No full textEste artículo se propone sintetizar las principales ideas de las ponencias presentadas en la Mesa de Trabajo "Los problemas de las Gimnasias" que se desarrolló en el marco del 9° Congreso Argentino y 4° Latinoamericano de Educación Física y Ciencias realizado en la Universidad Nacional de La Plata en junio de 2011. Todas ellas coinciden en pensar a la Gimnasia como parte fundamental de una Educación Corporal que se proponga transmitir aquellos saberes corporales culturalmente significativos que sirvan de herramientas para el conocimiento, el cuidado y la autogestión del propio cuerpo. A partir de estos puntos de coincidencia cada ponencia se explaya en su especificidad: ya sea desde la investigación y el análisis de los textos de divulgación y académicos, de los discursos de profesores, alumnos y practicantes; desde el análisis crítico del campo gímnico actual; desde propuestas bien concretas de trabajo de las gimnasias, en este caso la gimnasia aeróbica, la gimnasia funcional, el Método Pilates, o la gimnasia en el Profesorado en Educación Física con proyección en la gimnasia escolarThis article aims to synthesize the main ideas of the papers presented at the Workshop "The problems of Gymnastics", which was developed in the framework of 9th Argentine and 4th Latin American Congress of Physical Education and Sciences held in the National University of La Plata in June 2011. All of them agree in thinking of Gymnastics as a fundamental part of a Body Education that aims at transmitting culturally significant knowledge of the body which help as tool for knowledge, care and self-management of the body. From these points of agreement, each author develops its specific gymnastics topic: either from research and analysis of public outreach and academic texts, the discourse of teachers, students and trainees, or the critical analysis of current gymnastics field; also from concrete proposals of work in gymnastics, in this case, aerobics, functional gymnastics, Pilates Method or gymnastics in a Physical Education career projected towards school gymnasticsFil: Bulus Rossini, Viviana.

Synthesis and Characterization of Hydroxyapatite Powders From Eggshell For Functional Biomedical Application
No full textBulus, Erdi (Arel Author), İsmik, Deniz (Arel Author), Mansuroğlu, Demet Sezgin (Arel Author), Şahin, Yeşim Müge (Arel Author)Apatitic phosphates are considered within the category of bioceramics. HA and its derives are used of in the fields of medicine, orthopedics and dentistry in order to support a grow up of new bone cells. HA structures have a high biocompability and are widely in biomedical applications. On the other hand, synthesis of HA structures necessitates complex technologies (microwave sintering, hydrothermal synthesis etc.) and their production costs high. This study aims the production of nano apatitic structures with great biocompability from a natural material. Simple hotplate method was used to obtain natural, nano scale HA from eggshells. After calcination and sintering processes at different temperatures, the obtained apatitic phosphate powders have been structurally characterized by infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). Morphological investigation has been conducted by FEG-SEM images. Biological investigations have been carried out for the produced nanosized bioceramics and the results reveal that these nanomaterials are promising for tissue engineering purposes
Specialoperation som begrepp : Skiljer sig definitionen beroende på vilket lands operationer som studerats?
No full textSince the 1980s there has been an increase in the use of special operations and special forces. Although some theorists would say that the use of special operation is as old as the art of war, the scientific study in this subject is not extensive. The author of this dissertation have identified that the concept special operations is defined in different ways and that there seems to be a discrepancy in how the concept is understood among theorists. Harry Yarger, who has written a theory of American special operations states that there is a difference in how other countries conduct special operations. If that is true, definitions of special operations should vary according to nation. The first purpose of this study is to examine chosen definitions of special operations and to identify what differs and what is similar. The second purpose is to see if there is a connection between how the concept is defined and a which category it belongs to. The studied definitions are here categorized according to studies of cases and/or doctrines from one specified nation or several nations. At least two different definitions were chosen in each category, that way the author could compare the definitions within a category to see if they are consistent with each other. By identifying differences and similarities the authors intent was also to find what traits links the three different categories in order to be able to develop a more uniform definition of the concept special operation. The analysis has shown that there are many differences between categories as well as within categories and therefore the conclusion is indecisive – the author has not been able to establish if or not the there is a connection between how the concept is defined and a category. However, those similarities found in every category has been used to make a suggestion to a more uniform definition of special operations: Special operations are of an unorthodox nature. The purpose of these operations are to solve significant political and military problems. Missions can include time limited attacks aiming to destroy, seize, recover or exploit chosen objects. Special operations are conducted by special forces.

Antidiabetic phytodrug from Maerua angolensis DC: Formulation, standardization, in vitro and in vivo evaluations
No full textMaerua angolensis is a shrub or small tree widely distributed in tropical Africa. The plant materials are used for various ethnomedicinal applications across the region, including the prevention and treatment of diabetes. This study was aimed to evaluate the antidiabetic potential of formulated freeze-dried aqueous extract of Maerua angolensis leaves using standard in vitro and in vivo experimental models. Infusion extract of the plant's powdered dried leaves was prepared, the resultant extract was freeze-dried and formulated (denoted FIEMa). The physicochemical, quantitative and qualitative phytochemical constituents of FIEMa were determined using analytical techniques (UV-visible and HPLC). The antidiabetic activity of the reconstituted formulation was investigated using in vitro and in vivo models. The in vitro activity was assessed using Phosphomolybdenum assay and DPPH (2,2-Diphenyl-1-picrylhydrazyl) radical scavenging activity for antioxidant effect, and α-amylase inhibition and α- glycosidase inhibition assays. The assays of the normoglycemic, oral glucose load tolerance, and single-dose alloxan (150 mg/kg) induced diabetes in rats were used for in vivo antidiabetic activity. The results show that FIEMa contains valuable phytochemicals. It exhibited antioxidant effect, α-amylase and α- glucosidase inhibition activities. FIEMa did not significantly reduce blood glucose levels (BGL) in normoglycemic mice but produced a significant reduction of BGL in the oral glucose tolerance test. In alloxan-induced diabetic rats, significant reductions of BGL were observed in groups treated with high doses of FIEMa in the single-dose study and from the second week onwards in the repeated dose study. It also exhibited less reduction in body weight compared to the control group. The findings indicate that FIEMa has an antidiabetic activity, low risk of hypoglycemia, and body weight loss. The valuable phytochemicals plausibly mediate this effect, especially the dominant betulinic acid detected in FIEMa, most likely acting in synergy

No full textSimulation of metabolism-based herb-drug interaction: towards safe and efficacious use of NIPRD-AM1
No full textObjective: To evaluate the effect of NIPRD-AM1 on CYP3A4 in order to generate clinically significant data for its safe and efficacious use. Materials and Methods: NIPRD-AM1 is a phytomedicine developed from aqueous root extracts of Nauclea latifolia Smith (Rubiaceae) for the treatment of uncomplicated malaria. The effect of NIPRD-AM1 on CYP3A4 was measured with and without the addition of NIPRD-AM1, by testing different concentrations of the product at 37 °C in reactive mixtures with ketoconazole (2.5 µM) as the positive control. Results: Results showed a very low IC50 value of 0.01 mg/ml similar to that of ketoconazole (0.016 mg/ml). Conclusion: Metabolic processes of NIPRD-AM1 are likely to inhibit CYP3A4, with potential implication on drugs that are CYP3A4 substrates. This is a promising approach for guidance towards the safe and efficacious use of NIPRD-AM1
