Abstract: Localized lipodystrophy represents a regional accumulation of adipose tissue whose cells count on α1, α2and β adrenergic receptors which control lipolytic processes. Therapeutic ultrasonography has been shown as an efficient auxiliary resource in the reduction of measures, as well as in the elimination of localized fat onceits action can be effectively potentialized by phonoforesis. Ultrasonography mechanical and/or thermal effectpromotes modifications on the intercellular linkage and an increase in the cellular membrane permeability,what leads to a better diffusion of substances through the skin. Metilxantines (such as caffeine andaminofilin), besides being α1 blockers, also block phosphodiesterase, while ioimbin blocks α2, whatcontributes for the activation of adenylatecyclase and for lipolysis. The present study aimed to assess theeffects of 3MHz ultrasound associated to the use of lipolytic actives in the reduction of localized fat in theinfra-abdominal region. In a double-blind, longitudinal, randomized, and experimental clinic study, 27sedentary women with ages ranging from 18 to 30 y-o (without hormonal disturbs, and in current use ofcontraceptive medication) were enrolled. All voluntaries underwent a total of 12 sessions (3 times a week) ofphonoforesis with 2% caffeine, aminofilin and ioimbin each. The sample was divided in three groups: GroupUS – 3MHz continuous ultrasound with gel and without lipolytic actives; Group US+Actives – 3MHzcontinuous ultrasound with gel containing lipolytic actives; and Group CTRL – unplugged 3MHz ultrasound(control group). The variables assessed were adipometry, perimetry, and pre- (1st session) and post- (12thsession) treatment ultrasound. Our findings exhibit post-treatment reductions both in infra-abdominaladipometry and perimetry for all groups when compared to pre-treatment values (p<0.05). No post-treatmentultrasonography scores were found to be different from pre-treatment values (p>0.05). Group US+Activesshowed differences in adipometry when compared to Group CTRL (p<0.05). Group US showed differencesin adipometry, perimetry and ultrasonography when compared to Group CTRL (p<0.05). According to thisstudy, It may be concluded that therapeutic 3MHz ultrasound associated to lipolytic actives is as effective inthe reduction of infra-abdominal adiposity as therapeutic ultrasonography alone was also significantlyfavorable. Control group subjects loss of weight may be due to uncontrolled changes in diet.

Abstract: pilots from brazilian air force academy (afa) perform strentgth- and accuracy-demanding hand movements, which may modify muscle strength. the aim of this study was to analyse hand isometric strength of grip and pulp-to-pulp, tripode and lateral pinch in three groups of male afa pilots: ads (air demonstration squadron), n=15; ip (instructor pilots), n=16; and tp (training pilots), n=6. pilots body positioning during tests followed the standards of the american society of hand therapists; the sequence of assessed movements was predefined in order to prevent muscle fatigue. the maximum isometric muscle force was collected in a contraction kept for 6 seconds. as to grip, results show significant differences within all groups, favouring dominant hands; also, mean ads grip values were significantly higher than the other groups'. tripode pinch ads mean values were significantly higher than training pilots'; and dominant hands significantly overtopped non- dominant ones in ads and ip groups. it may thus be said that specific hand muscle training during flight, as well as training specialization and duration influence hand isometric muscle strength.

Abstract: Interspecies DNA transfer is a major biological process leading to the accumulation of mutations inherited by sexual reproduction among eukaryotes. Lateral DNA transfer events and their inheritance has been challenging to document. In this study we modified a thermal asymmetric interlaced PCR by using additional targeted primers, along with Southern blots, fluorescence techniques, and bioinformatics, to identify lateral DNA transfer events from parasite to host. Instances of naturally occurring human infections by Trypanosoma cruzi are documented, where mitochondrial minicircles integrated mainly into retrotransposable LINE-1 of various chromosomes. The founders of five families show minicircle integrations that were transferred vertically to their progeny. Microhomology end-joining of 6 to 22 AC-rich nucleotide repeats in the minicircles and host DNA mediates foreign DNA integration. Heterogeneous minicircle sequences were distributed randomly among families, with diversity increasing due to subsequent rearrangement of inserted fragments. Mosaic recombination and hitchhiking on retrotransposition events to different loci were more prevalent in germ line as compared to somatic cells. Potential new genes, pseudogenes, and knockouts were identified. A pathway of minicircle integration and maintenance in the host genome is suggested. Thus, infection by T. cruzi has the unexpected consequence of increasing human genetic diversity, and Chagas disease may be a fortuitous share of negative selection. This demonstration of contemporary transfer of eukaryotic DNA to the human genome and its subsequent inheritance by descendants introduces a significant change in the scientific concept of evolutionary biology and medicine.

Abstract: an epidemiological chain involving trypanosoma cruzi is discussed at the environmental level, and in terms of fine molecular interactions in invertebrate and vertebrate hosts dwelling in different ecosystems. this protozoan has a complex, genetically controlled plasticity, which confers adaptation to approximately 40 blood-sucking triatomine species and to over 1,000 mammalian species, fulfilling diverse metabolic requirements in its complex life-cycle. the tr. cruzi infections are deeply embedded in countless ecotypes, where they are difficult to defeat using the control methods that are currently available. many more field and laboratory studies are required to obtain data and information that may be used for the control and prevention of tr. cruzi infections and their various disease manifestations. emphasis should be placed on those sensitive interactions at cellular and environmental levels that could become selected targets for disease prevention. in the short term, new technologies for social mobilization should be used by people and organizations working for justice and equality through health information and promotion. a mass media directed program could deliver education, information and communication to protect the inhabitants at risk of contracting tr. cruzi infections.
