background and objective: serum creatinine is the most used endogenous marker of glomerular filtration rate (gfr), but it also has multiple limitations. therefore, some surrogate gfr markers, such as beta trace protein, have been introduced for gfr estimation. the aim of our study was to estimate gfr by serum beta trace protein using three available equations and compare them to dtpa gfr as the...

The low-molecular weight beta-trace protein constitutes about seven per cent of the total protein content in human cerebrospinal fluid. Within the central nervous system the protein is found predominantly in white matter and fractions enriched in glial cells. Immunofluorescence studies on sections of monkey brains show that beta-trace protein is particularly localized to cells such as astrocyte...
We have isolated beta-trace protein from cerebrospinal fluid, serum, plasma, and urine samples of normal volunteers and sera and hemofiltrate of patients with chronic renal failure. Blood-derived and urinary beta-trace have significantly higher molecular weights than their cerebrospinal fluid counterpart, the amino acid sequences being identical. Oligosaccharide structural analysis revealed the...
OBJECTIVE Beta-trace protein concentrations in cerebrospinal fluid (CSF), serum and nasal secretions are investigated with a new quantitative, immunonephelometric assay. RESULTS The mean beta-trace concentration of normal lumbar CSF (18.4 mg/l) and normal serum (0.59 mg/l), from n = 132 control patients, were 10% higher than reported earlier for smaller control groups. The reference range of ...
OBJECTIVE To evaluate the gene expression of beta-trace protein in urine of diabetic patients, with no reduction in glomerular filtration rate, which was defined as below 60mL/min/1.73m2. METHODS Type 2 diabetes mellitus patients were recruited, and a group of non-diabetic individuals served as control. Beta-trace protein gene expression was analyzed by quantitative PCR. Blood samples were co...
OBJECTIVES In animal models and in vitro studies leptomeninges have been shown to be the origin of neurotrophic substances that support the survival and growth of neuronal cells. Because dementia is associated with neuronal loss, we investigated whether leptomeningeal dysfunction may be involved in the pathogenesis of dementia disorders. METHODS We analysed the cerebrospinal fluid (CSF) conce...
The synthesis and characterization of a new mesoporous Covalent Organic Framework BTP-COF is described, the latter having fully accessible pores with an open diameter of 4.0 nm.
OBJECTIVES To determine the sensitivity and specificity of a nephelometric beta-trace protein assay for the diagnosis of liquorrhoea. METHODS One hundred and forty clinical samples with suspected liquorrhoea were analysed by a newly developed nephelometric assay. An established electroimmunoassay served as a reference method. The sensitivity and specificity of the beta-trace nephelometric ass...
introduction: astrocytes, the most abundant glia in the central nervous system, modulate neuronal survival and function. astrocytic functions are mediated by synthesis and secretion of wide ranges of polypeptides through mechanism (s) poorly understood. among these, tgfβs are synthesized and released by the astrocytes. in this study, the involvement of wnt signaling pathway on the synthesis of ...
