Fernand W. Nana,Adama Hilou,Jeanne F. Millogo,Odile G. Nacoulma
Pharmaceuticals , 2012, DOI: 10.3390/ph5060613
Abstract: This paper describes a preliminary assessment of the nutraceutical value of Amaranthus cruentus (A. cruentus) and Amaranthus hybridus (A. hybridus), two food plant species found in Burkina Faso. Hydroacetonic (HAE), methanolic (ME), and aqueous extracts (AE) from the aerial parts were screened for in vitro antioxidant and xanthine oxidase inhibitory activities. Phytochemical analyses revealed the presence of polyphenols, tannins, flavonoids, steroids, terpenoids, saponins and betalains. Hydroacetonic extracts have shown the most diversity for secondary metabolites. The TLC analyses of flavonoids from HAE extracts showed the presence of rutin and other unidentified compounds. The phenolic compound contents of the HAE, ME and AE extracts were determined using the Folin–Ciocalteu method and ranged from 7.55 to 10.18 mg Gallic acid equivalent GAE/100 mg. Tannins, flavonoids, and flavonols ranged from 2.83 to 10.17 mg tannic acid equivalent (TAE)/100 mg, 0.37 to 7.06 mg quercetin equivalent (QE) /100 mg, and 0.09 to 1.31 mg QE/100 mg, respectively. The betacyanin contents were 40.42 and 6.35 mg Amaranthin Equivalent/100 g aerial parts (dry weight) in A. cruentus and A. hybridus, respectively. Free-radical scavenging activity expressed as IC 50 (DPPH method) and iron reducing power (FRAP method) ranged from 56 to 423 μg/mL and from 2.26 to 2.56 mmol AAE/g, respectively. Xanthine oxidase inhibitory activities of extracts of A. cruentus and A. hybridus were 3.18% and 38.22%, respectively. The A. hybridus extract showed the best antioxidant and xanthine oxidase inhibition activities. The results indicated that the phytochemical contents of the two species justify their traditional uses as nutraceutical food plants.

Molecules , 2008, DOI: 10.3390/molecules13030581
Abstract: A total of fourteen (14) species of wild edible fruits from Burkina Faso wereanalyzed for their phenolic and flavonoid contents, and their antioxidant activities usingthe DPPH, FRAP and ABTS methods. The data obtained show that the total phenolic andtotal flavonoid levels were significantly higher in the acetone than in the methanol extracts.Detarium microcarpum fruit had the highest phenolic and the highest flavonoid content,followed by that of Adansonia digitata, Ziziphus mauritiana, Ximenia americana andLannea microcarpa. Significant amounts of total phenolics were also detected in the otherfruit species in the following order of decreasing levels: Tamarindus indica > Sclerocaryabirrea > Dialium guineense > Gardenia erubescens > Diospyros mespiliformis > Parkiabiglobosa > Ficus sycomorus > Vitellaria paradoxa. Detarium microcarpum fruit alsoshowed the highest antioxidant activity using the three antioxidant assays. Fruits with highantioxidant activities were also found to possess high phenolic and flavonoid contents.There was a strong correlation between total phenolic and flavonoid levels and antioxidantactivities.

Abstract:

The aim of this study was to contribute to strengthening the efficiency in the treatment of the salivary gland tumours in the Stomatology and Maxillo-facial surgery service at the University Hospital Centre/Yalgado OUEDRAOGO of Ouagadougou. It has been a retrospective and descriptive study covering seven (7) years [January 2006-December 2012] on epidemiology and the treatment of 54 cases of the salivary glands tumours histologically confirmed. Benign tumours (non-malignant tumours were prevalent (61.11% of cases). The annual incidences were 4.71 cases for non malignant tumours and 3 cases for malignant tumours. The average age was 34-45 years for non malignant tumours and 44-33 years for malignant ones. In both groups, the tumour was discovered lately with an average 32-48 months before consulting in case of non malignant tumours and 18-29 months for malignant tumours. The location of non malignant tumours was very often the parotid (42.42%), under mandible gland (27.28%). Malignant tumours very often concerned the parotid (76.18%) and the under mandible gland (14.29%). The histology has revealed that pleomorphic adenoma was the leading type of non-malignant tumours (93.94% of cases) whereas carcinoma was predominant in malignant tumours (80.95% of cases). Long term track keeping was difficult and it has been complicated by the loss of contact with some patients. The low living standard, the time wasted before consulting, limited human resources and therapeutic means constitute handicaps to the treatment in our African context.

