H&E stain, HE stain or hematoxylin and eosin stain is a popular staining method in histology. It is the most widely used stain in medical diagnosis; for example when a pathologist looks at a biopsy of a suspected cancer, the histological section is likely to be stained with H&E and termed H&E section, H+E section, or HE section.

The staining method involves application of hemalum, which is a complex formed from aluminum ions and oxidized haematoxylin. This colors nuclei of cells (and a few other objects, such as keratohyalin granules) blue. The nuclear staining is followed by counterstaining with an aqueous or alcoholic solution of eosin Y, which colors other, eosinophilic structures in various shades of red, pink and orange.

The staining of nuclei by hemalum does not require the presence of DNA and is probably due to binding of the dye-metal complex to arginine-rich basic nucleoproteins such as histones. The mechanism is different from that of nuclear staining by basic (cationic) dyes such as thionine or toluidine blue. Staining by basic dyes is prevented by chemical or enzymatic extraction of nucleic acids. Such extractions do not prevent staining of nuclei by hemalum.

Ishe Smith was a strong prospect early in his career, primarily as a good counter-puncher with excellent defensive skills. He won his first fourteen fights prior to the Contender, facing generally strong opposition early in his career. He faced future fellow Contender Alfonso Gomez in his fourth pro fight(Alfonso's second pro fight) and won via a controversial unanimous decision(due to a low blow penalty against Gomez that was poorly called) in a four round fight back in 2001. He also beat another future Contender Season 2 alum, Norberto Bravo by unanimous decision later in the same year. Most notably, he dominated a fellow hot prospect at the time, David "King" Estrada, beating him by a wide unanimous decision in 2003.

There was little to separate the two men in terms of scoring the fight, but Smith won by scores of 116-111, 117-110, and 114-113. He cried in joy following the match.
