BACKGROUND Clusterin is a glycoprotein which participates in a number of pathophysiological processes in the organism. Information about clusterin use in the diagnosis of nephropathy and the differential diagnosis of proteinuria has been published recently. AIM Search for correlations between urinary clusterin concentration and other renal function markers. Evaluation of urinary clusterin mea...

According to the predominant theories, soluble amyloid-beta (Aβ) aggregates are the principal neurotoxic agents in Alzheimer's disease pathology, making them a popular target for the development of therapeutics and diagnostic markers. One of the most commonly used methods for determining the concentration of Aβ is ELISA. However, ELISA was developed for monomeric proteins and may be ill-suited ...

background: the witches’ broom disease of lime caused by candidatus phytoplasma aurantifolia, is the most devastating disease of acidian lime in the southern parts of iran. objectives: at present, no effient method has been developed for controlling the disease, therefore quarantine approaches such as early detection and subsequent eradication of infected trees is very important. toward this ...

The influence of milk yield and milk composition on the diagnosis of Mycobacterium avium ssp. paratuberculosis (MAP) by milk ELISA in the context of the total IgG secretion patterns in milk throughout lactation and serum concentrations were investigated. A 2-yr trial was performed in which 1,410 dairy cows were sampled monthly and MAP milk ELISA status and milk yield and composition were determ...

results the results showed that sensitivity and specificity were respectively 84.12% and 92% for‎ recombinant protein srs3 and 92% and 96% for rsag1. conclusions recombinant proteins srs3 and rsag1 are promising antigens in diagnostic assays for detection of specific antibodies against t. gondii. background infections by the protozoan parasite toxoplasma gondii (t. gondii) are widely prevalent ...

background: although a simple and direct method does not exist for the detection of chlamydial infections, there are situations in which reliable serological tests, with sensi-tivity related to a specific antigen, could be helpful. objective: the aim of this study was to clone the first 1100 bp of the c. trachomatis outer membrane protein 2 (omp2) gene in order to prepare a recombinant protein ...

citrus tristeza virus (ctv) is among the most destructive pathogens of citrus and causes substantial economic losses in citrus-growing industry worldwide. considering recent distribution of this pathogen and its capability of transmission by existing aphid vectors in iran, detection of this virus is enforceable for controlling the damage caused by this pathogen in iran, as one of the major citr...

BACKGROUND Although hereditary protein S (PS) deficiency is clearly associated with venous thromboembolism (VTE), the importance of low PS concentrations as a risk factor for VTE in other patients is still a matter of debate. To clarify this issue, we designed a case-control study to evaluate the role of different molecular forms of plasma PS. METHODS We quantified plasma cleaved, total, and ...

individual preparation of two human t-cell lymphotropic virus type i (htlv-i) diagnostic gst fused peptides (mta-1 and gd21) is time-consuming and expensive. the aim of this study was to design a novel single chimeric antigen (sca) to obviate separate expression of proteins and reduce the cost of reagent preparation.structural protein fragments, including immunodominant b cell linear epitopes, ...
