A new automated system for the analysis of nitrate via reduction with a high-pressure cadmium
column is described. Samples of urine, saliva, deproteinized plasma, gastric juice, and …

Nitrate metabolism was investigated in long-term metabolic studies in healthy young men.
Under conditions of constant low ingestion of nitrate (less than 180 mumol/day per subject), …

The preponderance of epidemiological evidence now points to a strong association between
chronic inflammation and cancers of several organs, including the gastrointestinal tract, …

Nitric oxide is a key participant in many physiological pathways; however, its reactivity gives
it the potential to cause considerable damage to cells and tissues in its vicinity. Nitric oxide …

Metabolic balance studies show that germfree and conventional Sprague-Dawley rats
synthesize nitrate. Equivalent results for germfree and conventional rats eliminate the microflora …

Microfabricated regular sieving structures hold great promise as an alternative to gels to
improve the speed and resolution of biomolecule separation. In contrast to disordered porous …

Background: The human intestine is host to an enormously complex, diverse, and vast microbial
community—the gut microbiota. The gut microbiome plays a profound role in metabolic …

Expansion microscopy (ExM) enables imaging of preserved specimens with nanoscale
precision on diffraction-limited instead of specialized super-resolution microscopes. ExM works …

Microphysiological systems (MPSs) are in vitro models that capture facets of in vivo organ
function through use of specialized culture microenvironments, including 3D matrices and …

Background: There is growing evidence that, when smoking habits are comparable, women
incur a higher risk of lung cancer than men. Because smokers are also at risk for bladder …
