Glycan-binding protein (GBP) interaction experiments, such as glycan microarrays, are often used to understand glycan recognition patterns. However, oftentimes the interpretation of glycan array experimental data makes it difficult to identify discrete GBP binding patterns due to their ambiguity. It is known that lectins, for example, are non-specific in their binding affinities; the same lectin can bind to different monosaccharides or even different glycan structures. In bioinformatics, several tools to mine the data generated from these sorts of experiments have been developed...

Adrenaline and noradrenaline bind to membrane receptors of the superfamily of G protein-coupled receptors (GPCR) in target cells, where they modulate physiological responses such as metabolism, vasoconstriction, vasodilation and proliferation. Alteration in their function is associated with conditions such as hypertension, benign prostatic hyperplasia and cardiac hypertrophy. In response to adrenaline, receptors form signaling complexes, which enables adrenergic action to be specific, rapid and efficient. These signaling complexes or signalosomes are composed of kinases, phosphatases, and adapter and scaffold proteins, which together modulate the receptor function...

Muscular dystrophy is a disease characterized by progressive muscle weakness and degeneration. There are currently no available treatments for most muscular diseases, such as muscular dystrophy. Moreover, current therapeutics are focused on improving the quality of life of patients by relieving the symptoms or stress caused by the disease. Although the causative genes for many muscular diseases have been identified, the mechanisms underlying their pathogenesis remain unclear. Patient-derived induced pluripotent stem cells (iPSCs) have become a powerful tool for understanding the pathogenesis of intractable diseases, as well as for phenotype screening, which can serve as the basis for developing new drugs...

Interest in the common marmoset (Callithrix jacchus) as a primate model animal has grown recently, in part due to the successful demonstration of transgenic marmosets. However, there is some debate as to the suitability of marmosets, compared to more widely used animal models, such as the macaque monkey and mouse. Especially, the usage of marmoset for animal models of human cognition and mental disorders, is still yet to be fully explored. To examine the prospects of the marmoset model for neuroscience research, the Marmoset Gene Atlas (https://gene-atlas...

Neural tube defects (NTDs) occur secondary to failed closure of the neural tube between the third and fourth weeks of gestation. The worldwide incidence ranges from 0.3 to 200 per 10,000 births with the United States of American NTD incidence at around 3-6.3 per 10,000 dependent on race and socioeconomic background. Human NTD incidence has fallen by 35-50% in North America due to mandatory folic acid fortification of enriched cereal grain products since 1998. The US Food and Drug Administration has approved the folic acid fortification of corn masa flour with the goal to further reduce the incidence of NTDs, especially among individuals who are Hispanic...

Elderly pneumonia patients have various underlying diseases and social backgrounds, and it is difficult to predict their mortality using the current severity assessment tools. However, aspiration is a risk factor for mortality in pneumonia patients. In the evaluation of aspiration, endoscopic and video fluoroscopic methods are reliable but cannot be performed in all pneumonia patients. We evaluated the significance of the Mann Assessment of Swallowing Ability (MASA) in these patients. This study was prospectively performed between December 2014 and June 2015, and all adult hospitalized patients with pneumonia were consecutively enrolled...

BACKGROUND: In a healthy individual, ammonia is converted to urea in the liver. Urea is then transported through the bloodstream and then excreted into the urine by the kidneys. In patients with chronic kidney disease (CKD), the accumulated urea is degraded by salivary urease into ammonia, which is then excreted by breathing. Breath ammonia can therefore be used for detecting the increased nitrogen-bearing wastes. In our pilot study, an electrochemical sensor was used to measure and analyze breath ammonia in healthy volunteers and patients with CKD...

OBJECTIVES: Carotid intima-media thickness (cIMT) may be used increasingly as a cardiovascular disease (CVD) screening tool in individuals with spinal cord injury (SCI) as other routine invasive diagnostic tests are often unfeasible. However, variation in cIMT acquisition and analysis methods is an issue in the current published literature. The growth of the field is dependent on cIMT quality acquisition and analysis to ensure accurate reporting of CVD risk. The purpose of this study is to evaluate the quality of the reported methodology used to collect cIMT values in SCI...

Motivation: A glycan consists of monosaccharides linked by glycosidic bonds, has branches and forms complex molecular structures. Databases have been developed to store large amounts of glycan-binding experiments, including glycan arrays with glycan-binding proteins. However, there are few bioinformatics techniques to analyze large amounts of data for glycans because there are few tools that can handle the complexity of glycan structures. Thus, we have developed the MCAW (Multiple Carbohydrate Alignment with Weights) tool that can align multiple glycan structures, to aid in the understanding of their function as binding recognition molecules...

Fluorophores with emission wavelengths that shift depending on their hydrogen-bonding microenvironment in water would be fascinating tools for the study of biological events. Herein we describe the design and synthesis of a series of water-soluble solvatochromic fluorophores, 2,5-bis(oligoethylene glycol)oxybenzaldehydes (8-11) and 2,5-bis(oligoethylene glycol)oxy-1,4-dibenzaldehydes (14-17), based on a push-pull strategy. Unlike typical examples in this class of fluorophores, the fluorescence properties of these compounds are independent of solvent polarity and become fluorescent upon intermolecular hydrogen-bonding, exhibiting high quantum yields (up to ϕ = 0...
