BACKGROUND: Cystatin-C (CyC) is a middle molecule that is freely filtered at the glomerulus and almost completely reabsorbed by the proximal tubules. The aim of this study was to evaluate serum CyC and its reduction ratio as a biomarker for assessing the adequacy of the hemodialysis (HD) sessions in children with end-stage renal disease on maintenance HD. We also compared levels of CyC in patients on low-flux HD (LFH) and high-flux HD (HFH). METHODS: Forty patients were included in the study and divided into two groups, with one group (16 patients) receiving HFH and the other group receiving LFH (24 patients) (high-flux and low-flux polysulfone filters, respectively)...

Real-time reverse transcription-polymerase chain reaction (RT-PCR) analysis is a popular method for the measurement of mRNA expression level and is a critical tool for basic research. The identification of suitable reference genes that are stable and not affected by experimental conditions is a critical step in the accurate normalization of RT-PCR. On the other hand, the levels of numerous transcripts exhibit circadian oscillation in various peripheral tissues and it is thought to be regulated by feeding rhythms in addition to the molecular circadian clock...

In normal B-cells, B-cell antigen receptor (BCR) signaling can be negatively regulated by the low-affinity receptor FcγRIIb (CD32b). To better understand the role of FcγRIIb in chronic lymphocytic leukemia (CLL), we correlated its expression on 155 samples from newly-diagnosed Binet A patients with clinical characteristics and outcome. FcγRIIb expression was similar in normal B-cells and leukemic cells, this being heterogenous among patients and within CLL clones. FcγRIIb expression did not correlate with well known prognostic markers [disease stage, serum beta-2 microglobulin (B2M), IGHV mutational status, expression of ZAP-70 and CD38, and cytogenetics] except for a weak concordance with CD49d...

BACKGROUND: Plasma DNA-histone complexes and total free-plasma DNA have the potential to quantify the ischaemia-reperfusion damages occurring after cardiac arrest. Furthermore, DNA-histone complexes may have the potential of being a target for future treatment. The aim was to examine if plasma DNA-histone complexes and the levels of total free-plasma DNA were elevated in post-cardiac arrest patients compared with healthy individuals, and to examine if these biomarkers were capable of predicting mortality...

Human major histocompatibility complex class I (MHC I) - or human leukocyte antigen (HLA) - proteins present intracellularly processed peptides to cytotoxic T lymphocytes in the adaptive immune response to pathogens. A high level of polymorphism in human MHC I proteins defines the peptide-binding specificity of thousands of different MHC alleles. However, polymorphism as well as the peptide ligand can also affect the global dynamics of the complex. In this study, we conducted classical molecular dynamics simulations of two HLA alleles, the ankylosing spondylitis (AS) associated/tapasin-dependent HLA-B*27:05 and nondisease-associated/tapasin-independent HLA-B*27:09, both in peptide-free forms as well as complex with four different peptides ligands...

CD52 is a glycoprotein expressed on normal as well as leukemic immune cells and shed as soluble CD52 (sCD52). We studied sCD52 levels in three CLL cohorts: the 'early', the 'high-risk', and the 'ibrutinib-treated'. The 'high-risk' patients had significantly higher sCD52 levels than the 'early' patients. For the 'early' patients, high sCD52 levels were associated with a significantly shorter time to first treatment. Regarding prognostic factors, no clear correlations with stage, IGHV, or beta-2-microglobulin were found; in a cox multivariate analysis of the 'early' patients, sCD52 and IGHV both had independent prognostic value...

Groupers are an economically important fish species in world fishery markets. Because many studies using RT-qPCR have addressed gene expression in groupers, appropriate reference genes are required to obtain reliable and accurate results. In this study, the most suitable reference genes were identified from eleven candidate genes of one of the most valuable species, Epinephelus akaara, in a range of different experimental conditions. Using the software packages geNorm, NormFinder, BestKeeper and refFinder, three traditionally used reference genes, β-actin (β-ACT), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and beta-2-microglobulin (B2M), were identified as not suitable for E...

The study included 1848 diffuse large B-cell lymphoma (DLBCL)patients treated with chemotherapy/rituximab. The aims were to validate the National Comprehensive Cancer Network International Prognostic Index (NCCN-IPI) and explore the effect of adding high Beta-2 microglobulin (β2M), primary extranodal presentation and intense treatment to the NCCN-IPI variables in order to develop an improved index. Comparing survival curves, NCCN-IPI discriminated better than IPI, separating four risk groups with 5-year overall survival rates of 93%, 83%, 67% and 49%, but failing to identify a true high-risk population...
