The rapid spread of technological innovations like mobile data services (MDS) has made mobile computing a fact of everyday life for many people. Therefore, we need to understand the contribution of mobile computing to overall quality of life (QoL). Employing the satisfaction hierarchy model and bottom-up spillover theory, this study proposes a theoretical(More)
OBJECTIVE Until now, serum tumor markers, physical examination, and conventional imaging modalities, such as CT or MRI, have been used in assessment of recurrence of cervical cancer after treatment. However, CT and MRI provide only anatomical data, which makes analysis of post-treatment change difficult. This study aims to explore the effectiveness of(More)
The aim of this study is to compare [(18)F]FPEB and [(18)F]FDEGPECO for the quantification of mGlu5 receptors in rodent brains. After preparation of radioligands, dynamic PET data was acquired for 90min. Estimated non-displaceable binding potential (BPND) values were calculated from the non-invasive Logan's graphical analysis method. Although both(More)
BACKGROUND Patients with hormone receptor-positive breast cancer typically show favorable survival. However, identifying individuals at high risk of recurrence among these patients is a crucial issue. We tested the hypothesis that [18F]-fluorodeoxyglucose positron emission tomography (FDG-PET) scans can help predict prognosis in patients with hormone(More)
The aim of this study was to determine whether the brain uptake of [18F]Mefway is influenced by the action of P-glycoprotein (P-gp) and breast cancer resistance protein (Bcrp) in rodents. [18F]Mefway was applied to rats pharmacologically inhibited with tariquidar (TQD) and to genetically disrupted mice. Pretreatment of TQD results in 160 % higher(More)
MUSCLE ATROPHY IS THE RESULT OF TWO OPPOSING CONDITIONS THAT CAN BE FOUND IN PATHOLOGICAL OR DISEASED MUSCLES: an imbalance in protein synthesis and degradation mechanisms. Thus, we investigated whether exogenous melatonin could regulate muscle components in stroke-induced muscle atrophy in rats. Comparing muscle phenotypes, we found that long-term(More)
Stress affects the serotonergic system, which is associated with depression. Previous research has showed that chronic stress causes the deactivation of the limbic system. However, the influence of the acute physical stress on the serotonergic system in vivo was primarily unclear. The purpose of this research is to elucidate the effects of the acute(More)
Depression frequently accompanies in Parkinson's disease (PD). Previous research suggested that dopamine (DA) and serotonin systems are closely linked with depression in PD. However, comprehensive studies about the relationship between these two neurotransmitter systems are limited. Therefore, the purpose of this study is to evaluate the effect of(More)
In this paper, we describe a user study evaluating the usability of an augmented reality (AR) multimodal interface (MMI). We have developed an AR MMI that combines free-hand gesture and speech input in a natural way using a multimodal fusion architecture. We describe the system architecture and present a study exploring the usability of the AR MMI compared(More)
