    Notes: Calcium salts of high-oleic sunflower oil (〉 86% oleic acid) were prepared and fed at 0% and 7.5% of diet dry matter weight to 8 Holstein cows in early- to mid-lactation in a cross-over experimental design. Oleic acid content of milk fat increased from 26% to over 40% and cholesterol-raising saturates were reduced from 41% to 33%. Latin American white cheese, queso blanco, was produced from modified and normal milk. No differences in firmness were found between cheeses using penetration-compression testing with an Instron machine. Sensory difference tests indicated no significant differences between cheeses. Latin American white cheeses made with high oleic milk are similar to traditional cheese.

    Notes: Patients with renal disease often develop accelerated atherosclerosis resulting in more frequent cardiovascular complications compared to the general population. It has been suggested that peroxidation of low density lipoprotein (LDL) contributes to the pathogenesis of atherosclerosis and glomerulosclerosis. The present study aimed to investigate the phosphatidylcholine hydroperoxide (PC-OOH) content of LDL in patients with chronic renal failure (CRF) and patients on haemodialysis (HD). Plasma was obtained from healthy volunteers (n = 20; age 45.8 ± 16.9 years), CRF patients (n = 23; age 49.4 ± 18.1 years) and patients on HD (n = 19; age 59.1 ± 10.3 years). The lipid profile was studied in all patients. The LDL was isolated by sequential ultracentrifugation. The oxidized PC-OOH content of LDL was measured by high performance liquid chromatography with chemiluminescence detection (HPLC-CL). Compared to the controls, patients with proteinuria had significantly higher plasma concentrations for total cholesterol, LDL-cholesterol and apoB, whereas patients on HD had significantly higher levels of triglycerides and reduced HDL and apoA1 plasma concentrations. Significantly elevated levels of PC-OOH were found in HD patients (22.56 ± 13.40 pmol/mg LDL-cholesterol) and CRF patients (13.12 ± 15.15 pmol/mg LDL-cholesterol) compared to the controls (0.56 ± 0.38 pmol/mg LDL-cholesterol; P 〈 0.001). In HD patients the PC-OOH concentration was higher compared to CRF patients (P 〈 0.05). It was concluded that lipid hydroperoxides increase in renal disease and in patients on HD. These elevated lipid hydroperoxides may contribute to the increased risk for atherosclerosis in these patients.

    Description / Table of Contents: Zusammenfassung 3-M, ein Oxidationsprodukt der Indol-3-essigsäure, hemmt den Transport von Auxinen durch Koleoptilen (Hager und Schmidt, 1968); seine Wirkungsweise wird untersucht. Werden 1 mm lange Segmente von Maiskoleoptilen mit IES-2-14C inkubiert, so ist bei Anwesenheit von 3-M eine jeweils höhere Konzentration von markiertem Wuchsstoff im Gewebe festzustellen (“apparente Aufnahme”). Da aber der Influx von IES-2-14C in die Segmente (“reelle Aufnahme”) durch Zugabe von 3-M in den ersten 30 min überhaupt nicht verändert wird, muß die Auxinakkumulation eine andere Ursache haben: Die aktive Abgabe, d.h. die Sekretion von IES-2-14C aus 1 mm langen Koleoptilsegmenten in die Außenlösung, erfährt durch 3-M eine sehr starke Erniedrigung. Sie muß als Ursache des verringerten polaren Wuchsstofftransports angesehen werden. 3-M wirkt also ähnlich wie der künstliche Transporthemmstoff TIBA. Der polare Transport von NES-1-14C durch Koleoptilsegmente wird wie der des Auxins bei Zugabe von 3-M, von TIBA und durch Belichtung der Koleoptilen gehemmt. Aus den obigen Befunden, ferner weil 3-M wichtige Stoffwechsel-prozesse, wie z.B. die Atmung, nicht beeinflußt, andererseits eine Bindung mit SH-Gruppen-haltigen Substanzen (Cystein) eingeht, wird auf eine direkte Beeinflussung des Auxintransportsystems durch 3-M geschlossen. Es wird angenommen, daß die wuchsstoffsezernierenden Areale (“Permeasen”), welche sich in den äußeren Plasmagrenzschichten und hauptsächlich im basalen Bereich der Zelle befinden oder dort aktiv tätig sein sollen (polarer Transport!), durch 3-M teilweise blockiert werden können (möglicherweise durch eine Adduktbildung des 3-M mit SH-Gruppen der “Permeasen”). Als eine mögliche Ursache der Wuchsstoffquerverschiebung beim Phototropismus wird die asymmetrische photooxidative Bildung von 3-M in jeder einzelnen, seitlich belichteten Zelle und eine daraus resultierende laterale Wuchsstoffabgabe diskutiert.
    Notes: Summary 3-M, an oxidation product of IAA, inhibits the transport of auxin through coleoptiles (Hager and Schmidt, 1968); the mode of action of this inhibition has been investigated. During incubation of 1 mm long sections of corn coleoptiles with IAA-2-14C, the presence of 3-M increases the concentrations of labeled auxin in the tissue. Since the influx of IAA-2-14C into the sections is not at all changed during the first 30 minutes, the accumulation of auxin has to be due to some other mechanism besides uptake. The active exit step, that is the secretion of IAA-2-14C out of 1 mm long coleoptile sections into the surrounding solution, is strongly impaired by 3-M. It is this phenomenon which has to be regarded as the cause of the reduced polar transport of auxin. The polar transport of NAA-1-14C through coleoptile sections, just like that of IAA, is inhibited by addition of 3-M, or TIBA or by illumination of the coleoptiles. From the results mentioned above and from the fact that 3-M does not influence important metabolic processes like respiration but on the other hand is able to react with compounds containing SH-groups (like cystein), it is concluded that the transport of auxin is directly influenced by 3-M. It is suggested that systems secreting auxin (“permeases”) in the outer border layers of the plasma, mainly in the basal parts of the cell (polar transport!) could be partly blocked by 3-M (possibly by the formation of an adduct with SH-groups of the “permeases”). The asymmetric photooxidative formation of 3-M in each single cell illuminated laterally and the subsequent lateral secretion of auxin may be the reason for the transversal shift of auxin during phototropism.

