mediators during an immune response. Cytokines and other inflammatory mediators act on local blood vessels causing dilation of blood vessels and an increase in vascular permeability. Blood flow is increased and there is an increase in the leakage of fluid and proteins from blood vessels into tissues. This increase in blood flow and vascular permeability is produced so that immune cells can leave blood vessels‚ enter blood cells and fight infection. During the innate immune response‚ pathogen-associated

If the body temperature does not rise immediately after this‚ then a second function begins. The brain will signal the blood vessels near the skin to constrict or narrow in diameter. This occurs so the heat deep in the muscles is conserved. Since the vessels are now smaller in diameter‚ less blood is needed to fill them. Since less blood is needed through the vessels‚ the heart begins to slow. If the body remains in this slowed state‚ hypothermia could result. Hypothermia is the condition in

Merox process for removal of mercaptans from LPG and light naphtha It is a two-step process. In the first step‚ the feedstock LPG or light naphtha is contacted in the trayed extractor vessel with an aqueous caustic solution containing UOP’s proprietary liquid catalyst. The caustic solution reacts with mercaptans(RSH) and extracts them. The reaction that takes place in the extractor is: 2RSH + 2 NaOH → 2NaSR + 2 H2O The second step is referred to as regeneration and it involves heating and oxidizing
