A practical optical trap for manipulating and isolating bacteria from complex microbial communities.

Microbial ecology

Mitchell JG, Weller R, Beconi M, Sell J, Holland J.
PMID: 24189809
Microb Ecol. 1993 Mar;25(2):113-9. doi: 10.1007/BF00177189.

A wide variety of naturally occurring bacteria cannot be isolated by classical microbiological methods, hindering study of microbial communities. To partially remove this limitation, a method using optical trapping was developed. It allows for one-step isolation of bacteria from...

Opt Lett. 2006 Jun 01;31(11):1750-2. doi: 10.1364/ol.31.001750.

Because of the stochastic nature of self-amplified spontaneous emission (SASE), it is crucial to measure for single pulses the spectral characteristics of ultrashort pulses from the vacuum ultraviolet free electron laser (FLASH) at DESY, Germany. To meet this particular...

INTRODUCTION: Psychosocial suffering involves diverse human, social and economic costs. Some 34.4% of workers in Switzerland report chronic stress related to their jobs. Medical consultations for suffering at work aim to maintain-or renew-patients' abilities to make decisions and act...

Interferometry and coherence of nonstationary light.

Optics letters

Koivurova M, Ahad L, Geloni G, Setälä T, Turunen J, Friberg AT.
PMID: 30702669
Opt Lett. 2019 Feb 01;44(3):522-525. doi: 10.1364/OL.44.000522.

We consider temporally integrating interferometric measurements and their relation to the coherence properties of nonstationary light. We find that performing such experiments as a function of time delay is equivalent to spectrally resolving the interference patterns, and time-domain coherence...

The possibility to determine electron-density distribution in crystals has been an enormous breakthrough, stimulated by a favourable combination of equipment for X-ray and neutron diffraction at low temperature, by the development of simplified, though accurate, electron-density models refined from...

Effects of energy spread on brightness and coherence of undulator sources.

Journal of synchrotron radiation

The (spectral) brightness for partially transverse coherent sources such as synchrotron radiation and free-electron laser sources can be defined as the maximum of the Wigner distribution. Then, the brightness includes information on both coherence and wavefront characteristics of the...

Friedreich's ataxia is a disease caused by a decrease in the levels of expression or loss of functionality of the mitochondrial protein frataxin (FXN). The development of an active and stable recombinant variant of FXN is important for protein...

Two-Layer Hand-Sewn Esophagojejunostomy in Totally Laparoscopic Total Gastrectomy for Gastric Cancer.

PURPOSE: Different esophagojejunostomy (EJ) reconstruction methods are used after totally laparoscopic total gastrectomy (TLTG), and none is considered a standard technique. This report describes a 2-layer hand-sewn EJ technique during TLTG; we also evaluated postoperative morbidity associated with this...
