GEOCHEMICAL CHARACTERISTICS WITH RESPECT TO GOLD MINERALIZATION OF BENI/KAFIN-KORO AREA (PART OF SHEET 165, BISHINI SW), NORTH-CENTRAL, NIGERIA

A total of 21 samples were analyzed in the laboratory, Inductively Coupled Plasma-Atomic Emission Spectrum (ICP-AES) was employed in the whole rock analysis for oxides, total sulphide (TOS), total carbon (TOC) and loss on ignition (LOI), while Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) was employed in the analysis for trace metals including gold, and rare earth elements (REE) that were either associated with or served as pathfinder for gold. Statistical analyses revealed an anomaly...

Antimicrobial Activity, Chemical Compositions and Proximate Analysis of Ixora Coccinea L. Leaves on Some Clinical Pathogens

Plants derived bioactive compounds have been the centre of recent owing to their health promoting effects. An attempt was made in evaluating the phytochemical, minerals, proximate and anti-microbial activity of analyses standard agar well diffusion method saponins, tannins, flavon minerals analysis revealed the presence of manganese and phosphorus.

Epilepsy and Ethno Medicinal Plant in Hausa/Fulani tribe

Introduction Epilepsy is a common medical and social disorder or group of disorders with unique characteristics. Epilepsy is usually defined as a tendency to recurrent seizures. The word “epilepsy” is derived from Latin and Greek words for “seizure” or “to seize upon”. This implies that epilepsy is an ancient disorder; indeed, in all civilizations it can be traced as far back as medical records exist. In fact, epilepsy is a disorder that can occur in all mammalian species, probabl...

STUDY ON PHYTOCHEMICAL SCREENING AND PROXIMATE ANALYSIS OF CENTAUREA PRAECOX Oliv and Hiern

ABSTRACT Phytochemical and proximate analyses were carried out on leafy stem and flower head extract of Centaurea praecox grown in Sokoto, using standard methods. The result of phytochemical analysis shows that the flower head contain 1.67mg/100g Alkaloid, 2.50mg/100 saponins, 5.20mg/100g flavonoid, 4.07mg/100g Steroid. The proximate analyses revealed that the flower head contain 3% moisture, 11.5% Ash, 3% crude lipid, 3.5% crude protein, 25% crude fibre and 57% carbohydrate. The mineral anal...

Antimicrobial Properties, Phytochemical Composition,and Phenotypic Resistance Pattern of Selected Enteropathogenic Microorganism on Ageratumconyzoides (Goat Weed) Leaf Extract

The aim of this study is to determine the phytochemical composition, antimicrobial properties and phenotypic resistance pattern of selected enteropathogenic micro organism on Ageratum conyzoides leaf extract. Enteropathogenic isolates were collected from Adekunle Ajasin University Health Centre, Akungba Akoko, Ondo State and were identified using Microbact™ 24E Identification kit. Antibiotic sensitivity testing was carried out against the enteropathogenic organism using Kirby-Bauer disc dif...

The Concept of Nonribosomal Peptide Sythetases: Industrial Application in Biosynthesis of Antibiotics

Abstract Nonribosomal peptide synthetases (NRPSs) are multimodular enzymes that are used wholly or partly in the biosynthesis of antiobiotics; a natural product that fall into the class of secondary metabolites. NRPSs have diverse functions and have also been used in the synthesis of toxins, siderophores, or pigments, among others. Unlike other proteins, its biosynthesis is independent of ribosomal machinery. Nonribosomal peptides are synthesized on large nonribosomal peptide synthetase�...

CLINICAL TRIAL REGULATION IN NIGERIA AND NAFDAC

This work describes the role of NAFDAC in the regulation of clinical trials in Nigeria. Clinical  trials  are  experiments  or  observation  done  in  clinical  research. Such prospective biomedical  or  behavioural  research  studies  on human participants are  designed  to  answer  specific  questions  about  biomedical  or behavioural  interventions,  including  new treatments (such  as novel vaccines, drugs, dietary choices, dietary supplements and medical device...

