Preventing intense false positive and negative reactions attributed to the principle of ELISA to re-investigate antibody studies in autoimmune diseases [PDF]

open access: yes, 2014
To study the possible involvement of potential environmental pathogens in the pathogenesis of autoimmune diseases, it is essential to investigate antibody responses to a variety of environmental agents and autologous components.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

False positive reactions obtained with any of the four DENV ICB ELISAs and with IIF. [PDF]

open access: yes, 2013
∶>10. ICB ELISA positive: P/N. 136 serum samples without antibody to DENV were compared. In the absence of competitive iTBEP antigen the ICB ELISA produced 5 false positive results.

EFFECTIVENESS OF TUBERCULOUS RECOMBINANT ALLERGEN SKIN TESTS FOR DETECTING TUBERCULOSIS IN CHILDREN AND ADOLESCENTS OF MOSCOW IN 2013

open access: yesПедиатрическая фармакология, 2015
Explanation. Mantoux test is used to detect the tuberculous infection; however, low specificity of this method results in a high rate of false positive responses due to cross-reactions of PPD (protein purified derivate) antigens contained in many ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Serum fractions associated with positive and false positive reactions in the ELA test for trichinellosis in swine. [Accuracy of packinghouse tests for Trichinella in pork] [PDF]

open access: yes, 1976
A considerable number of packinghouse swine sera give false positive results in the enzyme-labeled antibody (ELA) test for Trichinosis. Efforts to understand the nature of this problem directed toward isolation and identification of a serum factor ...
