Influence of Host-Related Factors and Exposure to Mosquito Bites on the Dynamics of Antibody Response to Antigens.

Humoral immunity to is acquired after repeated infections, and can lead to clinical protection. This study aimed to evaluate how human-, parasite-, and environment-related determinants can modulate the dynamics of IgG responses to after an infection. Individuals ( = 68, average age = 8.

[Recurrences of precancerous lesions after conservative treatment: Operational results after a decade in Abidjan].

Objectives: There remains a significant risk of recurrence of intraepithelial neoplasia regardless of the type of conservative treatment. The aim's work is to assess this rate.

Methods: All women's consenting who had received conservative treatment at the sites identified since for more than 12 months were included in this multicenter cross-sectional study.

Effect of isoniazid preventive therapy on risk of death in west African, HIV-infected adults with high CD4 cell counts: long-term follow-up of the Temprano ANRS 12136 trial.

Background: Temprano ANRS 12136 was a factorial 2 × 2 trial that assessed the benefits of early antiretroviral therapy (ART; ie, in patients who had not reached the CD4 cell count threshold used to recommend starting ART, as per the WHO guidelines that were the standard during the study period) and 6-month isoniazid preventive therapy (IPT) in HIV-infected adults in Côte d'Ivoire. Early ART and IPT were shown to independently reduce the risk of severe morbidity at 30 months. Here, we present the efficacy of IPT in reducing mortality from the long-term follow-up of Temprano.

[Acquired caustic vagina stenosis: Surgical outcomes of 21 cases].

Objective: To document epidemiology, causes, anatomical varieties and surgical management outcomes of caustic acquired vagina stenosis.

Methodology: Retrospective study of 21 patients involved from 1996 to 2012 at the department of obstetrics and gynecology of Yopougon's teaching hospital in Abidjan, Côte d'Ivoire. Vaginal stenosis due to genital malformation, vaginal irradiation of pelvic tumours, repair of bladder and vaginal fistulae or intersexual disorders were excluded.

A Trial of Early Antiretrovirals and Isoniazid Preventive Therapy in Africa.

Background: In sub-Saharan Africa, the burden of human immunodeficiency virus (HIV)-associated tuberculosis is high. We conducted a trial with a 2-by-2 factorial design to assess the benefits of early antiretroviral therapy (ART), 6-month isoniazid preventive therapy (IPT), or both among HIV-infected adults with high CD4+ cell counts in Ivory Coast.

Methods: We included participants who had HIV type 1 infection and a CD4+ count of less than 800 cells per cubic millimeter and who met no criteria for starting ART according to World Health Organization (WHO) guidelines.

Cervical Cancer Screening Program by Visual Inspection: Acceptability and Feasibility in Health Insurance Companies.

Objective. To assess willingness to participate and diagnostic accuracy of visual inspection for early detection of cervical neoplasia among women in a health insurance company. Patients and Method.

Spasmogenic effect of the aqueous extract of Tamarindus indica L. (Caesalpiniaceae) on the contractile activity of guinea-pig taenia coli.

The effect of aqueous extract of Tamarindus indica (AETI) was studied on the guinea pig taenia coli, due to its use for treatment of constipation in traditional medicines. AETI, at concentrations ranging from 10(-8) mg/ml to 10(-2) mg/ml, increased the spontaneous contractile activity of guinea pig taenia coli in a dose-dependent manner (EC50 = 4x10(-6) mg/ml). This activity was unaffected by atropine.

Comparative effects of developmental thiamine deficiencies and ethanol exposure on the morphometry of the CA3 pyramidal cells.

Maternal alcoholism and thiamine deficiency are frequently considered to be the causal agents of the central nervous system (CNS) damage associated with mental retardation in the offspring. For further understanding of pathological mechanisms underlying CNS damage in both disorders, histological studies were undertaken in developing rats to compare the hippocampus CA3 pyramidal cells measurements and density between three patterns of thiamine deficiency and chronic alcohol exposure. Female rats were given thiamine-deficient diet during different periods of gestation and lactation to obtain pre-, peri-, and postnatal thiamine-deficient pups.

Detection of p53 alterations in human astrocytomas using frozen tissue sections for the polymerase chain reaction.

The polymorphism of amino acid residue 72 on the human p53 tumor-suppressor gene is a useful marker for detecting intragenic loss of heterozygosity (LOH). We examined the LOH of the p53 gene in human malignant astrocytomas by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis using DNA extracted from frozen tissue sections under histologic examination. Eleven of 16 informative cases (69%) of the malignant astrocytomas were found to have LOH in the p53 gene.

[Pharmacologic effects of mansonine on arrhythmias induced in isolated rat heart].

The effect of 3 x 10(-13) M Mansonine (MSN) was observed on arrythmias induced on isolated rat heart, perfused with either hypopotassic solution, atropine solution, or MacEwen physiological saline at 18 degrees C. Generally the reversal of induced arrythmias was complete with the hypopotassic solution, and partial with the MacEwen solution at 18 degrees C. On the other hand, when atropine and MSN were combined, their effects induced heart arrest, probably due to an intracellular calcium accumulation.

[Chronic diarrhea and parasitoses in adults suspected of AIDS in the Ivory Coast].

148 adult patients with chronic diarrhoea and suspected to be HIV infected have had stool examinations. 46 are without any enteric parasite. Those detected in the others patients are Sporozoans: I.
