A Study Of The Nutrition And Health Of Children In The Gold Coast A Field And Laboratory Study

INTRODUCTION Despite wide interest in the nutrition and health of children in underdeveloped areas of the world, countries in Africa have been neglected by individuals and groups in the United States as sites for dietary and health studies. Reasons for this doubtless lie elsewhere than in a lack of interest. Such study not only offers the possibility of providing information needed by the indigenous population, but also information concerning the nutritive needs of children in relation to con...

Deconstructing Invasion Phenotype Switching In Plasmodium Falciparum

ABSTRACT The extensive redundancy in the use of invasion ligands by Plasmodium falciparum, and its unique ability to switch between invasion pathways have hampered vaccine development. The Dd2 and W2mef strains of P. falciparum have been shown to change from sialic acid (SA)-dependent to SA-independent phenotypes when selected on neuraminidase-treated erythrocytes. Following an observation of increasing ability of Dd2 to invade neuraminidase-treated cells when cultured for several weeks, a sy...

Effect Of Two Kinds Of Solvent On Chemical Composition Of Cymbopogon Citratus Oil

ABSTRACT The experiment was designed to determine the effect of two different solvent (N-hexane and petroleum ether) on chemical composition of lemongrass oil. The oil was extracted from lemongrass using Nhexane and petroleum ether using soxhlet extraction method. The chemical composition of essential oil obtained were analyse using GC-MS machine. The result shows 4.4% of oil were obtained from lemongrass using N-hexane and 4.9% were obtained using petroleum ether. The composition analysed b...

Antinutritional Composition Of Securidaca Longepedunculata (Violet Tree)

ABSTRACT The antinutritional composition of leafs and stem bark s. longepedunculata were investigated using standard analytical methods. The leafs and stem bark of S. longepedunculata was air dried and the sample was pulverized for the determination of anti-nutritive contents. The antinutritional continents viz phytate, oxalate, nitrate and cyanide were determined in this investigation. Nitrate content was significantly (p

Evaluation Of Storage Control Point And Implicated Pathogens On Fast Moving Consumer Goods - Ogun And Lagos States As Case Study

ABSTRACT Ensuring food safety to protect public health remains a significant challenge in both developing and developed countries and food borne illness prevention system will depend on the extent of food safety control in place through food production, processing and distribution, keeping food at safe temperature and using safe water and raw materials. These stages of production are some of the important points determining food safety. The high level of bacterial contamination leading to in...

Evaluation Of Some Nutritional, Physicochemical And Phytochemical Parameters Of Dioscorea Rotundata (White Yam) Flesh And Peels Exposed To Four Different Storage Patterns In Nigeria.

ABSTRACT The hue and cry of food insecurity in Nigeria prompted the curiosity of this study. This study investigates the evaluation of some nutritional, physicochemical and phytochemical parameters on Dioscorea rotundata (white yam) flesh and peels exposed to four different storage patterns in Nigeria. Four storage patterns and 20 tubers of yam were used for this study. The yams were grouped into the four storage patterns: Open Sided, Yam Barn, Heap on Floor and Platform Storage, and the ana...

Comparism Analysis Between Microscopy And Filariasis Strip Test (FTS)

ABSTRACT Lymphatic filariasis (LF) is caused by infection with threadlike worms called Wuchereria bancrofti. There had been different methods of diagnosing Filariasis. The two major diagnosing method is the Filariasis Test strip and the Microscopy test. This project is to compare the efficiency between the Microscopy test and Filariasis Test Strip (FTS) Night blood sampling method collected between the hours of 10pm – 2am and Filariasis test strip is done same hours using 2 drop of blood a...

