Microfluidic Study of Enhanced Oil Recovery during Flooding with Polyacrylamide Polymer Solutions.

A series of experiments have been carried out on the flooding of microfluidic chips simulating a homogeneous porous structure with various displacement fluids. Water and polyacrylamide polymer solutions were used as displacement fluids. Three different polyacrylamides with different properties are considered.

[Clinical and cost effectiveness of percutaneous coronary intervention for patients with chronic coronary artery disease during overnight hospitalization].

Aim: To evaluate cost effectiveness of coronary endovascular treatment in patients with stable IHD during "one-night" hospitalization.

Materials And Methods: Using the cost-minimization analysis direct medical cost of coronary endovascular treatment in patients with stable IHD during the "one-night" hospitalization was compared with the "classic" hospitalization.

Results: The most cost-effective strategy for hospitalization of patients for transcutaneous coronary intervention (TCI) with stenting was the "one-night" hospitalization.

[Cardiotoxicity of trastuzumab: mechanisms of development, diagnosis, treatment].

The review discusses mechanisms of trastuzumab cardio- toxicity. There are presented risk factors of development of the left ventricular dysfunction in treatment of a drug, among which the most important are the simultaneous administration of anthracycline antibiotics and the presence of associated cardiovascular diseases. There are discussed the features of cardiac management of patients receiving trastuzumab therapy that focuses on early detection of abnormalities of left ven- tricular function from the normality as well as measures aim- ing at preventing the occurrence of cardiac dysfunction and its treatment.
