Epidemiological studies show a reciprocal inverse association between cancer and Alzheimer's disease (AD). The common mechanistic theory for this effect posits that cells have an innate tendency toward apoptotic or survival pathways, translating to increased risk for either neurodegeneration or cancer. However, it has been shown that cancer patients experience cognitive dysfunction pre- and pos...

The successful use of hypermedia systems is often impeded by user disorientation or cognitive overhead caused by the non-linear arrangement of hypertext nodes. In this paper, we address the related problem how a user can be supported in his/her construction of coherence during the navigation through a hyperdocument. Instead of leaving this task to the hypertext author or designer alone, we prop...

In this short paper we introduce a novel data model for multidimensional information, GMD, generalising the MD data model first proposed in [Cabibbo and Torlone, 1998]. The aim of this work is not to propose yet another data model, but to find the most general formalism encompassing all the proposals for a logical data model in the data warehouse field, as for example summarised in [Vassiliadis...

background: recently, we introduced solar related geomagnetic disturbances (gmd) as a potential environmental risk factor for multiple sclerosis (ms). the aim of this study was to test probable correlation between solar activities and gmd with long-term variations of ms incidence. methods: after a systematic review, we studied the association betwee n alterations in the solar wind velocity (vsw...

سابقه و هدف: در سال­ های اخیر روند رو به افزایش تخریب منابع آب، خاک محیط زیست اثر کاربرد بی رویه مواد شیمیایی موجب ترغیب پژوهشگران کشاورزی ارگانیک سال ­های شده است. با وجود همه اثرات مثبتی که ارتباط مصرف آلی بر روی ویژگی­ فیزیکی مطرح است، هنوز این رابطه نگرانی­ زیادی از نظر مسائل زیست­ محیطی، سلامت دارد. بسته منبع، اغلب دارای مقادیر نسبتا عناصر سنگین می باشند؛ بنابراین اندازه گیری دقیق میزان فل...

BACKGROUND AND AIMS Brain dysfunction in functional dyspepsia (FD) has been identified by multiple neuroimaging studies. This study aims to investigate the regional gray matter density (GMD) changes in meal-related FD patients and their correlations with clinical variables, and to explore the possible influence of the emotional state on FD patients's brain structures. METHODS Fifty meal-relat...

The support of effective interaction of the user with the other components of the system is a central problem for information retrieval. In this paper, we present a theory of such interactions taking place within a space of information-seeking strategies, and discuss how such a concept can be used to design for effective interaction. In particular, we propose a model of information retrieval sy...
