Introduction: The best outcome for patients with prostate cancer (PCa) is seen for those treated at an early stage of the disease. A digital rectal examination (DRE) and the measurement of serum prostate specific antigen (PSA) levels are the current standards for PCa early detection. However, serum PSA testing lacks both sensitivity and specificity, and core biopsies frequently fail to identify small foci of PCa. The availability of non-invasive diagnostic molecular tests that could allow for a more precise identification of malignant prostate cells in asymptomatic men would be of great clinical value to improve PCa diagnosis. Study design: 114 men scheduled to undergo a prostate biopsy were enrolled in the study. The biopsies were triggered either by an abnormally high PSA value or by suspicious findings on DRE. Patients with other known or suspected urinary malignancy were excluded from the study. Morning, post-prostate massage and post-biopsy urine samples were collected from all individuals. The main goals of this study were a) to determine if prostate massage can improve the prostate DNA quantity compared to urine collected in the morning or after biopsy, and b) to evaluate the methylation status of a gene panel in urine samples from subjects with cancer found in prostate biopsy tissue cores versus subjects without cancer. Methods: Gene promoter methylation is associated with prostate cancer and has been successfully used for the molecular detection of neoplasia in urine. We have developed real-time methylation specific PCR assays to define the methylation status of several genes. Results: Median age of the patients was 65 years (range 48-85). PCa was found in 51% of the patients. Histological diagnosis of the biopsies was compared to methylation results in urine from 102 samples (89% success rate due low DNA yields for 12 samples). The comparison between different urine sampling techniques showed that prostate massage is needed. The best results were obtained in post massage urine samples with a combination of GSTP1, p14, p16, RARβ2 and RASSF1A resulting in a sensitivity of 74% and a specificity of 75%. Future: A multiplex assay using the Cepheid SmartCycler™ II platform is under development. Further studies are in progress to validate the assay across multiple centers. [less ▲]

Abstract of Background Paper: Background: While documentation of clinical aspects of General Practice/Family Medicine (GP/FM) is assured by the International Classification of Primary Care (ICPC), there is no taxonomy for the professional aspects (context and management) of GP/FM. Aim: To present the development, dissemination, applications, and resulting face validity of the Q-Codes taxonomy specifically designed to describe contextual features of GP/FM, proposed as an extension to the ICPC Development: The Q-Codes taxonomy was developed from Lamberts’ seminal idea for indexing contextual content (1987) by a multi-disciplinary team of knowledge engineers, linguists and general practitioners, through a qualitative and iterative analysis of 1702 abstracts from six GP/FM conferences using Atlas.ti software. A total of 182 concepts, called Q-codes, representing professional aspects of GP/FM, were identified and organised in a taxonomy. Dissemination: The taxonomy is published as an on-line terminological resource, using semantic web techniques and Web ontology language (OWL) (www.hetop.eu/Q). Each Q-code is identified with an Unique Resource Identifier (URI), and provided with preferred terms, formal definitions in eight languages (pt, es, en, fr, nl, ko, vi, tr) and search filters for Medline and web searches. Applications. . This taxonomy has already been used to support queries in bibliographic databases (e.g. Medline), to facilitate indexing of grey literature in GP/FM as congress abstracts, master theses, websites and as an educational tool in vocational teaching, Conclusions: The rapidly growing list of practical applications provides face-validity for the usefulness of this freely available new terminological resource.

Poor quality antimalarial drugs are one of the public’s major health problems in Africa. The depth of this problem may be explained in part by the lack of effective enforcement and the lack of efficient local drug analysis laboratories. To tackle part of this issue, two spectroscopic methods with the ability to detect and to quantify quinine dihydrochloride in children’s oral drops formulations were developed and validated. Raman and Near Infrared (NIR) spectroscopy were selected for the drug analysis due to their low cost, non-destructive and rapid characteristics. Both of the methods developed were successfully validated using the total error approach in the range of 50-150% of the target concentration (20% W/V) within the 10% acceptance limits. Samples collected on the Congolese pharmaceutical market were analyzed by both techniques to detect potentially substandard drugs. After a comparison of the analytical performance of both methods, it has been decided to implement the method based on NIR spectroscopy to perform the routine analysis of quinine oral drop samples in the Quality Control Laboratory of Drugs at the University of Kinshasa (DRC).

The distribution of interstitial collagen types I and III was studied by immunocytochemistry in the mesenchyme of progressing and regressing mesonephric and paramesonephric ducts of male and female rat fetuses from the age of 15 days until birth. Immunocytochemistry revealed a collagen-poor mesenchymal area around the genital ducts and in continuation with the coelomic epithelium on the lateral edge of the mesonephric ridge of 15-day-old fetuses. Ultrastructurally, collagen fibrils were accumulated along the continuous lamina densa of the mesonephric ducts, whereas they were absent on the medial side of the male and female paramesonephric ducts. In males, the amount of collagen fibrils increased with the histological maturation of the mesenchyme around the mesonephric duct, whereas around the regressing paramesonephric duct collagens disappeared from the basement membrane region and the surrounding mesenchyme of the 16-day-old male duct. After the completion of the paramesonephric regression, the mesenchyme acquired a uniformly collagen containing interstitial matrix. In females, the collagens increased in the mesenchyme around the progressing paramesonephric duct, and the original site of the regressing mesonephric duct became occupied with a collagen-containing mesenchyme by the age of 19 days. The results suggest a close structural linkage between the mesonephric duct and the established early paramesonephric duct. The differences in the developmental maturation of the periductal mesenchyme and the observed changes in the composition of the interstitial matrix probably reflect the functional differences in the regulatory factors acting on the progression and regression of the male and female genital ducts.

