    Notizen: Oyster mushrooms, Pleurotus sajor-caju, were grown on chopped corn stover substrate with increasing amounts of cracked corn supplementation and were harvested at immature and mature stages of growth. Descriptive terms for mushroom color, texture, and flavor were generated and used to determine the impact of cracked corn supplementation on the sensory attributes of fresh and stored (5C for 48h) immature mushrooms and of fresh mature oyster mushrooms. Results indicated that supplementation with cracked corn significantly (P 〈 0.05) affected the texture attributes, i.e., tough, rubbery, and fibrous of the oyster mushroom. When factor analysis (FA) was applied to the descriptor data, three factors were identified in the immature fresh and immature stored oyster mushrooms data which explained 86 and 82%, respectively, of the variation. FA of data from the mature oyster mushrooms identified 3 factors which explained 89% of the data variation.

    Notizen: Summary Goal. To assess the morbidity and mortality of meningioma surgery in patients over age 65 and compare our results with matched controls and with the present literature on meningioma surgery in the elderly. Methods. An evaluation of 114 patients undergoing meningioma resection divided into two groups: 57 patients aged 65–87, and a control group of 57 patients aged 25–64 matched by ASA status and tumor site. Operative complications, 30-day mortality, and pre- and postoperative neurologic status were assessed with follow up one to three months. Results. Complication rates in the two groups were similar and were low. Four out of fifty-seven elderly patients (7.0%) had a surgical complication compared with five younger patients (8.8%) Excluding asymptomatic DVT detected by screening, three elderly patients had medical complications (5.2%) compared with two controls (3.5%).  The vast majority of patients—93% of the elderly group and 89.4% in the controls—experienced either improvement or no change in neurologic status at followup one to three months after surgery.  There was one death among elderly patients within thirty days for a mortality rate of 1.8% compared with no mortality in the case control group. The elderly patient who died was an 80-year old man who died of pneumonia in a rehabilitation hospital three weeks after surgery.  Our study group of 57 patients was compared by tumor site and preoperative general health status to other series in the literature. In a review from the literature of 417 patients over age 65 who underwent meningioma surgery, the average 30-day mortality was 16%. The complication rate averaged 39%. Discussion. Our lower morbidity and mortality rates after meningioma surgery in the elderly may be a result of patient selection, surgical technique, or excellent pre- and post-operative care by the resident staff, anesthesiologists, and nurses. It suggests, however, that elderly patients can have meningioma surgery safely.

    WAPK, a Ser/Thr protein kinase gene of Nicotiana tabacum, is uniquely regulated by wounding, abscisic acid and methyl jasmonate (1998)

    Notizen: Abstract A cDNA encoding a protein kinase, which may be involved in the wound signal transduction pathway, was isolated from Nicotiana tabacum. The cDNA, named WAPK, is 1227 bp in length and contains an ORF of 1017 bp. The ORF encodes a polypeptide of 339 amino acids, with a calculated molecular mass of 38234 Da. Analysis of the deduced amino acid sequence shows that the N-terminal region of WAPK contains a catalytic region composed of eleven subdomains which are typically found in Ser/Thr protein kinases. This region shows 78–84% sequence identity with similar regions of abscisic acid (ABA)-induced and external-stimuli-responsive protein kinases. However, the C-terminal region of WAPK shows little homology with similar regions of Ser/Thr protein kinases, except for a 16-amino acid stretch near the end of the catalytic domain. Kinase assays using a WAPK fusion protein expressed in E. coli revealed that WAPK autophosphorylates on serine residue(s). The WAPK gene is predominantly expressed in flowers, moderately in roots, and poorly in leaves. Transcripts were not detected in stems. The WAPK gene was induced by wounding (within 1.5 h), by abscisic acid (within 0.5 h), and by methyl jasmonate (within 2 h). The induction pattern of WAPK mRNA upon wounding was not affected by treatment with diethyldithiocarbamic acid, a reagent which inhibits jasmonic acid biosynthesis. These results suggest that the WAPK gene is regulated by ABA in the wound signal transduction pathway.
