1. Cytotaxonomy of Dipetalogaster maxima Uhler, 1894 (Hemiptera, Reduviidae, Triatominae)
Resumo A tribo Triatomini consiste em dez gêneros e é considerada uma das tribos mais importantes do ponto de vista epidemiológico. O gênero Dipetalogaster Usinger, 1939 é composto apenas pela espécie Dipetalogaster maxima Uhler, 1894. Este triatomíneo é exclusivo do México e é um vetor potencial da doença de Chagas. Além da importância epidemio

2. Yersinia pestis detection by loop-mediated isothermal amplification combined with magnetic bead capture of DNA
ABSTRACT We developed a loop-mediated isothermal amplification (LAMP) assay for the detection of Y. pestis by targeting the 3a sequence on chromosome. All 11 species of the genus Yersinia were used to evaluate the specificity of LAMP and PCR, demonstrating that the primers had a high level of specificity. The sensitivity of LAMP or PCR was 2.3 or 23 CFU for

3. Cytogenetics and Molecular Genetic Analysis of Chimerism in Marmosets (Callithrix: Primates)
ABSTRACT The birth of fraternal twins is a characteristic frequently observed in callitrichids. Cytogenetic studies have demonstrated hematopoietic chimerism in marmosets with the occurrence of two cell lines 2n=46,XX/46,XY in females and males co-twins, without phenotypic changes. Amplification by PCR have also been used to verify the presence of the SRY ge

4. Description of the karyotypes of Stejneger's beaked whale (Mesoplodon stejnegeri) and Hubbs’ beaked whale (M. carlhubbsi)
Abstract The genus Mesoplodon (Cetacea: Odontoceti: Ziphiidae) is one of the few cetacean genera with the karyotype 2n = 42. The 2n = 42 karyotype of M. europaeus and M. carlhubbsi is largely consistent with the general cetacean karyotype 2n = 44, although other 2n = 42 karyotypes do not exhibit clear homologies with the general cetacean karyotype. Therefore

5. Análisis del cariotipo del híbrido natural Aloe x spinosissima y de sus parentales Aloe arborescens y Aloe humilis, mediante bandeo cromosómico C, CMA y DAPI
Abstract The karyotype of three species of Aloe was studied with C-Giemsa, CMA (Chromomycin A3) and DAPI (4'-6-diamino-2.fenildol) chromosome banding in order to make contributions in their cariomorfometría, location, size studied bands, and discuss cytogenetic evidence of hybrid origin reported in A. x spinossisima. The entities studied have a 2n = 2x = 14

6. Mitochondrial and Y chromosome genetic diversity in the Portuguese Lidia bovine breed
ABSTRACT A total of 80 samples were collected to analyze the mitochondrial DNA (mtDNA) and Y chromosome genetic diversity of two main Portuguese Lidia bovine populations and clarify their genetic relationships with Spanish Lidia lineages. A 521-bp D-loop fragment was sequenced in 40 animals belonging to four herds (three Brava dos Açores and one Casta Portu

8. Ropinirole alters gene expression profiles in SH-SY5Y cells: a whole genome microarray study
Ropinirole (ROP) is a dopamine agonist that has been used as therapy for Parkinson's disease. In the present study, we aimed to detect whether gene expression was modulated by ROP in SH-SY5Y cells. SH-SY5Y cell lines were treated with 10 µM ROP for 2 h, after which total RNA was extracted for whole genome analysis. Gene expression profiling revealed that 11

9. X1X1X2X2/X1X2Y sex chromosome systems in the Neotropical Gymnotiformes electric fish of the genus Brachyhypopomus
Several types of sex chromosome systems have been recorded among Gymnotiformes, including male and female heterogamety, simple and multiple sex chromosomes, and different mechanisms of origin and evolution. The X1X1X2X2/X1X2Y systems identified in three species of this order are considered homoplasic for the group. In the genus Brachyhypopomus, only B. gaude

10. Inheritance patterns and identification of microsatellite markers linked to the rice blast resistance in BC2F1 population of rice breeding
The BC2F1 population was derived from a cross between rice variety, MR219 (susceptible to blast) and Pongsu Seribu 1 (resistant to blast). The objectives of this research were to know the inheritance pattern of blast resistance and to identify the linked markers associated with blast resistance in BC2F1 population. Sixteen microsatellite markers were found a

11. Chromosomal divergence and evolutionary inferences in Rhodniini based on the chromosomal location of ribosomal genes
In this study, we used fluorescence in situ hybridisation to determine the chromosomal location of 45S rDNA clusters in 10 species of the tribe Rhodniini (Hemiptera: Reduviidae: Triatominae). The results showed striking inter and intraspecific variability, with the location of the rDNA clusters restricted to sex chromosomes with two patterns: either on one

12. A remarkable autosomal heteromorphism in Pseudoryzomys simplex 2n = 56; FN = 54-55 (Rodentia, Sigmodontinae)
Pseudoryzomys simplex, the false rice rat, is a monotypic genus of the Oryzomyini tribe (Sigmodontinae) distributed in part of Bolivia, Paraguay, Argentina and Brazil. Its diploid number has been described as 56 acrocentric chromosomes decreasing in size and no karyotype figure has been depicted. Herein, we present karyotypic data on P. simplex, including ch
