Spatial distribution and consumption patterns of Woodfuel in Sabatia Division, Kenya
(Journal of technology and socio-economic development, 2011)In the second phase of the Smallholder Dairy Research and Development Project (SDP), as well as continuing work in central Kenya, attention will be given to Western Kenya where lessons learnt from the Central and Coast ... -
Reorganization of cytoskeleton during surfactant secretion in lung type II cells: a role of annexin II
(Elsevier, 2003)The secretion of lung surfactant requires the movement of lamellar bodies to the plasma membrane through cytoskeletal barrier at the cell cortex. We hypothesized that the cortical cytoskeleton undergoes a transient ... -
Syntaxin 2 and SNAP-23 are required for regulated surfactant secretion
(2014)The secretion of lung surfactant in alveolar type II cells is a complex process involving the fusion of lamellar bodies with the plasma membrane. This process is somewhat different from the exocytosis of hormones and ... -
Modulation of eotaxin-3 (CCL26) in alveolar type II epithelial cells
(2007)Airway epithelial inflammation associated with emphysema, chronic bronchitis, chronic obstructive pulmonary disease (COPD) and asthma is regulated in part by alveolar type II cell chemokine signaling. Data suggest that ... -
Post-transcriptional silencing of CCR3 downregulates IL-4 stimulated release of eotaxin-3 (CCL26) and other CCR3 ligands in alveolar type II cells
(2008)Trafficking and inflammation in airway diseases are, in part, modulated by members of the CC chemokine family, eotaxin-1 (CCL11), eotaxin-2 (CCL24), and eotaxin-3 (CCL26), which transduce signals through their CCR3 receptor. ... -
Cytokine-stimulated human lung alveolar epithelial cells release eotaxin-2 (CCL24) and eotaxin-3 (CCL26)
(Mary Ann Liebert, Inc, 2005)Asthma is a complex inflammatory disease characterized by a prolonged underlying airway inflammation resulting from cytokine-orchestrated signaling between many types of cells, including airway epithelial cells. Trafficking, ... -
CCL26-targeted siRNA treatment of alveolar type II cells decreases expression of CCR3-binding chemokines and reduces eosinophil migration: implications in asthma therapy
(2009)The underlying infl ammation present in chronic airway diseases is orchestrated by increased expression of CC chemokines that selectively recruit leukocyte populations into the pulmonary system. Human CCL26 signals through ... -
Characterization of -soluble n-ethylmaleimide–sensitive fusion attachment protein in alveolar type ii cells implications in lung surfactant secretion
(2002)N-ethylmaleimide–sensitive fusion protein (NSF) and soluble NSF attachment protein (α-SNAP) are thought to be soluble factors that transiently bind and disassemble SNAP receptor complex during exocytosis in neuronal and ... -
Autoregulation of ccl26 synthesis and secretion in a549 cells: a possible mechanism by which alveolar epithelial cells modulate airway inflammation
(2005)Abonyo, B. O., M. S. Alexander, and A. S. Heiman. Autoregulation of CCL26 synthesis and secretion in A549 cells: a possible mechanism by which alveolar epithelial cells modulate airway inflammation. Am J Physiol Lung Cell ... -
Effective group learning: A case of perspectives from Kenyan high school students
(Eldoret Polytechnic, Kenya, 2013)In this study we examined whether and how youth learned life skills through their involvement on a high school soccer team. We collected data from fieldwork and interviews with 12 male student-athletes and the head ... -

Kenyan students’ resonance with contextualized science: Critical reflections on traditional science curriculum and instruction
(Eldoret Polytechnic, 2013)Despite the centrality of the informal manufacturing sector (Jua Kali) to the Kenyan society and its richness in scientific phenomena, there is no strong link between activities in the Jua Kali and school science. And, ... -
Projected rainfall and temperature changes over Bungoma county in western Kenya by the year 2050 based precis modeling system
(Dept. of Geography, Bahir Dar university, 2016)This study investigated projected changes in rainfall and temperature over Bungoma County by the year 2050 based on the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emission Scenarios (SRES) A1B and ... -
Contextualized science teaching and student performance: The case of a kenyan girls science class
(Instituto de relaciones internacionales daza de valdes, 2017)This paper is about a case study that investigated the impact of contextualized science teaching and learning onperformance of a Form three (Grade 11) class in one of Kenya’s girls high schools. The class experienced nine ... -
Health implications of heavy metals in soil, scalp hair and selected food crops within Eldoret Municipality, Kenya
(Journal of environmental science, toxicology and food technology, 2013)Heavy metals were analyzed in soils, food crops and male scalp hair samples collected from two age group subjects; adults (18 - 45 years) and old age (46 - 55 years) males from polluted and relatively less polluted areas ... -
Student learning impact on science teachers’ teaching: The case of a form 3 science case in Kenya .
(201)This paper reports on the study that investigated the following question: How do Kenyan science teachers perceive the impact of students’ contextualized science learning on their pedagogy, roles and Views about previously ... -
Heavy metal distribution in soils of some urban and peri-urban horticultural farms in Botswana
(RUFORUM, 2014-07)Despite the fact that there is high usage of agrochemicals and use of urban waste water for irrigation, the concentration of potentially toxic metals in urban and peri-urban agriculture (UPA) farms has not been widely ... -
The use of phytochemical composition of fifty (50) selected plants found in the university botanic garden, Maseno, Kenya to show
(2015-08-02)Qualitative phytochemical analysis of 50 plants, five each from 10 selected families is presented. The ten plant families were selected based on their high plant frequency of occurrence within the botanic garden. The powdered ... -
Effects of fresh leaf materials of sesbania sesban (l.) merrill on the growth and photosynthetic pigments of nightshade (solanum nigrum l. var. popolo)
(INNSPUB, 2014-05-15)Solanum nigrum L. is one of the African leafy vegetable consumed in Kenya. High cost of inorganic fertilizers has made it inaccessible by smallholder farmers leading to low yields. A study was conducted at Maseno ... -
