Putatively free-living 'Endomicrobia'- ancestors of the intracellular symbionts of termite gut flagellates?.

Environmental microbiology reports

Ikeda-Ohtsubo W, Faivre N, Brune A.
PMID: 23766225
Environ Microbiol Rep. 2010 Aug;2(4):554-9. doi: 10.1111/j.1758-2229.2009.00124.x. Epub 2010 Jan 05.

Endomicrobia represent a candidate class in the Elusimicrobia phylum (formerly Termite Group 1) and were originally described as obligate intracellular symbionts of gut flagellates in lower termites. However, 16S rRNA gene sequences of Endomicrobia have been detected also in...

Reaction-induced cluster ripening and initial size-dependent reaction rates for CO oxidation on Pt(n)/TiO2(110)-(1×1).

Journal of the American Chemical Society

Bonanni S, Aït-Mansour K, Harbich W, Brune H.
PMID: 24870394
J Am Chem Soc. 2014 Jun 18;136(24):8702-7. doi: 10.1021/ja502867r. Epub 2014 Jun 09.

We determined the CO oxidation rates for size-selected Ptn (n ∈ {3,7,10}) clusters deposited onto TiO2(110). In addition, we investigated the cluster morphologies and their mean sizes before and after the reaction. While the clusters are fairly stable upon...

Origin of Perpendicular Magnetic Anisotropy and Large Orbital Moment in Fe Atoms on MgO.

Physical review letters

Baumann S, Donati F, Stepanow S, Rusponi S, Paul W, Gangopadhyay S, Rau IG, Pacchioni GE, Gragnaniello L, Pivetta M, Dreiser J, Piamonteze C, Lutz CP, Macfarlane RM, Jones BA, Gambardella P, Heinrich AJ, Brune H.
PMID: 26684139
Phys Rev Lett. 2015 Dec 04;115(23):237202. doi: 10.1103/PhysRevLett.115.237202. Epub 2015 Dec 01.

We report on the magnetic properties of individual Fe atoms deposited on MgO(100) thin films probed by x-ray magnetic circular dichroism and scanning tunneling spectroscopy. We show that the Fe atoms have strong perpendicular magnetic anisotropy with a zero-field...

Activity of mitochondrial respiratory chain is increased by chronic administration of antidepressants.

Scaini G, Maggi DD, De-Nês BT, Gonçalves CL, Ferreira GK, Teodorak BP, Bez GD, Ferreira GC, Schuck PF, Quevedo J, Streck EL.
PMID: 26952897
Acta Neuropsychiatr. 2011 Jun;23(3):112-8. doi: 10.1111/j.1601-5215.2011.00548.x.

OBJECTIVE: Depressive disorders, including major depression, are serious and disabling for affected patients. Although the neurobiological understanding of major depressive disorder focuses mainly on the monoamine hypothesis, the exact pathophysiology of depression is not fully understood.METHODS: Animals received daily...

Fluorescence Activated Cell Sorting (FACS) and Gene Expression Analysis of Fos-expressing Neurons from Fresh and Frozen Rat Brain Tissue.

Journal of visualized experiments : JoVE

Rubio FJ, Li X, Liu QR, Cimbro R, Hope BT.
PMID: 27685012
J Vis Exp. 2016 Aug 27;(114). doi: 10.3791/54358.

The study of neuroplasticity and molecular alterations in learned behaviors is switching from the study of whole brain regions to the study of specific sets of sparsely distributed activated neurons called neuronal ensembles that mediate learned associations. Fluorescence Activated...

In vitro effect of antipsychotics on brain energy metabolism parameters in the brain of rats.

Acta neuropsychiatrica

Scaini G, Rochi N, Morais MO, Maggi DD, De-Nês BT, Quevedo J, Streck EL.
PMID: 26953070
Acta Neuropsychiatr. 2013 Feb;25(1):18-26. doi: 10.1111/j.1601-5215.2012.00650.x.

OBJECTIVE: Typical and atypical antipsychotic drugs have been shown to have different clinical, biochemical and behavioural profiles. It is well described that impairment of metabolism, especially in the mitochondria, leads to oxidative stress and neuronal death and has been...

Whole Genome Expression Analysis in a Mouse Model of Tauopathy Identifies MECP2 as a Possible Regulator of Tau Pathology.

Frontiers in molecular neuroscience

Maphis NM, Jiang S, Binder J, Wright C, Gopalan B, Lamb BT, Bhaskar K.
PMID: 28367114
Front Mol Neurosci. 2017 Mar 17;10:69. doi: 10.3389/fnmol.2017.00069. eCollection 2017.

Increasing evidence suggests that hyperphosphorylation and aggregation of microtubule-associated protein tau (MAPT or tau) correlates with the development of cognitive impairment in Alzheimer's disease (AD) and related tauopathies. While numerous attempts have been made to model AD-relevant tau pathology...

Distinction of nuclear spin states with the scanning tunneling microscope.

Physical review letters

Natterer FD, Patthey F, Brune H.
PMID: 24206501
Phys Rev Lett. 2013 Oct 25;111(17):175303. doi: 10.1103/PhysRevLett.111.175303. Epub 2013 Oct 24.

We demonstrate rotational excitation spectroscopy with the scanning tunneling microscope for physisorbed H(2) and its isotopes HD and D(2). The observed excitation energies are very close to the gas phase values and show the expected scaling with the moment...

Mid-Burdigalian Paratethyan alkenone record reveals link between orbital forcing, Antarctic ice-sheet dynamics and European climate at the verge to Miocene Climate Optimum.

Global and planetary change

Glob Planet Change. 2014 Dec;123:36-43. doi: 10.1016/j.gloplacha.2014.10.011.

The Early Ottnangian Cooling (EOC), a distinct cold-spell in European climate at ~ 18 Ma preceding the Miocene Climate Optimum, is frequently reported in Paratethys records; however, the duration, magnitude, and underlying causes are poorly understood. A new palaeoclimatic...
