CLEVELAND - Results from the DAWN stroke trial presented at the European Stroke Organization Conference (ESOC) provide compelling evidence that selected patients suffering a major ischemic stroke recovered significantly better with mechanical retrieval of the blood clot with medical therapy compared with medical therapy alone when initiated past the current guidelines of within 6 hours and up to 24 hours of the stroke. University Hospitals Cleveland Medical Center was one of the top seven recruiting sites in the multi-site study that enrolled a total of 206 patients in the nation. The results showed that patients treated with the retrieval system, known as mechanical thrombectomy, had significantly decreased post-stroke disability and improved functional independence at 90 days compared to medical management alone. "This is incredible," said Cathy Sila, MD, Director of UH's Comprehensive Stroke Center, and principal investigator of the study at the UH site. "Almost half of the patients (48.6 percent) receiving the thrombectomy therapy had a good outcome at 90 days after treatment--defined as the patients being independent in activities of daily living--as opposed to only 13.1 percent of the patients treated medically or with clot-busting drugs alone. This 35 percent difference may be higher than any level of benefit from any stroke trial." "Not only did the patients treated with mechanical thrombectomy dramatically improve during hospitalization, sometimes being able to walk and be discharged to home, but there was also a much lower risk of subsequent neurological worsening because of the poor blood flow to the brain," said Dr. Sila. "The number of patients needed to treat to achieve a good outcome was 2.8. This is a much greater chance of response than what was seen in trials that did not routinely use advanced brain imaging to guide treatment," she said. "We have long believed in the usefulness of MRI scans to define appropriateness of treatment. UH had been using a similar MRI protocol since 2010, five years before the DAWN trial began in 2015." Anthony Furlan, MD, Chairman of the Department of Neurology at UH and Case Western Reserve University School of Medicine, was on the DAWN study's steering committee and helped write the study protocol. "These results provide physicians who treat stroke with evidence of the benefits of thrombectomy even when administered out as far as 24 hours, and should help to make decisions clearer as to which patients to treat," said Dr. Furlan. "These positive outcomes of the DAWN trial represent a major change in patient selection for endovascular therapy for stroke," he said. In the study, researchers used neuroimaging to determine which patients would likely benefit from the procedure. According to Dr. Sila, they would examine how much brain tissue had suffered irreversible damage and how much might be able to be saved. If the amount of damaged tissue were no bigger than the size of a small apricot, researchers believed the patient could benefit from the therapy. Neuro-interventionists would then use a mechanical stent retriever called the Trevo Retriever to remove the blood clot, followed by treatment with the clot-busting medication. The study had been stopped earlier this year after an FDA-approved planned interim review by the independent Data Safety Monitoring Board (DSMB) of data from the first 200 patients enrolled nationally because there was such a dramatic difference between the two arms of the study. The study had been designed to enroll up to a maximum of 500 patients. Dr. Sila said that in Northeast Ohio, we have about 18,000 strokes per year. Stroke survivors commonly experience devastating disabilities and loss of independence due to impaired movement, paralysis, loss of speech and memory. Randomized clinical data has proven the benefit of mechanical thrombectomy with stent retrievers in helping patients with large vessel occlusion strokes, but these devices have only been indicated to reduce disability if used within six hours of stroke onset. "For patients presenting with stroke symptoms beyond six hours, the benefit of clot retrieval using a stent retriever was unknown," said Dr. Furlan. "Now we have evidence that for patients who present to the hospital outside of the six hour time window could have a better chance for an independent life with improved clinical outcomes. Although this is great news, earlier treatment is always better because with stroke 'time is brain.'" The study was supported by Stryker, which produces the Trevo Retriever, a tiny stent-shaped medical device that is attached to a thin wire. The retriever is designed to ensnare the blood clot to remove it from a blood vessel. UH is working with Case Western Reserve University to develop the Cleveland Brain Health Initiative, linking this kind of leading edge neuroscience work from CWRU, UH, Cleveland Clinic, MetroHealth Medical Center and the Louis Stokes Cleveland VA Medical Center to advance progress therapy and treatment of devastating neurological diseases.

