The correlations of 11 indexes of heart rate variability were examined with pharmacologically determined cardiac vagal tone in 15 normal subjects at supine rest. After sympathetic influences by intravenous propranolol were eliminated, RR interval variability was measured for 10 minutes under controlled respiration (0.25 Hz), and cardiac vagal tone was(More)
The hippocampus is vulnerable to the damaging actions of insults such as transient ischemia and repetitive stimulation, as well as repeated exposure to exogenous glucocorticoids. This study investigated effects of a repeated psychological stressor, restraint, on the CA3 pyramidal neurons which are vulnerable to damage by repetitive stimulation. Repeated(More)
Only a small proportion of the mouse genome is transcribed into mature messenger RNA transcripts. There is an international collaborative effort to identify all full-length mRNA transcripts from the mouse, and to ensure that each is represented in a physical collection of clones. Here we report the manual annotation of 60,770 full-length mouse complementary(More)
When cells exit from mitotic cell division, their sister chromatids lose cohesion and separate to opposite poles of the dividing cell, resulting in equational chromosome segregation. In contrast, the reductional segregation of the first stage of meiotic cell division (meiosis I) requires that sister chromatids remain associated through their centromeres and(More)
We previously showed that intraperitoneal injection of lipopolysaccharide induced cyclooxygenase-2 (COX-2) mRNA in as yet unidentified cells of blood vessels and leptomeninges in the rat brain and proposed a possible role of these cells as the source of prostaglandin E2 in the genesis of fever (Cao et al., Brain Res., 697 (1995) 187-196). In the present(More)
Telencephalin (TLN) is a 130 kd glycoprotein expressed exclusively in neurons of the telencephalon, the most rostral brain segment. In the neurons, TLN is localized to soma-dendritic membrane but not to axonal membrane. In this study, we have cloned cDNA encoding rabbit and mouse TLN. The cDNA-derived primary structure of TLN predicts an integral membrane(More)
Studies were performed in vivo on the dentate gyrus to investigate the possible involvement of Type I and Type II adrenal steroid receptors in the mediation of reported adrenal steroid effects on long-term potentiation, through the use of specific Type I and Type II receptor agonists and antagonists. In adrenalectomized rats, administration of aldosterone,(More)
Using affinity chromatography with the monoclonal antibody 271A6, which binds selectively to telencephalic regions of the rabbit brain, we have purified a telencephalon-specific antigen to apparent homogeneity and characterized it as a membrane glycoprotein. The telencephalon-specific membrane protein (named "telencephalin") has a molecular weight of about(More)
Metabotropic glutamate receptors (mGluRs) consist of eight different subtypes and exert their effects on second messengers and ion channels via G-proteins. The function of individual mGluR subtypes in the CNS, however, largely remains to be clarified. We examined the fear response of freezing after electric shock in wild-type and mGluR7(-/-) knockout(More)
Acute restraint and shaking stress each induced the mRNA for the immediate early gene (IEG), c-fos, within 1 h in locus coeruleus (LC), midbrain raphe nuclei and central gray. Both acute restraint stress and acute shaking stress activated c-fos and zif/268 mRNA in paraventricular nuclei within 1 h. Midbrain A9 and A10 dopaminergic neurons did not show any(More)
