-
(1987)The ionic mechanisms that may contribute to the neurotoxicity of kainic acid, were studied in a system of rat thin neocortical slices superfused in vitro. Slices superfused for 3 h under control conditions showed an ...
-
(1987)The electronic structure of 1-(2,5-dimethoxy-4-nitrophenyl)-2-aminopropane (DON) was calculated at the CNDO/2 level, and the racemic compound was synthesized and found to be hallucinogenic at doses of 4 mg. DON differs ...
-
(1987)The study of the influence of the age of animals (13 to 53 weeks) on total liver thiobarbituric acid reactive substances (TBAR) content showed an increase which is maximal in rats of 39 weeks of age compared to young animals ...
-
(1987)Slices of human corpora lutea (CL) obtained at varying stages of the luteal phase from 21 women were used to study the effect of hCG on progesterone (P4) production. Slices obtained from mid- and late CL incubated with 10 ...
-
(1987)The level and proportion of lipids and their fatty acid composition were analyzed in highly purified transverse tubule membranes of amphibian skeletal muscle. Tubule membranes show (a) a higher content of lipids, (b) a ...
-
(1987)To determine if human XX maleness results from an abnormal chromosomal X-Y interchange, we studied the inheritance of the paternal pseudoautosomal region in nine patients. Those six patients in whom Y-specific DNA was found ...

-
(Cell Press, 2014)Tumors rely on the unfolded protein response (UPR) and angiogenesis to survive the metabolic stress of hypoxia. Karali et al. (2014) revealed that VEGF signaling engages UPR sensors in an unconventional manner that is ...
-
(1986)Tritiated thymidine autoradiography was used to analyze the site, time of origin, and developmental gradients of the specialized lining of the ependymal surface of the third ventricle. Cells destined to form the ependyma ...

-
(1987)RU486, a 19-nor steroid, binds with high affinity to the receptors for progesterone and glucocorticoids, blocking the actions of these hormones on their target tissues. We conducted studies to determine whether RU486 ...

-
(Springer-Verlag, 1987)We have studied the global dynamic behavior of neural-like networks of synchronous threshold elements by writing a master equation as a function of parameter values using statistical methods. Exact results for highly ...
-
(1987)The effect of daily doses of 80 mg/kg (intraperitoneal) of alphamethylparatyrosine, AMPT (inhibitor of tyrosine hydroxylase) on the voluntary consumption of ethanol, water, and solid food was studied in rats of both sexes ...
-
(1987)Large unitary conductance Ca2+-activated K+ channels from smooth muscle membrane were incorporated into phospholipid planar bilayers, and the blockade induced by internally and externally applied Cs+ was characterized. ...
-
(1987)Trypanosoma cruzi was isolated from 98 patients, 59 Triatoma infestans, 51 Triatoma spinolai, and 1 Octodon degus from northern Chile. With few exceptions, stocks originating from domestic hosts were classified, based on ...
-
(1987)Voltage-dependent Ca++-activated K+ channels from rat skeletal muscle were reconstituted into planar lipid bilayers, and the kinetics of block of single channels by Ba++ were studied. The Ba++ association rate varies ...
-
(1987)Kinetoplast DNA was isolated from Chilean Trypanosoma cruzi populations and digested with the restriction endonucleases EcoRI, HinfI, HpaII, MspI, and HaeIII. Three major schizodeme groups were discriminated. There was a ...

(1987)Xenopus laevis oocytes were injected with poly(A)+ mRNA isolated from rat brain and superfused in a medium containing either serotonin, angiotensin II or bradykinin. Applications of serotonin or angiotensin II to injected ...
