Changes in Sr/Ca, Ba/Ca and 87Sr/86Sr ratios between trophic levels in two forest ecosystems in the northeastern U.S.A.
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-04)
The variability and biologicalfractionation of Sr/Ca, Ba/Ca and 87 Sr/ 86 Srratios were studied in a soil–plant–invertebrate–bird food chain in two forested ecosystems withcontrasting calcium availability in the ...
Sonoporation: Mechanical DNA Delivery by Ultrasonic Cavitation
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2002-11)
Development of nonviral gene transfer methods would be a valuable addition to the gene-therapy armamentarium, particularly for localized targeting of specific tissue volumes. Ultrasound can produce a variety of nonthermal ...
Donald J. Reis, MD: Research Mentor Extraordinaire
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-10)
Donald J. Reis, M.D., the late internationally reknowned neuroscientist, had a special talent for mentoring researchers early in their academic careers. His “hands-on” approach to laboratory investigation, his extraoridinary ...
Strain-specific modification of lethality in fucose-deficient mice

Abstract
Inefficient purifying selection: the mammalian Y chromosome in the rodent genus Mus
(Springer-Verlag; Springer Science+Business Media, Inc., 2006-01)
Two related genes with potentially similar functions, one on the Y chromosome and one on the X chromosome, were examined to determine if they evolved differently because of their chromosomal positions. Six hundred fifty-seven ...
Immunocytochemical studies with antisera against Leu-enkephalin and an enkephalin-precursor fragment (BAM-22P) in the rat brain
(Elsevier, 2006-04-07)
Rats given high doses of colchicine (300-400 ug, i.c.v.) were used to investigate the comparative distribution of Leu-enkephalin and bovine adrenal medullary enkephalin-precursor fragment (BAM-22P) in the brain. Leu-enkephalin ...
Dissolution of wollastonite during the experimental manipulation of Hubbard Brook Watershed 1
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-02)
Powdered and pelletized wollastonite (CaSiO 3 ) was applied to an 11.8 ha forested watershed at the Hubbard Brook Experimental Forest (HBEF) in northern New Hampshire, U.S.A. during October of 1999. The dissolution of ...
Expression patterns of neurotrophic factor mRNAs in developing human teeth
(Springer-Verlag, 2002-11)
Neurotrophic factors regulate survival, differentiation, growth and plasticity in the nervous system. In addition, based on their specific and shifting temporospatial expression patterns, neurotrophic factors have been ...
Dynorphin (1-17): Lack of analgesia but evidence for non-opiate electrophysiological and motor effects
(Elsevier, 2006-04-07)
Dynorphin and an opiate-inactive fragment des-Tyr-dynorphin produced similar effects on EEG, motor function and hippocampal unit firing. Naloxone had no effect on the actions of dynorphin in these systems and dynorphin ...
ENHANCER of TRY and CPC 2 ( ETC2 ) reveals redundancy in the region-specific control of trichome development of Arabidopsis
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-05)
>An evolutionarily conserved set of proteins consisting of MYB and bHLH transcription factors and a WD40 domain protein is known to act in concert to control various developmental processes including trichome and root hair ...
