Responses of bullfrog tadpoles to hypoxia and predators
(Springer-Verlag, 2000-10)
Low dissolved oxygen concentrations present numerous challenges for non-air-breathing aquatic organisms. Amphibian larvae and their predators can respond to oxygen levels by altering their behavior and physiology, but the ...
Identification of members of the Wnt signaling pathway in the embryonic pituitary gland
(Springer-Verlag; Springer-Verlag New York Inc., 2001-11)
Prop1 is one of several transcription factors important for the development of the pituitary gland. Downstream targets of PROP1 and other critical pituitary transcription factors remain largely unknown. We have generated ...
Lingual deficits in neurotrophin double knockout mice
(Kluwer Academic Publishers; Springer Science + Business Media, Inc., 2004-12)
Brain-derived neurotrophic factor (BDNF) and Neurotrophin 3 (NT-3) are members of the neurotrophin family and are expressed in the developing and adult tongue papillae. BDNF null-mutated mice exhibit specific impairments ...
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
(Springer-Verlag; Springer-Verlag New York Inc., 2003-02)
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 ...
