The bifurcation point of the oxygen reduction reaction on Au-Pd nanoalloys.

Faraday discussions

Staszak-Jirkovský J, Ahlberg E, Panas I, Schiffrin DJ.
PMID: 27089504
Faraday Discuss. 2016 Jul 04;188:257-78. doi: 10.1039/c5fd00233h.

The oxygen reduction reaction is of major importance in energy conversion and storage. Controlling electrocatalytic activity and its selectivity remains a challenge of modern electrochemistry. Here, first principles calculations and analysis of experimental data unravel the mechanism of this...

Lateral opening in the intact β-barrel assembly machinery captured by cryo-EM.

Nature communications

Iadanza MG, Higgins AJ, Schiffrin B, Calabrese AN, Brockwell DJ, Ashcroft AE, Radford SE, Ranson NA.
PMID: 27686148
Nat Commun. 2016 Sep 30;7:12865. doi: 10.1038/ncomms12865.

The β-barrel assembly machinery (BAM) is a ∼203 kDa complex of five proteins (BamA-E), which is essential for viability in E. coli. BAM promotes the folding and insertion of β-barrel proteins into the outer membrane via a poorly understood...

Precision control of single-molecule electrical junctions.

Nature materials

Haiss W, Wang C, Grace I, Batsanov AS, Schiffrin DJ, Higgins SJ, Bryce MR, Lambert CJ, Nichols RJ.
PMID: 17128259
Nat Mater. 2006 Dec;5(12):995-1002. doi: 10.1038/nmat1781. Epub 2006 Nov 26.

There is much discussion of molecules as components for future electronic devices. However, the contacts, the local environment and the temperature can all affect their electrical properties. This sensitivity, particularly at the single-molecule level, may limit the use of...

Integrated-optical directional coupler biosensor.

Optics letters

Luff BJ, Harris RD, Wilkinson JS, Wilson R, Schiffrin DJ.
PMID: 19876102
Opt Lett. 1996 Apr 15;21(8):618-20. doi: 10.1364/ol.21.000618.

We present measurements of biomolecular binding reactions, using a new type of integrated-optical biosensor based on a planar directional coupler structure. The device is fabricated by Ag(+) - Na(+) ion exchange in glass, and definition of the sensing region...

Structure and dielectric properties of electrochemically grown ZrO2 films.

Acta chimica Slovenica

Gomez-Sanchez A, Katunar M, Schreiner W, Duffó G, Ceré S, Schiffrin DJ.
PMID: 25125115
Acta Chim Slov. 2014;61(2):316-27.

The dielectric properties of electrochemically grown zirconium oxide films by anodisation of zirconium in 1.0 mol dm-3 phosphoric acid solution were investigated in a 3 to 30 V potential range with a view to inducing surface modifications for eventual...

Increased blood pressure, vascular inflammation, and endothelial dysfunction in androgen-deficient follitropin receptor knockout male mice.

Journal of the American Society of Hypertension : JASH

Javeshghani D, Sairam MR, Schiffrin EL, Touyz RM.
PMID: 20409866
J Am Soc Hypertens. 2007 Sep-Oct;1(5):353-61. doi: 10.1016/j.jash.2007.06.003.

The relationship between testosterone, vascular function, and blood pressure remains unclear. Here we utilized a mouse model of andropause, follitropin receptor knockout (FORKO) male mice, which are testosterone-deficient, to investigate whether vascular function and structure are altered and whether...

Potentiation of vascular oxidative stress and nitric oxide-mediated endothelial dysfunction by high-fat diet in a mouse model of estrogen deficiency and hyperandrogenemia.

Journal of the American Society of Hypertension : JASH

Javeshghani D, Schiffrin EL, Sairam MR, Touyz RM.
PMID: 20409973
J Am Soc Hypertens. 2009 Sep-Oct;3(5):295-305. doi: 10.1016/j.jash.2009.07.002.

Estrogen deficiency is associated with increased cardiovascular risk due, in part, to hypertension, endothelial dysfunction, obesity, and hypercholesterolemia. Underlying mechanisms for this remain unclear. Here, we investigated whether high-fat intake aggravates vascular dysfunction through oxidative stress and inflammation, which...

Measurement of intracellular free calcium ion concentration in vascular smooth muscle cells : fluorescence imaging of cytosolic calcium.

Methods in molecular medicine

Touyz RM, Schiffrin EL.
PMID: 21331728
Methods Mol Med. 2001;51:341-54. doi: 10.1385/1-59259-087-X:341.

Changes in intracellular free calcium ion concentration ([Ca(2+)](i)) play a major role in vascular smooth muscle cell function (1,2). Elevation of [Ca(2+)](i) is an important regulator of multiple downstream signaling pathways and it is a major determinant of vascular...

Renal denervation therapy for resistant hypertension.

Current treatment options in cardiovascular medicine

Davis M, Schiffrin EL, Joyal D.

OPINION STATEMENT: Hypertension is common and leads to significant cardiovascular morbidity and mortality. Some patients are unable to achieve target blood pressures despite multiple antihypertensive medications; these patients are labeled as having resistant hypertension. To palliate the lack of...
