Single-Step Detection of the Influenza Virus Hemagglutinin Using Bacterially-Produced Quenchbodies.

Autor(es): Jeong, Hee-Jin; Dong, Jinhua; Ueda, Hiroshi
Fonte: Sensors (Basel);19(1)2018 Dec 23.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 30583603
Resumo: We have successfully generated a Quenchbody that enables the detection of the influenza virus hemagglutinin (HA), in a simple and convenient manner. By two-site labeling of the bacterially-produced anti-HA Fab with ATTO520, its fluorescence intensity was increased to 4.4-fold, in the presence of a nanomolar concentration of H1N1 HA. Our results indicate the potential use of this Quenchbody, as a sensor for the simple in situ detection of influenza A virus.

Resumo: Infective endocarditis (IE) is a life-threatening disease, establishing a diagnosis is often challenging. The aim of this prospective study was to evaluate and compare the diagnostic performance of the combined use of single photon emission tomography and computed tomography with technetium99m-hexamethylpropyleneamineoxime-labeled leukocytes (99mTc-HMPAO-SPECT/CT) with transthoracic echocardiography (TTE) in patients with suspected IE. We enrolled 40 consecutive patients (12 females, 28 mal (mais)

Mobile Fall Risk Assessment Solution for Daily-Life Settings.

Autor(es): Simila, Heidi; Immonen, Milla; Niemirepo, Timo
Fonte: Conf Proc IEEE Eng Med Biol Soc;2018: 1530-1533, 2018 Jul.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 30440684
Resumo: Prevention of falls requires accurate means for fall risk assessment in order to identify persons at risk. This paper introduces a novel mobile fall risk assessment solution for daily-life settings. The solution contains an Android application that uses acceleration sensor data received via Bluetooth LE connection. The application guides through a simple walk test, analyzes the acceleration data measured from the acceleration sensor attached to the lower back and gives feedback about the fa (mais)

The temporal dynamics of perceptual and conceptual fluency on recognition memory.

Autor(es): Wang, Wei; Li, Bingbing; Gao, Chuanji; Guo, Chunyan
Fonte: Brain Cogn;127: 1-12, 2018 Nov.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 30176534
Resumo: Recognition memory can be driven by both perceptual and conceptual fluency, but when and to what extent they contribute to recognition memory remains an open question. The present study used event-related potentials (ERPs) to investigate the neural correlates of perceptual and conceptual fluency, when they gave rise to recognition. We manipulated the perceptual and conceptual fluency of retrieval cues in the recognition test independently to obtain the effects of different types of fluency. (mais)

Biomarker Clinical Trials in Lung Cancer: Design, Logistics, Challenges, and Practical Considerations.

Fonte: J Thorac Oncol;13(11): 1625-1637, 2018 Nov.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 30194034
Resumo: Treatment for lung cancer has evolved in the past 3 decades starting with platinum-based chemotherapy as the standard of care, regardless of histology, in the early 1990s to the current age of biomarker-driven therapy. Consequently, clinical trials in lung cancer have evolved in response to this new shift of paradigm, leading to novel approaches that simultaneously shorten the development process and allow evaluation of multiple patient cohorts. Herein, we provide an overview of the landsca (mais)

Does feeding frequency during lactation affect sows' body condition, reproduction and production performance?

Autor(es): Poulopoulou, Ioanna; Eggemann, Anne; Moors, Eva; Lambertz, Christian; Gauly, Matthias
Fonte: Anim Sci J;89(11): 1591-1598, 2018 Nov.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 30246330
Resumo: The present study investigated whether a three-times compared to two-times feeding frequency during lactation affects sows' body condition, reproductive performance as well as growth performance of the piglets . In a commercial farm, eight groups (8-10 animals) with a total number of 68 sows were included in the study. During lactation, four groups received feed two times (treatment 2DF) and four groups three times daily (treatment 3DF). Within treatments, sows were classified into young (< (mais)

Surviving, not thriving: a qualitative analysis of parents' perceptions of physical activity participation for rurally residing children with a disability.

Autor(es): Robinson, Timothy; Wakely, Luke; Marquez, Jodie; Rae, Kym
Fonte: Rural Remote Health;18(3): 4536, 2018 08.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 30138036
Resumo: INTRODUCTION: Preliminary research suggests that rurally residing children with a disability seldom participate in the recommended 60 minutes of moderate-to-vigorous physical activity per day and face multiple barriers to participation. The purpose of this study was to explore parents' perceptions of physical activity participation of rurally residing children with a disability, including barriers and any factors that may facilitate their participation. METHODS: Participants were parents or (mais)

Methods: Patients recruited to the British Society for Rheumatology Biologics Register-RA with at least one episode of SI while on TNFi were included. The biologic treatment decision following SI was considered. A multivariable adjusted Cox pro (mais)

Resumo: Abstract Equine influenza is one of the major respiratory infectious diseases in horses. An equine influenza virus outbreak was identified in vaccinated and unvaccinated horses in a veterinary school hospital in São Paulo, SP, Brazil, in September 2015. The twelve equine influenza viruses isolated belonged to Florida Clade 1. The hemagglutinin and neuraminidase amino acid sequences were compared with the recent isolates from North and South America and the World Organisation for Animal Hea (mais)

Resumo: KEY POINTS: High-frequency stimulation (HFS) of the Schaffer collateral pathway activates metabotropic glutamate receptor 5 (mGluR5) signalling in the proximal apical dendrites of CA1 pyramidal neurons. The synaptic activation of mGluR5-mediated calcium signalling causes a significant increase in persistent sodium current (I ) in the dendrites. Increased I by HFS underlies potentiation of synaptic inputs at both the proximal and distal dendrite, leading to an enhanced probability of action (mais)
