Clinical profile and outcome of patients with cardiac myxomas treated surgically.A 20-year experience with long-term follow-up

Introduction . Primary neoplasms of the heart are very rare, benign cardiac myxomas being the most common. The aim of this study was to present the clinical profile and long-term outcome of patients (pts) who underwent surgical resection of cardiac myxoma. Material and methods . Between 1981 and 2000, 21 pts (12 female and 9 male), mean age 43.9 ± 14.5 years (range:21-74 yrs) underwent surgery for cardiac myxoma. Before surgery we performed physical examination, ECG, chest Xray, echocardiography (M + 2D) and coronary artery angiography (in patients over 40 years of age). All pts were operated by median sternotomy in moderate hypothermia (26-28°C) with the use of cardiopulmonary bypass. At the end of the follow up clinical examination and echocardiography (M + 2D) were performed. Results . Before operation 19 pts (90.5%) presented with cardiac signs related to mitral orifice obstruction. Six of them (28.6%) were NYHA class II, 8 (38.1%) - class III and 5 (23.8%) - class IV. Events of embolism occurred in 6 pts (28.6%). Ten pts (47.6%) had nonspecific systemic or constitutional symptoms, including permanent fever and significant weight loss. Two pts (9.5%) were asymptomatic, diagnosis being established accidentally. In all cases definite diagnosis was made by echocardiography. The myxomas were located in the left atrium in 18 pts (85.7%), in the right atrium in 2 pts (9.6%) and in the right ventricle in one pt (4.7%). One pt (4.7%) died in hospital because of low cardiac output syndrome and, eventually, multiorgan failure. The mean follow up of 5.4 ± 4.0 years (range: 3 mos - 20 yrs) was completed by all pts. Two pts died during follow up for noncardiac-related reasons. The cumulative survival rate calculated from the Kaplan-Meier curve was 85.2% after 5 years. No tumor recurrences were observed. At the end of follow up all pts were in NYHA class I or II. Conclusions . Most preoperative symptoms of heart myxomas are related to mitral valve obstruction. The final diagnosis can be made by echocardiography. Surgical resection is a safe and curative therapy with a low risk of recurrence.
Ecological palaeoecology and conservation biology: controversies, challenges, and compromises

Until recently, ecological palaeoecology (a part of long-term ecology) and conservation biology were considered two separate subjects with little relevance to each other. With the shift from description and evaluation in conservation biology in the 1960s–1990s to the paradigm of ‘conservation in a rapidly changing world’ in the late 1990s, conservationists began to realise the importance of the temporal dimension in developing conservation strategies to allow for landscape and ecosystem change. Despite this paradigm shift, ecological palaeoecology is still largely ignored by conservation biology. I explore why this may be and outline recent advances in the subject of direct relevance to conservation science. I present nine questions of critical importance to conservation that palaeoecology can answer. Inevitably during this honeymoon phase of conservation biology and palaeoecology, there are controversies, challenges, and compromises. I outline these and suggest how some can be overcome by breakdown of the largely artificial boundaries between landscape history, cultural history, conservation, and palaeoecology, and by the appreciation that all can make important contributions to our understanding of people and nature and conservation in the face of changing land-use, environment, and landscapes.

odelling the innovation value chain

Innovation events – the introduction of new products or processes – represent the end of a process of knowledge sourcing and transformation. They also represent the beginning of a process of exploitation which may result in an improvement in the performance of the innovating business. This recursive process of knowledge sourcing, transformation and exploitation comprises the innovation value chain. Modelling the innovation value chain for a large group of manufacturing firms in Ireland and Northern Ireland highlights the drivers of innovation, productivity and firm growth. In terms of knowledge sourcing, we find strong complementarity between horizontal, forwards, backwards, public and internal knowledge sourcing activities. Each of these forms of knowledge sourcing also makes a positive contribution to innovation in both products and processes although public knowledge sources have only an indirect effect on innovation outputs. In the exploitation phase, innovation in both products and processes contribute positively to company growth, with product innovation having a short-term ‘disruption’ effect on labour productivity. Modelling the complete innovation value chain highlights the structure and complexity of the process of translating knowledge into business value and emphasises the role of skills, capital investment and ces in t firms’ other resour
Direct synthesis of antimicrobial coatings based on tailored bi-elemental nanoparticles

