Parenting is linked to conduct disorders (CD) and substance related disorders (SRD) in adolescents, but with differences according to cultural context. A questionnaire with two versions (parenting questionnaire TXP-A for adolescents and TXP-C  for primary caregivers) was designed using the Delphi method to evaluate parenting practices related to CD and SRD in a Spanish population. It was validated in a community sample of 631 adolescents aged between 14 and 16 and their caregivers. Results suggest a 29-item TXP-A questionnaire with bifactorial structure: affection-communication and control-structure, with high internal (Cronbach’s alpha=0...

One of the primary goals of biological assessment of streams is to identify which of a suite of chemical stressors is limiting their ecological potential. Elevated metal concentrations in streams are often associated with low pH, yet the effects of these two potentially limiting factors of freshwater biodiversity are rarely considered to interact beyond the effects of pH on metal speciation. Using a dataset from two continents, a biogeochemical model of the toxicity of metal mixtures (Al, Cd, Cu, Pb, Zn) and quantile regression, we addressed the relative importance of both pH and metals as limiting factors for macroinvertebrate communities...

BACKGROUND: Low birth weight (LBW) is associated with reduced nephron endowment. Clinical-pathologic features of post adaptive focal segmental glomerulosclerosis (FSGS) have been observed in subjects with prematurity and very LBW. METHODS: We aimed to investigate the correlation between LBW and outcome in a cohort of 89 children with idiopathic nephrotic syndrome (NS) (2-12 years-old at onset, followed for > 3 years), of whom 21 with LBW (birth weight < 10th percentile for gestational age, gender, ethnicity, and maternal parity or birth weight < 2500 g)...

Arbuscular mycorrhizal (AM) fungi play an important role in plant tolerance of heavy metal contamination. In this study, a pot experiment was conducted to illustrate the effects of the two AM fungi species Funneliformis mosseae (Fm) and Rhizophagus irregularis (Ri) on plant growth of Oryza sativa L. either with or without ethylenediamine tetraacetate (EDTA) addition and during exposure to five Cd concentrations (in the range of 0-5 mg kg-1). The results showed that Fm inoculation achieved greater mycorrhizal colonization and mycorrhizal dependency indexes than Ri inoculation...

We investigate the mechanisms underlying the reconfiguration of random aggregates of spheres through capillary interactions, the so-called "colloidal recycling" method, to fabricate a wide variety of patchy particles. We explore the influence of capillary forces on clusters of deformable seed particles by systematically varying the crosslink density of the spherical seeds. Spheres with a poorly crosslinked polymer network strongly deform due to capillary forces and merge into large spheres. With increasing crosslink density and therefore rigidity, the shape of the spheres is increasingly preserved during reconfiguration, yielding patchy particles of well-defined shape for up to five spheres...

Cadmium (Cd) is a pollutant with multiple adverse health effects: cancer, renal dysfunction, osteoporosis and fracture, and cardiovascular disease. Several population-based studies found an association between Cd and diabetes mellitus (DM), but this association is inconsistent with other research. We conducted meta-analysis to examine relationship between urinary/blood Cd exposure and DM risk. Pertinent studies were identified by searching PubMed and Embase databases, and combined odds ratio (OR) and corresponding 95% confidence interval (CI) were applied to evaluate said association...

OBJECTIVE: Social-cognitive information processing, social skills, and social interactions are problem-maintaining variables for aggressive behavior in children. We hypothesized that these factors may be possible mediators of the mechanism of change in the child-centered treatment of conduct disorders (CDs). The aim of the present study (Clinical trials.gov Identifier: NCT01406067) was to examine putative mechanisms of change for the decrease in oppositional-defiant behavior resulting from child-centered treatment of patients with oppositional-defiant disorder (ODD) or CD...

OBJECTIVES: Inflammatory bowel diseases (IBD), comprised of Crohn's disease (CD) and ulcerative colitis (UC), are characterized by a complex pathophysiology that is thought to result from an aberrant immune response to a dysbiotic luminal microbiota in genetically susceptible individuals. New technologies support the joint assessment of host-microbiome interaction. METHODS: Using whole genome sequencing and shotgun metagenomics, we studied the clinical features, host genome, and stool microbial metagenome of 85 IBD patients, and compared the results to 146 control individuals...

BACKGROUND: Celiac disease (CD) occurs in subjects positive for HLA-DQ2 and/or DQ8 gene loci at any age following ingestion of gluten-containing food. An increased permeability of the mucosa allows interactions between gliadin macromolecules and genetic factors. It has been observed that Helicobacter pylori has the ability to modulate the integrity of the duodenal epithelium. We aimed to determine whether H. pylori infection may enhance the occurrence of CD in genetically susceptible subjects...

Cluster of differentiation (CD)133 is considered a molecular marker of cancer stem cells in hepatocellular carcinoma. In the present study, the effect of lidamycin (LDM) on CD133 expression in hepatocellular carcinoma (Huh7 cells) was evaluated and the potential molecular mechanism was investigated. Flow cytometry analysis, as well as sorting, sphere formation and western-blot assays, were performed in vitro to explore the effects of LDM on CD133 expression. A subcutaneous tumor model in nude mice was used to observe the effects of LDM on tumor volume and CD133 protein in vivo...

describe a novel hybrid tumor-specific promoter, ARE-hTERT, composed of the human TERT gene promoter (hTERT) and the antioxidant response element (ARE) from the human GCLM gene promoter. The hybrid promoter retains the tumor specificity of the basal hTERT promoter but is characterized by an enhanced transcriptional activity in cancer cells with abnormal activation of the Nrf2 transcription factor and upon induction of oxidative stress. In the in vitro enzyme-prodrug cancer gene therapy scheme, ARE-hTERT promoter-driven expression of CD : UPRT (yeast cytosine deaminase : uracil phosphoribosyltransferase) chimeric protein induced a more pronounced death of cancer cells either upon treatment with 5-fluorouracil (5FC) alone or when 5FC was combined with chemotherapeutic drugs as compared to the hTERT promoter...
