Wall shear rate (WSR) is an important stimulus for the brachial artery flow-mediated dilation (FMD) response. However, WSR estimation near the arterial wall by conventional Doppler is inherently difficult. To overcome this limitation, we utilised multi-gate Doppler to accurately determine the WSR stimulus near the vessel wall simultaneously with the FMD response using an integrated FMD system [Ultrasound Advanced Open Platform (ULA-OP)]. Using the system, we aimed to perform a detailed analysis of WSR-FMD response and establish novel WSR parameters in a healthy young population...

Foot and mouth disease (FMD) is an important transboundary disease in South-East Asia. Its control has been a priority in the region for at least 20 years, with extensive institutional support and capacity-building being provided by the international community through the World Organisation for Animal Health. This paper describes the FMD control and eradication programme in the Mekong region (Myanmar, Thailand, the Lao People's Democratic Republic, Cambodia and Vietnam) of South-East Asia and evaluates the FMD control programme in one of the region's countries, namely Cambodia...

A large-scale foot and mouth disease (FMD) epidemic in Japan in 2010 caused severe economic losses for livestock and related industries. In this paper, the authors develop a clear and usable framework to estimate the economic impact of this FMD outbreak. An economic analysis is then conducted by combining this framework with an epidemiological model. The framework estimates the direct and indirect costs to livestock and related industries by applying an input-output model, as well as by addressing expenditure on disease control...

Foot-and-mouth disease (FMD) poses a serious threat to the agricultural sector due to its highly contagious nature. Outbreaks of FMD can lead to substantial disruptions to livestock markets due to loss of production and access to international markets. In a previously FMD-free country, the use of vaccination to augment control of an FMD outbreak is increasingly being recognized as an alternative control strategy to direct slaughtering [stamping-out (SO)]. The choice of control strategy has implications on production, trade, and hence prices of the sector...

Takayasu arteritis, fibromuscular dysplasia (FMD), spontaneous arterial dissection, Raynaud's phenomenon, and chilblains are vascular conditions that are associated with an increased predisposition in women and are often underdiagnosed. Takayasu arteritis has an incidence rate of 2.6 cases per million individuals per year in the USA and predominantly affects women of childbearing age. HLA-B5 genetic locus is linked with Takayasu arteritis susceptibility. Methods to determine active disease are limiting; currently utilized clinical and imaging findings and laboratory tests are of limited value for this purpose...

Fibromuscular dysplasia (FMD) is an idiopathic, segmental, nonatherosclerotic, non-inflammatory vascular disease, which is often complicated by the occurrence of dissection. Although it is known to occur in all arteries, aortic involvement is relatively rare. To date, 33 cases of aortic FMD have been reported in available English literature, among which only three cases have been complicated by the occurrence of dissection. We describe the case of a 40-year-old woman diagnosed with aortic FMD complicated by the occurrence of a type A aortic dissection...

Fibromuscular dysplasia (FMD) is a disease associated with abnormalities of the arterial wall of medium-sized arteries. These abnormalities can lead to stenosis or less frequently to dissections or aneurysms. FMD is probably more frequent than initially thought. Nowadays, it is often a chance finding during a radiologic exam. In symptomatic cases, poor organ perfusion due to stenosis, dissection or aneurysm rupture may lead to the diagnosis. The aim of this non-systematic review illustrated with a clinical case is to present our current knowledge of FMD and to highlight the necessity of a standardized and multidisciplinary work-up to improve management of affected patients and understanding of the disease...

Vascular endothelial function declines across the menopause transition in women. We tested the hypothesis that reduced availability of the endothelial nitric oxide synthase [eNOS] substrate L-arginine is an underlying mechanism to vascular endothelial dysfunction across menopause stages. Endothelial function (brachial artery flow-mediated dilation [FMD]) and plasma markers of L-arginine metabolism (citrulline, N(G)-mono-methyl-ւ-arginine [L-NMMA] asymmetric dimethylarginine [ADMA] and N(G)-N('G)-dimethyl-l-arginine [SDMA]), were measured in 129 women: 36 premenopausal (33 ± 7 years), 16 early- (49 ± 3 years) or 21 late- (50 ± 4 years) perimenopausal, and 21 early- (55 ± 3 years) or 35 late- (61 ± 4 years) postmenopausal...

