RESEARCH ARTICLES

Summary:Drosophila immigrans flies acclimated at 7°C (on food) showed an increase in body lipids and starvation resistance but there were no such plastic effects for flies acclimated at 0°C.

Summary: Upon large-scale brain excision in adult newts, the outcome of structural regeneration of the brain cytoarchitecture depends on ways of closing the wound by NSCs residing between brain subregions.

Summary: We found that seahorse reproduction could adapt to higher-temperature conditions, but seahorses might experience massive mortality rates due to high basal metabolic rates and stress damage under chronic thermal stress.

Summary: BCG enhanced the survival of dendritic cells (DCs) and prolonged their lifespan. BCG promoted DC survival by up-regulating Bcl-2 and Bcl-xL. Increased survival of BCG-stimulated DCs was dependent on NF-κB, but was independent of MyD88 signaling.

Summary: Anti-lipopolysaccharide egg yolk antibodies can enhance the phagocytosis of mammalian phagocytes by promoting larger body and more pseudopods, and may be used as new healthcare or pharmaceutical products to prevent and treat infectious diseases.

Summary: Inhibition of apoptosis in mouse embryos reveals rudiments of the lateral line system, a sensory system common to fish and aquatic amphibia, but hypothesized to be completely lost in amniotes.

Summary: Corticosterone in natural and regrown feathers was similar between urban and rural birds. Sex and age related to corticosterone in regrown feathers. Feather corticosterone was not consistent across different moults.

Summary: The gut bacterial microbiome of rainbow trout contains a few core bacterial taxa and has little overlap with its faeces. Bacterial communities can change even 3 h after feeding.

Summary: This present study demonstrates that the response of BMSCs to tension potentiates paracrine osteogenic signaling from co-cultured VECs; this positive feedback loop is initiated by VEGF release.

Summary: This paper considers how fish may have evolved methods to utilize modulation of their bladders to convey additional information.

Summary: We show that flies respond behaviourally to song amplitude structure; this observation suggests it may be a communication signal in Drosophila. We discuss our work in the broader context of other animals using amplitude modulations to communicate.

Summary: We show that bone morphogenetic protein and nodal drive epithelial-mesenchymal transition (EMT) and invasiveness in melanoma cells, induce EMT and a melanoma-like invasive phenotype in melanocytes.

Summary: In this scanning electron microscopy study, we report the physiological findings regarding the structures of the epidermis of planarians, before and after exposure to temperature and pH stressors.

Summary: Using isogenic lines, this study determines some new, unexpected molecular regulation of the glucose metabolism in rainbow trout, which may partly lead to the poor utilization of dietary carbohydrates.

METHODS & TECHNIQUES

Summary: A semi-automatic analytical method for the assessment of the optomotor response was developed. This procedure was animal friendly and enabled the quantitative evaluation of fish optic behavior.

Summary: We developed and tested a simple electronic device allowing continual temperature monitoring of developing embryos that provides a metric for embryonic staging that compensates for fluctuations in ambient temperature.
