ABSTRACT African leafy vegetables are a good source of vitamin A, vitamin C, and foliate among others. They are also a complementing source of other vitamins such as thiamine, niacin and riboflavin, plus some dietary minerals including calcium, iron, potassium, zinc, copper and manganese. Decline in crop yields is mainly caused by loss of soil fertility. Phosphorus (P) is one of the critical elements that limit vegetable production. The situation is aggravated in smallholder agriculture where...
The introduction of combined therapy has been an important breakthrough in the treatment of HIV infection, however for proper eradication, HIV pathogenesis has to be understood. Despite treatment with combinatorial therapies, a functional cure approach would be very effective in suppressing viraemic load in the host to such low levels that the immune system would be able to control the infection without the need for antiretroviral therapy, neither inflicting harm upon the host nor transmissio...
ABSTRACT Ganoderma polypore species are hard, leathery poroid mushrooms that lack the distinct stipe. They are a unique group of fungi usually ignored by most fungi enthusiasts because of their typical inedibility, unfamiliar habitat and general opacity. In addition to their traditional use, contemporary research has suggested many applications for cancer treatment and boosting of the immune system. Due to increase in bacterial resistance to existing antibiotics infectious diseases have ...
ABSTRACT Malaria is a health problem and drug resistance to antimalarial poses a great challenge to its treatment and control. Having a rapid activity against malaria parasites, artemisinins are the front line antimalarials. However, already there are reports on reduced response to artemisinins. Thus it’s important to monitor resistance in malaria risky areas. Merozoite surface protein (MSP) 1 and 2 genotyping has shown difference between isolates from primary and recurrent infections ...
ABSTRACT Management of parasitic disease continues to be a burden and a major public health problem the world over today. Malaria is most lethal of the parasitic vector-borne diseases due to drug and vector resistance to the available chemotherapeutics and vector management strategies, respectively. Bacterial and fungal infections are opportunistic to persons with compromised immunity yet the available drugs are associated with occasional treatment failures while antibiotic resistance is grow...
Food poisoning syndrome results from ingestion of water and wild variety of food contaminated with pathogenic organisms (bacteria) and their toxins. Food poisoning must be suspected when an acute illness with gastrointestinal or neurological manifestation affect two or more persons or animals who have share a meal during the previous 24 to 72 hours. The term generally used encompasses both food related infection and food related intoxication. Food borne illness (FBI) often called food ...
ABSTRACT The process of lifting items like motor vehicles and farm tractors for the purpose of changing tyres and other maintenance activities usually involves extensive manual effort and high risk of injuries. In other to reduce the manual effort and the risk of injuries, a remote controlled jack is developed and tested. The equipment consists of a 5-tonne capacity hydraulic jack, and a drive and control system which comprises a 12 volts, 312 Watts d c electric motor, a sliding crank mech...
ABSTRACT The role of examination to any nation is to determine whether students have achieved the learning objectives. The examinations were administered at the end of the education (learning) system or periodically before the end of a system. This gave rise to the use of mock just before the KCSE examination is administered. The purpose of this study was therefore to investigate the role played by mock examination result in predicting students’ performance in the national examination in se...
ABSTRACT Biological control of Ceratocystis paradoxa using Trichoderma spp. were conducted on oil palm spouted seeds. Eighteen spp. of fungi belonging to ten genera were identified as fungi associated with diseased sprouted seeds. Out of these genera, Aspergillus spp. occurred most frequently and in relative abundance at 25.9%, Trichoderma spp. (23.4%), Ceratocystis paradoxa (11.1%), Fusarium spp (9.9%), Penicillium spp. (8.7%), Rhizopus sp. (7.4%) and Curvularia sp. (4.9%) respectively. Pest...
ABSTRACT The present invention relates to an improved control system for starting a three phase induction motor comprises improved power contactors configured to have a pair of three pole delta and main contactors, and a single pole star contactor for supplying AC power to star position and delta position, a timer for controlling AC power supply switching operation for star position and delta position and for adjusting a time delay of switching over from star connection to delta connectio...
ABSTRACT Data from HD-1 well, offshore Tano Basin was subjected to optical and organic geochemical analysis to reveal the palynostratigraphy, palaeoenvironments and hydrocarbon potential of the said well. Organic geochemical studies of Total Organic Carbon and Rock-Eval pyrolysis analysis as well as the microscopic investigation of the 44 slides of ditch cuttings from a depth of 3370ft – 7290ft shows four (4) types of Palynofacies associations in the HD-1 well based on the sedimentary organ...
Hepatitis E is a human disease mainly characterized by acute liver illness, which is caused by infection with the hepatitis E virus (HEV). Large hepatitis E outbreaks have been described in developing countries; however, the disease is also increasingly recognized in industrialized countries. Mortality rates up to 25% have been described for pregnant women during outbreaks in developing countries. In addition, chronic disease courses could be observed in immunocompromised transplant patients....
ABSTRACT There has been an increase in the occurrence of antibiotic resistance among Salmonella enterica, one of the commonest causative agents of Salmonella infections. Fluoroquinolones and third generation cephalosporins are usually the drugs of choice in the management of Salmonella infections. Previous reports have indicated common occurrence of multi-drug resistance (MDR) including resistance to β-lactams and fluoroquinolones among clinical Gram-negative organisms. However, there is pa...
ABSTRACT Urinary tract infections (UTI) are bacterial infections encountered in the hospital and community and is preventable. It is among bacterial infection encountered with increasing antibiotic resistance to uropathogens, although there is availability of antibiotics. Despite the wide spread of antibiotics, it remains the common bacterial infections. Antibiotic susceptibility testing therefore provides information that allows clinicians to select the most appropriate antimicrobial drugs. ...
Abstract: Pectinase is a heterogeneous group of enzyme which hydrolyzes pectin. Fungi and actinomycetes have ability to produce a large amount of industrial enzymes. Therefore the present study was undertaken production of pectinolytic enzymes from barley (Hordeum vulgare Von. Bothmer) and wheat (Triticum turgidum L.Von) locally called (Garbu or Qamadi) hulls. Wheat and Barley Hulls samples were collected from homes. Isolation of the fungal species was done on czapek-dox-agar media. Fungal i...
