Caracterização da população portadora de tuberculose do município de Américo Brasiliense/SP, no período de 1992 a 2002

Tuberculosis (TB) is a serious public health problem all over the world, which was recognized by the WHO in 1993 as a global emergency because of its very high incidence in the 22 countries that concentrate 80% of TB cases. One of these countries is Brazil, where TB occurrences are well-documented in major cities, but little is known of its spread in rural areas and small towns. Therefore, an epidemiological study was done on medical records of TB sufferers in the rural district and small town of Américo Brasiliense, São Paulo state, from 1992 to 2002, with the aim of improving TB prevention and treatment. The results showed that the incidence of TB peaked in the years of intense migration of rural workers, largely cane-cutters. Among these, the disease attacks mainly the men, in their productive years (20 to 40 years old). The predominant clinical form observed was pulmonary tuberculosis. The treatment abandonment rate was less than 1.8%, while the cure rate was around 90%. The disease detection rate by examination of sputum for acid-fast bacilli was around 60%.

Variação genética para caracteres anatômicos e retração volumétrica e sua correlação com a densidade básica da madeira em uma população base de Eucalyptus camaldulensis Dehn

Eucalyptus camaldulensis has great importance in Brazil because of their phenotypic plasticity for different environmental conditions, as soils, altitudes and rainfall. This study is an investigation of a base population of E. camaldulensis from Australia through a progeny test implanted in Selvíria, MS. The trial was established in a randomized block design, with 25 families and 60 replications of single tree plots. Genetic parameters for anatomic traits and volume shrinkage were estimated, as well as their correlations with wood basic density. No significant differences among progenies were observed for the traits studied. The additive genetic variation coefficient at individual and among progeny levels ranged from low (0.26%) to high (16.98%). The narrow sense heritability at individual and family means levels also ranged from low (0.01) to high (0.87). This indicates that some traits are under strong genetic control and can be improved by selection. In the present situation, in order to attain the highest genetic gains, the sequential selection among and within progeny would be recommended.

Sementes de feijão-caupi (Vigna unguiculata L. (Walp), tratadas com extrato de folhas de nim (Azadirachta indica A. Juss.) avaliação da germinação e da incidência de fungos

This study aimed to evaluate the effect of aqueous extract of neem on germination and fungi incidence on seeds of three cultivars (Serrinha, BR 17 and Maranhão) of cowpea. Neem leaves were dryed, crushed and prepared dilutions of 0.5; 1.0; 2.0, 4.0 g dm -3and control. The fungi incidence was evaluated by the test filter paper and germination according to the Rules for Seeds Testing (Regras para Análise de Sementes). In the three cultivars analyzed, reduction in the incidence of Aspergillus sp and Fusarium sp was observed. In relation to the influence of extracts of neem leaves on seed germination, significant effect of extract in Maranhão cultivar was observed, where all concentrations differed from the control, and propovided a considerable increase in the percentage of normal seedlings. It was concluded that the leaf extract of neem was effective in controlling Aspergillus sp, Fusarium sp , Phoma sp and Macrophomina phaseolina at different concentrations in different cultivars and seed germination was stimulated for the Maranhão cultivar.

Perfusão cerebral e análise individual automatizada utilizando SPECT em uma população com transtorno obsessivo-compulsivo

Objective: To make individual assessments using automated quantification methodology in order to screen for perfusion abnormalities in cerebral SPECT examinations among a sample of subjects with OCD. Methods: Statistical parametric mapping (SPM) was used to compare 26 brain SPECT images from patients with OCD individually with an image bank of 32 normal subjects, using the statistical threshold of p < 0.05 (corrected for multiple comparisons at the level of individual voxels or clusters). The maps were analyzed, and regions presenting voxels that remained above this threshold were sought. results: Six patients from a sample of 26 OCD images showed abnormalities at cluster or voxel level, considering the criteria described above, which represented 23.07%. However, seven images from the normal group of 32 were also indicated as cases of perfusional abnormality, representing 21.8% of the sample. Conclusion: The automated quantification method was not considered to be a useful tool for clinical practice, for analyses complementary to visual inspection.

Fatores de risco da transmissão de zoonoses por costumes da população de Ilha Solteira, Brasil

Objective Determining conditions regarding possible zoonosis transmission risk based on Ilha Solteira-São Paulo citizens' habits aimed at establishing concrete recommendations for the corresponding local authorities to reduce some risk factors. Methods100 focalized interviews were held on Ilha Solteira's urban perimeter during April 2008. The people interviewed were adults who lived or worked in houses in the study area. Results This research found a significant number of cat and/or dog owners who allowed their pets to stay in internal areas of their houses. They did not define a specific place for animals to defecate and/or urinate or did not arrange appropriate final disposal of such waste. Conclusion Local authorities must make greater efforts at educating Ilha Solteira pets' owners and providing them with information and encouraging greater citizen commitment and awareness to improve habits related to caring for pets/animal sand reducing zoonosis transmission risk factors.

Estabelecimento de fungos nematófagos aplicados no campo para o controle dos nematoides-chaves dos citros no Brasil

Monitoring the survival of nematophagous fungi is needed to establish periods of reapplication of formulations of nematophagous fungi to control the citrus nematode in the field. We monitored the survival of fungi: Arthrobotrys robusta, A. oligospora, A. musiformis Dactylella leptospora and Monacrosporium eudermatum in plots treated with 1, 2, 4, 6 liters of the formulation of fungi/plant or witness without the application, during the period of nine months with the first assessment six months after application and the other with intervals of three months after the first evaluation. The fungus D. leptospora was found only in the evaluation of 6 months after treatment application, indicated a short survival time in the soil. However, the isolated A. robusta, A. musiformis and A. oligospora were recovered in all evaluations and especially in plots treated with higher doses of the formulation and witness. Monacrosporium eudermatum was recovered in all experimental periods and even in assessing the witness portion of nine months after application. The fact of the presence of species of Arthrobotrys and M. eudermatum in control plots indicates that native species that were already orchard.

Fungos endofíticos: Uma fonte inexplorada e sustentável de novos e bioativos produtos naturais

Endophytic fungi are a rich source of new and biologically active natural products. They colonize a relatively unexplored ecological habitat and their secondary metabolism is particularly active, presumably due to metabolic interactions with their hosts. In the course of our continuing investigations for new and bioactive compounds from endophytic fungi from brazilian flora Alibertia macrophylla, Caseria sylvestris, Ocotea corymbosa, Cassia spectabilis, Piper aduncum, Cryptocaria mandioccana, Xylopia aromatica and Palicourea marcgravii were investigated. Forty two natural products were isolated and their structures were established on the basis of comprehensive spectral analysis, mainly using 1D and 2D NMR experiments. The compounds were tested in their antifungal, antioxidant, anticholinesterasic and anticancer activities.
