A new reagent, 2,2-dicarboxydiphenylamine, vanadox, is proposed for the photometric determination of vanadium in steels, high temperature alloys and ferrotitanium ores. In strongly acidic medium the reagent is selective for vanadium(V) and only eerium(IV) interferes.

Background: Familial Mediterranean Fever is a common genetic autoinflammatory disease prevalent in the Mediterranean region. The clinical course of the disease is characterized by fever and serositis attacks. While defects in the innate immune system are known to play a role in the pathogenesis of the disease, the impact of the adaptive immune system remains unclear.

Background: In Alzheimer's disease (AD), a major gap remains in the understanding of how the interplay between peripheral and central immune systems drives neuroinflammation and disease progression. More recently, the concept of brain lymph drainage has sparked interest as it may shed light on how the dynamics of T cell interactions contribute to AD. Our preliminary study aims to characterize alterations in the peripheral blood lymphocyte population among individuals with AD-dementia and mild cognitive impairment (MCI), as compared with cognitively unimpaired (CU) individuals.

The low levels of GFAP, Nf-L, and Tau in serum and plasma require highly sensitive assays to detect them. Here, we report the analytical validation of an ultrasensitive, electrochemiluminescence-based, multiplexed immunoassay for neurological biomarker assessment.

Amyloid beta 1-42 and 1-40 peptides and the amyloid beta 1-42/1-40 ratio are hallmarks of AD and are commonly monitored in Cerebro-Spinal Fluid (CSF) along other AD biomarkers, to support diagnosis and management of AD patients. Over the past few years, blood-based AD biomarkers have emerged as highly relevant and more practical alternatives to CSF biomarkers, and further technical performance characterization of the associated assays would be beneficial to the AD research and medical community.

Alzheimers Dement
December 2024
Department of Psychiatry, University of Magdeburg,, Magdeburg, Sachsen-Anhalt, Germany.
Background: To support diagnosis of Alzheimer's disease (AD), concentrations of Aβ, tTau and pTau(181) and the Aβ/Aβ ratio are determined in cerebrospinal fluid (CSF). To increase standardization and comparability between diagnostic laboratories, certified reference material (CRM) is used to evaluate the trueness of novel assays. Due to lack of CRMs for tTau, pTau(181), and Aβ, comparability may be assessed by comparing assays from different manufacturers.
