Antibacterial properties of composite resins incorporating silver and zinc oxide nanoparticles on Streptococcus mutans and Lactobacillus.

Restorative dentistry & endodontics

Kasraei S, Sami L, Hendi S, Alikhani MY, Rezaei-Soufi L, Khamverdi Z.
PMID: 24790923
Restor Dent Endod. 2014 May;39(2):109-14. doi: 10.5395/rde.2014.39.2.109. Epub 2014 Mar 21.

OBJECTIVES: Recurrent caries was partly ascribed to lack of antibacterial properties in composite resin. Silver and zinc nanoparticles are considered to be broad-spectrum antibacterial agents. The aim of the present study was to evaluate the antibacterial properties of composite...

Biocompatible dispersion methods for carbon black.

Toxicological research

Kim H, Park K, Lee MY.
PMID: 24278612
Toxicol Res. 2012 Dec;28(4):209-16. doi: 10.5487/TR.2012.28.4.209.

The biological activity of particles is largely dependent on their size in biological systems. Dispersion in the aqueous phase has been both a critical impediment to and a prerequisite for particle studies. Carbon black has been used as a...

Effects of Cyclooxygenase and Lipoxygenase Inhibitors on the Proliferation of Colon Cancer Cells and Their Production of Eicosanoids.

Cancer research and treatment

Lee HS, Kim EJ, Oh YS, Cho HJ, Park JH.
PMID: 26680815
Cancer Res Treat. 2001 Oct;33(5):404-13. doi: 10.4143/crt.2001.33.5.404.

PURPOSE: Epidemiological and laboratory studies suggest that nonsteroidal antiinflammatory drugs (NSAIDs) reduce the risk of colon cancer and that the inhibition of colon cancer is mediated through modulation of eicosanoid production. The present study examined the effect of cyclooxygenase...

Metformin Promotes Apoptosis but Suppresses Autophagy in Glucose-Deprived H4IIE Hepatocellular Carcinoma Cells.

Diabetes & metabolism journal

Park DB.
PMID: 26706918
Diabetes Metab J. 2015 Dec;39(6):518-27. doi: 10.4093/dmj.2015.39.6.518.

BACKGROUND: Metformin, a well-known anti-diabetic drug, has gained interest due to its association with the reduction of the prevalence of cancer in patients with type 2 diabetes and the anti-proliferative effect of metformin in several cancer cells. Here, we...

The trophic effect of gaba on cerebellar granule cells is mediated by gaba-receptors.

International journal of developmental neuroscience : the official journal of the International Society for Developmental Neuroscience

Meier E, Hansen GH, Schousboe A.
PMID: 24874866
Int J Dev Neurosci. 1985;3(4):401-7. doi: 10.1016/0736-5748(85)90074-7.

The effect of GABA, its agonist THIP (4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol), and its antagonist bicuculline methobromide on the ultrastructure of cerebellar granule cells was studied. It was found that while the density of mitochondria, the ribosomes and smooth endoplasmic reticulum was unaffected...

Exfoliation of graphite with triazine derivatives under ball-milling conditions: preparation of few-layer graphene via selective noncovalent interactions.

ACS nano

León V, Rodriguez AM, Prieto P, Prato M, Vázquez E.
PMID: 24380430
ACS Nano. 2014 Jan 28;8(1):563-71. doi: 10.1021/nn405148t. Epub 2014 Jan 13.

A ball-milling treatment can be employed to exfoliate graphite through interactions with commercially available melamine under solid conditions. This procedure allows the fast production of relatively large quantities of material with a low presence of defects. The milling treatment...

Effect of Tissue-Culture Substratum and Extracellular Matrix Overlay on Liver-Selective and Xenobiotic Inducible Gene Expression in Primary Rat Hepatocytes.

In vitro toxicology

Sidhu JS, Farin FM, Kavanagh TJ, Omiecinski CJ.
PMID: 24817786
In Vitro Toxicol. 1994;7(3):225-242.

In a previous study (Sidhu et al., 1993), we demonstrated that a combination of certain cell culture media, hormone addition, and extracellular matrix (ECM) overlay coordinately modulated the expression of certain liver-selective genes in primary rat hepatocyte cultures, including...

Antimicrobial susceptibilities of Escherichia coli isolates as agents of community-acquired urinary tract infection (2008-2014).

Turkish journal of urology

Yılmaz N, Ağuş N, Bayram A, Şamlıoğlu P, Şirin MC, Derici YK, Hancı SY.
PMID: 27011879
Turk J Urol. 2016 Mar;42(1):32-6. doi: 10.5152/tud.2016.90836.

OBJECTIVE: Urinary tract infections (UTIs) are among the most frequently seen community-acquired infections worldwide. E. coli causes 90% of urinary system infections. To guide the empirical therapy, the resistance pattern of E. coli responsible for community-acquired UTI was evaluated...

Biodiesel production potential of mixed microalgal culture grown in domestic wastewater.

Bioprocess and biosystems engineering

Soydemir G, Keris-Sen UD, Sen U, Gurol MD.
PMID: 26481921
Bioprocess Biosyst Eng. 2016 Jan;39(1):45-51. doi: 10.1007/s00449-015-1487-3.

In this study, a mixed microalgal culture grown in secondarily treated domestic wastewater effluent was investigated for biodiesel production using in situ transesterification method with conventional heating. The total lipid content of the mixed culture was found as 26.2%...

Data on isolating mesenchymal stromal cells from human adipose tissue using a collagenase-free method.

Data in brief

Shebaby W, Abdalla EK, Saad F, Faour WH.
PMID: 26949729
Data Brief. 2016 Feb 08;6:974-9. doi: 10.1016/j.dib.2016.02.002. eCollection 2016 Mar.

The present dataset describes a detailed protocol to isolate mesenchymal cells from human fat without the use of collagenase. Human fat specimen, surgically cleaned from non-fat tissues (e.g., blood vessels) and reduced into smaller fat pieces of around 1-3...

Development of cytoskeletal connections between cells of preimplantation mouse embryos.

Roux's archives of developmental biology : the official organ of the EDBO

Mayor R, Pey R, Izquierdo L.
PMID: 28305487
Rouxs Arch Dev Biol. 1989 Nov;198(4):233-241. doi: 10.1007/BF00375910.

Observations by scanning electron microscopy of mouse cleaving embryos reveal the presence of long microvilli around cell contact regions that often bridge the gap between blastomeres. These microvilli correspond, in detergent-extracted morulae, to strings connecting the cortical cytoskeletons of...

Thromboxane A2 Receptor Stimulation Enhances Microglial Interleukin-1β and NO Biosynthesis Mediated by the Activation of ERK Pathway.

Frontiers in aging neuroscience

Yang W, Yan A, Zhang T, Shao J, Liu T, Yang X, Xia W, Fu Y.
