Abraham.Summary: "Strain imaging (also known as speckle-tracking echocardiography or STE) is a rapidly growing, affordable, and versatile cardiac imaging technology of great interest to clinicians in both inpatient and outpatient settings. ASE's Comprehensive Strain Imaging is the first reference designed to help you master a wide range of strain imaging/STE applications, including screening, diagnosis, treatment, and follow up"--Publisher's description.

Future applications of strain imaging. - ArticlePhosphorylation of adenosine 5'-monophosphate by a dialyzed cell-free extract from Escherichia coli.Chalykoff P, Yamazaki H.Can J Biochem. 1978 Aug;56(8):838-41.A cell-free extract of Escherichia coli, even after exhaustive dialysis, was found capable of phosphorylating adenosine 5'-monophosphate (AMP) to adenosine 5'-diphosphate (ADP) and adenosine 5'-triphosphate (ATP). Centrifugation at 100 000 g for 3h sedimented most of the capacity to phosphorylate AMP to ATP, while the supernatant retained a significant capacity to phosphorylate AMP to ADP. The pellet contained a greater amount of phosphate polymers (which were neither DNA, RNA, nor proteins) than did the supernatant. The addition of authentic inorganic polyphosphates to the supernatant restored the phosphorylating capacity of the original extracts. It is concluded that the observed phosphorylation is partly due to inorganic polyphosphate.
