Introduction: Low birth weight (LBW) is defined by the World Health Organization (WHO) as a birth weight strictly below 2500 g, whatever the term of pregnancy. It constitutes a major public health problem, both in developed and developing countries, due to its magnitude and its strong association with infant morbidity and mortality. Main objective was to study the factors associated with the occurrence of small-for-gestational-age newborns in Douala. Methodology: We carried out a cross-sectional analytical study with prospective data collection using a technical pretested sheet in the maternity wards of the Douala General Hospital, the Laquintinie Hospital, and the District hospitals of Deido, Nylon and Bonassama over a period of 4 months (January to April 2020). We were interested in any newborn, born alive, vaginally or by cesarean section, of low weight, seen in the first 24 hours from a full-term single-fetal pregnancy whose mother had given her consent. Our sampling was consecutive and non-exhaustive. We excluded newborns whose term was unclear and those with congenital malformations or signs of embryo-foetopathy. Data collection was done using survey sheets. Statistical analyzes were carried out with CS Pro 7.3 and SPSS version 25.0 software. The Student, Chi-square and Fischer tests were used to compare the means of the variables, the percentages with a significance threshold P value Results: During the study period, 305 full-term newborns were included, divided into 172 boys and 133 girls. The percentage of small-for-gestational-age newborns was 9.8%;after multivariate analysis by logistic regression to eliminate confounding factors, we found maternal factors associated with small for gestational age newborns;maternal age less than 20 years, primiparity, gestational age (37 - 38), a delay in prenatal visits greater than 14 weeks, anemia in pregnancy, positive toxoplasmosis serology in pregnancy, a body mass index of Conclusion: Our study revealed the potenti

OBJECTIVE To observe the effects expression and activation on biological cancer stem cells. of blocking CD133 gene characteristic of the colon METHODS CD133＋ colon cancer stem cells （CCSCs） were separated from EpCAMhigh CD44＋ CCSCs through fluorescenceactivated cell sorting （FACS）. The proliferation, the capability of spherical cell formation, neoplasia, and the expression of ABCG2 mRNA of CD133＋ CCSCs were observed after the CD133＋ CCSCs were infected with LV-CD133shRNA. CD133 negative cells were isolated from EpCAMhigh CD44＋ CCSCs with FACS, and the CD133 proteins in CD133- cells were detected with Western blot. RESULTS CD133＋ CCSCs were isolated from EpCAMhigh CD44＋ CCSCs using FACS, and they accounted for 89.2% in the stem cells. In the experimental group, after the CD133＋ CCSCs were knocked down by LV-CD133shRNA RNAi, the growth pattern of the cells in the stem cell culture changed into adherent growth from suspended growth, and couldn＇t generate spherical cells. Results of MTT assay showed that the CD133＋ CCSCs infected with LV-CD133shRNA grew slowly, compared to the cells in the control groups. There was a decrease in the cloning efficiency. The infected cells were transplanted into the BALB/c nude mice. During the observation, no neoplasia was found in the CD133＋ cells infected with LV-CD133shRNA. The level of ABCG2 mRNA expression was lowered greatly （P 〈 0.01）. CD133- cells were obtained from the EpCAMhigh CD44＋ CCSCs using FACS, in which the expression of CD133 protein was positive. CONCLUSION CD133 retains the biological characteristics of the colon cancer stem cells.

Introduction: Anthropometry applied to newborns is a reliable indicator of the quality of fetal growth. The latter is influenced by genetic, racial and nutritional factors varying from one population to another, explaining why a standard cannot be applied to all populations. research question: should the Caucasian frame of reference be dogmatically applied in our African context? Multicenter studies are therefore necessary;hence the interest of this work, the main objective of which was to describe the anthropometric profile of full-term newborns in the city of Douala. Methodology: We carried out a cross-sectional study with an analytical aim and prospective data collection in the maternity wards of the Douala General Hospital, Laquintinie Hospital, District hospitals of Deido, Nylon and Bonassama over a period of 4 months (January to April 2020). We were interested in any newborn, born alive, vaginally or by cesarean section, seen in the first 24 hours from a full-term single-fetal pregnancy whose mother had given consent. We excluded newborns whose term was unclear and those with congenital malformations or signs of embryo-foetopathy. Data collection was done using structured and pre-tested survey sheets. The study variables were obstetric and anthropometric. Statistical analyzes were carried out with CS Pro 7.3 and SPSS version 25.0 software. The Student, Chi-square and Fischer tests were used to compare the means of the variables, the percentages with a significance threshold P value Results: During the study period, 305 full-term newborns were included, divided into 172 boys and 133 girls. The average anthropometric parameters of the full-term newborn in the city of Douala were: average weight: 3305 grams, average height: 49.8 centimeters, average head circumference: 34.6 centimeters, average upper arm circumference: 11.3 centimeters, circumference average thoracic: 32.8 centimeters.
