Immobilization of American Beaver () with Nalbuphine, Medetomidine, and Azaperone.

Thirty-two American beavers () were immobilized with a mixture of nalbuphine, medetomidine, and azaperone (NalMedA) for tail transmitter placement and health assessments prior to translocation. Inductions and reversals were very smooth, but regardless of the dose administered, which ranged from 0.02 to 0.

Expression of Ro/SS-A and La/SS-B determined by immunohistochemistry in healthy, inflamed and autoimmune diseased human tissues: a generalized phenomenon.

Objective: Autoantibodies to the ribonucleoproteins Ro/SS-A and La/SS-B are found in autoimmune diseases such as primary Sjögren's syndrome (pSS), systemic lupus erythematousus and rheumatoid arthritis. Increased and aberrant expression of Ro/SS-A and La/SS-B in target organs, which have been reported in the recent literature, might contribute to their antigenicity. However, data on the expression of Ro/SS-A and La/SS-B in other inflammatory conditions are scarce.

Role of islet amyloid in type 2 diabetes mellitus: consequence or cause?

Type 2 diabetes mellitus (DM2) is characterized metabolically by defects in both insulin secretion and insulin action, resulting in hyperglycemia. Histopathologically, DM2 is characterized by depositions of protein in the pancreatic islets. This 'islet amyloid' is present in >90% of patients with DM2, as well as in monkeys and cats with DM2.

Malignant breast tumor phospholipid profiles using (31)P magnetic resonance.

Biochemical markers improve the classification and staging of breast cancer and may refine management decisions if it can be shown that they correlate with accepted prognostic factors or patient outcome. Using phosphorus-31 magnetic resonance spectroscopy ((31)P MRS), we determined the phospholipid content of 43 malignant breast tumors, correlating the profiles with specific histopathologic and clinical features and hormone receptor status. Among the 14 phospholipids identified, the mean mole percentage of sphingomyelin, phosphatidylcholine, phosphatidylserine, phosphatidic acid, phosphatidylglycerol, and alkylacylphosphatidylcholine predicted cellular infiltration, infiltration type, elastosis, lymphatic invasion, perineural invasion, necrosis, and estrogen receptor positivity.

[Lump in the neck: 4 patients with a medullary thyroid carcinoma].

In a 25-year-old man, medullary thyroid carcinoma (probably a solitary sporadic form) was diagnosed following investigation of a small lump in the patient's neck. This was removed and followed up with further treatment. In a 27-year-old man, episodes of headache, palpitations and excessive perspiration (due to a pheochromocytoma) and a positive family history of thyroid problems led to further investigations and the subsequent diagnosis of multiple endocrine neoplasia (MEN) type 2A.
