Occurrence of multiple nucleolus organizer regions and intraspecific karyotype variation in Scaptotrigona xanthotricha Moure (Hymenoptera, Meliponini).

Scaptotrigona xanthotricha has a wide geographic distribution in the Brazilian Atlantic rainforest. One population from southeast and two from northeast Brazil were analyzed and were found to have chromosome polymorphisms. Although the chromosome number 2n = 34 is conserved in this species, karyotypic analysis revealed clear differences between the three populations. Congruent and ubiquitous mu...

Ribosomal Rna in the Nucleolus Organizer

Modeling synchronized calling behavior of Japanese tree frogs.

We experimentally observed synchronized calling behavior of male Japanese tree frogs Hyla japonica; namely, while isolated single frogs called nearly periodically, a pair of interacting frogs called synchronously almost in antiphase or inphase. In this study, we propose two types of phase-oscillator models on different degrees of approximations, which can quantitatively explain the phase and fr...

Activation of Epidermal Growth Factor Receptor (pEGFR) and Expression of Argentophilic Nucleolus Organizer Regions (AgNOR) in Seminomas

Activation of epidermal growth factor receptor (p-EGFR) is one of the triggers in the development of many malignant tumors, and the measurement of Argentophilic Nucleolus Organizer Regions (AgNOR) area is used as a marker of tumor proliferation.
