Using standard WHO methodology, this study investigated the susceptibility of 4th instar Aedes aegypti (L) and Culex annulirostris (Skuse) larvae to three extracts from Callitris glaucophylla (J. Thompson & L. Johnson) (1: steam distillation extract, 2: liquefied refrigerant gas extract, and 3: methanol reflux extract), lambda-cyhalothrin (a synthetic pyrethroid insecticide) and fenitrothion (a...

There are many remediating methods for the polluted soils but only phytoremediation is a cost effective, environmental friendly, aesthetically pleasing approach that is most suitable for many countries. The purpose of this study was to investigate the potential of native plants for phytoremediation of contaminated soils with lead, zinc, cadmium and nickel in the rangelands around National Lead ...

Adult male rats were given an oral dose of 10 mgkg aspartame “C-1abelled in the methanol carbon. At timed intervals of up to 6 hours, the radioactivity in plasma and several organs was investigated. Most of the radioactivity found (>98 % in plasma, >75 % in liver) was bound to protein. Label present in liver, plasma and kidney was in the range of l-2 % of total radioactivity administered per g ...

Chemoprevention provides an important strategy for cancer control in passive smokers. Due to the crucial role played by smoke-related chronic inflammation in lung carcinogenesis, of special interest are extensively used pharmacological agents, such as nonsteroidal anti-inflammatory drugs (NSAIDs). We evaluated the ability of aspirin and naproxen, inhibitors of both cyclooxygenase-1 and cyclooxy...

The implantation process is complex, requiring reciprocal interactions between implantation-competent blastocysts and the receptive uterus. There were reports to show that some microRNAs (miRNAs) may play a key role during embryo implantation in mouse. However, the miR-320 expression profiles in the rat uterus during peri-implantation are unknown. In the present study, we found that the express...

The Suzuki cross-coupling reaction is about 30 years old and represents a smooth method for creating carbon-carbon bonds. Typically, in the Suzuki reaction aryl halides are combined with an aryl boronic acid or boronic ester in the presence of a Pd(0) catalyst and base to afford a variety of biaryl compounds (Scheme 1). These biphenyl templates are very common in non-steroidal anti-inflammatory...

Stable isotope analyses of discrete seasonal layers from a 108-yr annually laminated freeze-core from Baldeggersee, a small, eutrophic lake in central Switzerland, provide information on the climatological and environmental factors, including lake eutrophication, that control oxygen and carbon isotopic composition of epilimnic biologically induced calcite precipitate. During the last 100 yr, Ba...
