A study of the differences between the capacitance of freshly exfoliated highly ordered pyrolytic graphite (HOPG, sample denoted FEG), HOPG aged in air (denoted AAG) and aged in an inert atmosphere (hereafter IAG) is presented in this work. The FEG is found to be more hydrophilic than AAG and IAG since the aqueous electrolyte contact angle (CA) increases from 61.7o to 72.5o and 81.8o after aging in Ar and air, respectively. Electrochemical impedance spectroscopy (EIS) shows the FEG has higher intrinsic capacitance (6...

BACKGROUND: Epithelial ovarian cancer (EOC) is the fifth leading cause of cancer death among women in the United States (5 % of cancer deaths). The standard treatment for patients with advanced EOC is initial debulking surgery followed by carboplatin-paclitaxel combination chemotherapy. Unfortunately, with chemotherapy most patients relapse and die resulting in a five-year overall survival around 45 %. Thus, finding novel therapeutics for treating EOC is essential. Connectivity Mapping (CMAP) has been used widely in cancer drug discovery and generally has relied on cancer cell line gene expression and drug phenotype data...

INTRODUCTION: Mechanical circulatory support may be considered as a therapeutic option in selected patients with refractory cardiac arrest (rCA). Animal studies suggest a potential role for the Impella(®) left ventricular assist device in this setting, but so far no human data have been published. METHODS: Eight patients with rCA were treated with the Impella CP(®) device at our institution from November 2014 to October 2015. The Impella CP(®) was used at the discretion of the treating physicians in patients with rCA and pulseless electrical activity with presumed primary left ventricular failure...

PURPOSE: Docetaxel is used to treat many cancers, and neutropenia is the dose-limiting factor for its clinical use. A population pharmacokinetic-pharmacodynamic (PK-PD) model was introduced to predict the development of docetaxel-induced neutropenia in Japanese patients with non-small cell lung cancer (NSCLC). METHODS: Forty-seven advanced or recurrent Japanese patients with NSCLC were enrolled. Patients received 50 or 60 mg/m(2) docetaxel as monotherapy, and blood samples for a PK analysis were collected up to 24 h after its infusion...

Medicago ciliaris L., considered as a valuable genetic resource, is a good candidate for the improvement of marginal or degraded lands with low fertility or high salinity. In this study, the pheno-morphological and genetic diversity were investigated in 14 Tunisian populations of M. ciliaris for the first time. Fourteen morphological traits showed significant differentiation between populations and high levels of diversity. Two amplified fragment length polymorphism primer combinations (E-AGC/M-CAA; E-AAG/M-CTG) were analyzed using an automated capillary electrophoresis system...

The geldanamycin derivative 17-allylamino-17-demethoxygeldanamycin (17-AAG) is known to induce internalisation and degradation of the otherwise internalisation-resistant human epidermal growth factor receptor 2 (HER2) receptor. In the present study, 17-AAG was used to increase internalisation of the HER2-specific Affibody molecule ABY-025. The cellular redistribution of halogen-labelled (211)At-ABY-025 and radiometal-labelled (111)In-ABY-025 following treatment with 17-AAG was studied. 17-AAG treatment of SKOV-3 human ovarian carcinoma and SKBR-3 human breast carcinoma cells to some extent shifted the localisation of (111)In-ABY-025 from the cell surface to intracellular compartments in the two cell lines...

: Aag from B. subtilis has been implicated in in vitro removal of hypoxanthine and alkylated bases from DNA. The regulation of expression of aag in B. subtilis, and the resistance to genotoxic agents and mutagenic properties of an Aag-deficient strain were studied here. A strain with a transcriptional aag-lacZ fusion expressed low levels of β-galactosidase during growth and early sporulation but exhibited increased transcription during late stages of this developmental process. Notably, aag-lacZ expression was higher inside the forespore than in the mother cell compartment and this expression was abolished in a sigG-deficient background suggesting a forespore-specific mechanism of aag transcription...

