Prevalence of Hepatitis B serological markers among HIV infected patients

Abstract Abstract Background: Occult hepatitis B infection (OBI) is defined as serologically undetectable hepatitis B surface antigen (HBsAg-ve), despite the presence of circulating HBV DNA (Allain, 2005). It has been documented that one of the frequent complications of HIV infection is hepatitis B co-infection and due to the common methods of transmission of these two viruses, the incidence rate of co-infection is increasing (Chen et al., 2011) Objective: To determine the prevalence of HBV s...

Assessment of Alpha and Beta Radioactivity Pollution of Main Water Supplies in Dutsinma Metropolis

ABSTRACT The gross alpha and beta radioactivity pollution of main water supplies in Dutsinma metropolis were measured using proportional gas counter. The results show that the gross alpha radioactivity in water samples is lower than the maximum contaminant level of 0.1Bq/L set by World Health Organization (WHO). The measured alpha activities have a minimum of 0.001±0.0.003 and the maximum of 0.146±0.034 Bq/L with mean of 0.029±0.002 Bq/L. The gross beta radioactivity in water samples is h...

Investigating The Presence Of Staphylococcus Aureus And Escherichia Coli In Dairy Products

INTRODUCTION Dairy products are various products derived from cow’s milk or that of other female mammals such as goat, sheep, yaks, horses, camel. Dairy products include yoghurt, nono (fermented cow’s milk, madara (unfermented cow’s milk, cheese, whey, condensed and evaporated milk.) (cultureforhealth, 2015). Yoghurt, nono, Madara has become so highly valued in humans diet because of their nutritional values and their culinary possibilities (George and pamplon, 2006) Yoghurt is ma...

Application of Nented Design on the Effect of Feeds and Seasonal Variation on Dairy Milk Yield (A Case Study of Napri Shika, ABU Zaria)

ABSTRACT The present study was conducted at Ahmadu Bello University, Zaria. The aim of the study was to determine the effect of feeds (cotton seed cake, yeast supplement, cow milking ration) and seasonal variation (dry and rainy season) on dairy milk yield. A total of 21 mid lactation cows were fed with cotton seed cake, yeast supplement and cow milking ration in the two seasons respectively   and   the   volume   of   milk   produced   by   each   cow   was  recorded  �...

DESIGN AND DEVELOPMENT OF A DATABASE MANAGEMENT SYSTEM FOR STUDENT REGISTRATION

ABSTRACT This project was centered on database management system for student registration system. The current process of registration is being operated manually and due to this procedure numerous problem are been encountered. A design was taken to computerized the manual process in order to check this problem. The problems were identified after series of interviews and examination of documents after which analysis was made and a computerized procedure recommended. This project will also sugg...

ANATOMY AND WATER PURIFICATION POTENTIALS OF SEEDS OF MORINGA OLEIFERA

This study focused on elucidating the anatomy of Moringa oleifera seed and developing an efficient and cost effective procedure for using Moringa oleifera seeds to produce natural coagulant for use in drinking water treatment. The study investigates processing Moringa oleifera seeds to concentrate the bio-active constituents which have coagulation activity. It is generally accepted that Moringa works as a coagulant due to positively charged, water-soluble proteins, which bind with negatively ...

ISOLATION OF SERRATIA MARCESCENS FROM THE SOIL AND INVITRO PRODIGIOSIN PRODUCTION AS SOURCE OF ANTIBIOTIC, ACTIVE AGAINST OXACILLIN RESISTANT STAPHYLOCOCCUS AUREUS

  ABSTRACT This research work involve the isolation of two isolates titled RMN1 and RMN2, belonging to the Genus Serratia  from two soil samples collected from the following two strategic locations in university of Abuja, permanent site: Termite hill besides Girls hostel dump ground and from Faculty of Agricultural Science farm land. The isolates were morphologically distinct on the basis of spore colour, aerial and substrate mycelium formation and production of diffusible pigment. Isolat...

ISOLATION OF ANTIBIOTIC PRODUCING STREPTOMYCES FROM THE SOIL AS SOURCE ANTIBIOTICS ACTIVE AGAINST ANTIBIOTICRESISTANT STAPHYLOCOCCUS AUREUS

ABSTRACT The study involved the isolation of (2) isolates titled RMN1, RMN2,  belonging to the Genus Serratia  from ( 2) soil samples collected from the following two strategic locations in university of Abuja, permanent site: Termite hill besides Girls hostel dump ground and from Faculty of Agricultural Science farm land. The isolates were morphologically distinct on the basis of spore colour, aerial and substrate mycelium formation and production of diffusible pigment, Isolates were test...

A Palynology and paleoenvironmental Study of a Section from the Amansiodo-1 Well, Anambra Basin, Southeastern Nigeria

Abstract: Palynological analysis was carried out on twenty (20) ditch cutting samples from a section (1284.73– 1496.57 m) of the Amansiodo-1 well, Anambra Basin, southeastern Nigeria with the aim of determining the age, biozone, and depositional environment of the sediments within the depth interval. The laboratory techniques of digesting sediments in hydrochloric and hydrofluoric acids for silicates and carbonates removal were followed to process the samples for the recovery of palynomorph...

BIOETHANOL PRODUCTION FROM GROUNDNUT SHELL (Arachis hypogaea) AND CARPET GRASS (Axonopus flexuosus) BY ACID HYDROLYSIS USING Saccharomyces cerevisiae

ABSTRACT Groundnut (Arachis Hypogaea) shell and carpet grass (Axonopus flexuosus) were assessed for bioethanol production using dilute acid hydrolysis (10 %, 15 % and 20 % H2SO4) and fermentation using yeast (saccharomyces cerevisiae). The percentage yields were determined to be 27.15 %, 19.69 % and 8.79 % for groundnut shell and 22.69 %, 13.92 % and 7.69 % for carpet grass respectively. The densities of the bioethanol produced were calculated to be 0.8072 g/cm3 for groundnut shell and 0.8303...

Phytochemical Constituents and in vitro antioxidant activity of the stem bark and oil extract of Allanblackia floribunda plant

ABSTRACT This study focused on the comparative study of the phytochemical constituents, in vitro antioxidant activity of the stem bark and seed oil extracts of Allanblackia floribunda. The phytochemical screening revealed that both extracts contain flavonoids, tannins, cardiac glycosides, alkaloids and saponins while terpenoids are absent in the stem bark extract but present in the seed oil extracts. However, the quantitative studies showed that proanthocyanidin, total phenol, total tannins ...
