description: Hydrothermal vent-associated microbial mats play an important role in food webs and mineralization processes but their composition and diversity are poorly understood, especially in shallow hydrothermal systems where both light and chemical energy are available. This study compared the bacterial communities of three microbial mat samples collected from Volcano 1 on the Tonga-Kermadec Arc using a PCR-based approach. Small subunit rRNA gene clone libraries were created from two samples from photic and aphotic depths and found to be highly similar in composition and highly diverse relative to other deep and shallow vent microbial mats. The role of fluctuating hydrothermal discharge in maintaining this high level of diversity is discussed. Both samples were dominated by Gammaproteobacteria with Epsilonproteobacteria as the second most abundant group. A third sample from a previously characterized Volcano 1 Fe-oxide deposit was used for comparison. The photic and aphotic samples were phylogenetically similar while there was limited similarity between the aphotic and Fe-oxide samples which are both from aphotic depths. This suggests a lesser (if any) role for the presence or absence of light in determining community composition in comparison with the role of hydrothermal conditions.

description: An enantioselective total synthesis of (−)-mucocin has been completed. A combination of asymmetric glycolate aldol additions and ring closing metathesis reactions were exploited to construct the C18−C34 and C7−C17 fragments. A selective cross-metathesis reaction was employed as the key step to couple two complex fragments.

description: INTRODUZIONE Gli infermieri in area critica necessitano di capacità nel saper integrare conoscenze teoriche avanzate e abilità pratiche per soddisfare le esigenze di assistenza dei pazienti in condizioni critiche. OBIETTIVO Lo studio presentato si propone di ricercare i percorsi formativi post-base per l’infermiere di area critica, le tecniche che maggiormente conducono a un miglioramento delle loro conoscenze e competenze. MATERIALI E METODI Gli autori hanno condotto una revisione sistematica della durata di sette mesi. La revisione è stata condotta su tre banche dati. È stata disposta una stringa di ricerca sulla base del PICO selezionato. È stato redatto un diagramma di flusso PRISMA. Si sono stabiliti i criteri di inclusione ed esclusione. Sono stati utilizzati molteplici strumenti di valutazione della qualità degli studi. RISULTATI La stringa di ricerca ha permesso di ottenere 506 articoli. Dopo la rimozione dei duplicati, la selezione con criteri di inclusione ed esclusione, la valutazione qualitativa, la revisione ha incluso 41 studi. DISCUSSIONE E CONCLUSIONI L’indagine ha affermato l’importanza dell’aggiornamento continuo delle conoscenze e competenze del personale che eroga la propria assistenza in contesti di elevata complessità assistenziale. Emerge una scarsa uniformità nella definizione di percorsi formativi standardizzati. La ricerca australiana ha permesso di sviluppare uno strumento di valutazione del livello di pratica atteso dopo un programma di formazione. La simulazione viene individuata come migliore strategia di insegnamento per i corsi post-laurea in area critica.

description: BACKGROUND: To validate a short cognitive test: the Test Your Memory for Mild Cognitive Impairment (TYM-MCI) in the diagnosis of patients with amnestic mild cognitive impairment or mild Alzheimer’s disease (aMCI/AD). METHODS: Two hundred and two patients with mild memory problems were recruited. All had ‘passed’ the Mini-Mental State Examination (MMSE). Patients completed the TYM-MCI, the Test Your Memory test (TYM), MMSE and revised Addenbrooke’s Cognitive Examination (ACE-R), had a neurological examination, clinical diagnostics and multidisciplinary team review. RESULTS: As a single test, the TYM-MCI performed as well as the ACE-R in the distinction of patients with aMCI/AD from patients with subjective memory impairment with a sensitivity of 0.79 and specificity of 0.91. Used in combination with the ACE-R, it provided additional value and identified almost all cases of aMCI/AD. The TYM-MCI correctly classified most patients who had equivocal ACE-R scores. Integrated discriminant improvement analysis showed that the TYM-MCI added value to the conventional memory assessment. Patients initially diagnosed as unknown or with subjective memory impairment who were later rediagnosed with aMCI/AD scored poorly on their original TYM-MCI. CONCLUSION: The TYM-MCI is a powerful short cognitive test that examines verbal and visual recall and is a valuable addition to the assessment of patients with aMCI/AD. It is simple and cheap to administer and requires minimal staff time and training.

description: A small-sized clausidiid copepod was found associated with the commercially important bivalve, Ruditapes philippinarum, from a Korean coastal lagoon. Since it resembles morphologically a European form known as Hersiliodes latericius, it is attributed to a new species, H. exiguus n. sp., of the same genus. The uneasy distinction between the genera Hersiliodes and the very similar Hemicyclops is discussed.

