Pulsed ultrasound therapy accelerates the recovery of skeletal muscle damage induced by Bothrops jararacussu venom
Saturnino-Oliveira, J.;Tomaz, M.A.;Fonseca, T.F.;Gaban, G.A.;Monteiro-Machado, M.;Strauch, M.A.;Cons, B.L.;Calil-Elias, S.;Martinez, A.M.B.;Melo, P.A.;
Brazilian Journal of Medical and Biological Research , 2012, DOI: 10.1590/S0100-879X2012007500033
Abstract: we studied the effect of pulsed ultrasound therapy (ust) and antibothropic polyvalent antivenom (pav) on the regeneration of mouse extensor digitorum longus muscle following damage by bothrops jararacussu venom. animals (swiss male and female mice weighing 25.0 ± 5.0 g; 5 animals per group) received a perimuscular injection of venom (1 mg/kg) and treatment with ust was started 1 h later (1 min/day, 3 mhz, 0.3 w/cm2, pulsed mode). three and 28 days after injection, muscles were dissected and processed for light microscopy. the venom caused complete degeneration of muscle fibers. ust alone and combined with pav (1.0 ml/kg) partially protected these fibers, whereas muscles receiving no treatment showed disorganized fascicules and fibers with reduced diameter. treatment with ust and pav decreased the effects of the venom on creatine kinase content and motor activity (approximately 75 and 48%, respectively). sonication of the venom solution immediately before application decreased the in vivo and ex vivo myotoxic activities (approximately 60 and 50%, respectively). the present data show that ust counteracts some effects of b. jararacussu venom, causing structural and functional improvement of the regenerated muscle after venom injury.
Evasion of immune responses by Trypanosoma cruzi, the etiological agent of Chagas disease
DosReis, G.A.;
Brazilian Journal of Medical and Biological Research , 2011, DOI: 10.1590/S0100-879X2011007500005
Abstract: infection with the protozoan parasite trypanosoma cruzi leads to chagas disease, which affects millions of people in latin america. infection with t. cruzi cannot be eliminated by the immune system. a better understanding of immune evasion mechanisms is required in order to develop more effective vaccines. during the acute phase, parasites replicate extensively and release immunomodulatory molecules that delay parasite-specific responses mediated by t cells. this immune evasion allows the parasite to spread in the host. in the chronic phase, parasite evasion relies on its replication strategy of hijacking the tgf-β signaling pathway involved in inflammation and tissue regeneration. in this article, the mechanisms of immune evasion described for t. cruzi are reviewed.
Feeding Responses in Snailets of African Giant Land Snails (Archachatina marginata) to Different Food Items in the Sub-Saharrah Tropical Region, Nigeria
G.A. Lameed
Journal of Animal and Veterinary Advances , 2012,
Abstract: The study of feeding responses of snailets of African giant snail (Archachatina marginata) fed with different food items: Ugwu leave (Talfairia sp.), Pawpaw fruit (Carica papaya), banana fruits (Musa sapientum) and three levels of compounded feed with crude protein: 16.25, 15.88, 15.60% was carried out in the University Mission Research (UMR) snailery unit. Six treatments (T1-T6) were established with fifty snailets each and fed with different food items under the same environmental condition. Observations were made on feed utilization (intake), growth rates and mortality rates that were recorded bi weekly, which covered a period of six months. Results showed that the snailets in all the treatments utilized the feed types significantly (p<0.05); while the feed intake with respect to growth pattern (weight gain) in treatments 1-6 had no significant difference (p>0.05). Snailets fed with compounded feed (T: 6) with mean intake and mean growth rates: 12.57 and 2.96 g, respectively had the best performance. Highest mortality rate (46%) was recorded in treatment 3 fed with banana and the least rate was generally obtained from compounded feed in treatment 4 with 16% mortality. It can be concluded that snailets in treatment 6 (compounded feed) with higher crude protein percentage (15.60%) had the highest total weight gain and mean total feed intake of 1480 and 12.57 g, respectively, when compared with other treatments.

Comparison of Nodal Distribution of Soybean Cultivars' Yield Components in Different Planting Dates
G.A. Ranjbar
Pakistan Journal of Biological Sciences , 2007,
Abstract: Aim of this study was to determine planting date effects on Nodal distribution of yield and its components in nine indeterminate soybean cultivars. To meet such a purpose, a split plot design based on a randomized complete block layout with six planting dates (24th April, 10th and 27th May, 10th and 26th June and 11th July) as main plots and nine cultivars (Williams, Clark 63, SRF 450, Steele, Hark, Corsoy, Blackhawk, Woodworth and Bonus) as sub plots have been used in five replications. The results have clarified that height, branch number, pod number, grain number and seed weight plays an important role on yield increasing. So that, medium maturity cultivars have producing maximum number of pods, grains and seed weight in their upper two third of canopy. Also, various cultivars have indicated different reactions for yield components, so that, Williams and Woodworth (medium maturity cultivars), Steele and Bonus (early maturity cultivars) have produced larger seeds in different planting dates. Generally, Woodworth, in comparison with the other cultivars, demonstrating superiorities in all the considered traits. Maximum amount of pod number, grain number and seed weight in early maturity cultivars was belong to 27th of May planting date, however, for Woodworth and Clark 63 (medium maturity) it was 24th of April and 27th of May, respectively. The highest 100 seed weight per node were produced at 26th of June and 27th of May planting dates by Woodworth and Corsoy, respectively. Differences between planting dates for 100 seed weight in Clark 63 and Bonus were not significant.

Recent advances in M3 (mechanics on the material manifold)
Maugin G.A.
Theoretical and Applied Mechanics , 2002, DOI: 10.2298/tam0229221m
Abstract: After a brief critical review of the basic arguments involved in the various interpretations of the mechanics on the material manifold and a short remark on the relationship of that approach with the late R.Stojanovi 's works, some of the recent advances in that field of continuum physics are presented. These include direct consequences in the numerics of solid-mechanics problems, general applications to the theories of plasticity, growth and mixtures, and a nonstandard application to the progress of phase- transition fronts in solids. .
