Mapeamento vascular da monocoriônicas (MC) placentas gêmeas após o nascimento fornece um meio para a demonstração detalhada das conexões vasculares entre as circulações dos gêmeos. Desequilíbrio dessas conexões é pensado para jogar um papel crucial no desenvolvimento de complicações da geminação MC incluindo twin-to-twin síndrome de transfusão.

NF-kappaB Activation Precedes Increases in MRNA Encoding Neurokinin-1 Receptor, Proinflammatory Cytokines, and Adhesion Molecules in Dextran Sulfate Sodium-induced Colitis in Rats
Digestive Diseases and Sciences. Dec, 2005 | Pubmed ID: 16416193
Nuclear factor kappa B (NF-kappa B) plays a key role in initiating inflammation associated with colitis. A systematic study was conducted in the rat DSS colitis model to determine the temporal relationship between NF-kappa B activation and expression of substance P (SP), neurokinin-1 receptor (NK-1R), proinflammatory cytokines, and adhesion molecules. Rats were given 5% DSS in their water and sacrificed daily for 6 days. Colon tissue was collected for assessment of histological changes, NF-kappa B activation, myeloperoxidase (MPO) activity, and expression of NK-1R, SP, TNFalpha, IL-1beta, VCAM-1, ICAM-1, E-selectin, CINC-1, MIP-1alpha, and iNOS. NF-kappa B activation increased, biphasically, on Day 1 and again on Days 4-6. The mRNA levels for ICAM-1, CINC-1, IL-1beta, TNFalpha, VCAM-1, and NK-1R rose significantly (P < 0.05) by 2-4 days. Increased iNOS mRNA levels, MPO activity, and mucosal damage occurred on Day 6. These data demonstrate that NF-kappa B activation substantially precedes the onset of physical disease signs and active inflammation.
Dynamic Tracheal Occlusion Improves Lung Morphometrics and Function in the Fetal Lamb Model of Congenital Diaphragmatic Hernia
Journal of Pediatric Surgery. Jun, 2011 | Pubmed ID: 21683214
Congenital diaphragmatic hernia (CDH) is associated with significant neonatal morbidity and mortality. Although prenatal complete tracheal occlusion (cTO) causes hypoplastic CDH lungs to enlarge, improved lung function has not been demonstrated. Furthermore, cTO interferes with the dynamic pressure change and fluid flow associated with fetal breathing.
Surgical Innovation. Dec, 2011 | Pubmed ID: 21742664
Objective. This study aimed to assess the feasibility of a totally endoscopic enteral bypass using a self-orienting, dual ring, magnetic anastomosis system (MAGNAMOSIS) guided by a magnetic tracking system (3D METRIS). Materials and methods. In an anesthetized pig, 2 endoscopes were advanced, one each into the stomach and the colon. Both endoscopes were equipped with a MAGNAMOSIS ring secured with an endoscopic snare and a 3D METRIS within one working channel. The whole procedure was followed laparoscopically. The tracking system guided tips of endoscopes to a "rendez-vous" location between the colon and stomach. Results. MAGNAMOSIS magnets automatically joined in the correct configuration when guided to within 2 cm of each other. At necropsy, magnetic rings were secure without entrapment of excess bowel or mesentery. Conclusion. An endoscopic enteral bypass with magnetic anastomosis and magnetic tracking device was feasible. More accurate tracking and advanced techniques could enable endoscopic bypasses at multiple sites in the gastrointestinal tract.
Magnetic Mini-mover Procedure for Pectus Excavatum III: Safety and Efficacy in a Food and Drug Administration-sponsored Clinical Trial
Journal of Pediatric Surgery. Jan, 2012 | Pubmed ID: 22244409
The magnetic mini-mover procedure (3MP) uses magnetic force to gradually remodel pectus excavatum deformity. A magnet is implanted on the sternum and coupled with an external magnetic brace. Under Investigational Device Exemption and Institutional Review Board approval, we performed a pilot study of safety, probable efficacy, and cost-effectiveness of this new treatment of an orphan disease using an implantable pediatric device.
