Dye-Sensitized Photocatalyst: A Breakthrough in Green Energy and Environmental Detoxification- Sensitization of semiconductor material is well recognized in the field of photography and photo-electrochemistry. Recently, dye sensitization technique has found its application in solar cells. Dye sensitization ...
Nous rapportons l’observation d’une myocardite lupique sans trouble conductif chez le fœtus d’une femme lupique ayant des anticorps anti-SSA/Ro et anti-SSB/La. L’échographie cardiaque fœtale montrait des signes de myocardiopathie avec des hyperéchogénicités ventriculaires et valv...
Neonatal lupus (NL) is a rare syndrome caused by placental transfer of maternal anti-SSA/Ro (60 and 52kDa) or anti-SSB/La antibodies. The aim of this study was to evaluate the clinical and biological profile of NL at the neonatal unit of Sfax, Tunisia, over a 10-year period. Six ...
All maternal sera contained antibodies to SSA alone or the both SSA and SSB. Three of four subsequent pregnancies were complicated by heart block. One child affected died in utero. While the two other newborns with CHB required pacemaker insertion during the first 3months of life. Although the...
However, the frequency of sicca syndrome (76 %) was unexpected, and must be related to 2 laboratory results :thequasi-absenceof anti-SSA and anti-SSB antibodies in our patients and the presence of two monoclonal immunoglobulins (lgM kappa and lgG lambda). There may be some degree of ...
These include insoluble nuclear antigens (Ags) such as anti-DNA and soluble nuclear Ags (SSA/Ro, SSB/La, Sm, RNP). However, some of them are poorly associated with the evolution of the disease. Recent characterization of Abs in GN, resulted in the development of more reliable tests.T. ...
Isotype-specific enzyme-linked immunosorbent assays have been developed to assess anti-Ro/SSA and anti-La/SSB IgG subclasses in 31 patients with primary Sj?gren's syndrome. The anti-Ro/SSA antibody production was largely restricted to IgG1, whilst the anti-La/SSB subclass distribution varied ...
Antinuclear antibodies (ANA) were detected by an immunofluorescence method, anti-dsDNA and anti-cardiolipin (aCL) antibodies by ELISA, antinucleosome and anti-extractible nuclear antigens (or anti-ENA : anti-Sm, anti-RNP, anti-SSA and anti-SSB) by immunodot. The mean age of the patients ...
The Innolia 庐 ANA Update was better in concordance : anti-SSA/SSB antibodies 95%, anti-SmRNP antibodies 60%, anti-centromere B antibodies 91%. This test, allowing the identification of thirteen differents autoantibodies was in good agreement with Elisa : 153 dot negative serum were Elisa ...
Neonatal lupus is due to passive fetal transfer of maternal anti-SSA/Ro and anti-SSB/La antibodies. The clinical spectrum includes transient skin lesions, hematologic and hepatic disorders, and neurological manifestations. Congenital heart block (CHB) is the main complication, occurring in the ...
