A time-resolved immunofluorometric assay (TR-IFMA) was developed for the determination of haptoglobin (Hp) in canine serum. Haptoglobin was purified from canine acute phase serum by ammonium sulphate precipitation followed by gel filtration. This isolated dog Hp was used as the standard to calibrate the assay. Intra- and inter-assay coefficients of variation of the assay were, respectively, 5.7...

The objective of this investigation was to study the effects of feeding backgrounding and finishing diets on selected acute phase proteins in the plasma of feedlot steers. Two groups of 12 steers each, at the backgrounding and finishing stages, were offered either a backgrounding (45% barley grain-based concentrate and 55% barley silage on a DM basis) or a finishing (91% barley grain-based conc...

Introduction In humans, acute phase proteins (APP) are regarded as a useful diagnostic tool in patients with lymphoma, leukaemias and multiple myeloma, and can be used as a prognostic factor and as an early indicator of sepsis. The aim of this pilot study was to examine the acute phase proteins (APP) C-reactive protein (CRP) and haptoglobin in dogs with different malignant, lymphatic blood diso...

Preeclampsia is a pregnancy-specific condition that increases maternal and infant mortality and morbidity. It is diagnosed based on a triad of hypertension, significant proteinuria and rapidly increasing edema during gestation. The factors that initiate preeclampsia are unknown and still a subject of intense clinical research. The objective of this study is to provide additional immunological i...

Transfusion of red blood cells (RBCs) is an effective therapy in surgery and critical care. Comparing to fresh RBCs, the therapeutic effect of stored RBCs is greatly limited because of its loss of NO during storage, which leads to vasodilatation dysfunction upon transfusion. So far, there is no effective solution to this problem. Here, we summarize the protective effects of Haptoglobin (Hp) in ...

Treatment of rabbits with D-penicillamine at doses up to 30 mg/kg, beginning either before or after the onset of antigen-induced experimental arthritis, diminished the severity of the inflammatory synovitis in a considerable proportion of animals as judged by both external joint measurements and terminal histopathological assessment. D-penicillamine treatment had no effect on serum haptoglobin ...

Inflammation has been linked to cancer but its role in breast cancer is unclear. We investigated common serum markers of inflammation: C-reactive protein (CRP), albumin, haptoglobin and white blood cells (WBC) in relation to breast cancer incidence, severity and survival. A total of 155179 women aged 20 and older without any history of cancer were selected from a large Swedish cohort. Hazard ra...

One route to gain insight into the causes and consequences of ecological differentiation is to understand the underlying physiological mechanisms. We explored the relationships between immunological and oxidative status and investigated how birds cope physiologically with the effects of immune-derived oxidative damage. We successively implemented two experimental manipulations to alter physiolo...

We have compared the erythrocyte sedimentation rate (ESR) with other acute phase proteins (C-reactive protein (CRP), alpha(1) antitrypsin, orosomucoid, and haptoglobin) in 108 patients with polymyalgia rheumatica and/or giant cell arteritis. There was good correlation between CRP and ESR, but the ESR was also found to have the highest correlation with disease activity. The additional measuremen...

Transthyretin amyloidosis is a conformational pathology characterized by the extracellular formation of amyloid deposits and the progressive impairment of the peripheral nervous system. Point mutations in this tetrameric plasma protein decrease its stability and are linked to disease onset and progression. Since non-mutated transthyretin also forms amyloid in systemic senile amyloidosis and som...
