Background The affinity research group (ARG) model is a set of practices built on a cooperative team framework to support the creation and maintenance of dynamic and inclusive research groups in which students learn and apply the knowledge and skills required for research and cooperative work. Using situated learning theory, we conducted a qualitative study of current and former ARG members to ...

Antimicrobials are widely used, not only for treating human infections, but also for treatment of livestock and in fish farms. Human habitats in Southeastern Asian countries are located in close proximity to aquatic environments. As such, the human populations within these regions are at risk of exposure to antimicrobial resistant bacteria, and thereby disseminating antimicrobial resistance gen...

The gene coding for Escherichia coli arginyl-tRNA synthetase (argS) was isolated as a fragment of 2.4 kb after analysis and subcloning of recombinant plasmids from the Clarke and Carbon library. The clone bearing the gene overproduces arginyl-tRNA synthetase by a factor 100. This means that the enzyme represents more than 20% of the cellular total protein content. Sequencing revealed that the f...

Abstract Background Dysregulation of the balance between proliferation and apoptosis is basis for human hepatocarcinogenesis. In many malignant tumors, such as hepatocellular carcinoma (HCC), there a correlation apoptotic dysregulation poor prognosis. However, prognostic values apoptosis-related genes (ARGs) in HCC have not been elucidated. Methods To screen differentially expressed ARGs, expre...

An aquarium ecosystem is home to many animal species providing conditions similar to native aquatic habitats but under highly controlled management. With a growing interest in understanding the interaction of microbiomes and resident animal health within aquarium environments, we undertook a metagenomic survey of viromes in seven aquarium systems with differing physicochemical and resident anim...

Currency is possibly one of the main media transmitting pathogens and drug resistance due to its wide circulation in daily life. In this study, we made a comprehensive characterization of the bacterial community present on banknotes collected from different geographical regions of Hong Kong (HK) by performing in vitro characterization of the bacterial presence and resistome profile, as well as ...

In this paper, an original scheme for video similarity detection is proposed in order to establish correspondence between two video sequences. This scheme consists first to summarize the visual contents of a video sequence in a small set of images. Each image is then modeled, by an Attributed Relational Graph (ARG), as the composition of salient objects with specific spatial relationship. Match...

This study compared three different disinfection processes (chlorination, E-beam, and ozone) and the efficacy of three oxidants (H2O2, S2O(-)8, and peroxymonosulfate (MPS)) in removing antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in a synthetic wastewater. More than 30 mg/L of chlorine was needed to remove over 90% of ARB and ARG. For the E-beam method, only 1 dose...

Inexact graph matching has been widely investigated to relate a set of object/scene primitives extracted from an image to a set of counterparts representing a model or reference. However, little has been done to address how to build such a model or reference. This paper develops the theory for automatic contextual pattern modelling to automatically learn a parametric pattern ARG model from mult...
