Robust spot-poled membrane hydrophones for measurement of large amplitude pressure waveforms generated by high intensity therapeutic ultrasonic transducers.

The Journal of the Acoustical Society of America

Wilkens V, Sonntag S, Georg O.
PMID: 27036269
J Acoust Soc Am. 2016 Mar;139(3):1319-32. doi: 10.1121/1.4944693.

The output characterization of medical high intensity therapeutic ultrasonic devices poses several challenges for the hydrophones to be used for pressure measurements. For measurements at clinical levels in the focal region, extreme robustness, broad bandwidth, large dynamic range, and...

JMIR Mhealth Uhealth. 2015 Jul 02;3(3):e74. doi: 10.2196/mhealth.4021.

BACKGROUND: Patient adherence to medication regimens is critical in most chronic disease treatment plans. This study uses a patient-centered tablet app, "My Interventional Drug-Eluting Stent Educational App (MyIDEA)." This is an educational program designed to improve patient medication adherence.OBJECTIVE:...

Determinants for Sustained Use of an Activity Tracker: Observational Study.

JMIR mHealth and uHealth

Hermsen S, Moons J, Kerkhof P, Wiekens C, De Groot M.
PMID: 29084709
JMIR Mhealth Uhealth. 2017 Oct 30;5(10):e164. doi: 10.2196/mhealth.7311.

BACKGROUND: A lack of physical activity is considered to cause 6% of deaths globally. Feedback from wearables such as activity trackers has the potential to encourage daily physical activity. To date, little research is available on the natural development...

Comparison of hip joint cartilage degeneration assessed by histology and ex vivo optical coherence tomography.

Orthopedic reviews

Pilge H, Huber-van der Velden K, Herten M, Kurzidem S, Krauspe R, Bittersohl B, Zilkens C.

Wilkens S.
PMID: 25750732
F1000Prime Rep. 2015 Feb 03;7:14. doi: 10.12703/P7-14. eCollection 2015.

All living organisms depend on primary and secondary membrane transport for the supply of external nutrients and removal or sequestration of unwanted (toxic) compounds. Due to the chemical diversity of cellular molecules, it comes as no surprise that a...

Transcriptional analysis of antiviral small molecule therapeutics as agonists of the RLR pathway.

Genomics data

Green RR, Wilkins C, Pattabhi S, Dong R, Loo Y, Gale M.
PMID: 26981429
Genom Data. 2016 Feb 01;7:290-2. doi: 10.1016/j.gdata.2016.01.020. eCollection 2016 Mar.

The recognition of pathogen associated molecular patterns (PAMPs) by pattern recognition receptors (PRR) during viral infection initiates the induction of antiviral signaling pathways, including activation of the Interferon Regulator Factor 3 (IRF3). We identified small molecule compounds that activate...

The influence of the sample preparation parameters (the choice of the matrix, matrix:analyte ratio, salt:analyte ratio) was investigated and optimal conditions were established for the MALDI time-of-flight mass spectrometry analysis of the poly(styrene-co-pentafluorostyrene) copolymers. These were synthesized by atom...

Classical information and distillable entanglement.
