Prenatal Dexamethasone for Congenital Adrenal Hyperplasia: An Ethics Canary in the Modern Medical Mine.

Journal of bioethical inquiry

Dreger A, Feder EK, Tamar-Mattis A.
PMID: 22904609
J Bioeth Inq. 2012 Sep;9(3):277-294. doi: 10.1007/s11673-012-9384-9. Epub 2012 Jul 31.

Following extensive examination of published and unpublished materials, we provide a history of the use of dexamethasone in pregnant women at risk of carrying a female fetus affected by congenital adrenal hyperplasia (CAH). This intervention has been aimed at...

Evidence for spatial clines and mixed geographic modes of speciation for North American cherry-infesting .

Ecology and evolution

Doellman MM, Saint Jean G, Egan SP, Powell THQ, Hood GR, Schuler H, Bruzzese DJ, Glover MM, Smith JJ, Yee WL, Goughnour R, Rull J, Aluja M, Feder JL.
PMID: 33304490
Ecol Evol. 2020 Oct 28;10(23):12727-12744. doi: 10.1002/ece3.6667. eCollection 2020 Dec.

An important criterion for understanding speciation is the geographic context of population divergence. Three major modes of allopatric, parapatric, and sympatric speciation define the extent of spatial overlap and gene flow between diverging populations. However, mixed modes of speciation...

Anomalous modes drive vortex dynamics in confined Bose-Einstein condensates.

Physical review letters

Feder DL, Svidzinsky AA, Fetter AL, Clark CW.
PMID: 11177882
Phys Rev Lett. 2001 Jan 22;86(4):564-7. doi: 10.1103/PhysRevLett.86.564.

The dynamics of vortices in trapped Bose-Einstein condensates are investigated both analytically and numerically. In axially symmetric traps, the critical rotation frequency for metastability of an isolated vortex coincides with the largest vortex precession frequency (or anomalous mode) in...

Generating solitons by phase engineering of a bose-einstein condensate.

Science (New York, N.Y.)

Denschlag J, Simsarian JE, Feder DL, Clark CW, Collins LA, Cubizolles J, Deng L, Hagley EW, Helmerson K, Reinhardt WP, Rolston SL, Schneider BI, Phillips WD.
PMID: 10615056
Science. 2000 Jan 07;287(5450):97-101. doi: 10.1126/science.287.5450.97.

Quantum phase engineering is demonstrated with two techniques that allow the spatial phase distribution of a Bose-Einstein condensate (BEC) to be written and read out. A quantum state was designed and produced by optically imprinting a phase pattern onto...

Superfluid-to-solid crossover in a rotating Bose-Einstein condensate.

Physical review letters

Feder DL, Clark CW.
PMID: 11690400
Phys Rev Lett. 2001 Nov 05;87(19):190401. doi: 10.1103/PhysRevLett.87.190401. Epub 2001 Oct 17.

The properties of a rotating Bose-Einstein condensate confined in a prolate cylindrically symmetric trap are explored both analytically and numerically. As the rotation frequency increases, an ever greater number of vortices are energetically favored. Though the cloud anisotropy and...

Changes in thermotolerance and Hsp70 expression with domestication in Drosophila melanogaster.

Journal of evolutionary biology

Krebs RA, Roberts SP, Bettencourt BR, Feder ME.
PMID: 29280581
J Evol Biol. 2001 Jan 08;14(1):75-82. doi: 10.1046/j.1420-9101.2001.00256.x.

To examine how the duration of laboratory domestication may affect Drosophila stocks used in studies of thermotolerance, we measured expression of the inducible heat-shock protein Hsp70 and survival after heat shock in D. melanogaster strains recently collected from nature...

Spontaneous and Induced Animal Models for Cancer Research.

Diagnostics (Basel, Switzerland)

Onaciu A, Munteanu R, Munteanu VC, Gulei D, Raduly L, Feder RI, Pirlog R, Atanasov AG, Korban SS, Irimie A, Berindan-Neagoe I.
PMID: 32878340
Diagnostics (Basel). 2020 Aug 31;10(9). doi: 10.3390/diagnostics10090660.

Considering the complexity of the current framework in oncology, the relevance of animal models in biomedical research is critical in light of the capacity to produce valuable data with clinical translation. The laboratory mouse is the most common animal...

A taxonomy and cultural analysis of intra-hospital patient transfers.

Research in nursing & health

Rosenberg A, Campbell Britton M, Feder S, Minges K, Hodshon B, Chaudhry SI, Jenq GY, Emerson BL.
PMID: 29722043
Res Nurs Health. 2018 May 02; doi: 10.1002/nur.21875. Epub 2018 May 02.

Existing research on intra-hospital patient transitions focuses chiefly on handoffs, or exchanges of information, between clinicians. Less is known about patient transfers within hospitals, which include but extend beyond the exchange of information. Using participant observations and interviews at...

Standing geographic variation in eclosion time and the genomics of host race formation in .

Ecology and evolution

Doellman MM, Egan SP, Ragland GJ, Meyers PJ, Hood GR, Powell THQ, Lazorchak P, Hahn DA, Berlocher SH, Nosil P, Feder JL.
PMID: 30680122
Ecol Evol. 2018 Dec 14;9(1):393-409. doi: 10.1002/ece3.4758. eCollection 2019 Jan.

Taxa harboring high levels of standing variation may be more likely to adapt to rapid environmental shifts and experience ecological speciation. Here, we characterize geographic and host-related differentiation for 10,241 single nucleotide polymorphisms in

Material Gradients in Stretchable Substrates toward Integrated Electronic Functionality.

Advanced materials (Deerfield Beach, Fla.)

Naserifar N, LeDuc PR, Fedder GK.
PMID: 26989814
Adv Mater. 2016 May;28(18):3584-91. doi: 10.1002/adma.201505818. Epub 2016 Mar 17.

The approach toward a stretchable electronic substrate employs multiple soft polymer layers patterned around silicon chips, which act as surrogates for conventional electronics chips, to create a controllable stiffness gradient. Adding just one intermediate polymer layer results in a...

REGIONAL, LOCAL AND MICROGEOGRAPHIC ALLELE FREQUENCY VARIATION BETWEEN APPLE AND HAWTHORN POPULATIONS OF RHAGOLETIS POMONELLA IN WESTERN MICHIGAN.

Evolution; international journal of organic evolution

Feder JL, Chilcote CA, Bush GL.
PMID: 28567975
Evolution. 1990 May;44(3):595-608. doi: 10.1111/j.1558-5646.1990.tb05940.x.

In the preceding study (Feder et al., 1990), we report that paired apple and hawthorn infesting populations of Rhagoletis pomonella are genetically differentiated for six allozymes. Here, we show that patterns of intra- and inter-host allele frequency variation seen...
