This is the solution to a case we presented recently. You may review the case here. The patient had complained of dyspnea, and an abnormal electrolyte panel revealed a decreased bicarbonate level of ...

A molecular movie has captured in detail the process of an anion transported across the cell membrane by a light-fuelled protein pump. Researchers have unravelled the mystery of how light energy ...

To grab hold of an anion, an organic host molecule usually uses strong hydrogen-bond donors, such as N–H bonds or C–H bonds adjacent to a cationic center. Now, chemists at Indiana University have ...

Many bacteria and unicellular algae have light-driven pumps in their cell membranes: proteins that change shape when exposed to photons such that they can transport charged atoms in or out of the cell ...

The cation sodium and the anion chloride are normally found in most foods together as sodium chloride, also termed salt. For this reason, this report presents data on the requirements for and the ...

Internal acid–base homeostasis is fundamental for maintaining life. Accurate and timely interpretation of an acid–base disorder can be lifesaving, but the establishment of a correct diagnosis may be ...
