The electrophysiological properties of distinct subpopulations of striatal medium-sized spiny neurons (MSSNs) were compared using enhanced green fluorescent protein as a reporter gene for identification of neurons expressing dopamine D1 and D2 receptor subtypes in mice. Whole-cell patch-clamp recordings in slices revealed that passive membrane properties were similar in D1 and D2 cells. All MSS...

In this note we prove that the sequence (3, d2, d3), where d3 ≥ d2 ≥ 3, is the multidegee of some tame automorphism of C if and only if 3|d2 or d3 ∈ 3N + d2N.

Iodothyronine deiodinases, types I, II, and III (D1, D2, and D3) activities were measured in tissues of fetal rats, at 18 and 21 days of gestation, at several levels of iodine deficiency (ID): mild ID diet (MID) and moderately severe ID, MID + 0.005% perchlorate (MID+P). D2 was present in fetal skin, increased between days 18 and 21, and also in MID and MID+P. In skin, D3 increased during ID at...

Mice lacking dopamine D2 receptors exhibit a significantly decreased agonist-promoted forebrain neocortical D1 receptor activation that occurs without changes in D1 receptor expression levels. This raises the possibility that, in brains of D2 mutants, a substantial portion of D1 receptors are uncoupled from their G protein, a phenomenon known as receptor desensitization. To test this, we examin...

Chimeric dengue serotype 2/West Nile (D2/WN) viruses expressing prM-E of WN NY99 virus in the genetic background of wild-type D2 16681 virus and two candidate D2 PDK-53 vaccine variants (PDK53-E and PDK53-V) were engineered. The viability of the D2/WN viruses required incorporation of the WN virus-specific signal sequence for prM. Introduction of two mutations at M-58 and E-191 in the chimeric ...

We characterized a rice dwarf mutant, ebisu dwarf (d2). It showed the pleiotropic abnormal phenotype similar to that of the rice brassinosteroid (BR)-insensitive mutant, d61. The dwarf phenotype of d2 was rescued by exogenous brassinolide treatment. The accumulation profile of BR intermediates in the d2 mutants confirmed that these plants are deficient in late BR biosynthesis. We cloned the D2 ...

To determine whether the type 2 iodothyronine deiodinase (D2), the principal central nervous system enzyme converting T(4) to biologically active T(3), is regulated in tanycytes by immune activation, D2 activity was measured in the mediobasal hypothalamus (MBH) 4, 12, and 24 h after administration of bacterial lipopolysaccharide (LPS) and compared with D2 levels in the cortex and anterior pitui...

The N/NNE-striking Aravalli Delhi Fold Belt (ADFB) and the E-striking Central Indian Tectonic Zone (CITZ) converge at Godhra-Chhota Udepur (GC) sector, west-central India. Analyses of mesoscale deformation structures metamorphic phase equilibria in basement supracrustal rocks are integrated with geochronological-geochemical data (accompanying article) to address dynamics Early Neoproterozoic CI...

The current treatment for patients with hypothyroidism is levothyroxine (L-T4) along with normalization of serum thyroid-stimulating hormone (TSH). However, normalization of serum TSH with L-T4 monotherapy results in relatively low serum 3,5,3'-triiodothyronine (T3) and high serum thyroxine/T3 (T4/T3) ratio. In the hypothalamus-pituitary dyad as well as the rest of the brain, the majority of T3...