The purpose of the study is to demonstrate superior clinical outcomes at 90 days with Stryker's Trevo Retriever plus medical management compared to medical management alone in appropriately selected patients treated six to 24 hours after last seen well. The Trevo Retriever indication within the DAWN Trial is currently approved for investigational use only by the U.S. Food and Drug Administration in the United States under an Investigational Device Exemption (IDE) study approval.

The Trevo Retriever is a tiny stent-shaped medical device that is attached to a thin wire. In a minimally invasive procedure that utilizes X-ray, the physician navigates the retriever from the femoral artery (located in the upper leg) to the blocked blood artery in the brain. The retriever is designed to ensnare the blood clot and remove it from the body. Originally cleared by the FDA in 2012 for the revascularization of patients experiencing ischemic stroke, the Trevo Retriever has been used in thousands of patients worldwide. Stryker's Trevo Retriever was the only mechanical thrombectomy device used in this trial. An animation of Stryker's Trevo Retriever is available here: https:/ An ischemic stroke occurs when an artery in the brain becomes blocked by a blood clot or other substance such as plaque, a fatty material. Blood vessels carry blood, oxygen and nutrients throughout the body and to the brain. When the brain is deprived of blood and oxygen, it fails to work properly. Depending on the severity of the stroke and the area of the brain affected, loss of brain function or death may occur. According to the World Heart Federation, ischemic stroke contributes to nearly six million deaths around the globe.

Despite their ecological significance as decomposers and their evolutionary significance as the most speciose eusocial insect group outside the Hymenoptera, termite (Blattodea: Termitoidae or Isoptera) evolutionary relationships have yet to be well resolved. Previous morphological and molecular analyses strongly conflict at the family level and are marked by poor support for backbone nodes. A mitochondrial (mt) genome phylogeny of termites was produced to test relationships between the recognised termite families, improve nodal support and test the phylogenetic utility of rare genomic changes found in the termite mt genome. Complete mt genomes were sequenced for 7 of the 9 extant termite families with additional representatives of each of the two most speciose families Rhinotermitidae (3 of 7 subfamilies) and Termitidae (3 of 8 subfamilies). The mt genome of the well supported sister-group of termites, the subsocial cockroach Cryptocercus, was also sequenced. A highly supported tree of termite relationships was produced by all analytical methods and data treatment approaches, however the relationship of the termites + Cryptocercus clade to other cockroach lineages was highly affected by the strong nucleotide compositional bias found in termites relative to other dictyopterans. The phylogeny supports previously proposed suprafamilial termite lineages, the Euisoptera and Neoisoptera, a later derived Kalotermitidae as sister group of the Neoisoptera and a monophyletic clade of dampwood (Stolotermitidae, Archotermopsidae) and harvester termites (Hodotermitidae). In contrast to previous termite phylogenetic studies, nodal supports were very high for family-level relationships within termites. Two rare genomic changes in the mt genome control region were found to be molecular synapomorphies for major clades. An elongated stem-loop structure defined the clade Polyphagidae + (Cryptocercus+. termites), and a further series of compensatory base changes in this stem-loop is synapomorphic for the Neoisoptera. The complicated repeat structures first identified in Reticulitermes, composed of short (A-type) and long (B-type repeats) defines the clade Heterotermitinae + Termitidae, while the secondary loss of A-type repeats is synapomorphic for the non-macrotermitine Termitidae. © 2012 Elsevier Inc.

Taphonomic biases dictate how organisms are represented in the fossil record, but their effect on studies of vertebrate diversity dynamics is poorly studied. In contrast to the high diversity and abundance of small-bodied animals in extant ecosystems, small-bodied dinosaurs are less common than their large-bodied counterparts, but it is unclear whether this reflects unique properties of dinosaurian ecosystems or relates to taphonomic biases. A new, fully domed pachycephalosaurid dinosaur, Acrotholus audeti, from the Santonian of Alberta predates incompletely domed taxa, and provides important new information on pachycephalosaur evolution and the completeness of the ornithischian fossil record. Here we provide the first empirical evidence that the diversity of small-bodied ornithischian dinosaurs is strongly underestimated based on ghost lineages and the high proportion of robust and diagnostic frontoparietal domes compared with other pachycephalosaur fossils. This suggests preservational biases have a confounding role in attempts to decipher vertebrate palaeoecology and diversity dynamics through the Mesozoic. © 2013 Macmillan Publishers Limited.

