Results and Complications After Single-Stage Repair of Aortopulmonary Window and Interrupted Aortic Arch in a 32-Week Preterm and a Full-Term Neonate.

BACKGROUND An aortopulmonary window (APW) is an uncommon congenital defect of the septation between the ascending aorta and pulmonary trunk. The combination of APW and interrupted aortic arch (IAA) is even rarer, with the hallmark characteristics of high peri-operative mortality and postoperative obstruction of the aortic arch, pulmonary artery, and left main bronchus. These complications often need re-interventions.

Optical Coherence Tomography in a 9-Year-Old Kawasaki Disease Patient with Giant Coronary Artery Aneurysms and Acute Myocardial Infarction.

BACKGROUND Kawasaki disease (KD), a systemic vasculitis, affects children aged <5 years and is the leading acquired cardiovascular disease in developed countries. Although intravenous immunoglobulin is an effective treatment for KD and decreases the rate of cardiovascular complications, some patients still develop coronary sequelae, including coronary aneurysms and myocardial infarction. CASE REPORT A 9-year-old boy was diagnosed with KD at the age of 6 years.

Vitrification successfully preserves hepatocyte spheroids.

This is the first report on low-temperature preservation of self-assembled cell aggregates by vitrification, which is both a time- and cost-effective technology. We developed an effective protocol for vitrification (ice-free cryopreservation) of hepatocyte spheroids that employs rapid stepwise exposure to cryoprotectants (10.5 min) at room temperature and direct immersion into liquid nitrogen (-196 degrees C).

The role of cytokines in activation of coagulation and fibrinolysis in dengue shock syndrome.

In a prospective clinical study of 50 patients with Dengue Shock Syndrome (DSS), we investigated the association of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), IL-1 receptor antagonist (IL-1Ra), and IL-6 with activation markers of coagulation (F1+2 and TATc) and fibrinolysis (t-PA, PAPc, and D-dimer). We found that TNF-alpha, IL-1beta and Il-1Ra, but not IL-6, concentrations were elevated in the circulation during the early stage of infection and at discharge from hospital. TNF-alpha was significantly associated with D-dimer, an activation marker of fibrinolysis (p < 0.
