Resumo: Over recent years Brazil has played an increasingly active role internationally, the result of its model of integration and its foreign policy directives. The health sector is a valuable and strategic area for Brazilian technical cooperation to achieve various objectives, including its development goals. This article describes the main directives of Brazilian foreign policy, conceptually defining and characterizing South-South Cooperation, illustrated through an analysis of two Brazilian technical cooperation initiatives in healthcare: one in South America, the other in Africa. The study concludes that, irrespective of the interests and power asymmetries existing in South-South Cooperation, the objectives of this cooperation were achieved through the technical work.

Nos últimos anos, o Brasil foi ativo no âmbito internacional, tanto por seu modelo de inserção como pelas diretrizes de política externa. O setor saúde é uma ferramenta valiosa e estratégica utilizada pela cooperação técnica brasileira para lograr seus objetivos de desenvolvimento. Este artigo descreve as principais diretrizes de política externa brasileira, conceitua e caracteriza a Cooperação Sul-Sul, ilustrada mediante análise de duas iniciativas de cooperação técnica em saúde do Brasil: na América do Sul e na África. O estudo conclui que, independentemente dos interesses e das assimetrias de poder que existem na Cooperação Sul-Sul, os objetivos dessa cooperação foram alcançados por meio do trabalho técnico.

Título: Chemical composition and antibacterial activities of seven Eucalyptus species essential oils leaves
Fonte: Biol. Res;48:1-5, 2015. tab.
Idioma: en.
Resumo: BACKGROUND: In this paper, we have studied the essential oils chemical composition of the leaves of seven Eucalyptus species developed in Tunisia. Eucalyptus leaves were picked from trees growing in different arboretums in Tunisia. Choucha and Mrifeg arboretums located in Sedjnene, region of Bizerte (Choucha: E. maideni, E. astrengens et E. cinerea; Mrifeg : E. leucoxylon), Korbous arboretums located in the region of Nabeul, North East Tunisia with sub-humid bioclimate, (E. lehmani), Souiniet-Ain Drahem arboretum located in region of Jendouba (E. sideroxylon, E. bicostata). Essential oils were individually tested against a large panel of microorganisms includingStaphylococcus aureus (ATCC 6539), Escherichia coli (ATCC 25922), Enterococcus faecalis (ATCC29212), Listeria ivanovii (RBL 30), Bacillus cereus (ATCC11778). RESULTS: The yield of essential oils ranged from 1.2% to 3% (w/w) for the different Eucalyptus species. All essential oils contain α-pinene, 1,8-cineol and pinocarveol-trans for all Eucalyptus species studied. The 1,8-cineol was the major compound in all species (49.07 to 83.59%). Diameter of inhibition zone of essential oils of Eucalyptus species varied from 10 to 29 mm. The largest zone of inhibition was obtained for Bacillus cereus (E. astrengens) and the lowest for Staphylococcus aureus (E. cinerea). The essential oils from E. maideni, E. astrengens, E. cinerea (arboretum of Bizerte), E. bicostata(arboretum of Aindraham) showed the highest antibacterial activity against Listeria ivanovii and Bacillus cereus. CONCLUSION: The major constituents of Eucalyptus leaves essential oils are 1,8-cineol (49.07 to 83.59%) and α-pinene (1.27 to 26.35%). The essential oils from E. maideni, E. astrengens, E. cinerea, E. bicostatashowed the highest antibacterial activity against Listeria ivanovii and Bacillus cereus, they may have potential applications in food and pharmaceutical products.

