PRODUCTION OF XYLANASE BY PENICILLIUM SP. AND ITS BIOBLEACHING EFFICIENCY IN PAPER AND PULP INDUSTRY
The main objective of this study is to evaluate the ability of production of xylanase by a fungal strain Penicillium sp. isolated from decaying wood. Xylanases are hydrolytic enzymes produced by many microorganisms which catalyze the hydrolysis of xylan polymer to xylose monomer. The xylanase production was carried out under submerged fermentation xylose as the main substrate, and the enzyme yield...
Background: Plants and herbs consumed by humans are the rich sources of phytonutrients compounds synthesized in plants itself. Such bioactive substances are responsible for the plant’s antioxidant and medicinal values. Flavonoids are an essential group of naturally occurring polyphenolic compounds, and its flavan nucleus characterizes it. It is one of the most common classes of compounds availab...
SYNTHESIS, IN-SILICO PHYSICOCHEMICAL PROPERTIES AND ANTIMICROBIAL STUDIES OF PYRAZOLINE LOADED NANOPARTICLES
Pyrazolines were prepared from the corresponding chalcones by using isonicotinylhydrazine as cyclizing agent. The synthesized compounds were characterized by spectral data and screened for antimicrobial activity. In-silico studies of physiochemical and drug-like properties revealed that these compounds have good bioavailability and drug-likeness properties. Compound PZ2 which exhibited good antimi...
A new, simple, safe, accurate and reproducible spectrophotometric analytical method was developed for the quantitative estimation of gatifloxacin in solid dosage form by mixed hydrotropic agents. The enhancement of solubility of drug gatifloxacin was more than 15 fold in mixed hydrotropic solution (20% N,N dimethyl urea and 20% sodium citrate solution) as compared to solubility in distilled wate...
Cyclobenzaprine hydrochloride (CBZ) is a muscle relaxant. It has 33% bioavailability due to its first pass effect and hence posses problems in the development of oral sustained release formulations. Mucoadhesive thermo reversible in-situ nasal gel of Cyclobenzaprine HCl was designed and developed to sustain its release due to the increased nasal residence time of the formulation. Poloxamer 407 (PF...
The potential of methanol extract as a potent antimicrobial agent has been observed to be an effective means to combat disease causing pathogenic organisms. Growth pattern of Escherichia coli cells showed that the growth of cells decreased with an increase in concentration of extract. The specific relationship between the specific growth rate and the substrate concentration was thus be obtained by...
ACUTE ORAL TOXICITY AND NEUROBEHAVIOURAL TOXICOLOGICAL EFFECTS OF METHANOLIC EXTRACT OF CHRYSOPHYLLUM PERPULCHRUM IN RATS
This study aimed to investigate the acute toxicity of methanolic extract of Chrysophyllum perpulchrum on biochemical, behavioral and histopathological variation in male Wistar rats. Acute toxicity of the methanol extract of Chrysophyllum perpulchrum was carried out on 36 male rats using different doses of the extract ranging from 500 to 2000 mg/kg body weight. Behavioral tests were used to determi...
Lycopersicon esculentum leaves had traditionally been used to stimulate hair growth in Lampung Pesisir tribes, Tanggamus Regency, Lampung, Indonesia. This study aimed to examine the active compounds from the n-hexane L. esculentum leaves. The study based on our previous research showing that the n-hexane had hair growth stimulating effects. The study started with sample collection, extracted by ma...
Adenocalymma alliaceum is an important medicinal plant belongs to the family Bignoniaceae. The antibacterial and phytochemical studies on the leaves of this plant were carried out by using the disc diffusion method and Thin Layer Chromatography. The methanolic leaf extract showed a brown colored band on TLC plate with an Rf value 0.25 represents the presence of sulfide compound. The extract was te...
THE UNDERSTANDING AND ADHERENCE OF HIV-INFECTED PREGNANT WOMEN TO THERAPY IN A SOUTH-EASTERN STATE OF NIGERIA: A CROSS-SECTIONAL ASSESSMENT
Introduction: Appropriate understanding and adherence to antiretroviral regimens are important requisites to the presentation of good outcomes in the Prevention of Mother-to-Child Transmission (PMTCT) of HIV/AIDS. Objectives: This study aimed to evaluate the understanding and level of adherence to antiretroviral regimens among HIV-infected pregnant women. The factors that affect the level were als...
