The importance of sports performance factors and training contents from the perspective of futsal coaches.

Journal of human kinetics

Serrano J, Shahidian S, Sampaio J, Leite N.
PMID: 24235991
J Hum Kinet. 2013 Oct 08;38:151-60. doi: 10.2478/hukin-2013-0055. eCollection 2013.

The aim of this study was to identify the importance assigned by futsal coaches with different education levels to the sports performance factors (technical, tactical, physical and psychological) and to the training contents. The sample was divided into three...

Release of growth factors after mechanical and chemical pleurodesis for treatment of malignant pleural effusion: a randomized control study.

Radiology and oncology

Hojski A, Leitgeb M, Crnjac A.
PMID: 26834526
Radiol Oncol. 2015 Nov 27;49(4):386-94. doi: 10.1515/raon-2015-0002. eCollection 2015 Dec.

BACKGROUND: Growth factors are key inducers of fibrosis but can also mediate inflammatory responses resulting in increasing pleural effusion and acute respiratory distress syndrome. The primary aim of the study was to analyse growth factors release after performing chemical...

Involvement of atypical protein kinase C in the regulation of cardiac glucose and long-chain fatty acid uptake.

Frontiers in physiology

Habets DD, Luiken JJ, Ouwens M, Coumans WA, Vergouwe M, Maarbjerg SJ, Leitges M, Bonen A, Richter EA, Glatz JF.
PMID: 22973240
Front Physiol. 2012 Sep 11;3:361. doi: 10.3389/fphys.2012.00361. eCollection 2012.

AIM: The signaling pathways involved in the regulation of cardiac GLUT4 translocation/glucose uptake and CD36 translocation/long-chain fatty acid uptake are not fully understood. We compared in heart/muscle-specific PKC-λ knockout mice the roles of atypical PKCs (PKC-ζ and PKC-λ) in...

Spectral measurement of absorption by spectroscopic frequency-domain optical coherence tomography.

Optics letters

Leitgeb R, Wojtkowski M, Kowalczyk A, Hitzenberger CK, Sticker M, Fercher AF.
PMID: 18064195
Opt Lett. 2000 Jun 01;25(11):820-2. doi: 10.1364/ol.25.000820.

A new method of measurement that essentially combines Fourier-domain optical coherence tomography with spectroscopy is introduced. By use of a windowed Fourier transform it is possible to obtain, in addition to the object structure, spectroscopic information such as the...

Full range complex spectral optical coherence tomography technique in eye imaging.

Optics letters

Wojtkowski M, Kowalczyk A, Leitgeb R, Fercher AF.
PMID: 18026464
Opt Lett. 2002 Aug 15;27(16):1415-7. doi: 10.1364/ol.27.001415.

We demonstrate a new implementation of complex spectral optical coherence tomography (OCT) in biomedical imaging. By reconstruction of both amplitude and phase we are able to use the negative and positive optical path differences to get images of objects...

Complex ambiguity-free Fourier domain optical coherence tomography through transverse scanning.

Optics letters

PMID: 18059964
Opt Lett. 2007 Dec 01;32(23):3453-5. doi: 10.1364/ol.32.003453.

We introduce a simple and cheap method for phase-shifting Fourier domain optical coherence tomography (FDOCT) that does not need additional devices and can easily be implemented. A small beam offset at the fast beam-scanning mirror introduces a causal phase...

Opt Express. 2004 Nov 29;12(24):5940-51. doi: 10.1364/opex.12.005940.

Recently, we developed a phase resolved polarization sensitive OCT system based on transversal scanning. This system was now improved and adapted for retinal imaging in vivo. We accelerated the image acquisition speed by a factor of 10 and adapted...

Bilenca A, Lasser T, Ozcan A, Leitgeb RA, Bouma BE, Tearney GJ.
PMID: 19532519
Opt Express. 2007 Mar 19;15(6):2810-21. doi: 10.1364/oe.15.002810.

Recently, we have experimentally demonstrated a new form of cross-sectional, coherence-gated fluorescence imaging referred to as SD-FCT ('spectral-domain fluorescence coherence tomography'). Imaging in SD-FCT is accomplished by spectrally detecting self-interference of the spontaneous emission of fluorophores, thereby providing depth-resolved...
