Comparitive activities and mechanisms of action of three novel antiulcer agents
Antiulcer agents, notably inhibitors of gastric acid secretion, have been the most successful category of drugs to be discovered in recent years; and moreover, there are currently four such agents in the world list of top 25 best selling drugs. Histamine H2 antagonists have been the number one …

Signal transduction pathways involved in skeletal muscle fibre type regulation
Mature skeletal muscle fibres can be classified as type 1, type Ha, type IIx or type IE[b fibres according to the myosin heavy chain (MIHQ isoform that they express. More broadly, type I fibres are classified are slow fibres and type Ha, IIx and 11b fibres as fast fibres. However, the phenotype of …

The effects of anaesthetic agents on synapses of lymnaea stagnalis (L.)
… an invertebrate model system, something which cannot readily be done in vertebrate systems. This was achieved by carrying out experiments using both the above mentioned anaesthetics on the whole animal, isolated brain and cultured neurons. In invertebrates it has been shown that GABA and Glutamate …

Effect of insulin and momordica charantia fruit juice extracts on glucose and ion transport in L6 rat muscle cell line
… reduced calcium (Ca 2 ) efflux, although it was not significant. Likewise, the islet hormone had no significant effects on magnesium (Mg 2 ) transport. On the other hand, the different concentrations of A and B extracts had little or no effect on cation transport, with exception for sodium (Na t) …

Expression profile of multidrug resistance genes and proteins in cancerous and stem cells
… characterise the association with MDR related genotype and phenotype. The chemosensitivity of the isolated CD 133 population was investigated using chemosensitivity assay. Meanwhile, a serum deprivation method was established in this study to enrich and select CD 133+ CSCs in a glioma (GOS-3) …

The use of lipid profiles from immobilised selenastrum capricornutum in the biological surveillance of freshwaters
… cells than free cells, thus gel confinement did not confer any protection to cells. The characteristic and significant changes within the lipid composition of free cells with Cu treatment were similarly observed in immobilised cells but were only apparent at 124 pM Cu. Thus lipid profiles, …

The effect of photoperiod on central steroid receptor expression and plasma hormone concentration in the ring dove (Streptopelia Risoria)
The hormonal control of the ring dove (Streptopelia risoria) breeding cycle is well established and influenced by photoperiod. This present study was designed to investigate the influence of photoperiod upon plasma prolactin and luteinizing hormone (LH) concentrations, together with the expression …

A comparison of different methods of determination of amino acid profiles in mammalian tissues: a study of teratogenic effects of vigabatrin and alcohol
Amino acid analysis has been used extensively as a biochemical tool for the diagnosis and monitoring of amino acid levels in normal and diseased conditions resulting from inborn errors of metabolism. Normaly, a volume of 1 ml of venous blood is often recommended but this is a serious problem when …

An investigation into unexplained primary postpartum haemorrhage
… and internationally, since if bleeding is not controlled major organ failure may result, leading to maternal death or severe morbidity in the women who experience this traumatic event. Postpartum haemorrhage is defined as bleeding from, or into the genital tract after the birth of the baby …

Optimization of automated immunomagnetic separation for the detection of escherichia coli 0157: H7 by quantitative polymerase chain reaction
Escherichia coil 0157:1-17 is a virulent human pathogen responsible for severe bloody diarrhoea, haemorrhagic colitis and haemolytic uraemic syndrome. Carriage of the organism through the food chain can result in contamination of raw meat, dairy products, crops and produce during production. …
