Microcirculation: Electrophysiological Basis For The Response Of Endothelial Cells To Inflammatory Mediators-Bradykinin, Kai Miao
Electronic Theses and Dissertations
Using conventional microelectrodes, I studied the electrical basis for determining the resting V$\sb{\rm m}$ in intact EC's from hamsters. The resting V$\sb{\rm m}$ were found to be $-$40 mV for aortic EC's and $-$43 mV for vena caval EC's. The contributions of ions to the resting V$\sb{\rm m}$ of aortic EC's were compared in terms of the transference number (t$\sb{\rm ion}$). To develop a technique for in situ monitoring changes in V$\sb{\rm m}$ of postcapillary venular EC's in the hamster mesentery, a voltage-sensitive fluorescent probe, bisoxonol, was used to load the cells and the fluorescence signals were analyzed under an …
A Thyroid Hormone-Regulated Gene In Xenopus Laevis Encodes A Type Iii Iodothyronine 5-Deiodinase., Donald L. St Germain, Robert Schwartzman, Walburga Croteau, Akira Kanamori, Zhou Wang, Donald D. Brown, Valerie Galton
A Thyroid Hormone-Regulated Gene In Xenopus Laevis Encodes A Type Iii Iodothyronine 5-Deiodinase., Donald L. St Germain, Robert Schwartzman, Walburga Croteau, Akira Kanamori, Zhou Wang, Donald D. Brown, Valerie Galton

The type III iodothyronine 5-deiodinase metabolizes thyroxine and 3,5,3'-triiodothyronine to inactive metabolites by catalyzing the removal of iodine from the inner ring. The enzyme is expressed in a tissue-specific pattern during particular stages of development in amphibia, birds, and mammals. Recently, a PCR-based subtractive hybridization technique has been used to isolate cDNAs prepared from Xenopus laevis tadpole tail mRNA that represent genes upregulated by thyroid hormone during metamorphosis. Sequence analysis of one of these cDNAs (XL-15) revealed regions of homology to the mRNA encoding the rat type I (outer ring) 5'-deiodinase, including a conserved UGA codon that encodes selenocysteine in …
Bcl-2 Protein Expression Is Widespread In The Developing Nervous-System And Retained In The Adult Pns, Diane E. Merry, Deborah J. Veis, William F. Hickey, Stanley J. Korsmeyer
Bcl-2 Protein Expression Is Widespread In The Developing Nervous-System And Retained In The Adult Pns, Diane E. Merry, Deborah J. Veis, William F. Hickey, Stanley J. Korsmeyer
Dartmouth Scholarship
Cell death is a common feature of neural development in all vertebrates. The bcl-2 proto-oncogene has been shown to protect a variety of cell types from programmed cell death. We have examined the distribution of bcl-2 protein in the developing and adult nervous systems. bcl-2 protein is widespread during embryonic development. Proliferating neuroepithelial cells of ventricular zones as well as the postmitotic cells of the cortical plate, cerebellum, hippocampus and spinal cord express bcl-2. Postnatally, bcl-2 is principally retained in the granule cells of the cerebellum and dentate gyrus of the hippocampus. bcl-2 expression in the CNS declines with aging. …
Coping With The Risk Of Cancer In Children Living Near Power Lines, Eileen N. Abt
Coping With The Risk Of Cancer In Children Living Near Power Lines, Eileen N. Abt
RISK: Health, Safety & Environment (1990-2002)
Ms. Abt briefly summarizes evidence linking power lines with a possible increase in risk of childhood cancer. She also recounts how, although many experts remain skeptical of causality, public fears, whether or not warranted, have themselves created serious problems. Finally, she proposes ways to address those problems.
Morphometric Analysis Of Enteric Lesions In C3h/Hen Mice Inoculated With Serpulina Hyodysenteriae Serotypes 2 And 4 With Or Without Oral Streptomycin Pretreatment, Jagannatha V. Mysore, Gerald Duhamel
Morphometric Analysis Of Enteric Lesions In C3h/Hen Mice Inoculated With Serpulina Hyodysenteriae Serotypes 2 And 4 With Or Without Oral Streptomycin Pretreatment, Jagannatha V. Mysore, Gerald Duhamel
School of Veterinary and Biomedical Sciences: Faculty Publications
The segmental distribution and sequential progression and the role of the indigenous bacterial flora in the development of enteric lesions associated with Serpulina hyodysenteriae infection in laboratory mice have not been defined. We examined the distribution and sequential morphometric changes in the large intestine of mice orally inoculated with S. hyodysenteriae serotypes 2 and 4. To determine the role of colonization resistance conferred by the indigenous bacterial flora, 40 female C3H/HeN mice were administered water alone or water containing 5 mg/mL streptomycin sulfate ad libitum for seven days prior to orogastric inoculation either with S. hyodysenteriae or sterile trypticase soy …

Outpatient Administration Of Paclitaxel, Siu Fun Wong
Pharmacy Faculty Articles and Research
Paclitaxel (Taxol®, Bristol-Meyers Squibb), anti neoplastic agent made from the bark of the Pacific yew tree, is undoubtedly one of the most exciting agents to be evaluated over the past decade. Paclitaxel has demonstrated significant promise against ovarian and metastatic breast cancer, and appears to be the most effective single agent to date for non-small-cell lung cancer in trials conducted by Eastern Cooperative Oncology Group (ECOG).
