Abstract: Medication-related osteonecrosis of the jaws (MRONJ) is a relatively new disease. MARX reported first cases in 2003. MRONJ relates to oral and parenteral bisphosphonates as well as to the so-called target cancer therapies but the list of medications only grows. Although MRONJ is a relatively rare condition, it can be associated to significant morbidity with feeding limitations and intense pain. More severe cases can lead to potentially life-threatening infections. Every patient initiating bisphosphonate and/or target cancer therapy must visit a dentist before starting medication because preventive measures for MRONJ are much more effective compared to surgical management of the lesions. Surgical resolution can be especially difficult to obtain in the coexistence of certain complication factors like wider bone exposures, history of nitrogen containing bisphosphonates use (mainly zolendronate) and immunodeficiency. Recently, researchers have given attention to laser therapy associated to photosensitive agents as a possible option to management of some MRONJ lesions. Our case report demonstrates the use of photodynamic therapy in a denosumab related lesion in the mandible. It seems that denosumab related lesions are more amenable to treatment and total resolution because of the marked differences between its chemical and metabolic characteristics when compared to bisphosphonates.

Abstract: Em fun o da interferência do milho em outras plantas, objetivou-se verificar a presen a e a concentra o de benzoxazolinona no milho por meio de extra o aquosa obtida de material vegetal das cultivares AG-1051, C-333 e C-435. A massa fresca das amostras foi colocada em água destilada e deixada em repouso durante quatro horas. O extrato foi filtrado e particionado em solventes com diferentes polaridades. O extrato etéreo desidratado foi filtrado, concentrado em evaporador rotatório e levado à estufa. Este foi purificado por cromatografia de camada delgada. Recristalizou-se em hexano, e os cristais obtidos foram submetidos à análise em espectrometria no Infravermelho. As bandas presentes no produto padr o também foram caracterizadas nas amostras das cultivares de milho testadas. As amostras dos extratos foram qualificadas e quantificadas por espectrofotometria de ultravioleta. Pelos resultados, infere-se que a planta de milho possuiem seu metabolismo a benzoxazolinona, na seguinte ordem decrescente: AG-1051 29 mg g-1, C-333 24 mg g-1 e C-435 21 mg g-1 de BOA. Due to the interference of maize on other plants, the presence and concentration of benzoxazolinone in this particular plant (maize) wasdetermined via the aqueous extract of three varieties of maize (AG-1051, C-333 and C-435). The fresh sample material was allowed to stand in distilled water for four hours. The extract was filtered and partitioned with solvents of varying polarities. The dried etherextract was filtered, concentrated on a rotary evaporator and dried in an oven. The residue was purified by thin layer chromatography and recrystallized from hexane. The crystals were analyzed by infrared spectroscopy. The bands present in the spectrum of the referencesubstance were also observed in the spectra of the samples obtained from the three varieties of maize studied. The extract samples were characterized and quantified by UV spectroscopy. The results indicated that the three varieties of maize possessed benzoxazolinone in their metabolism in the decreasing order AG-1051 29 mg g-1 > C-33324 mg g-1 > C-435 21 mg g-1 of BOA.

A urgência do Princípio Responsabilidade em Hans Jonas
José Soares das Chagas
PERI , 2010,
Abstract: O escopo deste artigo é mostrar a necessidade no mundo hodierno de um novo princípio ético, que leve em considera o as conquistas do homem sobre a natureza. Segundo Hans Jonas, todos os sistemas morais da tradi o conceberam o agir dentro dos limites da existência do agente, de maneira que a pergunta pelos efeitos para as gera es futuras n o se constituía como dado importante a ser considerado. O motivo de tal postura era o fato da natureza e a humanidade serem consideradas como inalteráveis: o ser humano cuidaria apenas da convivência com os de sua espécie, enquanto o meio ambiente cuidaria de si mesmo, indiferente e inabalável perante o que lhe faziam. Com o avan o da técnica, o poder transformador e criador ganhou propor es nunca antes imaginada, ao ponto de n o poder mais se pensar a natureza como infensa à atua o do homem sobre ela. Na verdade, este próprio, que sempre teve o ingênio tecnológico como instrumento seu, passou a ser objeto da sua cria o, pondo-a como fim e n o mais como meio. Por este motivo, a a o humana alarga-se em seu campo de atua o, uma vez que possui hoje a for a de eliminar ecossistemas e até mesmo a vida humana sobre a terra. Para este novo continente do agir, faz-se mister uma nova atitude ética diante do mundo, ao que Hans Jonas vai chamar princípio responsabilidade.

