STUDY OBJECTIVE To evaluate the efficacy of negative pressure ventilation (NPV) in avoiding or reducing apneas and related hypoxemia and respiratory acidosis during laser therapy (LT) of endobronchial lesions. DESIGN A prospective, controlled, randomized study. SETTING An operating theater of a respiratory endoscopy and laser therapy unit. POPULATION AND INTERVENTION: Twenty-seven consecuti...
The association between spectral reflectance and canopy processes remains challenging for quantifying large-scale canopy phenological cycles in tropical forests. In this study, we used a tower-mounted hyperspectral camera in an eastern Amazon forest to assess how canopy spectral signals of three species are linked with phenological processes in the 2012 dry season. We explored different approac...
The genome sequence of a Polish isolate of Agrotis segetum nucleopolyhedrovirus (AgseNPV-A) was determined and analysed. The circular genome is composed of 147,544 bp and has a G+C content of 45.7 mol%. It contains 153 putative, non-overlapping open reading frames (ORFs) encoding predicted proteins of more than 50 aa, together making up 89.8 % of the genome. The remaining 10.2 % of the DNA cons...
Pulmonary rehabilitation (PR) brings benefits to patients with chronic obstructive pulmonary disease (COPD). Negative pressure ventilation (NPV) increases ventilation and decreases hyperinflation as well as breathing work in COPD. We evaluated the long-term effects of a hospital-based PR program coupled with NPV support in patients with COPD on clinical outcomes.One hundred twenty-nine patients...
OBJECTIVES To assess whether MRI can exclude axillary lymph node metastasis, potentially replacing sentinel lymph node biopsy (SLNB), and consequently eliminating the risk of SLNB-associated morbidity. METHODS PubMed, Cochrane, Medline and Embase databases were searched for relevant publications up to July 2014. Studies were selected based on predefined inclusion and exclusion criteria and in...
within 21 days. The likelihood ratio for a negative result [(1 sensitivity)/specificity] was 0.59 for birth within 7 days, 0.68 for birth within 14 days, and 0.53 for birth within 21 days. The data in Table 1 are similar to those obtained in previous studies using the ELISA-based assay. Joffe et al. (1 ) reported a NPV of 99.6% and a PPV of 9.1% for 243 patients who delivered within 7 days with...
In a consecutive series of 26 previously operated patients diagnosed with cerebral glioma, magnetic resonance spectroscopy (MRS), 2-((18)F) fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET), and perfusion MRI (MRP), were performed at follow-up to distinguish recurrence from radiation necrosis, and to identify tumour upgrading. Discrepancy between techniques was observed in 9 cases...
در این تحقیق قدرت بیمارگری سه ویروس Spodoptera littoralis NPV، Helicoverpa armigera NPV و Spodoptera litura NPV در سه غلظت مختلف 10۲×6، 104×6 و ۱۰۶×۶ OB در میلیلیتر روی لاروهای ۵ روزه کرم برگخوار مصری پنبه (Spodoptera littoralis) در دمای ۲5 درجه سلسیوس روی غذای مصنوعی بررسی شد. بیشترین طول دوره لاروی با 19.7 روز مربوط به ویروس H. armigera در غلظت ۱۰۴×6 OB در میلیلیتر بود که با بقیه تیمارها اخ...
