The alternative strategy to address social inequality and lack of student learning outcomes are modelsof cooperative learning. There are several models that made the researchers are interested in knowingthe signi.. cance of the difference to the learning outcomes and student activities, namely the model ofSTAD and TGT.The design of this research is quantitative research with this type of quasi-experimentalwith the factorial design version of nonequivalent control group design 2x2 (Tuckman, 1999). Based ondata from pretest and posttest scores can be seen that a good learning outcomes for grade STAD andTGT have increased, the increase amounted to 22.73% STAD class and class TGT by 20.91%. STADclass has increased by 1.82% higher than TGT class. Similarly, in the students\u27 learning activities,STAD model to get the student activity by 82.44% and amounted to 80.91% of IGT. STAD class rose1.53% higher than TGT class. Based on the hypothesis test concluded that (1) there is no signi.. cantdifference in learning outcomes between the application of the model STAD and TGT, and (2) there is nosigni.. cant difference in learning activities between the application of the model STAD and TGT. Bothmodels are equally able to bene.. t in improving student learning outcomes and student activity. In thisstudy, there is no one model that can be said to be superior significantly from one another

Guanylate cyclase C as a target for prevention, detection, and therapy in colorectal cancer.

INTRODUCTION: Colorectal cancer remains the second leading cause of cancer death in the United States, and new strategies to prevent, detect, and treat the disease are needed. The receptor, guanylate cyclase C (GUCY2C), a tumor suppressor expressed by the intestinal epithelium, has emerged as a promising target. Areas covered: This review outlines the role of GUCY2C in tumorigenesis, and steps to translate GUCY2C-targeting schemes to the clinic. Endogenous GUCY2C-activating ligands disappear early in tumorigenesis, silencing its signaling axis and enabling transformation. Pre-clinical models support GUCY2C ligand supplementation as a novel disease prevention paradigm. With the recent FDA approval of the GUCY2C ligand, linaclotide, and two more synthetic ligands in the pipeline, this strategy can be tested in human trials. In addition to primary tumor prevention, we also review immunotherapies targeting GUCY2C expressed by metastatic lesions, and platforms using GUCY2C as a biomarker for detection and patient staging. Expert commentary: Results of the first GUCY2C targeting schemes in patients will become available in the coming years. The identification of GUCY2C ligand loss as a requirement for colorectal tumorigenesis has the potential to change the treatment paradigm from an irreversible disease of genetic mutation, to a treatable disease of ligand insufficiency

Each of these processes is laden with wastes that adversely affect project performance. Therefore, this study seeks to identify such wastes so as to develop a mechanism for its effective management. To achieve this, action research study will be conducted in some consulting engineering firms situated in Bloemfontein, South Africa. It is expected that the results will provide the platform for the development of a suitable mechanism for reduction / elimination of wastes in structural design process

Analyse De L’évolution Saisonnière Des Matières Oxydables Dans Le Secteur Oriental De La Lagune Ebrié (Côte d’Ivoire)

Faced with the extension of the cities of Grand-Bassam and Abidjan along the Ebrié lagoon and the lack of data on the oxidizable content in the eastern sector of the Ebrié lagoon, this study was initiated. It aims to determine the levels of oxidizable materials in the eastern sector of the Ebrié lagoon. PH, temperature, salinity and dissolved oxygen were determined in situ at thirtyone (31) stations during the dry season and the rainy season. On these same stations, water samples were also taken per season to determine the content of oxidizable matter according to the methods in force. The statistical treatment consisted in knowing the links between the hydrological parameters. The average values of the parameters in the rainy season and in the dry season are 5,98 and 7,28 respectively for the pH, 27,59 °C and 29,6 °C for the temperature, 5,01 and 19,48 for salinity, 6.14 mg/L and 3.78 mg/L for dissolved oxygen, 0.24 mg/L and 0.38 mg/L for ammonium, 0.089 mg/L and 0.036 mg/L for nitrite, 8.18 mg/L and 0.23 mg/L for nitrate, 1.57 mg/L and 1.78 mg/L for orthophosphate, 76.06 mg/L and 56.81 mg/L for COD and 40.23 mg/L and 34.16 mg/L for BOD5. The evolution of oxidizable matter depends on the entry of continental, oceanic and precipitation waters into the lagoon. The high levels of oxidizable materials are observed in large part in the berries. Good positive correlations are observed between COD and DBO5 and between salinity and nitrite. Temperature and salinity have a good negative correlation. Lagoon waters receive more oxidizable materials in highly urbanized areas than in areas with little or no urbanization

