'Ming Cai' 'Heping Cai'] Background Recent evidence increasingly suggests key roles for the tricarboxylic acid cycle and fatty acid metabolism in tumor progression and metastasis. Aconitase 2 (ACO2) is a component of the tricarboxylic acid cycle and represents a key cellular metabolic hub that promotes de novo fatty…

Mitochondrial dysfunction during lung ischemia-reperfusion injury (LIRI) contributes to organ dysfunction. Aconitase-2 (ACO2), by enhancing the mitochondrial tricarboxylic acid (TCA) cycle in pulmonary vascular endothelial cells (PVECs), plays a critical role in maintaining cellular energy metabolic homeostasis.…

A fundamental objective of hemodynamic resuscitation is to reverse tissue hypoperfusion and prevent progression to multiorgan failure and death. Conventional tools such as clinical examination, lactate levels, and central or mixed venous oxygen saturation (ScvO₂ and SvO₂, respectively) have intrinsic limitations. These…

According to Fick’s principle, the total uptake of (or release of) a substance by tissues is the product of blood flow and the difference between the arterial and the venous concentration of the substance. Therefore, the mixed or central venous minus arterial CO2 content difference depends on cardiac output (CO).…

As an expression on Fick’s principle, the reduction in cardiac output is associated with a parallel increase in both mixed venoarterial CO2 content difference (Cmv-aCO2) and arterial-mixed venous oxygen content difference (Ca-mvO2). Nevertheless, disproportioned elevations in Cmv-aCO2 compared to those of Ca-mvO2 ensue…

Technological and medical advances over the past few decades epitomize human capabilities. However, the increased life expectancies and concomitant land-use changes have significantly contributed to the release of ~830 gigatons of CO2 into the atmosphere over the last three decades, an amount comparable to the prior…

We report a highly efficient approach to carbon capture and sequestration via the water catalyzed conversion of basic oxygen steel (BOS) slag and CO2 into CaCO3 and volumetrically stable aggregate for road construction using the Zero-Air-Pollution-Carbon-Capture-Capsule (ZAP-C3) units. The overall transformation is…

Electrochemically mediated carbon capture (EMCC) offers a promising alternative to thermochemical carbon capture methods due to its higher energy efficiency and the ability to operate under standard conditions. Graphitic electrodes functionalized with redox-active organic (RAO) capture agents offer a unique opportunity…

We present two novel experimental techniques designed to quantify the contributions of nucleophilicity-swing and pH-swing mechanisms to carbon capture in the electrochemical aqueous quinone-based CO2 capture process. Through thermodynamic analysis, we elucidate the intricate interplay between these two mechanisms, and…

The mechanism of Supercapacitive Swing Adsorption (SSA) has been investigated by pH measurements and acid-base titrations of water-extracted, charged activated carbon electrodes at voltage windows varying from 0-0.5V and 0-1.4V. 15%CO2/85%N2 mixtures and pure N2 were used as feed gases. Deionized water extracts from…

Carbon dioxide capture is an important greenhouse gas mitigation technology that can help limit climate change. The design of improved capture materials requires a detailed understanding of the mechanisms by which carbon dioxide is bound. Nuclear magnetic resonance (NMR) spectroscopy methods have emerged as a powerful…

17O NMR spectroscopy is emerging as a powerful probe of the chemistry of CO2 capture and storage materials. However, the technique is currently underutilised, owing to (i) challenging spectral interpretation of quadrupolar nuclei (I = 5/2), especially when multiple oxygen environments are present, and (ii) the need for…
