Proteolytic Activity In Adult Haemonchus Contortos

ABSTRACT , Proteolytic activity of theJQ.qOOxgsupernate of homegenates ef adult Haemonchus contortus has been studied with respect to substrates susceptible to its proteolytic activity, and the effects of factors such as temperature, pH, substrate concentration, extract concentration, dibasic metal ions, detergents, heat and some specific inhibitors of proteolytic activity. The supernate had two pH optima, 5.6 with haemoglobii as substrate, and 7.8 using L-alanyl - p-nitroanilide. It showed o...

Characterization And Genotyping Of Rotaviruses From Communities In Akuse District And Its Environs

ABSTRACT Background: Rotaviruses are recognised world-wide as the principal aetiological agents of severe neonatal diarrhoea in a number of species, including man and domestic animals. Eight species of this virus have been detected and classified as A, B, C, D, E, F, G and H. Human beings are predominantly infected by species A, B and C, but A–E species cause disease in other animals. Studies in Ghana have reported new emerging strains of the virus in paediatric diarrheal cases some of whic...

Time Series Analysis Of Maternal Mortality In Ghana. A Case Study Of The Korle-Bu Teaching Hospital, Accra (2001 - 2013)

ABSTRACT This study examined the pattern of maternal mortality ratios as well as a spectral analysis of maternal mortality at the Korle - Bu Teaching Hospital in Accra from 2001 to 2013. It also fitted a stochastic model to forecast maternal mortality ratios for four quarters. Analyses were based on data available at the Bio-Statistics Department of the Obstetrics & Gynaecology directorate of the Korle - Bu Teaching Hospital in Accra for the period 2001 – 2013. The R-Consol statistical anal...

Synthesis, Characterization And Luminescent Properties Of Bipodal And Tripodal Pyrazole And Triazole Lanthanide Coordination Complexes,

ABSTRACT Lanthanide complexes have been established as promising agents in their application as catalysts and photo-luminescent materials. Recent research has been geared towards the optical application of these lanthanide complexes, especially as organic light-emitting diodes (OLED) for TV screens, phones and other portable electronic devices. The luminescent ability of these complexes is largely dependent on the choice of ligand environment. We report here for the first time lanthanide comp...

Statistical Analysis Of Water Level, Temperature And Humidity Using Cointegrated Vector Autoregression (Var) Models.

ABSTRACT The leading climate factors influencing availability of water are; temperature, relative humidity, precipitation, and evaporation. Water and agricultural production cycles are indisputably influenced by temperature and relative humidity. Temperature and relative humidity projections can therefore proficiently be employed in making decisions when optimal usage of water resources is of interest. Thus, the current study explored both the “long-run” and “short-run” impact of both...

Statistical Modelling Of Birth Spacing And Reproductive Health Of Married Women From Gomoa East District In The Central Region Of Ghana: A Survival Analysis Approach

ABSTRACT The objective of this research is to apply appropriate statistical techniques to model the length of time to successive births (birth spacing) within the reproductive health of mothers and identify the socio-demographic and sociocultural factors that cause variation in the length of birth interval. The data used in this study were collected using questionnaire from Gomoa East District 2014, where multi-stage cluster sampling was used as the sampling design. The clusters were defined ...

Effects Of Pollution On Coastal Environment And Socio-Economic Life Of The People Of Elmina

ABSTRACT Coastal pollution is not only a serious threat to the coastal ecosystem but also to the life of those living there and depending on the coastal environment for their livelihood activities. The research examined the causes and effects of coastal pollution on socio-economic life of the people of Elmina as well as measures to mitigate the problem. A model of conceptual frame work showing circular inter-relationship among causes, environmental and socioeconomic effects and solutions of c...

ABSTRACT Malaria control has received significant attention in the Akwapim South Municipality yet remains the highest cause of ill-health among the people. Not only must interventions be put in place but they must actually be effective in ensuring that malaria morbidity and mortality are eliminated. There have been series of strategies that have been implemented under the malaria control programme to control and prevent malaria. Despite the fact that interventions have been introduced, their ...

Evaluation Of Medicines For Malaria Venture (Mmv) Compound Library For Potency Against P. Falciparum Clinical Isolates

ABSTRACT The resistance of Plasmodium falciparum to artemisinin and its derivatives underscore the need for new sets of antimalarials with novel mechanisms of action. Towards the development of new, affordable and easily accessible antimalarial drugs for endemic regions, there is the need to screen more compounds for their antimalarial activity. Several studies on different compound classes have been conducted using laboratory strains of P. falciparum. However, not much is known of their pote...

The Sedimentology Of Gambaga Massifs Of The Northeastern Voltaian, Ghana.

Abstract The sedimentary facies of the investigated area of the northeastern Voltaian, with respect to the sedimentary structures, composition as well as the depositional environments, can be classified into six (6) facies. The sediments are deposited dominantly in a shallow marine environments with records of shoreface/foreshore, Aeolian and tidal environments. The sediments were deposited in the various environments by both low and high energy media. The area shows a shallowing and thickeni...

Potentially – Zoonotic Viruses In The Straw-Colored Fruit Bat (Eidolon Helvum) In Ghana

ABSTRACT Bats are reservoirs for many emerging zoonotic RNA viruses, including rabies virus (RABV), SARS-like coronavirus, henipaviruses and filoviruses. Several bat species have been associated with Lagos bat virus (LBV) infection. They include Wahlberg‟s epauletted fruit bat (Epomorphorus wahlbergi), the straw-colored fruit bat (Eidolon helvum), the Egyptian fruit bat (Rousettus aegyptiacus), and an insectivorous bat, the Gambian slit-faced bat (Nycteris gambiensis). Bats are important fo...

Mapping Urban Place And Space: Fear Of Crime And The Re-Configuration Of Occupational Geographies In Tamale, Ghana.

ABSTRACT Throughout history, studies have amply revealed that where people choose to settle within the urban space is not new. This has been explained to be an important part of the urbanisation process. Effect of fear of crime on the urban environment especially that which involves the re-location of activities and the restructuring of the built environment as an impact factor response strategy is less acknowledged in urban security scholarship especially in developing countries. Rather, con...

Interactions Of Antimicrobial Compound With Selected Drugs Used In The Clinical Management Of Sickle Cell Disease

ABSTRACT Though the promotion of resistant bacteria worldwide has mainly been attributed to the injudicious use of many antibiotics, the role of non-antimicrobial drugs used in the clinical management of pathological conditions of non-infectious diseases in the modulation of microbial drug resistance or susceptibility needs to be assessed. The effects of the antibioticnon- antibiotic drug-drug interactions against bacteria in SCD patients and in other chronic diseases cannot be overemphasized...

MOLECULAR CHARACTERIZATION OF TICK-BORNE PARASITES IN NATURALLY INFECTED CATTLE IN ACCRA AND ADIDOME, GHANA

ABSTRACT Tick-borne pathogens and ticks pose significant problem to livestock production especially cattle production. This causes huge economic decline to livestock farmers in tropic and sub-tropic regions of Africa. The most economically important tick-borne pathogens to the production of bovine include Babesia, Anaplasma, Theileria and Ehrlichia. In Ghana, inadequate data exists on the species and genetic diversity of tick-borne hemoparasites. The current study was conducted to detect and ...
