Moderate Exercise Reduces Food Consumption in Obese Mice for Activate Jak-2/Stat-3 Pathway in the Hypothalami

It is very known that due to inflammatory processes the obesity leads to resistance to leptin, it reduces phosphorylation via JAK-2/STAT-3, which generates lower STAT-3 activity in the cell nucleus, and it leads to decrease the number of transcription of anorexigenic neurons (POMC/CART) and allowing transcription of orexigenic (NPY/AgRP). PURPOSE: The present study aimed to evaluate the effects of moderate aerobic training on food intake of obese mice through analysis of activity of hypothalamic proteins JAK-2/STAT-3. METHODS: It were used 30 Swiss mice (30 days old) divided into 3 groups: Control Group (C): sedentary animals fed with balanced diet ; Obese (OB) sedentary animals fed with high-fat diet throughout the experiment and Trained Obese (TOB) : animals fed with high fat diet throughout the experiment , kept sedentary during the first half of the experiment (8 weeks) and submitted to physical training protocol during the second half of the experiment (8 weeks). The exercise program consisted of treadmill running 1h, 5 days/week during 8 weeks at a speed equivalent to 60 % of maximum potency determined at the beginning of training period. To assess the leptin resistance, after rats were deprived of food for 6h with free access to water, they received i.p injection with leptin (2.0µl, 10-6M), after this, the chow was returned and food intake was determined by measuring the quantity and Kcal consumed at the end of 2h. The hypothalami was removed for determination of JAK-2 and STAt-3 activity. RESULTS: Our results showed that moderate physical exercise was effective in improving the JAK/STAT signaling pathway in the hypothalamus of obese animals. This has made these obese animals had reduced food intake and consequently lower body mass gain. CONCLUSION: It can be concluded that physical exercise, for restoring leptin signaling in the hypothalamus, controls the synthesis of neurons responsible for appetite and thus is an important tool in the treatment of obesity.

O que acontece durante o recreio em duas escolas da cidade de Jaú com crianças do 2º e 3º ano do ensino fundamental

This work had how I aim to notice what it happens in the recreation of two schools of basic teaching I, more precisely with children of the 2nd and 3rd year, analysing what they do and since they play. The interest in observing this moment is the fact of, at present, the children they have not many places to play, principally due to the violence and gradually places with structure for the same thing; the streets are already not any more places where the child can play the friends calmly, interact with other, his turn discovers the world and principally to enjoy itself. With these facts the school becomes the most appropriate place so that the child can play and interact with other children and at the same time to be protected leaving so the most carefree parents. The school becomes the great back yard in the life of the child, when several activities are happening there more and in this way developing not only the communication, the spirit of collaboration and of companionship, the co-ordination motora in general and the autonomy. Therefore the recreation makes an important time into the school life, moment in which the child can practise the universal right that is secured of playing

A Solid Film Electrode of Intermetallic Ag 2 Hg 3.02 for the Direct Determination of Folic Acid in Fresh and Processed Fruit Juices

AgSIE was used for the direct analysis of folic acid (FA), with a detection limit and lower level of quantitation of 6.8 x10-10 mol L-1 and 2.3 x 10 8 mol L-1. The analysis in fresh and processed fruits was done without any sample pretreatment. In strawberry and acerola juices, FA concentration level values were below the method detection limit. FA was detectable in peach (77.7 0.4 mg L-1 and 64.4 0.5 mgL-1), Persian lime (45.4 0.7 mg L-1), pineapple Hawaii (66.2 0.4 mgL-1), pear pineapple (35.3 0.6 mgL-1), cashew (54.4 0.5 mgL-1) , passion fruit (73.2 0.3 mgL-1), and apple (84.4 0.5 mg L-1 ).

Anelastic behavior due to interstitial oxygen in SmBa(2)Cu(3)O7-delta

The composite SmBa2Cu3O7-delta (Sm-123), obtained by the substitution of the ion Y for Sm in the very well known and studied YBa2Cu3O7-delta (Y-123), is potentially attractive for better understanding superconductivity mechanisms and for its applications as electronic devices. Sm-123 samples show higher critical temperatures than Y-123 ones do and a larger solubility of Sm in Ba-Cu-O solvent, which makes their growth process faster. When oxygen is present interstitially, it strongly affects the physical properties of the material. The dynamics of oxygen can be investigated by anelastic spectroscopy measurements, a powerful technique for the precise determination of the oscillation frequency and the internal friction when atomic jumps are possible. Anelastic spectroscopy allows determining the elasticity modulus (related to the oscillation frequency) and the elastic energy loss (related to the internal friction) as a function of the temperature. The sample was also investigated by X-ray diffraction (XRD), scanning electronic microscopy (SEM), and electric resistivity. The results obtained show a thermally activated relaxation structure composed by at least 3 relaxation processes. These processes may be attributed to the jumps of oxygen atoms present of the Cu-O plane in the orthorhombic phase.

Evidence for Millennial-Scale Climate Change During Marine Isotope Stages 2 and 3 at Little Lake, Western Oregon, U.S.A.

Pollen and geochemical data from Little Lake, western Oregon, suggest several patterns of millennial-scale environmental change during marine isotope stage (MIS) 2 (14,100–27,600 cal yr B.P.) and the latter part of MIS 3 (27,600–42,500 cal yr B.P.). During MIS 3, a series of transitions between warm- and cold-adapted taxa indicate that temperatures oscillated by ca. 2±–4±C every 1000–3000 yr. Highs and lows in summer insolation during MIS 3 are generally associated with the warmest and coldest intervals. Warm periods at Little Lake correlate with warm sea-surface temperatures in the Santa Barbara Basin. Changes in the strength of the subtropical high and the jet stream may account for synchronous changes at the two sites. During MIS 2, shifts between mesic and xeric subalpine forests suggest changes in precipitation every 1000–3000 yr. Increases in Tsuga heterophylla pollen at 25,000 and 22,000 cal yr B.P. imply brief warmings. Minimum summer insolation and maximum global ice-volumes during MIS 2 correspond to cold and dry conditions. Fluctuations in precipitation at Little Lake do not correlate with changes in the Santa Barbara Basin and may be explained by variations in the strength of the glacial anticyclone and the position of the jet stream.

Local structure around Fe ions on multiferroic Pb(Fe1/2Nb1/2)O-3 ceramics probed by x-ray absorption spectroscopy

Local structure around Fe ions on Pb(Fe1/2Nb1/2)O-3 ceramics was probed by x-ray absorption spectroscopy in order to settle the controversies about its structure. It is observed that the shell structure around Fe atoms exhibits a monoclinic local symmetry at 130 and 230 K, tetragonal local symmetry at room temperature, and cubic local symmetry at 410 K. Independently of the coordination, temperature, or symmetry, Fe-O mean bond-length does not vary significantly. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4709490]
