    Notes: [Auszug] The three-dimensional structure of MerA from Bacillus sp. strain RC607 can be clearly divided into three parts: the two N-terminal regions (residues 1-166), the core (167-616), the equivalent of the glutathione reductase structure, and the C-terminal extension (residues 617-631). This partition is ...

    Notes: Abstract. A total of 23 women with stage II breast cancer receiving adjuvant cyclophosphamide, methotrexate and 5-fluorouracil had detailed pharmacokinetic monitoring performed on the first and third courses of therapy. The area under the concentration time curve (AUC) of each of these three drugs varied by a factor of 3–4 among patients. No systematic change in pharmacokinetics between the first and third courses was seen for cyclophosphamide, methotrexate or 5-fluorouracil, and the mean AUC for each of the three drugs did not change. However, significant intrapatient variability in drug pharmacokinetics was observed for all three drugs such that the AUC, clearance and half-life in an individual on the third course could not be reliably predicted from data generated on the first course. On the basis of these results, cyclophosphamide, methotrexate, and 5-fluorouracil pharmacokinetic data from one treatment would not be useful information from which the doses for subsequent courses could be determined.

    Notes: Summary In the 3-, 33- and 66-day-old chicken, two muscles, the oxidative slow tonic anterior latissimus dorsi and the glycolytic fast twitch posterior latissimus dorsi were compared by the measurement of muscle fibre diameter and the fraction of total muscle tissue nuclei which were either myonuclei or satellite cell nuclei. Between 3 and 33 days there was a period of rapid growth (more marked in the posterior latissimus dorsi) which coincided with a sharp fall in numerical density of myonuclei and satellite cell nuclei (number per cubic millimetre muscle tissue). The fraction of all nuclei which were satellite cell nuclei declined steadily. The higher levels of myonuclei and satellite cell nuclei in the anterior latissimus dorsi were thought to be a reflection of its oxidative metabolism and the presence of multiple endplates. The volume of sarcoplasm occupied by single myonuclei in anterior and posterior latissimus dorsi muscles was shown to be considerably greater than that occupied by nuclei in other cell systems.
