Rev Sci Instrum. 2015 Jul;86(7):073702. doi: 10.1063/1.4926994.

Ultrafast electron probes are powerful tools, complementary to x-ray free-electron lasers, used to study structural dynamics in material, chemical, and biological sciences. High brightness, relativistic electron beams with femtosecond pulse duration can resolve details of the dynamic processes on...

Screening of cancer tissue arrays identifies CXCR4 on adrenocortical carcinoma: correlates with expression and quantification on metastases using .

Expression of the chemokine receptor CXCR4 by many cancers correlates with aggressive clinical behavior. As part of the initial studies in a project whose goal was to quantify CXCR4 expression on cancers non-invasively, we examined CXCR4 expression in cancer...

Fatalities involving illicit drug use in Pretoria, South Africa, for the period 2003 - 2012.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde

Liebenberg J, Du Toit-Prinsloo L, Steenkamp V, Saayman G.
PMID: 27725028

BACKGROUND: Globally, illicit drugs are responsible for many fatalities annually, yet accurate data on the nature and extent of these deaths in South Africa (SA) are lacking.OBJECTIVES: To investigate the presence and profile of illicit drugs detected in deceased...

Ultrafast polarization response of an optically trapped single ferroelectric nanowire.

Nano letters

Nah S, Kuo YH, Chen F, Park J, Sinclair R, Lindenberg AM.
PMID: 25051318
Nano Lett. 2014 Aug 13;14(8):4322-7. doi: 10.1021/nl5011228. Epub 2014 Jul 28.

One-dimensional potassium niobate nanowires are of interest as building blocks in integrated piezoelectric devices, exhibiting large nonlinear optical and piezoelectric responses. Here we present femtosecond measurements of light-induced polarization dynamics within an optically trapped ferroelectric nanowire, using the second-order...

Small Volume Dissolution Testing as a Powerful Method during Pharmaceutical Development.

Pharmaceutics

Scheubel E, Lindenberg M, Beyssac E, Cardot JM.
PMID: 27721362
Pharmaceutics. 2010 Nov 01;2(4):351-363. doi: 10.3390/pharmaceutics2040351.

Standard compendia dissolution apparatus are the first choice for development of new dissolution methods. Nevertheless, limitations coming from the amount of material available, analytical sensitivity, lack of discrimination or biorelevance may warrant the use of non compendial methods. In...

The origin of incipient ferroelectricity in lead telluride.

Nature communications

Jiang MP, Trigo M, Savić I, Fahy S, Murray ÉD, Bray C, Clark J, Henighan T, Kozina M, Chollet M, Glownia JM, Hoffmann MC, Zhu D, Delaire O, May AF, Sales BC, Lindenberg AM, Zalden P, Sato T, Merlin R, Reis DA.
PMID: 27447688
Nat Commun. 2016 Jul 22;7:12291. doi: 10.1038/ncomms12291.

The interactions between electrons and lattice vibrations are fundamental to materials behaviour. In the case of group IV-VI, V and related materials, these interactions are strong, and the materials exist near electronic and structural phase transitions. The prototypical example...

Exploration and trapping of mortal random walkers.

Physical review letters

Yuste SB, Abad E, Lindenberg K.
PMID: 23767708
Phys Rev Lett. 2013 May 31;110(22):220603. doi: 10.1103/PhysRevLett.110.220603. Epub 2013 May 30.

Exploration and trapping properties of random walkers that may evanesce at any time as they walk have seen very little treatment in the literature, and yet a finite lifetime is a frequent occurrence, and its effects on a number...

A theory of social thermoregulation in human primates.

Frontiers in psychology

IJzerman H, Coan JA, Wagemans FM, Missler MA, van Beest I, Lindenberg S, Tops M.
PMID: 25954223
Front Psychol. 2015 Apr 21;6:464. doi: 10.3389/fpsyg.2015.00464. eCollection 2015.

Beyond breathing, the regulation of body temperature-thermoregulation-is one of the most pressing concerns for many animals. A dysregulated body temperature has dire consequences for survival and development. Despite the high frequency of social thermoregulation occurring across many species, little...

Stationary and oscillatory spatial patterns induced by global periodic switching.

Physical review letters

Buceta J, Lindenberg K, Parrondo JM.
PMID: 11801018
Phys Rev Lett. 2002 Jan 14;88(2):024103. doi: 10.1103/PhysRevLett.88.024103. Epub 2001 Dec 26.

We propose a new mechanism for pattern formation based on the global alternation of two dynamics, neither of which exhibits patterns. When driven by either one of the separate dynamics, the system goes to a spatially homogeneous state associated...

Maternal serum supplementation in culture medium benefits maturation of immature human oocytes.
