Abstract/Overview Most odour baits designed to attract host-seeking mosquitoes contain carbon dioxide (CO2), which enhances trap catches, given its role as a mosquito fight activator. However, the use of CO2 is expensive and logistically demanding for prolonged area-wide use.
Abstract Seagrass beds occur globally in both intertidal and subtidal zones within shallow marine environments, such as bays and estuaries. These important ecosystems support fisheries production, attenuate strong wave energies, support human livelihoods and sequester large amounts of CO2 that may help mitigate the effects of climate change. At present, there is increased global interest in understanding how these ecosystems could help alleviate the challenges likely to face humanity and the...
Abstract distribution width (RDW) measures anisopoikiloytosis and is readily reported by haematology analysers as a complete blood count parameter. The utility of RDW as a diagnostic marker of haemoglobinopathies in Kenya remains undetermined and undocumented. Objective: This study aimed to determine the diagnostic efficacy of RDW in discriminating haemoglobinopathy and haemoglobinopathy-free cases in Kenya. Methods: The case-control study used randomly selected haematology analyser outputs ...
Abstract Background Sulfadoxine-pyrimethamine (SP) is the only anti-malarial drug formulation approved for intermittent preventive treatment in pregnancy (IPTp). However, mutations in the Plasmodium falciparum dhfr (Pfdhfr) and dhps (Pfdhps) genes confer resistance to pyrimethamine and sulfadoxine, respectively. Here, the frequencies of SP resistance-associated mutations from 2005 to 2018 were compared in samples from Kenyan children with malaria residing in a holoendemic transmission region...
Abstract/Overview We identified 672, 374, and 379 CYPs proteins encoded by the CYPs genes in Gossypium hirsutum, Gossypium raimondii, and Gossypium arboreum, respectively. The genes were found to be distributed in all 26 chromosomes of the tetraploid cotton, with chrA05, chrA12, and their homeolog chromosomes harboring the highest number of genes. The physiochemical properties of the proteins encoded by the CYP450 genes varied in terms of their protein lengths, molecular weight, isoelectr...
Abstract Comparing of morphological character variation within taxa continues to play an important role in improving species inventories. Using morphometrical and non-meristic morphological adult characters, the diversity of the genus Ptychadena in Taita Hills was studied. Comparative material from elsewhere was not used, and therefore species names were only provisionally allocated to the taxa identified. Available names were discussed on the basis of comparisons with morphological data fro...
Sex estimation models are specific to populations and cannot be generalized due to genetic and environmental variabilities. This retrospective cross-sectional study, conducted between January and September 2023 at the Tamale Teaching Hospital, included 119 (50.9 %) females and 115 (49.1 %) males aged 23–82 years. Measurements, including manubrium length (M), manubrium width (MW), sternal body length (B), combined manubrium and sternal body lengths (CL), corpus sterni width at first sternebr...
Abstract: Mole-rats from the family Bathyergidae are endemic to Africa, this family exhibits a continuum of sociality, comprising both solitary and social species. Sociality is related to the degree of aridity and the distribution of the underground food resource. All the members of the bathyergid family are strictly subterranean, and occur in a niche which is devoid of light cues and thermally buffered from ambient and surface extremes. Since vision is redundant in a lightless environment, ...
Abstract: The identification of specific compounds in onion and garlic bulbs and agronomic practices would lead to a better understanding of the physiological responses to onion consumption. Phytochemicals are biologically active compounds in plants that have some beneficial importance in industrial and medicinal sciences. The present study was undertaken to investigate the role of roasting and cooking on phytochemical compositions of onion (Allium cepa L) and garlic (Allium sativum L.) bulb...
Abstract: The ABO and Rh blood groups are the most important blood groups despite the long list of several other blood groups discovered so far. The ABO and Rh blood group frequencies vary worldwide and are not found in equal frequencies even among ethnic groups. In this study, a cross-sectional survey was used to assess the phenotypic, allelic and genotypic frequency distribution of ABO and Rh blood groups and possible associations with intestinal parasitic infections in Babile district, Ea...
Abstract: ABO and Rh blood groups vary worldwide and are not distributed uniformly even among related ethnic groups. The study was aimed at having information on the allelic frequency, genotypic frequency of ABO and Rh blood group phenotypes among the students of Bora Secondary School. From a total of 719 students 240 voluntary participant students were `selected for this study. Among them, 134 (55.83%) were males and 106(44.17%) were females. Blood samples were collected by pricking the mid...
Abstract: Biogas is one of the alternative energy sources that can be produced from animal wastes and crop residues through anaerobic digestion. This study evaluated biogas production from corn stalk with chicken manure in solo and mix ratios under anaerobic condition at 38ºC using batch digester. The Parameters studied included total solids (TS), volatile solids (VS), pH, organic carbon (%), total nitrogen and C: N ratio. After incubation for 30 days, gas production was measured daily for ...
Abstract: Production of biogas through anaerobic digestion of organic waste materials provides an alternative environmentally friendly renewable energy. Water hyacinth is one of the fastest growing aquatic weed known to man. The objective of this study was to determine biogas yield using water hyacinth as a sole substrate and co- digestion with poultry dropping. Anaerobic digestion (AD) was done using the two substrates in five mix ratio was evaluated under mesophilic conditions (380C) using...
Abstract: Malaria is one of the major public health problems in many tropical and subtropical developing countries such as Ethiopia. The objective of this study was to determine malaria trends, prevalence and to assess the control practices practiced by people in Melka Belo Woreda, in Eastern Hararghe Zone, Oromia Regional State, Ethiopia. A cross sectional survey study was carried out from April to May 2016. Health records of malaria for the last eight years (2008-2015) were obtained from M...
Abstract: Intestinal parasitic infections are the major public health problems in many developing countries including Ethiopia. The study was conducted with an objective to determine the prevalence and intensity of intestinal parasite infections among school children enrolled in Ahimed Gurey Elementary School, Jigjiga town, Somali Region, eastern Ethiopia. A total of 422 (219 males and 203 females) school children within age range of 5-19 years were selected by stratified random sampling met...