Background: Herbivore coexistence on the Late Cretaceous island continent of Laramidia has been a topic of great interest, stemming from the paradoxically high diversity and biomass of these animals in relation to the relatively small landmass available to them. Various hypotheses have been advanced to account for these facts, of which niche partitioning is among the most frequently invoked. However, despite its wide acceptance, this hypothesis has not been rigorously tested. This study uses the fossil assemblage from the Dinosaur Park Formation of Alberta as a model to investigate whether niche partitioning facilitated herbivorous dinosaur coexistence on Laramidia. Specifically, the question of feeding height stratification is examined in light of the role it plays in facilitating modern ungulate coexistence.Results: Most herbivorous dinosaur species from the Dinosaur Park Formation were restricted to feeding no higher than approximately 1 m above the ground. There is minimal evidence for feeding height partitioning at this level, with ceratopsids capable of feeding slightly higher than ankylosaurs, but the ecological significance of this is ambiguous. Hadrosaurids were uniquely capable of feeding up to 2 m quadrupedally, or up to 5 m bipedally. There is no evidence for either feeding height stratification within any of these clades, or for change in these ecological relationships through the approximately 1.5 Ma record of the Dinosaur Park Formation.Conclusions: Although we cannot reject the possibility, we find no good evidence that feeding height stratification, as revealed by reconstructed maximum feeding heights, played an important role in facilitating niche partitioning among the herbivorous dinosaurs of Laramidia. Most browsing pressure was concentrated in the herb layer, although hadrosaurids were capable of reaching shrubs and low-growing trees that were out of reach from ceratopsids, ankylosaurs, and other small herbivores, effectively dividing the herbivores in terms of relative abundance. Sympatric hadrosaurids may have avoided competing with one another by feeding differentially using bipedal and quadrupedal postures. These ecological relationships evidently proved to be evolutionarily stable because they characterize the herbivore assemblage of the Dinosaur Park Formation through time. If niche partitioning served to facilitate the rich diversity of these animals, it may have been achieved by other means in addition to feeding height stratification. Consideration of other feeding height proxies, including dental microwear and skull morphology, may help to alleviate problems of underdetermination identified here. © 2013 Mallon et al.; licensee BioMed Central Ltd.

Ongoing research into the biostratigraphy of the upper Campanian Dinosaur Park Formation (DPF) of Alberta has demonstrated that megaherbivorous dinosaur taxa (ankylosaurs, ceratopsids, hadrosaurids) are not homogeneously distributed throughout the unit. This has compelled proposals of different, informal assemblage zone schemes, and the hypothesis that faunal turnover was driven by environmental change associated with marine transgression. The current study tests previous zonation schemes in addition to the hypothesis of turnover pulses in the DPF. Clustering and ordination methods are used to demonstrate the existence of two broad assemblage zones within the DPF, each of which lasted ~. 600. Ka: a lower zone characterized by the presence of the ceratopsid Centrosaurus apertus and the hadrosaurids Corythosaurus, and an upper zone characterized by the presence of the ceratopsid Styracosaurus albertensis and the hadrosaurid Prosaurolophus maximus. These zones can be further sub-divided, based on the distributions of rarer or shorter-lived ankylosaur, ceratopsid, and hadrosaurid species, into ~. 300. Ka sub-zones. Canonical correspondence analysis is used to explore the association between the turnover of the megaherbivorous dinosaurs and various palaeoevironmental proxies. Megaherbivorous dinosaur turnover most closely corresponds to that of fossil palynomorphs. However, none of the palaeoenvironmental proxies explains dinosaur distribution better than a simple time gradient, suggesting that dinosaur turnover was not inextricably linked to environmental change as predicted by the turnover pulse hypothesis. © 2012 Elsevier B.V.

