A prospective study of endothelial activation biomarkers, including plasma angiopoietin-1 and angiopoietin-2, in Kenyan women initiating antiretroviral therapy
(BioMed Central Ltd., 2013)Background HIV-1-related inflammation is associated with increased levels of biomarkers of vascular adhesion and endothelial activation, and may increase production of the inflammatory protein angiopoietin-2 (ANG-2), an ... -
Sickle cell trait (HbAS) is associated with increased expression of erythrocyte complement regulatory proteins CR1 and CD55 levels in children
(International Journal of TROPICAL DISEASE & Health, 2013)Aims: Erythrocyte complement regulatory proteins, complement receptor 1 (CR1) and decay accelerating factor (CD55) protect red blood cells (RBCs) from complement mediated damage by controlling complement activation cascade ... -
Nutrient composition of four species of winged termites consumed in western Kenya
(Elsevier, 2013)The objective of this study was to gain knowledge on the nutrient composition of Macrotermes subhylanus, Pseudacanthotermes militaris, Macrotermes bellicosus and Pseudacanthotermes spiniger termite species consumed in ... -
The Plasmodium falciparum antigen MB2 induces interferon-γ and interleukin-10 responses in adults in malaria endemic areas of Western Kenya
(PMC, 2013)Background: MB2 is a novel Plasmodium falciparum antigen of unknown function expressed in pre-erythrocytic and blood stages of infection in the human host. Interferon-gamma (IFN-γ) and interleukin (IL)-10 responses to ... -
Spatial distribution and habitat characterization of schistosomiasis host snails in lake and land habitats of western Kenya
(John Wiley & Sons, Inc, 2013)Intermediate host snails of schistosomiasis were surveyed in this study to determine their abundance and distribution in the lake and land aquatic habitats of Lake Victoria basin of Kenya. Several sites were sampled at ... -
Molecular detection of Rickettsia felis and Candidatus Rickettsia Asemboensis in fleas from human habitats, Asembo, Kenya
(Mary Ann Liebert, Inc., 2013)The flea-borne rickettsioses murine typhus (Rickettsia typhi) and flea-borne spotted fever (FBSF) (Rickettsia felis) are febrile diseases distributed among humans worldwide. Murine typhus has been known to be endemic to ... -
Coxiella burnetii in humans, domestic ruminants, and ticks in rural Western Kenya
(The American Society of Tropical Medicine and Hygiene, 2013)We conducted serological surveys for Coxiella burnetii in archived sera from patients that visited a rural clinic in western Kenya from 2007 to 2008 and in cattle, sheep, and goats from the same area in 2009. We also ... -
Changes in b cell populations and Merozoite surface protein-1-specific memory b cell responses after prolonged absence of detectable p. falciparum infection
(PLOS, 2013-05)Clinical immunity to malaria declines in the absence of repeated parasite exposure. However, little is known about how B cell populations and antigen-specific memory B cells change in the absence of P. falciparum infection. ... -
Endothelial activation biomarkers increase after hiv-1 acquisition: plasma vcam-1 predicts disease progression
(PMC, 2013-07-17)Objective—We aimed to determine whether endothelial activation biomarkers increase after HIV-1 acquisition, and whether biomarker levels measured in chronic infection would predict disease progression and death in HIV-1 ... -
Patterns and trends of malaria morbidity in Western highlands of Kenya
(International Journal of Education and Research, 2013-12)A study of patterns and trends of malaria morbidity was conducted in Kericho district in Kenya western highlands prone to occurrences of malaria epidemics. Kericho district supports small scale and large scale tea farming, ... -
Urinary cytokines in Schistosoma haematobium-infected schoolchildren from Tana Delta District of Kenya
(BioMed Central Ltd., 2014)Background: Pathological changes due to infection with Schistosoma haematobium include cytokine-mediated urinary tract inflammation. The involved cytokines may be excreted in urine and their presence in urine may therefore ... -
Participation of fishing communities in neglected tropical disease/HIV co-infection Cohort Studies in Western Kenya
(2014)Background: Fishing communities on the shores of Lake Victoria are at high risk of schistosome infections, and at the same time, also considered at high risk of HIV infection due to factors associated with lifestyle or ... -
Presence and distribution of mosquito larvae predators and factors influencing their abundance along the Mara River, Kenya and Tanzania
(spring open.com, 2014)Among all the malaria controlling measures, biological control of mosquito larvae may be the cheapest and easiest to implement. This study investigated baseline predation of immature mosquitoes by macroinvertebrate predators ... -
Evolution of the primate trypanolytic factor APOL1
(PNAS, 2014-04-08)ApolipoproteinL1 (APOL1) protects humans and some primates against several African trypanosomes. APOL1 genetic variants strongly associated with kidney disease in African Americans have additional trypanolytic activity ... -
Norm Inequalities for positive elementary operators and entanglement of states
(Journal of Global Research in Mathematical Archives, 2014-05-05)We present norm inequalities for positive elementary operators via Cauchy-Schwarz inequality and Minkowskis inequality techniques. Norm inequalities are presented in Euclidean algebras linked to Minkowski’s light cones. ... -
Projective Norms and Convergence of Norm-Attainable Operators
(Journal of Global Research in Mathematical Archives, 2014-05-05)Let H be an infinite dimensional complex Hilbert space and B(H) the algebra of all bounded linear operators on H. We establish norm-attainability of operators via projective tensor norm. Moreover, we give results on the ... -
Decline in childhood iron deficiency after interruption of malaria transmission in highland Kenya1–3
(AJCN, 2014-07-30)Background: Achieving optimal iron status in children in malariaendemic areas may increase the risk of malaria. Malaria itself may contribute to iron deficiency, but the impact of an interruption in malaria transmission ... -