description: Composition and structure of mytilid and alvinocaridid shrimp assemblages were studied at three hydrothermal fields on the Mid-Atlantic Ridge: Rainbow, Broken Spur and Snake Pit. Strong differences in taxonomic richness and composition of predominant taxa were revealed between mytilid and shrimp assemblages. Mytilid assemblages were more diverse, and exhibited greater evenness than shrimp assemblages at Snake Pit vent field. These differences confirm the
 existence in the investigated area of at least two types of hydrothermal faunal assemblages, which have previously been identified visually.

description: Saari's homographic conjecture claims that, in the N-body problem under the homogeneous potential, $U=α^{-1}\sum m_i m_j/r_{ij}^α$ for $α\ne 0$, a motion having constant configurational measure $μ=I^{α/2}U$ is homographic, where $I$ represents the moment of inertia defined by $I=\sum m_i m_j r_{ij}^2/\sum m_k$, $m_i$ the mass, and $r_{ij}$ the distance between particles. We prove this conjecture for general masses $m_k>0$ in the planar three-body problem under Newton potential ($α=1$) and a strong force potential ($α=2$).

description: The whale-fall mussel Adipicola pacifica was analysed to determine its reproductive strategy. The sex ratio and size at maturity were examined based on histological analyses. The total number of males (n = 110) was much larger than that of females (n = 19) under aquarium conditions, although the numbers of males (n = 45) and females (n = 36) were nearly identical in their natural habitat. Hermaphroditic specimens were observed both in aquaria and in situ. The mean shell lengths of males, females and hermaphrodites were 12.68 mm (SD = 3.20, n = 155), 15.12 mm (SD = 2.82, n = 55) and 13.71 mm (SD = 2.46, n = 30), respectively, which suggested protandric hermaphroditism. The smallest individual (4.57 mm in shell length) examined in this study was a mature male, which was 21% of the size of the largest specimen of this species collected from the natural habitat in this study. This size was similar to that of mussels collected from other
 deep-sea reducing environments but much smaller than that in intertidal environments. This reproductive strategy might allow A. pacifica to inhabit ephemeral and insular environments such as whale falls.

description: Public health practitioners require measures to evaluate how vulnerable populations are to diseases, especially for zoonoses (i.e. diseases transmitted from animals to humans) given their pandemic potential. These measures would be valuable to support strategic and operational decision making and allocation of resources. Although vulnerability is well defined for natural hazards, for public health threats the concept remains undetermined. Here, we develop new methodologies to: (i) quantify the impact of zoonotic diseases and the capacity of countries to cope with these diseases, and (ii) combine these two measures (impact and capacity) into one overall vulnerability indicator. The adaptive capacity is calculated from estimations of disease mortality, although the method can be adapted for diseases with no or low mortality but high morbidity. As an example, we focused on the vulnerability of Nigeria and Sierra Leone to Lassa Fever and Ebola. We develop a simple analytical form that can be used to estimate vulnerability scores for different spatial units of interest, e.g. countries or regions. We show how some populations can be highly vulnerable despite low impact threats. We finally outline future research to more comprehensively inform vulnerability with the incorporation of relevant factors depicting local heterogeneities (e.g. bio-physical and socio-economic factors).This article is part of the theme issue ‘Detection, forecasting and control of infectious disease epidemics: modelling outbreaks in humans, animals and plants Part 2’.

description: Given that relatively simple electrophoretic methods have repeatedly proven their usefulness in sorting out difficult species complexes, it seemed a promising approach to apply them to various local populations of E. viridis in order to test whether this species name is in fact being used for more than a single species. Specimens were collected from geographically separated local populations in the Channel region (Saint-Efflam, Granville) and the North Sea (Newcastle, Norderney, Helgoland, Helsingør and Tjärnö). Particular enzymes and general protein patterns of individual animals were compared by means of isoelectric focusing (IEF), and the animals were examined for morphological differences. Distinct differences between the IEF band patterns of specimens from the western and eastern sites were indeed observed, and these were found to be correlated with differences in the morphology and size of the dorsal cirri and the size of the proboscideal papillae. Therefore, it became necessary to subdivide the material into two species, E. viridis for that found in Sweden, Denmark and Germany and E. clavigera for that from France and England.

