Migratory large vessel vasculitis preceding acute myeloid leukemia: a case report.

Background: Large vessel vasculitis is a rare disorder usually occurring in the context of the autoimmune conditions of giant cell arteritis and Takayasu's arteritis. Case reports have described large vessel vasculitis occurring in individuals with myelodysplastic syndrome, preceding transformation to acute myeloid leukemia.

Case Presentation: A 56-year-old Afghanistan-born woman presented with fever, a tender left carotid artery, and raised inflammatory markers.

Comparison of two extractable nuclear antigen testing algorithms: ALBIA versus ELISA/line immunoassay.

Extractable nuclear antigen (ENA) antibody testing is often requested in patients with suspected connective tissue diseases. Most laboratories in Australia use a two step process involving a high sensitivity screening assay followed by a high specificity confirmation test. Multiplexing technology with Addressable Laser Bead Immunoassay (e.

The effect of thymulin on avian IL-2 receptor expression.

The effect of thymulin on IL-2 receptor (IL-2R) expression by avian splenocytes was examined in the functionally hypothyroid sex-linked dwarf (SLD) and in normal euthyroid K strain chickens. Daily thymulin injections of 0, 0.05 and 5.

Effects of in vivo thyroid hormone treatment on the expression of interleukin-2 receptors on avian splenocytes.

Cornell K strain chickens received a diet supplemented with 0, 0.1 and 1.0 ppm T3 from the day of hatching.

Effect of triiodothyronine and in vitro growth hormone on avian interleukin-2.

One-day-old chickens were treated with varying levels of triiodothyronine (T3) added to the diet. At 28 days of age, the IL-2-like activity in the splenocyte culture supernatants were assessed. The lowest dose of T3 (0.

Characterization of proteins of chicken infectious anemia virus with monoclonal antibodies.

Eight monoclonal antibodies (MAbs) against chicken infectious anemia virus (CIAV) were developed. These MAbs identified three isolates adapted to grow in the Marek's disease chicken cell line MSB1 (Cux-1, GA-1, and Conn-B) and the chicken-propagated CIA-1 isolate. All MAbs stained MSB1 in the same way with mostly perinuclear staining, although larger nuclear inclusions and cytoplasmic staining were also detected.

Isolation and identification of chicken infectious anemia virus in Brazil.

Seven chicken infectious anemia virus (CIAV) isolates were obtained from seven broiler flocks with poor performance in two states of Brazil. All isolates induced thymus atrophy, bone-marrow aplasia, and low hematocrit values when inoculated into 1-day-old susceptible chicks. The CIAV isolates were resistant to treatment with chloroform and were able to pass through 50-nm-pore-size filters.
