Antibiotic Resistance: What are the Opportunities for Primary Care in Alleviating the Crisis?.

Frontiers in public health

Hansen MP, Hoffmann TC, McCullough AR, van Driel ML, Del Mar CB.
PMID: 25759809
Front Public Health. 2015 Feb 24;3:35. doi: 10.3389/fpubh.2015.00035. eCollection 2015.

Numerous opportunities are available in primary care for alleviating the crisis of increasing antibiotic resistance. Preventing patients from developing an acute respiratory infection (ARI) will obviate any need for antibiotic use downstream. Hygiene measures such as physical barriers and...

Performance of a beam-multiplexing diamond crystal monochromator at the Linac Coherent Light Source.

Zhu D, Feng Y, Stoupin S, Terentyev SA, Lemke HT, Fritz DM, Chollet M, Glownia JM, Alonso-Mori R, Sikorski M, Song S, van Driel TB, Williams GJ, Messerschmidt M, Boutet S, Blank VD, Shvyd'ko YV, Robert A.
PMID: 24985798
Rev Sci Instrum. 2014 Jun;85(6):063106. doi: 10.1063/1.4880724.

A double-crystal diamond monochromator was recently implemented at the Linac Coherent Light Source. It enables splitting pulses generated by the free electron laser in the hard x-ray regime and thus allows the simultaneous operations of two instruments. Both monochromator...

Prognostic Value of Residual Disease after Interval Debulking Surgery for FIGO Stage IIIC and IV Epithelial Ovarian Cancer.

Obstetrics and gynecology international

Rutten MJ, Sonke GS, Westermann AM, van Driel WJ, Trum JW, Kenter GG, Buist MR.
PMID: 26106418
Obstet Gynecol Int. 2015;2015:464123. doi: 10.1155/2015/464123. Epub 2015 May 27.

Although complete debulking surgery for epithelial ovarian cancer (EOC) is more often achieved with interval debulking surgery (IDS) following neoadjuvant chemotherapy (NACT), randomized evidence shows no long-term survival benefit compared to complete primary debulking surgery (PDS). We performed an...

J Phys Chem Lett. 2013 Jun 06;4(11):1972-6. doi: 10.1021/jz401016h. Epub 2013 May 28.

Building a detailed understanding of the structure-function relationship is a crucial step in the optimization of molecular photocatalysts employed in water splitting schemes. The optically dark nature of their active sites usually prevents a complete mapping of the photoinduced...

PMID: 27419566
Phys Rev Lett. 2016 Jul 01;117(1):013002. doi: 10.1103/PhysRevLett.117.013002. Epub 2016 Jun 30.

We study the structural dynamics of photoexcited [Co(terpy)_{2}]^{2+} in an aqueous solution with ultrafast x-ray diffuse scattering experiments conducted at the Linac Coherent Light Source. Through direct comparisons with density functional theory calculations, our analysis shows that the photoexcitation...

Paracrine Signaling by Extracellular Vesicles via Osteoblasts.

Current molecular biology reports

Morhayim J, Rudjito R, van Leeuwen JP, van Driel M.
PMID: 27429899
Curr Mol Biol Rep. 2016;2:48-55. doi: 10.1007/s40610-016-0034-6. Epub 2016 Feb 23.

Extracellular vesicles (EVs), spherical bilayered proteolipids, behave as paracrine effectors since they are released from cells to deliver signals to other cells. They control a diverse range of biological processes by transferring proteins, lipids, and nucleic acids between cells...

Large-scale synthesis of a silicon photonic crystal with a complete three-dimensional bandgap near 1.5 micrometres.

Nature

Blanco A, Chomski E, Grabtchak S, Ibisate M, John S, Leonard SW, Lopez C, Meseguer F, Miguez H, Mondia JP, Ozin GA, Toader O, van Driel HM.
PMID: 10839534
Nature. 2000 May 25;405(6785):437-40. doi: 10.1038/35013024.

Photonic technology, using light instead of electrons as the information carrier, is increasingly replacing electronics in communication and information management systems. Microscopic light manipulation, for this purpose, is achievable through photonic bandgap materials, a special class of photonic crystals...

From coiled tubules to a secretory canaliculus: a new model for membrane transformation and acid secretion by gastric parietal cells.

Trends in cell biology

Pettitt JM, van Driel IR, Toh BH, Gleeson PA.

Trends Cell Biol. 1996 Feb;6(2):49-53. doi: 10.1016/0962-8924(96)81010-5.

The acid-secreting gastric parietal cell has a unique secretory membrane system. This membrane system exists in an inactive (non-secreting) and an active (secreting) form. The current accepted model to explain the transformation events associated with the conversion of the...

Period doubling of a femtosecond Ti:sapphire laser by total mode locking.

Optics letters

Period doubling of an 84-MHz repetition-rate Kerr-lens mode-locked Ti:sapphire laser operated at 830 nm and producing ~300mW of average power has been observed and explained in terms of total mode locking of TEM(00) and TEM(01) modes in an effective...

Measurement of the subnanosecond, nonradiative relaxation time from excited states of Nd(3+) in a Nd:YAG crystal.

We have time resolved the nonradiative relaxation from the (4)G(7/2) manifold to the upper laser level (for lambda = 1.06 microm) of Nd(3+) in a Nd:YAG crystal. This has been performed by monitoring the onset of gain for the...

Optical correlator using partial diffusers.

Young JF, van Driel HM.
PMID: 20234594
Appl Opt. 1980 Sep 15;19(18):3230-8. doi: 10.1364/AO.19.003230.

A simple real-time optical correlator based on two contacting correlated partial diffusers is described. The illumination of such diffusers by coherent light produces Young's fringes with the spacing of the fringes determined by the lateral separation of the diffusers....