Abstract: Objective: To study the sexual risk behaviors and their determining role in sexually transmissible infection (STI) and HIV among students of the University of Ouagadougou. Methodology: It was a descriptive and analytical single pass cross-sectional study from June 22 to July 21 2010 at the University of Ouagadougou. A cluster sampling in two stages was adopted to form a population of 762. Data were collected using a standardized written questionnaire completed by individual interview after informed consent. Results: The average age of students was 24.2 ± 2 years old for men and 23.7 ± 2 years old women. Singles represented 95.1% of students. The students were not scholarship grantees in 90.6% of the sample. Knowledge about STIs was average in 60.2% of cases. In total 33.65% of the students admitted to having had multiple sexual partners, 19.57% had sex with prostitutes, 34.62% had unprotected sex, 4% practiced sodomy without condoms and 3.1% of students had sex in group with one partner. In multivariate analysis, male gender was the determining factor associated with multiple sexual partner (OR = 3.30 95% CI = 2.19 to 4.95) and relations with prostitutes with an odds ratio of 16.13 (95 = 6.87% to 37.8%). The female gender was the determining factor associated with not using a condom with odds ratio of 1.5 (95% CI = 1.01 to 2.16). Conclusion: There are many risk behaviors for HIV transmission among students of the University of Ouagadougou. The urgent implementation of specific prevention programs to benefit this population is essential.
The language of Burkinabè masks: an esoteric discourse?

Tydskrif vir letterkunde , 2007,
Abstract: Le language des masques burkinabè : un discours ésotérique ? Les masques burkinabè sont un langage a priori ésotérique compte tenu de leur caractère initiatique, mythique et secret. Cependant ils sont aussi exotériques en tant qu’expression sociale et religieuse communautaire. Ils sont un langage parce qu’ils ont une fonction expressive. Ils sont des messages pour l’ensemble de la communauté où ils se manifestent. Leur antinomie, ésotérisme/exotérisme, explique leurs deux aspects. Premièrement, les masques ont un volet réservé à une élite qui y accède uniquement par enseignement secret (ésotérisme) et qui détient les mythes explicatifs et les techniques de fabrication. Deuxièmement, les masques ont une fonction socio-religieuse qui est communautaire et populaire c’est-à-dire ouverte à la connaissance de tous (exotérisme) : ils expriment les croyances fondamentales, les prières d’expiation, de demande de prospérité et de paix de toute la communauté. Cela est dit à tout le monde. Beaucoup de signes utilisés dans les manifestations des masques appartiennent du reste au code symbolique lisible par tous (les formes animales ou imaginaires des masques, leurs espaces d’évolution, leurs gestes, leurs danses, les dispositions du public …). Mots clés : masques burkinabè, langage, exotérisme, ésotérisme. Tydskrif vir Letterkunde Vol. 44 (1) 2007: pp. 181-190 Article text in French

