Abstract:

The fruit production for export is an economically significant activity in the Valley of S?o Francisco River, especially in the irrigated lands of Petrolina-PE/Juazeiro-BA, Brazil. The development of new genetic material most suitable to the tropical climate and the demands of the consumer market have led to the selection of new seedless grapes cultivars. In this case, the use of the embryo rescue technique has produced satisfactory results for obtaining such materials, especially in the semiarid region. This study aimed to evaluate the in vitro development of intraspecific hybrids of grapevine (Vitis vinifera L.), derived from the rescue of immature embryos resultant from the crossing of “Superior Seedless” and “Thompson Seedless” Brazilian clones. To establish and develop the cultivation, the culture media was supplemented with 30 g/L sucrose, 0.1 g/L myo-inositol, 0.002 g/L glycine, 0.1 mg/L indoleacetic acid (IAA), 6.5 g/L of agar, adjusted pH to 5.7. The experiment was evaluated after 90 days. The variables measured were: number of nodes, number of leaves, plant height (cm), number of roots and length (cm) of the root system and internodes. The period of 60 days of in vitro culture of ovules resulted in the highest values of embryos (about 50%), as well as better characterized developmental stages with higher germination (47.3%). The three types of hybrid grapes evaluated in micropropagation showed very similar values of the measured parameters, even having originated from embryos of different developmental stages.

Abstract:

To assess the prevalence, the antimicrobials resistance and to identify risk factors of nasopharyngeal colonization by Streptococcus pneumoniae in children with sickle cell disease (SCD) using prophylactic penicillin and immunized with 7-valent pneumococcal conjugate vaccine. A total of 424 swabs were collected from the nasopharynx in 216 children with SCD and 109 samples from the control group, both from 2 to 60 months age range. Isolation and identification of pneumococci followed standard procedures. Minimum inhibitory concentration (MIC) for penicillin was determined by the E-test method. Prevalence of nasopharyngeal colonization by pneumococci in children with SCD was 17%, and 11% in the control group. The risk factors for increased colonization in children with SCD were the presence of more than five people at home, daycare/school attendance and low prophylaxis compliance. The prevalence of strains with penicillin resistance was 57.5% in patients with SCD and 25% in the control group. Conclusions: Prevalence of pneumococci nasopharyngeal colonization was similar among the study groups. Prophylactic use of penicillin may have increased the prevalence of resistant strains. The vaccine did not decrease the colonization with penicillin resistant strains.

Abstract: Polycyclic aromatic hydrocarbons (PAHs) constitute a group of priority pollutants which are present at high concentrations in the soils of many industrial contaminated sites. Pollution by these compounds may stimulate growth of organisms able to live in these environments causing changes in the structure of the microbial community due to some cooperative process of metabolization of toxic compounds. A long-term PAH-contaminated soil was stored for several years and used to analyze the native microbiota regarding their ability to grow on pyrene, benzo[a]pyrene, as well as in mixtures of LMW- and HMW-PAHs. Molecular profiles of the microbial community was assessed by PCR-DGGE of 16S rRNA gene, and the number of bands observed in DGGE analyses was interpreted as dominant microbial members into the bacterial community. Results of PAH-contaminated soil microorganisms showed different profiles in the degradative dynamics when some nutrients were added. Predominant species may play a significative role while growing and surviving on PAHs, and some other metabolically active species have emerged to interact themselves in a cooperative catabolism of PAHs. Os hidrocarbonetos poliaromáticos (HPAs) s o considerados poluentes prioritários presentes em expressiva concentra o no solo contaminado com derivados de petróleo. A polui o por esses compostos estimula o crescimento de microrganismos capazes de sobreviverem nestes ambientes contaminados, causando altera es na estrutura da comunidade microbiana do solo pelo processo de coopera o metabólica entre as popula es. Um solo contaminado por um longo período de tempo foi coletado de uma área industrial (Port Melbourne, Austrália) e utilizado para análise da capacidade da comunidade microbiana em crescer em HPAs isolados e/ou em misturas como únicas fontes de carbono e energia. Os perfis moleculares foram obtidos por PCR-DGGE do fragmento da subunidade 16S do DNA ribossomal, sendo o número de bandas presentes nos géis de eletroforese interpretado como popula es dominantes dentro da comunidade do solo. Resultados demonstraram diferentes perfis quando vitaminas e micronutrientes fizeram parte do meio líquido de crescimento da microbiota, além da presen a dos HPAs. As espécies predominantes podem ter papel significativo na degrada o desses compostos no solo a ser remediado, enquanto sobrevivem e interagem com outras popula es por meio de mecanismos de catabolismo cooperativo.

