DISSOLUTION ENHANCEMENT OF POORLY WATER SOLUBLE EPROSARTAN BY HOT MELT EXTRUSION TECHNIQUE
Objective: The prodigious challenge in the pharmaceutical industries was to enhance the solubility and the permeability of those drugs as key factors to improve their bioavailability. Various techniques have been used to improve the drug water solubility and release profile, and solid dispersions are considered to be the most successful techniques. The aim of the present study was to improve the s...

BIOFILM INFECTIONS: A NEW THERAPEUTIC CHALLENGE
Biofilms are multicellular communities of bacteria. The ability to form biofilm is a universal attribute of bacteria and as bacteria can form biofilm in medical, industrial and environmental settings, it impacts human lives in many different ways. Bacteria undergo profound physiologic, morphologic and genetic changes as the transit from planktonic (free swimming, non-biofilm) form to surface attac...

CYCLODEXTRIN GLYCOSYLTRANSFERASE PRODUCTION BY ALKALIPHILIC BACILLUS SP. ISOLATED FROM RICE CULTIVATED SOIL AND MEDIA OPTIMIZATION USING TAGUCHI METHOD
A Cyclodextrin glycosyltransferase (CGTase) producer was isolated from soil obtained from rice fields using alkaline Horikoshi II medium. The alkaliphile was characterized microscopically, biochemically and confirmed by 16S rRNA analysis as Bacillus oshimensis. CGTase production is dependent on the strain, medium composition and culture conditions; hence media optimization studies were carried out...

ANTIOXIDANT ACTIVITY OF HONEY SAMPLES FROM THE SOUTHERN RAINFOREST AND NORTHERN SAVANNAH ECOSYSTEMS IN NIGERIA
Selected physicochemical parameters, total phenolics, flavonoids and free radical scavenging activity of honey samples from the northern savannah region and southern rainforest ecosystems of Nigeria were investigated. Moisture and ash content of most samples were within acceptable limits. Total phenolic content ranged from 23.92 to 82.34mgGAE/100g for both ecosystems. Flavonoids varied between 2.5...
