Abstract: due to the building of the hydroelectric power plant of ilha solteira, in the late 60s, some areas have been deforested and were used as "loan areas". thus, the soils belonging to these locations were subtracted and these areas' physical, chemical and biological properties became inappropriate. this work aimed at evaluating the use of chemical and organic fertilization to improve the degraded subsoil and replanting with mycorrhizal stryphnodendron polyphyllum ("barbatim?o"). the area is located at the experimental station (fepe), unesp/ilha solteira campus, in selvíria - ms. using the design of randomized blocks with four replications of 250 m2 plots (10 x 25 m), 10 treatments were evaluated: control; liming; fertilizing n + p; liming + n + p; n + p + water hyacinth; n + p + sugar cane bagasse; n + p + water hyacinth + sugar cane bagasse; liming + n + p + water hyacinth; liming + n + p + sugar cane bagasse; and liming + n + p + water hyacinth + sugar cane bagasse. chemical characteristics of the subsoil and plant growth were evaluated five times (june, august, november and december 2005, and march of 2006) and the root percent colonization was evaluated in march 2006. after a year the subsoil still remained acidic and of low chemical fertility. the steam diameter and plant height showed increasing results along the period, with the highest values for the treatments that received liming, n + p and organic residues. the percent mycorrhizal colonization and number of spores were positively influenced by the presence of organic residues.

Abstract: following the construction of the hydroelectric power station of solteira island in the late 1960s, some areas were deforested and used as "lending areas". the soil was extracted from these areas, which acquired chemical and biological characteristics far from the ideal. this work aimed to evaluate the use of organic residues as a reconditioner of degraded subsoil and quantify its effects on soil microbial activity and fertility in 'barbatim?o' (stryphnodendron polyphyllum mart.) cultivation. the area is located at the unesp/ ilha solteira campus farm, in selvíria - ms. four sections (repetitions) of 250 m2 (10 x 25 m) were allocated, with 10 treatments for each, as follows: control; liming; fertilizing+n+p; liming+n+p; n+p+water hyacinth; n+p+sugar cane bagasse; n+p+water hyacinth+sugar cane bagasse; liming+n+p+water hyacinth; liming+n+p+sugar cane bagasse and liming+n+p+water hyacinth+sugar cane bagasse. the chemical characteristics of the subsoil were evaluated as well as plant growth, carbon microbial biomass (cmb) and released c-co2 , metabolic quotient (qco2) and microbial quotient (qmic), in 5 subsoil sample collecting times (june, august, november and december, 2005 and march, 2006). the subsoil displayed the same acid and poor nutrient level characteristics after a year. during the experiment, the cmb presented stabilization tendencies and the qco2 and qmic decreased in the same period. in all, even below the ideal level, the organic residues showed better results, with small positive differences for water hyacinth. cmb exhibited seasonal variations.

Abstract: Miconia langsdorffii Cogn. (Melastomataceae), Roupala montana Aubl. (Proteaceae), Struthanthus syringifolius (Mart.) (Loranthaceae), and Schefflera vinosa (Cham. & Schltdl.) Frodin (Araliaceae) are plant species from the Brazilian Cerrado whose schistosomicidal potential has not yet been described. The crude extracts, fractions, the triterpenes betulin, oleanolic acid, ursolic acid and the flavonoids quercetin 3-O-β-D-rhamnoside, quercetin 3-O-β-D-glucoside, quercetin 3-O-β-D-glucopyranosyl-(1-2)-α-L-rhamnopyranoside and isorhamnetin 3-O-β-D-glucopyranosyl-(1-2)-α-L-rhamnopyranoside were evaluated in vitro against Schistosoma mansoni adult worms and the bioactive n-hexane fractions of the mentioned species were also analyzed by GC-MS. Betulin was able to cause worm death percentage values of 25% after 120 h (at 100 μM), and 25% and 50% after 24 and 120 h (at 200 μM), respectively; besides the flavonoid quercetin 3-O-β-D-rhamnoside promoted 25% of death of the parasites at 100 μM. Farther the flavonoids quercetin 3-O-β-D-glucoside and quercetin 3-O-β-D-rhamnoside at 100 μM exhibited significantly reduction in motor activity, 75% and 87.5%, respectively. Biological results indicated that crude extracts of R. montana, S. vinosa, and M. langsdorffii and some n-hexane and EtOAc fractions of this species were able to induce worm death to some extent. The results suggest that lupane-type triterpenes and flavonoid monoglycosides should be considered for further antiparasites studies.

