Evaluation Of The Effectiveness Of Antimalarial Interventions During Pregnancy In Blantyre, Malawi

ABSTRACT Due to an increased risk of malaria during pregnancy, WHO recommends a strategic framework for malaria prevention and control during pregnancy in areas of stable transmission in Africa such as Malawi. One of the central policies is intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP). However, the emergence of SP resistance calls into question its effectiveness for IPTp. It has recently been demonstrated that 12 years after the withdrawal of chlor...

Evaluation Of Pre-Attachment And Post-Attachment Striga Hermonthica (Del.) Benth. Resistance In Pearl Millet (Pennisetum Glaucum (L.) )

ABSTRACT Striga species are parasitic weeds, one of the most devastating biological constraint threatening agriculture especially production of cereals in sub-Saharan Africa (SSA), causing approximately 30% to near crop failure, thus endangering the livelihood of more than 300 million poor smallholder famers. One way of combating Striga is having natural host resistance which is cost effective and efficient for tolerance to phytopathogenic damages. Such resistance can either be due to fai...

Bioprospecting For Hypoglycemic Activities And Safety Of Selected Traditionally Used Plants In The Management Of Diabetes Mellitus

ABSTRACT Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar levels that result from defects in insulin secretion, or action, or both. The disorder completely throws the metabolism of dietary carbohydrates, lipids and proteins into disarray. This condition in its fully developed form is characterized by high blood sugar level (hyperglycemia), glycosuria, increased protein breakdown, ketosis and acidosis. Diabetes is a chronic medical condition which can be con...

Effects Of Highly Active Antiretroviral Therapy On The Liver And Kidney Functions In Hiv Patients At Coast Province General Hospital, Kenya

ABSTRACT The emergence of highly active antiretroviral therapy (HAART) has led to dramatic improvements in prolonging survival of HIV-infected patients on treatment in resource-limited areas. However, the main drawback of HAART that long-term use has the potential to cause liver and kidney derangements that may be life-threatening. These important complications sometimes warrant switch or discontinuation of antiretroviral therapy. Information on the prevalence of the above complications in Ke...

Prophylactic Activity Of Hiv-Protease Inhibitors Against Malaria And Their Interaction With Antimalarial In Male Mice

ABSTRACT Malaria and HIV/AIDS have a wide geographical overlap in several tropical regions. This makes co-infection of the two diseases very common. Due to enhanced global coverage of antiretroviral drugs (ARVs), HIV/AIDS patients are under ARVs including protease inhibitors (PIs). Just like HIV, malaria parasite also depend on proteases in their life cycle. Therefore, PIs against HIV could offer some level of antimalarial activity by targeting the parasite proteases. This study sought to in...

Effects Of Dichloromethane-Methanolic Leaf Extracts Of Carissa Edulis (Forssk.)Vahl On Haematological And Serum Lipid Profiles In Normal Rat Models

ABSTRACT Assesment of hematological parameters and serum lipid profiles can be used to explain blood related functions of a plant extract. The blood can act as pathological reflector and also as an indicator of the physiological state of an animal. Hematological and lipid related disorders are increasingly on the rise while conventional management of these disorders are not easily accessible. This has prompted an increased use of medicinal plants which are readily available in the management ...

Physiological, Biochemical And Molecular Responses Of Tea (Camellia Sinensis L. O. Kuntze) Cultivars Grown In Kenya To Water Deficit

ABSTRACT Tea is one of the most popular non-alcoholic beverages worlwide, and a leading foreign exchange earner and source of livelihood to over three million people in Kenya. Tea growing areas in Kenya often experience drought periods which cause accumulated soil water deficits. Tea plants respond to water deficit through poorly understood physiological, cellular/biochemical and molecular processes. Development of tea cultivars adapted to waterdeficit stress greatly relies on an understandi...

Protective Role Of Antioxidant In Ameliorating African Trypanosomiasis - Induced Brain Degeneration In A Mouse Model

ABSTRACT Late stage Human African Trypanosomiasis (HAT) is manifested by brain degeneration following infection by Trypanasoma brucei rhodensiense and Trypanasoma brucei gambiense parasites. This stage can only be treated with melarsoprol (Mel B) which inadvertently induces Post Treatment Reactive Encephalopathy (PTRE) and a mortality of 5% among HAT infected patients. This is an unacceptable mortality for a modern human drug. Investigations were conducted to establish the protective role of...
