The phytochemical screening showed that the (MO) extract contained many compounds such as polyphenols, polyterpenes, sterols, reducing sugars, and hydrolysates tannins. The MICs of MO extract for microbial strains is 0.73 mg/ml for , , 7.

Telomere Dysfunction in Pediatric Patients with Differences/Disorders of Sexual Development.

Unlabelled: Differences/Disorders of sex development (DSDs) are conditions in which the development of chromosomal, gonadal, and anatomical sexes is atypical. DSDs are relatively rare, but their incidence is becoming alarmingly common in sub-Saharan Africa (SSA). Their etiologies and mechanisms are poorly understood.

Is Response to Genotoxic Stress Similar in Populations of African and European Ancestry? A Study of Dose-Response After Irradiation.

Exposure to genotoxic stress such as radiation is an important public health issue affecting a large population. The necessity of analyzing cytogenetic effects of such exposure is related to the need to estimate the associated risk. Cytogenetic biological dosimetry is based on the relationship between the absorbed dose and the frequency of scored chromosomal aberrations.

Hepatitis B virus (HBV) infection amongst children in Senegal: current prevalence and seroprotection level.

Introduction: Hepatitis B virus (HBV) infection is highly endemic in Senegal. HBV vaccine of all children has been introduced in 1999 and included in the Expanded Programme on Immunization in 2004. The aim of this study was to assess the HBV prevalence and immunity status against HBV amongst children in Senegal.

Biological Dosimetry Network in Africa: Establishment of a Dose-Response Curve Using Telomere and Centromere Staining.

Purpose: Biological dosimetry, based on the relationship between the absorbed dose after exposure to ionizing radiation and the frequency of scored aberrations, has been and continues to be an important tool for estimating the dose after exposure. Dicentric chromosomes are considered to be the most specific and sensitive aberration related to radiation exposure. Here, we established the dose-response curve following in vitro irradiation of circulating lymphocytes from healthy donors from three African countries after scoring unstable chromosomal aberrations.
