Association between Gastric Cancer Risk and Serum Antibody Titers.

Background/aims: It is difficult to confirm the accurate cutoff value to diagnose infection using commercial serology kits. It is reported that there were many cases with present/past infection that even the serum -IgG antibody (Ab) titers were below the cutoff value (e.g.

Circulating levels of 7 S domain of type IV collagen and atrial natriuretic peptide in normotensive type 2 diabetic patients with or without retinopathy.

Thickening of the basement membrane and other structural alterations of the vascular walls occur frequently in patients with diabetes. The vascular response to atrial natriuretic peptide (ANP) is also altered in these patients. Abnormal vascular response in diabetes may be due to alteration of vascular physicochemical properties induced by accumulation of components of vascular basement membrane.

Serum erythropoietin concentrations and iron status in patients on chronic hemodialysis.

We studied the relationship between serum erythropoietin (EPO) concentration and iron status in 67 patients undergoing chronic hemodialysis. Serum concentrations of EPO were measured by RIA with recombinant human EPO. The geometric mean of the serum EPO concentration was 10.