Abstract:

Fruits are unarguably one of the main sources of dietary fiber, but are regional Amazonian fruits sources of dietary fiber? The objective of the present study was to assess the nutritional characteristics and fiber contents of fresh fruits with low energy density. The study fruits wereabiu, bacuri, carambola, ingá-cipó, mapati, and taperebá acquired from the National Institute for Amazonian Research (INPA) and collected along kilometers 08 and 60 of highway BR174, AM-Brasil. Ash, protein, lipid, carbohydrate, energy and fiber contents were determined three times. The six fruits have very small and significantly different protein contents (p < 0.05). Taperebá and mapati presented the highest (4.65 g) and lowest (0.84 g) fiber contents, respectively. Except for abiu (0.49 g), the low lipid contents of the study fruits confirmed their low energy density. The soluble fiber content of the fruits was generally low, being highest in taperebá (1.51 g). The insoluble fiber fraction prevailed in all six study fruits, with taperebá and mapati presenting the highest (3.14 g) and lowest (0.65 g) insoluble fiber contents, respectively. The dietary fiber contents show that the study fruits can contribute to the composition of diets with appropriate dietary fiber contents and low energy densities.

Abstract: The objective of this study is to formulate and assess technologies for producing yogurt with camu-camu pulp, which has market potential and can be included in school meals, providing the general population with a nutritious and functional product. Three formulations of yogurt with camu-camu pulp were prepared, F1 10%, F2 13%, and F3 15%, with the following ingredients: whole UHT (Ultra High Temperature) milk, camu-camu pulp, dairy culture, and sugar. The micro-biological characteristics of the final products were within the standards recommended by ANVISA. Regarding sensory assessment, formulation 1 achieved the highest acceptability. The chemical, physical, and microbiological parameters were within the limits established by the legislation, and the acceptability of the formulation containing 10% camu-camu pulp was satisfactory. This is a more quality food option for the Amazonian and Brazilian population.

Abstract: Camu-camu (Myrciaria dubia (H.B.K.) Mc Vaugh) is a fruit native to the Amazon region and is considered the greatest natural source of vitamin C worldwide. It is also a promising source of many phenolic compounds, including flavonoids and anthocyanins. Given the growing rates of chronic non-communicable diseases such as dyslipidemia, obesity and diabetesworldwide, freeze-dried camu-camu can be used for its functional properties, which can reduce the incidence of these diseases. Hence, the objective of this study was to produce freeze-dried camu-camu pulp and present it as an alternative functional food because of its high production and use potential, adding value to this fruit in particular, not very demanded by the food industry. Freeze-dried camu-camu pulp is a pink, homogeneous powder with great antioxidant capacity, 52,000 μmol TE/g, six times greater than freeze-dried acai powder. It is also very rich in vitamin C (20.31 g/100g), potassium (796.99 mg/100g), carbohydrates (47.00 g/100g), dietary fiber (19.23 g/100 g), many amino acids, other vitamins, and anthocyanins (0.739 mg/g). The camu-camu freeze-drying process is an effective alternative way to preserve the fruit, preserving its macronutrient and vitamin C contents. Camu-camu is also an excellent source of other bioactive compounds, such as minerals and other phenolic compounds. In conclusion, camu-camu can be used to introduce bioactive compounds into food products and to delay or prevent many human diseases.
ética bibliotecária no contexto atual
Souza, Francisco das Chagas de;
Perspectivas em Ciência da Informa??o , 2007, DOI: 10.1590/S1413-99362007000100011
Abstract: the article discusses the thematics of ethics, taking the three last decades of the 20th century as reference. it considers that the current discussion indicates a predominance of the understanding of ethics under a simply practical perspective and quality gauging. there is also an indication that the mere invocation of ethics would be a sign strong enough to reach the desired solution of a problem of intersubjective nature. the paper presents the understanding that the simple use of the term ′ethics′ in the professional areas, such as library science, is not enough to solve the ethical issues; therefore its excessive invocation ends up contributing to halt a more realistic understanding of the facts almost entirely dehumanizing the ontological sense of life.
