In this paper, we explore how supply chain theorists can engage with metaphorical imagination to develop theory. Our main purpose was provide additional useful guidance on scholars approach the method of metaphoric transfer. To do this, build previous work transfer and Metaphoric Transfer Pathways framework. The framework offers two novel approaches working metaphors that will help best leverag...

In Drosophila, pulsed production of the steroid hormone ecdysone plays a pivotal role in developmental transitions such as metamorphosis. Ecdysone production is regulated in the prothoracic gland (PG) by prothoracicotropic hormone (PTTH) and insulin-like peptides (Ilps). Here, we show that monoaminergic autocrine regulation of ecdysone biosynthesis in the PG is essential for metamorphosis. PG-s...

Thyroid hormones (THs), and more precisely the 3,3',5-triiodo-l-thyronine (T(3)) acetic derivative 3,3',5-triiodothyroacetic acid (TRIAC), have been shown to activate metamorphosis in amphioxus. However, it remains unknown whether TRIAC is endogenously synthesized in amphioxus and more generally whether an active TH metabolism is regulating metamorphosis. Here we show that amphioxus naturally p...

Hemps, a novel epidermal growth factor (EGF)-like protein, is expressed during larval development and early metamorphosis in the ascidian Herdmania curvata and plays a direct role in triggering metamorphosis. In order to identify downstream genes in the Hemps pathway we used a gene expression profiling approach, in which we compared post-larvae undergoing normal metamorphosis with larval metamo...

Abstract Conceptual metaphor theory (CMT) and cultural linguistics (CL), which form the chief theoretical anchor for this study, express role of language, culture cognition in construal expression human experiences. The approaches posit that metaphorical use language by an individual or group is shaped their ideological orientation, knowledge natural social world, worldview. This study investig...

In many marine invertebrates, larval metamorphosis is induced by environmental cues that activate sensory receptors and signalling pathways. Nitric oxide (NO) is a gaseous signalling molecule that regulates metamorphosis in diverse bilaterians. In most cases NO inhibits or represses this process, although it functions as an activator in some species. Here we demonstrate that NO positively regul...
