(1998)We have studied chorionic villi from 38 placentae obtained from spontaneous abortions at 7 to 12 weeks of pregnancy. Samples were separated into four groups: (1) early normal (7-9 weeks of pregnancy, normal karyotype); (2) ...
-
(1998)4F2hc is an almost ubiquitous transmembrane protein in mammalian cells; upon expression in Xenopus laevis oocytes, it induces amino acid transport with characteristics of system y+L. Indirect evidence fostered speculation ...

-
(1997)This study tested the hypothesis that in the llama fetus changes in cerebral blood flow are closely associated with changes in cerebral oxidative metabolism such as occur during transitions between electrocortical states. ...
-
Rapid kinetic studies of SH oxidation-induced calcium release from sarcoplasmic reticulum vesicles (Academic Press Inc., 1997)We studied the kinetics of calcium release induced by SH oxidation in triads isolated from frog and rabbit skeletal muscle by measuring calcium fluxes by a fast filtration method. In both species SH oxidation induced release ...

(1997)The influence of acute ethanol administration on the oxidative stress status of rat brain and liver was assessed by in situ spontaneous organ chemiluminescence (CL). Brain and liver CL was significantly increased after ...
-
(Wiley-Blackwell Publishing Ltd, 1997)Intracellular pH has been shown to be an important physiological parameter in cell cycle control and differentiation, aspects that are central to the spermatogenic process. However, the pH regulatory mechanisms in spermatogenic ...
-
(1998)Selecting effective antisense target sites on a given mRNA molecule constitutes a major problem in antisense therapeutics. By trial-and-error, only 1 in 18 (6%) of antisense oligonucleotides designed to target the primary ...
-
(Springer-Verlag France, 1997)The morphofunctional development of Sertoli cells defines the testicular differentiation. These somatic cells are mostly of mesonephric origin and can be first recognized in 7 week-old embryos altogether with the formation ...
-
(1997)It seemed interesting to determine the incidence of hospitalary entrance caused by non compliance of treatment in cardiovascular and respiratory patients, hospitalized in the Service of Medicine of five hospitals of the ...

(Elsevier USA, 1996)A study of the acceptability of Uniplant, a 12-month single implant of nomegestrol acetate, included 819 women from Africa, Latin America, and China, participating in a clinical trial of Uniplant. A standard, pre-coded ...
-
(1996)Development of tolerance and cross-tolerance after acute administration of the μ agonist morphine and the K agonist U-50,488H was assessed in rats, through recording of a C-fiber-evoked spinal nociceptive reflex. Rats ...
-
(1996)Oral vasodilators have proved to be valuable drugs in the management of systolic or diastolic congestive heart failure. They produce a clinical and hemodynamic relief of preload, afterload or both during the resting state ...
-
(1996)Several types of collagen, including types I, III, IV, V and VI, are produced by bone marrow stromal cells. Current information indicates that changes in collagen production result in profound alterations in the capacity ...