Ultrathin coatings based on bi-elemental nanoparticles (NPs) are very promising to limit the surface-related spread of bacterial pathogens, particularly in nosocomial environments. However, tailoring the synthesis, composition, adhesion to substrate, and antimicrobial spectrum of the coating is an open challenge. Herein, we report on a radically new nanostructured coating, obtained by a one-step gas-phase deposition technique, and composed of bi-elemental Janus type Ag/Ti NPs. The NPs are characterized by a cluster-in-cluster mixing phase with metallic Ag nano-crystals embedded in amorphous TiO2 and present a promising antimicrobial activity including also multidrug resistant strains. We demonstrate the flexibility of the method to tune the embedded Ag nano-crystals dimension, the total relative composition of the coating, and the substrate type, opening the possibility of tailoring the dimension, composition, antimicrobial spectrum, and other physical/chemical properties of such multi-elemental systems.
Study of gallbladder lesions and its relationship with serum lipid profile

Background: Gallbladder disease is one of the most common gastrointestinal diseases. Various studies have shown association between gallstone and alteration in serum lipids. The objective of this study was to evaluate histological patterns of cholecystectomy specimens and compare serum lipid profile of gallstone patients with controls.Methods: This study was conducted over a period of two years (April 2016 to April 2018). Records of 287 specimens who underwent cholecystectomy were analysed in which gallstones were found only in 186 patients. Out of 186 patients with gallstones, records of serum lipid profile were available in 32 patients which were compared with 32 control of similar age. Independent t- test was used to compare the data between cases and control.Results: Out of 287 cases, 68 were male and 219 were female with male to female ratio of 1:3.2. The predominant histopathological lesion was chronic cholecystitis (73.17%). Malignancy was observed in 0.7% cases. Serum total cholesterol, triglycerides and low density lipoprotein cholesterol were found to be higher and statistically significant in patients with gallstone compared to controls (p value 0.024, <0.001and 0.016 respectively). Serum High density lipoprotein cholesterol was lower in gallstone patient than in control but not statistically significant (p value 0.23). Conclusions: Chronic cholecystitis was the most common histopathological lesion. Serum total cholesterol, triglyceride and low density lipoprotein cholesterol level were elevated and statistically significant in patients with gallstone.

Flying PIV investigation of vortex packet evolution in perturbed boundary layers

A turbulent boundary layer with zero pressure gradient of Reτ=2500 was perturbed using a single spanwise cylinder array with H/δ=0.2 (H=500) and aspect ratio H/D=4 mounted on the bounding surface. Both fixed location and tracking measurements were performed using particle image velocimetry (PIV) in streamwise-spanwise planes up to 7δ downstream at a wall-normal location of z=300. The spacing of the cylinder array was varied from 0.2δ to 0. 8δ, and the 0. 6δ spacing case, which matched the dominant spanwise mode in the unperturbed flow, showed the most stable downstream organization which persisted beyond 7δ in the streamwise direction. The flying PIV method allowed us to track specific vortical structures in the streamwise direction of range -2<x/δ<7, corresponding to a time scale of order 12δ/U∞. The flying PIV results showed that approaching packets lost their organization immediately downstream of the 0.2δ array but regained it 2δ downstream on a time scale of order 3δ/U∞, suggesting that the outer layer organization propagated inward into the log region. With larger spacing, the cylinders sometimes enhanced the organization of existing packets and generally redirected packets into the spanwise location midway between cylinders. The interactions between packets and cylinder wakes were discussed in three scenarios based on the relative spanwise distance between the cylinder and upstream packet.
Wire-line log-based stratigraphy of flood basalts from the Lopra-1/1A well, Faroe Islands

The present study shows that it is possible to use conventional borehole logs to perform a detailed lithological/stratigraphical division of a column of subaerially extruded basalt. A stratigraphical division of the subaerial flood basalts penetrated by the Lopra-1/1A well has been carried out using new wire-line logging data measured in 1996 in the interval 200–2489 m depth. Resistivity data acquired in the interval 200–2178 m depth during 1981 after the initial drilling of the Lopra-1 well have also been incorporated. Eighty-six individual flow units, 18 compound flows and two dolerite dykes have been identified by combining the NPHI porosity, RHOB density, P-, S- and Stonely-sonic transit time, calliper and resistivity logs. Fifty-two sedimentary/tuffaceous layers have also been identified using the CGR and SGR gamma ray and potassium logs in combination with the aforementioned logs. Within the flow units, sonic velocity, density and resistivity are highest in the core where porosity is lowest. This relation is reversed in the uppermost and basal zones of the flow units. The sonic velocity in the core seems to be independent of the thickness of the flow unit. Porous zones seem abundant in some cores and the total section of cores containing porous zones constitutes more than 70% of the thickness of its flow unit, but where porous zones are absent the core makes up only roughly 50% of the thickness of the flow. It is suggested that the flow units with porous cores represent aa flows (88% of the flow units) and the others pahoehoe flows (12% of the flow units). The log pattern of the flow units (crust, core and basal zone) is similar to log patterns reported from other basalt plateaux. However the patterns in Lopra-1/1A show a larger variation than elsewhere, suggesting that the flow units are more complex vertically than previously thought. Statistical analysis of P-, S- and Stonely-waves, RHOB, NPHI, resistivity, gamma and calliper logs has been carried out. Cross-plots based on the lithological divisions have been produced that show a pronounced reduction in scattering versus P-sonic transit time and P- and S-sonic, RHOB and NPHI logs correlate with depth. The geochemical logs do not reflect the cyclic structure of the flow units and probably represent the primary composition of the basalt. The thorium log especially indicates flow units with high and low radioactivity and it is suggested that a minimum of 36 flow fields form the logged part of the lower basalt series. Dolerite units described in previous works have been confirmed based on the combined interpretation of wire-line logs. The log data suggest that the subaerially extruded basalt has its base at a depth of approximately 2490 m and that a hyaloclastite succession is found below that depth. The transition from subaerially extruded basalt to hyaloclastite produces a negative acoustic impedance and it is found that the transition corresponds to a negative reflection interpreted on VSP surveys from 1988 and 1994.
From License Raj to Market Forces: The Determinants of Industrial Structure in India after Reform

