    Notizen: . In vitro excystation of Spironucleus muris cysts, purified by sequential sucrose and Percoll gradients from mouse feces, was studied. Three in vitro excystation procedures, used for Giardia, were assessed to determine the most useful method. Excystation was monitored by light microscopy and subsequently characterized by transmission and scanning electron microscopy. Spironucleus muris excysted routinely at a level greater than 90% when induced in Hanks’ balanced salt solution containing sodium bicarbonate at pH 2.0 and transferred to Tyrodes’ salt solution as an excystation medium. Similarly, high rates of excystation were recorded after induction of S. muris cysts in 0.1 M potassium phosphate buffer (pH 7.0) with sodium bicarbonate and excystation in trypticase-yeast extract-iron medium (TYI medium) or phosphate-buffered saline. A lower rate and percentage of excystation were observed after induction of S. muris cysts in an aqueous hydrochloric acid solution (pH 2.0) followed by excystation in TYI medium. All excystation methods produced extremely active S. muris trophozoites with normal morphology. Nonexcysting S. muris cysts have a wall composed of an outer fibrous and an inner membranous portion. Following induction, numerous vesicles appeared in the peritrophic space. Excystation began by the cyst wall opening at one pole, and the anterior part of the trophozoite protruding from the cyst wall. The trophozoite emerged progressively from the cyst wall and the empty cyst wall appeared to collapse. Excysted trophozoites exhibited normal morphological features of S. muris trophozoites isolated from the mouse intestine.

    Beschreibung: We present a new technique for the statistical evaluation of the Tully–Fisher relation (TFR) using spectral line stacking. This technique has the potential to extend TFR observations to lower masses and higher redshifts than possible through a galaxy-by-galaxy analysis. It further avoids the need for individual galaxy inclination measurements. To quantify the properties of stacked H i emission lines, we consider a simplistic model of galactic discs with analytically expressible line profiles. Using this model, we compare the widths of stacked profiles with those of individual galaxies. We then follow the same procedure using more realistic mock galaxies drawn from the S 3 -SAX model (a derivative of the Millennium simulation). Remarkably, when stacking the apparent H i lines of galaxies with similar absolute magnitude and random inclinations, the width of the stack is very similar to the width of the deprojected (= corrected for inclination) and dedispersed (= after removal of velocity dispersion) input lines. Therefore, the ratio between the widths of the stack and the deprojected/dedispersed input lines is approximately constant – about 0.93 – with very little dependence on the gas dispersion, galaxy mass, galaxy morphology and shape of the rotation curve. Finally, we apply our technique to construct a stacked TFR using H i Parkes All-Sky Survey (HIPASS) data which already has a well-defined TFR based on individual detections. We obtain a B -band TFR with a slope of –8.5 ± 0.4 and a K -band relation with a slope of –11.7 ± 0.6 for the HIPASS data set which is consistent with the existing results.

    Beschreibung: Omic BON is a thematic Biodiversity Observation Network under the Group on Earth Observations Biodiversity Observation Network (GEO BON), focused on coordinating the observation of biomolecules in organisms and the environment. Our founding partners include representatives from national, regional, and global observing systems; standards organizations; and data and sample management infrastructures. By coordinating observing strategies, methods, and data flows, Omic BON will facilitate the co-creation of a global omics meta-observatory to generate actionable knowledge. Here, we present key elements of Omic BON's founding charter and first activities.

    Beschreibung: "An Equal Burden forms the first scholarly study of the Army Medical Services in the First World War to focus on the roles and experiences of the men of the ranks of the Royal Army Medical Corps (RAMC). These men, through their work as stretcher bearers and orderlies, provided a range of labour, both physical and emotional, in aid of the sick and wounded. They were not professional medical caregivers, yet were called upon to provide medical care, however rudimentary; they served in uniform, under military discipline, yet were forbidden, as non-combatants, from carrying weapons. Their service as men in wartime, was thus unique. Structured both chronologically and thematically, this study examines both the work that RAMC rankers undertook and its importance to the running of the chain of medical evacuation. It additionally explores the gendered status of these men within the medical, military and cultural hierarchies of a society engaged in total war, locating their service within the context of that of doctors, female nurses and combatant servicemen. Through close readings of official documents, personal papers, and cultural representations, both verbal and visual, it argues that the ranks of the RAMC formed a space in which non-commissioned servicemen, through their many roles, defined and redefined medical caregiving as men’s work in wartime."
