Tumor volume measurement error using computed tomography imaging in a phase II clinical trial in lung cancer.

Journal of medical imaging (Bellingham, Wash.)

Henschke CI, Yankelevitz DF, Yip R, Archer V, Zahlmann G, Krishnan K, Helba B, Avila R.
PMID: 27660808
J Med Imaging (Bellingham). 2016 Jul;3(3):035505. doi: 10.1117/1.JMI.3.3.035505. Epub 2016 Sep 20.

To address the error introduced by computed tomography (CT) scanners when assessing volume and unidimensional measurement of solid tumors, we scanned a precision manufactured pocket phantom simultaneously with patients enrolled in a lung cancer clinical trial. Dedicated software quantified...

Are intramolecular frustrated Lewis pairs also intramolecular catalysts? A theoretical study on H2 activation.

Physical chemistry chemical physics : PCCP

Zeonjuk LL, St Petkov P, Heine T, Röschenthaler GV, Eicher J, Vankova N.
PMID: 25812167
Phys Chem Chem Phys. 2015 Apr 28;17(16):10687-98. doi: 10.1039/c5cp00368g.

We investigate computationally a series of intramolecular frustrated Lewis pairs (FLPs), with the general formula Mes2PCHRCH2B(C6F5)2, that are known from the literature to either activate molecular hydrogen (FLPs with R = H (1) or Me (4)), or remain inert...

Lovastatin lactone may improve irritable bowel syndrome with constipation (IBS-C) by inhibiting enzymes in the archaeal methanogenesis pathway.

F1000Research

Muskal SM, Sliman J, Kokai-Kun J, Pimentel M, Wacher V, Gottlieb K.
PMID: 27347377
F1000Res. 2016 Apr 08;5:606. doi: 10.12688/f1000research.8406.2. eCollection 2016.

UNLABELLED: Methane produced by the methanoarchaeon Methanobrevibacter smithii ( M. smithii) has been linked to constipation, irritable bowel syndrome with constipation (IBS-C), and obesity. Lovastatin, which demonstrates a cholesterol-lowering effect by the inhibition of HMG-CoA reductase, may also have...

Synthesis of multivalent host and guest molecules for the construction of multithreaded diamide pseudorotaxanes.

Beilstein journal of organic chemistry

Löw NL, Dzyuba EV, Brusilowskij B, Kaufmann L, Franzmann E, Maison W, Brandt E, Aicher D, Wiehe A, Schalley CA.
PMID: 22423290
Beilstein J Org Chem. 2012;8:234-245. doi: 10.3762/bjoc.8.24. Epub 2012 Feb 09.

A series of di-, tri- and tetravalent axles and wheels for the synthesis of pseudorotaxanes bearing the tetralactam macrocycle/diamide axle binding motif was prepared. Starting from iodinated monovalent precursors, Sonogashira cross-coupling reactions were utilized to couple the binding sites...

Increasing the efficiency of the ring-opening reaction of photochromic indolylfulgides by optical pre-excitation.

Chemical physics letters

Brust T, Draxler S, Eicher J, Lees WJ, Rück-Braun K, Zinth W, Braun M.
PMID: 20514344
Chem Phys Lett. 2010 Apr 09;489(4):175-180. doi: 10.1016/j.cplett.2010.02.071.

For three indolylfulgides the quantum efficiency of the ring-opening reaction upon pre-excitation is investigated in a multipulse experiment. The quantum efficiency grows by factor of up to 3.4, when the pre-excitation pulse immediately precedes the excitation process. The change...

Towards plant-odor-related olfactory neuroethology in Drosophila.

Chemoecology

Hansson BS, Knaden M, Sachse S, Stensmyr MC, Wicher D.
PMID: 20461131
Chemoecology. 2010 Jun;20(2):51-61. doi: 10.1007/s00049-009-0033-7. Epub 2009 Dec 20.

Drosophila melanogaster is today one of the three foremost models in olfactory research, paralleled only by the mouse and the nematode. In the last years, immense progress has been achieved by combining neurogenetic tools with neurophysiology, anatomy, chemistry, and...

Eicher W.
PMID: 8484199
Versicherungsmedizin. 1993 Apr 01;45(2):50-3.

The problem area of unconventional methods of treatment involves addressing a complex web of legal questions (constitutional law, criminal law, medical liability law, social insurance law, medical professional law). However, proceeding from the basis of statutory health insurance law,...

Randomized trial of nutrition education added to internet-based information and exercise at the work place for weight loss in a racially diverse population of overweight women.

Nutrition & diabetes
