3D Bioprinting Pediatric Trachea
Tracheal failures due to trauma, disease, or congenital anomalies, if not fatal, severely decrease quality of life. While small defects can be resolved surgically with resection and anastomosis, defects exceeding a critical length of trachea require graft material. This critical length varies from …

A Study of the Action of Prostaglandin F2a on the Guinea-Pig Isolated Trachea
… F2a (PGF2a)1 on guinea-pig isolated trachea has been studied. Special emphasis was placed on considerations of the possible beta-adrenergic blocking activities of this essential fatty-acid derivative. | Experiments were performed using a 20 ml tissue bath and a modified …

Radiologic, Histologic and Functional Evaluation after Implantation of Cultured Trachea Allograft : in vivo study
BACKGROUND: Commonly known as praying about how hard of a reconstruction, cartilage grafts, anastomosis country EP and the glass plate or Sophie. The sum of the areas of narrowing it after removing the door if possible, all the way to the ideal treatment in patients with anastomosis hard liquor, …

Radiologic, Histologic and Functional Analysis after Transplantation of Autologous Cultured Chondrocytes into Trachea and Vocal Fold
Reconstruction of tracheal defects is one of the most difficult procedures in head and neck surgery. To date, various reconstructing techniques have been used with no consensus on the best approach. This study investigated the feasibility of using a fibrin/hyaluronic acid (HA) composite gel with …

Development of a Software Application to Extract the Features of Normal Respiratory Sounds from the Lungs and the Trachea
… of respiratory sound signals from the lungs and trachea of healthy persons. The efficacy of the program was evaluated by the verification of the important features of the sound signals from the left and right lungs and the trachea such as 1) right and left lung symmetry and 2) dissimilarity …

Characterization of the airway epithelial bioelectric mechanisms associated with the effects of epithelium-derived relaxing factor in guinea pig-isolated trachea
… elevated serosal or mucosal tonicity, guinea-pig tracheal epithelium releases the non-nitric oxide, non-prostanoid, epithelium-derived relaxing factor (EpDRF), which subsequently diffuses to the underlying airway smooth muscle to initiate relaxation. Hypertonicity-induced smooth muscle relaxation …

Assessment of fetoscopic tracheal occlusion using ultrasound images in phantom study
… with CDH may be improved by fetal endoscopic tracheal occlusion (FETO). During pregnancy, fetal lungs secrete fluid into the amniotic cavity through the airways. FETO is a minimally invasive therapy which objective is to stimulate pulmonary growth. Through a small incision in the skin a very …

Studies on the role of the autonomic nervous system in airway hyperreactivity.
… vitro in both normal and sensitized guinea-pig trachea, suggesting that the pre-junctional K+ - channels involved in modulating vagal tone are functioning normally in sensitized tissues. The sensitization process however, may alter post-junctional K+ - channel behaviour since cromakalim …

Efeito relaxante de derivados N-sulfonilidrazônicos do rolipram em traqueia de cobaia : investigação do mecanismo de ação do LASSBio-1846
… on physiological conditions, the guinea - pig trachea model was selected. Thus, the present study aimed to assess a possible relaxant action of a new series from rolipram, a PDE4 inhibitor, as well as elucidate the mechanism of action of the more potent derivative. Therefore, from guinea - pigs …

Characteristics of sperm binding to the mouse oviduct
… was determined using the isthmus, ampulla, and trachea (n = 4). The results showed no difference in binding between isthmus and trachea (P > 0.05) but binding to the ampulla was less than the isthmus (P < 0.05). Capacitation status also affected sperm binding (n = 3). The number of sperm from …

Quantitative Analyse der Aspiration bei trachealer Intubation an einem physikalischen Modell
Der Cuff eines endotracheal plazierten Tubus' spielt in bezug auf die Patho-genese einer VAP (Ventilator-associated-pneumonia) eine zentrale Rolle. Seine Falten sind es, die den Keimen als Weg in Richtung Lunge dienen, wo sie sich einnisten und für den Menschen schädlich werden können. <br>Diese …