The sheepshead minnow is widely used in ecotoxicological studies and such investigations have begun to focus on potential disruption of the thyroid axis. However, normal levels of thyroxin (T4) and 3,5,3’-triiodothyronine (T3) and their developmental patterns are unknown. This study set out to determine the profiles of whole-body thyroxin (T4) and 3,5,3'-triiodothyronine (T3) levels during the development of sheepshead minnow from embryo to juvenile and adults. Couples of three females and two males were placed in breeding chambers designed for this experiment. More than 1000 eggs were collected and maintained in seawater. Embryos were selected under a dissection microscope and placed in incubation dishes (50 per dish) at 25°C. On day 8, embryos hatched and larvae were transferred to 1L beakers. For one week after hatching, larvae were fed on artemias and from 8 to 30 days post-hatch they were fed on flaked fish food. Embryos were sampled on day 0, 2, 4, 6 post-fertilization and larvae and juveniles were sampled every three days from day 0 to 28 days post-hatch. The pooled samples were taken from several incubation dishes and divided in three replicate batches of 30 individuals. Enzyme-linked immunoassay were used and validated for analysis of T4 and T3 after extraction from whole fish. At each sampling point 5 individuals were placed in formalin fixative for histology. Length and body mass were measured. Hatching success, gross in vivo observations, thyroid hormone levels and histology data will be determined and discussed in the framework to characterize the profiles of thyroid hormone levels during the development of sheepshead minnow from embryo to adult. This study establishes a baseline for thyroid hormones in sheepshead minnows, which will be vital for the understanding of thyroid hormone functions and in future studies of thyroid toxicants in this species.

The function of the phosphoinositide 5-phosphatase Ship2 was investigated in a new mouse model expressing a germline catalytically-inactive Ship2∆/∆ mutant protein. Ship2∆/∆ mice were viable with defects in somatic growth and in development of muscle, adipose tissue and female genital tract. Lipid metabolism and insulin secretion were also affected in these mice, but glucose tolerance, insulin sensitivity and insulin-induced PKB phosphorylation were not. We expected that the expression of the catalytically inactive Ship2 protein in PI 3’-kinase-defective p110αD933A/+ mice would counterbalance the phenotypes of parental mice by restoring normal PKB signaling but, for most of the parameters tested, this was not the case. Indeed, often, the Ship2∆/∆ phenotype had a dominant effect over the p110αD933A/+ phenotype and, sometimes, there was a surprising additive effect of both mutations. p110αD933A/+Ship2∆/∆ mice still displayed a reduced PKB phosphorylation in response to insulin, compared to wild type mice yet had a normal glucose tolerance and insulin sensitivity, like the Ship2∆/∆ mice. Together, our results suggest that the Ship2∆/∆ phenotype is not dependent on an overstimulated class I PI 3-kinase-PKB signaling pathway and thus, indirectly, that it may be more dependent on the lack of Ship2-produced phosphatidylinositol 3,4-bisphosphate and derived phosphoinositides.

Rationale: The maturing adolescent brain has been suggested to be more sensitive than the adult brain to ethanol-induced neuroadaptations. In animal studies, sensitization to the stimulant effects of ethanol is used to study the vulnerability to chronic ethanol-induced neurobehavioral alterations. Objectives: The aim of the present study was to systematically characterize age-dependent changes in the development and expression of the sensitization to the stimulant effects of a range of ethanol doses in female Swiss mice. Three ages were studied: 21-day-old mice (postweanlings), 35-day-old mice (adolescents), and 63-day-old mice (adults). Methods: Postweanling, adolescent, and adult mice were daily injected with saline or various ethanol doses (1.5 to 4 g/kg) for 7 days. They were then tested for acute and sensitized locomotor activity. Results: Postweanling and adolescent mice were more sensitive than adult mice to the acute stimulant effects of ethanol. In adult mice, daily injections of ethanol at doses between 2.5 and 4 g/kg led to significant sensitization. Higher ethanol doses (3.5 and 4 g/kg) were required to induce sensitization in postweanling and adolescent mice. However, younger mice showed ethanol sensitization of higher magnitude. Conclusions: Young mice develop very strong ethanol sensitization at doses that mimic binge drinking in humans. These results might explain why early ethanol drinking during adolescence is related to a higher prevalence of subsequent alcohol disorders. [less ▲]
