The aetiology of intervertebral disc (IVD) degeneration remains poorly understood. Painful IVD degeneration is associated with an acidic intradiscal pH but the response of NP cells to this aberrant ...

Researchers from Tallinn University of Technology, Grete Raba, Signe Adamberg, and Kaarel Adamberg showed that an acidic environment enhances the production of butyric acid from apple pectin by faecal ...

A Donnan equilibrium causes an influx of chloride ions into the Escherichia coli periplasm when the bacterium finds itself in gastric fluid. The combination of low pH and high anion concentration ...

RECENTLY, we have encountered a series of patients with severe metabolic acidosis and serum pH values less than 7.0. Although such severe acidosis is widely regarded as leading rapidly to delirium and ...

When acidic components get into rain or other forms of precipitation, acid rain can make trees die. It won't hurt you to walk or swim in acid rain, but the particles that cause it may hurt your lungs ...

Soil pH is a measure of soil acidity or alkalinity. On the pH scale, a value of 7.0 is neutral, pH values less than 7.0 are acidic, and pH values greater than 7.0 are alkaline. Homeowners and ...

Parietal cells lining the human stomach produce hydrochloric acid concentrated to roughly 160 mmol/L, strong enough to pit ...

This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale ...
