Sugarcane (Saccharum X officinarum): A Reference Study for the Regulation of Genetically Modified Cultivars in Brazil

Global interest in sugarcane has increased significantly in recent years due to its economic impact on sustainable energy production. Sugarcane breeding and better agronomic practices have contributed to a huge increase in sugarcane yield in the last 30 years. Additional increases in sugarcane yield are expected to result from the use of biotechnology tools in the near future. Genetically modified (GM) sugarcane that incorporates genes to increase resistance to biotic and abiotic stresses could play a major role in achieving this goal. However, to bring GM sugarcane to the market, it is necessary to follow a regulatory process that will evaluate the environmental and health impacts of this crop. The regulatory review process is usually accomplished through a comparison of the biology and composition of the GM cultivar and a non-GM counterpart. This review intends to provide information on non-GM sugarcane biology, genetics, breeding, agronomic management, processing, products and byproducts, as well as the current technologies used to develop GM sugarcane, with the aim of assisting regulators in the decision-making process regarding the commercial release of GM sugarcane cultivars. © 2011 The Author(s).

Posterior partially edentulous jaws, planning a rehabilitation with dental implants

To discuss important characteristics of the use of dental implants in posterior quadrants and the rehabilitation planning. An electronic search of English articles was conducted on MEDLINE (PubMed) from 1990 up to the period of March 2014. The key terms were dental implants and posterior jaws, dental implants/treatment planning and posterior maxilla, and dental implants/treatment planning and posterior mandible. No exclusion criteria were used for the initial search. Clinical trials, randomized and non randomized studies, classical and comparative studies, multicenter studies, in vitro and in vivo studies, case reports, longitudinal studies and reviews of the literature were included in this review. One hundred and fifty-two articles met the inclusion criteria of treatment planning of dental implants in posterior jaw and were read in their entirety. The selected articles were categorized with respect to their context on space for restoration, anatomic considerations (bone quantity and density), radiographic techniques, implant selection (number, position, diameter and surface), tilted and pterygoid implants, short implants, occlusal considerations, and success rates of implants placed in the posterior region. The results derived from the review process were described under several different topic headings to give readers a clear overview of the literature. In general, it was observed that the use of dental implants in posterior region requires a careful treatment plan. It is important that the practitioner has knowledge about the theme to evaluate the treatment parameters. The use of implants to restore the posterior arch presents many challenges and requires a detailed treatment planning.

Intervenções com a atividade física em crianças e adolescentes com deficiência intelectual: uma meta-análise

Abstract Intellectual disability is development atypical conditions that involve issues on a number of factors, such as intellectual skills, adaptive behavior, interactions and social roles. Furthermore, they report higher rates of physical inactivity than the general population, as well as participating less and less of regular physical activity, as they grow and age. The participation of people with intellectual disabilities in physical activity programs promotes, benefits of prevention of diseases, particularly cardiovascular, improvement of intellectual and cognitive ability in addition, regular physical activity promotes reduction of body fat. Therefore the aim of this study was to identify through a systematic review, physical activity programs for adults with intellectual disabilities and their extension of the benefits, limitations and recommendations, moreover, the following objectives: to analyze the types of physical activity programs and determine which is the most suitable for adults with intellectual disabilities, and to determine the benefits that physical exercises programs entail for adults with intellectual disabilities. The initial electronic search resulted in 2808 manuscripts. The predetermined exclusion criteria were: review process of the studies involved reading titles, abstracts and full texts checking. After all these phases, eight manuscripts met the inclusion criteria of the review. Articles presented participants aged between 18 and 67 years with mild to moderate intellectual disability. The intervention period was from 2.5 months studies ranged up to 9 months and the weekly frequency was from one to three times a week. The intervention types differ between the articles analyzed, including leisure and recreation activities, combined exercises of strength and muscular endurance, aerobic activities of hiking, with races and exercise bikes, widespread activities and sports specialization, athletics and...

