AN ETHNOBOTANICAL AND Phyrochemical. STUDY OF THE MEDICINAL PLANTS OF MAKUENI DISTRICT, Kenyael1

ABSTRACTOf all the uses of African plants, the aspect of medical use has probably attracted the mostattention and has also been the most complex and varied. Nearly 70,000 species of higher plantshave been used for medical purposes world wide.Medicinal plants form the key component to traditional medicine which remains the major sourceof health care for over 70% of the Kenyan population. Over 90% of the population use medicinalplants at one time or another.The increasing need to develop drugs ...

Structural Elucidation Of Compounds From Lonchocarpus Eriocalyx

AbstractPreliminary validation of the extracts for bioactivity revealed that the n-hexane, DCM and MeOH extracts of the stem bark of L. eriocalyx were active against P. falciparum, A. gambie larvae, B. anthracis, and A. niger. This formed the the basis of fractionation of these crude extracts whereby lupeol (27), quercetin (65), apigenin (68) friedelin (133), -sitosterol (134), lupenone (135), -sitosterol-3-O-glucoside (136), chrysin (137) morinhydrate (138), quercetin-3-O-glucoside (13...

Additive Stabilization Of Plasmodium Proteins Present In Dried Infected Blood Specimens

ABSTRACTMalaria rapid diagnostic tests (RDTs) are a great achievement to the implementation of parasite based diagnosis before treatment. They use a nitrocellulose strip coated with antibodies that target the Plasmodium antigens; histidine rich protein II (HRP2), lactose dehydrogenase (LDH), and aldolase. A major drawback of the method is that the majority of RDTs do not have positive control materials to test different batches of RDTs at the point of care. Dried Plasmodium-infected samples w...

Antimicrobial Properties Of Tamarindus Indica Linn Leaf Extracts

ABSTRACT Tamarindus indica l leaves extract was evaluated against six bacterial strains (2 Gram-positive and 4 Gram-negative) known to cause food spoilage. Functional groups of Tamarindus indica l leaves were evaluated using the Fourier transform infrared (FTIR) spectroscopy. The leaves were extracted by the Soxhlet extraction using aqueous and organic solvents (acetone, ethanol and methanol). Stock solution of the extracts was prepared by dissolving 0.8g of each extract in 2ml dime...

Effects Of Oral Contraceptive Agents On Some Vitamins In Rats Fedon Selected Nigerian Diet

ABSTRACT Oral contraceptive agents (OCA) have been in use for well over two decades with a total of 150 to 200 million women all over the world using the pills as means of birth control. Aside from their gynecologic influences, the hormones have been shown to affect metabolic and nutritional processes. Concern over the nutritional status of Nigerian females consuming OCA prompted this research using animal model. Pour vitamins were investigated along with four birth control pills Ovr...

Response Of Avocado (Persea Americana Mill.) Rootstocks To Soil Flooding And Inoculation With Phytophthora Cinnamomi

ABSTRACTAvocado plants (Persea americana Mill.) belongs to the family lauraceae. Avocado fruit has high amounts of fats and proteins, high dietary fibre, vitamins and potassium. It is known to be the most nutritious of all the fruits. The most devastating pathogen of avocado plants is a fungal species, Phytophthora cinnamomi which cause avocado root rot. The fungus is the most widely distributed of Phytophthora species. It affects growth and physiology of plants and even leading to death of p...

Zesa Expense Reimbursement Centre

ABSTRACT Zesa Holdings employees are following long-winded expense approval processes which are delaying reimbursements. Reimbursement cycles are running into quite a lot of weeks, and sometimes even months before approvals and there is absence of proper feedback to claimants during approval workflows. The current paper-based solution for expense claim approvals has problems doing with missing claim forms and signature forgery. At the same time some employees are exaggerating field trip...

The Analysis Of Gamma Strategies For A Nonlinear Black-Scholes Equation

ABSTRACTThere has been a significant growth in research in the field of financial mathematicssince the derivation of the standard Black-Scholes-Merton PartialDifferential Equation by Black and Scholes, and Merton in 1973. The derivationwas done under the assumption that the market is liquid and frictionless(no restrictions on trade and no transaction costs). The nonlinear equationut + 12σ2S2uSS(1 + 2ρSuSS) = 0 for modeling illiquid markets has only beensolved analytically using a positive g...

A Case of Gokwe North District.

ABSTRACT The research aspired to estimate the potential damage a future flood can cause in Gokwe North District. The study made use of both quantitative and qualitative techniques to acquire data. This approach integrated GIS, remote sensing, semi-structured interviews and field observations in collecting data. Two Landsat images (path 171 row 72) for two different years (2005 and 2015) were accessed from U.S. Geological Survey’s Earth Explorer database. To analyse the LULC changes in...

Comparison Of Genexpert And Line Probe Assay For Detection Of Mycobacterium Tuberculosis And Rifampicin Mono-Resistance In Kenya

ABSTRACTTuberculosis (TB) causes substantial human morbidity and mortality globally. About 10.4 million TB cases and 1.4 million deaths worldwide were reported in 2015. Kenya is among the 22 countries with highest TB burden. Microscopy is routinely used for Mycobacterium tuberculosis bacilli (Mtb) detection; however its sensitivity has been reported to be as low as 60% posing a problem for case detection. Rifampicin (RIF) is one of the major drugs for first line TB treatment; however, most pa...

Absolutely Continuous Spectrum of Fourth Order Di erence Operators With Unbounded Coecients on the Hilbert Space `2(N)

AbstractSturm-Liouville operators and Jacobi matrices have so far been developedin parallel for many years. A result in one eld usually leadsto a result in the other. However not much in terms of spectral theoryhas been done in the discrete setting compared to the continuousversion especially in higher order operators. Thus, we have investigatedthe deciency indices of fourth order di erence operator generated bya fourth order di erence equation and located the absolutely continuousspectrum ...

Immunohistochemical Evaluation Of The Differention-Related Gene-1 Expression In And Survival Rates Of Er Breast Cancer Women Patients Attending Moi Teaching And Referral Hospital In Kenya

ABSTRACTBreast cancer is a disease that affects both men and women and currently the leading type of cancer in women globally, commanding a huge social and health impact. Approximately 52.5% of breast cancer cases express estrogen receptors (ER). ER is a receptor proteins type of breast cancer and it fuels growth of breast cancer. ER breast cancer which has been shown to be the most aggressive and misdiagnosed thus, leading to overtreatment. However, it has not been study in Africans Kenyan w...

Investigation Of Matisaa Gray Rock As A Potential Raw Material For The Manufacture Of Cement

ABSTRACTOwing to the depletion rates of coastal limestone, the characterization of cementitiousmaterials occurring on the dry land is important in order to assess their potential as alternativematerials for the manufacture of cement. In this study, a naturally occurringterrestrial rock herein referred to as “Matisaa gray rock” has been studied to determineits potential for the manufacture of cement. Matisaa gray rock is found in Matisaa village,Kitui County, Kenya, and it covers an approx...

An Investigation to Determine The Resistance of The Tick (blue tick) to Amitraz in Selected Areas of Zimbabwe.

Abstract The purpose of this study was to determine if the Boophilus species spectrum of ticks infesting cattle owned by resource limited farmers in the state owned communal land areas of Zimbabwe, are resistant to Amitraz. The study was also aimed at finding a concentration of the acaricide that the tick species are susceptible to, and can give at least 99.9% mortality. Five districts were selected from the Matabeleland South province and five farms were randomly selected from each dis...
