Publikováno v: Journal of Pharmaceutical Sciences. 85:899-902
The bioavailability of scopolamine in three dosage forms was compared in 12 healthy nonsmoking male volunteers. Subjects received 0.4-mg doses of scopolamine bromide in intravenous (IV), intranasal (IN), or oral (PO) dosage forms on three occasions,

Changes in sympathoadrenal response to standing in humans after spaceflight
Autor: W. J. Williams, Peggy A. Whitson, J. B. Charles, Nitza M. Cintron
Publikováno v: Journal of Applied Physiology. 79:428-433
Plasma catecholamine levels and cardiovascular responses to standing were determined in astronauts before and after several Space Shuttle missions. Blood pressure, heart rate, and cardiac output were measured and blood samples for catecholamine analy

Metabolie Changes Observed in Astronauts
Autor: Jane M. Krauhs, Nitza M. Cintron, Carolyn S. Leach
Publikováno v: The Journal of Clinical Pharmacology. 31:921-927
Study of metabolic alterations that occur during space flight can provide insight into mechanisms of physiologic regulation. Results of medical experiments with astronauts reveal rapid loss of volume (2 L) from the legs and a transient early increase

Immunoreactive prohormone atrial natriuretic peptides 1–30 and 31–67: Existence of a single circulating amino-terminal peptide
Autor: Yu-Ming Chen, Nitza M. Cintron, Peggy A. Whitson
Publikováno v: Biochemical and Biophysical Research Communications. 166:794-800
Sep-Pak C18 extraction of human plasma and radioimmunoassay using antibodies which recognize atrial natriuretic peptide (99-128) and the prohormone sequences 1-30 and 31-67 resulted in mean values from 20 normal subjects of 26.2 (+/- 9.2), 362 (+/- 1

Alterations in renal stone risk factors after space flight
Autor: Peggy A. Whitson, Charles Y.C. Pak, Nitza M. Cintron, Robert A. Pietrzyk
Publikováno v: The Journal of urology. 150(3)
Exposure to the microgravity environment of space produces a number of physiological changes of metabolic and environmental origin that could increase the potential for renal stone formation. Metabolic, environmental and physicochemical factors that

Insulin-like growth factor-I binds selectively to human peripheral blood monocytes and B-lymphocytes
Autor: Richard T. Meehan, Richard W. Furlanetto, Laureen S. Neale, Nitza M. Cintron, Charles A. Stuart
Publikováno v: The Journal of clinical endocrinology and metabolism. 72(5)
Insulin-like growth factor-I (IGF-I) is a potential modulator of responses to a variety of immunological challenges. Previous studies have suggested that specific IGF-I receptors are present on peripheral blood leukocytes, including polymorphonuclear

Hypergravity signal transduction in HeLa cells with concomitant phosphorylation of proteins immunoprecipitated with anti-microtubule-associated protein antibodies
Autor: Atsushige Sato, Peggy A. Whitson, Nitza M. Cintron, Yasuhiro Kumei
Publikováno v: Experimental cell research. 192(2)
We have shown that hypergravity (35g) stimulates production of inositol 1,4,5-trisphosphate (IP3) and decreases adenosine 3',5'-cyclic monophosphate (cAMP) levels in HeLa cells. IP3 production rapidly increased 1.5- and 2.1-fold greater (P less than

Long-Term Storage of Salivary Cortisol Samples at Room Temperature
Autor: Peggy A. Whitson, Nitza M. Cintron, Yu-Ming Chen
Publikováno v: Clinical Chemistry. 38:304-304
Collection of saliva samples for the measurement of cortisol during space flights provides a simple technique for studying changes in adrenal function due microgravity. In the present work, several methods for preserving saliva cortisol at room tempe
