description: We compute the quasinormal modes associated with decay of the massless scalar filed around a small Schwarzschild-Anti-de-Sitter black hole. The computations shows that when the horizon radius is much less than the anti-de-Sitter radius, the imaginary part of the frequency goes to zero as $r_+^{d-2}$ while the real part of $ω$ decreases to its minimum and then goes to $d-1$. Thus the quasinormal modes approach the usual AdS modes in the limit $r_+ -> 0$. This agrees with suggestions of Horowitz et al (Phys.Rev. D62 024027 (2000)).

description: We study isotropic antiferromagnetic Heisenberg chains coupled by antiferromagnetic Ising interaction as an effective spin model for the ytterbium aluminum perovskite YbAlO$_3$. Using the density-matrix renormalization group (DMRG) method we calculate the magnetization curve, local spin, central charge, and dynamical spin structure factors in the presence of magnetic field. From the fitting of the experimental magnetization curve, the effective intrachain and interchain couplings are estimated as $J=2.3$K and $J_{\rm ic}=0.8$K, respectively. We can quantitatively explain the experimental observations: (i) phase transition from antiferromagnetic to incommensurate order at field 0.35T, and (ii) quantum critical behaviors at the saturation field of 1.21T. Furthermore, the low-energy excitations in the experimental inelastic neutron scattering spectra can be well described by our DMRG results of the dynamical structure factors.

description: Genetic factors contribute to about a half of coronary artery diseases. During the last several decades, some studies suggested that non-O blood group and thrombomodulin polymorphism −33G>A are the risk factors of coronary artery disease especially in Asia. There was no prior study in Indonesia regarding this issue. Hence, this study was designed to investigate the correlation of ABO polymorphism and thrombomodulin polymorphism −33G>A with the incidence of acute myocardial infarction (AMI). A total of 192 subjects were enrolled in this case control study. AMI patients were diagnosed based on World Health Organization criteria. Healthy patients were subjects with AMI risk factor without any sign and symptoms of AMI. Patients with diabetes mellitus, cancer, and arrhythmia were excluded from this study. Genotyping for both polymorphisms was performed by PCR RFLP methods. The result of this study suggested that ABO polymorphism and thrombomodulin polymorphism −33G>A were not risk factors of AMI, p= 0.727 and 𝑝p = 0.699, respectively. Furthermore, the analysis to identify the synergy of these polymorphisms failed to prove their correlation with AMI (p= 0.118). Conclusively, this study showed that ABO polymorphism and thrombomodulin polymorphism −33G>A were not risk factors of AMI.

description: Villa Rica is one of the most important coffee-producing districts in Peru. In Villa Rica there are several marketing channels: intermediaries, private companies, cooperatives and associations. The intermediaries focus solely on higher prices while marketing organizations offer benefits to their members. The main aim of this paper is to analyze the socio-economic characteristics that influence coffee farmers to join a formal organization vs. those who distribute their product through intermediaries. A survey of 60 producers was carried out in June 2011 in Villa Rica. A binary logistic model was used in order to show how these characteristics affect farmers’ choice of which marketing channel to use to distribute their product. The results demonstrated that farmers who are keen to receive technical assistance participate in the marketing organizations. These coffee marketing organizations should look for ways to improve the extension component through training and knowledge transfers to smallholder farmers.

description: Selbstorganisiertes und gemeinschaftliches Wohnen liegt im Trend und in den letzten Jahren sind in zahlreichen Städten viele neue Projekte des gemeinschaftlichen Bauens und Wohnens entstanden. Als Nische der Wohnversorgung ermöglichen Hausprojekte Wohnformen und Lebensmodelle, die in den Standardlösungen des privaten und öffentlichen Wohnungsbaus nur selten realisiert werden können. Doch selbstverwaltete und gemeinschaftliche Wohnprojekte unterscheiden sich nicht nur im Zuschnitt der Wohneinheiten und der Nutzung von Gemeinschaftsflächen von klassischen Wohnbauprojekten, sondern auch in der Art und Weise, wie sie entstehen. In diesem Beitrag, der die Ergebnisse des Forschungsprojekts „Bausteine für ein Neues soziales Wohnen“ (im Rahmen der Incoming Research Fellowship „Immobilienwirtschaft und Standortentwicklung“ an der TU Wien) zusammenfasst, schauen wir auf einige Besonderheiten solcher Projekte und nehmen dabei vor allem die organisatorischen und ökonomischen Aspekte in den Blick. Auf der Basis von Fallstudien des Neubaus von selbstorganisierten und gemeinschaftlichen Hausprojekten stellen wir dar, wie solche Neubauvorhaben geplant, finanziert, gebaut und verwaltet werden und skizzieren so die Konturen des Neuen Sozialen Wohnens.

