Abstract: The populational density of Cedrela fissilis Vell. was evaluated. In a secondary forest area in Parque Estadual Lago Azul from Campo Mour o/PR, twenty-four parcels of 20m x 25m were used, totalizing 12,000 m2. Measures of circumference at breast height (CBH) were taken, as well as distinctions between young, adult and old individuals were established. 74 individuals have been sampled: 38 young, 20 adult and 16 old individuals. It was observed that density of Cedrela fissilis population was 61,6 individuals in each hectare represented by: 51,35% of young, 27.02% of adult and 21,61% of old individuals. Results, in accordance with searched literature, are significant and indicate that the secondary forest of the Parque Estadual Lago Azul is passing by a reconstitution phase.

Abstract: A theoretical framework of pharmaceutical services for non-complicated malaria was built based on the Rapid Evaluation Method (WHO). The framework included organization of services and prescribing, among other activities. The study was carried out in 15 primary health facilities in six high-risk municipalities of the Brazilian Amazon. Malaria individuals ≥ 15 years old were approached and data was collected using specific instruments. Data was checked by independent reviewers and fed to a data bank through double-entry. Descriptive variables were analyzed.A copy of the official treatment guideline was found in 80% of the facilities; 67% presented an environment for receiving and prescribing patients. Re-supply of stocks followed a different timeline; no facilities adhered to forecasting methods for stock management. No shortages or expired anti-malarials were observed, but overstock was a common finding. On 86.7% of facilities, the average of good storage practices was 48%. Time between diagnosis and treatment was zero days. Of 601 patients interviewed, 453 were diagnosed for Plasmodium vivax; of these, 99.3% received indications for the first-line scheme. Different therapeutic schemes were given to Plasmodium falciparum patients. Twenty-eight (4.6%) out of 601 were prescribed regimens not listed in the national guideline. Only 5.7% individuals received a prescription or a written instruction of any kind.The results show that while diagnostic procedure is well established and functioning in the Brazilian malaria programme, prescribing is still an activity that is actually not performed. The absence of physicians and poor integration between malaria services and primary health services make for the lack of a prescription or written instruction for malaria patients throughout the Brazilian Amazon. This fact may lead to a great number of problems in rational use and in adherence to medication.Brazil today reports 50% of all malaria cases in the Americas Region and the

Abstract: Red rice is one of the most important weeds of cultivated rice in Brazil. On the other hand, red rice constitutes a collection of genes lost during the cultivated rice domestication process and has a fundamental importance for recovery of promising genic constitutions. This study had the objective to analyze the genetic variability of a colletion of red rice (Oryza sativa L.) ecotypes from Rio Grande do Sul State, Brazil, through isoenzimatic and microsatellite markers. Thirty four accesses from the Seed and Biotechnology Laboratory germplasm bank, at Federal University of Pelotas, were analyzed using six isoenzimatic systems and nineteen microsatellite markers. Twenty-three biochemical and 54 molecular alleles were identified and used to estimate the polymorphism (PIC) and genetic similarity indexes. The analyzed red rice population presents large genetic variability, evidencing the potentiality to map characteristics of interest to seed physiology. Biochemical markers of the isoenzime type and molecular markers of the microsatellite type are efficient to estimate the genetic variability in red rice ecotypes. KEY-WORDS: Oryza sativa; biochemical markers; microsatellite markers; genetic variability. O arroz vermelho é uma das principais espécies daninhas para cultivo de arroz no Brasil.

Abstract: Objective: The aim of this study was to evaluate the osteogenic potential of human umbilical cord blood-derived osteoprogenitor cells and to prove its applicability as a promising candidate for cell-based therapeutics for bone repair. Methods: Primary cultures of human umbilical blood cord adherent cells were expanded in vitro until passage 2 and seeded for osteodifferentiation study. Morphological (light microscopy), cytochemical (Von Kossa’s method), and functional analyses (calcium level, alkaline phosphatase activity, and total protein content in cell culture) were carried out 7, 14, 21, and 28 days after the osteoinduction protocol. Results: The proliferative step showed colony-forming units in 7 days. After osteoinduction, cuboidal cellular morphology similar to osteoblasts at 14 days and mineralization nodules and biochemical changes (increased alkaline phosphatase level and calcium deposits) at 21 days confirmed the osteodifferentiation process. Conclusion: Cell culture of human umbilical blood cord is a reliable technique, constituting itself as an alternative source of osteoprogenitor cells for experimental needs. More animal tests and clinical trials must be carried out to validate its use and to establish quality control of future autologous or allogeneic cell-based therapy aimed at bone repair.
