The nucleus paragigantocellularis (PGI) is located in the rostral ventrolateral medulla and has noticeable connections with some other brain nuclei, such as locus ceruleus, nucleus raphe magnus and periaqueductal gray. In rats it is 3 mm in rostrocaudal and 1 mm in mediolateral and 1 mm in the dorsolateral aspect. Anatomically and functionally, PGI has been divided into two subnuclei, retrofaci...

objective(s):leptin is a novel and interesting hormone for anyone trying to lose weight, but its effects on male gonad structure in longitudinal study is unknown. the present study was designed to explore morphometrical changes of mouse testicular tissue after long-term administration of leptin. materials and methods:thirty healthy mature male mice were randomly assigned to either control (n=15...

We present a scattering model for nuclei with similar masses. In this three-body model, the projectile has core+valence structure, whereas target is identical to core nucleus. The wave functions must be symmetrized exchange of cores. This property gives rise non-local potentials, which are computed without approximation. an extension Continuum Discretized Coupled Channel (CDCC) formalism, addit...

background: benzene is one of the important occupational pollutants. there are some reports about the leukemogenic effects related to low-level exposure to benzene. objective: to study the frequency of micronucleus (mn), nucleoplasmic bridge (nb), and nuclear budding (nbud) in the peripheral blood lymphocytes of petrochemical workers with low level exposure to benzene. methods: we enrolled 50 w...
