The distribution and intensity of alkaline phosphatase deposition in 54 patients with dermatomyositis-polymyositis (PM-DM) was analyzed by the enzyme histochemical method. Increased enzyme reactivity of endomysial capillaries was found in 28% of patients, equally distributed between adult onset PM (Group I) and PM-DM with overlap in other connective tissue(More)
We have studied the acute changes (up to 30 days) in the expression of epidermal growth factor (EGF) and its receptor (EGFr) in the kidneys of adult male Wistar rats made diabetic by a single intravenous injection of streptozotocin (55 mg/kg) using a combination of immunocytochemical staining and in situ hybridization histochemistry. In the absence of(More)
Twenty four patients were studied prior to and after 6 and 12 weeks therapy with isotretinoin (17 patients) for acne and related disorders, or with etretinate (7 patients) for psoriasis and related disorders. Patients treated with isotretinoin had a significant reduction in natural killer cell activity at an effector: target cell ratio of 100: 1 at 12 weeks(More)
Cerebral arteriosclerosis was observed upon necropsy of a 36-yr-old female captive polar bear (Ursus maritimus) that developed a sudden onset of seizure-like activity and died. The medium and large cerebral arteries of the meninges had moderate to severe diffuse discoloration and mineralization of the matrix of the tunica media, with little or no associated(More)
There are no approved therapies for muscle wasting in children infected with human immunodeficiency virus (HIV), which portends poor disease outcomes. To determine whether a soluble ActRIIb receptor Fc fusion protein (ActRIIB.Fc), a ligand trap for TGF-β/activin family members including myostatin, can prevent or restore loss of lean body mass and body(More)
