A new benzophenanthridine alkaloid and other bioactive constituents from the stem bark of Zanthoxylum heitzii.

Heitziquinone (7), a new benzophenanthridine alkaloid, together with five known compounds; isoarnottianamide (5), rhoifoline B (6), isobauerenol (8), 6-hydroxypellitorine (9) and sylvamide (10), were isolated as minor compounds from the hexane extract of stem bark from Zanthoxylum heitzii. Four previously reported compounds (1-4) were found, as well. Compounds 5 and 7 were both found to exist as 4:1 mixtures of two atropisomers.

Identification of chemical constituents of Zanthoxylum heitzii stem bark and their insecticidal activity against the malaria mosquito Anopheles gambiae.

Background: Zanthoxylum heitzii bark extracts have insecticidal properties and have been reported to be used against malaria in Western Africa. Previously, it has been shown that a hexane extract of the bark is toxic to adult females of the mosquito Anopheles gambiae, a malaria vector. As part of our project on the control of malaria vectors using plant extracts, the phytochemistry of Z.

Molecular epidemiology and surveillance of circulating rotavirus and adenovirus in Congolese children with gastroenteritis.

Infectious Diarrhea caused by rotavirus and adenovirus, is a leading cause of death in children in sub-Sahara Africa but there is limited published data on the diverse rotavirus genotypes and adenovirus serotypes circulating in the Republic of Congo. In this study, we investigated the prevalence of severe diarrhea caused by rotavirus A (RVA) and Adenovirus serotype 40 and 41 in Congolese children hospitalized with severe gastroenteritis. Stool samples were collected from 655 Congolese children less than 60 months of age hospitalized with acute gastroenteritis between June 2012 and June 2013.

Insecticidal activities of bark, leaf and seed extracts of Zanthoxylum heitzii against the African malaria vector Anopheles gambiae.

The olon tree, Zanthoxylum heitzii (syn. Fagara heitzii) is commonly found in the central-west African forests. In the Republic of Congo (Congo-Brazzaville) its bark is anecdotally reported to provide human protection against fleas.

Left ventricle pseudoaneurysm: contribution of multimodality imaging to the diagnosis.

Proximate, mineral and phytochemical analysis of the leaves of H. myriantha and Urera trinervis.

The vegetal materials were bought on 20th October, 2010 at the local Total market from Bacongo, South-Brazzaville. The proximate and phytochemical compositions of the leaves of H. myriantha and Urera trinervis were investigated in accordance with standard procedures.

Indigenous Muscovy ducks in Congo Brazzaville. 2. Preliminary observations on indigenous Muscovy ducks reared under moderate inputs in Congolese conditions.

To evaluate the potential of the native Muscovy ducks in Congo, a trial was conducted with closed housing, commercial feeding and veterinary care. The characterization included reproductive performance, daily weight gain, live body weight, feed conversion ratio, body live weight productivity, and meat productivity. The experimental genetic stock was bred under natural mating and natural incubation.

Indigenous Muscovy ducks in Congo-Brazzaville. 1. A survey of indigenous Muscovy duck management in households in Dolisie City.

A cross-sectional study by means of a questionnaire with open-ended questions and multiple-choice questions was used to collect data on the profile of duck keepers, husbandry practices, and performances, opportunities and constraints of Muscovy duck breeding in households (n = 88) in Dolisie city (Congo-Brazzaville). The study confirmed the common observations on traditional poultry keeping such as scavenging during the day and housing overnight. The flock size (7.

Etiology and outcome of acute renal failure in children in congo-brazzaville.

Acute renal failure (ARF) is a common problem in the Congo. This is a six-year retrospective study aiming at analyzing the etiology and the outcome of ARF at the Brazzaville's University Hospital from 1989 through 1994. One hundred and five cases of ARF (0.

Liver cysts in Congolese patients with autosomal dominant polycystic kidney disease follow a family pattern.

Background: It is now well established that at least two genes are associated with autosomal dominant polycystic kidney disease (ADPKD).

Objective: To analyse the clinical expression of ADPKD in Congolese patients and to compare ADPKD expression between families.

Methods: Following informed consent, ADPKD patients admitted to Brazzaville University Hospital (Congo) were reviewed and their relatives aged 20 years and older were screened by means of a clinical examination, abdominal ultrasound, urinalysis and determination of serum creatinine.
