Solid-binding peptides for immobilisation of thermostable enzymes to hydrolyse biomass polysaccharides.

Biotechnology for biofuels

Care A, Petroll K, Gibson ESY, Bergquist PL, Sunna A.
PMID: 28184244
Biotechnol Biofuels. 2017 Feb 02;10:29. doi: 10.1186/s13068-017-0715-2. eCollection 2017.

BACKGROUND: Solid-binding peptides (SBPs) bind strongly to a diverse range of solid materials without the need for any chemical reactions. They have been used mainly for the functionalisation of nanomaterials but little is known about their use for the...

Diagnostic yield of endomicroscopy for dysplasia in primary sclerosing cholangitis associated inflammatory bowel disease: a feasibility study.

Endoscopy international open

Dlugosz A, Barakat AM, Björkström NK, Öst Å, Bergquist A.
PMID: 27540581
Endosc Int Open. 2016 Aug;4(8):E901-11. doi: 10.1055/s-0042-111203. Epub 2016 Aug 05.

BACKGROUND AND STUDY AIMS: Primary sclerosing cholangitis associated inflammatory bowel disease (PSC-IBD) is characterized by a high risk of colorectal dysplasia. Surveillance colonoscopies with random biopsies have doubtful power for dysplasia detection. Our aim was to prospectively investigate the...

Fear and Uncertainty Do Not Influence Reported Willingness to Undergo Lumbar Punctures in a U.S. Multi-Cultural Cohort.

Frontiers in aging neuroscience

Tsvetkova DZ, Bergquist SH, Parker MW, Jarrett TL, Howell JC, Watts KD, Kollhoff A, Roberts DL, Hu WT.
PMID: 28239349
Front Aging Neurosci. 2017 Feb 10;9:22. doi: 10.3389/fnagi.2017.00022. eCollection 2017.

Cerebrospinal fluid (CSF) biomarkers for Alzheimer's disease and related disorders can provide early and accurate prediction of underlying neuropathology even when the clinical symptoms are mild, but lumbar punctures (LP) to obtain CSF can be perceived as frightening and...

An optical clock based on a single trapped 199Hg+ ion.

Science (New York, N.Y.)

Diddams SA, Udem T, Bergquist JC, Curtis EA, Drullinger RE, Hollberg L, Itano WM, Lee WD, Oates CW, Vogel KR, Wineland DJ.
PMID: 11452082
Science. 2001 Aug 03;293(5531):825-8. doi: 10.1126/science.1061171. Epub 2001 Jul 12.

Microwave atomic clocks have been the de facto standards for precision time and frequency metrology over the past 50 years, finding widespread use in basic scientific studies, communications, and navigation. However, with its higher operating frequency, an atomic clock...

Spectroscopy using quantum logic.

Science (New York, N.Y.)

Schmidt PO, Rosenband T, Langer C, Itano WM, Bergquist JC, Wineland DJ.
PMID: 16051790
Science. 2005 Jul 29;309(5735):749-52. doi: 10.1126/science.1114375.

We present a general technique for precision spectroscopy of atoms that lack suitable transitions for efficient laser cooling, internal state preparation, and detection. In our implementation with trapped atomic ions, an auxiliary "logic" ion provides sympathetic laser cooling, state...

Femtosecond-laser-based synthesis of ultrastable microwave signals from optical frequency references.

Optics letters

Bartels A, Diddams SA, Oates CW, Wilpers G, Bergquist JC, Oskay WH, Hollberg L.
PMID: 15792011
Opt Lett. 2005 Mar 15;30(6):667-9. doi: 10.1364/ol.30.000667.

We use femtosecond laser frequency combs to convert optical frequency references to the microwave domain, where we demonstrate the synthesis of 10-GHz signals having a fractional frequency instability of < or =3.5 x 10(-15) at a 1-s averaging time,...

The cellular localization of long chain fatty acids in sponges.

Tissue & cell

Lawson MP, Bergquist PR, Cambie RC.
PMID: 18620155
Tissue Cell. 1986;18(1):19-26. doi: 10.1016/0040-8166(86)90004-2.

Examination of fractionated sponge tissue shows that long chain fatty acids (LCFAs) occur in high proportions in cell membranes. This conclusion refutes a recent suggestion made by other workers that sponge membranes would contain conventional fatty acids similar to...

Generation of continuous-wave 194-nm radiation by sum-frequency mixing in an external ring cavity.

Optics letters

Hemmati H, Bergquist JC, Itano WM.
PMID: 19714140
Opt Lett. 1983 Feb 01;8(2):73-5. doi: 10.1364/ol.8.000073.

Several microwatts of tunable cw radiation near 194 nm in a linewidth of less than 2 MHz have been generated by sum-frequency mixing the radiation from a frequency-doubled argon-ion laser with the radiation from a ring dye laser in...

Symmetry of [N-X-N]+ halogen bonds in solution.

Chemical communications (Cambridge, England)

Carlsson AC, Gräfenstein J, Laurila JL, Bergquist J, Erdélyi M.
PMID: 22011957

The first investigation of halogen bond symmetry is presented. In contrast to related hydrogen bonds, the iodous halogen bond is symmetric in solution and in the crystal. The bromous analogue is symmetric in solution, but shows asymmetry in the...

PMID: 24525944
NeuroRehabilitation. 1997;8(1):49-56. doi: 10.3233/NRE-1997-8107.

Psychology has a primary role in cognitive rehabilitation along with other disciplines, but may be best qualified for evaluating specific cognitive abilities directing, cognitive-behavioral intervention programs, and measuring outcomes. Several specialties within psychology provide cognitive rehabilitation services; however, current...
