A comparison of two sleep spindle detection methods based on all night averages: individually adjusted vs. fixed frequencies.

Frontiers in human neuroscience

Ujma PP, Gombos F, Genzel L, Konrad BN, Simor P, Steiger A, Dresler M, Bódizs R.
PMID: 25741264
Front Hum Neurosci. 2015 Feb 17;9:52. doi: 10.3389/fnhum.2015.00052. eCollection 2015.

Sleep spindles are frequently studied for their relationship with state and trait cognitive variables, and they are thought to play an important role in sleep-related memory consolidation. Due to their frequent occurrence in NREM sleep, the detection of sleep...

The reliability of ultrasonography in developmental dysplasia of the hip: How reliable is it in different hands?.

Indian journal of orthopaedics

Orak MM, Onay T, Çağırmaz T, Elibol C, Elibol FD, Centel T.
PMID: 26806967
Indian J Orthop. 2015 Nov-Dec;49(6):610-4. doi: 10.4103/0019-5413.168753.

BACKGROUND: Developmental dysplasia of the hip (DDH) is the most common skeletal dysplasia. Two principal methods used in early diagnosis of DDH are clinical examination and ultrasonographic investigation. Dogruel et al. found a low specificity of clinical examination in...

25 Years of Contrast-Enhanced MRI: Developments, Current Challenges and Future Perspectives.

Advances in therapy

Lohrke J, Frenzel T, Endrikat J, Alves FC, Grist TM, Law M, Lee JM, Leiner T, Li KC, Nikolaou K, Prince MR, Schild HH, Weinreb JC, Yoshikawa K, Pietsch H.
PMID: 26809251
Adv Ther. 2016 Jan;33(1):1-28. doi: 10.1007/s12325-015-0275-4. Epub 2016 Jan 25.

UNLABELLED: In 1988, the first contrast agent specifically designed for magnetic resonance imaging (MRI), gadopentetate dimeglumine (Magnevist(®)), became available for clinical use. Since then, a plethora of studies have investigated the potential of MRI contrast agents for diagnostic imaging...

Multi-centre comparison of five eye movement detection algorithms.

Journal of sleep research

Värri A, Kemp B, Rosa AC, Nielsen KD, Gade J, Penzel T, Hasan J, Hirvonen K, Häkkinen V, Kamphuisen HA, Mourtazaev MS.
PMID: 10607150
J Sleep Res. 1995 Jun;4(2):119-130.

Although various investigators have suggested algorithms for the automatic detection of eye movements during sleep, objective comparisons of the proposed methods have previously been difficult due to different recording arrangements of different investigators. In this study the results of...

Analysis of sleep fragmentation and sleep structure in patients with sleep apnea and normal volunteers.

Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual Conference

Penzel T, Lo CC, Ivanov P, Kesper K, Becker H, Vogelmeier C.
PMID: 17282768
Conf Proc IEEE Eng Med Biol Soc. 2005;2005:2591-4. doi: 10.1109/IEMBS.2005.1616999.

Sleep disorders have a high prevalence. Sleep disorders are recognized first by the complaint of nonrestorative sleep. A quantification of the disorder is done by the investigation in a sleep laboratory. The investigation in the sleep laboratory examines the...

Elevated expression of c-kit in small venous malformations of blue rubber bleb nevus syndrome.

Rare tumors

Mogler C, Beck C, Kulozik A, Penzel R, Schirmacher P, Breuhahn K.
PMID: 21139838
Rare Tumors. 2010 Jun 30;2(2):e36. doi: 10.4081/rt.2010.e36.

The blue rubber bleb nevus syndrome (BRBNS, syn. bean syndrome) is a rare disease characterized by multiple cutaneous and gastrointestinal venous malformations associated with severe bleeding. However, the underlying molecular mechanisms are unknown and no targeted therapeutic approach exists...

Reliability issues for a bolometer detector for ITER at high operating temperatures.

The Review of scientific instruments

Meister H, Kannamüller M, Koll J, Pathak A, Penzel F, Trautmann T, Detemple P, Schmitt S, Langer H.
PMID: 23126898
Rev Sci Instrum. 2012 Oct;83(10):10D724. doi: 10.1063/1.4740256.

The first detector prototypes for the ITER bolometer diagnostic featuring a 12.5 μm thick Pt-absorber have been realized and characterized in laboratory tests. The results show linear dependencies of the calibration parameters and are in line with measurements of...

Cross-modulated amplitudes and frequencies characterize interacting components in complex systems.

Physical review letters

Gans F, Schumann AY, Kantelhardt JW, Penzel T, Fietze I.
PMID: 19392568
Phys Rev Lett. 2009 Mar 06;102(9):098701. doi: 10.1103/PhysRevLett.102.098701. Epub 2009 Mar 04.

The dynamics of complex systems is characterized by oscillatory components on many time scales. To study the interactions between these components we analyze the cross modulation of their instantaneous amplitudes and frequencies, separating synchronous and antisynchronous modulation. We apply...
