Depressive Symptoms and Alcohol Use are Genetically and Environmentally Correlated Across Adolescence
2010
Depressive symptoms and alcohol use are frequently positively associated during adolescence. This study aimed to assess the heritability of each phenotype across adolescence; to assess potential shared liabilities; to examine changes in the nature of shared liabilities across adolescence; and to investigate potential causal relationships between depressive symptoms and alcohol use. We studied a longitudinally assessed sample of adolescent Finnish twins (N = 1,282) to test hypotheses about genetic and environmental influences on these phenotypes within and across ages, using data from assessments at ages 12, 14, and 17.5 years. The heritability of depressive symptoms is consistent across ado…
Expression of liver peroxisomal proteins as compared to other organelle marker enzymes in rats treated with hypolipidemic agents.
1990
Abstract Peroxisome proliferation induced by 2 hypolipidemic agents (clofibrate and ciprofibrate) was studied in rats by complementary approaches, ie cell fractionation, electron microscopy, marker enzyme activities, immunoblotting and nucleic acid hybridization techniques. Administration of clofibrates for 2 and 52 weeks in doses of 500 ppm and 50 ppm respectively, or ciprofibrate for 2,28 and 52 weeks in doses of 250, 25 and 25 ppm respectively, did not alter the behavior of the peroxisomes after induction as shown by ultracentrifugation profiles. The peroxisome mass was increased as shown by the purification procedure. Specific enzymes (catalase and mostly cyanide insensitive palmitoyl C…
Strategic Decisions in Task-Oriented Reading.
2015
AbstractAnswering questions from texts are assessment and instructional activities that are frequently used in schools. Nevertheless, little is known about the strategic processes that students take while performing these tasks. We explored the amount and frequency that students initially read of a text before they answered questions pertaining to the material. In a procedure similar to the one used in the PISA (Program for International Students Assessment), one-hundred-seventy students between 7thand 9thgrade read and answered several questions designed to assess task-oriented reading in three specific texts. We recorded on-line indexes that evaluated student behavior (e.g., the amount of…
"I will never forget him". A qualitative exploration of staff descriptions of helpful relationships in supportive housing.
2020
WHAT IS KNOWN ON THE SUBJECT?: Recovery-oriented studies show that the quality of the professional relationship plays an essential role in the recovery from mental illness. Within mental health care in general, previous studies show that helpful professional relationships are characterized by several reciprocal aspects, such as friendship resemblance and self-disclosure. The literature is scarce on in-depth explorations of professional relationships within the often long-lasting and intimate help context of institutional supportive housing. Explorations of staff members' experiences are absent. The scientific rationale of this study was to expand the current knowledge about professional rel…
Escherichia coli of human and avian origin: detection of clonal groups associated with fluoroquinolone and multidrug resistance in Italy
2012
Objectives: Poultry have been suggested as a reservoir for fluoroquinolone-resistant extraintestinal pathogenic Escherichia coli (ExPEC). Our aim was to investigate whether genotypes associated with ciprofloxacin and multidrug resistance were shared among human and avian E. coli. Methods: We compared 277 human ExPEC isolates from urinary tract infection (UTI) and sepsis (142 susceptible and 135 ciprofloxacin resistant) and 101 avian isolates (68 susceptible and 33 ciprofloxacin resistant) by antimicrobial resistance phenotype, phylogenetic group and multilocus sequence type (ST). Results: Most ciprofloxacin-resistant isolates from both human and avian sources were multidrug resistant. Human…
Need for Conclusive Evidence that Positive and Negative Reciprocity are Unrelated
2013
The strong reciprocity model of the evolution of human cooperation (1) postulates that positive and negative reciprocity are associated. Recently in PNAS, Yamagishi et al. (2) reported results that challenged this proposition by showing that the tendency to reject unfair offers in the ultimatum game is not related to various indicators of positive reciprocity in other experimental games. This result was corroborated by a nonsignificant correlation between self-reported positive and negative reciprocity.
PSA reduction (after antibiotics) permits to avoid or postpone prostate biopsy in selected patients
2007
Microscopic foci of prostatitis may induce prostate-specific antigen (PSA) increase. PSA reduction after antibiotics might identify those patients in whom biopsy can be avoided. Ninety-nine patients received ciprofloxacin for 3 weeks, of whom 59 showed PSA reduction. Histology detected small foci of prostatitis in 65% of cases. Carcinoma was found in 40 and 20.3% of patients with unchanged or decreased PSA, respectively (P=0.03). No cancer was detected if PSA decreased below 4 ng/ml or more than 70%. Biopsy can be postponed, with a low risk of missing a cancer, if PSA decreases more than 70% or below 4 ng/ml.
Differential proto-oncogene mRNA induction from rats treated with peroxisome proliferators
1990
After experimental treatment of rats with clofibrate or ciprofibrate, two peroxisomes proliferators with hypolipidemic activity, RNAs were prepared from liver, kidney, heart and brain; hybridization was done with DNA probes for c-myc and c-Ha-ras oncogenes and for cyanide insensitive Acyl CoA oxidase, a peroxisomal protein. c-myc mRNA is highly abundant in liver and at a lower extent in kidney, especially after treatment with ciprofibrate; clofibrate also allows a c-myc mRNA increase, but at a lower extent. c-Ha-ras, which is already expressed in all tested tissues from control animals, is stimulated by clofibrate and ciprofibrate treatments. Comparatively these compounds stimulate the cyan…
Prevalence and Risk Factors Associated with Use of QT-Prolonging Drugs in Hospitalized Older People
2016
Aims: The objective of this study was to evaluate the prevalence of the prescription of QT-prolonging drugs at hospital admission and discharge and the risk factors associated with their use in older people (aged 65 years and older). Methods: Data were obtained from the REPOSI (REgistro POliterapie SIMI [Società Italiana di Medicina Interna]) registry, which enrolled 4035 patients in 2008 (n = 1332), 2010 (n = 1380), and 2012 (n = 1323). Multivariable logistic regression was performed to determine the risk factors independently associated with QT-prolonging drug use. QT-prolonging drugs were classified by the risk of Torsades de Pointes (TdP) (definite, possible, or conditional) acc…
Peroxisome proliferator-activated receptor α (PPARα) activators induce hepatic farnesyl diphosphate synthase gene expression in rodents
2004
Fibrates are hypolipidemic drugs that exert multiple effects on lipid metabolism by activating peroxisome proliferator-activated receptor alpha (PPARalpha) and modulating the expression of many target genes. In order to investigate the link between PPARalpha and cholesterol synthesis, we analysed the effect of fibrates on expression of the farnesyl diphosphate synthase (FPP synthase) gene, known to be regulated by sterol regulatory element-binding proteins (SREBPs), in conjunction with HMG-CoA reductase. In wild-type mice, both fenofibrate and WY 14,643 induced FPP synthase gene expression, an effect impaired in PPARalpha-null mice. A three-fold induction was observed in ciprofibrate-treate…
