A hallmark of systemic lupus erythematosus and the MRL murine model for lupus is the presence of anti-double-stranded (ds)DNA antibodies (Abs). To identify the steps leading to the production of these Abs in autoimmune mice, we have compared the phenotype and localization of anti-dsDNA B cells in autoimmune (MRL+/+ and lpr/lpr) mice with that in nonautoimmune (BALB/c) mice. Anti-dsDNA B cells a...
Accumulating evidence suggests that autoreactive plasma cells play an important role in systemic lupus erythematosus (SLE). In addition, several proinflammatory cytokines promote autoreactive B cell maturation and autoantibody production. Hence, therapeutic targeting of such cytokine pathways using a selective JAK2 inhibitor, CEP-33779 (JAK2 enzyme IC(50) = 1.3 nM; JAK3 enzyme IC(50)/JAK2 enzym...
Transplantation of bone marrow cells of lpr/lpr mice into irradiated normal mice fails to develop massive lymphadenopathy or autoimmunity but causes severe graft-vs.-host-like syndrome. To elucidate an abnormality of lpr/lpr bone marrow-derived T cells, we transplanted bone marrow cells of Mlsb lpr/lpr mice into H-2-compatible Mlsa non-lpr mice. Although lpr/lpr T cell precursors repopulated th...
In the neonatal mouse ovary, clusters of oocytes called nests break into smaller cysts and subsequently form individual follicles. During this period, we found numerous mast cells in the ovary of MRL/MpJ mice and investigated their appearance and morphology with follicular development. The ovarian mast cells, which were already present at postnatal day 0, tended to localize adjacent to the surf...
Abstract Chlorpyrifos is an organophosphate insecticide. It has low aqueous solubility, volatile and non-mobile, moderately persistent in soil, highly toxic to mammals, acetylcholinesterase inhibitor. The main use of chlorpyrifos control various types agricultural pests. This study aims determine the absorption residues maize plants. was conducted July-December 2019. Experimental research at Ja...
We propose a practical approach for performing high-resolution MR lymphangiography (MRL). We shall discuss and illustrate the technical approach for the visualization of lymphatic vessels in patients suffering from lymphedema, how to distinguish lymphatic vessels from veins, and MRL role in supermicrosurgery treatment planning. A brief review of literature, from a technical point of view, is al...
In this paper, we propose and compare two spectrum decision schemes namely; Adaptive Spectrum Decision (ASD) and Maximum Remaining Lifetime (MRL). The simulation results and performance analysis such as channel utilization, data delivery, and spectrum handoff rate are evaluated and compared. The results obtained that ASD has great performance in comparison with MRL scheme. KeywordsSpectrum deci...
MRL-I/r/I/r mice spontaneously develop various manifestations of autoimmunity indnding an inflammatory arthropathy and immune complex glomerulonephritis. This study examines the role of nitric oxide, a molecule with proinfhmmatory actions, in the pathogenesis of MRL1/r/I/r autoimmune disease. MRL-I/r/I/r mice excreted more urinary nitrite/nitrate (an in vivo marker of nitric oxide production) t...
Borna disease virus (BDV) frequently causes meningoencephalitis and fatal neurological disease in young but not old mice of strain MRL. Disease does not result from the virus-induced destruction of infected neurons. Rather, it is mediated by H-2(k)-restricted antiviral CD8 T cells that recognize a peptide derived from the BDV nucleoprotein N. Persistent BDV infection in mice is not spontaneousl...
OBJECTIVE To investigate the feasibility of gadolinium (Gd) contrast-enhanced magnetic resonance lymphangiography (MRL) in breast cancer patients within a typical clinical setting, and to establish a Gd-MRL protocol and identify potential MRL biomarkers for differentiating metastatic from non-metastatic lymph nodes. MATERIALS AND METHODS 32 patients with unilateral breast cancer were enrolled...
