Lancet. 2015 Feb 26;385:S80. doi: 10.1016/S0140-6736(15)60395-6.

BACKGROUND: In Bihar state, India, the cure rate of antimonial compounds (eg, sodium stibogluconate) in the treatment of visceral leishmaniasis (VL) has fallen from more than 85% to less than 50%. This reduction has been attributed to long-term, widespread...

Natural phenolic metabolites with anti-angiogenic properties - a review from the chemical point of view.

Considering the many secondary natural metabolites available from plants, phenolic compounds play a particularly important role in human health as they occur in significant amounts in many fruits, vegetables and medicinal plants. In this review natural phenolic compounds of...

Iterative Potts and Blake-Zisserman minimization for the recovery of functions with discontinuities from indirect measurements.

Proceedings. Mathematical, physical, and engineering sciences

Weinmann A, Storath M.
PMID: 27547074
Proc Math Phys Eng Sci. 2015 Apr 08;471(2176):20140638. doi: 10.1098/rspa.2014.0638.

Signals with discontinuities appear in many problems in the applied sciences ranging from mechanics, electrical engineering to biology and medicine. The concrete data acquired are typically discrete, indirect and noisy measurements of some quantities describing the signal under consideration....

Synthesis and proposed crystal structure of a disordered cadmium arsenate apatite Cd5(AsO4)3Cl(1-2x-y)O(x)[symbol: see text](x)OH(y).

Dalton transactions (Cambridge, England : 2003)

Johnson CD, Feldmann J, Macphee DE, Worrall F, Skakle JM.
PMID: 15510284
Dalton Trans. 2004 Nov 07;(21):3611-5. doi: 10.1039/B410483H. Epub 2004 Oct 01.

During a study into the synthesis of minerals composed of mining wastes aimed at improving their immobilisation, a cadmium arsenate apatite has been prepared by hydrothermal methods. The structure of this apatite was analysed by single crystal X-ray diffraction,...

Determination of organometallics in intra-oral air by LT-GC/ICP-MS.

Analytical and bioanalytical chemistry

Riechmann T, Hirner AV, Feldmann J.
PMID: 15067457
Anal Bioanal Chem. 1996 Mar;354(5):620-3. doi: 10.1007/s0021663540620.

Low temperature gas chromatography (LT-GC) coupled on-line with inductively coupled plasma mass spectrometry (ICP-MS) has been used to identify volatile metal and metalloid compounds in human breath. After cryogenic sampling, the gas sample has been separated without any clean-up...

Persistent currents in one dimension: the counterpart of Leggett's theorem.

Physical review letters

Waintal X, Fleury G, Kazymyrenko K, Houzet M, Schmitteckert P, Weinmann D.
PMID: 18851243
Phys Rev Lett. 2008 Sep 05;101(10):106804. doi: 10.1103/PhysRevLett.101.106804. Epub 2008 Sep 05.

We discuss the sign of the persistent current of N electrons in one dimensional rings. Using a topology argument, we establish lower bounds for the free energy in the presence of arbitrary electron-electron interactions and external potentials. Those bounds...

Bringing together compounds of intrinsically different functionality, such as inorganic nanostructures and organic molecules, constitutes a particularly powerful route to creating novel functional devices with synergetic properties found in neither of the constituents. We introduce nanophotonic functional elements combining...

Mode locking using a type II multiple-quantum-well structure as a fast saturable absorber.
