Preliminary X-ray crystallographic studies of a Lys49-phospholipase A(2) homologue from Bothrops pirajai venom complexed with p-bromophenacyl bromide and alpha-tocopherol inhibitors

PrTX-I, a non-catalytic and myotoxic Lys49-PLA(2) from Bothrops pirajai venom has been crystallized alone and in complex with bromophenacyl bromide (BPB), alpha-tocopherol and alpha-tocopherol acetate inhibitors. These crystals have shown to diffract X-rays between 2.34 and 1.65 angstrom resolution. All complexes crystals are isomorphous and belong to the space group P2(1) whereas native PrTX-I crystals belong to the P3(1)21.

Auditoria em Saúde: justificativas de glosas no setor odontológico

Objective – To collecting data about the main explanations for glosses and demonstrating the percentage of production loss in the odontologic procedures. Methods – It is about an epidemiological study of historical series, retrospective and quantitative, based on the data collection of DATASUS information system and reports realized by the city of Aquidauana/MS audit system from 2001 to 2010. Results – The results show that in this period, 921.300 odontologic procedures were presented as production; being 223.226 (24,2%) individual procedures and 698.074 (75,8%) collective. There were 23.881 (2,6%) glosses, being 10.158 (42,5%) in the collective procedures and 13.723 (57,5%) in the individual ones. The main cause for glosses related to individual procedures was the repetition of procedures for the same patient and the same tooth (42,4%). In the collective activities, it was the non-accomplishment of the oral health collective program (68,9%). There was an increase of loss in the individual procedures going from less than 5% in the period of 2001 to 2007; to 5,8 % in 2008; 8,9% in 2009 and 14,1 % in 2010 and in the collective procedures the loss reached 4% in 2010. Conclusion – It was concluded that the most frequent cause of glosses explanation was the repetition of procedures for the same patient and the same tooth in the individual cases and the non-accomplishment of the oral health collective program in the collective activities. The importance of the audit system as a trust-worthy instrument for the managers in the planning and evaluation of health actions with the intention of guarantee the solution of the serv-ices provided.

Resíduos sólidos no Brasil: contexto, lacunas e tendência

The theme of solid waste is in high evidence today, a fact noted by the recent implementation of the European directive, and in Brazil, by the National Solid Waste Policy. Understanding the impact of this policy on the national scientific production is essential to plan new directions and research trends. Through a bibliometric and scientometric studied, this research analyzed the national and global context of the last 20 years and found areas in which research progressed, as municipal solid waste, and essentials gaps to develop more the national state-of-the-art, as solid waste of transport. So, the results of this study are a plausible tool to justify for further research on this topic.

Variação dimensional de tábuas de Eucalyptus grandis durante alguns níveis de tempo e temperatura de termorretificação

The objective of this study was evaluate the effects of retification® temperatures and times on thickness variation from Eucalyptus grandis timber. Boards from logs of 30-year-old Eucalyptus grandis trees, from São Paulo Forest Institute in Santa Barbara, Brazil, were thermally modified at 180ºC for 2.5 hours, at 200ºC for 3.0 hours and 200ºC for 4.0 hours. The results showed that: (1) the thermally modified wood at 200°C by 3.0 to 4.0 hours showed increased thickness between 0.698 mm and 0.874 mm due to the internal cracks, (2) the thermally modified wood at 180°C by 2.5 hours has a decreased from 0,177 mm in thickness and the absences of internal cracks.
