Meningococcal disease is the acute infection caused by Neisseria meningitidis, which has humans as the only natural host. The disease is widespread around the globe and is known for its epidemical potential and high rates of lethality and morbidity. The highest number of cases of the disease is registered in the semi-arid regions of sub-Saharan Africa. In Brazil, it is endemic with occasional outbreaks, epidemics and sporadic cases occurring throughout the year, especially in the winter. The major epidemics of the disease occurred in Brazil in the 70's caused by serogroups A and C. Serogroups B, C and Y represent the majority of cases in Europe, the Americas and Australia. However, there has been a growing increase in serogroup W in some areas. The pathogen transmission happens for respiratory route(droplets) and clinically can lead to meningitis and sepsis(meningococcemia). The treatment is made with antimicrobial and supportive care. For successful prevention, we have some measures like vaccination, chemoprophylaxis and droplets' precautions. In this review, we have described and clarify clinical features of the disease caused by N. meningitidis regarding its relevance for healthcare professionals.

AIM: To establish whether virulence factor genes vacA and cagA are present in Helicobacter pylori (H. pylori) retrieved from gastric mucosa and dental plaque in pa-tients with dyspepsia. METHODS: Cumulative dental plaque specimens and gastric biopsies were submitted to histological exami-nation, rapid urease test and polymerase chain reac-tion (PCR) assays to detect the presence of cagA and vacA ***: Detection of H. pylori from dental plaque and gastric biopsy samples was greater by PCR com-pared to histological examination and the rapid ure-ase test. DNA from H. pylori was detected in 96% of gastric mucosa samples and in 72% of dental plaque samples. Sixty-three (89%) of 71 dental plaque sam-ples that were H. pylori-positive also exhibited identical vacA and cagA genotypes in gastric mucosa. The most common genotype was vacAs1bm1 and cagA positive, either in dental plaque or gastric mucosa. These viru-lent H. pylori isolates were involved in the severity of clinical ***: These pathogenic strains were found simultaneously in dental plaque and gastric mucosa, which suggests that gastric infection is correlated with the presence of H. pylori in the mouth.

Induction and Characterization of Embryogenic Callus in Cotyledons Leaves of Tabebuia roseo-alba

引用

Journal of Agricultural Science and Technology(B) 2012年第8期2卷 950-955页

作者： Jorge Marcelo Padovani Porto patricia Duarte de oliveira Paiva Renato Paiva Eduardo Alves Departament of Biology Federal University of Lavras Lavras 37200-000 Brazil Departament of Agriculture Federal University of Lavras Lavras 37200-000 Brazil Departament of Plant Pathology Federal University of Lavras Lavras 37200-000 Brazil

Seeds from Tabebuia roseo-alba lose viability very fast. Moreover, the seed germination rate is very low, reaching approximately 40%. This study aimed at the in vitro induction of embryogenic callus. This technology allows subsequent plant regeneration as an alternative for the production of T. roseo-alba seedlings. Seeds were germinated in vitro and after 20 days, cotyledonary leaves, hypocotyls and root segments excised from these seedlings were used as explants. They were inoculated on MS medium supplemented with sucrose (30 g/L), agar (5.0 g/L) and different auxins. The effect of 2,4-D, picloram and NAA at concentrations 0.0, 0.5, 1.0, 2.0 and 4.0 mg/L was evaluated. For the analysis of callus with embryogenic characteristics, ultra-structural study by scanning electron microscopy and cytochemical test with carmine were performed. The results showed that the culture medium supplemented with 4 mg/L NAA presented induction of callus with embryogenic characteristics in all explants used, with cotyledonary leaves showing the highest percentage (70% of explants with embryogenic characteristics). The use of 2, 4-D and picloram was efficient for callus formation in different explants, but no embryogenic characteristics were observed. From the ultra-structural analysis of callus with embryogenic characteristics, it was found that cells from different explant sources had isodiametric format. This format is similar to somatic embryos in globular stage. The cytochemical analysis confirmed the presence of pro-embryogenic cells in callus mass. Callus induced from cotyledonary leaves presented 46% positive reaction to carmine acetic.

Strategies for Achieving Sustainable Logging Rate in the Brazilian Amazon Forest

Open Journal of Forestry 2014年第2期4卷 100-105页

作者： Evaldo Munoz Braz patricia Povoa de Mattos Mariana Ferraz oliveira Renato Olivir Basso Embrapa Forestry ColomboBrazil Universidade Federal do Paraná CuritibaBrazil Elabore Projetos e Consultoria Florestal SinopBrazil

Data of increment of the remnant trees after logging, ingrowth and mortality was obtained by assessment before logging and after 6 years, two sites of 50 ha, in Amazon forest. Logging scenarios were simulated to identify the logging rate potential for each studying site, by diameter class projection method. The cycle of 35 years and the logging rate of 30 ***-1 exceed the time required for recovery in the primary forest, in the studied site. The simulation showed that in the studying area, a well-planned logging, with minimum logging damage would be possible to implement an initial cycle of 25 years to the forest to recover 30 ***-1, if 50% of the timber stock were reserved. The forest increment, beyond important factors such as the increase of individual species, is quite dependent on the remnant trees.

Objective: To investigate the effects of Agave sisalana(A. sisalana) extract on Aedes aegypti(Ae. aegypti) primary cell ***: Cells of Ae. aegypti were exposed to different concentrations of A. sisalana crude extract(0.18–6.00 mg/m L) for 24 h. Then, the cells were labeled with propidium iodide and subjected to fluorescence microscopy to verify cell viability. In addition, nitric oxide production was ***: Results showed that cells exposed to 6 mg/m L of the crude extract presented a greater percentage of death when compared to control(73.8% ± 9.6% vs. 34.6% ± 9.6%).Furthermore, there was an increase in the nitric oxide production in cells exposed to 6 mg/m L of A. sisalana crude extract [(0.81 ± 0.08) mmol/L] compared to control group[(0.41 ± 0.18) mmol/L].Conclusions: The results show that A. sisalana is cytotoxic to Ae. aegypti and may be used as raw material for new eco-friendly and inexpensive insecticides, since sisal industry discards the liquid waste for the extraction of plant fiber.