description: Abstract: Mammalian embryos change shape dramatically upon implantation. The cellular and molecular mechanism underlying this transition are largely unknown. Here, we show that this transition is directed by cross talk between the embryonic epiblast and the first extra-embryonic tissue, the trophectoderm. Specifically, we show via visualisation of a Cdx2-GFP reporter line and pharmacologically mediated loss and gain of function experiments that the epiblast provides FGF signal that results in differential fate acquisition in the multipotent trophectoderm leading to the formation of a tissue boundary within this tissue. The trophectoderm boundary becomes essential for expansion of the tissue into a multi-layered epithelium. Folding of this multi-layered trophectoderm induces spreading of the second extra-embryonic tissue, the primitive endoderm. Together, these events remodel the pre-implantation embryo into its post-implantation cylindrical shape. Our findings uncover how communication between embryonic and extra-embryonic tissues provides positional cues to drive shape changes in mammalian development during implantation.

description: We investigate the orderability properties of fundamental groups of 3-dimensional manifolds. Many 3-manifold groups support left-invariant orderings, including all compact P^2-irreducible manifolds with positive first Betti number. For seven of the eight geometries (excluding hyperbolic) we are able to characterize which manifolds' groups support a left-invariant or bi-invariant ordering. We also show that manifolds modelled on these geometries have virtually bi-orderable groups. The question of virtual orderability of 3-manifold groups in general, and even hyperbolic manifolds, remains open, and is closely related to conjectures of Waldhausen and others.

 Comments. Without examination of the holotype we are unable to define C. simplex. The holotype is likely in Vienna, however we have thus far been unable to borrow Curtonotum type material from NHMW.
 This species is included in the key presented in Hendel’s 1913 treatment of Curtonotum, however no description is included. Because C. simplex keys out early in Hendel’s key, all that can be gleaned is that the species lacks punctate markings on the thorax and has two prominent katepisternal setae. In the description of C. perplexum (Hendel, 1932, under the name C. impunctatum), the body, wings and legs of C. simplex are described as being “brownish black”. Given these limited details it is not possible to make any assumptions regarding this species’ placement in the Curtonotum phylogeny, or produce a diagnosis for its identity, and therefore is treated here as incertae sedis.
 Giglio-Tos (1895), and subsequently Aldrich (1905), reports Curtonotum simplex (under the names Diplocentra simplex and Cyrtonotum simplex, respectively) from Tuxpan, Mexico. This is almost certainly based on a misidentification, no Curtonotum species are known to range from Mexico to South America.

description: Separating electron and phonon thermal conductivity components is imperative for understanding the principle thermal transport mechanisms in metals and highly desirable in many applications. In this work, we predict the mode-dependent electron and phonon thermal conductivities of 18 different metals at room-temperature from first-principles. Our first-principles predictions, in general, agree well with experimental data. We find that the phonon thermal conductivity is in the range of 2 - 18 $W/mK$, which accounts for 1% - 40% of the total thermal conductivity. It is also found that the phonon thermal conductivities in transition metals and transition-intermetallic-compounds (TICs) are non-negligible compared to noble metals due to their high phonon group velocities. Besides, the electron-phonon coupling effect on phonon thermal conductivity in transition metals and intermetallic compounds is stronger than that of nobles, which is attributed to the larger electron-phonon coupling constant with a high electron density of state within Fermi window and high phonon frequency. The noble metals have higher electron thermal conductivities compared to transition metals and TICs, which is mainly due to the weak electron-phonon coupling in noble metals. It is also shown that the Lorenz ratios of transition metals and transition-intermetallic-compounds hold larger deviations from the Sommerfeld value $L_0=2.44 \times 10^{-8} W ΩK^{-2}$. We also find the mean free paths (MFPs) for phonon (within 10 nm) are smaller than those of electron (5 - 25 nm). The electrical conductivity and electron thermal conductivity are strongly related to the MFPs of the electron.

