(2002)We have previously demonstrated that the release of arachidonic acid (AA) from human chorionic gonadotropin (hCG)-stimulated Leydig cells occurs in a dose- and time-dependent manner. In addition, the amount of AA released ...
-
(Endocrine Society, 2002)The aim of the present study was to assess the impact of treatment with GH with or without LHRH analog (LHRH-A) on bone mineralization of GH-deficient adolescents. We studied 17 pubertal, treatment-naive, GH-deficient ...
-
(2002)During propofol/fentanyl anesthesia, a large percentage of patients have jugular bulb oxygen saturation (Sjo2) <50%. The incidence is less with isoflurane/N2O. We evaluated the effect of N2O on Sjo2 during remifentanil-based ...
-
(2002)An intermittent rapid eye movement (REM) sleep deprivation protocol was applied to determine whether an increase in REM sleep propensity occurs throughout an interval without REM sleep comparable with the spontaneous sleep ...

-
(2001)The mechanism and site of action of Ca2+ at the recombinant murine 5-hydroxytryptamine (5-HT)3A receptor were investigated using whole-cell voltage clamp, radioligand binding and single-cell Ca2+ imaging. Inhibition of the ...
-
