A Technical Tip in Microlipofilling

Lipofilling has become a very important tool in plastic surgery today, since the first experience of autologous fat graft described more than one hundred years ago. Technical developments have led to a more delicate procedure called microlipofilling, in which thin cannulas or needles are used. A frequently discussed technical difficulty is how to inject with a small cannula the fat collected with a larger one. The authors describe their personal maneuver to resolve the above mentioned problem.

Anti-allergic activity of the Morinda citrifolia extract and its constituents

Possible Application of the Medicinal Plant Hyoscyamus albus in Phytoremediation: Excess Copper Compensates for Iron Deficiency, Depending on the Light Conditions

Seedlings of the medicinal plant Hyoscyamus albus were supplied with an excess of Cu to examine the possible application in phytoremediation. The seedlings were cultured in B5 medium supplied with basal 0.1 μM Cu and 200 μM Cu under various light conditions: short day (SD); long day (LD); and continuous light (CL). In addition, the effect of supplying 200 μM Cu under Fe deficiency was determined, in order to elucidate the interaction between Cu and Fe. Interestingly, Fe-deficiency symptoms that developed in plants grown with basic levels of Cu under LD almost disappeared when excess Cu was supplied. Plant growth mainly depended on the photo irradiation period (SD < LD~CL); and 200 μM Cu did not inhibit growth at all when Fe was available, whereas in the absence of Fe, CL caused damage to growth. Analysis of the Cu and Fe contents of the plants revealed that Cu was distributed equally in both the aerial parts and roots, whereas most of the Fe was found in the roots; under Fe deficiency, Cu accumulation in the roots apparently increased. Cu was mainly distributed in the soluble fraction, which included vacuoles and the cell-wall fraction. These results provide evidence indicating that H. albus seedlings are tolerant of Cu present in excess. Furthermore, excess Cu was able to compensate for Fe deficiency, depending on the light conditions. Continuous light inhibited this effect, probably as a result of the induction of Mn deficiency. The possible applications of this newly discovered cuprophyte are discussed

The “In-Between” Intercultural Knowledge Production: A Case Study from the Teacher Training Kaingang Ethnicity in Southern Brazil

As a reflection of an ongoing research project, whose wider scope of analysis focuses in the expectations and produced stares about indigenous education by students of Kaingang ethnicity enrolled in Graduation Bachelor Courses in Indigenous Intercultural Pedagogy, Mathematics and Sciences of Nature, all three offered by the Universidade Comunitaria da Regi?o de Chapeco (Unochapeco), this study problematizes to what extend the intercultural knowledge acquired over the training process of Kaingang indigenous teachers may be converted into reflections focused on their conceptions of education, (re) signification of their identity and autonomy within a context of an intense multiculturalism emergence as well as cultural hybridism, which characterize contemporaneity. The results indicate that, for those students, the intercultural knowledge may be triggering as an instrument of changes, inside and outside their communities; it strengthens and nourishes the debate around the role of formal education, the school and the indigenous teacher as a mediator between worldviews and cultures, in constant confluence.

Chocolate Milk with Sucrose and Stevia Preference by Pre- and Post-Menopausal Women

The objective of this study was to evaluate and compare the preference of chocolate milk products sweetened with sucrose and stevia by pre- and post-menopausal women and to examine their concerns about bone health. Women panelists were divided into two groups according to age: pre- menopausal (from 18 to 47 years old) and post-menopausal (over 48 years old) and answered the frequency of white and chocolate milk consumption during a week and their concerns about bone health. For preference, five kinds of chocolate milk were used: 1) Non Sucrose Added [NSA] with stevia and NutraFlora?, 2) NSA with stevia, 3) with sucrose and stevia, 4) with sucrose, stevia, and NutraFlora?, and 5) control with sucrose. The results showed that both groups (pre- and post- menopausal women) prefer chocolate milk to white milk. Pre-menopausal women prefer the chocolate milk with NSA stevia and NutraFlora?, while post-menopausal women prefer the chocolate milk NSA with stevia without NutraFlora?. For comparisons between chocolate milk with sucrose and stevia vs. chocolate milk with sucrose and stevia and NutraFlora? and chocolate milk with sucrose vs. chocolate milk with sucrose and stevia, there were no visible differences between pre- and post-menopausal women. Both groups were concerned about bone health, fiber, and calories, and their concerns about which influenced their milk choices. Pre-menopausal women showed a greater positive impact on milk choice when being informed the amount of fibers in the sample than post-menopausal women. Therefore, this study suggests that milk sweetened with stevia needs to be produced as calcium resources without increasing calories.

Identification and characterization of microRNAs expressed in chicken skeletal muscle

MicroRNAs (miRNAs, miRs) encompass a class of small non-coding RNAs that often negatively regulate gene expression. miRNAs play an essential role in skeletal muscle, determining the proper development and maintenance of this tissue. In comparison to other organs and tissues, the full set of muscle miRNAs and its expression patterns are still poorly understood. In this report, a chicken skeletal muscle miRNA library was constructed, and the expression of selected miRNAs was further characterized during muscle development in chicken lines with distinct muscling phenotypes. Clone library sequence analysis revealed 40 small RNAs with similarities to previously described chicken miRNAs, seven miRNAs that were never identified before in chicken, and some sequence clusters representing other possible novel miRNAs. Temporal expression profiles of three miRNAs associated with cell proliferation and differentiation (miR-125b, miR-221, and miR-206) in two chicken lines (broiler and layer) revealed the differential steady-state levels of these miRs during skeletal muscle growth and suggests that miR-206 is involved in the muscling phenotype that is observed in growth-selected chicken lines.

Fourier transform infrared photoacoustic spectroscopy as a potential tool in assessing the role of diet in cuticular chemical composition of Ectatomma brunneum

The cuticular chemical composition plays a significant role in the recognition of nest mates in social insects, thus functioning as a chemical signature of the colony. The structure of cuticular chemicals is subject to interference from genetic and exogenous factors, including diet. In this study, various colonies of the Ectatomma brunneum ant were removed from their natural environment and housed in a laboratory to monitor the response of the cuticular chemical composition to dietary changes. Analyses were performed using gas chromatography and Fourier transform infrared photoacoustic spectroscopy, which has not been previously used for this type of analysis. The results indicate that this method is useful for analyzing biological and natural systems. We observed changes in the chemical signature with food traces in the first 30 days under feed control. Therefore, genetic information may not be the only criterion that can be used to describe the chemical signature of a species; environmental variations also influence recognition signals. Furthermore, these results reinforce the reliability of the Fourier transform infrared photoacoustic spectroscopy method.
