Synthesis and Characterization of Five New Tetrakis(N-phenylacetamidato) Dirhodium(II) Amine Complexes and One Molybdenum Cofactor Described Crystallographically

Six new crystal structures were determined using a Rigaku Mercurcy 375/MCCD(XtaLab mini) diffractometer. The structure of a molybdenum cofactor was solved resulting in an R1 (R1 = Σ ||Fo| - |Fc|| / Σ |Fo|) of 3.61% despite the presence of a disordered DMSO molecule. New Tetrakis(N-phenylacetamidato) Dirhodium(II) complexes were synthesized and characterized. Two 2,2-cis-[Rh2(NPhCOCH3)4]•(C3H4N2)x where x= 1 or 2 were successfully crystallized and solved with R1 values below 5%. Additional studies were conducted via NMR to observe formation of both products. Three potential catalysts were synthesized starting with 3,1-[Rh2(NPhCOCH3)4]. The resulting compounds were a mono adduct 3,1-[Rh2(NPhCOCH3)4]•(C3H4N2), and two dimer of dimers complexes with amine bridges 3,1-[Rh2(NPhCOCH3)4]2•(C8H6N2) and 3,1-[Rh2(NPhCOCH3)4]2•(C10H8N2). All three complexes were crystallized and solved with R1 values less than 10%. Additional NMR studies were conducted to elucidate solid and solution phase structures and to determine the possibility of additional amine bonds forming

The Application of Archival Concepts to a Data-Intensive Environment: Working with Scientists to Understand Data Management and Preservation Needs

The collection, organization, and long-term preservation of resources are the raison d’être of archives and archivists. The archival community, however, has largely neglected science data, assuming they were outside the bounds of their professional concerns. Scientists, on the other hand, increasingly recognize that they lack the skills and expertise needed to meet the demands being placed on them with regard to data curation and are seeking the help of “data archivists” and “data curators.” This represents a significant opportunity for archivists and archival scholars but one that can only be realized if they better understand the scientific context.National Science Foundation under Grant No. 0724300Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/86738/1/Akmonetal2011.pd

An associated cranium and lower jaw from the Cloverly Formation (?middle–late Albian, between 104 and 109 million years old) of southern Montana is designated as the holotype for Aquilops americanus gen. et sp. nov. Aquilops americanus is distinguished by several autapomorphies, including a strongly hooked rostral bone with a midline boss and an elongate and sharply pointed antorbital fossa. The skull in the only known specimen is comparatively small, measuring 84 mm between the tips of the rostral and jugal. The taxon is interpreted as a basal neoceratopsian closely related to Early Cretaceous Asian taxa, such as Liaoceratops and Auroraceratops. Biogeographically, A. americanus probably originated via a dispersal from Asia into North America; the exact route of this dispersal is ambiguous, although a Beringian rather than European route seems more likely in light of the absence of ceratopsians in the Early Cretaceous of Europe. Other amniote clades show similar biogeographic patterns, supporting an intercontinental migratory event between Asia and North America during the late Early Cretaceous. The temporal and geographic distribution of Upper Cretaceous neoceratopsians (leptoceratopsids and ceratopsoids) suggests at least intermittent connections between North America and Asia through the early Late Cretaceous, likely followed by an interval of isolation and finally reconnection during the latest Cretaceous.Funding was received from the National Science Foundation (DEB 9401094, 9870173, http://www.nsf.gov); National Geographic Society (5918-97, http://www.nationalgeographic.com/); and American Chemical Society (PRF #38572-AC8, http://www.acs.org).

