ABSTRACT The physico-chemical characterization, macrobenthic invertebrates and biomarkers of oxidative stress as indicators of heavy metal (Cu, Fe, Pb, Mn and Zn) contamination in Ologe Lagoon, Nigeria were investigated from January, 2007 - December, 2008. Biomarkers of oxidative stress [Catalase (CAT), Glutathione S- transferase (GST), Superoxide Dismutase (SOD), Reduced Glutathione (GSH) and Malondialdehyde (MDA)] activities were evaluated in Pachymelania aurita exposed to sublethal concen...
Abstract Background: Plasmodium falciparum resistance to anti-malarials is a major drawback in effective malaria control and elimination globally. Artemisinin-combination therapy (ACT) is currently the key first-line treatment for uncomplicated falciparum malaria. Plasmodium falciparum genetic signatures at pfmdr-1, pfcrt, and pfubp-1 loci are known to modulate in vivo and in vitro parasite response to ACT. The objective of this study was to assess the distribution of these resistance gene m...
ABSTRACT The Kunene region is an arid region with extreme environmental conditions. Understanding how environmental conditions affect bat activity, number and distribution is important for assessing activity and abundance. Monthly bat activity and the effect of environmental factors (temperatures, moon phase) on bat activity were recorded to elucidate factors influencing the distribution of bats. Wildlife Acoustic SM2 detectors were used to detect the bat activity from three sites, altitudina...
ABSTRACT Bats are present and they play unique ecological roles in various habitats in Namibia. Yet the patterns of species richness and composition of bats associated with these habitats within different biomes in Namibia still remain unknown. Bats are also important carrier hosts and transmitters of zoonotic viruses of public health significance including old and emerging hantaviruses. The burden of hantavirus disease is globally well-documented but this remains unknown and unrecognised in ...
A b s t r a c t Despite widespread and its local available as a naturalized hedge and shade plant, the potential of Trichilia emetica was not utilized in soap making by the majority of local community in various parts of Dodoma, Tanzania. This study aimed to assess the quantity (yields) and quality (Acid Values (AVs), %Free Fatty Acids (%FFAs) and Saponification Values (SVs) of seed oil from water plant (T. emetica), suitable for soap making application. Solvent extraction method was used dur...
Abstract Introduction: Trypanosome infections result into trypanosomosis in cattle and this is an infection detrimental to pastoralist income. The patterns of transmission are thought to be influenced by ecological factors including wildlife and land cover. We assessed the influence of the relative abundance of wildlife and land cover (cultivation and habitat type) on the presence of trypanosome infections in replicated cattle herds of the Maasai Steppe.
ABSTRACT Bacillus anthracis is a soil-borne bacterium and the causative agent of the disease anthrax which commonly infects herbivorous animals. The disease is transmitted via three routes of infection: ingestion, cutaneous or inhalation of spores. This study investigated the seasonality of dust bathing as a possible contributor to inhalational anthrax in zebra, blue wildebeest and African elephants, in relation to the seasonality of anthrax mortalities in Etosha National Park. Most anthrax ...
.Abstract. A cross-sectional study design in two primary schools in Ibadan and Akure was used to determine the prevalence or urinary schistosomiasis, and the human humeral immune response to schistose antigens in individuals with malaria co-infection. Urine samples were collected from 163 children, while 112 gave blood samples. Malaria parasitaemia was determined by microscopy after Giernsa staining and schistdsomiasis by centrifugation technique. Serum samples were analyzed for antibodies ...
Abstract: The draft nuclear genome sequence of the snail-transmitted, dimorphic, parasitic, platyhelminth Schistosoma mansoni revealed eight genes encoding proteins that contain the Universal Stress Protein (USP) domain. Schistosoma mansoni is a causative agent of human schistosomiasis, a severe and debilitating Neglected Tropical Disease (NTD) of poverty, which is endemic in at least 76 countries. The availability of the genome sequences of Schistosoma species presents opportunities for bioi...
ABSTRACT Cerebral malaria (CM) is known to be the most severe complication of Plasmodium falciparum infection. Despite effective anti-parasitic treatment, it remains a major cause of morbidity and mortality in infected children. Sequestration of infected red blood cells in the brain microvasculature, occlusion of blood flow, activation and subsequent damage of the endothelium are hallmarks of the pathogenesis of CM. This study sought to quantify and compare time course levels of cEPC and othe...
ABSTRACT Malaria is still a public health burden. With the recent reports of artemisinin resistance in Plasmodium falciparum coupled with the low efficacy of the RTS, S vaccine currently under a WHO-recommended pilot malaria vaccine implementation programme (MVIP), there is the need to continue identifying new targets by functionally characterizing some of the ~60% of the parasite’s genes with unknown functions. This will foster the identification of viable vaccine and possible drug targets...
ABSTRACT There have been debates whether insects that visit cashew during the flowering and fruiting periods are the same. The main problem arises as whether the insects that visit the plant during the flowering are the same that visit during the fruiting period. Field survey was conducted in ten farms in the Northern Region from December 2014 to April 2015 to identify and assess insects taxa on cashew in farms close to natural forest and farms away from natural forest, during cashew floweri...
ABSTRACT Inclusive education is a form of delivering educational services to all children irrespective of their physical characteristics, linguistic or racial background in regular schools. It has to do with commitment by government to educate every child to the maximum extent appropriate in the school and classroom he or she could otherwise attend. Inclusive education has become a developmental approach to the learning needs of all children, youth and adults, especially those who are vulnera...
ABSTRACT The purpose of the study is to find out the extent to which teachers faithfully commit themselves to the fidelity approach to curriculum implementation in transacting the Core English curriculum. The main design used in the study was descriptive survey. The study covered all the seven public senior secondary schools in Sunyani District in the Brong Ahafo region ofGhana. The sample comprised 150 students and all the 31 teachers of English. The number of students selected from each sch...
