Background-Treatment with renin-angiotensin system (RAS) inhibitors might restrain the structural/electrical remodeling associated with atrial fibrillation (AF). Limited evidence exists regarding the potential benefits of RAS inhibition post-acute myocardial infarction (AMI) in patients with AF. This study sought to assess the association between RAS inhibition and all-cause mortality and new-onse

In a series of experiments the pyrolytic effects of the heating induced during the hypervelocity impact (HVI) of small projectiles of high TOC mudrock were observed. Impacts at these high speeds (km s-1) release sufficient energy to vaporise metal projectiles, and the temperatures created greatly exceed the pyrolysis temperatures typically employed during laboratory studies of the thermal alterati

Aims To examine whether baseline fasting plasma glucose (FPG) modifies the prognostic role of left ventricular (LV) mass, geometric pattern, and diastolic function, for prediction of cardiovascular morbidity and mortality. Methods Population-based cohort study comprising of 1047 men and 456 women with preserved ejection fraction, included between 2002 and 2006, who underwent echocardiography based

The excellent performance of metal foams is well-recognized in the thermal and energy fields. This paper presents an investigation on the convective heat transfer and thermal performance of microchannel heat sinks with different structures of metal foams, such as Y-shaped, metal foam attached to fins, combined metal foams. The inlet Reynolds number is ranging from 170 to 554 and the porosity of th

Type of Study: This is a longitudinal, case-control clinical trial. Objectives: This study aims to track recovery time following a vocal loading task (VLT) imposing vocal fatigue and to explore if patients with functional dysphonia (FD) are worse affected by vocal loading, and if these patients take longer than others to recover. Methods: Fifty (n = 50) female participants in four vocal subgroups

The objective of the research presented in this paper was to investigate how different characteristics of whey protein microparticles (MWP) added to milk as fat replacers influence intermolecular interactions occurring with other milk proteins during homogenisation and heating. These interactions are responsible for the formation of heat-induced aggregates that influence the texture and sensory ch

The flow field design of current collectors is a significant issue, which greatly affects the mass transport processes of reactants/products inside fuel cells. Especially for proton exchange membrane (PEM) fuel cells, an appropriate flow field design is very important due to the water balance problem. In this paper, a wavy surface is employed at the cathode flow channel to improve the oxygen mass

The Inter-American Court of Human Rights (I-ACtHR) has developed remarkable jurisprudence for the protection of the right to communal property of indigenous and tribal communities with respect to the ancestral lands that they possess and traditionally used-natural resources, in order to guarantee their cultural and economic survival in the Americas. This article critically analyses the legal regim

Flying insects frequently navigate through environments of different complexity. In this study, buff-tailed bumblebees (Bombus terrestris L.) were trained to fly along tunnels of different widths, from 60 to 240 cm. In tunnel widths of 60 and 120 cm, bumblebees control their lateral position by balancing the magnitude of translational optic flow experienced in the lateral visual field of each eye.

The purpose of this study was to develop a computer-based method for automatic detection and localization of coronary artery disease (CAD) in myocardial bull's-eye scintigrams. Methods: A population of 135 patients who had undergone both myocardial 99mTc-sestamibi rest-stress scintigraphy and coronary angiography within 3 mo was studied. Different image data reduction methods, including pixel aver

Purpose: The technocratic and medicalized model of healthcare is rarely optimal for patients. By connecting two different studies we explore the possibilities of increasing quality of life in cancer care.Methods: The first study captures survival strategies in a historically isolated Arctic village in Norway resulting in Momentary contentment theory, which emerged from analysing four years of part

Immunoprotection of islets using bioisolator systems permits introduction of allogeneic cells to diabetic patients without the need for immunosuppression. Using TheraCyte™ immunoisolation devices, we investigated two rat models of type 1 diabetes mellitus (T1DM), BB rats and rats made diabetic by streptozotocin (STZ) treatment. We chose to implant islets after the onset of diabetes to mimic the pr

Purpose Many city logistics initiatives have failed to become economically sustainable. The purpose of this paper is to explain the impacts of cost, revenue and goods flow variables on the economic performance of a business model for city logistics. Design/methodology/approach A cost/benefit analysis, with data from transport providers and the municipality, on a six-month pilot implementation of a

Background More than half of cardiovascular mortality occurs outside the hospital, mainly due to consistently low survival rates from out-of-hospital cardiac arrest. Methods This is a prospective, nested, case-control study derived from the Västerbotten Intervention Programme and the World Health Organization's Multinational Monitoring of Trends and Determinants in Cardiovascular Disease study in

Part of the justification for an integrated view of speech and gestures ( (( is their temporal coordination. Gestures generally coincide with or precede, but rarely follow lexical affiliate (McNeill, 1992). How synchrony impacts listeners remains less explored, despite potential relevance for video communication and virtual conversational agents. ERP studies suggest that temporal alignment affects
