Protein polymorphism in two populations of the brown ear tick, Rhipicephalus appendiculatus Neumann (Acari: Ixodidae)
(2000)Two-dimensional gel electrophoresis was used to compare the protein profiles of two geographically isolated populations of the tick Rhipicephalus appendiculatus Neumann (Acari: Ixodidae) in Kenya. Most of the protein spots ... -
Protein-RNA interface residue prediction using machine learning: an assessment of the state of the art
(2012)RNA molecules play diverse functional and structural roles in cells. They function as messengers for transferring genetic information from DNA to proteins, as the primary genetic material in many viruses, as catalysts ... -

Proximity Density Assessment and Characterization of Water and Sanitation Facilities in the Informal Settlements of Kisumu City: Implications for Public Health Planning
(University of Nairobi, 2020)Access to water and sanitation remain a challenge in many developing countries, especially in pro-poor urban informal settlements where socioeconomic livelihoods are generally low. The aim of this study was to characterise ... -
Psoriasin (S100A7) Expression Is Associated with Poor Outcome in Estrogen Receptor-negative Invasive Breast Cancer
(College of Physical and Biological Sciences, 2003)Purpose: Psoriasin (S100A7) is highly expressed in preinvasive ductal carcinoma in situ of the breast and persistent expression occurs in some invasive carcinomas. This study explores the clinical significance of psoriasin ... -
Pterocarpans and isoflavones from the root bark of millettia micans and of millettia dura

Putnam-Fuglede Theorem For N-Power Normal And W-hyponormal Operators,
(University of Nairobi, 2014)Reducibility implies direct sum decompositions of Hilbert space operators and any pair of operators which satisfy the Putnam-Fuglede theorem is reducible. In this presentation, the familiar Putnam-Fuglede theorem is ... -
Putnam’s inequality for n-Power normal, n-Power quasinormal and w-hyponormal operators,
(University of Nairobi, 2014)Every reducible operator can be decomposed into normal and completely non-normal operators. Unfortunately, there are several non normal operators which are irreducible. However, every operator whose self-commutator is ... -
Pyrazole, isoxazoline and bypyrimidine derivatives from polygonum senegalense and psiadia punctulata flavonoids and their anti- microbial activities
(University of Nairobi, 2017)Currently, researchers have given special attention to the synthesis of hetero cyclic compounds with nitrogen and oxygen five in five or six membered ring systems. This is mainly due to their wide range of biological ... -
