In this paper, we empirically examine how the revenue model (paid, free, or freemium) adopted for a given app affects the app revenue performance as measured by the app daily revenue rank. We also study the impact of in-app purchase on this measure of performance. Moreover, we study how such relationships are contingent upon the distribution platform where the app is marketed as well as the typ...
This review describes a molecular mechanism for regulation of one pathway of microbial assimilation of iron, an element which may well be a nutrient required by all living cells. Unlike organic compounds, minerals cannot be synthesized and must be acquired from the environment. In contrast to amino acids, fatty acids, and monosaccharides, all of which can be accumulated in the form of relativel...
BACKGROUND Iron is essential for many physiological processes; whereas, iron overload has been known as a risk factor in progression of atherosclerosis. The aim of this study was to investigate the importance of serum ferritin levels, which are known as an indicator of body iron stored in the incidence of coronary artery disease (CAD). METHODS In a case-control study, we evaluated 432 eligibl...
building retailer equity increases revenue and profitability by insulating retailers from competitors. store image is the basis of retailer equity, but extant literature offers little in sight in to the empirical research which takes store image dimensions as antecedents of retailer equity. this paper establishes a theoretical and empirical basis that shows the impact of selected store image di...
Depressive symptoms have become the most important global public health issue. Iron plays an important role in brain function, cognition, and behavior, and its impacts on depressive symptoms may be multifactorial with both positive and negative effects. Previous observational studies focusing on the association between iron status and depressive symptoms showed inconsistent results. Ferritin is...
Ferritin is a ubiquitous intracellular protein that can store and release iron and act as a buffer against iron deficiency and iron overload. Ferritin is widely used as a clinical biomarker to evaluate iron status. Increased serum ferritin concentrations have been reported to be associated with metabolic syndrome (MetS) features. However, serum ferritin concentrations differ significantly accor...
Beta thalassaemia major is a common hereditary haematological disease in southern Chinese. Advances in transfusion and iron chelation improve survival but haematopoietic stem cell transplantation (HSCT) is still the only curative treatment. Due to repeated blood transfusion and iron overload, thalassaemia patients undergoing HSCT are at a higher risk of graft rejection and transplant-related mo...
Most methanogenic archaea reduce CO(2) with H(2) to CH(4). For the activation of H(2), they use different [NiFe]-hydrogenases, namely energy-converting [NiFe]-hydrogenases, heterodisulfide reductase-associated [NiFe]-hydrogenase or methanophenazine-reducing [NiFe]-hydrogenase, and F(420)-reducing [NiFe]-hydrogenase. The energy-converting [NiFe]-hydrogenases are phylogenetically related to compl...
Genes in the ZIP family encode transcripts to store and transport bivalent metal micronutrient, particularly iron (Fe) and or zinc (Zn). These transcripts are important for a variety of functions involved in the developmental and physiological processes in many plant species, including most, if not all, Poaceae plant species and the model species Arabidopsis. Here, we present the report of a ge...
