Hypertension Control, Apparent Treatment Resistance, and Outcomes in the Elderly Population With Chronic Kidney Disease.

Kidney international reports

Kaboré J, Metzger M, Helmer C, Berr C, Tzourio C, Drueke TB, Massy ZA, Stengel B.
PMID: 29142956
Kidney Int Rep. 2016 Oct 31;2(2):180-191. doi: 10.1016/j.ekir.2016.10.006. eCollection 2017 Mar.

INTRODUCTION: Chronic kidney disease (CKD) is often associated with poor hypertension control and treatment resistance, but whether CKD modifies the effect of hypertension control on outcomes is unknown.METHODS: We studied 10-year mortality and cardiovascular events according to hypertension control...

Structural model of standard ultrasonic transducer array developed for FEM analysis of mechanical crosstalk.

Ultrasonics

Celmer M, Opieliński KJ, Dopierała M.
PMID: 28610713
Ultrasonics. 2018 Feb;83:114-119. doi: 10.1016/j.ultras.2017.06.006. Epub 2017 Jun 03.

One of the reasons of distortions in ultrasonic imaging are crosstalk effects. They can be divided into groups according to the way of their formation. One of them is constituted by mechanical crosstalk, which is propagated by a construction...

Gene analysis for longitudinal family data using random-effects models.

BMC proceedings

Houwing-Duistermaat JJ, Helmer Q, Balliu B, van den Akker E, Tsonaka R, Uh HW.
PMID: 25519415
BMC Proc. 2014 Jun 17;8:S88. doi: 10.1186/1753-6561-8-S1-S88. eCollection 2014.

We have extended our recently developed 2-step approach for gene-based analysis to the family design and to the analysis of rare variants. The goal of this approach is to study the joint effect of multiple single-nucleotide polymorphisms that belong...

Parts per trillion sensitivity for ethane in air with an optical parametric oscillator cavity leak-out spectrometer.

Optics letters

von Basum G, Halmer D, Hering P, Mürtz M, Schiller S, Müller F, Popp A, Kühnemann F.
PMID: 15119381
Opt Lett. 2004 Apr 15;29(8):797-9. doi: 10.1364/ol.29.000797.

Spectroscopic detection of ethane in the 3-microm wavelength region was performed by means of a cw optical parametric oscillator and cavity leak-out. We achieved a minimum detectable absorption coefficient of 1.6 x 10(-10) cm 1/square root of Hz, corresponding...

Conf Proc IEEE Eng Med Biol Soc. 2004;2004:2746-9. doi: 10.1109/IEMBS.2004.1403786.

We have developed a new navigation approach for computer-assisted interventional radiology. Our system combines a virtual reality display with high-fidelity haptic rendering to provide assistance and guidance of the medical gesture. Specifically, the system is designed to improve the...

Interaction of alkali metals with perylene-3,4,9,10-tetracarboxylic-dianhydride thin films studied by IR spectroscopy.

The Journal of chemical physics

Heimer K, Wuesten J, Lach S, Ziegler Ch.
PMID: 17477626
J Chem Phys. 2007 Apr 28;126(16):164709. doi: 10.1063/1.2722748.

In order to clarify the doping behavior of different alkali metals in perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA), Fourier transform infrared spectra of PTCDA thin films doped with sodium, potassium, and cesium were measured and compared. Furthermore the vibrational properties were calculated...

Drug choice, spatial distribution, HIV risk, and HIV prevalence among injection drug users in St. Petersburg, Russia.

Harm reduction journal

Kruse GR, Barbour R, Heimer R, Shaboltas AV, Toussova OV, Hoffman IF, Kozlov AP.
PMID: 19646255
Harm Reduct J. 2009 Jul 31;6:22. doi: 10.1186/1477-7517-6-22.

BACKGROUND: The HIV epidemic in Russia has been driven by the unsafe injection of drugs, predominantly heroin and the ephedrine derived psychostimulants. Understanding differences in HIV risk behaviors among injectors associated with different substances has important implications for prevention...

A qualitative study of overdose responses among Chicago IDUs.

Sherman SG, Gann DS, Scott G, Carlberg S, Bigg D, Heimer R.
PMID: 18218071
Harm Reduct J. 2008 Jan 24;5:2. doi: 10.1186/1477-7517-5-2.

BACKGROUND: Opioid overdose is a leading cause of death among injection drug users. Over half of injection drug users report at least one nonfatal overdose during their lifetime. Death from opioid overdose rarely occurs instantaneously, but rather over the...

Concealed maternal blood glucose excursions correlate with birth weight centile.

J Diabetes Sci Technol. 2008 May;2(3):456-60. doi: 10.1177/193229680800200315.

BACKGROUND: The objective of this study was to test the hypothesis that maternal blood glucose excursions correlate with deviation from optimized birth weight.METHODS: Patients were recruited for 3-day continuous glucose monitoring (CGM) plus self-blood glucose monitoring followed by routine...

Spectral optical-density measurements of small particles and breast tissues.

Applied optics

Das BB, Yoo KM, Liu F, Cleary J, Prudente R, Celmer E, Alfano RR.
PMID: 20802723
Appl Opt. 1993 Feb 01;32(4):549-53. doi: 10.1364/AO.32.000549.

The optical density of breast tissues without blood is found to be relatively constant from 320 to 800 nm, indicating a relatively independent scattering cross section over this wavelength region.
