Caracterização topológica dos motivos das redes biológicas integradas da Escherichia coli e da Saccharomyces cerevisiae

The reducionism method has helped in the clari cation of functioning of many biological process. However, such process are extremely complex and have emergent properties that can not be explained or even predicted by reducionism methods. To overcome these limits, researchers have been used a set of methods known as systems biology, a new area of biology aiming to understand the interactions between the multiple components of biological processes. These interactions can be represented by a mathematical object called graph or network, where the interacting elements are represented by a vertex and the interactions by edges that connect a pair of vertexes. Into graphs it is possible to nd subgraphs, occurring in complex networks at numbers that are signi cantly higher than those in randomized networks, they are de ned as motifs. As motifs in biological networks may represent the structural units of biological processess, their detection is important. Therefore, the aim of this present work was detect, count and classify motifs present in biological integrated networks of bacteria Escherichia coli and yeast Saccharomyces cere- visiae. For this purpose, we implemented codes in MathematicaR and Python environments for detecting, counting and classifying motifs in these networks. The composition and types of motifs detected in these integrated networks indicate that such networks are organized in three main bridged modules composed by motifs in which edges are all the same type. The connecting bridges are composed by motifs in which the types of edges are diferent

Perfil de ácidos graxos em batatas Chips comercializadas em são José do Rio Preto - Brasil

The objective this study was to evaluate the fatty acids profile of samples of chips potato marketed in the city of São Jose do Rio Preto-SP. We collected samples of 10 brands of chips potato, obtained from 3 different batches. The fatty acids profile was obtained by gas chromatography, with peak identified by retention times with standards of methyl esters and the results calculated and expressed as g/100g of the sample. The fatty acids profile in chips potatoes from different brands were on average 39.22% for saturated fatty acids, 39.64% for monounsaturated, 18.60% for polyunsaturated and 2.43% for trans fatty acids.

Capacidade antioxidante e estabilidade oxidativa de Gengiber officinale

The main objectives of this work were to evaluate the antioxidant activity and to determine of an ethanolic ginger extract total phenolic compounds concentration, as well as verifying its behavior by means of the oxidative stability, when added to refined soybean oil in concentrations of 0, 500, 1000, 1500, 2000 and 2500 mg/kg. The maximum antioxidant activity and EC50, concentration of the extract to achieve 50% of the antioxidant activity, value determined by free radical DPPH method were 79.1% and 42.6 g/mL, respectively. The total phenolic compounds concentration, determined to Folin-Ciocalteu method, was 251 mg/g. The induction period of the samples increased according to the augment of the extract concentration in the oil when evaluated using oxidative stability through the Rancimat equipament. It was possible to conclude that the ginger extracts possess effective action against the lipid oxidation and can be applied in foods as natural antioxidant.

Compostos bioativos benéficos presentes em castanhas e nozes

Epidemiological studies have shown an inverse relationship between nuts, including walnuts, intakes and chronic diseases such as cardiovascular diseases and cancers. The nuts contain phenolics compounds and flavonoids and are rich in tocopherol, phytosterols, and squalene. They are sources of carbohydrates, essential fatty acids and minerals. Since walnuts contain high levels of n-3 fatty acids and low unsaturated fatty acids, high levels of vitamin E, pholyphenols, flavonoids, arginine and fiber. The compounds possible beneficial effects are due to their antioxidant and antiproliferative activities, which are linked to a reduced risk for developing atherosclerosis and cancer. In recent years, the consumers have been showing an increased interest in nuts and walnuts because of their nutritional qualities and their potential beneficial effects on people’s health This review aims to describe the importance of beneficial bioactive compounds present in nuts and walnuts.

Cogumelos: compostos biativos e propriedades antioxidantes

This study presents a literature review which shows the nutritional, medicinal and antioxidant importance of mushrooms. In this research, the main antioxidant compounds of mushrooms, such as phenolic acids, flavonoids and tocopherols, as well as their mechanisms of action were described. The main in vitro methods used for evaluation of the antioxidant activity of these compounds were approached. The influences from the solvent polarity and the kind of extraction in the acquisition of the antioxidant compounds were also discussed. It was possible to conclude that mushrooms are a source of carbohydrates, proteins and minerals, thus presenting nutritional properties. The functional and medicinal properties are attributed to glucans, besides being excellent sources of natural antioxidants. Regarding the extraction process, it was noticed that the solvent polarity used in the extraction process is determinant in the obtainment of antioxidant compounds.

Estudo radiográfico de terceiros molares inferiores retidos e parcialmente irrompidos e revisão de literatuda

Introduction: Pathology associated with retained or partially erupted teeth are common in the general population. Objective: the aim was to evaluate the measurement of pericoronal space of retained third molars and partially erupted teeth in panoramic radiographs. Method: a retrospective study was carried on on the frequency of tooth retention and the problems it can cause in 107 radiographs of patients where the width was measured to verify the presence or absence of diseases associated with the involved teeth. Results: in the 107 panoramic radiographs analyzed the most frequent measurement was of 1.0 mm with 32.71% of cases followed by 2.0 mm with 29.91% of cases. Conclusion: The measurement of the pericoronal sapce of retained third molars and partially retained through its greatest width is in a practical and effective technique for application in routine clinical practice, which suggests the presence or absence of eraly odontogenic pathology

Nível de satisfação dos pacientes edêntulos reabilitados com prótese total na faculdade de odontologia de Adamantina FAI

The population’s life expectancy is growing every year. This fact highlights the importance of the elderly for the dentistry. The oral cavity quality has great influence on quality of life at both the biological and the psychological and social factors by maintaining a self-esteem, self-expression, communication and satisfactory facial aesthetics. Unfortunately, the number of edentulous elderly population is also high, which may create problems to their social life. Therefore, the objective of this study was to demonstrate and evaluate the difficulties of treating edentulous patients, comparing data prior to treatment to post data after treatment by complete dentures made to the patients undergoing oral rehabilitation in the Dental Clinic of the Faculty of Dentistry of Adamantina – FAI. For this study, questionnaires were filled in the form of answers developed alternative focused on the degree of patient satisfaction, the current situation of occlusion, and outcome of treatment. The results showed that 96% of patients were satisfied with the results obtained in the treatment, all of whom believed that the prosthesis helped them feel better aesthetically and improved self-esteem. By this methodology, it was concluded that the degree of satisfaction was high, but the services provided must be constantly reevaluated, once the elderly population presents a wide labor market for dental professionals and demand level services will certainly increase each year.

Condutas terapêuticas para caninos inclusos

Normally, the last teeth to erupt are the ones which remain impacted or semi-impacted, and that is the case of the canines. This study aimed to report a few options of treatment, aiming at esthetic and functional maintenance of the affected area before a impacted canine, discussing its indications, contraindications, advantages and disadvantages. This study also aims to emphasize the accessibility the patient would have in case his/her option were one of the approached ways of treatment. In order to identify the studies included or analyzed in this review, a detailed search strategy was performed for the database used: Pubmed, Bireme, Scielo, Cochrane, and Dentistry Oral Science up to 2011. We used non-erupted teeth, canine, and therapeutics as descriptors. The criteria of inclusion were clinical and review articles that approached the theme. Through this review, it was found that the surgeon dentist’s lack of technical and scientific knowledge and the financial impossibility of most population are some hindrances for the establishment of the right planning for the impacted canine.
