Descriptive anatomy of "Iso rhothophilus" (Ogilby), with a phylogenetic analysis of "Iso" and a redefinition of Isonidae (Atheriniformes)

The musculoskeletal anatomy of "Iso rhothophilus" is described. A phylogenetic analysis of the genus, using eleven anatomical dlaracters, indicates that the systematic hierarchy is ("Iso flosmaris" ("I. nesiotes" ("I. rhothophilus" ("I. hawaiiensis", "I. natalensis")))). Isonidae Rosen, 1964 is redefined and, on the basis of twenty characters (autapomorphic within Atheriniformes) shown to be distinct from Notocheiridae Schultz, 1950.19 page(s

Growth effects in oregano plants (Origanum vulgare L.) assessment through inoculation of bacteria isolated from crop fields located on desert soils.

The bacteria can establish beneficial interactions with plants acting as growth promoters and enhance stress tolerance during plant interactions. Likewise, bacteria are able to develop multi-species communities where multiple interactions are possible. In this work, we assessed the physiological effects of three bacteria isolated from an arid environment (Bacillus niacini, B. megaterium, and Moraxella osloensis) applied as single-species or as a consortium, on oregano (Origanum vulgare L.) plants. Moreover, we assessed the quorum-sensing (QS) signaling activity to determine the molecular communication between plant growth-promoting (PGP) bacteria. The plant inoculation with B. megaterium showed a positive effect on morphometric and physiologic parameters. However, no synergistic effects were determined when bacterial consortium were inoculated. Likewise, the QS signaling activation in biofilm assays was determined only for inter-species interaction inside the Bacillus genus, but not activation with either interaction with M. osloensis. These results suggest a neutral or antagonistic interaction for inter-specific bacterial biofilm establishment, as well as for the interaction with oregano plants when bacteria were inoculated in a consortium. In conclusion, we were able to determine that the bacterial interactions are not always positive or synergistic, but also might be neutral or antagonistic.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Head morphology of the ricefish, Oryzias latipes (Teleostei: Beloniformes)

The medaka, Oryzias latipes, is a model organism in experimental biology. Its ontogeny and osteology have been studied frequently, but no detailed description of its cranial anatomy exists. Based on manual dissections, histological slide sections, and 3D-reconstructions, we describe the anatomy of the jaw apparatus of O. latipes, focusing on musculature, connective tissue elements, and the nervous system. The soft tissue anatomy of the head of O. latipes is characterized by several derived characters that seem to be related to the modification of the upper jaw and a reduced mobility of its bones, which is an evolutionary novelty of the Beloniformes. These apomorphies could also be influenced by the small size of O. latipes. The maxilla is medial to the premaxilla. The presence of extensive connective tissue elements severely limits the mobility of both bones against each other and against the neurocranium. The external section of m. adductor mandibulae is partly fused with the internal section, originates from the quadrate, and inserts to the lower jaw. The intermediate head of the internal section is narrow and forms a bend along the ventral margin of the orbit. The intramandibular section is a separate narrow muscle between retroarcticular and dentary. These characters need to be verified in other representatives of Beloniformes to test their contribution to the disputed phylogenetic relationships within this taxon and to improve the understanding of the evolution of beak-like jaws in beloniform fishes

The problem of workforce for the social world of Australian rural nurses: a collective action frame analysis

Aim and background: Globally, nursing workforce shortages are a hot topic for discussion among politicians, academics and clinicians. This paper uses collective action framing to analyse the literature about the problem of workforce for Australian rural nurses. Evaluation: As part of a larger constructivist grounded theory study, we utilize collective action framing to bridge social world mapping and the literature. Data sources included journal databases, newspapers, newsletters and websites. We limited the years searched from 2000 to 2005. This analytical heuristic categorizes text into three main categories: diagnoses of a problem, postulations of solutions and actions to motivate change. Key issues: Having mapped the social world of Australian rural nurses as comprising four groups of collective actors – community, advocates, academics and government – we trace the texts that they have produced with a focus on mentoring as a potential solution to the problem of workforce. Conclusions: Mentoring entered the literature about the problem of workforce for Australian rural nurses because of a combination of political and academic will. These collective groups are now changing how they are framing the problem of workforce to focus instead on the globalization of nursing workforce shortages, which is resulting in diminished support for mentoring activities in clinical practice
