Intrathecal bombesin-induced inhibition of gastrointestinal transit: requirement for an intact pituitary-adrenal axis
(Elsevier, 1986-05)
The role of the pituitary-adrenal axis in the inhibition of gastrointestinal transit caused by intrathecal administration of bombesin was examined. Bombesin (0.3-10 [mu]g) slowed transit by this route in a dose-related ...
Kinetic comparisons of amniotic fluid inactive renin and renal renin using synthetic and human renin substrates
(Elsevier, 1986-12)
Inactive renin has been isolated from pooled amniotic fluid and purified ~642-fold. Prior to activation the isolates has ~4% of the activity found after activation. The observation is similar to that reported for inactive ...
Detection of electrophoretically silent mutations by immobilized pH gradients
(Elsevier, 1986)
The detection of neutral amino acid mutants, by isoelectric focusing in immobilized pH gradients (IPGs), is exemplified by the separation of hemoglobin (Hb) Beirut (126[beta] Val --> Ala) from Hb A in a shallow pH 7.2-7.6 ...
Excited state spectroscopy of para di-substituted benzenes in a supersonic beam using resonant two photon ionization
(Elsevier, 1986)
Excited state vibronic spectra of p-aminophenol, p-cresol, p-fluoroaniline, p-fluorophenol, hydroquinone and p-toluidine have been obtained using resonant two photon ionization supersonic beam mass spectrometry. Despite ...
Intramolecular azide-diene cycloadditions. An approach to fused bicyclic 3-pyrrolines based on a one-pot nitrene-diene cycloaddition equivalent.
(Elsevier, 1986)
Cyclization of heterosubstituted [omega]-azidodienes 11 provides fused bicyclic 3-pyrrolines 12 in one operation. These pyrrolines are potentially useful intermediates for natural products synthesis, as illustrated by ...
Neuroendocrine effects of l -tryptophan and dexamethasone
(Springer-Verlag, 1986-05)
An infusion of l -tryptophan was administered twice to five healthy male volunteers, once after pretreatment with dexamethasone 1 mg the previous evening and once after no dexamethasone. Cortisol, prolactin, and growth ...
Evaluation of plasma 3-methoxy-4-hydroxyphenylglycol
(Elsevier, 1986)
A high-performance liquid chromatographic (HPLC) assay suitable for the evaluation of 3-methoxy-4-hydroxyphenylglycol (MHPG) in 1-ml aliquots of plasma is presented. Preparatory steps include extraction into ethyl acetate ...
The preferential release of beta-endorphin from the anterior pituitary lobe by Corticotropin Releasing Factor (CRF)
(Elsevier, 1986)
Although a number of investigators have shown that release of ACTH is accompanied by the release of Beta-endorphin ([beta]-End) and Beta-lipotropin ([beta]-LPH), the proportion of the latter two peptides released with ...
Thermophysics of metal alkanoates VI. Heat capacities and thermodynamic properties of lithium n-pentanoate and n-heptanoate
(Elsevier, 1986-12)
The adiabatic calorimetric study (at 5 to 350 K) of lithium n-pentanoate and n-heptanoate proved that solid-state transitions occur at Ttrs/K = 209.31 and 319.06 in the former salt, and at Ttrs/K = 317.08 in the latter ...
Isoelectric focusing of proteins in rewetted ultrathin polyacrylamide gel layers
(Elsevier, 1986-12)
Ultrathin layers of polyacrylamide gel bound to glass can be washed, air-dried, and stored for at least 1 year before rewetting in ampholyte solutions for isoelectric focusing. Short-term drying affects neither fluorescent ...
