VENTROMEDIAL HYPOTHALAMIC NUCLEI AND FEEDING BEHAVIOR
The role of the ventromedial nuclei of the hypothalamus (VMN) in food behavior was studied in adult male rats, allocated in 3 groups: control, sham and lesioned. Electrolytic lesions were induced stereotaxically (1.2 mA, 15 sec). Results revealed a significant decrease (p<O.05) in body weight (BW) and food intake (FI) in the order of lesioned <sham <control during the fIrst week. However, ...
متن کاملSpecial Subgroups of Gyrogroups: Commutators, Nuclei and Radical
A gyrogroup is a nonassociative group-like structure modelled on the space of relativistically admissible velocities with a binary operation given by Einstein's velocity addition law. In this article, we present a few of groups sitting inside a gyrogroup G, including the commutator subgyrogroup, the left nucleus, and the radical of G. The normal closure of the commutator subgyr...
متن کاملSCATTERING OF 344SMeV “*C IONS ON “B, ‘*C, *‘Al, %Ni, wZr AND lwAu NUCLEI
A survey of the elastic scattering of *‘C ions at 344.5 MeV has been made by measuring angular distributions for targets of “B, “C, *‘Ai, ‘sNi, “Zr and 19’Au nuclei. The data were analyzed using two versions of the opticaf model: (a) a potential with Woods-Saxon form for both the real and imaginary part, (b) a folded potential for the real part based on the densityand energydependent DDM3Y inte...
متن کامل1 Sungrazing comets : Properties of nuclei and in - situ detectability of cometary ions at 1 AU
A one dimensional sublimation model for cometary nuclei is used to derive size limits for the nuclei of sungrazing comets, and to estimate oxygen ion fluxes at 1 AU from their evaporation. Given that none of the ≈ 300 sungrazers detected by the SOlar and Heliospheric Observatory (SOHO) was observed after disappearing behind the sun, and that small nuclei with a radius of ≈ 3.5 m could be observ...
متن کاملThe active site of staphylococcal nuclease: paramagnetic relaxation of bound nucleotide inhibitor nuclei by lanthanide ions.
The structure of 3',5'-thymidine diphosphate bound in the active site of staphylococcal nuclease (EC 3.1.4.7) was studied by measuring the relaxation rate enhancement of substrate analog nuclei by a paramagnetic metal ion. The lanthanide ion, Gd(III), was substituted for Ca(II) in the formation of the ternary complex of nuclease-Gd(III)-3',5'-thymidine diphosphate. Measurements were made of the...