Abstract: Introduction: Experimental Clinical studies have shown that loss of up to 77.0% of red cell mass can be tolerated as long as it kept the blood volume. However, the blood volume loss of about 34.0% is fatal. The initial attention in patients with bleeding should be given to maintaining blood volume and oxygen transport. Thus, transfusions of allogeneic blood products are associated with an increased risk of morbidity and mortality in cardiac surgery. Some transfusion risk scores have been proposed for cardiac surgery patients. Objective: To review and discuss literature blood transfusion (blood components gradient) in cardiovascular surgery versus polytrauma, gastrointestinal bleeding, and neoplastic diseases. Methods: The model followed for the review was PRISMA. We used the databases as Scielo, Lilacs, Google Scholar, PubMed articles and works of scientific and doctoral theses master. Results: According to the discussion in the literature, the acute bleeding of large volumes is challenging to emergency services. Accordingly, the need to support hemotherapeutics led to the development of protocols for more rational utilization of the monitored blood components. Conclusion: Hemotherapy services have adopted a very dynamic approach to the clinical condition presented by patients, the need for four or more red blood cell units.

Abstract: This is a descriptive study of quantitative approach, developed at the Federal University of Rond?nia located in the Western Amazon. With the aim of analyzing the frequency of visualization of alcoholic content in the Facebook, Instagram and Snapchat, patterns of consumption, reasons that lead them to drink, most used social network and to correlate how often the users are exposed to alcoholic publications, determining if there was an important link between individual drinking practice during the beginning period and six months later. The information was obtained through the application of questionnaires for incoming students of the freshmen semester, in two moments: a period from August to December 2016/2, and, asking the same students again, from March to June 2017/1. 52.8% were males in 2016/2 and 57, 9% of females in 2017/1 with age ranging between 18 and 20 years in both periods. Facebook has proven to be the most used platform among college students. In 2016/2, 63.9% reported seeing alcohol content at Facebook and consuming that substance, comparing to Instagram with 70.4%, and to Snapchat with 74.1%. In 2017/2, academics reporting viewing alcoholic content on Facebook and consuming those alcoholic beverages accounted for 65.8%, compared to Instagram, 74.1% and Snapchat 74.4%. “Celebrating a special occasion with friends” is the most cited reason of why claim to consume alcohol. Therelation between exposure to the alcohol content of the virtual media and the network of friends was found imperceptible to the majority of the students, as they mostly do not consider themselves exposed. Many university students start the graduation already consuming alcoholic substances, which explains why there is no significant change in alcohol consumption between the observed moments, although it was found a relationship between the visualization of alcohol content in social networks and consumption, with greater impact on Snapchat.

Abstract: in the sixties and seventies there was an extraordinary increase in export of horse meat products to europe and japan. this favored an increase in risk of salmonella outspread through those products to human and animal consumer populations. thus, from an exporting company dealing with horse meat located in northeastern brazil (state of pernambuco), 19,238 fragments of more external muscles, salmonella was isolated from 666 samples colleted from 433 animals (horses and donkeys). the serotyping of 745 isolates showed 98 serovars pertaining to 14 serogroups, predominantly classified into subspecies i (98.9%). s. anatum, s. carrau, s. saintpaul, s. agona, and s. typhimurium were the most frequent serovars isolated. preliminary data indicate that the primary causes for the presence of salmonella in the meats probably was contact with feces from slaughtered animals, as well as possible contamination of environments, in view of the absence of human carriers researched in part of the personnel.

Abstract: The “cachaça” is currently one of the fastest growing agro-industrial industries in the country as the drink considered as a symbol of Brazilian nationality. This study aimed to quantify the phenolic compounds, evaluate the antioxidant and antibacterial activity of different samples of aged “cachaça”. The physic-chemical analysis was performed at the Brandy Quality Laboratory of the Federal University of Lavras, and the determination of phenolic compounds was performed by High Performance Liquid Chromatography (HPLC). The antimicrobial activity evaluation was held at the Food Mycology Laboratory through the cavity agar diffusion technique and by steam using the micro-organisms Escherichia coli, Staphylococcus aureus, Salmonella choleraesuis, Listeria monocytogenes and Pseudomonas aeruginosa. The antioxidant activity was evaluated using the DPPH radical sequestering method. The values obtained for the phenolic compounds ranged from 0.41 to 9.69 mg/L, observing the predominance of syringaldehyde, gallic acid and vanillic acid. The phenolic extracts showed a satisfactory antibacterial activity for both Gram-negative and Gram-positive but did not show inhibition against the bacteria Pseudomonas aeruginosa. The antioxidant activity was evidenced by the DPPH test for cachaças tested and the “cachaça” aged in oak barrel showed the highest activity, followed by “cachaça” aged in jequitibá, amburana and balm barrels.
