BACKGROUND Analysis of myocardial blush grade (MBG) and coronary flow velocity pattern has been used to obtain direct or indirect information about microvascular damage and reperfusion injury after percutaneous transluminal coronary angiography for acute myocardial infarction. OBJECTIVE To evaluate the relation between coronary blood flow velocity pattern and MBG immediately after angioplasty...

Background: Analysis of myocardial blush grade (MBG) and coronary flow velocity pattern has been used to obtain direct or indirect information about microvascular damage and reperfusion injury after percutaneous transluminal coronary angiography for acute myocardial infarction. Objective: To evaluate the relation between coronary blood flow velocity pattern and MBG immediately after angioplasty...

An extraordinary diversity of amino acid sequences in the peptide-binding region (PBR) of human leukocyte antigen [HLA; human major histocompatibility complex (MHC)] molecules has been maintained by balancing selection. The process of accumulation of amino acid diversity in the PBR for six HLA genes (HLA-A, B, C, DRB1, DQB1, and DPB1) shows that the number of amino acid substitutions in the PBR...

It is known that muscle activation patterns are changed when the force requirements of a task are increased (e.g., moving a heavier inertial load) or when the available muscle force is reduced (e.g., by inducing muscle fatigue). It is not known whether this is true when the torque-producing capability of a muscle is altered. Eight neurologically healthy subjects performed flexion and extension ...

OBJECTIVE To study the prognostic value of left ventricular (LV) diastolic function and its relation with autonomic balance expressed by heart rate variability (HRV) in patients after a first acute myocardial infarction. DESIGN The study population consisted of 64 consecutive patients with first acute myocardial infarction and 31 control subjects. Long and short term HRV indices were evaluate...
