BACKGROUND The potential health effects of polybrominated diphenyl ethers (PBDEs) that are widely used as flame-retardants in consumer products have been attributed, in part, to their endocrine disrupting properties. The purpose of this study is to examine the in vivo effects of an early exposure to PBDEs on the development of insulin resistance in mice. RESULTS The metabolic consequences of ...

BACKGROUND Proteinuria is the most sensitive predictor of development of progressive renal insufficiency, with increasing focus on the composition of proteinuria, particularly high molecular weight proteins such as immunoglobulin G (IgG) (molecular weight 150 kDa). Differing methods of assessing excretion of proteinuria molecules have limited interpretation of results. We aimed to assess the ut...

A glomerular permeability defect occurs early in the course of type 1 diabetes and precedes the onset of microalbuminuria and renal morphological changes. Recently, ACE inhibitors have been shown to prevent loss of glomerular membrane permselective function, but the mechanism of this nephroprotective effect is still being debated. The objective of the present study was to evaluate the effects o...

BACKGROUND Presentation with a firm type of chronic hepatomegaly of multifactorial etiology is common among school-age children in sub-Saharan Africa. OBJECTIVE Aflatoxin is a liver toxin and carcinogen contaminating staple maize food. In this study we examined its role in chronic hepatomegaly. METHODS Plasma samples collected in 2002 and again in 2004 from 218 children attending two school...

Recent studies have indicated that inflammation-based prognostic scores, such as the Glasgow Prognostic Score (GPS), modified GPS (mGPS) and C-reactive protein/Albumin (CRP/Alb) ratio, platelet-lymphocyte ratio (PLR), and neutrophil-lymphocyte ratio (NLR), have been reported to have prognostic value in patients with many types of cancer, including nasopharyngeal carcinoma (NPC). In this study, ...

In this paper, the metaheuristic method consisting of the adaptive tabu search (ATS) and the practicing heuristic (PH) technique is proposed to provide optimal solutions of the assembly line balancing (ALB) problems. With the multi-objective approach, the ATS is used to address the number of tasks assigned for each workstation, while the PH is conducted to assign the sequence of tasks for each ...

Estrogens modulate the expression of many liver-specific genes in oviparous species. For instance, expression of the estrogen receptor and vitellogenin genes is strongly up-regulated by estradiol in rainbow trout liver. Using hepatocyte primary cultures, we demonstrate that trout albumin (Alb) gene is also regulated by this hormone. Indeed, treatment of hepatocytes with 1 microM estradiol led, ...

BACKGROUND Gelsolin is an actin-binding protein found in the cytoplasm and in extracellular fluids including blood plasma. Plasma gelsolin concentration decreases after a wide range of injuries. We hypothesized that the repletion of gelsolin would limit inflammation and tissue injury in a rat model of sepsis using cecal ligation and double puncture (2CLP). METHODS Human plasma gelsolin (pGSN,...

We have measured plasma volume expansion (Evans blue and hematocrit changes) and hemodynamic responses in conscious hemorrhaged and normovolemic splenectomized sheep after a 30-min infusion of either 20 ml/kg of diaspirin cross-linked hemoglobin (DCLHb), 20 ml/kg of human albumin (Alb), or 60 ml/kg of a solution of Ringer lactate (RL). All regimens expanded blood volume and increased blood pres...

To analyze at the cellular level the decrease in alpha-fetoprotein (AFP) gene expression during the early postnatal growth, we searched for AFP gene transcripts by in situ hybridization using a specific cDNA probe, and for the corresponding protein by immunocytochemistry, on rat liver sections at various times of the perinatal period. The relative number of mRNA sequences was evaluated by North...
