Hao Guo, Pengpeng Yan, Chen Cheng, Yao Li, Junjie Chen, Yong Xu, Jie Xiang
Resting state functional brain networks have been widely studied in brain disease research. Conventional network analysis methods are hampered by differences in network size, density and normalization. Minimum spanning tree (MST) analysis has been recently suggested to ameliorate these limitations. Moreover, common MST analysis methods involve calculating quantifiable attributes and selecting these attributes as features in the classification. However, a disadvantage of these methods is that information about the topology of the network is not fully considered, limiting further improvement of classification performance...

The blueberry is recognised as a source of phenolic compounds that have beneficial effects on human health; however, they possess low bioavailability and can be degraded by gastrointestinal conditions. Encapsulation has been widely used to mitigate these disadvantages; Gum Arabic (GA) and Corn Syrup Solids (CSS) are common carriers used in this technique. The aim of this study was to evaluate the effect of Blueberry Extract (BE), carriers and their mixtures on the kinetic growth and maximal growth rate of probiotics and pathogenic bacteria...

Tooth transposition is one of the most difficult dental anomalies to treat in the dental clinic. Several factors must be taken into account with a view of making the best decision. The aim of this study was to discuss treatment modalities for tooth transposition, their advantages and disadvantages. Additionally, it aims at presenting a clinical case of transposition between canine and lateral incisor in the upper quadrant on the right side. The treatment of choice was extraction of one transposed tooth. A multidisciplinary approach involving Orthodontics, Cosmetic Dentistry, and Periodontology was necessary to allow proper esthetic and functional outcomes to be achieved...

Bugs and vulnerabilities in binary executables threaten cyber security. Current discovery methods, like fuzz testing, symbolic execution and manual analysis, both have advantages and disadvantages when exercising the deeper code area in binary executables to find more bugs. In this paper, we designed and implemented a hybrid automatic bug finding tool-Ffuzz-on top of fuzz testing and selective symbolic execution. It targets full system software stack testing including both the user space and kernel space. Combining these two mainstream techniques enables us to achieve higher coverage and avoid getting stuck both in fuzz testing and symbolic execution...

BACKGROUND: A pervasive and persistent finding is the health disadvantage experienced by those in food insecure households. While clear associations have been identified between food insecurity and diabetes risk factors, less is known about the relationship between food insecurity and incident type 2 diabetes. The objective of this study is to investigate the association between household food insecurity and the future development of type 2 diabetes. METHODS: We used data from Ontario adult respondents to the 2004 Canadian Community Health Survey, linked to health administrative data (n = 4,739)...

Current methane gas leak detection technology uses infrared imaging in the medium wave (MW) or long wave (LW) bands, essentially applying cooled infrared detectors. In this study, a simplified three-layer radiative transfer model is adopted based on methane gas detection theory, considering background radiation, atmospheric infrared absorption, gas absorption, and emission characteristics to analyze the contrast of methane gas thermography in different infrared bands. The analysis results suggest that under certain conditions, the 6...

OBJECTIVE: Rheumatoid arthritis (RA) is associated with chronic inflammation. The suppression of inflammation is key to the treatment of RA. Glucocorticoids (GCs) are classical anti-inflammatory drugs with several disadvantages such as poor water solubility and low specificity in the body. These disadvantages are the reasons for the quick elimination and side effects of GCs in vivo. Micelles are ideal carriers for GCs delivery to inflamed synovium. We set out to improve the targeting and pharmacokinetic profiles of GCs by preparing a targeting micelle system...

Non-opioid analgesics are commonly used to treat mild and moderate acute and chronic pain. They can be used as monotherapy; however, they have greater efficacy in combination with weak and strong opioids. Unlike opioids, long-term use of non-steroidal anti-inflammatory drugs does not lead to physical dependence. One of the main disadvantages of the NSA is the risk of gastrointestinal side effects, especially bleeding into the digestive tract. This is increased especially in ulcerative disease and in higher doses, but also in the elderly (over 65 years), also with concomitant administration of corticosteroids, anticoagulants or other NSAIDs...

This paper aims to improve activity recognition systems based on skeletal tracking through the study of two different strategies (and its combination): (a) specialized body parts analysis and (b) stricter restrictions for the most easily detectable activities. The study was performed using the Extended Body-Angles Algorithm , which is able to analyze activities using only a single key sample. This system allows to select, for each considered activity, which are its relevant joints , which makes it possible to monitor the body of the user selecting only a subset of the same...

