Identification and Characterization of Variant Surface Glycoprotein (VSG) Genes with diagnostic potential for Trypanosoma brucei rhodesiense.

ABSTRACT Human African Trypanosomiasis (HAT) is present in 36 sub-Saharan African countries. The disease is easier to treat in early stage than late stage when treatment with melarsoprol is responsible for significant fatality. Therefore there is need to develop a diagnostic test for early detection before progression of the disease into the late stage. Currently available tests have poor sensitivity. Thus highly sensitive methods are needed for the detection of the parasite in human blood. T...

A Preliminary Study On The Effects Of Khat (Catha Edulis) On Liver And Kidney Of Mice

ABSTRACT Chewing of Khat, which typically consists of the young leaves and shoots of the Catha edulis plant for its stimulant effects, is rampart in East, Central and Southern Africa, UAE, Saudi Arabia, Yemen, Oman, Iraq, Iran Afghanistan, Pakistan and Bangladesh. Khat contains more than 40 alkaloids, glycosides, tannins, amino acids, vitamins and minerals. Most of the effects of chewing Khat are thought to come from two phenylalkylanines-cathinone and cathine which are structurally related ...

Prevalence And Association Of Conventional And Novel Risk Factors For Coronary Heart Disease In Langata Constituency, Nairobi, Kenya

ABSTRACT  There has been considerable progress in the understanding of conventional risk factors for cardiovascular disease such as cigarette smoking, hypertension, hyperlipideamia and diabetes. However they do not fully account for cardiovascular disease-associated complications. As a result, novel risk factors such as C-reactive protein (CRP) and homocysteine have come under investigation. The aim of this study was to determine the prevalence and interrelation of conventional and novel ris...

Evaluation Of Quantity And Quality Of Biodiesel Produced From Jatropha Curcas In Different Parts Of Kenya

ABSTRACT Biodiesel as an alternative fuel for diesel engines is becoming increasingly important due to diminishing petroleum reserves and the environmental consequences of exhaust gases from petroleum-fuelled engines. The availability and sustainability of sufficient supplies of less expensive feedstock will be a crucial determinant delivering a competitive biodiesel to the commercial filling stations. Fortunately, inedible vegetable oils, mostly produced by seed-bearing trees and shrubs can...

Iron Deficiency Anaemia And Its Association With Malaria Infection In Children In Siaya County In Western Kenya

ABSTRACT Iron deficiency anaemia contributes to 50% cases of anaemia and it remains a concern in the public health sector in sub-Saharan Africa and children under five years are at risk. It is associated with poor cognitive development and affects growth of preschool children. The interventions in most of sub-Saharan Africa focus on the improvement of hemoglobin (Hb) levels but it is not clear if Hb and iron levels relate in areas where there are multi-factorial causes of anaemia. The preval...

Anti-Obesity, Cognitive Enhancing, Neurobehavioral, Antioxidant Effects And Phytochemical Profile Of Dichloromethane Leaf Extract Of Gnidia Glauca (Fresen)

ABSTRACT Obesity is a chronic metabolic disorder characterized by increased adipose tissue mass due to positive energy balance. The epidemic of obesity is currently on the rise probably due to increasingly sedentary lifestyles combined with easy availability of palatable, high-fat foods. It presents modifiable risk factor for cognitive impairements, anxiety and motor deficits. Globally, its prevalence has shown a startling increase in all age groups and have been associated with increased mo...

Antidiabetic Activity And Safety Of Piper Capense, Berberis Holstii, Sonchus Asper, Vernonia Lasiopus And Galinsoga Parviflora In Alloxan-Induced Diabetic Albino Mice

ABSTRACT In Kenya, diabetes mellitus is of health concern to the public, because it causes substantial morbidity, mortality, and long-term complications. Synthetic drugs used in the management of diabetes are unavailable, have numerous side effects and are expensive. Many plants such as Piper capense, Berberis holstii, Sonchus asper, Vernonia lasiopus and Galinsoga parviflora used traditionally to manage many diseases including diabetes mellitus but their efficacy and safety after long-term ...

Antipyretic And Anti-Inflammatory Activities Of Dichloromethane-Methanolic Leaf And Stem Bark Extracts Of Ximenia Americana In Rats And Mice Models

ABSTRACT Extremely high body temperatures lead to destruction of body cells while excessive inflammation cause damage to body tissues and organs, therefore, the need to treat fever and inflammation. Conventional treatment is associated with many side effects hence the need for a treatment option that is more tolerable. Herbal medicines such as X. americana are arguably associated with minimal side effects. Ximenia americana is widely used as folk medicine in Africa to treat various disorders ...

In Vitro Antioxidant Effects Of Dichloromethane –Methanol Leaf Blend Extracts Of Clutia Abyssinica And Maytenus Obscura.

ABSTRACT Oxidative stress is a state of imbalance between free radicals and antioxidants in the body. It is the main cause of several disease conditions such as diabetes, different types of cancers, cardiovascular diseases, inflammation and aging. Oxidative stress is managed by use of antioxidants which can be obtained in the diet or given as supplements. Antioxidants are substances with the ability to prevent oxidation of other molecules in the body by free radicals. Antioxidants react with ...

Phenotypic and Molecular Characterization of Hard Ticks (Acari: Ixodidae) Sampled from Wild Herbivores from Lake Nakuru and Tsavo National Parks in Kenya

ABSTRACT Hard ticks (Acari: Ixodidae) are ubiquitous blood feeding ectoparasites that infest humans and animals and are vectors of pathogenic micro-organism of rickettsial, bacterial, viral and protozoal origin that cause severe infectious diseases in humans and livestock. Wild herbivores support a large population of these vectors and accurate and quick identification of ticks is therefore important. Morphological identification based on phenotypic criteria has been the main approach but the...

ABSTRACT The protective and antioxidant properties of Aqueous Anti-ulcer Drug (AQAUD) against Aspirin-induced gastric ulcers in albino rats were investigated. In this study, thirty male albino rats were divided into five groups. Rats in group I served as normal control and received food and water. Animals in group II received food and water in addition to aspirin 400mg/kg.b.wt orally on the 14th day. Rats in groups III, IV and V received “AQAUD” 250mg/kg.b.wt, 500mg/kg.b.wt and Omeprazol...

Occurrence, antibiotics and disinfectants resistance of extended spectrum β-lactamases producing e. Coli and k. Pneumonia and the genes encoding for the resistance in kenya

ABSTRACT Extended-spectrum beta-lactamases (ESBLs) are enzymes that mediate resistance to βlactam antibiotics by opening the beta-lactam ring of penicillin derived antibiotics, and another family of antibiotics, rendering them inactive against the bacteria they are intended to kill. The ESBLs were first identified in 1939 and since then, they have proliferated worldwide and have been found in a number of different bacteria, such as Klebsiella pneumonia, and Escherichia coli among others. Th...

Production Of Hybrid Rice Using Environment Sensitive Genic Male Sterile (Egms) And Basmati Rice Lines

ABSTRACT Rice is the third major food crop in Kenya and, its production is estimated at 129,000 tons which is below the annual national demand of 548,000 tons. Kenya rice yields per hectare are very low compared to major producers like China. Basmati (B) varieties, B370 and B217, are preferred by most rice consumers and are cultivated as a cash crop by 98.8% of Mwea rice farmers. This is because they have strong aroma. Due to the demand, basmati rice command high premium prices locally and in...
