High potential for weathering and climate effects of non-vascular vegetation in the Late Ordovician.

Nature communications

Porada P, Lenton TM, Pohl A, Weber B, Mander L, Donnadieu Y, Beer C, Pöschl U, Kleidon A.
PMID: 27385026
Nat Commun. 2016 Jul 07;7:12113. doi: 10.1038/ncomms12113.

It has been hypothesized that predecessors of today's bryophytes significantly increased global chemical weathering in the Late Ordovician, thus reducing atmospheric CO2 concentration and contributing to climate cooling and an interval of glaciations. Studies that try to quantify the...

Torres-Sospedra J, Jiménez AR, Knauth S, Moreira A, Beer Y, Fetzer T, Ta VC, Montoliu R, Seco F, Mendoza-Silva GM, Belmonte O, Koukofikis A, Nicolau MJ, Costa A, Meneses F, Ebner F, Deinzer F, Vaufreydaz D, Dao TK, Castelli E.
PMID: 28287447
Sensors (Basel). 2017 Mar 10;17(3). doi: 10.3390/s17030557.

This paper presents the analysis and discussion of the off-site localization competition track, which took place during the Seventh International Conference on Indoor Positioning and Indoor Navigation (IPIN 2016). Five international teams proposed different strategies for smartphone-based indoor positioning...

Convergence of Electronic Structure with the Size of the QM Region: Example of QM/MM NMR Shieldings.

Journal of chemical theory and computation

Flaig D, Beer M, Ochsenfeld C.
PMID: 26588959
J Chem Theory Comput. 2012 Jul 10;8(7):2260-71. doi: 10.1021/ct300036s. Epub 2012 Jun 21.

The influence of the chemical environment on NMR shifts of a central molecular region is studied for several biomolecular and supramolecular systems. To investigate the long-range effects, we systematically increase the QM region until the changes of the NMR...

Anticancer activities of sulindac in prostate cancer cells associated with c-Jun NH2-terminal kinase 1/β-catenin signaling.

Oncology letters

DU J, Guo Y, Bao Y, Xing M, Mahmoud AM, Che Z, Chen Z, Yang W.
PMID: 24959268
Oncol Lett. 2014 Jul;8(1):313-316. doi: 10.3892/ol.2014.2084. Epub 2014 Apr 25.

The non-steroidal anti-inflammatory agent, sulindac, has shown strong effects on cancer prevention in colorectal cancers, however, its anticancer activities on prostate cancer remain unclear. In the current study, human prostate cancer cell lines, LNCaP and PC-3, were treated with...

The cerebellum and psychiatric disorders.

Frontiers in public health

Phillips JR, Hewedi DH, Eissa AM, Moustafa AA.
PMID: 26000269
Front Public Health. 2015 May 05;3:66. doi: 10.3389/fpubh.2015.00066. eCollection 2015.

The cerebellum has been considered for a long time to play a role solely in motor coordination. However, studies over the past two decades have shown that the cerebellum also plays a key role in many motor, cognitive, and...

Ghrelin Levels in Patients With Primary Open-Angle Glaucoma.

Asia-Pacific journal of ophthalmology (Philadelphia, Pa.)

Ghanem AA, Mady SE, Attia TN, Khattab AM, Arafa LF.
PMID: 26107494
Asia Pac J Ophthalmol (Phila). 2014 Mar-Apr;3(2):126-9. doi: 10.1097/APO.0000000000000048.

PURPOSE: This study was aimed to assess the levels of ghrelin in aqueous humor and plasma of human eyes with primary open-angle glaucoma (POAG) and to correlate their concentrations with the severity of glaucoma.DESIGN: This was a case-control, prospective...

Benzo[2,1-c:3,4-c']bis(1,2,3-thiaselenazole) (BSe) and its charge trasfer chemistry. Crystal and electronic structure of [BSe]3[ClO4]2.

Inorganic chemistry

Beer L, Britten JF, Cordes AW, Clements OP, Oakley RT, Pink M, Reed RW.
PMID: 11511219
Inorg Chem. 2001 Aug 27;40(18):4705-9. doi: 10.1021/ic010357j.

The S-Se-N-based heterocycle benzo[2,1-c:3,4-c']bis(1,2,3-thiaselenazole) (BSe) can be prepared by the condensation of 1,4-diaminobenzene-2,3-dithiol with selenium tetrachloride. Crystals of this compound are not isomorphous with the related benzo[2,1-c:3,4-c']bis(1,2,3-dithiazole) (BT); a structure is adopted that allows for more extensive intermolecular Se-...

A pi-stacked 1,2,3-dithiazolyl radical. Preparation and solid state characterization of (Cl2C3NS)(ClC2NS2).

Chemical communications (Cambridge, England)

Beer L, Cordes AW, Haddon RC, Itkis ME, Oakley RT, Reed RW, Robertson CM.
PMID: 12271651
Chem Commun (Camb). 2002 Sep 07;(17):1872-3. doi: 10.1039/b204855h.

Crystals of (Cl2C3NS)(ClC2NS2), an isothiazolyl-substituted 1,2,3-dithiazolyl radical, consist of evenly spaced, slipped pi-stacks; magnetic and conductivity measurements indicate the material is a Mott insulator with sigma RT = 2 x 10(-7) S cm-1.

J Chem Phys. 2007 Jul 07;127(1):014301. doi: 10.1063/1.2743437.

A molecular system exposed to an intense external field is considered. The strength of the field is measured by the number L of electronic states that become populated during this process. In the present article the authors discuss a...

J Phys Chem A. 2006 May 25;110(20):6571-8. doi: 10.1021/jp0617266.

A few years ago, we developed an approach to treat molecular systems exposed to an external, intense, time-dependent field (J. Phys. Chem. A 2003, 107, 4724; J. Chem. Phys. 2003, 119, 6998). Within this study, we encountered two novel...
