    Background: The study aims to examine the association between lifestyle habits and breast cancer risk in a Moroccan population.Methods: This is a case-control study conducted at the Mohammed VI Centre for cancer treatment in Casablanca.Results: The results highlighted that family history of breast cancer (OR=5.73) and alcohol consumption                     (OR=3.76) were positively associated with breast cancer. Analysis of anthropometric parameters showed that the risk of developing breast cancer is estimated at 1.78 in overweight women and 2.39 in obese women compared to those of normal weight. The risk of developing breast cancer is estimated at 1.82 for women with a WC greater than 88 cm and 1.70 for women with a WHR greater than 0.85. At age 10, the risk is 1.60 for women with a large figure compared to women with a small figure. However, at age 40, the average body shape relative to the lean body was associated with a decreased risk of breast cancer. In addition, the data confirmed that physical activity participation decreases with age; in childhood and adolescence, women are more active while in post-menopause, women become moderately active. Being very active in childhood, peri-menopause and post-menopause seems to be a protective factor against the occurrence of breast cancer.Conclusions: The study showed that the risk of breast cancer is potentially high in elderly women, overweight women and women with a family history of cancer. This risk was increased by behavioral factors such as toxic habits and physical inactivity

    Monoclonal antibodies are essential tools in molecular and cellular immunology research. They have essentially replaced the polyclonal antibodies in identifying blood groups and detecting cell markers and pathogenic agents. The aim of the present study is to produce monoclonal antibody identifying the ABO blood groups using the murine hybridoma technology. An anti-A monoclonal antibody A907 was selected and estimated for its use in the manufacture of a reagent anti-A. The selected antibody specifically reacts with A1, A2/sub>, A1B and A2B erythrocytes. It does not recognize B, O, A3 and Ax erythrocytes. The A907 monoclonal antibody can be used in blood grouping in association with a reagent recognizing the A weak phenotypes.Key words: Anti-A monoclonal antibodies, murine myeloma cells, haemagglutination.African Journal of Biotechnology Vol. 4 (8), pp. 844-84

    Background: The purpose of the study is to investigate hormonal risk factors and their impact on the development of this cancer.Methods: This is a case-control study conducted at the Mohammed VI Centre for Cancer Treatment in Casablanca.Results: The average age of the patients is 50.43 years with a standard deviation of 11.21. Exposure to endogenous estrogens appears to have an impact on the occurrence of breast cancer in the population. The early age of menarche in patients is on average 13.31±1.69 years compared to 13.65±1.54 years in controls, with a significant difference (p = 0.01). Parity is on average 2.54 children in cases versus 2.94 in controls with a significant difference (p = 0.02). Regarding the distribution of the cumulative duration of breastfeeding, 19.3% of patients compared to 12.3% of controls breastfed their children for less than one year; 80.7% of cases compared to 87.7% of controls breastfed their children for more than one year (OR=0.58; 95% CI: 0.35 - 0.97; P trend=0.03). In addition, hypovitaminosis D was noted in 2.3% of patients compared to 0.3% of controls with OR=7.14; 95% CI: 0.87 - 58.39; P trend=0.06. In addition, the supply of exogenous estrogen would also be incriminated. The risk of breast cancer appears to be influenced mainly by oral contraceptive use, which was found in 60% of cases vs. 41.3% of controls with OR=2.07; 95% CI: 1.50 - 2.86; P trend=0.0001.Conclusions: The results highlighted that breast cancer risk is highly dependent on early and prolonged exposure to estrogenic impregnation. This effect would be modulated by ovarian activity, puberty or menopause age, parity and breastfeeding

