Atheromatous plaques usually contain antigens of the periodontitis-causing bacteria Streptococcus mutans though molecular mechanism of this incorporation remains unknown. Since vascular adhesion and inflammatory potential of Immune Complexes (IC) are known we investigated the naturally occurring plasma antibodies that recognize major antigens from S. mutans. S. mutansbinding plasma proteins (SM...

The nutritional quality of Australian breakfast cereals is not systematically monitored despite the importance of breakfast for general health. We examined whether the nutritional quality of Australian breakfast cereals has improved between 2004 and 2010, and whether any change could be detected after the introduction of Daily Intake Guide (DIG) front-of-pack labelling. Supermarket surveys were...

We have studied the differences between the diffuse ionized gas (DIG) and the H ii regions along a slit position in the local dwarf irregular galaxy NGC 6822. The slit position passes through the two most prominent H ii regions: Hubble V and Hubble X. Important differences have been found in the excitation, ionization, and [N ii]λ6584Å/Hα and [S ii]λ6717Å/Hα line ratios between the DIG and the ...

Herpes simplex virus (HSV) entry requires the interaction of glycoprotein D (gD) with a cellular receptor such as herpesvirus entry mediator (HVEM or HveA) or nectin-1 (HveC). However, the fusion mechanism is still not understood. Since cholesterol-enriched cell membrane lipid rafts are involved in the entry of other enveloped viruses such as human immunodeficiency virus and Ebola virus, we tes...

The Diffuse Ionized Gas (DIG) contributes to the nebular emission of galaxies, resulting in line flux ratios that can be significantly different from those produced by HII regions. Comparing [SII]6717,31 between pointed observations regions nearby galaxies and integrated spectra more distant it has been recently claimed DIG also deeply affect bright, star-forming a large correction must applied...

Lipid rafts are regions of the plasma membrane that are enriched in cholesterol, glycosphingolipids and acylated proteins, and which have been proposed as sites for the proteolytic processing of the Alzheimer's amyloid precursor protein (APP). Lipid rafts can be isolated on the basis of their insolubility in Triton X-100 at 4 degrees C, with the resulting low-density, detergent-insoluble glycol...

BACKGROUND Front-of-pack nutrition labelling may support healthier packaged food purchases. Australia has adopted a novel Health Star Rating (HSR) system, but the legitimacy of this choice is unknown. OBJECTIVE To define the effects of different formats of front-of-pack labelling on the healthiness of food purchases and consumer perceptions. DESIGN Individuals were assigned at random to acc...

DNA mobility shift assay is widely performed to analyze sequence-specific DNA-binding proteins in cellular extracts (2), and the DNA-binding proteins can be identified by use of antibodies that induce further retardation of probes (supershift). Gel extracts from a shifted band contain not only DNA segments and DNA-binding proteins but also nonspecific proteins located at the same position in th...
