Cristina Velasquillo, Eduardo A. Galue, Lourdes Rodriquez, Clemente Ibarra, L. Guillermo Ibarra-Ibarra
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2013, DOI: 10.4236/jcdsa.2013.31A012
Abstract: Tissue engineering has been used for the treatment of several skin diseases and lesions; however, tissue engineering and regenerative medicine also have a huge potential in cosmetology. They include skin substitutes, cell therapy and wound-healing treatments based on biomaterial-based replacements and 3D systems. This review focuses on the bioprinting technology and how it can improve skin functions, restoring pigmentation or helping hair follicles to develop.

Abstract: spinal cord injury (sci) is a trauma problem striking mainly working age adults, therefore affecting society beyond the victim?s family circle. most of the victims of sci will never recover; therapy for this type of injury consists basically on spinal cord support and stabilization. with the discovery of stem cells (sc), sci treatment has been given another chance. stem cells are responsible for tissue renewal throughout the individual?s life, as well as tissue repair when needed. from the therapeutic point of view, the most appealing sc are those capable of generating a variety of tissues, those easily harvested, and finally, those ethically unquestioned. this article summarizes some studies carried with sc of various origins and their application to sci treatment.

C. Mendoza-Barrera,L. A. Bahena-Navarro,M. A. Meléndez-Lira,C. Velasquillo
Revista mexicana de física , 2006,
Abstract: La electrodeposición química es una técnica de crecimiento barata que presenta diversas ventajas entre ellas podemos mencionar: amplia disponibilidad de precursores que permiten controlar el pH y concentración del electrolito fácilmente, el control de espesores en las películas, uniformidad, razón de depósito y procesos isotérmicos, entre otros. En el presente trabajo reportamos el dise o, construcción y aplicación de un sistema de electrodepósito químico. El desempe o del sistema es probado depositando el biopolímero quitosan, el segundo biopolímero más abundante en la naturaleza, sobre acero inoxidable 316L. Las películas obtenidas fueron caracterizadas con técnicas que son empleadas comúnmente en el estudio de materiales no biológicos. Las características vibracionales, estructurales y químicas fueron obtenidas mediante espectroscopía infrarroja (IRS), microscopía electrónica de barrido (SEM) y espectroscopia de energía dispersiva de rayos X (EDS) Las películas de quitosan fueron depositadas sobre el electrodo negativo, encontrándose que su morfología depende del pH y concentración de la solución.
Family, Poverty and Inequalities in Latin America and the Caribbean  [PDF]
Cristina Gomes
Sociology Mind (SM) , 2013, DOI: 10.4236/sm.2013.31005

This article adopts the concept of development as freedom and the relationship between income and capabilities to analyze and compare macroeconomic, demographic and poverty trends and inequalities in Latin American and the Caribbean countries, and the responses from governments to promote the inclusion of the poorest and marginalized population groups in development and policies. Differences in population structures indicate that poverty and gender, generational and race inequalities fragment societies. Policies oriented to reduce poverty have been implemented with a set of combined programs such as cash transfers articulated with actions in nutrition, health, education, day-care programs for poor children, civil registration and other programs to promote poverty reduction and the conciliation of domestic and work life for poor women and social protection. Some good practices are discussed, particularly in Brazil and Mexico. During the last 15 years, the Conditioned Cash Transfers programs raised public support and political consensus, guaranteeing continuity in their implementation, development and integration with other social protection programs. Currently there are 18 countries implementing such programs, covering approximately 25 million households and over 133 million people, representing 19% of the Latin American and Caribbean. Policies to reduce poverty, in combination with income distribution and social protection in nutrition, health, education, civil registration and day-care for children, have contributed to human development, and also promoted internal market of consumers, even in rural areas, mobilizing local economies and promoting the return of investments to development. Despite the economic crisis in 2008-2009, Latin America had a relatively good performance in the world economy, demonstrating that social and economic

Family and women decide child nutrition—The role of human development, capabilities and lifestyles  [PDF]
Cristina Gomes
Health (Health) , 2013, DOI: 10.4236/health.2013.57153

In this article, capacities and freedom approach, as well as lifestyles are explored taking into account child nutrition, and other relevant dimensions of human life more than just economic and other elementary resources, and also social, cultural, psychological, values and freedom dimensions. Nourishment, health and survival are considered some of the elementary capabilities, and the concept of malnutrition, including under and over-nutrition, is discussed, based upon the comparison of data on food production and distribution from the macro level context, as well as from the family and individual levels included anthropometrical measurements. The advantages and limits of different kinds of measurements are discussed, suggesting more complex approaches, based also upon family and gender equality. The double burden of malnutrition, under and over-nourishment of children is highlighted as a public health issue to be resolved by adequate policies and considering the role of female empowerment, nutrition-knowledge and education as relevant keys to achieve equality in family food and resource distribution, healthy lifestyles and human development.

