The Transmission Confocal Laser Scanning Microscope [PDF]

open access: yesMicroscopy Today, 1992
Abstract A confocal laser scanning microscope which can collect images in both transmission and reflection modes has been installed and is being tested in the Imaging Laboratories of the John P. Roberts Research Institute, London, Ontario. Designed by Dr.

Microscopic Spectrophotometry Using Confocal Laser Scanning Microscope

open access: yesBUNSEKI KAGAKU, 2008
共焦点レーザー走査型顕微鏡(CLSM)を用いた顕微吸光度分析の精度及び適応範囲などを検証するために,粒径が50及び150 μmの2種類の球状シリカゲルにジヒドロオキソ(テトラフェニルポルフィリナト)アンチモン臭化物錯体(1)を0.70~3.59 mmol dm-3のモル濃度(C1m)で吸着させてマイクロビーズ(2)を調製した.CLSMでの試料の測定領域は,対物レンズの倍率及びピンホールの直径又はファイバーコアの直径によって決められる直径が2.14 μmの円形内であることが分かった.更に分析範囲,測定範囲などの分析条件を検討した結果,4.9~350 μmの球状試料について測定波長が488~775 nmで分析可能であることが分かった.そこで ...

Enhanced scanning control in a confocal scanning laser microscope [PDF]

open access: yesScanning, 1996
AbstractA fast and flexible scanning unit, allowing scanning rates of more than 1 kHz over regions identified in a specimen, has been developed and evaluated. This scanning unit replaces the original scanning unit in the Phoibos confocal scanning laser microscope and features full backward compatibility, while at the same time allowing fast and ...

The Laser-Scanning Confocal Microscope in Biomedical Research

open access: yesExperimental Biology and Medicine, 1991
The laser-scanning confocal microscope (LSCM) produces improved light microscope images of both fixed and living cells and tissues. Moreover, the serial optical-sectioning power of the LSCM has made three dimensional reconstruction of light microscope images a practical option.

An optical spectrometer for a confocal scanning laser microscope [PDF]

open access: yesScanning, 1995
AbstractAn optical spectrometer for the visible range has been developed for the confocal scanning laser microscope (CSLM) Phoibos 1000. The spectrometer records information from a single point or a user‐defined region within the microscope specimen. A prism disperses the spectral components of the recorded light over a linear CCD photodiode array with

Evaluating the efficacy of Vibrospiral novel sealer placing instrument: a Confocal and Scanning Electron Microscope in-vitro study

open access: yesBMC Oral Health
Background An endodontic sealer forms an interface between gutta-percha and root canal walls. Ideally, the sealer layer should be void-free, thin, uniform, well-adapted to the dentinal walls, and exhibit good tubular penetration, which contributes to a ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells
