The human high m.w.-melanoma-associated Ag (HMW-MAA) is an attractive target for the immunotherapy of melanoma, due to its relatively high expression in a high percentage of melanoma lesions and its restricted distribution in normal tissues. Active immunization with HMW-MAA mimics has been previously shown to induce a HMW-MAA-specific, T cell-dependent Ab response associated with an apparent cl...
This study was initiated to induce experimental autoimmune anterior uveitis (EAAU) in Lewis rats by melanin-associated antigen (MAA; 22-kDa fragment of type I collagen alpha2 chain) derived from rat iris and ciliary body (CB), to localize MAA within the eye, and to investigate the possible mechanism of MAA generation in vivo. The EAAU model replicates idiopathic human anterior uveitis. Lewis ra...
The mouse anti-idiotype (anti-id) monoclonal antibody (mAb) IMel-1 recognizes an idiotope in the antigen combining site of the immunizing anti-human high molecular weight melanoma-associated antigen (HMW-MAA) mAb 225.28. The mAb IMel-1 is able to induce an immune response against self cross-reacting HMW-MAA in rabbits that express HMW-MAA in normal tissues. Most of the rabbit anti-anti-id antib...
BACKGROUND Optimal androgen signaling is critical for testicular development and spermatogenesis. Methoxyacetic acid (MAA), the primary active metabolite of the industrial chemical ethylene glycol monomethyl ether, disrupts spermatogenesis and causes testicular atrophy. Transcriptional trans-activation studies have indicated that MAA can enhance androgen receptor activity, however, whether MAA ...
The photoluminescence of mercaptoacetic acid (MAA)-capped CdSe/ZnSe/ZnS semiconductor nanocrystal quantum dots (QDs) in SKOV-3 human ovarian cancer cells is pH-dependent, suggesting applications in which QDs serve as intracellular pH sensors. In both fixed and living cells the fluorescence intensity of intracellular MAA-capped QDs (MAA QDs) increases monotonically with increasing pH. The electr...
OBJECTIVE Malondialdehyde-acetaldehyde (MAA) adducts are a product of oxidative stress associated with tolerance loss in several disease states. This study was undertaken to investigate the presence of MAA adducts and circulating anti-MAA antibodies in patients with rheumatoid arthritis (RA). METHODS Synovial tissue from patients with RA and patients with osteoarthritis (OA) were examined for...
The immunogenicity in patients with melanoma, in monkeys, and in rabbits of four human melanoma-associated antigens (MAA) defined by murine monoclonal antibodies was investigated. The latter included the high molecular weight MAA and the (Mr 115,000, 100,000, and 95,000-150,000 MAA. To this end sera from patients with melanoma, from monkeys, and from rabbits immunized with cultured human melano...
Malondialdehyde acetaldehyde (MAA) adducts are generated under oxidative stress and shown to be highly immunogenic. Our aim was to investigate the recognition of MAA adducts by human natural antibodies in newborns before or at the time of full-term pregnancy. Plasma samples of pre-term (n = 11) and full-term (n = 36) newborns were enriched in specific IgM binding to MAA adducts compared with th...
OBJECTIVE In contrast to severe aplastic anemia (SAA), the appropriate management of patients with moderate aplastic anemia (MAA) is unclear. Recently, it was reported that when childhood MAA was treated with supportive care alone, 2/3 of patients progressed to SAA, and therefore patients with MAA should be treated with immunosuppressive (IS) therapy in time. The present study aimed to review t...
Background: Transarterial radioembolization (TARE) relies on directly injected 90Y- or 166Ho-loaded microspheres in the hepatic arteries. The activity to be is generally based pre-TARE 99mTc-macro-aggregated-albumin (MAA) imaging, while actual dose distribution post-treatment images. volume of interest (VOIs) propagation methods (i.e., rigid and deformable) from pre- post-TARE imaging might aff...
