The aim of this study is to evaluate serum beta 2-microglobulin and neopterin levels in children with febrile illness and to clarify their relation to influenza and febrile seizures (FS). We studied 34 patients with febrile illness whose age was between 1 and 6 years. Influenza A antigen in the throat swab was positive in 17 patients (Flu group) and was negative in 17 (control group). Serum lev...

In 6 patients with primary human immunodeficiency virus type 1 (HIV-1) infection, concentrations of HIV-1 RNA and beta(2)-microglobulin were monitored in cerebrospinal fluid (CSF) and in plasma during antiretroviral therapy. Four patients had neurological symptoms. At baseline, the CSF of 5 patients had detectable levels of HIV-1 RNA (median, 3.68 log(10) copies/mL; range, <2.60-5.67 log(10) co...

By differential screening of a rat liver cDNA library, we have isolated several cDNA clones whose respective mRNAs are decreased in liver from diabetic rats. One such clone corresponding by DNA sequence to alpha 2-microglobulin mRNA has been used in the present study. As it was described previously a reduction (10 times) of alpha 2-microglobulin mRNA levels is observed in liver from diabetic an...

Objective. After filtration through glomeruli, β2-microglobulin is reabsorbed in proximal tubules. Increased urinary β2-microglobulin indicates proximal tubule injury and measurement of β2-microglobulin in urine is useful to determine the source of renal injury. Kidney injury molecule-1 (KIM-1) has been characterized as a selective proximal tubule injury marker. This study was designed to evalu...

BACKGROUND Membranes fabricated from nominally similar polymers may be markedly different in chemical composition, morphology and geometry. To examine the relative importance of these factors to dialyzer performance, the removal of small and large uraemic toxins was determined for dialyzers containing 'polysulfone' membranes of different composition and morphology, with and without fibre undula...

Two cases of beta 2 microglobulin amyloidosis following long term haemodialysis found during necropsy are reported. The patients were 59 and 65 year old Japanese men, respectively. In both cases, systemic distribution of beta 2 microglobulin amyloid deposits was observed. The gastrointestinal tract including the stomach, small intestine, and colon showed the distinctive gross feature of rippled...

a1-Microglobulin is a 26-kd protein, widespread in plasma and tissues and wellconserved among vertebrates. a1-Microglobulin belongs to the lipocalins, a protein superfamily with highly conserved 3-dimensional structures, forming an internal ligand binding pocket. The protein, isolated from urine, has a heterogeneous yellow-brown chromophore bound covalently to amino acid side groups around the ...

Beta2-microglobulin was investigated in atypical haemochromatosis patients not homozygous for the C282Y mutation of HFE (OMIM *235200), because the HFE protein binds beta2-microglobulin, and in mice beta2-microglobulin gene knockout causes hepatic iron overload. Six unrelated patients with atypical haemochromatosis were studied. Five patients had normal HFE coding sequence and the sixth was het...

OBJECTIVE To conduct a systematic review of the efficacy of single-agent bortezomib vs. single-agent thalidomide in patients with relapsed/refractory multiple. METHODS Publications in English from 1966 to June 2005 (MEDLINE, EMBASE, Cochrane library), publication reference lists, Janssen-Cilag data-on-file and abstracts from recent multiple myeloma conferences were reviewed. Prospective studi...