description: The essential oil of Massoia (Massoia aromatica Becc., Lauraceae) bark is a potential immunomodulator in vitro. This study evaluated the potential immunomodulatory effects of Massoia bark infusion on the nonspecific immune response (phagocytosis) of Wistar rats. For the in vitro assay, macrophages were treated with the freeze-dried infusion at the concentrations of 2.5, 5, 10, 20, or 40 g/mL media. For the in vivo assay, two-month-old male Wistar rats were divided into five groups. The baseline group received distilled water at the dose of 1 mL/100 g body weight (BW), with the herbal product containing Phyllanthus niruri extract that was administered as the positive control at the dose of 0.54 mL/rat. The treatment groups received the infusion at a dose of 100, 300, or 500 mg/100 g BW. Treatments were given orally every day for 14 days. The ability of macrophage cells to phagocyte latex was determined as phagocytic index (PI), and it was observed under microscopy with 300 macrophages. The in vitro study revealed that the phagocytic activity of the infusion-treated macrophages significantly increased in comparison with that of the control macrophages in a concentration-dependent manner. Among all of the treatment concentrations, the concentration of 40 g/mL provided the highest activity with a PI value of 70.51 1.11%. The results of the in vivo assay confirmed those of the in vitro assay. The results of the present study indicate that Massoia bark can increase the phagocytic activity of rat macrophage cells.

description: Commercial overexploitation and climate change can alter the physiology and behaviour of affected marine organisms, although depending on the environment, species, and severity, intraspecific phenotypic response to such changes can vary greatly. Under the Pace-Of-Life Syndrome (POLS) hypothesis, behaviour, physiology, and life history traits can be linked and thus affected both directly and indirectly by selection targeting any aspect of behavioural physiology. However, such links are often understudied in tropical marine fish, with work needed to better understand the impacts of fisheries and climate change on fish stocks. Moreover, tropical regions have greater reliance on fisheries, thus investigations should focus on species with economic value to ensure social benefits. This study aimed to partially address this need by measuring the behaviour (boldness and activity), metabolism and swimming performance (Ucrit) of schoolmaster snapper Lutjanus apodus in Eleuthera, The Bahamas. I found a strong positive correlation between boldness and activity with high repeatability of behavioural metrics, and two groupings present, consistent with ‘proactive’ and ‘reactive’ behavioural types. Proactive and reactive behavioural types also differed significantly in terms of Ucrit values with reactive individuals showing increased swimming performance. No significant differences were found between behavioural types for any of the metabolic proxies. These results present preliminary research into the links, or lack thereof, between behaviour and physiology in an economically valuable tropical marine fish. Further investigation into this potential model species would allow refinement of predictions relating to the success of proactive/reactive types under overexploitation and climate change.

description: The organic market is growing at a steady pace of 20 percent annually; this farming method can bring several advantages to the consumers and also to the farmers. Among other things organic farming does not have to rely on access to external inputs such as fertilizer and pesticides because the farmers make use of their own resources. This not only represents a friendlier environment to the farmer or the land but also can be cheaper. The aim of this study is to find out the yield differential between three productions systems (organic, biofertilized and conventional) of guava crops in Zitacuaro, Michoacan, Mexico. The results indicated that the most profitable crop in terms of production costs and profits on Zitacuaro´s region is the biofertilized crop that takes up the sustainable practices combined with conventional practices in a lesser proportion. While organic and conventional crops shows a slide difference between them.

description: Abstract: Phosphorene, monolayer or few-layer black phosphorus, exhibits fascinating anisotropic properties and shows interesting semiconducting behavior. The synthesis of phosphorene nanosheets is still a hot topic, including the shaping of its two-dimensional structure into nanoribbons or nanobelts. Here we report electrochemical unzipping of single crystalline black phosphorus into zigzag-phosphorene nanobelts, as well as nanosheets and quantum dots, via an oxygen-driven mechanism. The experimental results agree well with our theoretical calculations. The calculation for the unzipping mechanism study suggests that interstitial oxygen-pairs are the critical intermediate species for generating zigzag-phosphorene nanobelts. Although phosphorene oxidation has been reported, lengthwise cutting is hitherto unreported. Our discovery of phosphorene cut upon oxidation represents a previously unknown mechanism for the formation of various dimensions of phosphorene nanostructures, especially zigzag-phosphorene nanobelts. It opens up a way for studying the quantum effects and electronic properties of zigzag-phosphorene nanobelts.

