Suprahepatic Cava Thrombus Due to Wilms Tumor: Technique Without Cardiopulmonary Bypass.

Wilms tumor is a frequent malignant neoplasia in pediatric population. Extension to the inferior vena cava is a complication that occurs in approximately 4%-15% of cases. Surgical techniques derived from the field of adult transplant surgery allow the resection of the tumor with its thrombus extension.

Brain specific kinase-1 BRSK1/SAD-B associates with lipid rafts: modulation of kinase activity by lipid environment.

Brain specific kinases 1 and 2 (BRSK1/2, also named SAD kinases) are serine-threonine kinases specifically expressed in the brain, and activated by LKB1-mediated phosphorylation of a threonine residue at their T-loop (Thr189/174 in human BRSK1/2). BRSKs are crucial for establishing neuronal polarity, and BRSK1 has also been shown to regulate neurotransmitter release presynaptically. How BRSK1 exerts this latter function is unknown, since its substrates at the synaptic terminal and the mechanisms modulating its activity remain to be described.
