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
(University of Nairobi, 2016)From the CH2Cl2/CH3OH (1:1) extract of the root bark of Millettia micans, a new pterocarpan, (6aR,11aR)-7,8,9-trimethoxy-3-hydroxypterocarpan (1), named micanspterocarpan, was isolated. Similar investigation of the ... -

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 ... -

Quality Indicator framework for assessing DEel programs in Kenya: A Technological and Educational functional parameters approach
(University of Nairobi, 2016-04)The demand for university education has continued to grow and hence there has been a phenomenal expansion in enrolments that is not matching with the expansion of facilities. Several policy reports commissioned by the ... -
Quantification of carbon stocks in Mount Marsabit Forest Reserve, a sub-humid montane forest in northern Kenya under anthropogenic disturbance
(University of Nairobi, 2018)The quantification of carbon stocks is vital for decision making in forest management, carbon stock change assessment and scientific applications. We applied the land degradation surveillance framework (LDSF) method with ... -
Quantification of Theileria parva in Rhipicephalus appendiculatus (Acari: Ixodidae) confirms differences in infection between selected tick strains
(School of Biological Sciences, 2009)Theileria parva is the etiologic agent of East Coast fever, an economically important disease of cattle in sub-Saharan Africa. This protozoan parasite is biologically transmitted by Rhipicephalus appendiculatus (Neumann) ... -
Quantifying past and present connectivity illuminates a rapidly changing landscape for the African elephant.
(University of Nairobi.Reproductive Biology Unit, 2013-03)There is widespread concern about impacts of land-use change on connectivity among animal and plant populations, but those impacts are difficult to quantify. Moreover, lack of knowledge regarding ecosystems before fragmentation ... -
Quantifying the intensity of permethrin insecticide resistance in Anopheles mosquitoes in western Kenya.
(University of Nairobi, 2017)BACKGROUND: The development and spread of resistance among local vectors to the major classes of insecticides used in Long-Lasting Insecticidal Nets (LLINs) and Indoor Residual Spraying (IRS) poses a major challenge to ... -
Quantitative analysis of collagen and elastic fibers in the transversalis fascia in direct and indirect inguinal hernia
(University of Nairobi.Department of Mathematics, University of Nairobi, 2002)PURPOSE: Our previous studies demonstrated structural and quantitative age-related changes of the elastic fibers in transversalis fascia, which may play a role in inguinal hernia formation. To verify whether there were ... -