description: Blueberry wines may have a multitude of health benefits, but few studies have quantified the health-enhancing antioxidants, total phenols, anthocyanins and flavonoids in blueberry wines, especially the Southern highbush blueberry wine, in comparison to grape wines and fruit liquors. This study was initiated to fill such a gap by measuring the antioxidant capacity and key phytonutrients of Southern highbush blueberry wine as compared to red, Rose and white wines and fruit liquors. The Oxygen Radical Absorbance Capacity (ORAC) of the Southern highbush blueberry wine tested in this study ranged from 18.54 to 25.48 mmol TE/L, with an average of 22.57 ± 2.92 mmol TE/L. This was higher than the ORAC values of over 80% of the red wines and 100% of the Rose and white wines reported in literature. A majority of the red wines were higher, but all the Rose and white wines and most fruit liquors were lower in total phenolic content than the Southern highbush blueberry wine. Anthocyanin contents of the blueberry wines were generally comparable to those of the red wines. Results show that blueberry wines could be more potent than most red, Rose and white wines in health enhancement and disease prevention from the antioxidant perspective.

description: Environmental goods and services which are not priced in traditional economic markets are typically excluded from decision making approaches which are based on monetary values. Benefit-cost analysis, for example, employs monetary estimates of values with and without the project under consideration. The exclusion of environmental values in monetary terms often results in a variety of ad hoc approaches to incorporate these elements in decision making. These approaches range from the application of zero values for the environmental services to the use of measures such as equivalent energy values. Over the past 30 years economists have attempted to derive appraoches to incorporate monetary values of environmental amenities into decision making frameworks. Monetary measures are used as a "metric" so that both market and non-market goods can be represented on a common base. This paper reviews the approaches currently in use to estimate values for environmental goods and services. Direct (contingent valuation) and indirect (travel cost, hedonic price and risk valuation) approaches are examined. The successes and failures are outlined. The conclusions suggest that there are classes of environmental amenities that can be assessed during these monetary tools and there are other classes for which the current techniques are questionable. Avenues for further research are identified.

description: The first stable object to develop in the low-mass star formation process has long been predicted to be the first hydrostatic core (FHSC). Despite much effort, it has still yet to be definitively observed in nature. More specific observational signatures are required to enable observers to distinguish the FHSC from young, faint, but more evolved protostars. Here we present synthetic spectral line observations for CO, SO, CS and HCO$^+$ that were calculated from radiation (magneto)hydrodynamical models, chemical modelling and Monte Carlo radiative transfer. HCO$^+$ $(1-0)$ and SO $(8_7 - 7_6)$ spectra of the FHSC show variations for observations at a low inclination which may allow a candidate FHSC to be distinguished from a more evolved object. We find that the FHSC outflow is unlikely to be detectable with ALMA, which would discount the observed sources with slow outflows that are currently identified as candidate FHSCs. We compare the results of simulated ALMA observations with observed candidate FHSCs and recommend Oph A SM1N and N6-mm as the most promising candidates to follow up.

description: Abstract: We report a simple histological study on skin biopsies from young domestic sheep following each step in transformation from skin to parchment production. During the recreation of historical parchment manufacture, histological analyses were conducted; before and after lime treatment, hair removal, and stretching. Sections were fixed and stained using a variety of histological stains to identify the presence of different molecular classes and the fibrous proteins, collagen and elastin. The results reveal surprisingly few histological changes in most steps in the production process. However, very visible changes in the supramolecular ordering of skin macromolecules (elastin, collagen) occur during the final stage of parchment production when stretched on the frame. Collagen fibres and hair follicles were all strongly re-oriented in the direction of strain. Surprisingly despite the thinness of the lambskin and the exhaustive treatment in lime, not all fats were saponified and even in the final product Oil Red O stained fat bodies were detectable on the hair side of the skin. We believe this study will help compensate for the lack of sources on microscopic changes in parchment during the recreation of its historical manufacture.

description: The major determinants of cereal import demand in seventy-four less developed countries (LDCs) were analyzed through the use of an econometric cross-sectional model. Key explanators included the level of income and degree of urbanization, financial capacity proxies, and domestic grain supply variables. A major innovation involved the analysis of the impact of income distribution on LDC cereal import demand in 1986 and 1987 for a more restricted sample of twenty-three nations. These developing countries exhibit a greater than proportional increase in cereal imports due to an increase in the income share of the poorest 40 percent of their populations. The inclusion of regional slipe and intercept drummies in the cereal import demand model also provided improved results. High levels of government debt appear to have inhibited cereal importation in nations in South America, but not in Asia and Africa. In all three continental regions, particularly in Africa, there is a positive relationship between food aid and cereal imports. The model predicts cereal imports for nations in Asia and South America more satisfactorily than those in Africa. Finally, the resuults support the view that improvements in income distribution in developing nations would considerably stimulate cereal imports.

