Background: Obesity has reached epidemic patterns and constitutes a serious public health problem due to comorbidities and the impact on life quality of affected individuals. Bariatric surgery appears as one of the most recommended treatments;however much has been known about the effects of this intervention on the functional performance of the organism as a whole. Objective: To characterize the oral health of adults submitted to bariatric surgery, before and after the intervention, with emphasis on the performance of masticatory function. Methods: A prospective observational cohort study conducted in a public reference service to the treatment of obesity in the city of Recife, State of Pernambuco. The data were obtained during the first half of 2011, through interview, intraoral physical examination and evaluation of masticatory function. Statistical treatment adopted was a CI of 95% and the chi-square test. The collection was conducted in three stages, with initial assessment in the preoperative and follow-up at 60 and 180 days. Results: The sample consisted of 20 volunteers, aged between 23 and 58 years and mean BMI of 43.2 ± 2.8. When compared the pre-operative to the control periods, there were significant differences for variables with decreased tendency towards spontaneous gingival bleeding and increased tooth hypersensitivity and tooth mobility (p < 0.05). Regarding the masticatory function, we found significant differences for most of the variables investigated, except in the coordination of movements and breathing during this function. Conclusion: The performance of masticatory function shows differences in pre- and postoperative periods for bariatric surgery.

Fungal endophytic species inhabiting the leaves of eucalypts are capable of utilising leaf sugars and can influence both plant growth and health. Endophytic fungal symbionts can use simple soluble sugars in leaves as their main carbon source. This study set out to determine the diversity and distribution of the endophytic filamentous fungal leaf community in the hybrid Eucalyptus urograndis due to its economic importance. The fungal leaf community was characterised using denaturing gradient electrophoresis (DGGE) and correlated with levels of leaf nutrients and sugars throughout plant development. Sequencing of DGGE bands revealed the presence of Basidiomycota and Ascomycota phyla. Fourteen species and three genera of filamentous fungi were identified, and the population structure was affected by the plant developmental stage. Levels of K, Cu, N and Mn influenced communities from the clonal garden, whereas leaves in the field had higher glucose, fructose and sucrose. Many fungi were found to be specific to a certain development stages: Diplomitoporus crustulinus, Podosphaera tridactyla and Aspergillus restrictus to the clonal garden stage;Chaetomella acutiseta and Ascotricha chartarum to the shading stage;Erratomyces patelii and Saxomyces sp. to the shading output stage;Lepidostroma sp. and Saxomyces sp. to the dispatch stage;and Mycosphaerella populicola to the field stage. Teratosphaeria toledana and Teratosphaeria acidotherma were found at more than one developmental stage. Cladosporium sp. and Rhodosporidium fluviale colonized and persisted in plants at the dispatch and field stages. This is the first report of P. tridactyla, A. restrictus, E. patelii, Saxomyces and Lepidostroma sp. as endophytes in eucalipt.

The Role of Fructose in Public Health and Obesity

We are in the so-called nutritional transition, in which obesity and its comorbidities have emerged as an important research topic, and the information on food composition is fundamental to promote nutritional safety. Fructose is the sweetest carbohydrate, and this sweetness, along with its low cost, is the key factor for its use in commercial drinks and sweets. The global average consumption of fructose per capita has increased from 56 g/day in 1986 to 65 g/day in 2007. Experimental models associate high fructose intake with the development of obesity and induced insulin resistance. In recent studies, diabetic patients have been reported to use fructose more frequently than glucose. Fructose acts differently in the hypothalamus and generates less satiety than glucose;thus, fructose has a high lipogenic potential. Replacing fructose with another isocaloric carbohydrate is associated with better glycemic control.

In this paper we report for the first time the presence of bistability in an acoustic-optic tunable filter (AOTF) operating with ultrashort (2 ps) optical light pulses. The results for the study of bistability has shown the dependence of the hysteresis curve with the product of the coupling constant (κ) by the length of the device (ξL) and the conversion power-coupling constant factor (G). The range of bistability varies significantly with both G and with κξL parameters. The variation of κξL directly increases the size of the range of bistability hysteresis while the increase in G causes the bistability to occur at low powers. The phenomenon of optical bistability (OB) is the object of increasing interest due to its possibilities for important device applications. A bistable device is a device with a capability to generate two different outputs for a given input and the physical requirements for this are an intensity-dependence refractive index and an optical feedback mechanism.