A new surgical technique of intra-tumoural ligation for the treatment of low-flow vascular malformations in the head and neck region is proposed. Ninety patients with diffuse low-flow vascular malformations diagnosed clinically and/or radiologically were treated surgically with the corset suturing technique. All patient records and clinical photographs were reviewed retrospectively. Significant clinical results were obtained: a reduction of the turnout tumour mass and a return of the regional facial outline was evident within 4 weeks after surgery...

BACKGROUND: Substance use is a well-known public health problem, but population-based research on migrants' substance use in Europe is limited. Factors related to the cultural background and current life situation might influence substance use among migrants. Here, the prevalence of substance use in Russian, Somali and Kurdish migrants in Finland is reported in comparison with the general population, and the associations between substance use and socio-economic and migration-related background factors among migrants are analysed...

Objectives: A well-documented paradox is that Hispanics tend to live longer than non-Hispanic Whites (NHW), despite structural disadvantages. We evaluate whether the "Hispanic paradox" extends to more comprehensive longitudinal aging classifications and examine how lifecourse factors relate to these groupings. Methods: We used biennial data (1998-2014) on adults 65-years and older at baseline from the Health and Retirement Study. We use joint latent class discrete time and growth curve modeling to identify trajectories of aging, and multinomial logit models to determine whether US-born (USB-H) and Foreign-born (FB-H) Hispanics experience healthier styles of aging than non-Hispanic Whites (NHW), and test how lifecycle factors influence this relationship...

Invasive aquatic weed management is one of the biggest challenges in the field of solid waste management. Eichhornia crassipes, Pistia stratiotes and Hydrilla verticillata (L.f.) Royle pose some of the world's most noted aquatic weed problems. Previously reported studies on management of H. verticillata, a submersed aquatic plant, have shown that temporary removal, chemical treatment or biological control methods each have advantages and disadvantages. Removal programs that propose to compost harvested H. verticillata biomass may provide a novel technique to manage this issue...

Health information and communication technologies (ICTs) are increasingly used but little is known about routine exposure to health information from ICTs and its associations with health behaviors. A territory-wide population-based dual landline and mobile telephone survey was conducted in 2016 in Hong Kong, where smartphone ownership and Internet access are among the most prevalent, easiest and fastest in the world. Health information exposure from traditional sources (television/radio/newspaper/magazine), Internet websites, social media sites and instant messaging (IM); and information on smoking, alcohol consumption and physical activity were recorded...

Saeed Akkad, Christopher J Serpell
As more evidence emerges supporting the possibility that nonsteroidal anti-inflammatory drugs, especially aspirin (acetyl salicylic acid), might have a role in the prevention and management of certain types of cancer, there have been several attempts to fabricate salicylic acid-based polymers that can be employed in the targeted therapy of tumors. The primary disadvantage so far has been in use of nontherapeutic polymeric backbones that constitute the majority of the therapeutic particle's size. The focus of this research is the creation of a biodegradable polymer consisting only of salicylic acid, and its use as the main building block in targeted nanotherapeutics that would consequently provide both high local dose and sustained release of the active moiety...

OBJECTIVE: Introduction: Medical researchers, who are non-native English speakers, are facing now the growing need to publish their research results in international journals switching to an English-only policy, to apply for grants and scholarship, but at the same time this puts many authors whose native language is not English at a disadvantage compared to their English-speaking counterparts. The aim: This paper aims at analysing the existing parameters of academic writing proficiency of medical undergraduate and postgraduate students; elucidating current approaches to develop academic writing competency and to promote academic multi-literacy of junior researchers, and outlining the general recommendations to improve the quality and sophistication of their writing by incorporating the principles and achievements of academic writing pedagogy into the system of medical training...

Researches on CRISPR/Cas (clustered regularly interspaced short palindromic repeats/CRISPR-associated genes) systems, that are adaptive immunity systems encoded by prokaryotes, have promoted the development of new genome-editing tools. Bacteriophages are not only the driving elements for the evolution of prokaryotes' CRISPR arrays, but also the targets of the CRISPR/Cas systems. Studies on functional genomics of bacteriophages have been lagging behind the discovery of new phage strains and the sequencing of their genomes...
