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. ... -
Cholinergic neurons regulate secretion of glial cell line-derived neurotrophic factor by skeletal muscle cells in culture.
(Elsevier, 2011-05-16)Glial cell line-derived neurotrophic factor (GDNF) has been identified as a potent survival factor for both central and peripheral neurons. GDNF has been shown to be a potent survival factor for motor neurons during ... -
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 ... -

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 ... -
Nuclear Factor kappa B is central to Marek’s Disease herpesvirus induced neoplastic transformation of CD30 expressing lymphocytes in-vivo
(BMC Systems Biology, 2012)Background: Marek’s Disease (MD) is a hyperproliferative, lymphomatous, neoplastic disease of chickens caused by the oncogenic Gallid herpesvirus type 2 (GaHV-2; MDV). Like several human lymphomas the neoplastic MD lymphoma ... -
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 ... -
The effect of plant extracts as seed treatments to control bacterial leaf spot of tomato in Tanzania
(Springer Nature, 2012-05-05)Bacterial leaf spot (BLS) caused by seed-borne xanthomonads is a serious disease of tomato (Solanum lycopersicum L.), causing significant losses in both yield and quality. To identify more effective control measures, we ... -
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 ... -
