| We have evaluated the clinical impact of FDG-PET on patient staging and management during the opening year of our PET centre in France. A questionnaire, translation in French of the questionnaire used recently in California, was sent to the referring physician of each of the 476 patients who had at least one routine FDG-PET examination during the year 2000. Of 348 responses (response rate = 73%), the disease was upstaged in 26% of the cases and downstaged in 9%. Inter-modality management changes (change from a scheduled therapeutic modality for a different one) were reported in 37% of the cases and intra-modality changes in 9%. Those modification rates... |

| Robust and versatile perception of the world is augmented considerably when information from our five separate sensory systems is combined. Much recent evidence has demonstrated near-optimal integration across senses, but it remains unclear at what level the integration occurs, at a "sensory" or "decisional" level. Here we show that non-informative "pedestal" motion stimuli in one sensory modality (vision or touch) selectively lowers thresholds in the other, to the same degree as pedestals in the same modality: strong evidence for functionally important cross-sensory integration at early levels of sensory processing. |

| How does attention modulate sensory representations? In order to probe the underlying neural mechanisms, we established a simple rodent model of modality-specific attention. Here we describe results of experiments in freely moving rats in which we have used tetrodes to record neural responses in primary auditory cortex (area A1) while subjects performed this behavior.

Subjects were first trained to perform distinct auditory and olfactory two alternative forced-choice (2AFC) tasks. Training and testing were conducted in a custom three-poke computer-controlled behavioral apparatus. Subjects initiated trials with a center-poke, which triggered presentation of a tone (either 5 or 15 Hz), an... |

| Tourism in rural space is a tourism modality which has lately been the focus of investors and students. However there has been little spread of studies focusing such modality, featuring the characteristics of the industry to which it belongs, showing up-to-date discussions and world trends. So, this study, concerned as it is with it, has gathered information on such points and shows that, world-widely, tourism in rural space is an alternative modality that arose in counter-position to mass tourism, has been seen as a solution to poorer regions and, because of this, has been the aim of many investors and students. The industry to which it belongs features... |

| How does attention modulate sensory representations? In order to probe the underlying neural mechanisms, we established a simple rodent model of modality-specific attention. Rats were trained to perform distinct auditory two-tone discrimination and olfactory odor discrimination in a two alternative choice (2AC) paradigm. 
To determine auditory cortex’s role in this frequency discrimination task, we used GABA-A receptor agonist muscimol to transiently and reversibly inactivate auditory cortexes bilaterally in rats performing simple interleaved auditory and olfactory discrimination. With olfactory discrimination performance serving as internal control for motivation and decision making capability,... |

| The increase and flexibilization of e-learning in Brazil has generated concern about the low capacity to ensure the quality of institutions and courses. The objective is to identify the literature on experiences of pharmaceutical e-learning. A scope review was carried out, mapping key concepts and evidence. The selected articles, without period restriction, from the Scielo, Pubmed and Scopus databases provided data on the educational level of experience, modality, workload, content delivery method, instruments used, types of topics, evaluation information and purpose of the study. There were 87 articles on preparation for subsequent classes; feedback or continuation of previous classes; to specific training; the comparison... |

| A hospital based prospective study was conducted from July 2001 to July 2015 at the Department of Radiology, Jordan University Hospital, Amman, Jordan. During that period, five cases of double inferior vena cava (DIVC) were discovered among a cohort of 7722 patients (3861 men and 3861 women, 49.5±16.9 years, range 1678 years). Cases were diagnosed by contrast-enhanced Spiral CT venography (CTV) and confirmed by turbo three-dimensional (3D) time-of-flight contrast-enhanced MR venography. The majority of patients 3166 (41 %) were referred for staging and follow-up of malignancy, postoperative complications 1777 (23 %), non-specific abdominal pain 1467 (19 %), preoperative assessment 849 (11 %) and trauma 463 (6 %). Magnetic resonance venography showed... |

| In the initial stage, the status quo of aquatic products industry in Taiwan and Zhoushan is analyzed. The aquatic products industry in Taiwan is characterized by high input, high output, advanced fishery import and export trade, refined and specialized fishery organizations and the dominant role played by the government. However, in Zhoushan, there are many problems in the development of aquatic products industry, featuring weak brand consciousness, inadequate famous brand and pillar industries, frequently restricted by green trade barrier and disordered competition of aquatic products market. The comparative advantages of aquatic products Cross-Straits are measured by using revealed comparative advantage index (RCA) and trade specialized index (TSC), the... |

| Positron emission tomography (PET) is an imaging modality that gives information on tissue metabolism and functionalism, different from other imaging techniques like computed tomography (CT) and magnetic resonance imaging (MRI), which provide anatomical or structural information. PET has reached its development in biomedical research because of its capacity to use analogous compounds of many endogenous substance as tracers, and to measure, in vivo and in a non-invasive way, their consumption by the different organs and tissues of the mammalian body. Fluordeoxyglucose-F18 (FDG) PET has been proven to be a tracer adequate for clinical use in oncology and in many neurological diseases, with an excellent cost-efficiency ratio.... |

| V-1 Immunitor (V1) is an oral AIDS vaccine currently being used as a therapeutic modality by HIV-positive patients. Upon interim analysis of phase I safety trial it has been discovered that patients who had elevated liver enzymes aspartate (AST/SGOT) and alanine (ALT/SGPT) aminotransferases have experienced the reduction of enzyme levels back to normal. Two other hepatitis markers alkaline phosphatase and bilirubin have also decreased. V1s effect may be hepatitis-specific since liver enzymes in normal patients treated with V1 have not changed and three patients who were Hepatitis B antigen positive at baseline became negative after therapy. The results suggest that V1 supplementation reduces hepatic damage caused by... |

| The contemporary education process is necessary tied to information-technology and to Informatic. By using the Internet as source and as knowledge’s transmission modality one modifies the learning parameters. From the quantitative point of view, the Informatic increases the education process efficiency. From the qualitative point of view, the Informatic imposes a change of the education paradigm. The Informatic determines status modifications for the purveyor and for the beneficiary of the knowledge. The Informatic modifies the psychosocial characteristics of the knowledge process too. Using the Internet supposes the assumption of at least two levels reality. A more than one level reality representation agrees with the... |

| This paper uses a unique panel data set from Ethiopia to examine the determinants of participation in and receipts of food aid through free distribution (FD) and food-for-work (FFW). Results show that aggregate rainfall and livestock shocks increase household participation in both FD and FFW. FFW also seems well-targeted to asset-poor households. The probability of receiving FD does not appear to be targeted based on household wealth, but FD receipts are lower for wealthier households. The effects of FD and FFW on child nutritional status differ depending on the modality of food aid and the gender of the child. Both FFW and FD have a positive direct impact on weight-for-height. Households invest proceeds from FD in girls’... |