Cost-effectiveness of empagliflozin versus canagliflozin, dapagliflozin, or standard of care in patients with type 2 diabetes and established cardiovascular disease

Introduction Empagliflozin, a sodium-glucose co-transporter-2 (SGLT-2) inhibitor, is approved in the USA to reduce risk of cardiovascular (CV) death in adults with type 2 diabetes mellitus (T2DM) and established CV disease, based on EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) trial results. Empagliflozin reduced major adverse CV event (MACE) by 14%, CV death by 38%, and hospitalization for heart failure (HHF) by 35% vs placebo, each on top of standard of care (SoC). SGLT-2 inhibitors canagliflozin and dapagliflozin have also been compared with placebo, all on top of SoC, in CV outcome trials. In the CANVAS (Canagliflozin Cardiovascular Assessment Study) Program, canagliflozin reduced MACE by 14% and HHF by 33%. Dapagliflozin reduced HHF by 27% in the DECLARE-TIMI 58 trial (Multicenter Trial to Evaluate the Effect of Dapagliflozin on the Incidence of Cardiovascular Events). This analysis estimated the cost-effectiveness of empagliflozin versus canagliflozin, dapagliflozin, or SoC, in US adults with T2DM and established CV disease.Research design and methods Individual patient-level discrete-event simulation was conducted to predict time-to-event for CV and renal outcomes, and specific adverse events over patients’ lifetimes. Occurrence of events in EMPA-REG OUTCOME was estimated based on event-free survival curves with time-dependent covariates. An HR for canagliflozin or dapagliflozin versus empagliflozin on each clinical event was estimated from published CANVAS, DECLARE-TIMI 58, and EMPA-REG OUTCOME data using indirect treatment comparison. Public sources provided US costs and utilities.Results The model predicted longer survival for empagliflozin versus canagliflozin, dapagliflozin, and SoC mainly due to direct reduction in CV death. Empagliflozin dominated canagliflozin, yielding more quality-adjusted life years (QALYs; 0.38) at a lower cost (−US$306). Compared with dapagliflozin and SoC, empagliflozin yielded 0.50 and 0.84 incremental QALYs at US$1517 and US$27 539 incremental costs, yielding incremental cost-effectiveness ratios of US$3054/QALY and US$32 848/QALY, respectively.Conclusions Empagliflozin was projected to dominate canagliflozin and be highly cost-effective compared with dapagliflozin and SoC using US healthcare costs

The UMMS Community Engagement Committee

The mission of the UMMS Community Engagement Committee is to promote inter-professional community engagement focused on teaching and service. In teaching, we advance service learning; in service, we advance action that responds to community-identified need. Service-learning is a pedagogical strategy that integrates community-responsive service with instruction and reflection to enrich the learning experience, teach civic responsibility, and strengthen communities. The Committee has a diverse membership of faculty, staff and students from across the School of Medicine, Graduate Nursing School and Graduate School of Biomedical Sciences. Its work is accomplished by three sub-committees: Internal Relations, External Relations and Database. Recent activities of the Committee will be highlighted including the results of the Community Engagement Survey, promotion of and participation in the 2016 Greater Worcester CHIP (Community Health Improvement Plan) and the development of a new population clerkship placement in collaboration with the Joint Coalition on Health. We encourage participation in the CHIP and we are seeking collaboration and partnership with community organizations, groups and individuals; additional strategies to promote community engagement; and new members from the UMMS community

Deception in the Cyber-World

Like any other communication medium, cyber-space has been used for deception since its inception. Originally a medium that gave immediate global range to deceptive messages, it also provided a medium to contradict any deceptive message sent. Of course, messages are not necessarily true or false but convey an opinion about reality that the recipient accepts or does not. The main concern of managers of this information has been that the messages have not been corrupted by those with malevolent intent. Hence, at its simplest level the integrity of the message (in the information security sense) is the primary objective. With more complex messages the use of propaganda techniques that attempt to influence opinions are of concern. A medium such as the public Internet with its low cost of entry and ubiquitous access is ideal for this and, because of its multi-media and interactive format, gives a much better success rate that ‘conventional’ media. Cyber-space over the last few years has rapidly entered a new phase with almost universal use of mobile online devices that many individuals and organisations are becoming increasingly dependent on. In this environment two other developments have significant implications for the practice of deception which changes the degree to which it changes the relationship of machines, deception and humans. These new factors are: the development of neuroscience and its associated technologies, and networked robotics. These are examined in this chapter and the consequences for deception at the level of individuals and large groups are examined