description: Caesalpinia sappan L (Sappanwood) contains antibacterial compounds and antioxidants that inhibit the growth of microbes. This study aimed to investigatethe microbiological and physicochemical qualities of pasteurized milk supplemented with 0, 2, 4, 6 and 8% (w/v) sappan wood extract. Data were analyzed using a completely randomized design factorial followed by the Duncan’s new multiple range test. Preliminary analysis showed that sappan wood extract contained 44.66 ± 0.09 mg/100g phenols, 0.18 ± 0.01 mg/100mg flavonoids, 46.42 ± 0.23 mg/100g tannins, and antioxidant activity at 85.82 ± 0.25%. The addition of sappan wood extract significantly increased the antioxidant activity (P<0.05) of pasteurized milk during storage. Pasteurized milk supplemented with sappan wood extract had a lower total bacterial count (P<0.05) than that of unsupplemented pasteurized milk, and supplemented milk showed strong antibacterial activities against Escherichia coli, Shigella flexneri, Salmonella thypimurium, Staphylococcus aureus, and Listeria monocytogenes.The addition of sappan wood slightly increased the protein content but did not affect pH, and viscosity. It is concluded that the addition of sappan wood extract increased the microbiological quality and maintained the physicochemical quality of pasteurized milk, thus extending the product’s shelf-life.

description: Canadian cattle finishers who wish to hedge their production must use the U.S. futures markets. Prior research has sugggested that Canadian Cattle investors cannot successfully hedge using the Chicago Mercantile Exchange (CME) to manage risk due to variable basis assumed to be caused in part by variable exchange rates. This article reevaluates the use of the CME by Canadian cattle investors feeding heavy feeder steers to slaughter. The study evaluates basis variability, the effect of exchange rates on basis variability and hedging effectiveness. It is shown that Alberta basis is less variable in the latter 1980s than the latter 1970s, Alberta basis is not more variable than the basis at Omaha, variance minimizing hedge ratios are similiar between Alberta and Omaha, and changes in exchange rates have little relationship with changes in Alberta basis. These results suggest that the CME has a role in risk management in Canadian cattle feeding. An historical cattle feeding simulation in Alberta during 1980 to 1989 using heavy feeder steers shows that hedging reduces risk by up to 43%. Exchange rate risk is very low and contributes less than 7% to risk. Basis makes up slightly more than 50% of risk. These results indicate that the CME can be used to manage risk for the cattle investor in Alberta although basis risk is still significant.

description: $^{229}$Th is the only nucleus currently under investigation for the development of a nuclear optical clock (NOC) of ultra-high accuracy. The insufficient knowledge of the first nuclear excitation energy of $^{229}$Th has so far hindered direct nuclear laser spectroscopy of thorium ions and thus the development of a NOC. Here, a nuclear laser excitation scheme is detailed, which makes use of thorium atoms instead of ions. This concept, besides potentially leading to the first nuclear laser spectroscopy, would determine the isomeric energy to 40 $μ$eV resolution, corresponding to 10 GHz, which is a $10^4$ times improvement compared to the current best energy constraint. This would determine the nuclear isomeric energy to a sufficient accuracy to allow for nuclear laser spectroscopy of individual thorium ions in a Paul trap and thus the development of a single-ion nuclear optical clock.

description: Realistic approaches to improving the quality of life in Canada's resource dependent communities are being hampered by philosophical ambiguities, misplaced assumptions, and poorly defined terms of reference. A dominant development theme in communities of this type has been diversification, particularly in terms of the economic base. However, for a variety of reasons, resource dependent communities in this country have experienced very little diversification. A major obstacle lies in the locus of decision-making. Most natural resource develoeprs are transnational firms which maximize profits by manipulating labor inputs and extraction costs across national boundaries. Consequently, even communities predicated upon renewable resources may find their goal of long-term stability undermined by global circumstances. This inherent antagonism between philisophy and economic reality seems to have been largely ignored by those who see chronic instability in these communities as essentially deriving from deficiencies in local decision making and entrepreneiural ethic. Moreover, there is evidence to suggest that government policy has been counterproductive in fostering a belief that solutions lie in local empowerment. But local engranchisement seldom has any impact on the global environment within which decisions affecting extraction and marketing of the resource are made. Non renewable resource based communities are in an even more precarious position. In both cases, any hope of economic diversification tends to be totally dependent upon the fortunes of the core resource. The drive for sustainability in resource dependent communities has also indirectly fostered a 'fortress mentality'. The alienation and powerlessness created by dependence upon a single employer has encouraged many communities to strive for autonomy, particularly in terms of infrastructure, in the assumption that long-term stability derives from institutional completeness. Again, some government programs have aggravated this rationale by encouraging communities to become unrealistically and inappropriately entrepreneurial in what is seldom an entrepreneurial environment. The outcome is frequently disillusionment and a costly duplication of scare resources. This paper argues that a dominant cultural ethic in this country, which places a high priority on individual security, has compromised the importance of economic diversification programs.