Abstract: Hemicellulose consists of non-cellulosic polysaccharides, with xylans and mannans as their main examples. In nature, xylan can be first degraded to xylooligosaccharides and finally to xylose by certain microorganisms. White-rot fungi basidiomycetes Pleurotus sp. BCCB068 and Pleurotus tailandia were used to degrade oat-spelts xylan under submerged fermentation for a period of 40 days. The study obtained activities of endo-1,4-β-xylanase and β-xylosidase and determination of xylan products by degradation. The fungi reached significant levels of xylan degradation by Pleurotus sp. BCCB068 (75.1%) and P. tailandia (73.4%), following formations of xylooligosaccharides and sugar monomers. These Pleurotus strains proved to be a feasible alternative for biotechnological processes related to degradation of hemicellulose sources.

Abstract: Autism is an infantile disorder of development characterized by deficits in social interaction, communication and unusual and repetitive behavior. Diagnosis is essentially grounded on behavioral tests and there is no pharmacological specific treatment, treatment is merely symptomatic. The aim of this study is to demonstrate the effect of homeopathic remedies on the cognitive and motor development in children with infantile autism. It is presented the evolution of 7 out of 30 children that already were evaluated twice with Psychoeducational Profile Revised (PEP-R), the first was performed before and the second 4-10 months after the onset of homeopathic treatment. Remedies were selected according to similarity between pathogenetic and repertory data and the general symptoms of autism, as well as specific individualization of symptoms in each case, and included organotherapics chosen according to studies related to the brain areas affected by autism. Results showed a positive interference of homeopathic treatment on development and behavior. These results encourage us to continue the study with a larger number of patients.

Abstract: deleterious phases precipitation in superduplex stainless steels is the main concern in fabrication by welding and hot forming of this class of material. sigma, chi and secondary austenite phases are considered deleterious phases because they produce negative effects on corrosion resistance. besides, sigma and chi phases also promote strong decrease of toughness. in the present work, the precipitations of sigma, chi and secondary austenite under aging in the 800-950 °c interval were studied in two uns s32750 steels with different grain sizes. the deleterious phases could be quantified by light optical microscopy, with no distinction between them. scanning electron microscopy was used to distinguish the individual phases in various aging conditions. the results elucidate the influence of the aging temperature and grain size on the kinetics precipitation and morphology of deleterious phases. the kinetics of deleterious phases is higher in the fine grained material in the initial stage of aging, but the maximum amount of deleterious phases is higher in the coarse grained steel.

Abstract: the seasonal dynamics of rhipicephalus sanguineus ticks was developed in dogs from a police unit in goiania, goiás, brazil, from july 2001 to july 2002. the study was carried out on seven naturally infested dogs (two english cocker spaniels and five mongrel dogs), with ages between six months and 10 years. every two weeks, the numbers of feeding larvae, nymphs, and adults were determined. dogs showing infestation levels above 500 adult ticks received three acaricide treatments. considering that the treatments had affected the development of some peaking populations of ticks, it was inferred the occurrence of the following peaks: - larvae (four peaks): from august to november, from november to february, from march to may, and from may to july; - nymphs (five peaks): from july to september, from october to december, from december to february, from march to may, and from june to july; - adults (four peaks): from july to october, from october to january, from january to march, and from april to july. the occurrence of these consecutive peaks of activity of each stage of r. sanguineus may indicate that this tick can develop up to four generations per year in goiania. on the other hand, if the acaricide treatment did not interfere with the development of r. sanguineus peaks, more than four peaks of each stage have occurred on the dogs. in this case, it is acceptable to infer that more than one population of r. sanguineus was developing within the kennel concomitantly. the mean numbers of each tick stage was similar in the different seasons. the main attachment sites were located on the neck, chest, forelegs, armpits, ears, between toes and on the head. the number of adult ticks feeding on english cocker spaniel dogs was 1.4 to 11.5 times higher than that feeding on mongrel dogs.

Abstract: Objective: to stablish association between the prevailing paradigms in health care and current nursing practices in Brazil, also their predominant theoretical approaches. Methodology: it's an analytical test based on discussion of theories, concepts and knownledges of some authors on the subject. The research was conducted through online databases, books, theses and dissertations. The inclusion criteria were classic and recent studies that address the theme of this study. Results: the discussion was started by addressing the historical trajectory of care/caring, pointing its changes, its prospects and influence of the current and emerging paradigms, with the focus on nursing care. Conclusion: nursing nowadays is running through several changes, due to the professionals inability to find solutions to the quotidian practical issues. In this context, nursing tries to rescue the essence of human caring as its unifying focus, essential to the practice, although there is awareness that caring does not compose a paradigm in the context of human health experience.
