TL;DR: The results suggest that the ESR has a role in protecting the embryo at the very early stages of seed development, whilst contributes to the general defence mechanism of the kernel at later developmental stages.
Abstract: A Zea mays cDNA clone, ZmESR-6, was isolated as a gene specifically expressed at the basal region of immature kernels. ZmESR-6 cDNA encoded for a small (11.1 kDa) protein homologous to plant defensins. As for other defensins, the protein contained an N-terminal signal peptide signature and a C-terminal acidic peptide, the mature peptide has a molecular mass of 5.5 kDa. ZmESR-6 was highly expressed in developing kernels but the transcript could not be detected in any other maize tissue. The recombinant ZmESR-6 protein, purified from E. coli, showed strong in vitro inhibitory activity against bacterial and fungal plant pathogens, suggesting a role for ZmESR-6 in plant defence. The distribution of the transcripts was restricted to the embryo surrounding region (ESR) of the kernel. Immunolocalisation experiments revealed, however, that at the grain filling phase ZmESR-6 was accumulated in the placentochalaza-cells, rather than in the ESR cells that produce it. Our results suggest that the ESR has a role in protecting the embryo at the very early stages of seed development, whilst contributes to the general defence mechanism of the kernel at later developmental stages.

TL;DR: A novel infectious agent is proposed, mineral forming nanobacteria (NB), to be active nidi that attach to, invade and damage the urinary epithelium of collecting ducts and papilla forming the calcium phosphate center(s) found in most kidney stones.
Abstract: Kidney stone formation is a multifactorial disease in which the defence mechanisms and risk factors are imbalanced in favour of stone formation. We have proposed a novel infectious agent, mineral forming nanobacteria (NB), to be active nidi that attach to, invade and damage the urinary epithelium of collecting ducts and papilla forming the calcium phosphate center(s) found in most kidney stones. Stone formation may proceed in urine supersaturated with calcium phosphate, calcium oxalate and uric acid/urate under the influence of crystallization promoters and inhibitors. Our hypothesis underlines the role of active nidi: even supersaturated urine requires nidi for crystallization to appear.

TL;DR: In this paper, the authors present a conceptual model in which feedbacks between biotic and geomorphic processes, landslides, and ecosystem attributes are hypothesized to drive the dynamics of mountain ecosystems at multiple scales.
Abstract: Landsliding is a complex process that modifies mountainscapes worldwide. Its severe and sometimes long-lasting negative effects contrast with the less-documented positive effects on ecosystems, raising numerous questions about the dual role of landsliding, the feedbacks between biotic and geomorphic processes, and, ultimately, the ecological and evolutionary responses of organisms. We present a conceptual model in which feedbacks between biotic and geomorphic processes, landslides, and ecosystem attributes are hypothesized to drive the dynamics of mountain ecosystems at multiple scales. This model is used to integrate and synthesize a rich, but fragmented, body of literature generated in different disciplines, and to highlight the need for profitable collaborations between biologists and geoscientists. Such efforts should help identify attributes that contribute to the resilience of mountain ecosystems, and also should help in conservation, restoration, and hazard assessment. Given the sensitivity of mountains to land-use and global climate change, these endeavors are both relevant and timely.
