A strategy is devised to screen molecules based on their radiative efficiency. The methodology should be useful as one additional constraint when determining the best molecule to use for an industrial application. The strategy is based on the results of a recent study where we examined molecular properties of global warming molecules using ab initio electronic structure methods to determine whi...

BACKGROUND Despite maximal ventilatory support, many patients die from hypoxia in the setting of potentially reversible pulmonary failure. There remains a pressing need for additional pulmonary supportive care measures, especially techniques that do not require systemic anticoagulation. The objective of our experiments was to determine whether systemic oxygenation could be increased in a large ...

ConspectusFuture medicine is primarily aiming at the development of novel approaches for an early diagnosis diseases and a personalized therapy patients. For achieving these objectives, key role played by medical imaging. Among available noninvasive imaging techniques, Fluorine-19 (19F) Magnetic Resonance Imaging (MRI) emerging as powerful quantitative detection modality clinical use both molec...

This study was undertaken to determine the effects of superimposing incremental levels of positive end-expiratory pressure (PEEP) during partial liquid ventilation (PLV) on gas exchange, respiratory mechanics and morphological changes in experimental acute lung injury (ALI). In a prospective trial, six pigs weighing 30+/-5 kg (mean+/-SD) were tracheotomized, submitted to pressure-controlled mec...

Cancer is the collective group of diseases distinguished by uninhibited growth and spread of abnormal cells. It often results in death if the spread is not controlled. Most cancers are treated by surgery, radiation, chemotherapy, hormones, or immunotherapy. However, currently there are many issues with these forms of treatment, namely the lack of ability to consistently remove the entire tumor ...

On an evolutionary time scale, liquid ventilation is not new. Land-dwelling vertebrates derived from fish 350 million years ago, and fish continue to breathe through a liquid medium. However, the ability to sustain mammalian respiration artificially by a liquid ventilation technique is generally accredited to work in the early 1960s, where mice were kept alive breathing hyperbaric salt solution...

Eighty percent of lung cancers originate as subtle premalignant changes in the airway mucosal epithelial layer of bronchi and alveoli, which evolve and penetrate deeper into the parenchyma. Liquid-ventilation, with perfluorocarbons (PFC) was first demonstrated in rodents in 1966 then subsequently applied as lipid-encapsulated PFC emulsions to improve pulmonary function in neonatal infants suffe...

Background—Emulsified perfluorocarbons (PFCs) are preferentially phagocytized by monocytes/macrophages and are readily detected by 19 F MRI. This study tests the hypothesis that 19 F MRI can be used to quantitate pulmonary inflammation by tracking of infiltrating PFC-loaded monocytes. Methods and Results—Pneumonia was induced in mice by intratracheal instillation of lipopolysaccharides (LPS) fo...

PREFACE The U. S. Environmental Protection Agency (EPA) initiated preparation of this Protocol as part of its commitment to assist the PFC Emissions Reduction/Climate Partnership for the Semiconductor Industry (the Partnership) to achieve its voluntary fluorinated greenhouse gas (F-GHG) emission reduction and reporting goals. F-GHGs include the most powerful and often persistent greenhouse gase...
