An overview of advances in bioinformatics and its application in functional genomics
(2010-04-28)Bioinformatics is the scientific discipline that is concerned with the efficient management and useful interpretation of large scale biological information. Functional genomics aims at mapping DNA sequences and the ... -
Pathogenic Escherichia coli and food handlers in luxury hotels in Nairobi, Kenya
(Elsevier, 2009-05)Background: The epidemiology and virulence properties of pathogenic Escherichia coli among food handlers in tourist destination hotels in Kenya are largely uncharacterized. Method: This cross-sectional study among ... -
Performance Evaluation of Proximal Sensors for Soil Assessment in Smallholder Farms in Embu County, Kenya
(MDPI, 2016-08)Four proximal soil sensors were tested at four smallholder farms in Embu County, Kenya: a portable X-ray fluorescence sensor (PXRF), a mobile phone application for soil color determination by photography, a dual-depth ... -
A perspective on proteomics: current applications, challenges and potential uses
(Academic Journals, 2010-08)Biological sciences are experiencing an ongoing information revolution. Proteome-wide functional classification using bioinformatics approaches is becoming an important method for revealing unknown protein functions. ... -
Phenomic characterization of Crotalaria germplasm for crop improvement
(Cabi, 2021-03)Background: Diversifcation of global food systems through exploration of traditional varieties and wild edible plant species is a focal mitigation strategy for food security worldwide. The present study determined the ... -
Phenotypic Diversity of Doum Palm (Hyphaene compressa), a Semi-Domesticated Palm in the Arid and Semi-Arid Regions of Kenya
(Hindawi, 2020-12-29)Hyphaene compressa is an economically important palm in Africa. Despite its significant role in the livelihoods of rural communities, the diversity of doum palm is poorly documented and studied. In addition, it has no ... -
Photolabelling of Prostaglandin E2 receptor in cardiac sarcolemmnal vesicles
(1990)A [3H]azidophenacyl ester of PGE2 ([3H]azido-PGE2) was synthesized and used to photoaffinity label the protein component of the high affinity PGE2 binding site in cardiac sarcolemma membrane. Photolysis of the isolated ... -
Phylogenetic and morphological diversity of culturable cyanobacteria from Lake Magadi in Kenya
(2019-10)Lake Magadi is an alkaline saline Lake in Kenya, which lies on the Great Eastern Rift valley. Although the lake is characterized by extremes of salt, pH and temperature, it supports diverse groups of cyanobacteria. In ... -
Phylogenetic relationship and divergence among planktonic strains of Arthrospira (Oscillatoriales, Cyanobacteria) of African, Asian and American origin deduced by 16S–23S ITS and phycocyanin operon sequences
(2010-07)Arthrospira comprises multicellular, cylindrical, usually screwlike coiled trichomes and is cultivated commercially. In this study, 33 new strains of Arthrospira isolated from plankton samples collected in Mexico, East ... -
Physical and Chemical Characteristics of Five Hot Springs in Eritrea
(IISTE, 2017-07)Eritrea has a number of hot springs whose physicochemical characteristics are not documented. This study examined the thermal and chemical features of five hot springs located in the eastern escarpment of Eritrea. Field data ... -
Physico-Chemical and Microbial Quality of Greywater from Various Households in Homa Bay Town
(2011)In recent years concerns over dwindling reserves of ground water and overloaded or costly sewage treatment plants has generated much interest in the reuse or recycling of greywater. Re-use of greywater offers several ... -
The Physico-chemical Conditions of Turkwel Gorge Reservoir, a New Man Made Lake in Northern Kenya
(1999)Variations in some physical, chemical, and nutrient conditions were investigated at Turkwel Gorge Reservoir and its inflowing river, Suam between 1994 and 1995. Seasonal changes in inflow volume had the greatest impact ... -
