    Do arachnoid cysts grow? (1991)

    Notes: Summary The volumes of intracranial arachnoit cysts were measured in 136 CT scans of 86 patients. Absolute and relative cyst size was calculated. Left hemisphere and middle cranial fossa location prevailed. A slight negative correlation of relative cyst size with age (r=−0.21, NS) disappeared when analysis was restricted to the adult age group (≥20 years). After the sample was divided into two groups according to relative cyst size (cysts less than mean volume vs cysts greater than mean volume), small AC showed no correlation with age, while large AC correlated positively with age (r=0.79,P〈0.05). A subgroup of large AC appears to expand with time, while the majority of small AC remain unchanged.

    Partial purification of sequestered particles of phytochrome from oat (Avenu sativa L.) seedlings (1991)

    Notes: Abstract Sequestered particles of phytochrome (SAPs) were partially purified from red-light-irradiated oat coleoptiles. Phytochrome pelletability was enhanced by using buffers containing 10 mM Mg2+ or high concentrations (0.6–0.8 M) of orthophosphate (Pi). Combining the pelletability of phytochrome in the presence of Mg2+ with that in the presence of 0.6 Pi resulted in a strong enrichment (about 100-fold) of pelletable phytochrome. Antisera were raised against Mg2+-Pi-pellets from darkgrown seedlings. Using these antisera, no evidence was found by Western blotting and immunocytochemistry that SAPs contain major proteins other than phytochrome. The major contamination of these enriched SAP preparations consisted of protein crystals which are probably catalase. The preparations contained methyltransferase and protein-kinase activities which were not associated with SAPs. Phytochrome purified from SAPs served as a substrate for protein-kinase activity but not for the methyltransferase activity. Phytochrome itself did not show any kinase activity.
