BACKGROUND Haptoglobin (H) is a glycoprotein that regulates the immune response. Serum haptoglobin levels are significantly higher in patients with advanced epithelial ovarian cancer (EOC) with poor survival. Different isoforms of haptoglobin have been found in the serum of patients with EOC. We studied the genetic susceptibility and outcome of patients with EOC correlated to H phenotypes. MA...

Human haptoglobin is classified into three major phenotypes: Hp1-1, Hp2-1 and Hp2-2; there are two autosomal alleles Hp*1 and Hp*2, and the Hp*1 allele has two subtypes, Hp*1F and Hp*1S. Haptoglobin acts as an antioxidant, preventing hemoglobin-driven oxidative damage. We used the comet assay to examine oxidative damage to DNA induced by hydrogen peroxide in human leukocytes; we also looked for...

The participation of free radical oxidation processes is suggested to occur in the mechanism of biological effects of electromagnetic radiation (EMR) that finds more evidence in experimental facts. For inhibition of free radical reactions, including process of lipid peroxidation, there is an antioxidant system in tissues and organs. Haptoglobin as an antioxidant involved in the regulation of ho...

Altered glycosylation in glycoproteins is associated with carcinogenesis, and certain glycan structures and glycoproteins are well-known markers for tumor progression. To identify potential diagnostic candidate markers, we have developed a novel method for analysis of glycosylation changes of glycoproteins from crude serum samples using lectin-based glycoprotein capture followed by detection wi...

Risk stratification of patients with pulmonary embolism (PE) may identify patients at high risk of early death who may benefit from more intensive surveillance or aggressive therapy. Nontargeted proteomics may identify biomarkers useful for the risk stratification of patients with acute symptomatic pulmonary embolism (PE). We studied 6 patients presenting with low-risk PE and 6 patients present...

Immune tolerance to transplanted organs is impaired when the innate immune system is activated in response to the tissue necrosis that occurs during harvesting and implantation procedures. A key molecule in this immune pathway is the intracellular TLR signal adaptor known as myeloid differentiation primary response gene 88 (MyD88). After transplantation, MyD88 induces DC maturation as well as t...

background: allergic rhinitis (ar) is an allergic disorder of the nasal tissue that underlies diseases such as sinusitis, otits and asthma. different predisposing factors including immunological and non-immunological factors contribute to the disease pathogenesis. objective: to investigate association of haptoglobin (hp) phenotypes (hp1-1, 2-1 and 2-2) with serum immunoglobulins a and e levels ...

BACKGROUND: The acute phase response is beneficial to theanimal in restoring homeostasis, and measuring the circulatingacute phase proteins, cytokines, and enzymes can be used toevaluate the innate immune system's responses to invader agentssuch as bacterial lipopolysaccharide. Measurement of theseparameters has shown to be useful as diagnostic and prognosticmarkers in animal endotoxemia. OBJEC...
