Soil density fractionation is a common tool to separate organic matter of different function and turnover. But it has not been tested so far how much soil material necessary obtain reproducible results. A reduction chemicals like polytungstate would further save valuable resources. Here, we show that weight from 25 5 g was significantly affecting Compared the commonly used 10–25 g, this corresp...

common variable immunodeficiency (cvid) is a heterogeneous group of disorders characterized by hypogammaglobulinemia and an increased susceptibility to recurrent infections as well as autoimmunity and malignancies. idiopathic thrombocytopenic purpura (itp) and autoimmune hemolytic anemia (aiha) are two autoimmune disorders which may be seen in association with cvid. among 85 cvid patients, seve...

The patient was a 47-year-old man diagnosed as having autoimmune hemolytic anemia (AIHA) in April 2011. He also had a congenital chromosomal abnormality, a balanced translocation. Treatment with prednisolone (PSL) 60 mg/day resulted in resolution of the AIHA, and the treatment was completed in November 2011. While the patient no longer had anemia, the direct and indirect Coombs tests remained p...

Autoimmune hemolytic anemia (AIHA) due to warm-acting IgA autoantibodies is rare. We explored the pathogenic mechanisms underlying destruction of red blood cells (RBCs) in a patient with severe AIHA mediated exclusively by polymeric immunoglobulin A (pIgA) anti-Band 3 autoantibodies. The follow-up period was 17 months. RBCs were not destroyed by complement activation as no deposition of complem...

A simple EIA technique for the quantitation of red-cell-bound immunoglobulin (IgG) was devised and applied to normal and pathologic states, including autoimmune hemolytic anemia (AIHA) and other disorders. The mean red-cell-bound IgG value for normal subjects was 73.2 ± 25.8 ng/l0'o red cells (mean ± ISD). Fifteen patients with AIHA had an increased level of red-eell-bound IgG ranging from 109 ...

Chronic lymphocytic leukemia (CLL) is frequently associated with autoimmune diseases directed against constituents of the blood, including hemolytic anemia (AIHA). We hypothesized that CLL cells predispose to hematologic autoimmunity by acting as aberrant antigen-presenting cells (APCs). Initially, it was confirmed that all studied patients with AIHA secondary to CLL harbored activated helper T...

one of the most important adverse environmental effects of herbicide application in production systems is possible damage to non-target plants, such as crops that are grown in rotation. nicosufuron+rimsulfuron (ultima) is a sulfonylurea herbicide that recently registered for use in maize fields in iran. its residues may be present more than a season in certain conditions. to measure nicosufuron...
