The Overlap of Dietary Supplement and Pharmaceutical Use in the MIDUS National Study.

Evidence-based complementary and alternative medicine : eCAM

Kiefer DS, Chase JC, Love GD, Barrett BP.
PMID: 24834100
Evid Based Complement Alternat Med. 2014;2014:823853. doi: 10.1155/2014/823853. Epub 2014 Apr 16.

Introduction. In the United States, dietary supplement (DS) use is common, often takes place outside of the purview of health care providers, and may involve DS in combination with pharmaceuticals. This situation has led to concerns about interactions between...

Arabidopsis D6PK is a lipid domain-dependent mediator of root epidermal planar polarity.

Nature plants

Stanislas T, Hüser A, Barbosa IC, Kiefer CS, Brackmann K, Pietra S, Gustavsson A, Zourelidou M, Schwechheimer C, Grebe M.
PMID: 27251533
Nat Plants. 2015 Nov 02;1:15162. doi: 10.1038/nplants.2015.162.

Development of diverse multicellular organisms relies on coordination of single-cell polarities within the plane of the tissue layer (planar polarity). Cell polarity often involves plasma membrane heterogeneity generated by accumulation of specific lipids and proteins into membrane subdomains. Coordinated...

Handwriting or Typewriting? The Influence of Pen- or Keyboard-Based Writing Training on Reading and Writing Performance in Preschool Children.

Advances in cognitive psychology

Kiefer M, Schuler S, Mayer C, Trumpp NM, Hille K, Sachse S.
PMID: 26770286
Adv Cogn Psychol. 2015 Dec 31;11(4):136-46. doi: 10.5709/acp-0178-7. eCollection 2015.

Digital writing devices associated with the use of computers, tablet PCs, or mobile phones are increasingly replacing writing by hand. It is, however, controversially discussed how writing modes influence reading and writing performance in children at the start of...

Potassium Channels in Chara corallina: CONTROL AND INTERACTION WITH THE ELECTROGENIC H PUMP.

Plant physiology

Keifer DW, Lucas WJ.
PMID: 16662296
Plant Physiol. 1982 Apr;69(4):781-8. doi: 10.1104/pp.69.4.781.

Plasmalemma electrical properties were used to investigate K(+) transport and its control in internodal cells of Chara corallina Klein ex Willd., em R.D.W. Cell exposure to solutions containing 10 mm KCl caused the potential, normally -250 millivolts (average), to...

Rock avalanches caused by earthquakes: source characteristics.

Science (New York, N.Y.)

Keefer DK.
PMID: 17759365
Science. 1984 Mar 23;223(4642):1288-90. doi: 10.1126/science.223.4642.1288.

Study of a worldwide sample of historical earthquakes showed that slopes most susceptible to catastrophic rock avalanches were higher than 150 meters and steeper than 25 degrees. The slopes were undercut by fluvial or glacial erosion, were composed of...

Photoadaptation in marine phytoplankton : changes in spectral absorption and excitation of chlorophyll a fluorescence.

Plant physiology

Neori A, Holm-Hansen O, Mitchell BG, Kiefer DA.
PMID: 16663873
Plant Physiol. 1984 Oct;76(2):518-24. doi: 10.1104/pp.76.2.518.

The optical properties of marine phytoplankton were examined by measuring the absorption spectra and fluorescence excitation spectra of chlorophyll a for natural marine particles collected on glass fiber filters. Samples were collected at different depths from stations in temperate...

Top-down modulation of unconscious 'automatic' processes: A gating framework.

Advances in cognitive psychology

Kiefer M.
PMID: 20517515
Adv Cogn Psychol. 2008 Jul 15;3(1):289-306. doi: 10.2478/v10053-008-0032-2.

In classical theories of automaticity, automatic processes are usually thought to occur autonomously and independently of higher level top-down factors (e.g., Posner & Snyder, 1975). However, already Neumann (1984) pointed out that the cognitive system has to be configured...

Si/Ge junctions formed by nanomembrane bonding.

ACS nano

Kiefer AM, Paskiewicz DM, Clausen AM, Buchwald WR, Soref RA, Lagally MG.
PMID: 21247201
ACS Nano. 2011 Feb 22;5(2):1179-89. doi: 10.1021/nn103149c. Epub 2011 Jan 19.

We demonstrate the feasibility of fabricating heterojunctions of semiconductors with high mismatches in lattice constant and coefficient of thermal expansion by employing nanomembrane bonding. We investigate the structure of and electrical transport across the interface of a Si/Ge bilayer...

Functional performance and grip strength after total hip replacement.

Occupational therapy in health care

Kiefer DE, Emery LJ.
PMID: 23927652
Occup Ther Health Care. 2005;18(4):41-56. doi: 10.1080/J003v18n04_04.

Objective. The progress of adults after total hip replacement (THR) was measured baseline to discharge using the Functional Independence Measure (FIM). Measures of effectiveness and efficiency were investigated. Additionally, although grip strength is frequently evaluated, its relationship to impact...

Executive control over unconscious cognition: attentional sensitization of unconscious information processing.

Frontiers in human neuroscience

Kiefer M.
PMID: 22470329
Front Hum Neurosci. 2012 Mar 23;6:61. doi: 10.3389/fnhum.2012.00061. eCollection 2012.

Unconscious priming is a prototypical example of an automatic process, which is initiated without deliberate intention. Classical theories of automaticity assume that such unconscious automatic processes occur in a purely bottom-up driven fashion independent of executive control mechanisms. In...

Dealing with the unexpected: consumer responses to direct-access BRCA mutation testing.

PeerJ

Francke U, Dijamco C, Kiefer AK, Eriksson N, Moiseff B, Tung JY, Mountain JL.
PMID: 23638402
PeerJ. 2013 Feb 12;1:e8. doi: 10.7717/peerj.8. Print 2013.

Background. Inherited BRCA gene mutations convey a high risk for breast and ovarian cancer, but current guidelines limit BRCA mutation testing to women with early-onset cancer and relatives of mutation-positive cases. Benefits and risks of providing this information directly...
