Cephalosporin P1 and helvolic acid

Antimicrobial activity and mechanisms of resistance to cephalosporin P1, an antibiotic related to fusidic acid.

The antimicrobial properties of cephalosporin P1, an antibiotic structurally related to fusidic acid, were examined. Cephalosporin P1 exhibited potent activity against methicillin-sensitive Staphylococcus aureus, methicillin-resistant S. aureus and vancomycin-intermediate S. aureus. Mutants of S. aureus resistant to cephalosporin P1 arose with a frequency of 1.6 x 10(-6) for selections at 4 x M...

P1: Negative Television and Memory

According to reports about 30-thousand people spent watching television had the impact on their memory and recall that the results showed no differences between men and women. The people who watched less than an hour a day did better at every memory function. As these contributors watched negative political ads, physiological responses indicated that their body was reflexively preparing to move...

The amino acid sequence of human sperm protamine P1.

Human sperm protamines have been extracted from spermatozoa pooled from several donors, converted to their S-pyridylethylated derivatives and resolved into two major components, P1 and P2, by Bio-Rex 70 chromatography. Protamine P1 was further purified by Bio-Gel P-10 chromatography and sequenced directly on a gas phase protein sequencer for 43 residues. To complete the sequence, P1 was cleaved...

Isolation of Phthalic Acid Degrading Pseudomonas Sp. P1 from Soil

Phthalates are common plasticizers used in pPVC (plasticized polyvinyl chloride) products. Phthalates are commonly found in the child rearing products (for teething, toys etc.), blood bags, dialysis tubing, paints, lacquers, cosmetics, coatings of capsules etc. The present study was conducted to explore the potential of new microbial strains for the biodegradation and biotransformation of phtha...
