STATISTICAL ANALYSIS OF FACTORS AFFECTING MATERNAL MORTALITY IN GHANA

ABSTRACT This study evaluated the relationship between possible medical and social factors affecting maternal deaths. A conceptual framework was developed to help identify, classify, model and resolve these factors (by implementing the recommendations). A generalized linear model was fixed using the ‘R’ statistical analysis software. Three data sets (2016 and 2013 data sets on maternal mortality, and a data set on the causes of maternal deaths) were used in the analysis, which showed wide...

THE POTENTIAL ROLE OF NOCTURNAL BITING INSECTS IN THE TRANSMISSION OF MYCOBACTERIUM ULCERANS IN THE AKUAPEM-SOUTH DISTRICT

ABSTRACT Several hypotheses have been made about the possible mode of transmission of Mycobacterium ulcerans (M. ulcerans) and one of these is the role of insects as possible vectors. Although studies have been conducted extensively on aquatic insects and mosquitoes, limited work has been done on the prevalence of M. ulcerans in other insects. This study investigated the potential role of nocturnal biting insects as vectors of M. ulcerans. Nocturnal insects were sampled from Buruli Ulcer ende...

ESTIMATION OF CONTRALATERAL BREAST DOSE FOR TANGENTIAL BREAST IRRADIATION USING GAFCHROMIC FILM EBT2

ABSTRACT The dose to the contralateral breast for tangential breast irradiation has been estimated using Gafchromic films EBT2. The data collected consisted of measurements taken with anthropomorphic female Rando phantom. The EBT2 films were scanned and read using ScanMaker 9800XL plus and ImageJ software. A calibration curve was constructed using fourth – order polynomial fit to the data and a calibration equation was obtained from the graph which was used to convert the grey values into d...

PHENOTYPIC CHARACTERIZATION AND IN VITRO RESPONSE OF LYMPHOCYTES OF GHANAIAN CHILDREN WITH BURKITT’S LYMPHOMA TO PLASMODIUM FALCIPARUM MALARIA ANTIGENS

Abstract It has been shown in epidemiological studies that malaria may play a role in the pathogenesis o f endemic Burkitt’s Lymphoma (eBL). The contribution o f m alaria to the pathogenesis o f eBL is believed to be due to the imbalances in the immune regulation during malaria infection. Studies have shown a loss o f CTL function due to a shift o f the immune responses from T h l towards Th2 T-cell function during malaria infection. This study sought to investigate the phenotypes o f perip...

SYNTHESIS AND CHARACTERIZATION OF ZINC OXIDE NANO-PARTICLES FOR PHOTOVOLTAIC APPLICATION

ABSTRACT The low total conversion efficiency of dye sensitized solar cells have caused researchers to improve the individual components of the cell. This work aims to produce zinc oxide nanoparticles to help improve absorption and also reduce recombination in the photo anode of the dye-sensitized solar cell (DSSC). In this work, zinc oxide nanoparticles were produced using the hydrothermal synthesis technique and the annealing effect was conducted on the prepared samples. The samples prepared...

DISTRIBUTED NUMERICAL MODELLING OF HYDROLOGICAL/HYDROGEOLOGICAL PROCESSES IN THE DENSU BASIN

ABSTRACT: The study was undertaken to develop a Densu basin integrated hydrological model capable of describing the major hydrological processes occurring in the land phase of the hydrological cycle and computation of water balance in the Densu river basin. Inadequate information on the hydrological processes as well as the regional water balance in the basin has adversely affected the sustainable development, assessment and efficient management of the basin’s water resources. A physi...

PARAOXONASE 1 (PON 1) Q192R GENOTYPE DISTRIBUTION IN GHANAIANS WITH TYPE II DIABETES MELLITUS

ABSRACT Background: Recent studies have indicated PON 1 polymorphism to be associated with cardiovascular-related diseases such as diabetes mellitus but varied reports have been provided from such association studies. In Ghana, there is no such information on PON 1 polymorphism in disease situations; except one instance reported in non-diseased Ghanaians. The present study has therefore provided baseline information on PON 1 Q192R polymorphism in Ghanaians with type II Diabetes Mellitus. Main...

CHEMICAL MODIFICATION AND COWPEA FORTIFICATION OF MAIZE

ABSTRACT The high utilization and consumption levels of maize in developing countries call for the investigation of new methods of processing to introduce variety as well as improve the functionality and nutrient quality of maize-based foods. This study was carried out to determine the effect of nixtamalization, fermentation and cowpea fortification on maize and to identify the dominant microflora in fermented nixtamalized maize. The effect of cooking and lime concentration was determined usi...

COMPARATIVE ANALYSIS OF HIGHER-RISK SEXUAL BEHAVIOR IN TEN SUB-SAHARAN AFRICA COUNTRIES BASED ON THEIR THREE MOST CURRENT DEMOGRAPHIC AND HEALTH SURVEYS

ABSTRACT Background Higher-Risk Sexual Behavior (H-RSB) is an act whereby people engage in sexual activities with multiple partners and do not consistently use condom. This practice is very common in sub-Saharan Africa (SSA). Though the prevalence of HIV is decreasing in sub-Saharan Africa H-RSB keep increasing in the region. Objective This study investigated and compared the trends and determinants of Higher-Risk Sexual Behavior among ten countries in SSA. Method Data for this study was obta...

ERYTHROCYTE INVASION MECHANISMS OF PLASMODIUM FALCIPARUM CLINICAL ISOLATES FROM GHANAIAN CHILDREN

ABSTRACT Clinical manifestations of Plasmodium falciparum infections are caused by invasion of erythrocytes by malaria parasites, a process mediated by multiple receptor-ligand interactions. Antibodies against some parasite ligands significantly inhibit parasite growth in vitro, demonstrating that these interactions may be good targets for the development of an effective blood stage vaccine. This study was aimed at investigating the erythrocyte receptors used by P. falciparum isolates in Ghan...

MOISTURE SOLID TRANSFER DURING OSMOTIC DEHYDRATION OF BANANA (MUSA SAPIETUM) VARIETIES

ABSTRACT Moisture solid transfer during osmotic dehydration of three banana varieties was investigated.

Modelling the flow of water in Stratified Layers of Sand

ABSTRACT The phenomenon of detection of flow of water in porous media of different porosities with porosity ratio, is similar to the fact that there is deviation in fluid flow in a pair of media of different densities.

PATIENT DOSE ASSESSMENT OF ADULT AND PAEDIATRIC CHEST COMPUTED TOMOGRAPHY EXAMINATION: COMPARISON BETWEEN AUTOMATIC EXPOSURE CONTROL AND FIXED TUBE TECHNIQUES.

ABSTRACT This study was to examine procedures used to estimate radiation dose delivered to adult and paediatric patients undergoing computed tomography (CT) examination and propose alternative and more efficient ways to establish body CT protocols for optimum protection of patient for clinical use. Automatic exposure control (AEC) and fixed tube current (FTC) techniques were used for Polymethylmethacrylate (PMMA) dosimetry phantoms in a Siemens emotion 16-slice multidetector computed tomograp...

A SURVEY OF THE NUTRITIONAL STATUS OF WOMEN AT OTINIBI, A PERI-URBAN COMMUNITY NEAR ACCRA

ABSTRACT The purpose of this study was to assess the effects of women’s life circumstances on their health and nutritional status. The study included women of reproductive age (15 - 45 years old) and 74 women took part in the study. Study-specific semi-structured questionnaires were used to collect dietary, socioeconomic, demographic and workload data. Urinary and random blood glucose determinations were used to test for the prevalence of diabetes mellitus. The subjects had mean (± SD) ran...