description: Macrocyclic oligothiophenes and their π-expanded derivatives constitute versatile building blocks for the design of (supra)molecularly engineered active interfaces, owing to their structural, chemical, and optoelectronic properties. Here, it is demonstrated how resonant tunneling effect induces single molecular isomerization in a 2D crystal, self-assembled at solid–liquid interfaces under ambient conditions. Monolayers of a series of four π-expanded oligothiophene macrocycles are investigated by means of scanning tunneling microscopy and scanning tunneling spectroscopy (STS) at the interface between their octanoic acid solutions and the basal plane of highly oriented pyrolytic graphite. Current–voltage characteristics confirm the donor-type character of the macrocycles, with the highest occupied molecular orbital and the lowest unoccupied molecular orbital (LUMO) positions consistent with time-dependent density functional theory calculations. Cyclic STS measurements show the redox isomerization from Z,Z-8T6A to its isomer E,E-8T6A occurring in the 2D crystal, due to the formation of a negatively charged species when the tunneling current is in resonance with the LUMO of the macrocycle.

description: This paper serves to elucidate the nature of toric duality dubbed in hep-th/0003085 in the construction for world volume theories of D-branes probing arbitrary toric singularities. This duality will be seen to be due to certain permutation symmetries of multiplicities in the gauged linear sigma model fields. To this symmetry we shall refer as ``multiplicity symmetry.'' We present beautiful combinatorial properties of these multiplicities and rederive all known cases of torically dual theories under this new light. We also initiate an understanding of why such multiplicity symmetry naturally leads to monodromy and Seiberg duality. Furthermore we discuss certain ``flavor'' and ``node'' symmetries of the quiver and superpotential and how they are intimately related to the isometry of the background geometry, as well as how in certain cases complicated superpotentials can be derived by observations of the symmetries alone.

description: Abstract: Background: The objective of this study was to explore the associations between ultrasonographic and radiographic joint scores and levels of arterial CVD risk markers in patients with osteoarthritis (OA). Secondly, to compare the levels of arterial CVD risk markers between OA phenotypes and controls. Method: The “Musculoskeletal pain in Ullensaker” Study (MUST) invited residents of Ullensaker municipality with self-reported OA to a medical examination. OA was defined according to the American College of Rheumatology (ACR) criteria and phenotyped based on joint distribution. Joints of the hands, hips and knees were examined by ultrasonography and conventional radiography, and scored for osteosteophytes. Hands were also scored for inflammation by grey scale (GS) synovitis and power Doppler (PD) signal. Control populations were a cohort of inhabitants of Oslo (OCP), and for external validation, a UK community-based register (UKPC). Pulse pressure augmentation index (AIx) and pulse wave velocity (PWV) were measured using the Sphygmocor apparatus (Atcor®). Ankel-brachial index (ABI) was estimated in a subset of patients. In separate adjusted regression models we explored the associations between ultrasonography and radiograph joint scores and AIx, PWV and ABI. CVD risk markers were also compared between phenotypes of OA and controls in adjusted analyses. Results: Three hundred and sixty six persons with OA were included (mean age (range); 63.0 (42.0–75.0)), (females (%); 264 (72)). Of these, 155 (42.3%) had isolated hand OA, 111 (30.3%) had isolated lower limb OA and 100 (27.3%) had generalized OA. 108 persons were included in the OCP and 963 persons in the UKPC; (mean age (range); OCP: 57.2 (40.4–70.4), UKPC: 63.9 (40.0–75.0), females (%); OCP: 47 (43.5), UKPC: 543 (56.4%). Hand osteophytes were associated with AIx while GS and PD scores were not related to CVD risk markers. All OA phenotypes had higher levels of AIx compared to OCP in adjusted analyses. External validation against UKPC confirmed these findings. Conclusions: Hand osteophytes might be related to higher risk of CVD. People with OA had higher augmented central pressure compared to controls. Words 330.
