Top medicine articles for April 2014

A collection of some interesting medical articles published recently:Vitamin D supplements are taken by nearly half of American adults. Low levels of vitamin D are a result, not a cause, of poor health. Therefore, supplement may not help http://buff.ly/Ml153n -- Vitamin D supplement sales increased more than 10-fold, from $24 million in 2002 to $605 million in 2011 (US data) http://buff.ly/Mo7Ykj"Is Your Stethoscope Going to Join Typewriter in the Storage Closet?" http://buff.ly/1dILsbh - However, you can't listen to lungs with ultrasound.Coffee Hydrates as Well as Water http://buff.ly/1i5Rc3V - Study defined moderate intake of coffee as 4 cups per day.Caramel color: The health risk that may be in your soda (no real caramel there, it's 4-MeI). Artificial caramel coloring contains a potentially carcinogenic chemical called 4-methylimidazole (4-MeI). Caramel color is the single most used food coloring in the world http://buff.ly/1fmZwfnOlder adults with impaired hearing may have a faster rate of "brain shrinkage" as they age http://buff.ly/1fdxRwIFor preventing colds, frequent hand washing came out on top (review study) http://buff.ly/1fmZLadWhole Foods Bans Produce Grown With Sludge made from municipal waste and feces/urine "biosolids" http://buff.ly/1dUhNQKStudy: Children's Vitamins Contain Far More Than Recommended Amounts (except vitamin D) http://buff.ly/1fdyw1eAdrenal "Incidentalomas" May Increase Cardiovascular Risk http://buff.ly/...

Ehsan RoozmehAbstractIn this paper, we study magnetic and structural properties of silver and gold-coated iron nanoparticle as novel drug delivery systems for the two commercially famous cancer treatment drugs, using the density functional theory (DFT) computations.Our calculations show that silver and gold-coated iron nanoparticle have magnetization and the magnetic moment of the Fe atom in the Fe@(Ag/Au)n core-shells saturated to a value of about 3 μB. Thus...

Publication date: Available online 21 March 2019Source: Carbohydrate PolymersAuthor(s): Shuo Tang, Ting Wang, Caoxing Huang, Chenhuan Lai, Yimin Fan, Qiang YongAbstractA highly branched arabinogalactan isolated from Larix principis-rupprechtii and subjected to sulfation derivatization to promote their antitumor bioactivity. Several structural features of the sulfated arabinogalactans (S-LAG) were investigated: molecular weight, monosaccharide constitution, and chemical structures. Spectral analysis indicated that sulfate groups were successfully introduced on arabinogalactan. Sulfated products showed different degrees of s...

However, the exact relationship between VDR and IDD remains unknown. The aim of this study was to investigate the age-dependent expression of VDR in rat intervertebral discs and to determine ...

Publication date: Available online 21 March 2019Source: The Journal of Supercritical FluidsAuthor(s): Diego Márlon Ferro, Simone Mazzutti, Luciano Vitali, Carmen Maria Oliveira Müller, Sandra Regina Salvador FerreiraAbstractIntegrated downstream processes, combining Supercritical Fluid Extraction (SFE) with Pressurized Liquid Extraction (PLE), were used to recover antioxidants from Sida rhombifolia leaves. The SFE depressurization step was evaluated to improve PLE efficiency in the recovery of phenolic compounds. Total phenolic content of the extracts was performed by Folin-Ciocalteu method, and in vitro antiox...

Publication date: Available online 21 March 2019Source: Journal of Solid State ChemistryAuthor(s): Zhang Hao, Li Lei, Wenbin WangAbstractNucleation and growth of ettringite in solution with and without temperature rising inhibitor (TRI) were investigated. Electrical conductivity, X-ray diffraction, scanning electron microcopy, optical microcopy and Fourier transform infrared were used to analyze the mechanism of effects of TRI on nucleation and growth of ettringite. Based on classical nucleation theory, the results show that TRI has little influence on the crystal-solution interfacial energy. In contrast, the inhibition of...