Assessment Of Coastal Ecosystems In The Greater Cape Three Points Area Towards Its Designation As Marine Protected Area In Ghana

ABSTRACT Coastal ecosystems sustain local and national fisheries livelihoods through a range of ecosystem services (ES) they provide. Five of these coastal ecosystems, located in two communities within the Greater Cape Three Points (GCTP) area—Princess Town (PT) and Cape Three Points (C3P)—were assessed to develop a scheme for establishing Marine Protected Area (MPA). To conduct an integrated assessment, the study employed the Community Participatory Mapping and Assessment of ecosystems a...

Management Of Indigenous Medicinal Plants In Nigeria Using Phenological Information

ABSTRACT Available information on medicinal plants indicates habitat loss and has heightened the need for more proactive conservation strategies. Conservation efforts in this direction resulted in an ecopharmacological survey in the West African sub-region by three countries (Nigeria, Ghana and Republic of Benin) to assess frequently used medicinal plants. The result of the socio-economic study based on utilization pattern regionally was used to produce a list of ten topmost frequently used a...

IgG Enzyme-Linked Immunosorbent Assay (ELISA) for immunodiagnosis of Schistosoma haematobium infected subjects living in an endemic Nigerian village

ABSTRACT Schistosoma haematobium infects school children in areas where the disease is endemic. This study was carried out to determine the reliability of IgG Enzyme-Linked Immunosorbent Assay (ELISA) as an immunodiagnostic tool, using whole antigen derived from Schistosoma eggs. Children of school going age living in Ipogun village, in south western Nigeria; a schistosomiasis endemic community; were used in this study. The sensitivity of the IgG ELISA in detecting positive cases was 68.0% an...

EFFECTS OF DRYING METHODS ON NUTRIENT CONTENTS OF Moringa oleifera (Lam.) LEAVES

ABSTRACT The study was carried out to determine the effect of drying methods on the nutrient contents of Moringa oleifera at the Agric. Chemical Laboratory (Usmanu Danfodiyo University Sokoto) and The Energy Research Field of Sokoto Energy Center, Sokoto. Fresh leaves were collected and cleaned then dried using different drying methods viz. shade drying, solar drying, oven drying and sun drying. The treatments were analyzed for proximate and mineral contents using standard methods. Sta...

ABUNDANCE OF MOSQUITO SPECIES WITHIN SOKOTO METROPOLIS

ABSTRACT The study was conducted to determine the abundance of mosquito species within Sokoto metropolis. Three (3) locations, which are Danbuwa, Gobirawa and GidanIgwai, in three (3) Local Government Areas, namely; DangeShuni, Sokoto South and Sokoto North Local Government Areas respectively, were sampled out of the five (5) Local Government Areas that make up Sokoto Metropolis were sampled. A total of 341 Mosquitoes species belonging to two genera were collected. The genera identified ...

DETERMINATION OF PLASMODIUM FALCIPARUM AND HOST GENETIC FACTORS THAT AFFECT THE EFFICACY OF THE ARTEMISININ-BASED COMBINATION PARTNER DRUGS USED IN GHANA

ABSTRACT Malaria is one of the major causes of morbidity and mortality in sub-Saharan Africa, especially in children under 5 years and pregnant women. The use of Artemisinin-based combination therapy (ACT), which is a combination of a fast-acting artemisinin derivative and a relatively slow-acting partner drug, is used for malaria treatment in disease-endemic areas. The ACT partner drugs in Ghana are lumefantrine (LUM), amodiaquine (AQ), and piperaquine (PQ). Plasmodium falciparum isolates wi...

Evaluation of host humoral antibody production against Plasmodium falciparum recombinant circumsporozoite antigen in Nigerian children

ABSTRACT Background & objectives: The challenge of malaria and efforts targeted at developing malaria vaccines triggered this study on the reactivity of IgG and its subclasses in the test serum specific to CSP. This work was directed at assessing the influence of age and gender on host humoral antibody against Plasmodium falciparum recombinant circumsporozoite antigen in Nigerian children. Methods: In all, 67 serum samples (>10,000 parasites/μl of blood) collected from malaria-infected chi...
