Progesterone modulation of gonadotropin secretion by dispersed rat pituitary cells in culture. IV. Follicle-stimulating hormone synthesis and release
(Elsevier, 1993-02)
Estradiol-treated, rat pituitary cells were studied to examine the effects of progesterone (P) on follicle-stimulating hormone (FSH) synthesis and secretion. Progesterone was administered prior to or concurrent with 3 h ...
Whole skeletal muscle transplantation: Mechanisms responsible for functional deficits
(Wiley Subscription Services, Inc., A Wiley Company, 1994-04-05)
One aspect of tissue engineering of skeletal muscle involves the transposition and transplantation of whole muscles to treat muscles damaged by injury or disease. The transposition of whole muscles has been used for many ...
Bioactive follicle-stimulating hormone
(Elsevier, 1991)
Specific and sensitive in vitro bioassays suitable for measurement of follicle-stimulating hormone (FSH) in small quantities of serum and urine have recently been validated. Comparisons of bioassay (B-FSH) potencies with ...
Metabolic studies in a mouse model of hepatorenal tyrosinemia: Absence of perinatal abnormalities
(Elsevier, 1992-08-31)
SummaryRadiation induced chromosomal deletions at the albino locus in the mouse, lethal when homozygous, cause abnormalities of expression of several unlinked liver specific genes. Recently, the gene encoding FAH was shown ...
Cardiopulmonary-cerebral resuscitation with 100% oxygen exacerbates neurological dysfunction following nine minutes of normothermic cardiac arrest in dogs
(Elsevier, 1994-03)
This study investigated the effects of normoxic (FIO2 = 0.21), hyperoxic (FIO2 = 1.0), and hyperoxic (FIO2 = 1.0) plus antioxidant pretreatment (tirilizad mesylate) resuscitation on neurologic outcome following 9 min of ...
Variability of laser-evoked potentials: attention, arousal and lateralized differences
(Elsevier, 1993)
We recorded laser-evoked potentials (LEPs) from 20 normal subjects by stimulating the skin with pulses from an infrared CO2 laser. The conduction velocity of the peripheral afferent fibers mediating the LEPs averaged 14.9 ...
Relationship between structure and function of neurons in the rat rostral nucleus tractus solitarii
(Wiley Subscription Services, Inc., A Wiley Company, 1994-06-01)
To investigate the relationship between the structure and function of neurons in the rostral (gustatory) nucleus tractus solitarii (rNTS), we analyzed the morphological and biophysical properties of rNTS neurons by performing ...
Secretagogue-induced Ca2+ oscillations in isolated canine gastric chief cells
(Elsevier, 1991-01-31)
Agonist-induced changes in cytoplasmic free Ca2+ concentration (|Ca2+|i) of isolated canine gastric chief cells were evaluated by microspectrofluorometry of superfused fura-2 loaded cells. Application of high concentrations ...
Activation of phosphatidylinositol-3 kinase by nerve growth factor involves indirect coupling of the trk proto-oncogene with src homology 2 domains
(Elsevier, 1992-10)
Growth factor receptor tyrosine kinases can form stable associations with intracellular proteins that contain src homology (SH) 2 domains, including the p85 regulatory subunit of phosphatidylinositol (Pl)-3 kinase. The ...
[beta]-Hydroxybutyrate and response to hypoxia in the ground squirrel, Spermophilus tridecimlineatus
(Elsevier, 1990)
1. 1. Previous studies have suggested that elevated ketone levels are associated with increased survival time in rodents exposed to hypoxia. In this study the association between whole blood BHB ([beta]-hydroxybutyrate) ...
