Purinergic Signaling in Pulmonary Inflammation
Purine nucleotides and nucleosides are at the center of biologic reactions. In particular, adenosine triphosphate (ATP) is the fundamental energy currency of cellular activity and adenosine has been demonstrated to play essential roles in human ...

Altered chemomechanical coupling causes impaired motility of the kinesin-4 motors KIF27 and KIF7. [PDF]
Kinesin-4 motors play important roles in cell division, microtubule organization, and signaling. Understanding how motors perform their functions requires an understanding of their mechanochemical and motility properties.

36 degree step size of proton-driven c-ring rotation in FoF1-ATP synthase [PDF]
Synthesis of the biological "energy currency molecule" adenosine triphosphate ATP is accomplished by FoF1-ATP synthase. In the plasma membrane of Escherichia coli, proton-driven rotation of a ring of 10 c subunits in the Fo motor powers catalysis in the ...

Phosphorylation of Myosin by Adenosine Triphosphate [PDF]
THE study of the interaction between actomyosin and adenosine triphosphate has hitherto given evidence of physical changes in the protein and of its enzymic activity. Very little was known, however, of chemical changes in the protein molecule accompanying the physical effects.

Zr(IV) can form phosphate and Zr(IV) (–PO32−–Zr4+–) complex owing to the high affinity between Zr(IV) with phosphate. Zr(IV) can induce the aggregation of gold nanoparticles (AuNPs), while adenosine triphosphate(ATP) can prevent Zr(IV)-induced ...

Inhibition of Intestinal Thiamin Transport in Rat Model of Sepsis. [PDF]
ObjectivesThiamin deficiency is highly prevalent in patients with sepsis, but the mechanism by which sepsis induces thiamin deficiency is unknown. This study aimed to determine the influence of various severity of sepsis on carrier-mediated intestinal ...

Automatic instrument for chemical processing to detect microorganism in biological samples by measuring light reactions [PDF]
An automated apparatus is reported for sequentially assaying urine samples for the presence of bacterial adenosine triphosphate (ATP) that comprises a rotary table which carries a plurality of sample containing vials and automatically dispenses fluid ...
