Background: Arterial stiffness is associated with increased risk for cardiovascular disease. The purpose of this study is to investigate the arterial stiffness and myocardial deformation in patients with poorly controlled diabetes mellitus type 2 before and after glycemic control by optimal medication. Methods: In 50 patients with uncontrolled type 2 diabetes(age:52±10years)and 25 controls of similar age and sex and no atherosclerotic risk factors we measured at baseline and 6 months after glycemic control a) carotid-femoral pulse wave velocity(PWVc m/sec-Complior SP ALAM),central systolic blood pressure(cSBP -mmHg),augmentation index(AI%), of the aortic pulse wave(ArteriographTensioMed) b)S',E'(m/sec)andE'/A'of mitral annulus by Tissue Doppler c)LV longitudinal strain(GLS-%),systolic(LongSr-l/sec)and diastolic(LongSrE-l/sec)strain rate, twisting(Tw-deg),peak twisting(Tw)and untwisting(unTw-deg/sec)velocity using speckle tracking echocardiography...

Since N-acetylneuraminic acid (NANA) in cell membrane glucocalyx mediates or modulates a variety of actions, such as mediator release, we examined a possible modulating role of this amino sugar in histamine release from human basophil leukocytes. Removal of NANA from the cell membrane by the enzyme neuraminidase caused a dose-dependent histamine release. Removal of smaller amounts of NANA enhanced histamine release induced by anti-IgE, Concanavalin A and the calcium ionophore A23187, and reduced the interval between addition of antigen and initiation of histamine release...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
