Karyotypic evolution of ribosomal sites in buffalo subspecies and their crossbreed

Domestic buffaloes are divided into two group based on cytogenetic characteristics and habitats: the “river buffaloes” with 2n = 50 and the “swamp buffaloes”, 2n = 48. Nevertheless, their hybrids are viable, fertile and identified by a 2n = 49. In order to have a better characterization of these different cytotypes of buffaloes, and considering that NOR-bearing chromosomes are involved in the rearrangements responsible for the karyotypic differences, we applied silver staining (Ag-NOR) and performed fluorescent in situ hybridization (FISH) experiments using 18S rDNA as probe. Metaphases were obtained through blood lymphocyte culture of 21 individuals, including river, swamp and hybrid cytotypes. Ag-NOR staining revealed active NORs on six chromosome pairs (3p, 4p, 6, 21, 23, 24) in the river buffaloes, whereas the swamp buffaloes presented only five NOR-bearing pairs (4p, 6, 20, 22, 23). The F1 crossbreed had 11 chromosomes with active NORs, indicating expression of both parental chromosomes. FISH analysis confirmed the numerical divergence identified with Ag-NOR. This result is explained by the loss of the NOR located on chromosome 4p in the river buffalo, which is involved in the tandem fusion with chromosome 9 in this subspecies. A comparison with the ancestral cattle karyotype suggests that the NOR found on the 3p of the river buffalo may have originated from a duplication of ribosomal genes, resulting in the formation of new NOR sites in this subspecies.

O ensino de redação em sites: diálogos em rede

We know that studies on reading and writing take place within the Linguistic for several decades and, with de computer, the language entered the network and this is opening a learning space for writing classes, no more reduced to a classroom but expanded to a universe that has no geographical boundaries, namely de Internet. Our research fits into this context and is part of the project The discourse on writing practices in contemporary Brazilian media: the art making, the pedagogical practice, and the production of meaning to develop discourse analysis on the practice of writing on sites dedicated to teaching and learning of this practice. The main objective of this research is to investigate the relationship between school attendance of redaction - made here as discourse gender, as you know Bakhtin - and the discourse of the sites that constitute our corpus. We set out the hypothesis that the sites are intended for the teaching/learning of writing seeking to create virtually teaching imaginarily conditions similar to those that exist in school attendance of the Portuguese language. We are interested in, therefore, observe, discursively, as the image is created of the interlocutors to which they are intended considering that the enunciators are not in front of those who occupy the place of real students, because they are virtual students. We, too, to know as the gender class manifested itself in those sites, as these sites dialogue with the face-to-face class in relation to ideology, the function of the teacher, the conception of language and writing. The constitution of the corpus was from search tools on the internet. The sites that we analyzed were: alunosonline.com.br, brasilescola.com.br, coladaweb.com.br, guiadoestudante.com.br, infoescola.com.br, mundoeducação.com.br, mundovestibular.com.br, português.com.br, professorjuscelino.com.br and redaçãodissertativa.com.br. The selection was qualitative, considering the...

Relacionamentos amorosos na pós-modernidade: análise das consultas apresentadas em sites de relacionamento amoroso

The contemporary culture is based in a logic of acceleration and shortening of the relationships, a logic that disseminates and lodges in the subjectivity, so as to affect the most varied spheres of life. The purpose of the present work is to examine the conflicts that emerge in love relationships lived in such context. Seventy-four queries submitted by the users of two love-consultancy websites were taken as the object of our analysis. The complaints presented by the users were collated to the paradigms of relationship produced in the contemporary days. It was possible to observe that the modes of subjectification predominant nowadays can be apprehended in the love sphere of the human life and that from those modes derive most of the affective conflicts reported by people who seek advice in those websites. The sentimental hardship of these subjects denounces the ills of our days.

Healing at implant sites prepared conventionally or by means of Sonosurgery (R): an experimental study in dogs

ObjectiveTo compare peri-implant tissue healing at implants installed in sites prepared with conventional drills or a sonic device.Material and methodsIn six Beagle dogs, the mandibular premolars and first molars were extracted bilaterally. After 3 months, full-thickness muco-periosteal flaps were elevated and recipient sites were prepared in both sides of the mandible. In the right side (control), the osteotomies were prepared using conventional drills, while, at the left side (test), a sonic device (Sonosurgery((R))) was used. Two implants were installed in each side of the mandible. After 8weeks of non-submerged healing, biopsies were harvested and ground sections prepared for histological evaluation.ResultsThe time consumed for the osteotomies at the test was more than double compared to the conventional control sites. No statistically significant differences were found for any of the histological variables evaluated for hard and soft tissue dimensions. Although not statistically significant, slightly higher mineralized bone-to-implant contact was found at the test (65.4%) compared to the control (58.1) sites.ConclusionsSimilar healing characteristics in osseointegration and marginal hard tissue remodeling resulted at implants installed into osteotomies prepared with conventional drills or with the sonic instrument (Sonosurgery((R))).

Healing of implants installed in over- or under-prepared sites: an experimental study in dogs

ObjectiveTo study bone healing at implants installed with different insertion torques.Material and methodsIn six Labrador dogs, all mandibular premolars and first molars were extracted. After 4months of healing, flaps were elevated, and two implant sites were prepared at each side of the mandible. In the right side of the mandible, the distal sites were prepared conventionally, while the mesial sites were over-prepared by 0.2mm. As a consequence, a final insertion torque of similar to 30Ncm at the distal and a minimal insertion torque close to 0Ncm at the mesial sites were obtained. In the left sides of the mandible, however, the recipient sites were underprepared by 0.3mm resulting in an insertion torque of 70Ncm at both implants. Cover screws were applied, and flaps sutured to fully submerge the experimental sites. After 4months, the animals were sacrificed and ground sections obtained for histological evaluation.ResultsThe mineralized bone-to-implant contact was in the range of 55.2-62.1%, displaying the highest value at implants with similar to 30Ncm insertion torque and the lowest value at the implant sites with close to 0Ncm insertion torque. No statistically significant differences were revealed. Bone density was in the range of 43.4-54.9%, yielding the highest value at implants with 70Ncm insertion torque and the lowest at the implant sites with close to 0Ncm insertion torque. The difference between the sites of similar to 30Ncm and the corresponding 70Ncm insertion torque reached statistical significance.ConclusionsSimilar amounts of osseointegration were obtained irrespective of the insertion torque applied. Moreover, implants installed in sites with close to 0Ncm insertion torque may properly osseointegrate as well.
