Group-ICA Model Order Highlights Patterns of Functional Brain Connectivity.

Frontiers in systems neuroscience

Abou Elseoud A, Littow H, Remes J, Starck T, Nikkinen J, Nissilä J, Timonen M, Tervonen O, Kiviniemi V.
PMID: 21687724
Front Syst Neurosci. 2011 Jun 03;5:37. doi: 10.3389/fnsys.2011.00037. eCollection 2011.

Resting-state networks (RSNs) can be reliably and reproducibly detected using independent component analysis (ICA) at both individual subject and group levels. Altering ICA dimensionality (model order) estimation can have a significant impact on the spatial characteristics of the RSNs...

GroupICA dual regression analysis of resting state networks in a behavioral variant of frontotemporal dementia.

Frontiers in human neuroscience

Rytty R, Nikkinen J, Paavola L, Abou Elseoud A, Moilanen V, Visuri A, Tervonen O, Renton AE, Traynor BJ, Kiviniemi V, Remes AM.
PMID: 23986673
Front Hum Neurosci. 2013 Aug 26;7:461. doi: 10.3389/fnhum.2013.00461. eCollection 2013.

Functional MRI studies have revealed changes in default-mode and salience networks in neurodegenerative dementias, especially in Alzheimer's disease (AD). The purpose of this study was to analyze the whole brain cortex resting state networks (RSNs) in patients with behavioral...

Water purification ultrafiltration membranes using nanofibers from unbleached and bleached rice straw.

Scientific reports

Hassan ML, Fadel SM, Abouzeid RE, Abou Elseoud WS, Hassan EA, Berglund L, Oksman K.
PMID: 32647119
Sci Rep. 2020 Jul 09;10(1):11278. doi: 10.1038/s41598-020-67909-3.

There has been an increasing interest in recent years in isolating cellulose nanofibers from unbleached cellulose pulps for economic, environmental, and functional reasons. In the current work, cellulose nanofibers isolated from high-lignin unbleached neutral sulfite pulp were compared to...

CMC is more than a measure of corticospinal tract integrity in acute stroke patients.

NeuroImage. Clinical

Aikio R, Laaksonen K, Sairanen V, Parkkonen E, Abou Elseoud A, Kujala J, Forss N.
PMID: 34555801
Neuroimage Clin. 2021;32:102818. doi: 10.1016/j.nicl.2021.102818. Epub 2021 Sep 02.

In healthy subjects, motor cortex activity and electromyographic (EMG) signals from contracting contralateral muscle show coherence in the beta (15-30 Hz) range. Corticomuscular coherence (CMC) is considered a sign of functional coupling between muscle and brain. Based on prior...

The additional utility of two-dimensional strain in detection of coronary artery disease presence and localization in patients undergoing dobutamine stress echocardiogram.

Echocardiography (Mount Kisco, N.Y.)

Roushdy A, Abou El Seoud Y, Abd Elrahman M, Wadeaa B, Eletriby A, Abd El Salam Z.
PMID: 28548371
Echocardiography. 2017 Jul;34(7):1010-1019. doi: 10.1111/echo.13569. Epub 2017 May 26.

BACKGROUND: Dobutamine stress echocardiogram (DSE) is a feasible and safe exercise-independent stress modality for diagnoses of coronary artery disease (CAD), but it is subjective, and operator dependant. Two-dimensional strain at peak stress could overcome these limitations and thus increase...

The Effect of Gray Matter ICA and Coefficient of Variation Mapping of BOLD Data on the Detection of Functional Connectivity Changes in Alzheimer's Disease and bvFTD.

Frontiers in human neuroscience

Tuovinen T, Rytty R, Moilanen V, Abou Elseoud A, Veijola J, Remes AM, Kiviniemi VJ.
PMID: 28119587
Front Hum Neurosci. 2017 Jan 09;10:680. doi: 10.3389/fnhum.2016.00680. eCollection 2016.

Resting-state fMRI results in neurodegenerative diseases have been somewhat conflicting. This may be due to complex partial volume effects of CSF in BOLD signal in patients with brain atrophy. To encounter this problem, we used a coefficient of variation...

Nanocomposite Film Based on Cellulose Acetate and Lignin-Rich Rice Straw Nanofibers.

Materials (Basel, Switzerland)

Hassan M, Berglund L, Abou-Zeid R, Hassan E, Abou-Elseoud W, Oksman K.
PMID: 30781531
Materials (Basel). 2019 Feb 16;12(4). doi: 10.3390/ma12040595.

Nanofibers isolated from unbleached neutral sulfite rice straw pulp were used to prepare transparent films without the need to modify the isolated rice straw nanofibers (RSNF). RSNF with loading from 1.25 to 10 wt.% were mixed with cellulose acetate...