    Introduction: le cancer du sein reprĂ©sente un enjeu majeur de santĂ© publique. L´objectif de ce travail est de dĂ©crire le profil sociodĂ©mographique, les habitudes toxiques et le profil alimentaire des patientes atteintes du cancerdu sein traitĂ©es au centre Mohammed VI pour le traitement des cancers de Casablanca. MĂ©thodes: il s´agit d´une Ă©tude transversale portant sur 305 patientes atteintes de cancer du sein nouvellement diagnostiquĂ©es. RĂ©sultats: l´âge moyen des patientes est 50 ans. Cinquante-six pourcent (plus prĂ©cisĂ©ment 55,7%) de nos patientes sont mariĂ©es et 12,8% sont veuves. Parmi les femmes interrogĂ©es, 83% sont des femmes au foyer, 63,3% rĂ©sident dans un milieu urbain et 47,9% sont analphabètes. Concernant les habitudes toxiques de nos patientes, seules 5,9% des femmes enquĂŞtĂ©es ont dĂ©clarĂ© avoir consommĂ© de l´alcool et une minoritĂ© a dĂ©clarĂ© ĂŞtre ex-fumeuse ou fumeuse, avec respectivement 4,3% et 2,3%. Quant au rĂ©gime alimentaire, nos patientes consommaient le pain et la viande rouge avec une frĂ©quence moyenne respectivement de 8,26 et 5,84 fois/semaine, et enfin les produits laitiers avec une frĂ©quence moyenne de consommation allant de 3,55 Ă  4,57 fois/semaine. Par ailleurs, nos patientes consommaient plus de pomme de terre et des fruits frais, avec respectivement des moyennes de frĂ©quence de 5,74 et 5,38 fois/semaine. Le thĂ© reste Ă©galement la boisson la plus consommĂ©e avec une moyenne de frĂ©quence très Ă©levĂ©e de 8,12 fois/semaine. Conclusion: Ă  la lumière de nos rĂ©sultats, la plupart des femmes interrogĂ©es, sont des femmes au foyer, analphabètes et rĂ©sident dans un milieu urbain. Plusieurs aliments sont frĂ©quemment consommĂ©s par nos patientes. En revanche, la consommation de substances psychoactives telles l´alcool et le tabac est faible. Des Ă©tudes analytiques type cas-tĂ©moins sont nĂ©cessaires afin d´établir d´éventuelles associations entre ces facteurs de risque et le cancer mammaire

    Fenugreek seeds estrogenic activity in ovariectomized female rats

    No full text
    The estrogenic activities of fenugreek seeds (Trigonella foenum-graecum L.), widely used in traditional pharmacopoeia, are reflected in the uterus of ovariectomized female rats, with a slight increase in dry and wet weight, a thickening of the stroma and the uterine epithelium and the development of the endometrial glands. In the vagina, the estrogenic action is shown through an increase in the epidermal cell number and a tendency to keratinization, leading to vaginal opening

    Introduction: le cancer colorectal constitue un problème majeur de santĂ© publique. L’objectif de notre Ă©tude est d’analyser le profil Ă©pidĂ©miologique, nutritionnel, clinique et anatomo-pathologique des cancers colorectaux recrutĂ©s au CHU de Casablanca. MĂ©thodes: notre Ă©tude cas-tĂ©moins a portĂ© sur les patients pris en charge pour un cancer colorectal durant l’annĂ©e 2015, comparĂ©s Ă  des tĂ©moins non suivi pour un cancer. RĂ©sultats: l’âge moyen des patients Ă©tait de 56,65 ans avec un Ă©cart type de 14,64. Le type histologique le plus frĂ©quent chez nos patients Ă©tait reprĂ©sentĂ© par l’adĂ©nocarcinome LieberkhĂĽnien avec une proportion de 82 %. L’analyse de l’indice de masse corporelle a permis de retrouver une obĂ©sitĂ© chez 50% des patients contre 20% des tĂ©moins et un diabète chez 19% des patients versus 8% des tĂ©moins (p < 0,019). Par ailleurs, l’étude du rĂ©gime alimentaire des patients comparĂ© Ă  celui des tĂ©moins semble montrer que la moyenne de la frĂ©quence de consommation hebdomadaire de viandes rouges est plus Ă©levĂ©e chez les patients que chez les tĂ©moins (4,24 vs 3,26; p = 0,009) et inversement pour la consommation du poissons (0,97 contre 1,76; p = 0,0001). En revanche, la moyenne de consommation des lĂ©gumes et des fruits est plus faible chez les patients que chez les tĂ©moins (5,00 vs 9,50; p = 0,0001). Concernant les habitudes toxiques de nos patients, 32% des patients Ă©taient fumeurs vs 13 % des tĂ©moins. Conclusion: nos rĂ©sultats montrent que la prise de conscience Ă  propos du rĂ©gime alimentaire et des changements dans nos habitudes de vie pourrait rĂ©duire l’incidence du cancer colorectal et par consĂ©quent la mortalitĂ© et la morbiditĂ©
