Mutations in RAS2, CYR1, and SCH9 extend the chronological life span in Saccharomyces cerevisiae by activating stress-resistance transcription factors and mitochondrial superoxide dismutase (Sod2). Here we show that mutations in CYR1 and SCH9 also extend the replicative life span of individual yeast mother cells. However, the triple deletion of stress-resistance genes MSN2/MSN4 and RIM15, which...

To prepare niosomes containing rifampicin were prepared using various nonionic surfactants of sorbitan ester class and cholesterol in 50:60 (1:1.2) percent mol fraction ratios for sustain release. To improve the dissolution rate of noisome are prepare handshaking method using Surfactants and cholesterol (150 μmol) in 50:60 (1:1.2) percent mol fraction ratio. The percent of drug estimated to be ...

Neuropsychological reports and activation studies by means of positron emission tomography and functional magnetic resonance imaging have suggested that the neural correlates of phonological short-term memory are located in the left hemisphere, with Brodmann's area (BA) 40 being responsible for short-term storage, and BA 44 for articulatory rehearsal. However, a careful review of the literature...