This paper explores the relationship between factor endowments, technology and industrial structure, using a panel data-set of Indian industries across states, industries and time. Factor endowments and technology are found to be significantly related to industry shares, and this is robust to controlling for the slow adjustment of industrial structure. I also consider the impact of the liberalization of the Indian economy beginning in 1985 and 1991 on the relationship between these variables. While industrial structure is always positively related to technological advantage, factor endowments play an increasingly significant role after liberalization.
An Empirical Study of Performance Appraisal and Career Opportunities

Using survey data from a large international oil company, this econometric study explores the perceptions ofperformance appraisal and career opportunities on one hand, and how this is dependent on variation in propertiesand characteristics of the local working environment on the other hand. Perceptions indicate that performanceand payoff are better balanced among women than among men. Moreover, the connection between perceivedachievement and appreciation is strengthened by time of service for leaders, but not for employees innon-managerial positions. Finally, perceptions of performance appraisal and career opportunities depend oncharacteristics of the local work environment, with positive influence from key phenomena like changecapability, competency focus, trust and identity.
Genotype by environment interaction of some faba bean genotypes under diverse broomrape environments of Tigray, Ethiopia

Advanced breeding lines with acceptable resistance and tolerance levels to broomrape is an important way of decreasing yield loss. The objective of this research was to assess the yield stability of faba bean genotypes under diverse broomrape (Orobanche crenata) prone production environments. Six faba bean genotypes were tested across six environments. The AMMI analysis showed significant (P<0.01) genotype, environment and genotype by environment interaction and the environment explained higher sum of square for the response variable grain yield. The AMMI one gives the best model fitness for the grain yield and broomrape number. Using the AMMI 1 biplot, polygon view of the GGE biplot and comparison of genotypes based on ideal genotype, the genotype ILB4358 was higher yielder and stable with lower Orobanche number followed by the genotype Sel.F5/3382/2003-4. Using the AMMI biplot analysis E3 (Adigolo, 2011) and E4 (Adigolo, 2012) were unfavorable environments, while, E1 (Awliegara, 2011), E2 (Awliegara,), E5 (Kolatsihidi, 2011) and E6 (Kolatsihidi, 2012) were favorable testing environments. Key words: AMMI, broomrape, environments, genotypes, GGE, faba bean.
On Detecting Sudden Changes in the Unconditional Volatility of a Time Series

The present study highlights the drawback of using Sanso, Arago and Carrion’s (2004) AIT-ICSS algorithm in detecting sudden changes in the unconditional volatility when long memory is present in volatility. Simulation experiments show that the AIT-ICSS test is severely oversized and exhibits low power when long memory is present in volatility.
SEROPREVALENCE OF EQUINE BRUCELLOSIS: FIRST REPORT IN BANGLADESH

Despite the endemicity of brucellosis, there is no report on the equine brucellosis in Bangladesh. The Rose Bengal Test (RBT) was used to determine the seroprevalence of Brucella antibodies amongst 112 horses from different areas of Bangladesh. The overall seroprevalence of equine brucellosis was 1.79%. The prevalence recorded in Ghatail area was 3.45% and there was no positive reactor in Shakipur and Savar areas. Sex wise prevalence showed that the prevalence was 3.08%in female and 0.00% in male horse. Only the adult (>3 years of old) horses showed the positive RBT reaction (2.35%), whereas young (<3 years of old) horses did not showed positive RBT reaction. The present study reports the first serological prevalence of Brucella infection in horses in Bangladesh. There is need for the inclusion of horses in brucellosis surveillance and control strategies in Bangladesh to safeguard people from high risk.
The Fed-Induced Political Business Cycle

