Diagnóstico molecular da toxoplasmose: revis?o

Abstract: toxoplasmosis infects millions of people worldwide. the prevalence of human infection in many countries is estimated in approximately 40% to 50%. in brazil this rate increases up to 80%, depending on the studied area. the majority of human hosts present the infection as asymptomatic carriers. serologically negative pregnant women may contribute to a higher morbidity of the disease due to parasite transmission to the fetus via placenta if acute toxoplasmosis is acquired during pregnancy. the diagnosis of acute toxoplasmosis has relied on the evidence of circulating anti-parasite igm. the high sensitivity of the present serological techniques has brought results of residual igm eventually confounding final diagnosis. in this scenario, the molecular techniques, such as the polymerase chain reaction (pcr), may promote a better interpretation of the real status of human/parasite interaction, although they have not been extremely validated for routine use in the diagnosis of toxoplasmosis.

Abstract: The aim of this research was to study the frequency of intestinal parasites in patients from three communities belonging to the state of Lara, Venezuela. A rural community, Miracuy, Andrés Eloy Blanco municipality, a suburban community, Agua Viva, Palavecino municipality and a third community (control group) consisting of samples made of patients from Barquisimeto, a city in the Iribarren municipality of the state of Lara. After the application of the coprological techniques to each stool sample, a total of 503 samples was obtained. From those samples, 35,8% belonged to the urban group, 48,9% to the suburban group and 15,3% to the rural one. The group with the highest proportion of intestinal parasites was the rural one (80,5%). The most common parasites were the protozoa, being Blastocystis hominis the most prevalent in the three groups, followed by Giardia lamblia and Endolimax nana. Among helminths, Ascaris lumbricoides was the most common metazoan, followed by Trichuris trichiura. It is considered that the high prevalence rates in these parasitic diseases are associated with lack of information, as well as living conditions in marginal and rural population, including the lack of enforcement of hygiene, health education, adequate water storage, poor sewage systems and garbage disposal, among others. Funded by UCLA project CDCHT-013-ME-2008.
BABESIOSIS HUMANA POR Babesia sp. (Piroplasmorida: Babesiidae). REPORTE DE UN CASO EN EL ESTADO LARA.

Abstract: We report a human case of Babesia sp., Which is a frequent coccidian parasite in cattle, dogs and cats but rare inhumans. These female patient four years of age whose mother reported anemia, approximately two months duration,concomitant hyperoxia and generalized weakness, and it is transferred to the Social Security Hospital, being evaluated bya general practitioner, who said tests laboratory, which showed the presence of parasites in blood. In view of these resultsis referred to the Section of Medical Parasitology at UCLA, where he performed peripheral blood smears observed bymorphological and morphometric analysis, the presence of Babesia sp., An obligatory intraerythrocytic parasite
Calidad de cuidado materno: una comparación entre bebés prematuros en cuidado madre canguro y bebés a término en cuidado regular

Abstract: the purpose of this study was to examine the potential impact of an intervention program (kangaroo mother care, kmc) on maternal sensitivity in a sample of high-risk adolescent mothers. two mother-infant groups were compared: adolescent mothers with their preterm baby in kangaroo care and adolescent mothers with their full-term baby in regular care. naturalistic observations at the home environment were conducted to assess maternal quality of care. no significant differences were found between both groups of dyads. results are in line with the notion that kmc seems to play a protective role for adolescent mothers and their premature babies, given the additional risk factor of prematurity when compared to the full term group. these preliminary findings are stimulating and support further inquiry into the effects of kmc on maternal sensitivity particularly in high-risk populations.

Tres espacios narrativos más allá de Macondo (ángel, Fayad, Espinosa)
Figueroa,Cristo Rafael;
Tabula Rasa , 2007,
Abstract: this article tries to visualize three of the narrative trayectories that colombian novelistics adopted after “the autumn of the patriarch” by gabriel garcía márquez: exploration of new literary forms to show the consequences of colombian violence in female infancy and the role of women in this issue (estaba la pájara pinta sentada en el verde by albalucía ángel); search for neorealist aesthetics to focus the complex processes and consequences of bogotá’s modernization (los parientes de ester by luis fayad); and the option of neo-baroque writing capable of putting into perspective and questioning hegemonic conceptions about colonial history (la tejedora de coronas by germán espinosa).

Abstract: Este artículo pretende visualizar tres de los trayectos narrativos que adopta la novelística colombiana posterior a El oto o del patriarca de Ggarcía Márquez: exploración de nuevas formas literarias para evidenciar las secuelas de la violencia colombiana en la infancia femenina y el papel de la mujer dentro de la misma (Estaba la pájara pinta sentada en el verde limón de Albalucía ángel); búsqueda de estéticas neorrealistas para focalizar los complejos procesos y consecuencias de la modernización de Bogotá (Los parientes de Ester de Luis Fayad); y opción por una escritura neobarroca capaz de relativizar y cuestionar concepciones hegemónicas sobre la historia colonial (La tejedora de coronas de Ggermán Espinosa)

Wound Healing: From Epidermis Culture to Tissue Engineering  [PDF]

CellBio (CellBio) , 2012, DOI: 10.4236/cellbio.2012.12003
Abstract: The skin is the largest organ of the individual, being the interface between the body and the microenvironment. In severely burned patients and other diseases, the physiological processes of wound healing are not sufficient to complete the closure of their wounds. The in vitro culture of autologous epidermis, which has represented the beginning of Tissue Engineering, is a valuable tool for the treatment of these patients. Keratinocytes can be cultured and stratified in vitro, and an entire epidermal sheet can be obtained. The epidermis cells can be amplified in the laboratory from a skin sample to obtain a surface equivalent to that required for each patient. This technology was first used clinically in 1981 and in Argentina since 1991. Wound repair is a complex process that involves dermal and epidermal cells, extracellular matrix, soluble factors and the sum of interactions between them, providing physical, biological and chemical keys capable of guiding cell function. Seeking to improve the results obtained with cultured epidermis, tissue engineering was directed towards the development of substitutes that not only involve epidermis but also the dermal component. The tissue engineered skin and its therapeutic applications reported in this review demonstrate the feasibility and effectiveness of these approaches. It represents a clear benefit in wound healing. Now, focus must be directed on the development of new scaffolds, developed by different technologies, such as polymer science, or nanotechnology, able to be used as templates to direct the growth of cells, in an attempt to better regenerate the lost skin.