Investigation of the temporal development of Tau pathology in TAU58/2 transgenic mice

Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Alzheimer’s disease (AD) is a progressive neurodegenerative disease, which is a major public health burden in the world. Despite recent progress has been made in understanding the pathology of AD, the exact causes of AD are still unclear. Two of the hallmark pathologies of AD are the formation of β-amyloid plaques and neurofibrillary tangles (NFTs). NFTs are composed of hyperphosphorylated Tau protein which aggregates and forms insoluble Tau. Several transgenic mouse models for AD have been developed to identify the underlying molecular mechanisms by demonstrating tauopathy such as TAU58/2, a P301S mutant Tau transgenic mouse line. Current study has investigated the expression profile of Tau regarding different phosphorylation sites, and isoforms in TAU58/2 mouse model in hippocampus during different stages of disease progression by Western blot, and in comparison with their wild type littermates. Also, abnormal Tau distribution, morphology, and its correlation with neuronal loss as well as neuroinflammation in TAU58/2 mouse model has been studied by immunohistochemistry. Data provided by this MRes project will define the time points for future experiments that will seek to downregulate these proteins. Tau phosphorylation at Ser202/Thr205 and Thr231 sites as well as total Tau levels were increased in hippocampus both in three and twelve months old, whereas insoluble Tau formation only occurred in 12 months and at Ser202/Thr205 phosphorylation site. Results obtained from Western blot were confirmed by IHC; in addition, it uncovered the distribution and morphology of Phospho-Tau, as well as Astrogliosis. These results provide important insights into Tauopathy in TAU58/2 mouse model at two timepoints. Given the fact that reported changes begin as soon as 3 months of age, additional studies to assess neuronal loss and neuroinflammation are needed to gain a comprehensive understanding of the best timepoint to apply nanoparticle-based therapies in the future.

description: The giant colonial marine ciliate Zoothamnium niveum is a symbiont-harboring protozoan reported from sunken plants in the red Sea, Gulf of Mexico, Caribbean Sea, and Mediterranean Sea. We discovered the ciliate on the surface of a whale vertebra deployed at a depth of 5 m in Tokyo Bay, Japan. Molecular phylogenetic analyses confirmed that the ciliate was identical to Z. niveum reported off Florida, and that the ectosymbiont was also identical to the thioautotrophic ectosymbionts of Z. niveum reported from the Caribbean Sea and Mediterranean Sea. This is the first report of Z. niveum from the Pacific and also the first appearance on any animal carcass. These findings indicate that this symbiont-harboring ciliate is cosmopolitan and that sunken whale carcasses provide a suitable reducing environment for chemosymbiotic organisms not only in deep-sea but also in shallow-water environments although the host taxa vary among sites.

Mixed photosynthetic-chemosynthetic diets in vent obligate macroinvertebrates at shallow hydrothermal vents on Volcano 1, South Tonga Arc - evidence from stable isotope and fatty acid analyses

description: Several submerged, hydrothermally active arc volcanoes in the southern and western Pacific Ocean rise to photic zone depths. These settings provide an opportunity to investigate the trophic ecology of vent-obligate species in a non-coastal, shallow-water context where both chemosynthetic and photosynthetic carbon sources are present. We report here on a stable isotope and lipid biomarker study of food web relationships in hydrothermal vent communities on Volcano 1, located along the southern Tonga Arc, in the southwestern Pacific. Active venting and vent communities were found at two locations in the photic zone (100 m depth) and at a 200 m deep site. All three locations were colonized by bathymodiolan mussels. Hydrothermal vent limpets (Shinkailepas sp. and Lepetodrilus sp.) were also sampled at these sites together with the vent crab Xenograpsus ngatama. Our collections of Bathymodiolus sp., Shinkailepas sp., and Lepetodrilus sp. at the two
 100 m deep sites represent the shallowest known occurrences for these vent-endemic genera. Filamentous green algae were found in limpet guts and growing on rock and other surfaces at the photic zone sites. Stable isotope and lipid results indicated that crab and limpet species at the photic zone sites had a mixed diet of photosynthetic and chemosynthetic food sources, while specimens from 200 m relied on chemosynthetic material only. Even the symbiont-containing mussels from
 the shallower sites had stronger (albeit minor) photosynthetic signatures than did mussels from 200 m. The oceanic location of these photic zone vents may be a factor in explaining the presence of vent-obligate species, since coastal vent systems typically lack vent endemic metazoans. We predict that other studies of photic zone vents in volcanic arc settings will find communities of vent, and possibly non-vent, species exploiting mixed photosynthetic-chemosynthetic diets.

