Modifications of the hydrophilicity of heterocyclic methacrylate copolymers for protein release
(Elsevier, 1995-12)A series of copolymers comprising ethyl methacrylate (EM) and tetrahydrofurfuryl methacrylate (THFMA) gelled with either THFMA monomer or hydroxyethyl methacrylate (HEMA) monomer have been developed. In this paper, we ... -
The water uptake of poly(tetrahydrofurfuryl methacrylate)
(Elsevier, 1999-03)Poly(tetrahydrofurfuryl methacrylate) possesses some unique characteristics with respect to its biocompatibility and behaviour in water. The water uptake is high (>70%) and very slow (over 3 yr), but the material remains ... -
A polymeric system for the intra-oral delivery of an anti-fungal agent
(Elsevier Science Ltd., 2001)Oral candidal infections are often persistent and intractable and thus the aim of this study was to develop a polymeric sustained release device to improve the topical treatment of these infections. A self curing system ... -
Mycobacterium bovis in rural Tanzania: Risk factors for infection in human and cattle populations
(Elsevier Ltd., 2007-01)Although bovine tuberculosis is widespread throughout Africa, very little is known about risk factors for Mycobacterium bovis infection in either human or cattle populations. A human case–control study was conducted in ... -
Germination of Invasive Plant Seeds after Digestion by Horses in California
(Natural Areas Journal, 2008-10)Using a unique sterile design intended to eliminate outside seed contamination of horse feces, we investigated whether weed seeds germinate after digestion by horses. Feces were collected from selected National Parks and ... -
Rooting and growth potential of Leucadendron laxum (proteaceae) using different rooting mediums and indoleacetic acid growth regulators
(Sabinet African Journals About Sabin, 2009-01-01)Leucadendron laxum (Proteaceae) is a South African plant species with a high commercial value as a flowering potted plant. Limited research information on the culture and propagation of this species is available in South ... -
Occurrence of patulin in various fruit juices from South Korea: An exposure assessment
(Springer Nature Switzerland AG., 2010-02-28)To determine patulin in various fruit juices, high performance liquid chromatography (HPLC) method was optimized and validated. For validation of HPLC method, a linearity, accuracy, precision, detection limit, and ... -
In vivo uptake and acute immune response to orally administered chitosan and PEG coated PLGA nanoparticles
(Elsevier, 2010-09-17)Nanoparticulate drug delivery systems offer great promise in addressing challenges of drug toxicity, poor bioavailability and non-specificity for a number of drugs. Much progress has been reported for nano drug delivery ... -
In vivo evaluation of the biodistribution and safety of PLGA nanoparticles as drug delivery systems
(Elsevier Inc., 2010-10)The remarkable physicochemical properties of particles in the nanometer range have been proven to address many challenges in the field of science. However, the possible toxic effects of these particles have raised some ... -
Enhanced use of beneath-canopy vegetation by grazing ungulates in African savannahs
(Elsevier B.V., 2010-12)The cover of large trees in African savannahs is rapidly declining, mainly due to human land-use practices. Trees improve grass nutrient quality and contribute to species and structural diversity of savannah vegetation. ... -
A preliminary study of T-2 and HT-2 toxins in cereals sold in traditional market in South Korea
(Elsevier Ltd., 2011-08)Fusarium species are responsible for the production of harmful trichothecenes mycotoxins in cereals. These mycotoxins are cytotoxic, potentially immunosuppressive and potent fast-acting inhibitors of protein and nucleic ... -
Production of Coturnix quail immunoglobulins Y (IgYs) against Vibrio parahaemolyticus and Vibrio vulnificus
(Springer Nature Switzerland AG., 2011-12-31)Production of chicken immunoglobulins Y (IgYs) and their applications in prophylactic, therapeutic, detection of microbial contaminants and as a diagnostic tool has been widely studied with limited information from other ... -
Exercise-dependent regulation of glial cell line-derived neurotrophic factor (GDNF) expression in skeletal muscle and its importance for the neuromuscular system
(Higher Education Press and Springer-Verlag Berlin Heidelberg, 2012)The focus of this review is to highlight the importance of glial cell line-derived neurotrophic factor (GDNF) for the motor nervous system. GDNF is the most potent survival factor for motor neurons, where it enhances maintenance ... -
Effects of protein binding on the biodistribution of PEGylated PLGA nanoparticles post oral administration
(Elsevier B.V., 2012-03-15)The surface of nanoparticles is often functionalised with polymeric surfactants, in order to increase systemic circulation time. This has been investigated mainly for intravenously administered nanoparticles. This study ... -
Resistance of Bacillus cereus and its enterotoxin genes in ready-to-eat foods to γ-irradiation
(Springer Nature Switzerland AG., 2012-04-30)This study was investigated the resistance of Bacillus cereus ATCC 13752 and its enterotoxin coding genes in cereals, vegetables, and tryptic soy broth to γ-irradiation. Screening for enterotoxin coding genes, viability ... -
Porous Polyethylene Composite as Biomass Carrier for Red Pigment Production Using Monosodium Glutamate Wastewater as Medium
(American Scientific Publishers, 2012-10-01)Abundant acidic wastewater from monosodium glutamate production is difficult to treat, leading to serious water pollution. Utilization of monosodium glutamate wastewater (MSGW) with high concentration of COD (33170 mg/L) ... -
Design and formulation of nano-sized spray dried efavirenz-part I: influence of formulation parameters
(Springer Nature Switzerland AG., 2012-10-25)Efavirenz (EFV) is one of the first-line antiretroviral drugs recommended by the World Health Organisation for treating HIV. It is a hydrophobic drug that suffers from low aqueous solubility (4 μg/mL), which leads to a ... -
Preparation of rifampicin/lactose microparticle composites by a supercritical antisolvent-drug excipient mixing technique for inhalation delivery
(Elsevier, 2013-02)Rifampicin (RIF) is precipitated in the presence of inhalable lactose particles using a supercritical antisolvent-drug excipient mixing (SAS-DEM) technique to create RIF/lactose microparticle composites intended to improve ... -
Efficiency of fractionated γ-irradiation doses to eliminate vegetative cells and spores of Bacillus cereus from raw rice
(2013-04-30)Efficacy of fractionated γ-irradiation to eliminate vegetative and spore forms of Bacillus cereus from raw rice was studied. Viable bacteria and spores count performed after irradiation treatment revealed that vegetative ... -
