Maximum concentrations of microsomal cytochrome P-450 are present in 3-4 day-old mung beans (Phaseolus aureus). On illumination of dark-grown seedlings, cytochrome P-450 and later cytochrome P-450 undergo a rapid decrease in concentration in vivo, with an apparent half-time of about 6 h. Conversely light-grown seedlings, transferred to darkness, show a slow accumulation of cytochrome P-450, dou...

The European Working Time Directive, implemented by the European Union (EU) in 1993, was adopted in the medical profession to improve patient safety as well as the working lives of doctors. The Directive reduced the average amount of hours trainee doctors worked to 48 hours per week. However, its adoption has varied throughout the EU. Its potential effect on both the quality and total amount of...

AIM To determine how long it takes neonatal blood cultures to become positive. METHODS Data were collected retrospectively on 451 positive blood cultures from babies on a tertiary neonatal unit between January 1997 and December 1998. During the study period, the laboratory used the BacT/Alert microbial detection system. RESULTS Complete information was available on 416 blood cultures. Twelv...

We expressed mouse cytochrome P1-450 and P3-450 using recombinant vaccinia virus gene expression system in HeLa cells that were devoid of significant basal levels of P-450. HeLa cells were infected with the recombinant vaccinia virus containing either mouse cytochrome P1-450 or P3-450 cDNA, and the cell lysates were analyzed for the kinetics of P-450 enzyme activity and protein expression at th...

background: the disposal the wastewater sugar extraction to the rivers and environment cause contamination and is considered as a threat to the marine life and the environment. thus, treatment of the wastewater is necessary. investigating the reduction of the pollution load of cane industry with anaerobic sequencing batch biofilm reactor (asbbr) in the laboratory scale is the purpose of this st...
