OBJECTIVE: To analyze and update information about surfactant therapy replacement in newborns with lung diseases. SOURCES: Literature review, including textbooks, meta-analyses, prospective, randomized controlled trials, retrospective assessments and case studies. Literature was reviewed based on the authors clinical and scientific experience regarding surfactant replacement therapy in neonatal...

Pneumonia is an important cause of respiratory failure, and is associated with increased alveolar permeability leading to pulmonary oedema, haemorrhage and atelectasis [1, 2]. The pathophysiological changes in pneumonia include hypoxaemia, decreased functional residual capacity (fRC), decreased total lung capacity (TLC), decreased lung compliance, and a diminished surfactant system [3-5]. As ea...

Abstract A considerable number of research works focus on the positive influence cellulose properties polymer-based composites and their wide range application possibilities. The present work is focused synthesis novel bio-based polyurethane (bio-PU) filled with powdered (microcellulose, MC) in an amount 5 wt.%. Bio-PU were synthesized via a non-solvent prepolymer method. First, was from diisoc...

A cationic surfactant ion-selective field-effect transistor (cationic surfactant-ISFET) has been developed based on the tetraphenylborate derivative known as sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate. The cationic surfactant-ISFET shows an almost Nernstian response to tetradecyldimethylbenzylammonium chloride (Zephiramine) over a concentration range between 1.0 x 10(-6) M and 1.0 x ...
