Full body repetitive behaviors, known as motor stereotypic behaviors (MSBs), are one of the most commonly seen abnormal behaviors in captive non-human primates, and are frequently used as a behavioral measure of well-being. The main goal of this paper...

Discovery of a Missing Link: Detection and Structure of the Elusive Disilicon Carbide Cluster.

The authors examined periventricular white matter, deep white matter, and subcortical magnetic resonance imaging (MRI) high-intensity signals in subjects with late-life depression, probable Alzheimer's disease (DAT), and healthy, age-matched controls. All subjects were healthy and free of major vascular...

Studying the Conformation of a Silaffin-Derived Pentalysine Peptide Embedded in Bioinspired Silica using Solution and Dynamic Nuclear Polarization Magic-Angle Spinning NMR.

Geiger Y, Gottlieb HE, Akbey Ü, Oschkinat H, Goobes G.
PMID: 26451953
J Am Chem Soc. 2016 May 04;138(17):5561-7. doi: 10.1021/jacs.5b07809. Epub 2016 Apr 20.

Smart materials are created in nature at interfaces between biomolecules and solid materials. The ability to probe the structure of functional peptides that engineer biogenic materials at this heterogeneous setting can be facilitated tremendously by use of DNP-enhanced solid-state...

Novel crown-ether-methylenediphosphonotetrathioate hybrids as Zn(II) chelators.

Dalton transactions (Cambridge, England : 2003)

Meltzer D, Gottlieb HE, Amir A, Shimon LJ, Fischer B.
PMID: 26592926
Dalton Trans. 2015 Dec 28;44(48):21073-80. doi: 10.1039/c5dt03935e. Epub 2015 Nov 23.

Hybrids of methylenediphosphonotetrathioate and crown-ether (MDPT-CE) were synthesized forming 7-,8-,9-,10- and 13-membered rings. Both 7- and 13-membered ring-containing compounds were found to be highly stable to air-oxidation for at least four weeks. These hybrids bind Zn(II) by both MDPT...

Polyethylated aromatic rings: conformation and rotational barriers of 1,2,3,4,5,6,7,8-octaethylanthracene, 1,2,3,4,6,7,8-heptaethylfluorene, and 1,2,3,4,5,6,7,8-octaethylfluorene.

The Journal of organic chemistry

Marks V, Gottlieb HE, Melman A, Byk G, Cohen S, Biali SE.
PMID: 11578225
J Org Chem. 2001 Oct 05;66(20):6711-8. doi: 10.1021/jo0105235.

1,2,3,4,5,6,7,8-Octaethylanthracene (5), 1,2,3,4,6,7,8-heptaethylfluorene (7), and 1,2,3,4,5,6,7,8-octaethylfluorene (8) were synthesized by Friedel-Crafts ethylations of 9,10-dihydroanthracene and fluorene. MM3 calculations indicate that the two ethylated six-membered rings of 5 and 7 are conformationally independent. According to the calculations, two low-energy conformers...

Crystal structure and rotational barrier of octakis(bromomethyl)naphthalene.

The Journal of organic chemistry

Simaan S, Marks V, Gottlieb HE, Stanger A, Biali SE.
PMID: 12530901
J Org Chem. 2003 Jan 24;68(2):637-40. doi: 10.1021/jo026343s.

Octakis(bromomethyl)naphthalene (4) adopts in the crystal a chiral conformation with a helical central naphthalene core and the bromomethyl groups disposed in an alternate up-down "in" arrangement. According to MM3 calculations, this conformation is less stable than the corresponding all...

Models are sometimes developed on the premise that there are no differences between two or more conditions regardless of experimental manipulation. This article argues that unless a very sensitive experiment (or series of experiments) was conducted, such conclusions are...
