Posibilidades abiertas por las nuevas tecnologías en el desarrollo de los cines africanos contemporáneos
Beatriz Leal Riesco
Caracteres : Estudios Culturales y Críticos de la Esfera Digital , 2012,
Abstract: From its beginnings with the wave of independence that swept the continent in the middle of the previous century, African cinema has remained subordinate to and dependent upon Western aid. Barring a few prominent exceptions, the effects of this phenomenon have been visible, with films made catering to the tastes of occidental critics and cinephiles while African viewers have been left thirsting for images and sounds of an autochthonous character. Since the 1990’s, thanks to new technologies, African cinema has achieved a previously inconceivable vitality and autonomy. The democratizing effects of the reduction in the cost of production, distribution, and exhibition, as well as the easier accessibility of new technologies to non-professionals, has made of Africa a creative flashpoint, where myriad voices work to create a nuanced and polyphonic imaginary leagues beyond those prejudices and stereotypes of occidental provenance that have overshadowed this continent’s cinematography for more than five decades.
Sialoglycoconjugates in Trypanosoma cruzi-host cell interaction: possible biological model - a review
Vermelho, Alane Beatriz;Meirelles, Maria Nazareth Leal;
Memórias do Instituto Oswaldo Cruz , 1994, DOI: 10.1590/S0074-02761994000100013
Abstract: a number of glycoconjugates, including glycolipids and glycoproteins, participate in the process of host-cell invasion by trypanosoma cruzi and one of the most important carbohydrates involved on this interaction is sialic acid. it is known that parasite trans-sialidase participates with sialic acid in a coordinated fashion in the initial stages of invasion. given the importance of these sialogycoconjugates, this review sets out various possible biological models for the interaction between the parasite and mammalian cells that possess a sialylated receptor/ligand system.

Abstract: within the framework of the eighteenth century illustration movement, the encyclopaedia acquired a fundamental importance in terms of the schematic organization of human knowledge. what this work sets out to do is to study el tesoro de la juventud o enciclopedia de conocimientos, a hispano-american version of the english encyclopaedia for children, the children's encyclopaedia, the first edition of which appeared in 1915. to be more specific, the main objective of this study is to analyze the world concept of the el tesoro de la juventud which it presents to a children's public through its different contents. we are interested in discovering, relatively long after it was created, the form by which a trusting and optimistic view of humanity was created, successful in astonishing children through the admirable scientific advances, the wonders of nature, and the progress that human creativity had been able to achieve, as well as the use it had been able to make of nature at its service.

EL MARAVILLOSO MUNDO DE EL TESORO DE LA JUVENTUD: APUNTES HISTóRICOS DE UNA ENCICLOPEDIA PARA NI OS

Abstract: En el marco del movimiento ilustrado dieciochesco, la enciclopedia cobró una importancia fundamental en cuanto organización esquemática del conocimiento humano. Lo que éste trabajo se propone es estudiar El Tesoro de la Juventud o Enciclopedia de Conocimientos, versión hispanoamericana de la enciclopedia infantil inglesa The children's encyclopaedia y cuya primera edición apareció en 1915. Más concretamente, el objetivo central de este estudio es analizar la idea de mundo que El Tesoro de la Juventud expone al público infantil a través de sus diferentes contenidos. Nos interesa descubrir, en una época ya tardía, la forma en que se elaboró una mirada confiada y optimista de la Humanidad, logrando captar con ello el asombro de los ni os a través de los admirables avances científicos, las maravillas de la naturaleza y los progresos que la creatividad humana había sido capaz de alcanzar, así como el usufructo que había sabido hacer de la naturaleza a su disposición.

Abstract: purpose: to study the pediatric cataract after trauma, it's relation to the kind of the trauma, the time elapsed between trauma and surgery and the correlation between corrected visual acuity and treatment. methods: we reviewed the medical records of all patients who presented diagnosis of traumatic cataract between august 1988 and december 2001 at the congenital cataract service of federal university of s?o paulo. results: sixty-six patients with diagnosis of pediatric cataract after trauma were studied, corresponding to an incidence of 4.80% of the total of cases attended in the service. forty-seven (71.22%) were male and 19 (28.78%) were female. forty-five (53.03%) sustained a blunt trauma, 21 (31.82%) a penetrating one, and 10 (15.15%) were not classified. the mean time between the injury and the surgery was 7 years and 6 months. the main described postoperative complications were uveitis sequels in 13 patients (21.12%) and posterior capsule opacification in 10 (15.15%). the initial and final visual acuity were obtained in 30 eyes. the mean follow-up was of two years, ranging from 1 to 96 months. conclusion: the improvement of visual acuity was statistically significant (wilcoxon test p < 0.001), being more intense in the eyes submitted to surgical treatment (p < 0.001) than in the eyes submitted to clinical treatment.

Abstract: the scope of this study is to verify the association between body fat distribution and breast cancer in women in the state of rio grande do sul, brazil. case-control methodology was used in this study, in which 100 women with a histopathological diagnosis of breast cancer were compared to an out-patient control group (400 women) between january and october 2005. the anthropometric variables collected were: body mass (kg), height, waist circumference (wc), and hip circumference. no association was found between the body mass index (bmi) and the waist/hip ratio (whr) with the occurrence of breast cancer. in relation to wc, it was observed that women with a high measurement (> 88 cm) showed 2.08 times greater chance of developing the disease than those with normal or moderate measurements (< 80 cm-87 cm). when these women were grouped by (pre- and post-) menopausal state and anthropometric variables, only wc showed an adjusted or association=3.15. the accumulation of fat in the upper part of the body (wc> 88 cm) is a predisposing factor for breast cancer, especially in pre-menopausal women.
