The Comprehensive Live Cell‐Based Cytotoxicity Assay for Monitoring Disease Activity and Guiding Rescue Therapy in Acute Attacks of NMOSD

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuromyelitis optica spectrum disorder (NMOSD) is a devastating neurological disease that lacks serological biomarkers that can accurately reflect disease activity. We established a live cell‐based assay (LCBA) using serum with endogenous complement to quantify the overall cytotoxicity, offering a novel functional tool for monitoring

Novel schemes for the optical manipulation of atoms and molecules [PDF]

open access: yes, 2009
The range of atoms which can be cooled by lasers is limited to those which have a closed two level structure. Several schemes have been proposed which aim to extend this range by using coherent control of the particle momenta, but none have yet been ...

Optical micromanipulation using ultrashort pulsed laser sources [PDF]

open access: yes, 2007
In this thesis two previously separate fields of study are brought together: optical micromanipulation and ultrashort laser research. Here, the benefits of combining the high peak powers of ultrashort pulsed lasers and conventional optical ...

A new laparoscope manipulator with an optical zoom [PDF]

open access: yes, 1998
This report describes a new type of laparoscope manipulator with an optical zoom. The manipulator was designed with regard to its safety in medical settings. It is based on a five-bar linkage mechanism. Back and forth movements of a laparoscope are achieved by an optical zoom.

Changes in Immune‐Inflammation Status and Prognosis in Pregnancy‐Related Cerebral Venous Thrombosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Distinguishing pathological changes from physiological adaptations in pregnancy‐related cerebral venous thrombosis (CVT) is clinically challenging. This study aimed to characterize coagulation, immune‐inflammation, and dehydration status in these patients and assess their prognostic value.

Axial plane optical microscopy for particle manipulation with Weber accelerating beams

open access: yes, 2017
We directly observe the optical particle manipulation with Weber accelerating beams by the axial plane optical microscopy (APOM). Optically trapped particles moving along parabolic trajectories are successfully monitored by the APOM. © OSA 2017.

Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]

open access: yes, 2007
The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence

Microscopic applications of holographic beam shaping and studies of optically trapped aerosols [PDF]

open access: yes, 2009
This thesis has two themes. Firstly, it concerns the original application of holographic beam shaping, employed through the methods associated with optical manipulation, to three microscopic fields of research.
