Diffuse brain SPECT abnormalities have been described in most systemic diseases, such as systemic lupus erythematosus [33, 34]; hypothyroidism [35]; after chemotherapy [16, 36], carbon monoxide poisoning [37] or manganese toxicity [38]; and in cocaine [39] or alcohol abuse [17].

Our research group suggested that the pathway HO-1/carbon monoxide has a significant protective effect when there is injury caused by the TcdA,including decreased neutrophilic infiltrate in the mucosa.

We considered five pollutants [PM10, ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2)] in single- and multipollutant analyses.
1,4-Bisdesoxycyadox (BDCYX), cyadox-1-monoxide (CYX-1-O) and quinoxaline-2-carboxylic acid (QCA), three main metabolites of cyadox, were synthesized by College of Science, China Agricultural University.
The evolved volatiles include carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), water (H2O), nitrogen dioxide (NO2), sulfur dioxide (SO2), hydrocarbon, methanol, formic acid, phenols, aromatic compounds, etc.
Each monitoring station measures the gaseous pollutants [nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), and sulfur dioxide (SO2) and particulate matter (PM) hourly.
They found that EC was significantly associated with CVD mortality, but they also found similar associations with nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and PM2.5.
In addition to PM, workers in foundries may have additional exposures, including heat, polycyclic aromatic hydrocarbons [ 30], carbon monoxide [ 31], and non-ionizing radiations [ 32], which could also contribute to generate oxidative stress.
L-lactic acidosis may be secondary to congenital or acquired mitochondrial respiratory chain dysfunction, including tissue hypoxia [ 59], carbon monoxide poisoning [ 60], cyanide poisoning [ 61] and drugs such as linezolid, phenformin, and stavudine [ 62– 62].