Título: Nephropathy following Type 2 diabetes mellitus in Tunisian population / Nefropatía tras la diabetes mellitus tipo 2 en la población Tunesina
Fonte: West Indian med. j;61(9):881-889, Dec. 2012. ilus, tab.
Idioma: en.
Resumo: OBJECTIVE: The purpose was to compare the characteristics of Tunisians with Type 2 diabetes mellitus (Type 2 DM) and nephropathy with those without nephropathy. This study assessed whether or not phenotypic characteristics can predict nephropathy development in Type 2 DM. The prevalence of nephropathy in Tunisian Type 2 DM patients, and their relationship with clinical and biochemical factors as well as chronic complications of the disease were determined. METHODS: This was a cross-sectional study of patients with diabetes diagnosed between January 2008 and December 2010. Altogether, 73 Type 2 DM and 42 healthy volunteers from the Basic Health Group of Sousse, were targeted for the study. Clinical, biochemical data, as well as complications of diabetes were collected. Kidney malfunction was defined by glomerular filtration rate (GFR). RESULTS: Diabetic patients were older. Diabetic women were more likely to have higher body mass index than men (p = 0.004). Obesity was more in women than men (60/23%). Complications including hypertension and dyslipidaemia were co-associated in women. Urinary creatinine clearance in Type 2 DM patients without nephropathy was significantly lower than in healthy participants (p < 0.0001). Microalbuminuria and urinary creatinine clearance were associated only in women with Type 2 DM with nephropathy (R² = 0.95); 1.5% of Type 2 DM patients without nephropathy had GFR < 60 mL/min/1.73m² and 76% had a GFR between 60 and 89 mL/min/1.73m². Glomerular filtration rate difference between Type 2 DM patients with/without nephropathy, as well as between Type 2 DM patients with nephropathy/Type 2 DM without nephropathy, and with retinopathy was not significant. CONCLUSIONS: By analysing factors associated with nephropathy in Type 2 DM Tunisian patients, this study demonstrated their susceptibility to nephropathy. In addition, retinopathy is potentially associated with incipient nephropathy in Type 2 DM Tunisian patients.

OBJETIVO: El propósito fue comparar las características de los tunesinos con diabetes mellitus tipo 2 (DMT2) y nefropatía, con aquéllos que no padecen nefropatía. Este estudio evaluó la posibilidad de saber si las características fenotípicas pueden predecir el desarrollo de una nefropatía en pacientes de DMT2. Se determinó la prevalencia de la nefropatía en los pacientes tunesinos con DMT2, y su relación con factores clínicos y bioquímicos, así como las complicaciones crónicas de la enfermedad. MÉTODOS: Se realizó un estudio transversal de pacientes con diabetes diagnosticada entre enero de 2008 y diciembre de 2010. En total, 73 voluntarios con DMT2 y 42 saludables del Grupo Básico de Salud de Sousse, fueron escogidos para el estudio. Se recogieron los datos clínicos y bioquímicos, así como las complicaciones por diabetes. El grado de mal funcionamiento renal fue determinado por la tasa de filtrado glomerular (GFR). RESULTADOS: Los pacientes diabéticos tenían más edad. Las mujeres diabéticas presentaban una mayor probabilidad de tener un índice de masa corporal más alto que los hombres (p = 0.004). Hubo mayor obesidad en las mujeres que en los hombres (60/23%). Las complicaciones - incluyendo hipertensión y dislipidemia - estuvieron co-asociadas en las mujeres. La depuración de la creatinina urinaria en los pacientes de DMT2 sin nefropatía fue significativamente más baja (p < 0.0001) que en los participantes saludables. La microalbuminuria y la depuración de la creatinina urinaria estuvieron asociadas en las mujeres con DMT2 con nefropatía (R² = 0.95); 1.5% de los pacientes con DMT2 sin nefropatía, tuvo una tasa GFR < 60 mL/min/1.73m² y 76% tuvo una GFR entre 60 y 89 mL/min/1.73m². La diferencia de la tasa de filtrado glomerular entre los pacientes de DMT2 con/sin nefropatía, así como entre los pacientes de DMT2 con nefropatía/DMT2 sin nefropatía, y con retinopatía, no fue significativa. CONCLUSIONES: Analizando factores asociados con la nefropatía en pacientes tunesinos con DMT2, este estudio demostró que estos últimos son susceptibles a la nefropatía. Además, la retinopatía se halla potencialmente asociada con la nefropatía incipiente en los pacientes tunesinos que padecen DMT2.