Comparative Study Between the Eect of Parkia Biglobosa (JACQ) benth and Conventional Antibiotics Against Multiple Antibiotic Resistant Uropathogenic Bacteria (MARUB)

The purpose of this work is to compare the effect of convectional antibiotics with medicinal plant (Parkia biglobosa (Jacq.)Benth) against multiple antibiotics resistant Uropathogenic bacteria isolates.(MARUB), which was isolated from basically two hospital in Ondo State, Nigeria. The two hospitals are Gani Fawehinmi Diagnostic center, Ondo and Federal Medical Center, Owo between July, 2017 and October, 2017. fifty two (52) Gram negative bacteria isolated from urine of UTIs patient at the Gan...

Estimation of Global Solar Radiation Flux Over Ibadan

Renewable energy resources are those having a cycling time less than 100 years and are renewed by the nature and their supply exceeds the rate of consumption. Renewable energy systems use resources that are constantly replaced in nature and are usually less polluting. This project work estimates the solar radiation flux over Ibadan, a south-western city in Nigeria. The estimated models for the solar radiation over Ibadan are obtained for the period of ten years (1995 to 2004). The solar radia...

Indoor Gamma Dose Rate Exposure Levels in the Faculty of Science, University of Ibadan

Building materials are one of the potential sources of indoor radioactivity because of the naturally occuring radionuclides in them. Exposure to indoor ionizing radiation, like gamma radiation, results in critical health challenges. This work was designed to assess the indoor gamma dose rate level following the renovations of offices of lecturers in Faculty of Science, University of Ibadan using RDS-30 Survey meter. Measurements were made at 110 locations after renovations and in some selecte...

Zones of Inhibition and Molecular Docking (In-silico Approach) of Piptadeniastrum africanum Extracts on Clinical and Multiple Antibiotic Resistant Isolates

The use of plants as medicines is an ancient practice common to especially Nigeria and Africa at large. The purpose of this research work is to evaluate the zones of inhibition, phytochemical screening and molecular docking (In-silico Approach) of Piptadeniastrum africanum against selected clinical and multiple antibiotic resistant isolates. Using agar well diffusion method, the antimicrobial activity of the stem bark and leaf extracts of Piptadeniastrum africanum was assayed against Escheric...

Antibacterial Activity of Garlic (ALLIUM SATIVUM) on Staphylococcus aureus and Escherichia coli

The study was carried out to evaluate the antibacterial potential of ethanolic and aqueous extracts of Garlic on Staphylococcus aureus and Escherichia coli by serial dilution in molten agar. The result of the study showed that both aqueous and ethanolic extracts inhibited the growth of the test organisms and hence their potential for the development of novel classes of antibiotics. 

Radon soil–gas as a geological mapping tool: case study from basement complex of Nigeria

Abstract  In an effort to quantify thegeogenic radon soil–gas potentialand appraise the use of radon tech-nique as a geological mapping toolin a crystalline basement rock terrain of Ile–Ife Nigeria, radon measure-ment concentration were made usinga radon detector instrument (EDARD-200) that measures radon isotopes by a scintillator cell coupled to a photo multiplier tube. The data were collected from soils derived from three different lithologic rock units. The observed values were the...

TIME SERIES ANALYSIS ON SOME SELECTED NON OIL PRODUCE IN NIGERIA (A CASE STUDY OF CASH CROPS & LIVESTOCK)

ABSTRACT           In the period of the 1970’s, Agriculture was the main stay of the Nigeria economy. The oil boom of 1970’s brought about a gradual shift from agriculture to crude oil making Nigeria to depend heavily on petroleum as main source of foreign exchange earnings. Agriculture sector which use to be the back bone of the economy was rendered competitive over time. The crux of this study is to analyze the revenue generated from selected non-oil produce in Nigeria. Dat...

STEM AND ROOT ROT DISEASES OF CUCUMBER

ABSTRACT Cucumber has been an essential vegetable crop in the world being affected by Pythium, fusariium and phythophtora. Root and stem rot of cucumber (Cucumis sativus), caused by Fusarium oxysporum f. sp. radicis-cucumerinum, is a new catastrophic disease of greenhouse crops in Greece and some other countries Fusarium oxysporum causes rotting of roots, lower stems and pythium also causes seedling damping off which is widely spread across cropping soils. Fusarium root and stem rot occur mos...
