Anatomical context of RP13-122B23.3

  • In this study, we demonstrate that COBRA1 mRNA was differentially expressed in breast cancer cell lines by semi-quantitative reverse transcription-polymerase chain PCR (RT-PCR) [11].
  • Treatment of human breast cancer and brain tumor cells with COBRA-1 caused destruction of microtubule organization and apoptosis [12].
  • RESULTS: Surgeons at 3 institutions placed the Cobra catheter in patients undergoing coronary artery bypass grafting (n = 13), valve (n = 3), and combined valve-bypass (n = 4) operations [3].
  • Getting the tube in the oesophagus and oxygen in the trachea: preliminary results with the new supraglottic device (Cobra) in 28 anaesthetised patients [13].
  • OBJECTIVES: In animals the Cardeon Cobra catheter (Cardeon Corp, Cupertino, Calif) allows independent control of aortic arch and descending aortic temperatures and profoundly reduces cerebral embolization during bypass [3].
 

Associations of RP13-122B23.3 with chemical compounds

  • 1. Cobra cystatin strongly inhibits cysteine proteinases of the papain family, but not calpain [14].
  • We describe a functional assay which is based on the interaction of factor B from various animal species with Cobra Venom Factor, the snake C3b-analog [15].
  • Our aim was to evaluate the performance of the Cobra Perilaryngeal Airway in a cohort study and in a randomised, controlled, crossover comparison study with the Classic Laryngeal Mask Airway [16].
  • The sensitivity and specificity of the four ELISAs were tested with purified antigens and EDTA-plasma or Cobra venom factor-activated EGTA-plasma samples as a source of C3a and C5a [17].
  • Complete amino acid sequence of an acidic, cardiotoxic phospholipase A2 from the venom of Ophiophagus hannah (King Cobra): a novel cobra venom enzyme with "pancreatic loop" [18].