Título: Lipids, proteins, phenolic composition, antioxidant and antibacterial activities of seeds of peanuts (Arachis hypogaea l) cultivated in Tunisia
Fonte: Biol. Res;46(3):257-263, 2013. ilus, graf, tab.
Idioma: en.
Resumo: Fatty acid composition of peanut seed oil in four varieties cultivated in Tunisia showed that linoleic (C18:2), oleic (C18:1) and palmitic (C16) acids account for more than 84% for Chounfakhi and Massriya and for more than 85% of the total fatty acids of Trabilsia and Sinya seed oil respectively. Seed oil contents were significantly different (P ≤ 0.05) and did not exceed 48%. The study of total phenolics revealed that Chounfakhi contained more total phenolics (2.1 mg GAE/g DW), followed by the Massriya and Sinya cultivars (1.35 mg GAE/g DW for each); Trabilsia presented the lowest total phenolic content with 1 mg GAE/g DW. Considerable antiradical ability was found, especially in the Trabilsia peanut seed cultivar (IC50 = 1550 μg/ml), the Massriya and Sinya cultivars had, respectively, 720 and 820 mg/ml IC50. In the Massriya variety the sterol fraction showed antibacterial activity against Listeria ivanovii, Listeria inocua, Pseudomonas aeruginosa, Staphylococus aureus, Enterococcus hirae and Bacillus cereus.

Título: Research of the origin of a particular Tunisian group using a physical marker and Alu insertion polymorphisms
Fonte: Genet. mol. biol;34(3):371-376, 2011. ilus, tab.
Idioma: en.
Resumo: The aim of this study was to show how, in some particular circumstances, a physical marker can be used along with molecular markers in the research of an ancient people movement. A set of five Alu insertions was analysed in 42 subjects from a particular Tunisian group (El Hamma) that has, unlike most of the Tunisian population, a very dark skin, similar to that of sub-Saharans, and in 114 Tunisian subjects (Gabes sample) from the same governorate, but outside the group. Our results showed that the El Hamma group is genetically midway between sub-Saharan populations and North Africans, whereas the Gabes sample is clustered among North Africans. In addition, The A25 Alu insertion, considered characteristic to sub-Saharan Africans, was present in the El Hamma group at a relatively high frequency. This frequency was similar to that found in sub-Saharans from Nigeria, but significantly different from those found in the Gabes sample and in other North African populations. Our molecular results, consistent with the skin color status, suggest a sub-Saharan origin of this particular Tunisian group.

Título: Does minor histocompatibility antigen HA-1 disparity affect the occurrence of graft-versus-host disease in tunisian recipients of hematopoietic stem cells?
Fonte: Clinics;65(11):1099-1103, 2010. tab.
Idioma: en.
Resumo: INTRODUCTION: Minor histocompatibility antigen HA-1 (MiHAg-HA-1) disparity between a patient and his or her human leukocyte antigen (HLA) genoidentical donor has been widely associated with an increased risk of graft-versus-host disease following allogeneic hematopoietic stem cell transplantation. OBJECTIVE: To examine the effect of HA-1 disparity on the incidence of both acute and chronic graft-versus-host disease in Tunisian recipients of hematopoietic stem cells. METHODS: A total of 60 patients and their 60 respective sibling hematopoietic stem cell donors were enrolled in this study. All patients prophylactically received cyclosporine A and/or methotrexate for graft-versus-host disease. An HA-1 genotyping assay was performed with the SSP-PCR method, and HLA-A*0201- and/or HLA-A*0206-positive samples were identified using the Luminex HLA typing method. RESULTS: The Luminex HLA typing assay showed that 54 patients were positive for either the HLA-A*0201 or HLA-A*0206 alleles. Among these cases, six pairs were mismatched for MiHAg-HA-1. Both acute and chronic graft-versus-host disease occurred in four mismatched patients (Fisher's p-values were 0.044 and 0.170, respectively). A univariate logistic regression model analysis showed that only acute graft-versus-host disease may be affected by recipient MiHAg-HA-1 disparity (p: 0.041, OR: 6.727), while chronic graft-versus-host disease correlates with both age and recipient/donor sex mismatch (p: 0.014, OR: 8.556 and p: 0.033, OR: 8.664, respectively). CONCLUSION: Our findings support previously reported data suggesting a significant association between HA-1 disparity and the risk of acute graft-versus-host disease following hematopoietic stem cell transplantation.
