This study investigated changes in cognitive function in acute and delayed carbon monoxide (CO) poisoning groups with comprehensive neuropsychological tests at 1 month and 6 months after therapy. For this study, 11 patients with acute and 14 with delayed CO poisoning were recruited. The neuropsychological tests included psychomotor speed, visual-spatial ability, language, logical memory, working memory, and executive function. The results showed that patients with delayed neuropsychiatric syndrome (DNS) had poorer performance on neuropsychological tasks than did those with acute CO poisoning at the 1st month and reached almost the same level as the acute group on the neuropsychological tasks at the 6-month follow-up assessment. The DNS group had more significant progress on general cognitive function, psychomotor speed, and visual-spatial ability than did the acute group after continuous hyperbaric-oxygen therapy.

During the implantation process of cardiovascular implants, vascular damage caused by inflammation occurs, and the inflammatory process is accompanied by oxidative stress. Currently, carbon monoxide (CO) has been demonstrated to exhibit various biological effects including vasodilatation, antithrombotic, anti-inflammatory, apoptosis-inducing and antiproliferative properties. In this study, hemoglobin/epigallocatechin-3-gallate (EGCG) core-shell nanoparticle-containing coating on stainless steel was prepared for CO loading and inflammation modulation.

In the ancient microbial Wood-Ljungdahl pathway, carbon dioxide (CO) is fixed in a multistep process that ends with acetyl-coenzyme A (acetyl-CoA) synthesis at the bifunctional carbon monoxide dehydrogenase/acetyl-CoA synthase complex (CODH/ACS). In this work, we present structural snapshots of the CODH/ACS from the gas-converting acetogen , characterizing the molecular choreography of the overall reaction, including electron transfer to the CODH for CO reduction, methyl transfer from the corrinoid iron-sulfur protein (CoFeSP) partner to the ACS active site, and acetyl-CoA production. Unlike CODH, the multidomain ACS undergoes large conformational changes to form an internal connection to the CODH active site, accommodate the CoFeSP for methyl transfer, and protect the reaction intermediates.

Aim: To evaluate the correlation between semi-quantitative analyses and visual scores of pulmonary perfusion Single Photon Emission Computed Tomography (SPECT)/ Computed Tomography (CT) imaging and pulmonary function test parameters (PFTs) in patients with interstitial lung diseases (ILDs).
Materials And Methods: This retrospective study included 35 patients with ILDs from China-Japan Friendship Hospital between January 2020 and December 2022. All patients underwent pulmonary perfusion SPECT/CT imaging and a pulmonary function test.

Diverse bacteria and archaea use atmospheric CO as an energy source for long-term survival. Bacteria use [MoCu]-CO dehydrogenases (Mo-CODH) to convert atmospheric CO to carbon dioxide, transferring the obtained electrons to the aerobic respiratory chain. However, it is unknown how these enzymes oxidize CO at low concentrations and interact with the respiratory chain.
