A new study by researchers at UC Davis Medical Center suggests that the sudden unexplained deaths of some epilepsy patients may be a result of their brains not telling their bodies to breathe during seizures.

| • | First Detailed 3-D Glimpse Of Bacterial Cell-wall Architecture | |
| The bacterial cell wall that is the target of potent antibiotics such as penicillin is actually made up of a thin single layer of carbohydrate chains, linked together by peptides, which wrap around the bacterium like a belt around a person, according to scientists at the California Institute of Technology. This first-ever glimpse of the cell-wall structure in three dimensions was made possible by new high-tech microscopy techniques. | ||

| • | Antimicrobial activity of endemic Crataegus tanacetifolia (Lam.) Pers and observation of the inhibition effect on bacterial cells | |
| Up to now an increasing number of antibiotic-resistant bacteria have been reported and thus new natural therapeutic agents are needed in order to eradicate these pathogens. Through the discovery of plants such as Crataegus tanacetifolia (Lam.) Pers that have antimicrobial activity, it will be possible to discover new natural drugs serving as chemotherapeutic agents for the treatment of nosocomial pathogens and take these antibiotic-resistant bacteria under control. The objective of the present study was to determine antimicrobial activity and the activity mechanism of C. tanacetifolia plant extract. The leaves of C. tanacetifolia, which is an endemic plant, were extracted using methanol and tested against 10 bacterial and 4 yeast strains by using a drop method. It was observed that the plant extract had antibacterial effects on Bacillus subtilis, Shigella, Staphylococcus aureus, and Listeria monocytogenes among the microorganisms that were tested. Minimum inhibitory concentration (MIC) results obtained at the end of an incubation of 24 h were found to be [ge]6.16 mg ml-1 for B. subtilis, <394 mg ml-1 for Shigella, and [ge]3.08 mg ml-1 for L. monocytogenes and S. aureus and minimum bactericidal concentration (MBC) were found as [ge]24.63 mg ml-1 for B. subtilis, [ge]394 mg ml-1 for Shigella, [ge]6.16 mg ml-1 for L. monocytogenes, and [ge]98.5 mg ml-1 for S. aureus. According to the MBC results, it was found that the plant extract had bactericidal effects and in order to explain the activity mechanism and cell deformation of bacterial strains treated with plant extract, the scanning electron microscopy (SEM) was used. The results of SEM showed that the treated cells appeared shrunken and there was degradation of the cell walls. This study, in which the antibacterial effect of C. tanacetifolia was demonstrated, will be a base for further investigations on advanced purification and effect mechanism of action of its active compounds.

| • | 1000 citrus flowers | |
| There must be 1000+ flowers on our potted mandarin orange tree this year. That is pretty sensational flower power when you consider it is growing in a 14 inch diameter pot. Having been fed from summer to spring with Triplantanol and sitting outside on the patio in full UK sunshine it has flowered most of the summer. However the number of flower buds seem to have increased far in excess of what we expected. The perfume is quite sensational. Full information on citrus feeding can be found by exploring out site under the section 'specialist plants'. The plant in question normally just produces a nice display of 20-50 flower buds, but we have never seen anything like this seasons results. | ||