The effect of ruminal incubation of bioactive yeast (Saccharomyces cerevisiae) on potential rumen degradability of Panicum maximum and Centrosema pubescens in West African dwarf sheep

The rising interest in the use of organic and inorganic substances in manipulating rumen function for improved fermentative activity has provided avenues for the inclusion of various species of yeast cultures in ruminant diets. In this study, we investigated the effect of bioactive yeast (Saccharomyces cerevisiae), on rumen degradative function of the West African Dwarf Sheep (WADS) in terms of fermentable organic matter, crude protein and crude fiber of Panicum maximum and Centrosema pubescens. Three inclusion levels of Saccharomyces cerevisiae, 200, 500 and 800 milligrams were infused into the rumen of three groups (A, B and C), of three WAD sheep each. Another group (D) of same animal number served as the control. In vivo rumen potential degradability studies, using the nylon bag technique was performed using Panicum maximum and Centrosema pubescens in all the groups. The result of the study showed  that bioactive yeast improved the potential rumen degradability of crude protein, crude fibre and organic matter fractions of Panicum maximum and Centrosema pubescens in a rather dose dependent manner compared to the control. There was a significant correlation (r = 0.56) between degradability, dose and time of incubation for crude fibre and organic  matter fractions but not for crude protein. These observations suggest that regulated dietary inclusion of bioactive yeast can be used to bioengineer the rumen towards efficient fibre breakdown, particularly forages of poor protein quality and high fibre content, for efficient production of volatile fatty acids as well as probably enhancing other aspects of rumen functions.Keywords: Bioactive Yeast, Degradability, Forages, Rumen, WADS

Distribution et incidence de la mosaïque du concombre (cmv) dans des bananeraies industrielles au sud-est de la côte d’ivoire.

La distribution et l’incidence du virus de la mosaïque du concombre (CMV) infectant le bananier ont été évaluées dans les bananeraies au Sud-Est de la Côte d’Ivoire. Pour ce faire, des prospections ont été effectuées dans des plantations industrielles des secteurs de Niéky (Dabou); Banacomoé (Abengourou) et Grand-fleuve (Tiassalé). Des données de relevés phytosanitaires relatives au CMV ont été recueillies et des échantillons de feuilles symptomatiques et asymptomatiques de bananiers de la variété ‘‘Grande naine’’ ont été collectés. Des diagnostics sérologiques utilisant les tests DAS-ELISA (Double Antibody Sandwich Enzyme Linked  Immunosorbent Assay), ont permis de confirmer la présence du CMV dans ces échantillons. Dans la pépinière du secteur Banacomoé, le CMV a été diagnostiqué dans environ 50 % de lots de plantules issus de micropropagation (vitroplants). L’incidence de la maladie enregistrée sur la base des symptômes observés dans les trois secteurs indiquent un taux variant de 5 % à 25 % avec une prédominance (66,25 %) des symptômes sévères (pourriture du coeur) sur les plants de 3 mois d’âges. Cependant, les plantations de plus de trois mois d’âge et les plants de la collection in vivo de pieds mères utilisés pour la micropropagation n’ont présenté que de rares plants infectés. La répartition du CMV dans les plantations de  moins de 3 mois a révélé une prédominance des foyers d’infection de type marginal.Mots clés : Cucumber Mosaic Virus, DAS-ELISA, incidence, distribution, Musa spp., Côte d’IvoireThis survey has been carried out in order to study the incidence and distribution of the Cucumber Mosaic Virus (CMV) infecting banana in the South-East part of Côte d’Ivoire. For this purpose, an assessment was conducted in the zones of Niéky (Dabou); Banacomoé (Abengourou) and Grand-fleuve (Tiassalé), in order to gather phytosanitary data concerning the occurrence of the CMV in the nursery and fields. Banana leaf samples of the ‘‘Grande naine’’variety showing CMV symptoms and some without symptom were collected. The presence of the virus has been confirmed by serological tests using DAS-ELISA (Double Antibody Sandwich Enzyme  Linked Immunosorbent Assay). About 50 % of the tissue culture derived banana batches composing the nursery in a plantation of Abengourou was found to be infected by CMV. Based on symptoms observed, the incidence of the disease in these production sectors visited, varied from 5 % to 25 % with a predominance (66,25 %) of severe symptoms (heart-rot, symptoms) on plants of less than 3 month of age. However, plants beyond three months showed less CMV infected plants and less severe symptoms. Similarly, only few plants were infected in the germplasm containing mother plants used for micropropagation. In the field, banana plants showing CMV symptoms were more frequently distributed at the edge of the fields
