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...
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...
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...

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...
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...
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...
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...
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...
ABSTRACT Moisture solid transfer during osmotic dehydration of three banana varieties was investigated.
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.
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...
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...
ABSTRACT Purpose: Nasopharyngeal cancer (NPC) is a malignant tumor which is commonly associated with Epstein Barr virus (EBV). Two genotypes of EBV, genotype 1 and genotype 2, which are geographically restricted, are implicated in the pathogenesis of NPC. This study aimed at detecting and characterizing EBV genotypes involved in the pathogenesis of NPC in Ghana. Experimental design: Whole blood and biopsy samples were collected from 55 patients diagnosed of NPC by CT scan and endoscopy at the...
ABSTRACT A simple inexpensive chemical route has been identified and used to synthesize cupric oxide nanoparticles suitable for photovoltaic applications. X-ray diffraction analysis showed the synthesized nanoparticles to be a pure cupric oxide phase. The particle size and particle size distribution of the cupric oxide nanoparticles were obtained by transmission electron microscopy (TEM) whereas the crystallite size and crystallite size distribution were obtained by X-ray diffraction peak bro...
