Human Salivary Gland Adenocarcinoma
Adenocarcinoma of the human salivary gland exhibits orange-stained nuclei on a green background of cellular components when stained with propidium diiodide and FITC.
Adenocarcinoma is a cancer of an epithelium that originates in glandular tissue. Epithelial tissue includes, but is not limited to, the surface layer of skin, glands and a variety of other tissue that lines the cavities and organs of the body. Epithelium can be derived embryologically from ectoderm, endoderm or mesoderm.

Rise in Allergies Linked to War on Bacteria
“Allergic diseases have reached pandemic levels,” begins David Artis’s new paper in Nature Medicine. Artis goes on to say that, while everyone knows allergies are caused by a combination of factors involving both nature and nurture, that knowledge doesn’t help us identify what is culpable — it is not at all clear exactly what is involved, or how the relevant players promote allergic responses.
There is some evidence that one of the causes lies within our guts. Epidemiological studies have linked changes in the species present in commensal bacteria — the trillions of microorganisms that reside in our colon — to the development of allergic diseases. (Typically, somewhere between 1,000 and 15,000 different bacterial species inhabit our guts.) And immunologists know that signaling molecules produced by some immune cells mediate allergic inflammation.
