We succeeded in visualization of the primordial germ cells (PGCs) in a living Xenopus embryo. The mRNA of the reporter Venus protein, fused to the 3' untranslated region (UTR) of DEADSouth, which is a component of the germ plasm in Xenopus eggs, was microinjected into the vegetal pole of fertilized eggs and then the cells with Venus fluorescence were(More)
The Purkinje fibers are located in the ventricular walls of the heart, just beneath the endocardium and conduct excitation from the right and left bundle branches to the ventricular myocardium. Recently, anatomists succeeded in photographing the Purkinje fibers of a sheep, which clearly showed the mesh structure of the Purkinje fibers. In this study, we(More)
DEADSouth mRNA encoding the RNA helicase DDX25 is a component of the germ plasm in Xenopus laevis. We investigated the mechanisms underlying its specific mRNA expression in primordial germ cells (PGCs). Based on our previous findings of several microRNA miR-427 recognition elements (MREs) in the 3' untranslated region of the mRNA, we first examined whether(More)
DEADSouth mRNA is a component of germ plasm in Xenopus laevis and encodes a DDX25 DEAD-box RNA helicase. To determine the intracellular localization of DEADSouth protein, we injected mRNA encoding DEADSouth tagged with mCherry fluorescent protein into fertilized eggs from transgenic Xenopus expressing EGFP fused with a mitochondrial targeting signal. The(More)
In ubiquitous networks, Mobile Nodes (MNs) may often suffer from performance degradation due to the following two reasons: (1) reduction of signal strength by an MN's movement and intervening objects , and (2) radio interference with other WLANs. Therefore, quick and reliable detection of the deterioration of a wireless link condition is essential for(More)
UNLABELLED Myofascial pain syndrome (MPS) is an important clinical condition characterized by chronic muscle pain and a myofascial trigger point (MTrP) located in a taut band (TB). However, its pathogenic mechanism is still unclear. We developed an animal model relevant to conditions of MPS, and analyzed the mechanism of the muscle pain in this model. We(More)
PURPOSE To establish a rat model of neurotrophic keratopathy and to examine the effects of the combination of substance P (SP) and insulin-like growth factor (IGF)-1 on corneal epithelial barrier function and wound healing in this model. METHODS Corneal denervation was achieved by thermocoagulation of the ophthalmic branch of the trigeminal nerve. A(More)
Purkinje fibers in mammalian hearts are known to comprise the following three groups depending on their structure: group I found commonly in ungulates, group II in humans, monkeys and dogs, and group III in rodents. The aim of the present study was to document precisely the cytoarchitecture of a network of Purkinje fibers in different species by light and(More)