Given that Nordhaus' political business cycle theory is relevant at election cycle frequency and that its validity can change over time, we consider wavelet analysis especially suited to test the theory. For the postwar U.S. economy, we exploit wavelet methods to demonstrate whether there actually exists an opportunistic political business cycle in monetary policy by allowing for time-varying behavior and by introducing the frequency-domain perspective. Our results indicate an inclination of the Federal Reserve to cut the Funds rate prior to presidential elections except for the 1990s. Moreover, such political manipulation is shown to significantly affect output in not only the famous Burns-Nixon era but also the Volcker-Reagan era. The outcomes are robust even when the effects of government spending are controlled for.
The North Atlantic Subpolar Gyre in Four High-Resolution Models

The authors present the first quantitative comparison between new velocity datasets and high-resolution models in the North Atlantic subpolar gyre [1U10° Parallel Ocean Program model (POPNA10), Miami Isopycnic Coordinate Ocean Model (MICOM), 1U6° Atlantic model (ATL6), and Family of Linked Atlantic Ocean Model Experiments (FLAME)]. At the surface, the model velocities agree generally well with World Ocean Circulation Experiment (WOCE) drifter data. Two noticeable exceptions are the weakness of the East Greenland coastal current in models and the presence in the surface layers of a strong southwestward East Reykjanes Ridge Current. At depths, the most prominent feature of the circulation is the boundary current following the continental slope. In this narrow flow, it is found that gridded float datasets cannot be used for a quantitative comparison with models. The models have very different patterns of deep convection, and it is suggested that this could be related to the differences in their barotropic transport at Cape Farewell. Models show a large drift in watermass properties with a salinization of the Labrador Sea Water. The authors believe that the main cause is related to horizontal transports of salt because models with different forcing and vertical mixing share the same salinization problem. A remarkable feature of the model solutions is the large westward transport over Reykjanes Ridge [10 Sv (Sv 10 6 m 3 s 1 ) or more].
A Priori Gradient Estimates for Bounded Generalized Solutions of a Class of Variational Problems with Linear Growth

Given an integrand f of linear growth and assuming an ellipticity condition of the form D^{2}f(Z)(Y,Y)\geq c(1+\left|Z\right|^{2})^{-\frac{\mu}{2}}\left|Y\right|^{2}, 1<\mu\leq3, we consider the variational problem J[w]=\int_{\Omega}f(\nabla w)dx\rightarrow{\normalcolor min} among mappings w:\mathbb{R}^{n}\supset\Omega\rightarrow\mathbb{R}^{N} with prescribed Dirichlet boundary data. If we impose some boundedness condition, then the existence of a generalized minimizer u* is proved such that \int_{\Omega^{\text{'}}}\left|\nabla u*\right|\log^{2}(1+\left|\nabla u*\right|^{2})dx\leq c(\Omega\text{'}) for any \Omega\Subset\Omega. Here the limit case \mu=3 is included. Moreover, if \mu<3 and if f(Z)=g(\left|Z\right|^{2}) is assumed in the vectorvalued case, then we show local C^{1,\alpha}-regularity and uniqueness up to a constant of generalized minimizers. These results substantially improve earier constributions of [BF3] where only the case of exponents 1<\mu<1+2/n could be considered.
The Effect of Dividend Initiation on Shortrun Return in Indonesia Stock Market : An Event Study with Propensity Score Matching Approach

Dividend initiation policy offers a relatively unique practical and conceptual characteristics compared to those of regular dividend. This study aims at investigating whether initial dividend policy of Indonesian firms affects short-run stock return, while further exploring the implementation of a new event study approach, propensity score matching, as an experimental-like design. This approach is based on actual rather than estimated abnormal return commonly used in traditional approach. Applying this new approach, this study found no significant abnormal returns around dividend initiation announcement by firms listed in Indonesia Stock Exchange. The findings imply that the dividend initiation behavior of Indonesian firms is proved not fully to follow the theoretical framework of signaling model, a dividend model which is basically developed primarily based on regular dividend behavior. The results partly contradict those findings mostly resulted from researchs conducted in advanced market context but seem to support contextuality argument of dividend policy. From methodological perspective, this study identified that the use of propensity score matching approach needs a large number of firms from which control firms are selected, accordingly the study conducted in market with limited number of listed firms such as in Indonesia could generates selection problem of control firms that optimally match treated firms.