Dançando o ritmo do preconceito: uma análise do estido waacking com o enfoque no sexo masculino

Understanding dance in all its educational aspects, creative and liberating, this of course work completion back motivating information for new studies and reflections. This study did a literature review to contextualize and detail reach the story and how it perpetuates in practice the dance style Waacking, sought the understanding of how the body is inserted in our society, made notes on the Sport Psychology regarding the topic fear and shame, and pledged to address the conflicting issues of gender and sexuality, to then be possible to develop what has been objectified. This study sought to establish whether there are national publications on the Waacking dance style and what their contributions to the Brazilian context, verifying the presence of stereotypes and prejudices to males in it are inserted. As used method, the survey was conducted in online databases having the following sites as a source of scientific academic content to nationwide: Google Scholar (like the filter to search only in Portuguese language - as the focus of the research is to gather national publications); Journals Portal CAPES / MEC; and SciELO - (Scientific Electronic Library Online). The review process took place using the categorization model, which was essential to be able to extract the information that met relevant from the criteria that have been pre-established, thus enabling the completion of this work Completion of course

Amides as cryoprotectants for freezing stallion semen: A review

Stallion semen cryopreservation, despite its impact on the horse industry, is not an established technology. During the last years, a number of modifications have been proposed to the freezing process, however, a large population of stallions still have poor semen quality and fertility after frozen-thawed. Glycerol toxicity could be a reason for the variation on stallion sperm freezability. There are limited publications concerning the use of alternative cryoprotectants for equine sperm. Glycerol is contraceptive for some species and other cryoprotectors, such as amides, have been show to be a good option for freezing semen of these species. Recent reports have shown encouraging data respecting the use of amides as cryoprotectants for stallions, with more remarkable improvements for semen from stallions that freeze poorly when glycerol is used.

Larval development of Apiomithrax violaceus (A. Milne Edwards, 1868) (Decapoda : Brachyura : Majoidea : Pisidae) reared in laboratory conditions, and a review of larval characters of Pisidae

Apiomithrax violaceus (A. Milne Edwards, 1868 ) is a pisid majoid crab occurring in tropical and subtropical coastal waters of the eastern and western South Atlantic. Larval development consists of two zoeal stages and a megalopa. Beginning with the first zoea, the duration of each larval stage at 24degreesC was 3-8 (5+/-1), 3-5 (4+/-0.5) and 9-15 (11+/-2) days, the megalopa and first crab instar appearing 9-11 (10+/-1) and 20-27 (23+/-2) days after hatching, respectively. Larval characters agree with those proposed for the Majoidea, in having nine or more setae on the scaphognathite in the first zoea and well-developed pleopods in the second zoea. However, larvae of A . violaceus do not fit larval pisid features. Zoeal stages differ from most other Pisidae in having lateral spines, a long rostral spine extending beyond the antenna, two spines per telson fork and a dorsolateral process on the third abdominal somite. The megalopa differs in having a spine dorsally on the carapace and on the basial segment of the second pereiopod. Two characters that are potentially unique to Apiomithrax include a zoeal antenna with an exopod that is much longer than the protopod, and a rostral spine that is longer than the dorsal spine. These characters should facilitate the identification of this taxon and could also be useful for phylogenetic studies. A review of larvae of 28 species among 14 genera indicated that there is no apparent single larval character that differentiates the Pisidae, with more limited phylogenetic analyses suggesting that this is a paraphyletic group. Apiomithrax , Eurynolambrus , Pisoides , Rochinia and Scyra have the most divergent morphological characters within the family. The analysis and inclusion of additional taxa is likely to shed more light on the sister-group relationships of the Pisidae. However, based on the extent of morphological interspecific variability of known larvae it is likely that the group, as presently defined by adult morphology, is not monophyletic.

A review of postfeeding larval dispersal in blowflies: implications for forensic entomology

Immature and adult stages of blowflies are one of the primary invertebrate consumers of decomposing animal organic matter. When the food supply is consumed or when the larvae complete their development and migrate prior to the total removal of the larval substrate, they disperse to find adequate places for pupation, a process known as postfeeding larval dispersal. Several important ecological and physiological aspects of this process were studied since the work by Green (Ann Appl Biol 38:475, 1951) 50 years ago. An understanding of postfeeding larval dispersal can be useful for determining the postmortem interval (PMI) of human cadavers in legal medicine, particularly because this interval may be underestimated if older dispersing larvae or those that disperse longer, faster, and deeper are not taken into account. In this article, we review the process of postfeeding larval dispersal and its implications for legal medicine, in particular showing that aspects such as burial behavior and competition among species of blowflies can influence this process and consequently, the estimation of PMI.

Overspinning a nearly extreme charged black hole via a quantum tunneling process

We examine a nearly extreme macroscopic Reissner-Nordstrom black hole in the context of semiclassical gravity. The absorption rate associated with the quantum tunneling process of scalar particles whereby this black hole can acquire enough angular momentum to violate the weak cosmic-censorship conjecture is shown to be nonzero.