description: The pumping rates (PR, ml.min- I) of Tapes decussatus and Ruditapes philippinarum are measured with a new apparatus using the "constant level tank principle" of Galstoff. When the dry soft mass (DM, g) ranges between 0.15 g and 1 g, the values are given by PR = 122·DM -77'DM2 (R2 = 0.96) and PR = 124·DM -87 'DM2 (R2 = 0.91) respectively. The maximal fluctuation of the pumping rate is 10 % when the temperature increases by 10°C in 150 minutes. By contrast, when the particulate concentration increases from 20 mg.l-1 to 500 mg.l-1 in 200 minutes, the pumping rate of R: philippinarum is reduced by 90% as soon as the concentration reaches 350 mg'l- I while the maximal reduction of the pumping rate of T. decussatus at 500 mg.l-1 is less than 50%. We go on the assumption that R. philippinarum controIS'the ingested volume by reducing the pumping rate, while T. decussatus uses the production of pseudofaeces.

Adventitious Ag+ (typically from LAuCl activation) can therefore intercept key organogold intermediates and effect the catalysis even when it does not effect the reaction in Au free control experiments.

description: The centre of our Galaxy is one of the most studied and yet enigmatic places in the Universe. At a distance of about 8 kpc from our Sun, the Galactic centre (GC) is the ideal environment to study the extreme processes that take place in the vicinity of a supermassive black hole (SMBH). Despite the hostile environment, several tens of early-type stars populate the central parsec of our Galaxy. A fraction of them lie in a thin ring with mild eccentricity and inner radius ~0.04 pc, while the S-stars, i.e. the ~30 stars closest to the SMBH (<0.04 pc), have randomly oriented and highly eccentric orbits. The formation of such early-type stars has been a puzzle for a long time: molecular clouds should be tidally disrupted by the SMBH before they can fragment into stars. We review the main scenarios proposed to explain the formation and the dynamical evolution of the early-type stars in the GC. In particular, we discuss the most popular in situ scenarios (accretion disc fragmentation and molecular cloud disruption) and migration scenarios (star cluster inspiral and Hills mechanism). We focus on the most pressing challenges that must be faced to shed light on the process of star formation in the vicinity of a SMBH.

description: Cationic gold(I) phosphite catalysts activate allenes for epoxide cascade reactions. The system is tolerant of numerous functional groups (sulfones, esters, ethers, sulfonamides) and proceeds at room temperature in dichloromethane. The cyclization pathway is sensitive to the substitution pattern of the epoxide, and the backbone structure of the A-ring. It is capable of producing medium-ring ethers, fused 6-5 bicyclic, and linked pyran-furan structures. The resulting cycloisomers are reminiscent of structures found in numerous polyether natural products.

Publisher: name: Station Biologique de Roscoff (SBR)
Year: 1995

description: Halechiniscus chafarinensis n. sp., from Chafarinas Islands (SE Alboran Sea, N. Africa), shares plesiomorphic characteristics with other species of Halechiniscus (H. tuleari, H. paratuleari and H. macrocephalus), namely the division of the head in two lobes, the presence of large cirrophori supporting cephalic cirri, and evident lateral processes. The former character may be also an evidence of relationship between Halechiniscidae and Stygarctidae.

description: A highly convergent, enantioselective total synthesis of the potent antitumor agent apoptolidin A, has been completed. The key transformations include highly selective glycosylations to attach the C27 disaccharide and the C9 6′-deoxy-l-glucose, a cross metathesis to incorporate the C1-C10 trienoate unit, and a Yamaguchi macrolactonization to complete the macrocycle. Twelve stereocenters in the polypropionate segments and sugar units were established through diastereoselective chlorotitanium enolate aldol reactions.

Comprehensive abundance analysis of red giants in the open clusters NGC 1342, 1662, 1912, 2354 and 2447

description: We have observed high-dispersion echelle spectra of red giant members in the five open clusters NGC 1342, NGC 1662, NGC 1912, NGC 2354 and NGC 2447 and determined their radial velocities and chemical compositions. These are the first chemical abundance measurements for all but NGC 2447. We combined our clusters from this and previous papers with a sample drawn from the literature for which we remeasured the chemical abundances to establish a common abundance scale. With this homogeneous sample of open clusters, we study the relative elemental abundances of stars in open clusters in comparison with field stars as a function of age and metallicity. We find a range of mild enrichment of heavy (Ba-Eu) elements in young open cluster giants over field stars of the same metallicity. Our analysis succinct that the youngest stellar generations in cluster might be under-represented by the solar neighbourhood field stars.

