We analyzed the chromosome region of Streptococcus pneumoniae located downstream of the division and cell wall (dcw) cluster that contains the homolog of the Bacillus subtilis cell division gene divIVA and some genes of unknown function. Inactivation of divIVA in S. pneumoniae resulted in severe growth inhibition and defects in cell shape, nucleoid(More)
Diacylglycerol kinases are key modulators of levels of diacylglycerol, a second messenger involved in a variety of cellular responses to extracellular stimuli. A number of diacylglycerol kinases encoded by separate genes are present in mammalian genomes. We have cloned cDNAs encoding several isoforms of the human homologue of the rat diacylglycerol kinase(More)
Brain derived neurotrophic factor (BDNF) has been shown to exert multiple actions on neurons. It plays a role in neuronal growth and maintenance and use-dependent plasticity, such as long-term potentiation and learning. This neurotrophin is believed to regulate neuronal plasticity by modifying neuronal excitability and morphology. There is experimental(More)
In order to gain information about the effect triggered at the molecular level by nicotine, its neuroimmunomodulatory properties and its impact on the pathogenesis of inflammatory diseases, peripheral blood serum and leukocytes of rat submitted to passive nicotine administration were subjected to proteomic investigation. Serum, polymorphonuclear (PMN) and(More)
Increased cortisol levels in humans are often observed in patients suffering from mood disorders. In this study human fetal brain aggregates were exposed to cortisol at 500 nM for 3 weeks, as an in-vitro model of chronic cortisol exposure. Microarray analysis on extracted mRNA using the Affymetrix U133A platform was then performed. Our results demonstrated(More)
BACKGROUND Inspiratory resistive breathing (IRB) challenges affect respiratory muscle endurance in healthy individuals, which is considered to be an interleukin 6 (IL-6)-dependent mechanism. Whether nonpharmacological thermal therapies promote the endurance of loaded inspiratory muscles in chronic obstructive pulmonary disease (COPD) is unclear. The(More)
