Abstract:

BACKGROUND: Alzheimer's disease (AD) is a complex, multifactorial neurological disorder characterized by an insidious onset with progressive symptoms of memory impairment, language deficit, behavioural problems including agitation, mood disturbances and poor judgment. AD involves multiple pathogenetic factors such as A~ production and aggregation, oxidative stress, tau protein aggregation, metal ions (e.g. Cu2+, Zn2+, Fe2+) and reduced levels of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes. All these factors play important roles in neurodegeneration associated with AD.

Abstract:

This thesis represents studies on aspects of the defenses against insect herbivores in species of the plant family Meliaceae, particularly with regard to phytochemicals. Methanolic extracts of foliage from thirty species in twenty-two genera were bioassayed for toxicity and growth inhibitory activity against the variegated cutworm, Peridroma sauciaf and for feeding inhibition against the migratory grasshopper, Melanoplus sanguinipes. All but three species were inhibitory to P. saucia, members of the tribe Melieae being most inhibitory. Members of the subfamily Melioideae were more active than

Abstract:

>Magister Scientiae - MSc<br>Nanotechnology has emerged as a promising field in the quest to address health conditions. Green nanotechnology is a fairly new branch of nanotechnology, which aims to produce and utilize nanomaterials in a way that is safe for living organisms and their environment. Plant extracts are increasingly used in the green synthesis of gold nanoparticles (AuNPs), which involves the reduction of sodium tetrachloroaurate (III) dehydrate by phytochemicals present in the plant extract. It is probable that the green synthesised AuNPs are more biocompatible than chemically synt

Abstract:

Thesis MTech (Food Technology))--Cape Peninsula University of Technology, 2017.<br>Bambara groundnut (Vigna subterranea) an indigenous legume cultivated in Sub-Saharan Africa has been proclaimed to have medicinal properties from communities and in rural areas. However, there is not enough scientific information to validate these claims. Therefore, this study aimed to identify possible medicinal properties of Bambara groundnut (BGN), by analysing the phytochemical and antimicrobial properties of BGN seed and product extracts from Mpumalanga province within South Africa. The BGN extracts (70% me

Abstract:

Thesis (MTech (Horticulture))--Cape Peninsula University of Technology, 2018.<br>Ticks and tick-borne diseases are important limiting factors to the attainment of sustainable animal and human health, affecting livelihood of resource poor farming communities in developing countries. Rhipicephalus appendiculatus and Amblyomma variegatum (Ixodidae) are among the most troubling tick species in Africa. While ticks can be controlled by applying chemical acaricides, these chemicals are quite expensive, especially, for small-scale famers in developing countries. Hence, the quest for alternative tick c

Abstract:

O gênero Salmonella constitui um problema para a saúde animal e humana. Com a finalidade de evitar a ocorrência da transmissão deste microrganismo e a interrupção da doença provocada por eles, deve-se utilizar desinfetantes e antibióticos. A exposição continuada a estes agentes pode resultar no surgimento de resistência microbiana. Tendo em vista este fenômeno, a pesquisa por novos agentes antimicrobianos a partir de extratos vegetais se faz necessária, pois existe a possibilidade de se encontrar substâncias eficazes contra a resistência de micro-organismos já disseminados no ambiente.

Abstract:

In Africa, the importance of medicinal plants in folklore medicine and their contribution to primary healthcare is well recognized. Across the continent, local herbal mixtures still provide the only therapeutic option for about 80% of the population. The vast floral diversity and the intrinsic ethnobotanical knowledge has been the backbone of localized traditional herbal medical practices. In Africa, an estimated 5400 of the 60000 described plant taxa possess over 16300 therapeutic uses. Similarly, with a therapeutic flora comprising of approximately 650 species, herbal medical practitioners i