Abstract: ential impact of chronotype on weekday and weekend sleep timing and duration Original Research (3441) Total Article Views Authors: Stephanie E Roepke, Jeanne F Duffy Published Date September 2010 Volume 2010:2 Pages 213 - 220 DOI: http://dx.doi.org/10.2147/NSS.S12572 Stephanie E Roepke1, Jeanne F Duffy1,2 1Division of Sleep Medicine, Department of Medicine, Brigham and Women’s Hospital, Boston, MA, USA; 2Division of Sleep Medicine, Harvard Medical School, Boston, MA, USA Abstract: Most recommendations are that adults should obtain 7–8 hours of sleep per night, although there are individual differences in self-reported sleep need. Chronotype (preference for early or late sleep timing), in combination with social demands, may affect the ability to obtain adequate sleep. This questionnaire study assessed perceived sleep need and self-reported sleep timing and duration during the week and on the weekend with respect to chronotype in visitors to the Museum of Science in Boston. Increasing age was associated with greater morningness. After adjusting for age, we found no significant association between chronotype and self-reported sleep need, or between chronotype and weekday sleep duration. However, we did find that greater eveningness was associated with a larger gap between self-reported sleep need and weekday sleep duration. On weekends, greater eveningness was associated with a longer sleep duration and greater extension of sleep, with the sleep extension achieved by later wake times. Together, these findings suggest that evening types accumulate a sleep debt during the week, despite reporting a similar sleep need and duration as morning types, and evening types then attempt to make up for that lost weekday sleep on the weekends. Studies of sleep need and sleep duration should take chronotype into account, and studies of chronotype may be confounded by the association between age and morningness, and must account for this potential confound in selection criteria and/or analysis.

Abstract: La afinidad por la narrativa la comparten los investigadores de muchas disciplinas. Los estudios sobre narrativa son una opción para las enfermeras investigadoras interesadas en utilizar métodos cualitativos, para analizar sus experiencias en enfermería, salud y enfermedad. En este trabajo discutimos los retos metológicos y epistemológicos, las tensiones y oportunidades que hemos encontrado en el proceso para desarrollar interpretaciones de una narrativa feminista, y la aproximación de los estudios de narrativa, basados tanto en perspectivas feministas como en enfermería.

Research Journal of Medical Sciences , 2012,
Abstract: The total phenolics and the flavonoids contents of stem barks and leaves of Parkia biglobosa harvested at different periods of the year, on 2 different areas of Burkina Faso (Yako and Lèna), were determined. The total phenolics were extracted according to Harborne s method and also by the means of a soxhlet apparatus. The determination of the phenolics contents was conducted with 8 extracts using tannic acid as standard. The flavonoids contents of the 8 extracts were also determined, using quercetin as a reference substance. The results showed that the total phenolics contents vary significantly all year round at the same area and also from Lèna to Yako. They also revealed that the flavonoids contents of the leaves harvested at Yako ranged from 1.49-1.80% throughout the year. The results also confirmed that the leaves contain more flavonoids than the barks. Antioxidant activity was determined by the means of 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay. The results showed effectiveness with a radical inhibition ranging from 25.53±3.56-55.449±4.53 mg mL-1. The antibacterial assays on gram positive Staphylococcus aureus showed that the hydroalcoholic extract of stem bark harvested in May at Yako was the most effective of all the extracts.

Abstract: OBJECTIVE: To assess the impact of the National Immunization Days (NIDs) on measles vaccine coverage in Burkina Faso in 1998. METHODS: During the week after the campaign, in which measles vaccine was offered to children aged 9-59 months in six cities regardless of vaccination history, a cluster survey was conducted in Ouagadougou and Bobo Dioulasso, the country?s two largest cities. Interviewers visited the parents of 1267 children aged up to 59 months and examined vaccination cards. We analysed the data using cluster sample methodology for the 1041 children who were aged 9-59 months. FINDINGS: A total of 604 (57%) children had received routine measles vaccination prior to the campaign, and 823 (79%) were vaccinated during the NIDs. Among those who had previously had a routine vaccination, 484 (81%) were revaccinated during the NIDs. Among those not previously vaccinated, 339 (78%) received one dose during the NIDs. After the campaign, 943 (91%) children had received at least one dose of measles vaccine. Better socioeconomic status was associated with a higher chance of having been vaccinated routinely, but it was not associated with NID coverage. CONCLUSION: The mass campaign enabled a substantial increase in measles vaccine coverage to be made because it reached a high proportion of children who were difficult to reach through routine methods.