On the universal mod $p$ supersingular quotients for $\mathrm {GL}_2(F)$ over $\overline{\mathbb F}_p$ for a general $F/\mathbb{Q}_p$

description: Let $F/\mathbb{Q}_p$ be a finite extension. We explore the universal supersingular mod $p$ representations of $\mathrm{GL}_2(F)$ through computing a basis of their invariant space under the pro-$p$ Iwahori subgroup. This generalizes works of Breuil and Schein from $\mathbb{Q}_p$ and the totally ramified cases to the arbitrary one. Using these results we then construct for an unramified $F/\mathbb{Q}_p$ a quotient of the universal supersingular module which has as quotients all the supersingular representations of $\mathrm{GL}_2(F)$ with a $\mathrm{GL}_2(\mathcal{O}_F)$-socle that is expected to appear in the mod $p$ local Langlands correspondence. A construction for the case of an extension of $\mathbb{Q}_p$ with inertia degree 2 and suitable ramification index is also presented.
description: 30 pages, comments welcome. Revised version: bad alignment of equations, typos and some layout issues fixed. Conclusion 1.3 about endomorhpisms of the universal supersingular quotients added. Proofs in Sections 3.2 and 3.3 made clearer. Main results unchanged

description: A total synthesis of brevetoxin A is reported. Two tetracyclic coupling partners, prepared from previously reported advanced fragments, were effectively united via a Horner—Wittig olefination. The resulting octacycle was progressed to substrates that were explored for reductive etherification, the success of which led to a penultimate tetraol intermediate. The tetraol was converted to the natural product through an expeditious selective oxidative process, followed by methylenation.

description: Vector Fitting (VF) is a popular method of constructing rational approximants that provides a least squares fit to frequency response measurements. In an earlier work, we provided an analysis of VF for scalar-valued rational functions and established a connection with optimal $H_2$ approximation. We build on this work and extend the previous framework to include the construction of effective rational approximations to matrix-valued functions, a problem which presents significant challenges that do not appear in the scalar case. Transfer functions associated with multi-input/multi-output (MIMO) dynamical systems typify the class of functions that we consider here. Others have also considered extensions of VF to matrix-valued functions and related numerical implementations are readily available. However to our knowledge, a detailed analysis of numerical issues that arise does not yet exist. We offer such an analysis including critical implementation details here. One important issue that arises for VF on matrix-valued functions that has remained largely unaddressed is the control of the McMillan degree of the resulting rational approximant; the McMillan degree can grow very high in the case of large input/output dimensions. We introduce two new mechanisms for controlling the McMillan degree of the final approximant, one based on alternating least-squares minimization and one based on ancillary system-theoretic reduction methods. Motivated in part by our earlier work on the scalar VF problem as well as by recent innovations for computing optimal $H_2$ approximation, we establish a connection with optimal $H_2$ approximation, and are able to improve significantly the fidelity of VF through numerical quadrature, with virtually no increase in cost or complexity. We provide several numerical examples to support the theoretical discussion and proposed algorithms.

description: There have been very few studies of temporal processes at chemosynthetic ecosystems, even at relatively more accessible shallow water sites. Here we report the development and deployment of a simple cabled video observatory at ≈ 30 m water depth in Gullmarsfjorden, Sweden. The camera provides a live video feed to the internet of faunal activity in the experiments, which to date have included 5 separate whale-fall deployments. Our data suggest that the time to decomposition of small cetacean carcasses at shelf-depth settings is considerably slower than at deep-sea sites. We have also provided a new methodology for the deployment of low-cost live video observatories at up to 30 m water depth, which can be used both for research and outreach activities.

description: Application of the nuclear track emulsion technique (NTE) in radioactivity and nuclear fission studies is discussed. It is suggested to use a HSP-1000 automated microscope for searching for a collinear cluster tri-partition of heavy nuclei implanted in NTE. Calibrations of $α$-particles and ion ranges in a novel NTE are carried out. Surface exposures of NTE samples to a ${}^{252}$Cf source started. Planar events containing fragments and long-range $α$-particles as well as fragment triples only are studied. NTE samples are calibrated by ions Kr and Xe of energy of 1.2 and 3 A MeV.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Progress toward a highly convergent, asymmetric synthesis of brevenal is reported. Construction of the AB-ring and E-ring cyclic ether fragments was achieved through asymmetric alkylation/ring-closing metathesis strategies. A Horner-Wadsworth-Emmons olefination was used in a key bond-forming step to couple the advanced cyclic fragments and enable rapid access to the AB-E ring system.
