In order to examine the Earth’s magnetic intensity and inclination during homing migration of chum salmon (Oncorhynchus keta) and to present tracking data consistent with the geomagnetic imprinting hypothesis that salmon migrate homeward using the Earth’s magnetic intensity or inclination, archival tagging operations were carried out in the Bering Sea in 2012 and 2013. DST magnetic tags were at...

A number of landmark-based navigation algorithms have been studied using feature extraction over the visual information. In this paper, we apply the distance information of the surrounding environment in a landmark navigation model. We mount a depth sensor on a mobile robot, in order to obtain omnidirectional distance information. The surrounding environment is represented as a circular form of...

Homing by the nocturnal Namib Desert spider Leucorchestris arenicola (Araneae: Sparassidae) is comparable to homing in diurnal bees, wasps and ants in terms of path length and layout. The spiders' homing is based on vision but their basic navigational strategy is unclear. Diurnal homing insects use memorised views of their home in snapshot matching strategies. The insects learn the visual scene...

The skin is an important barrier organ and frequent target of autoimmunity and allergy. In this study, we found innate-like B cells that expressed the anti-inflammatory cytokine IL-10 in the skin of humans and mice. Unexpectedly, innate-like B1 and conventional B2 cells showed differential homing capacities with peritoneal B1 cells preferentially migrating into the inflamed skin of mice. Import...

Amongst the activities of the European Commission IST research project MIND [1] is extensive consideration of the multi-homing issues in IP access networks. Analysis of the various multi-homing scenarios reveals diverse aspects of multi-homing relevant to both the operations of the access network as well as the hosts connected to it. The originality of the work presented in this paper is arisin...

Inflammation is a hallmark of cancer. Activated immune cells are intrinsically capable of homing to inflammatory sites. Using three inflammatory-driven disease mouse models, we show that grapefruit-derived nanovectors (GNV) coated with inflammatory-related receptor enriched membranes of activated leukocytes (IGNVs) are enhanced for homing to inflammatory tumor tissues. Blocking LFA-1 or CXCR1 a...

AIMS Mononuclear cells (MNCs) from patients with hereditary haemorrhagic telangiectasia type 1 (HHT1), a genetic disorder caused by mutations in endoglin, show a reduced ability to home to infarcted mouse myocardium. Stromal cell-derived factor-1alpha (SDF-1alpha) and the chemokine receptor CXCR4 are crucial for homing and negatively influenced by CD26. The aim of this study was to gain insight...

OMING OF hematopoietic progenitors can be defined H as the set of molecular interactions that mediates the recognition of hematopoietic stem cells and other progenitor cells by marrow stroma after the progenitor cells are intravenously introduced into a recipient. Through this recognition mechanism, circulating progenitor cells bind selectively to the marrow stroma and begin the process of prol...

The BDNF-induced increase (left) in synapses (red) on a neuron (green) is lost if í µí»ƒ-catenin and cadherin are locked together (right). S tem cells become much more effi cient at muscle repair if they fi rst get a boost of cytokines and migratory adhesion molecules, report Galvez et al. (page 231). The improved repair stems from better homing abilities. Skeletal muscle can be repaired by a c...

The elderly are characterized by mucosal immunosenescence and high rates of morbidity and mortality associated with infectious diseases of the intestinal tract. Little is known about how the differentiation of immunoglobulin A (IgA) plasma cells in Peyer's patches (PPs) and their subsequent homing to the small intestinal lamina propria (LP) is affected by aging. Quantitative immunohistochemical...
