Drinking water, cowpea and maize grains were sampled in some potentially exposed agro-ecological areas in Togo and analysed for their contamination by some common organochlorine pesticides. A total of 19 organochlorine pesticides were investigated in ten subsamples of maize, ten subsamples of cowpea and nine subsamples of drinking water. Analytical methods(More)
OBJECTIVES We compared the reactivity of IgG1 and IgG2a antibodies in mouse sera after infection with virulent RH and low-virulent S273 and Beverley strains of Toxoplasma gondii against RH SAG1 recombinant p30 (rp30) and synthetic SAG1 peptides. METHODS Infected mouse serum samples were collected 9 days after infection, and the level of total IgG, IgG1(More)
Seventeen monoclonal antibodies (MAbs) were previously established against the heavy chain (Hc) of botulinum type E neurotoxin in BALB/c mice immunized with the type E toxoid. Five MAbs (LE15-5, LE34-6, EK19-7, EK21-4, and AE27-9) showed toxin-neutralizing activity in mice. Two of the five MAbs, EK19-7 and EK21-4, recognized the regions located at amino(More)
We report on a patient having McCune-Albright syndrome (MAS) associated with non-autoimmune hyperthyroidism associated with thyrotoxic crisis. Polyostotic fibrous dysplasia developed at age 8, and café-au-lait pigmentation was noted on the skin. At age 18, he developed hyperthyroidism with multiple adenomatous changes. The hyperthyroidism had been(More)
We have studied mutagenic specificity of an abasic site by the yeast-transformation procedure using an oligonucleotide containing a single furan-type abasic site. The recipient yeast used was deficient in the major AP endonuclease (apn1). Sequence analysis of the transformants suggested that dATP was incorporated most frequently opposite the abasic site,(More)
This study was carried out to evaluate the contamination severity of Lake Togo by organochlorinated pesticides historically used in agriculture and in health programs against disease vectors in public health. A total of 48 samples of sediments and 48 samples of water were seasonally collected. For both sediment and water 3 samples per site were collected at(More)
