CONTEXT: CYP3A4 and P-gp together form a highly efficient barrier for orally absorbed drugs and always share the same substrates. Our previous work revealed that chrysosplenetin (CHR) significantly augmented the rat plasma level and anti-malarial efficacy of artemisinin (ART), partially due to the uncompetitive inhibition effect of CHR on rat CYP3A. But the impact of CHR on P-gp is still unknown. OBJECTIVE: The present study investigates whether CHR interferes with P-gp-mediated efflux of ART and elucidates the underlying mechanism...

Thorium is natural actinide metal with potential use in nuclear energetics. Contamination by thorium, originated from mining activities or spills, represents environmental risk due to its radioactivity and chemical toxicity. A promising approach for cleaning of contaminated areas is phytoremediation, which need to be based, however, on detail understanding of the thorium effects on plants. In this study we investigated transcriptomic response of tobacco roots exposed to 200μM thorium for one week. Thorium application resulted in up-regulation of 152 and down-regulation of 100 genes (p-value <0...

Chrysomela tremula is a polyvoltine oligophagous leaf beetle responsible for massive attacks on poplar trees. This beetle is an important model for understanding mechanisms of resistance to Bacillus thuringiensis (Bt) insecticidal toxins, because a resistant C. tremula strain has been found that can survive and reproduce on transgenic poplar trees expressing high levels of the Cry3Aa Bt toxin. Resistance to Cry3Aa in this strain is recessive and is controlled by a single autosomal locus. We used a larval midgut transcriptome for C...

How Quaternary climatic and geological disturbances influenced the composition of Neotropical forests is hotly debated. Rain fall and temperature changes during and/or immediately after the Last Glacial Maximum (LGM) are thought to have strongly affected the geographical distribution and local abundance of tree species. The paucity of the fossil records in Neotropical forests prevents a direct reconstruction of such processes. To describe community-level historical trends in forest composition, we turned therefore to inferential methods based on the reconstruction of past demographic changes...

Vitamin K antagonists remain (VKAs) the oral anticoagulant of choice of venous thromboembolic disease. These drugs are characterized by a large inter-individual variability requiring frequent dose tailoring. Genetic polymorphisms for cytochrome CYP2C9 and VKORC1 explain some of the variability, especially in warfarin and acenocoumarol responses. The aim of this study is to assess on cell models the role of ABC transporters in the intestinal transfer of the main coumarin derivatives (warfarin, acenocoumarol) and indanedione derivatives (phenindione, fluindione)...

Introduction: In patients with essential thrombocythemia (ET), the vascular complications contribute to morbidity and mortality. To better predict the occurrence of thrombotic events, an International Prognostic Score for Thrombosis in Essential Thrombocythemia (IPSET-thrombosis) has recently been proposed. We present the application of this score and compare its results with the usual classification system. Method: We retrospectively evaluated the characteristics and risk factors for thrombosis of 46 patients with a diagnosis of ET seen in the last 6 years at Faculdade de Medicina do ABC (FMABC)...

BACKGROUND: Total Knee Arthroplasty (TKA) is a common surgical treatment for severe knee Osteoarthritis (OA), which generally improves pain, physical function, quality of life and possibly fall risk. Fall risk increases for older adults with severe knee OA; however it has not been studied extensively whether this parameter is improved after TKA. OBJECTIVE: To investigate: a) the history and frequency of falls, including mechanism or causes of falls, injuries sustained from falls reported, activity during falling and location of falls and, b) the factors affecting falls, a year after TKA in elderly patients with severe knee OA...

Structural and biochemical features suggest that the almost ubiquitous bacterial YbeY protein may serve catalytic and/or Hfq-like protective functions central to small RNA (sRNA)-mediated regulation and RNA metabolism. We have biochemically and genetically characterized the YbeY ortholog of the legume symbiont Sinorhizobium meliloti (SmYbeY). Co-immunoprecipitation (CoIP) with a FLAG-tagged SmYbeY yielded a poor enrichment in RNA species, compared to Hfq CoIP-RNA uncovered previously by a similar experimental setup...

