(Taylor and Francis, 2021)A new oleanane type triterpene characterized as 3a, 24-diacetoxy12-oleanene (1) together with known compounds 2-10, were isolated from Annona mucosa leaf extracts. Their structural elucidation was accomplished using ... -
Effect of nitrogen application on the expression of drought-induced root plasticity of upland NERICA rice
(Taylor & Francis, 2019)This study evaluated the effect of three N fertilization levels 60 (low), 120 (medium), and 180 (high) kg N ha−1 and soil moisture content gradients created by a line-source sprinkler on the expression of plasticity in ... -
Interactive influence of rainfall manipulation and livestock grazing on species diversity of the herbaceous layer community in a humid savannah in Kenya
(Elsevier, 2019)Changes in rainfall regime and grazing pressure affect vegetation composition and diversity with ecological implications for savannahs. The savannah in East Africa has experienced increased livestock grazing and rainfall ... -
Predictors of Ocular Surface Squamous Neoplasia and Conjunctival Squamous Cell Carcinoma among Ugandan Patients: A Hospital-based Study
(Wolters Kluwer--Medknow Publications, 2018)AIM: The aim of the study was to assess the predictors of ocular surface squamous neoplasia (OSSN) and conjunctival squamous cell carcinoma (SCC) among Ugandan patients. MATERIALS AND METHODS: Patients presenting for ... -
The management of microbial keratitis within Uganda’s primary health system: a situational analysis
(The Wellcome Trust, 2019)Background: Microbial keratitis (MK) frequently leads to sight-loss, especially when the infection is severe and/or appropriate treatment is delayed. The primary health system as an entry point plays a central role in ... -
Traditional eye medicine use in microbial keratitis in Uganda: a mixed methods study
(The Wellcome Trust, 2019)Background: Traditional eye medicine (TEM) is frequently used to treat microbial keratitis (MK) in many parts of Africa. Few reports have suggested that this is associated with a worse outcome. We undertook this large ... -
Delay Along the Care Seeking Journey of Patients with Microbial Keratitis in Uganda
(Taylor & Francis, 2019)PURPOSE To describe the care seeking journey and causes of delay among patients with Microbial Keratitis in Uganda. METHODS A prospective cohort of patients presenting with microbial keratitis at the two main eye units ... -
The management of microbial keratitis within Uganda’s primary health system: a situational analysis
(Wellcome Open Research, 2019)Background: Microbial keratitis (MK) frequently leads to sight-loss, especially when the infection is severe and/or appropriate treatment is delayed. The primary health system as an entry point plays a central role ... -
The impact of microbial keratitis on quality of life in Uganda
(BMJ Specialist Journals, 2019)Background Microbial keratitis (MK) is a frequent cause of sight loss in sub-Saharan Africa. However, no studies have formally measured its impact on quality of life (QoL) in this context. Methods As part of a nested ... -
Risk Factors of Microbial Keratitis in Uganda: A Case Control Study
(Taylor & Francis, 2020)Purpose: Microbial keratitis (MK), is a frequent cause of sight loss worldwide, particularly in low and middle-income countries. This study aimed to investigate the risk factors of MK in Uganda. Methods: Using a nested ... -
Epidemiology of Microbial Keratitis in Uganda: A Cohort Study
