OBJECTIVE: To investigate the expression of soluble intercellular adhesion molecule-1(sICAM-1) and CD11a/CD18 in coronary heart disease(CHD). METHODS: The sICAM-1 and CD11a/CD18 levels were measured by ELISA and flow cytlemetry in 76 CHD patients and 65 healthy subjects. RESULTS: The level of sICAM-1 and CD11a/CD18 were significantly higher in CHD patients than healthy subjects [SICAM-1(g/L):263.5 +/-66.2 compared with 205.9 +/-57.2, P<0.01; CD11a/CD18 (%):33.7 +/-6.4 compared with 19.3 +/-8.1, P<0.001]. They were also significantly higher in acute myocardial infarct and unstable angina than that of stable angina patients. There was correlation between sICAM-1 and CD11a/CD18(r=0.436, P<0.01). CONCLUSION: Elevated levels of sICAM-1 and CD11a/CD18 associated with unstable angina and myocardial infarction may indicate their significant role in the pathogenesis of acute coronary events.

Septic arthritis (SA) are rare in patients with burns, but delayed treatment can result in irreversible joint destruction. Early diagnosis and immediate treatment are necessary to prevent joint destruction. Robot training in patients with musculoskeletal diseases and burns, can improve joint range of motion (ROM), muscle strength, and lower extremity function.

Background: Ciliary neurotrophic factor (CNTF), mainly known for its neuroprotective properties, belongs to the IL-6 (interleukin-6) cytokine family. In contrast to IL-6, the effects of CNTF on the vasculature have not been explored. Here, we examined the role of CNTF in AngII (angiotensin II)-induced hypertension.

Background: Protein-truncating mutations in the titin gene are associated with increased risk of atrial fibrillation. However, little is known about the underlying pathophysiology.
Methods: We identified a heterozygous titin truncating variant (TTNtv) in a patient with unexplained early onset atrial fibrillation and normal ventricular function.

Background: Transcatheter heart valve (THV) underexpansion after transcatheter aortic valve replacement may be associated with worse outcomes. THV expansion can be assessed fluoroscopically using a pigtail for calibration; however, the accuracy of this technique specific to transcatheter aortic valve replacement is unknown. We assessed the accuracy and reproducibility of a novel fluoroscopic method to assess THV expansion using the THV commissural post for calibration.

Biosense Webster, Inc, Irvine, CA (J.M., T.S., S.F.-H.).
Background: Sequential application of radiofrequency with pulsed field (PF) ablation may increase lesion depth while preserving the advantages of PF. The study's aim was to determine lesion dimensions of sequential, colocalized radiofrequency and PF ablation.
Methods: A preclinical study using swine (n=4) performed lesions in the right/left ventricles.