Aminoglycosides (AGs) constitute a major family of potent and broad-spectrum antibiotics disturbing protein synthesis through binding to the A site of 16S rRNA. Decades of widespread clinical use of AGs strongly reduced their clinical efficacy through the selection of resistant bacteria. Recently, conjugation of lipophilic groups to AGs generated a novel class of potent antibacterial amphiphilic aminoglycosides (AAGs) with significant improved activities against various sensitive and resistant bacterial strains...

BACKGROUND: The precise mechanism by which the immune system is adversely affected in cancer patients remains poorly understood, but the accumulation of immune suppressive/pro-tumorigenic myeloid-derived suppressor cells (MDSCs) is thought to be one prominent mechanism contributing to immunologic tolerance of malignant cells in epithelial ovarian cancer (EOC). To this end, we hypothesized genetic variation in MDSC pathway genes would be associated with survival after EOC diagnoses. METHODS: We measured the hazard of death due to EOC within 10 years of diagnosis, overall and by invasive subtype, attributable to SNPs in 24 genes relevant in the MDSC pathway in 10,751 women diagnosed with invasive EOC...

To date, therapeutic drug monitoring (TDM) is carried out with anti-retrovirals and is usually based on total concentrations (Ct). However, for some patients, TDM does not reflect efficacy or the avoidance of toxicity as is the case for atazanavir (ATV), a HIV protease inhibitor. As the unbound concentration (Cu) is the pharmacological active form, the aim of the study was to evaluate the value of Cu and the unbound fraction (fu, fu = Cu / Ct) for the TDM of ATV. The variability of Cu and the corresponding fu of ATV were explored in 43 patients treated with ATV for an average of 13...

PURPOSE: Our study assessed disease-related mortality among Norwegian male military peacekeepers deployed to Lebanon during 1978-1998. METHODS: A total of 21,609 peacekeepers were followed from start of deployment through 2013. Standardized mortality ratios (SMRs) were calculated based on national rates for the overall cohort, by length of time since first deployment to Lebanon, and for service during high- and low-conflict periods. Poisson regression was used to determine the effect of conflict exposure...

HSP90 chaperones are essential regulators of cellular function, as they ensure the appropriate conformation of multiple key client proteins. Four HSP90 isoforms were identified in the protozoan parasite Theileria annulata. Partial characterisation was undertaken for three and localisation confirmed for cytoplasmic (TA12105); endoplasmic reticulum (TA06470) and apicoplast (TA10720) forms. ATPase activity and binding to the HSP90 inhibitor geldanamycin, were demonstrated for recombinant TA12105 and all three native forms could be isolated to varying extents by binding to geldanamycin beads...

Celiac disease (CD) is an autoimmune disease frequently associated with type 1 diabetes (T1D). The prevalence of CD in patients with T1D varies from 3 to 6%. The clinical manifestation of CD in patients with T1D is classified as asymptomatic in about half of cases. Our study aims to determine the frequency of anti-tissue transglutaminase autoantibodies (IgA-tTG) and anti-gliadin antibodies (AGA) in patients with type 1 diabetes in order to early recommend jejunal biopsy and establish a gluten-free diet before the onset of clinical signs and complications of celiac disease...

Translational readthrough of premature termination codons (PTCs) induced by pharmacological compounds has proven to be an effective way of restoring functional protein expression and reducing symptoms in several genetic disorders. We tested the potential of different concentrations of several aminoglycosides (AAGs) for promoting PTC-readthrough in 5 genes involved in the pathogenesis of primary ciliary dyskinesia, an inherited disorder caused by the dysfunction of motile cilia and flagella. The efficiency of readthrough stimulation of PTCs cloned in dual reporter vectors was examined in 2 experimental settings: in vitro (transcription/translation system) and ex vivo (transiently transfected epithelial cell line)...

BACKGROUND: The rarity of mutations in PALB2, CHEK2 and ATM make it difficult to estimate precisely associated cancer risks. Population-based family studies have provided evidence that at least some of these mutations are associated with breast cancer risk as high as those associated with rare BRCA2 mutations. We aimed to estimate the relative risks associated with specific rare variants in PALB2, CHEK2 and ATM via a multicentre case-control study. METHODS: We genotyped 10 rare mutations using the custom iCOGS array: PALB2 c...
