Phylogenetic Distribution of Species Complex Populations in Potato in Kenya.

is a pathogen causing bacterial wilt disease of potato, resulting in 70% potato production losses in Kenya. A study was conducted to determine the diversity of species complex strains within the main potato-growing regions of Kenya. Potato tubers were collected in different potato-growing regions of Kenya from visibly wilted potato plants as well as samples of tomato, irrigation water, and cultures for pathogen isolation.

A review of varietal change in roots, tubers and bananas: consumer preferences and other drivers of adoption and implications for breeding.

This review of the literature on varietal change in sub-Saharan Africa looks in detail at adoption of new varieties of bananas in Uganda, cassava in Nigeria, potato in Kenya, sweetpotato in Uganda and yams in Côte d'Ivoire. The review explored three hypotheses about drivers of varietal change. There was a strong confirmation for the hypothesis that insufficient priority given to consumer-preferred traits by breeding programmes contributes to the limited uptake of modern varieties (MVs) and low varietal turnover.

Expanded Demographic Norms for Version 3 of the Alzheimer Disease Centers' Neuropsychological Test Battery in the Uniform Data Set.

Background: Norms for the Uniform Data Set Version 3 Neuropsychological Battery are available for cognitively normal individuals based on age, education, and sex; however, these norms do not include race. We provide expanded norms for African Americans and whites.

Methods: Data from 32 Alzheimer's Disease Centers (ADCs) and ADC affiliated cohorts with global Clinical Dementia Rating Scale (CDR) Dementia Staging Instrument scores of 0 were included.

The Effect of the "" on Psychological Outcomes, Burden, and Mastery in African American Caregivers of Persons Living With Dementia.

The "," a cultural adaptation of a psychoeducation intervention the "" for African American caregivers of persons living with dementia (PLwD), aims to develop caregivers' skills and improve the quality of the lives of both the PLwD and their caregivers. The goal of this study was to determine the effectiveness of the on depressive symptoms, anxiety, burden, and mastery in African American caregivers ( = 142). A three-arm randomized control trial ( + exercise, and attention control) was conducted over a period of 6 months.

Molecular Epidemiology of Species Complex Strains Causing Bacterial Wilt of Potato in Uganda.

Bacterial wilt (BW) caused by the species complex (RSSC) is a serious threat to potato production in Uganda. However, little is known about the extent of the disease and the type of the pathogen strains involved. A nationwide survey was conducted to study BW prevalence and incidence in potato, and potato tuber and stem samples of potential alternative hosts were collected for pathogen isolation.

Comparative Evaluation of LAMP, qPCR, Conventional PCR, and ELISA to Detect in Kenyan Potato Fields.

Bacterial wilt caused by is considered among the most damaging diseases of potato in Sub-Saharan Africa and the most significant biotic constraint of potato production alongside late blight. Unlike late blight, which can be managed by chemical means, can only be managed through cultural methods and clean seed. Laboratory testing to certify seed before planting is required to confirm the absence of the pathogen in Kenya.
