A student had haemoglobin in the urine after running but not after cycling. The haemoglobinuria was related to the hardness of the surface on which he ran and to his running style. The concentration of haptoglobin in his plasma was less than normal. This was most pronounced after he had been running, when haptoglobin had combined with free haemoglobin, but the concentration was also low when th...

Coronary collateral development relies on the coordinated secretion of growth factors. However, alone they are insufficient for permanent collateral growth. We utilized proteomics to identify other important proteins in the extracellular environment that could facilitate collateralization. Chronically instrumented dogs developed coronary collaterals by the repetitive occlusion method. Subendoca...

HP and HPR are related and contiguous genes in strong linkage disequilibrium (LD), encoding haptoglobin and haptoglobin-related protein. These bind and chaperone free Hb for recycling, protecting against oxidation. A copy number variation (CNV) within HP (Hp1/Hp2) results in different possible haptoglobin complexes which have differing properties. HPR rs2000999 (G/A), identified in meta-GWAS, i...

Human haptoglobin, the serum haemoglobinbinding protein, can be differentiated into three common phenotypes (Hp i-i, Hp 2-I, and Hp2-2) by means of starch gel electrophoresis at pH 8-6 (Smithies, 1955). These differences were thought to be determined by a pair of allelic genes Hp" and Hp2 (Smithies and Walker, I955, I956). However, chemical reduction of purified haptoglobin followed by electrop...

The effects of the dietary inclusion of two levels of short-chain fructooligosaccharides (sc-FOS) on weight loss, biochemical parameters and serum haptoglobin concentration were investigated in twelve experimental obese Beagle dogs. Dogs were randomised into two groups and submitted to a weight loss program (WLP): the control group (C) received a commercial energy-restricted high-protein diet c...

Sera from 25 metastatic breast cancer patients and 25 healthy controls were subjected to affinity chromatography using immobilized galectin-1. Serum from the healthy subjects contained on average 1.2 mg per ml (range 0.7-2.2) galectin-1 binding glycoproteins, whereas serum from the breast cancer patients contained on average 2.2 mg/ml (range 0.8-3.9), with a higher average for large primary tum...

143) were transported 2,200 km to central Oklahoma. As an estimate of inflammation, concentrations of ceruloplasmin, fibrinogen, and haptoglobin were measured in blood samples collected at weaning, 24 and 72 h post-weaning, and on the day of shipping, 24 and 72 h after arrival. Fixed effects were breed type (n = 9 levels: straightbreds [RR, AA, BB], and crossbreds [RA, AR, RB, BR, AB, BA] where...

Ultracentrifugal studies of the alpha(2)-proteins of normal human serum before and after the addition of hemoglobin have revealed three separate and clearly distinguishable patterns based on the three major serum haptoglobin groups. Isolation of the three haptoglobin hemoglobin complexes disclosed characteristic patterns for each group. The heterozygote was found to possess electrophoretic and ...

objective(s)the aim of this study was to evaluate plasma levels of nitric oxide (no) and certain acute phase proteins(caeruloplasmin, transferrin, haptoglobin, c-reactive protein) in nigerian subjects after short and prolonged exercises.materials and methodsa total of 57 subjects (34 males and 23 females) between ages of 19 and 45 years participated in this study and weredivided into three grou...