Accurate information on the geographic distribution of domestic animal populations helps biosecurity authorities to efficiently prepare for and rapidly eradicate exotic diseases, such as Foot and Mouth Disease (FMD). Developing and maintaining sufficiently high-quality data resources is expensive and time consuming. Statistical modelling of population density and distribution has only begun to be applied to farm animal populations, although it is commonly used in wildlife ecology. We developed zero-inflated Poisson regression models in a Bayesian framework using environmental and socioeconomic variables to predict the counts of livestock units (LSUs) and of cattle on spatially referenced farm polygons in a commercially available New Zealand farm database, Agribase...

Endothelium-dependent flow mediated dilation (FMD) and endothelium-independent dilation (GTN) are impaired at high altitude (5050 m), and FMD is impaired following acute exposure (<60-minutes) to normobaric hypoxia equivalent to ∼5050 m (∼FI O2  = 0.11). Whether glyceryl trinitrate (GTN)-induced dilation is impaired acutely, and whether FMD is impaired during milder hypoxia is unknown. Therefore, we assessed brachial FMD at baseline and following 30-minutes of mild (74 ± 2 mmHg PET O₂) and moderate (50 ± 3 mmHg PET O₂) normobaric hypoxia (n = 12) or normoxia (time-control trial; n = 10)...

BACKGROUND: India is undergoing rapid urbanization with simultaneous increases in the prevalence of cardiovascular disease (CVD). As urban areas become home to an increasing share of the world's population, it is important to understand relationships between the built environment and progression towards CVD. OBJECTIVE: We assessed associations between multiple measures of the built environment and biomarkers of early vascular aging (EVA) in the Population Study of Urban, Rural and Semiurban Regions for the Detection of Endovascular Disease and Prevalence of Risk Factors and Holistic Intervention Study (PURSE-HIS) in Chennai, India...

Foot-and-mouth disease (FMD), caused by foot-and-mouth disease virus (FMDV), is a highly contagious infectious disease that affects domestic and wild cloven-hoofed animals worldwide. VP2 is a structural protein of FMDV. In this study, an FMDV serotype-independent monoclonal antibody (MAb), 10B10, against the viral capsid protein VP2 was generated, and a series of GST fusion proteins expressing a truncated peptide of VP2 was subjected to Western blot analysis using MAb 10B10. Their results indicated that the peptide (8)TLLEDRILT(16) of VP2 is the minimal requirement of the epitope recognized by MAb 10B10...

As dysfunction of the vascular system is an early, modifiable step in the progression of many cardiovascular diseases, there is demand for methods to non-invasively monitor the health of the vascular system in clinical and research settings. Validated by very good agreement with more technical assessments of vascular function, like intra-arterial drug infusions and flow mediated dilation (FMD), the passive leg movement (PLM) technique has emerged as a powerful, yet relatively simple, test of peripheral vascular function...

INTRODUCTION: Patients with classical congenital adrenal hyperplasia (CAH) have increased cardiovascular risk, but the vascular and cardiac function during longitudinal corticoids replacement therapy is not known thoroughly. MATERIAL AND METHODS: Cross-sectional study of 19 Caucasian adults with CAH (age 23.7 ± 3.8 years; twelve males) compared to 20 healthy volunteers matched for origin, sex, age, and body mass index (BMI). All of the participants were assessed for flow mediated dilatation of the brachial artery (FMD), intima-media thickness of the common carotid artery (cIMT) and common femoral artery (fIMT), standard echocardiography, and global longitudinal left ventricular function using two-dimensional speckle-tracking echocardiography (LSTE)...

The foot-and-mouth disease virus (FMDV) afflicts livestock in more than 80 countries limiting food production and global trade. Production of foot-and-mouth disease (FMD) vaccines requires cytosolic expression of the FMDV 3C protease to cleave the P1 polyprotein into mature capsid proteins, but the FMDV 3C protease is toxic to host cells. To identify less toxic isoforms of the FMDV 3C protease, we screened 3C mutants for increased transgene output over wild-type 3C using a Gaussia luciferase reporter system...