Anchiceratops is a chasmosaurine ceratopsid from the Upper Cretaceous Horseshoe Canyon Formation (HCF) of Alberta. It is distinguished primarily by its unique parietosquamosal frill ornamentation and possibly by the presence of a ventrally flexed olfactory bulb of the brain. Although Anchiceratops is known from at least ten partial skulls, only two of these have been formally described. These skulls are not stratigraphically segregated, but they differ markedly in their proportions (e.g., supraorbital horncore and frill dimensions), causing previous authors to account for this disparity with reference to either interspecific or sexual differences. Both of these hypotheses assume that variation in Anchiceratops is dimorphic; however, this assumption has never been tested with reference to all available material. The present study describes all material from the HCF that can be positively attributed to Anchiceratops, and tests the assumption of dimorphism by subjecting this material to a series of morphometric analyses. We find no compelling evidence for dimorphism in Anchiceratops, although sample size is still too small for convincing statistical support. We conclude that there is a single, variable species of Anchiceratops, A. ornatus. Average sedimentation rates for the HCF suggest that A. ornatus is a particularly long-lived species compared with other ceratopsids (1.5-2.0 Ma), and the paleoecological implications of this are discussed. A cladistic analysis that includes the new data presented here indicates that Anchiceratops is more closely related to Chasmosaurus than to Triceratops, in contrast with previous studies. © 2011 by the Society of Vertebrate Paleontology.

Disentangling ontogenetic from interspecific variation is key to understanding biodiversity in the fossil record, yet information on growth in the ceratopsid subfamily Chasmosaurinae is sparse. Here, we describe the partial skull of a juvenile chasmosaurine, attributed to Arrhinoceratops brachyops, within the context of more mature specimens of this species, to better understand the ontogenetic transformations therein. We show that as A. brachyops matured, the postorbital horncores became longer and shifted from a posterior to an anterior inclination, the delta-shaped frill epiossifications became lower and fused to the underlying frill, and the face became more elongate. In these respects, A. brachyops closely resembled Triceratops, suggesting that these ontogenetic changes may have been common to all long-horned chasmosaurines. However, an event-paired cladistic analysis of Chasmosaurinae using a standardized matrix of 24 developmental characters reveals that the relative timing of ontogenetic events in Arrhinoceratops was more like that of Chasmosaurus, particularly in the relatively late reduction in scalloping around the frill margins. Thus, the ontogenetic similarities between Arrhinoceratops and Triceratops appear to be plesiomorphic, partly related to the retention of the elongate postorbital horncores, which are primitive for Ceratopsidae. This study elucidates the otherwise contentious evolutionary relationships of Arrhinoceratops, and highlights the importance of ontogenetic data for resolving phylogenies when morphological data from adults alone are inadequate. © 2015 The Linnean Society of London.

The Cleveland Heights, Ohio–based car dealership Motorcars Honda was named the first carbon-neutral automotive dealership anywhere in the world at a recent awards ceremony in the city, according to a new press release. The new “Carbon Neutral Award” status was granted by British Petroleum (BP), ironically, at an event “for more than 5,000 residents and businesses at Wade Oval in University Circle.” What has Motorcars Honda done to date to deserve such a distinction? Apparently, it installed solar photovoltaic (PV) panels as well as “LG VRF systems heating/cooling system, and LED lighting fixtures,” amongst other things. “We are eliminating the carbon footprint for every new & used cars sold, all of our employees cars, parts truck, rental cars, shuttle van, and the owners personal travel tied to work,” stated Trevor Gile, Managing Partner at Motorcars Honda. “Five years ago, we never thought that we would be going down this path, but as our employees became more involved and concerned with the environment, we started to learn about some of the various options available to help.” Here’s some background on the dealership: “Motorcars Honda is an automotive dealership in Cleveland Heights, OH. Founded in 1971. Motorcars Honda has received many awards including Honda’s Environmental Leadership Platinum Award — 1 of only 10 dealers in the country to win this award, Winner of 2015 Ohio Business of the Year (Green Energy of Ohio), Winner of 2016’s “Dealer of the Year” for Ohio (DealerRater) and ranked top 100 dealerships to work for in America (Automotive News), just to name a few.” It’s hard to believe this is the first carbon-neutral car dealership in the world, but I guess that also makes a bit of sense.   Drive an electric car?