Education, Work and Reproductive Health among Adolescents in Latin America and the Caribbean  [PDF]
Cristina Gomes
Advances in Applied Sociology (AASoci) , 2013, DOI: 10.4236/aasoci.2013.32019

Investments in education, work, and the sexual and reproductive health of adolescents and youth contribute to their human development and autonomy, and guarantee that they will have their own resources and pensions for old age. In Latin America and the Caribbean 100 million adolescents aged 10 to 19 years demand schools and teachers in secondary education, employment and health services. This work describes and analyses the situation of adolescents and youths in these three areas of interest, as a basis for defining priorities and the integration of policies oriented to take advantage of the demographic bonus and to enhance the sustainability of future dignified ageing for youth generations. Since Latin America and the Caribbean is the region with the highest inequality rates in the world, investing in demographic dividend can also contribute to decreasing inequalities in the long term. Secondary data from censuses, surveys and international organizations are analysed to relate to the three relevant issues of interest. Most than half of teens in Central America, and between 20% and 40% of adolescents in South America leave school before completing secondary level education and most of them receive poor quality education, 20% of them do not study or work and some are trapped in a triad of problems: the secondary school dropout, unemployment, informal and unprotected work and adolescent pregnancy. Despite the decline in adolescent fertility rates, they continue to be up to seven times higher among the less educated. Unemployment rates are three times higher for young people than for adults, half of them work in informal and low skilled jobs. The relationship between health, education, employment, poverty and inequalities demonstrates the need to strengthen and integrate policies of inclusion at school and at work, as well as special protection and social security for adolescents and youth.

From Prototype and Skopos Theories to Corpus-Based and Audiovisual Approaches in Children’s Literature Translation  [PDF]
Cristina Chifane
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.38011
Abstract: For a long time an unexploited field of scientific research, Children’s Literature Translation Studies deserve a thorough examination primarily due to the current world-wide publishing boom of children’s texts. The dominance of the literary productions of the Anglo-American environment determines the overwhelming number of translations in different cultures and languages. Most translation theories which have been traditionally analyzed and applied to what is generally assumed to be adult literature should be revisited and reconsidered in the case of children’s books with the aim of helping translators and ensuring the efficiency of the translation process. From this perspective, the present article focuses upon the influence of the prototype theory upon children’s literature translation strategies, the importance of the double addressee in the skopos theory, the advantages of the corpus-based approach and the adaptation to the changing landscapes of children’s texts intermediated by the audiovisual approach. Since contemporary translators of children’s literary texts are facing the imperative of tight deadlines, they need to be clearly aware of their translation commission trying to fulfill the expectations of the potential target readers. The aforementioned theories and approaches pave the way to new discoveries with respect to the challenge of translating children’s texts which share both similarities and differences with adult literature.
Racism in Health Services in Brazil  [PDF]
Cristina Gomes
Advances in Applied Sociology (AASoci) , 2016, DOI: 10.4236/aasoci.2016.611027
Abstract: This article discusses racial prejudices and discrimination in perceptions, attitudes and practices among health personnel in the municipality of Camaçari. The survey’s methodology included racist statements in questionnaires distributed to 634 health workers, as well as socio-determinants of health, family and work characteristics. Results indicate how masked racism is reproduced through ambiguous attitudes and practices; the feeling that speaking about race/color would create a racist conflict, supposing that it does not exist, and resistance against accepting the need to correct injustices and promoting affirmative policies.
Elites in Competition and the Reorganization of Power: The Case of Brazil  [PDF]
Cristina Gomes
Sociology Mind (SM) , 2019, DOI: 10.4236/sm.2019.91002
Abstract: This article describes the formation of the traditional elite of Brazil from the colonial period, and the main ruptures affecting the republic during short democratic periods in which changes were observed in the composition of their elite. The most recent change is historically contextualized by the formation of a new elite, in the form of the governments of Lula da Silva and Dilma Rousseff, who were never part of the political-military-hereditary lineage of traditional elites. This was the scenario of the 2014 elections and the impeachment that once again broke away from the democratic system. The historical practices of the traditional elite of Brazil showed themselves to be caught in a vicious circle around the coup d’état to return to power, confronting the responses of the new progressive elite that had resulted from elections during the short periods of democracy. A qualitative methodology of bibliographic review is applied for the construction of the conceptual and analytical framework, and the collection of information from the media for recent facts has still been little analyzed with content analysis, and is complemented with two interviews with people who occupied high government posts, both before and during the coup. The results indicate that the new government elite undervalued the process of financial globalization and promoted the strengthening of representatives of international networks and their entry into the decision-making process, where they formed parallel command structures and networks contrary to government decisions and facilitated the rupture of democracy.

Proteome Science , 2010, DOI: 10.1186/1477-5956-8-27
Abstract: In this study, 147 proteins were visualized, and 47 proteins were identified by MS. A significant proportion of proteins are involved in metabolic processes and energy (32%), as well as participating in different biological functions including structural organization (19%), signal transduction and molecular signaling (11%), redox homeostasis (9%), transcription and protein synthesis (6%), and transport (6%). The identified proteins were assigned to one or more subcellular compartments.Among the identified proteins, we found some proteins already recognized in other studies such as OA-associated proteins. Interestingly, we identified LXN, an inhibitor of mammalian carboxypeptidases, which had not been described in articular cartilage. Immunolabeling assays for LXN showed a granular distribution pattern in the cytoplasm of most chondrocytes of the middle, deep and calcified zones of normal articular cartilage as well as in subchondral bone. In osteoarthritic cartilage, LXN was observed in superficial and deep zones.This study provides the first proteomic analysis of normal articular cartilage of rat. We identified LXN, whose location was demonstrated by immunolabeling in the chondrocytes from the middle, deep and calcified zones of normal articular cartilage, and superficial and deep zones of osteoarthritic cartilage.Articular cartilage is a specialized connective tissue and its principal functions are reduction of friction in the joint, resistance to compressive forces and distribution of load [1]. Macromolecules that constitute the extracellular matrix (ECM) of cartilage such as collagens and proteoglycans (PGs) make the reproducibility of protein profiles difficult, interfering with isoelectric focusing (IEF) and masking minor cell proteins [2]. Previous studies reported the use of different selective extraction techniques in human and animal cartilage models, which allowed the rapid and efficient detection of protein expression patterns [3-5].Proteomic technology