PURPOSE: MYD88 mutations, notably the recurrent gain-of-function L265P variant, are a distinguishing feature of Activated B-Cell like (ABC) Diffuse Large B Cell Lymphoma (DLBCL), leading to constitutive NFkB pathway activation. The aim of this study was to examine the distinct genomic profiles of MYD88 mutant DLBCL, notably according to the presence of the L265P or other non-L265P MYD88 variants. EXPERIMENTAL DESIGN: A cohort of 361 DLBCL cases (94 MYD88 mutant and 267 MYD88 wild-type) was submitted to next generation sequencing (NGS) focusing on 34 genes in order to analyze associated mutations and copy number variations, as well as gene expression profiling, and clinical and prognostic analyses...

Metal acquisition is crucial for all cells and for the virulence of many bacterial pathogens. In particular, nickel is a virulence determinant for the human gastric pathogen Helicobacter pylori as it is the cofactor of two enzymes essential for in vivo colonization, urease and a [NiFe] hydrogenase. To import nickel despite its scarcity in the human body, H. pylori requires efficient uptake mechanisms that are only partially defined. Indeed, alternative ways of nickel entry were predicted to exist in addition to the well-described NixA permease...

OBJECTIVES: Complete cytoreduction of ovarian cancer often requires excision or ablation of bowel serosa implants. Both argon beam coagulator (ABC) and thermal plasma energy (TPE) (PlasmaJet; PlasmaSurgical, Roswell, Ga) have been used to ablate bowel serosa implants. Our objective was to identify comparable power settings as well as determine the rate of bowel perforation, depth of thermal injury, and extent of inflammatory response with ABC versus TPE in a porcine model. MATERIALS AND METHODS: Nine pigs underwent vaporization of small bowel and colon serosa according to assigned treatment group (TPE vs ABC) and settings (ABC: 30, 50, and 70 W; TPE: Cut 10U, 20U, and 30U and Coagulation 10U, 20U, and 30U)...

We conducted a 6 month, randomized trial of parent training (PT) versus a parent education program (PEP) in 180 young children (158 boys, 22 girls), ages 3-7 years, with autism spectrum disorder (ASD). PT was superior to PEP in decreasing disruptive and noncompliant behaviors. In the current study, we assess moderators of treatment response in this trial. Thirteen clinical and demographic variables were evaluated as potential moderators of three outcome variables: the Aberrant Behavior Checklist-Irritability subscale (ABC-I), Home Situations Questionnaire (HSQ), and Clinical Global Impressions-Improvement Scale (CGI-I)...

Rhinacanthin-C is a major bioactive naphthoquinone ester found in Rhinacanthus nasutus Kurz (Acanthaceae). This compound has potential therapeutic value as an anticancer and antiviral agent. In this study, we investigated an enhancement effect of rhinacanthin-C on doxorubicin cytotoxicity in human breast cancer cell lines and the involvement of the ABC drug efflux transporters. The cytotoxicity was determined by an MTT assay. Combination between doxorubicin and rhinacanthin-C at their non-cytotoxic concentrations when giving each compound alone significantly reduced cell viability in MCF-7 and MCF-7/DOX resistant cells...

PURPOSE: Our objective is to identify the effect of prothrombin complex concentrate (PCC) in acute intracranial hemorrhage (ICH) by evaluating intraparenchymal hematoma expansion between initial and follow-up head CT at 5-24 h, in those with positive CTA spot sign (CTASS). CTASS is an independent predictor of hematoma growth (1). Acute ICH, regardless of etiology, can present with quick mental status decline often resulting in irreversible brain damage. Hematoma expansion appears to be a modifiable predictor of clinical outcome and an appropriate target for medical therapy...
