Torres Filho IP, Terner J, Pittman RN, Proffitt E, Ward KR. Measurement of hemoglobin oxygen saturation using Raman microspectroscopy and 532-nm excitation. J Appl Physiol 104: 1809–1817, 2008. First published March 27, 2008; doi:10.1152/japplphysiol.00025.2008.— The resonant Raman enhancement of hemoglobin (Hb) in the Q band region allows simultaneous identification of oxyand deoxy-Hb. The hem...

The manuscript discusses SO2 changes observed by OMI and links them to the national regulations of SO2 emissions. The paper demonstrates again the usefulness of satellite monitoring of air pollutions in China, the world largest SO2 emitter. It is shown that major changes in OMI records are linked to the emission reduction legislation. In general, the paper is well written, although some places ...

The use of biomass indoor Honai (traditional house) in Wamena have been conducted for several decades and become a traditional habit of Honai occupants. Since air temperature at night in Wamena Regency is cold the inhabitans burn the Kasuari woods to warm their body. As a result, they continuously inhale the Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2) and some contaminated air in Honai room...

OBJECTIVE To assess the health risks associated with exposure to particulate matter (PM10), sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO) and ozone (O3). DESIGN The study is an ecological study that used the year 2014 hourly ambient pollution data. SETTING The study was conducted in an industrial area located in Pretoria West, South Africa. The area accommodates a coal...

Among the tuberculosis (TB) vaccine candidates, SO2 is the prototype of the first live-attenuated vaccine that recently entered into clinical trials. To investigate the capacity of SO2 to stimulate an appropriate immune response in vitro within a human immunological context, a comparative analysis of the effects promoted by SO2, the current Bacille Calmette-Guerin (BCG) vaccine and Mycobacteriu...

BACKGROUND To investigate the correlation between cerebral (SO2-transcranial), retinal arterial (SaO2-retinal) and venous (SvO2-retinal) oxygen saturation as measured by near-infrared spectroscopy (NIRS) and retinal oximetry respectively. METHODS Paired retinal and cerebral oxygen saturation measurements were performed in healthy volunteers. Arterial and venous retinal oxygen saturation and d...

[1] On 5 April 2005, during the East Asian Study of Tropospheric Aerosols: An International Regional Experiment (EAST-AIRE) aircraft campaign, heavy loadings of SO2 (20 ppb near ground, 1–3 ppb at 2 km altitude) and dust with aerosol optical depth of 1 were measured over Shenyang, an industrialized city 600 km NE of Beijing. In this study, Ozone Monitoring Instrument (OMI) and MODIS satellite s...

BACKGROUND We aimed to explore the role of endogenous sulfur dioxide (SO2) in pulmonary vascular collagen remodeling induced by monocrotaline and its mechanisms. METHODS AND RESULTS A rat model of monocrotaline-induced pulmonary vascular collagen remodeling was developed and administered with l-aspartate-β-hydroxamate or SO2 donor. The morphology of small pulmonary arteries and collagen metab...
