BACKGROUND: Allergic contact dermatitis (ACD) is associated with increased production of cytokines. The patch test is the "gold-standard" diagnostic method, but it poses a risk of false results. OBJECTIVE: To evaluate a novel laboratory technique, the Luminex LiquiChip, which simultaneously measures blood levels of multiple cytokines, as a diagnostic tool in patients with chrome-induced ACD. METHODS: The study group included 20 patients with ACD and relevant patch test results for potassium dichromate and 19 patients with ACD for nickel or fragrance as control...

A human bone marrow-derived mesenchymal stromal cell (MSCs) and cord blood-derived CD34+ stem cell co-culture system was set up in order to evaluate the proliferative and differentiative effects induced by MSCs on CD34+ stem cells, and the reciprocal influences on gene expression profiles. After 10 days of co-culture, non-adherent (SN-fraction) and adherent (AD-fraction) CD34+ stem cells were collected and analysed separately. In the presence of MSCs, a significant increase in CD34+ cell number was observed (fold increase = 14...

The safety and high quality of ethnic ready-to-eat foods as a source of nourishment and food supplies chain to the remote areas become particularly important. Consuming healthy and balanced nutritional foods means eating better quality foods in proper quantities. Such foods can be developed through a preservation technique by using ionizing radiation. Although implementation of the technology for certain foodstuffs has been implemented in some countries, application of the process to a complete set of meals for selected target groups is still very limited...

An acceptable area for collecting DNA reference sample is a part of the forensic DNA analysis development. The aim of this study was to evaluate skin surface cells (SSC) as an alternate source of reference DNA sample. From each volunteer (n = 10), six samples from skin surface areas (forearm and fingertips) and two traditional samples (blood and buccal cells) were collected. Genomic DNA was extracted and quantified then genotyped using standard techniques. The highest DNA concentration of SSC samples was collected using the tape/forearm method of collection (2...

Transforming growth factor-beta (TGF-β) signaling has gained extensive interest in hepatocellular carcinoma (HCC). The small molecule kinase inhibitor galunisertib, targeting the TGF-β receptor I (TGF-βRI), blocks HCC progression in preclinical models and shows promising effects in ongoing clinical trials. As the drug is not similarly effective in all patients, this study was aimed at identifying new companion diagnostics biomarkers for patient stratification. Next-generation sequencing-based massive analysis of cDNA ends was used to investigate the transcriptome of an invasive HCC cell line responses to TGF-β1 and galunisertib...

BACKGROUND: Polyomavirus-associated nephropathy (PVAN) following BK virus reactivation in kidney transplant recipients (KTR) can compromise graft survival. Lowering immunosuppression is the only established approach to prevent or treat PVAN but nonspecifically increasing host immune competence also augments rejection risk. Ex vivo T cell stimulation/expansion offers the possibility to generate BK-specific T cell lines for adoptive immunotherapy. The objective of this study was to develop and characterize a clinical scale protocol to generate BK-specific T cell lines from viremic KTR...

Mice with the hypomorphic AIF-Harlequin mutation exhibit a highly heterogeneous mitochondriopathy that mostly affects respiratory chain complex I, causing a cerebral pathology that resembles that found in patients with AIF loss-of-function mutations. Here we describe that the antidiabetic drug pioglitazone (PIO) can improve the phenotype of a mouse Harlequin (Hq) subgroup, presumably due to an inhibition of glycolysis that causes an increase in blood glucose levels. This glycolysis-inhibitory PIO effect was observed in cultured astrocytes from Hq mice, as well as in human skin fibroblasts from patients with AIF mutation...

PURPOSE: Chlorella vulgaris (CV) has exhibited immune-enhancing and protective activities against cancer and infections. However, there is an increasing concern about the use of Chlorella species in human, regarding its various molecules with antigenic features found in infectious microorganisms. Our goal was to investigate the impact of higher concentrations of CV on tumor growth in spontaneous mouse mammary tumor (SMMT) models. METHODS: Balb/c mice were daily given CV powder at doses of 0, 200, or 300 mg/kg for 42 days (CONTROL, CV200, and CV300 groups, respectively; n = 6/group)...

BACKGROUND: Interleukin (IL)-17 produced by mainly T helper 17 (Th17) cells may play an important destructive role in chronic periodontitis (CP). Thus, anti-inflammatory cytokines, such as IL-35, might have a beneficial effect in periodontitis by inhibiting differentiation of Th17 cells. Th17 differentiation is regulated by the retinoic acid receptor-related orphan receptor (ROR) α (encoded by RORA) and RORγt (encoded by RORC). However, the role of IL-35 in periodontitis is not clear and the effect of IL-35 on the function of Th17 cells is still incompletely understood...

Damage to endothelial cells contributes to acute kidney injury (AKI) by leading to impaired perfusion. Endothelial colony-forming cells (ECFCs) are endothelial precursor cells with high proliferative capacity, pro-angiogenic activity, and in vivo vessel forming potential. We hypothesized that ECFCs may ameliorate the degree of AKI and/or promote repair of the renal vasculature following ischemia/reperfusion (I/R). Rat pulmonary microvascular ECs (PMVEC) with high proliferative potential were compared with pulmonary artery ECs (PAEC) with low proliferative potential in rats subjected to renal I/R...

BACKGROUND: Familial eosinophilia (FE) is a rare autosomal dominant inherited disorder characterized by the presence of lifelong peripheral eosinophilia (>1500/μL). Mapped to chromosome 5q31-q33, the genetic cause of FE is unknown, and prior studies have failed to demonstrate a primary abnormality in the eosinophil lineage. OBJECTIVE: The aim of the present study was to identify the cells driving the eosinophilia in FE. METHODS: Microarray analysis and real-time PCR were used to examine transcriptional differences in peripheral blood mononuclear cells (PBMC), and in purified cell subsets from affected and unaffected family members belonging to a single large kindred...

We describe here a strategy that can distinguish between Staphylococcus species truly present in a clinical sample from contaminating Staphylococcus species introduced during the testing process. Contaminating Staphylococcus species are present at low levels in PCR reagents and colonize lab personnel. To eliminate detection of contaminants, we describe an approach that utilizes addition of sufficient quantities of either non-target Staphylococcal cells (Staphylococcus succinus or Staphylococcus muscae) or synthetic oligonucleotide templates to helicase dependent isothermal amplification reactions to consume Staphylococcus-specific tuf and mecA gene primers such that contaminating Staphylococcus amplification is suppressed to below assay limits of detection...

Monocytes play a vital role in HIV-associated neurocognitive disorder (HAND), postulated to transport HIV into the brain and secrete pro-inflammatory cytokines. We analyzed cytokines released by cultured peripheral blood mononuclear cells enriched with the CD14 marker isolated from HIV-infected individuals with HAND and normal cognition (NC) in combination antiretroviral therapy naive and after 1 year on treatment. Interleukin-8 and monocyte chemoattractant protein-1 levels were higher in HAND compared with NC at baseline (P = 0...
