω1 ∧ dω1 is ci(ckj − cjk)− cj(cki − cik) + ck(cji − cij), where ci = ∑n j=1 cijxj . Two cases appear: (1) C is a symmetric matrix. (2) C is not symmetric. So, it exi...

an experiment was conducted to evaluate the effects of dietary crude protein (cp) and lysine levels on performance and nitrogen excretion in broiler chickens. four hundred twenty 7-day old chickens from ross 308 strain were randomly allotted to 6 dietary treatments with 5 replicates of 14 chicks each (7 male and 7 female chicks). the cp levels were 17, 18, and 20 percent and lysine levels were ...

The function of creatine kinase (CK) and its effect on phosphorus metabolites was studied in livers of transgenic mice expressing human ubiquitous mitochondrial CK (CK-Mit) and rat brain CK (CK-B) isoenzymes and their combination. (31)P NMR spectroscopy and saturation transfer were recorded in livers of anesthetized mice to measure high-energy phosphates and hepatic CK activity. CK reaction vel...

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...

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...

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...

This study investigated the protective effect of fish oil (FO) on cisplatin (CP) toxicity in the rat liver. Twenty-eight rats were divided equally into four groups, with the first being a control group. The second group (CP group) was given 7 mg/kg of CP and the third group (FO group) was given 1 FO softgel/rat/day for 14 days. The rats in the fourth group (CP + FO group) were treated with both...

conclusions oral mg supplementation did not protect the cp induced nephrotoxicity in diabetic rats. results cp administration in normoglycemic rats significantly elevated the serum levels of blood urea nitrogen (bun) and creatinine (cr) (p < 0.05). however, coadministration of cp and mg statistically increased the serum levels of bun and cr in both normoglycemic and diabetic animals when compar...

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...
