Education and Genetic Risk Modulate Hippocampal Structure in Alzheimer's Disease.

Aging and disease

Baumgaertel J, Haussmann R, Gruschwitz A, Werner A, Osterrath A, Lange J, Donix KL, Linn J, Donix M.
PMID: 27699079
Aging Dis. 2016 Oct 01;7(5):553-560. doi: 10.14336/AD.2016.0305. eCollection 2016 Oct.

Genetic and environmental protective factors and risks modulate brain structure and function in neurodegenerative diseases and their preclinical stages. We wanted to investigate whether the years of formal education, a proxy measure for cognitive reserve, would influence hippocampal structure...

Many-Body Localization Implies that Eigenvectors are Matrix-Product States.

Physical review letters

Friesdorf M, Werner AH, Brown W, Scholz VB, Eisert J.
PMID: 25978216
Phys Rev Lett. 2015 May 01;114(17):170505. doi: 10.1103/PhysRevLett.114.170505. Epub 2015 May 01.

The phenomenon of many-body localization has received a lot of attention recently, both for its implications in condensed-matter physics of allowing systems to be an insulator even at nonzero temperature as well as in the context of the foundations...

Electric quantum walks with individual atoms.

Physical review letters

Genske M, Alt W, Steffen A, Werner AH, Werner RF, Meschede D, Alberti A.
PMID: 23705697
Phys Rev Lett. 2013 May 10;110(19):190601. doi: 10.1103/PhysRevLett.110.190601. Epub 2013 May 07.

We report on the experimental realization of electric quantum walks, which mimic the effect of an electric field on a charged particle in a lattice. Starting from a textbook implementation of discrete-time quantum walks, we introduce an extra operation...

[Interpersonal differentiation of the enzymatic pattern in the polymorphic hydroidHydractinia echinata].

Wilhelm Roux's archives of developmental biology

May G, Müller WA.
PMID: 28304649
Wilehm Roux Arch Dev Biol. 1975 Mar;177(1):53-59. doi: 10.1007/BF00848627.

Interpersonal differentiation between gasterozooids and gonozooids, inHydractinia echinata, is reflected by the pattern of extractable enzyme activities. With regard to their activity levels in the different hydranths the enzymes can be arranged in two groups. In the first group...

Exploratory investigation of PSCA-protein expression in primary breast cancer patients reveals a link to HER2/neu overexpression.

Oncotarget

Link T, Kuithan F, Ehninger A, Kuhlmann JD, Kramer M, Werner A, Gatzweiler A, Richter B, Ehninger G, Baretton G, Bachmann M, Wimberger P, Friedrich K.

Oncotarget. 2017 Apr 29;8(33):54592-54603. doi: 10.18632/oncotarget.17523. eCollection 2017 Aug 15.

BACKGROUND: Prostate stem cell antigen (PSCA) has been suggested as biomarker and therapeutic target for prostate cancer. Recent advances showed that PSCA is up-regulated in other cancer entities, such as bladder or pancreatic cancer. However, the clinical relevance of...

[Induction of metamorphosis in planulae : I. The bacterial inducer].

Wilhelm Roux' Archiv fur Entwicklungsmechanik der Organismen

Müller WA.
PMID: 28304706
Wilhelm Roux Arch Entwickl Mech Org. 1973 Jun;173(2):107-121. doi: 10.1007/BF00575137.

1. The metamorphosis of the planulae ofHydractinia echinata (Hydrozoa) is induced by certain marine, gramnegative bacteria which at the end of the exponential growth release a stimulating principle. 2. The stimulus is liberated by stationary cells previously cultivated at...

[Induction of metamorphosis in planulae : II. Induction by monovalent cations: The significance of the Gibbs-Donnan ratio and of the Na.

Wilhelm Roux' Archiv fur Entwicklungsmechanik der Organismen

Müller WA, Buchal G.
PMID: 28304707
Wilhelm Roux Arch Entwickl Mech Org. 1973 Jun;173(2):122-135. doi: 10.1007/BF00575138.

1. The metamorphosis of the planulae ofHydractinia echinata (Hydrozoa) can be induced by a pulse-type (2-3 hrs) exposure to the ions of caesium, rubidium, lithium, and potassium. With mixtures of seawater with isoosmolar solutions of the chlorides of these...

Quantitative analysis of an inhibitory gradient field in the hydrozoan stolon.

Wilhelm Roux's archives of developmental biology

Müller WA, Plickert G.
PMID: 28305422
Wilehm Roux Arch Dev Biol. 1982 Jan;191(1):56-63. doi: 10.1007/BF00848546.

An inhibitory field which emanates from the mobile tips of elongating stolons of colonial hydroids has been identified and analyzed. It extends proximally with decreasing intensity for about 400-700 μm and ensures that branching sites occur at appropriate distances...

Routine cognitive screening in a neurology practice: Effect on physician behavior.

Neurology. Clinical practice

Rosenbloom M, Borson S, Barclay T, Hanson LR, Werner A, Stuck L, McCarten J.

BACKGROUND: Alzheimer disease is one of the most prevalent and costly neurologic disorders. American Academy of Neurology guidelines call for diagnosis and treatment when dementia is present, but provide no specific instruction relating to cognitive screening.METHODS: Our center piloted...

Positive Tensor Network Approach for Simulating Open Quantum Many-Body Systems.

Physical review letters

Werner AH, Jaschke D, Silvi P, Kliesch M, Calarco T, Eisert J, Montangero S.

Open quantum many-body systems play an important role in quantum optics and condensed matter physics, and capture phenomena like transport, the interplay between Hamiltonian and incoherent dynamics, and topological order generated by dissipation. We introduce a versatile and practical...
