Endometrioid carcinoma arising in pericecal endometriosis clinically mimicking Crohn's disease.

A case of endometrioid carcinoma arising in pericecal endometriosis that clinically and radiologically mimicked Crohn's disease is presented. After developing several complications of steroid therapy for presumed Crohn's disease, a 48-year-old woman developed intestinal obstruction and underwent a right hemicolectomy. A pericecal mass composed of endometriosis and endometrioid carcinoma and a locally metastatic ileal carcinoid tumor were resected.

Estimate of methane emissions from the U.S. natural gas industry.

Global methane emissions from the fossil fuel industries have been poorly quantified and, in many cases, emissions are not well-known even at the country level. Historically, methane emissions from the U.S.

Ergothioneine distribution in bovine and porcine ocular tissues.

Ergothioneine (ERT), is a low molecular weight, sulfur-containing antioxidant occurring in up to millimolar amounts in mammalian tissues. Using an improved HPLC assay, ERT levels have been measured and compared in bovine and porcine eyes and erythrocytes. The rank order of ERT levels in bovine ocular tissue was lens > retina = cornea > pigmented retinal epithelium (RPE) > aqueous humor (AQ) > vitreous humor (VIT) > sclera.

Protein levels in the vitreous of rats with streptozotocin-induced diabetes mellitus.

The vitreous is a neural extracellular space separated from the blood-vascular compartment by the blood-retinal barrier. Study of the appearance of serum proteins in this space have been carried out in rats with streptozotocin-induced diabetes mellitus, a condition associated with barrier dysfunction. A vitreous sampling technique that avoids contamination with surrounding tissue was employed.
