Hiv-1 Drug Resistance Profiles Of Ghanaian Women On Antiretroviral Therapy After Prevention Of Mother-To child Transmission (Pmtct)

ABSTRACT From 2007 to 2011 HIV-positive pregnant women in Ghana, were given a combination of Zidovudine and Lamivudine as prophylaxis during pregnancy and a single dose of Nevirapine upon the onset of labour towards the prevention of mother to child transmission (PMTCT) of HIV. Since these women were subsequently given the same antiretrovirals (ARVs) to manage their HIV infection, there was, therefore, the need to determine the HIV-1 drug resistance profiles in such patients in Ghana. This s...

Hearing Loss Among Patients Receiving Antituberculosis Treatment

ABSTRACT Background: Tuberculosis therapy is characterized by many side effects including hearing loss. It has been documented that the use of aminoglycosides for TB treatment is the cause of the associated hearing impairment. The consequential effect of hearing impairment on the patient is high. This has its long-term socio-economic effect (social isolation and stigmatization) on patients, families and public health in general. Hearing loss can compromise treatment compliance and also affec...

A Taxonomic, Ecological And Nutritional Study Of Porphyra Capensis Kützing Populations From The Namibian Coast

ABSTRACT The Namibian Porphyra capensis Kützing was studied as very little was known of its taxonomy, ecology, phylogeny or nutritional status. It was hypothesized that it was phlogenetically related to the South African P. capensis as they share common ancestry. DNA was extracted from thalli and partial sequences obtained from their 18SrDNA and ITS regions. GenBank sequences of interest were incorporated, alignments made and phylogenetic trees were generated using MEGA 5.1. The results show...

Cyber Security Risk Management And Threat Control Model (Csrm-Tcm): A Study Carried Out To Enhance The Protection Of Information In The Namibian Public Service

ABSTRACT The persistent threats of the cyber environment drives organizations to adopt risk management as a crucial practice of minimizing dangers to their information assets. However, focusing on technology alone to address these risks is no longer sufficie nt. IT governance which enables senior managers to align and integrate technology with business strategies through clear policy development and good practice of IT control is essential. The Namibian Public Service (NPS) currently lacks po...

Head Tilt Classification Using Fft-Pca/Svm Algorithm

ABSTRACT The complexity of a face’s components originates from the constant variations in the facial component that occur with respect to time. Notwithstanding these variations, humans recognize a person very easily using physical characteristics such as face, voice, gait, etc. Automatic face recognition deals with extracting these essential features from an image, placing them into a suitable representation and performing some kind of recognition on them. This study presents an assessment...

Lyapunov Functions In Epidemiological Modeling

Abstract In this mini thesis, we study the application of Lyapunov functions in epidemiological modeling. The aim is to give an extensive discussion of Lyapunov functions, and use some specific classes of epidemiological models to demonstrate the construction of Lyapunov functions. The study begins with a review of Lyapunov functions in general, and their usage in global stability analysis. Lyapunov’s “direct method” is used to analyse the stability of the disease-free equilibrium. More...

Single Nucleotide Polymorphisms In Insulin-Like Growth Factor (Igf) Genes And Their Associations With Growth In Local Guinea Fowls (Numida Meleagris) Of Ghana

ABSTRACT Due to the pivotal role of Insulin-like Growth Factor 1 (IGF1) and Insulin-like Growth Factor 2 (IGF2) in growth regulation of poultry, the IGF1 gene (gIGF1) and IGF2 gene (gIGF2) in guinea fowl were examined as candidate genes for early growth in helmeted guinea fowls (Numida meleagris) from three populations of Northern Ghana (TPNG). Keets hatched from eggs collected from 32 sample locations comprising 11 subpopulations across three main populations located in Upper East Region, U...

Determinants Of All-Cause Maternal Mortality In Ghana: A Multivariate Decomposition Analysis Of 2007 And 2017 Ghana Maternal Health Surveys

ABSTRACT Background Maternal mortality has seen a significant decline in Ghana over last decade. Stakeholders and government continue to invest in strategic policies aimed to further decrease the ratio of maternal mortality. To achieve the desired results, interventions must be tailored toward specific factors in order to further strengthen the remedy to this health menace. Even though, there has been a decline over the years, international target and standards yet to be achieved. Method Ana...

Entomological Assessment Of Lymphatic Filariasis Transmission In Selected Communities In Ghana

ABSTRACT The resurgence of lymphatic filariasis (LF) infection after several rounds of Mass Drug Administration (MDA) has been the main reason behind constant monitoring of treatment. The MDA is designed to interrupt transmission by reducing microfilaraemia in a community to a threshold that local vectors may not be able to pick up microfilariae (MF) during a blood meal. The current study has been carried out to determine whether transmission had actually been interrupted following stoppage o...