    Notes: Summary Short illumination of excised coleoptiles (with or without apex) inhibits the subsequent transport of IAA-2-14C in these sections during darkness. To a certain extent the inhibition is dependent both on the light intensity and on the duration of illumination. Only the blue region of the visible spectrum is effective. The light induced inhibition is due to a decrease of the quantity of IAA transported; on the other hand, the velocity of transport remains unchanged. The inhibition of auxin transport can be observed only if coleoptiles contain endogenous or fed auxin during the preceding illumination period. Besides illumination inhibition of auxin transport can also be brought about by incubation of coleoptile sections with a previously illuminated IAA/FMN solution. Auxin transformed by peroxidase operates in the same way. The different oxidation products of IAA in the solutions used were identified: The only product which inhibits elongation growth and auxin transport was 3-M. The conversion of IAA to 3-M is accomplished by crude cell-free extracts from corn coleoptiles. An increased formation of labeled 3-M from IAA-2-14C during illumination of coleoptiles could be demonstrated. Since 3-M is not actively transported in coleoptiles, it must be assumed that 3-M functions as an inhibitor of auxin transport only at its site of formation. It is concluded that the phototropic curvature of coleoptiles and stems is triggered by the photooxidative formation of 3-M from IAA in the side exposed to light. The flow of growth substances will be partly blocked by 3-M in this side and can be directed to the shaded side. On the strength of these findings some phenomena of phototropism (transmission of stimulus, “mneme”, quantum yield) can easily be explained.

    Notes: Abstract The Wilms' tumor gene (WT1) encodes a transcriptional regulator involved in growth and differentiation of various tissue types. A continuous over-expression of WT1 was found in leukemic blasts, thus suggesting an oncogenic function. Solid cancer entities have also been described as expressing WT1. We systematically analyzed WT1 expression in small-cell and non-small-cell lung cancer, colon cancer and glioblastoma patients and in the respective tumor cell lines. Using reverse transcription/polymerase chain reaction, we found WT1 expression in glioblastoma (5 of 8), lung (5 of 11), and colon cancer (5 of 15) cell lines. While WT1 was expressed in only 1 of 12 lung cancer and 1 of 5 glioblastoma specimens, it was not detected in colon cancer or macroscopically tumor-free colon and lung tissue. In addition, HT29 colon cancer cells showed a loss of WT1 expression when grown to confluence or induced to differentiate by sodium butyrate. From this evidence, testing for WT1 expression is not clinically relevant for colon cancer, lung cancer, or glioblastoma patients. WT1 expression in cancer cell lines can probably be attributed to optimized in vitro growth conditions.

    Notes: Die Radioonkologie nimmt in der kurativen und palliativen Behandlung onkologischer Patienten einen wichtigen Stellenwert ein. Moderne Therapie- und Fraktionierungskonzepte haben zu einer wesentlichen Verbesserung der Heilungschancen beigetragen. Das Ausmaß der subjektiv beeinträchtigenden akuten und späten Nebenwirkungen, insbesondere der Haut- und Schleimhaut, bestimmen wesentlich die Akzeptanz der Behandlung durch die Patienten. Durch therapiebegleitende pflegerische Maßnahmen ist eine Linderung der Beschwerdesymptomatik und teils auch eine Verringerung des Ausprägungsgrades später Reaktionen möglich. Hierfür stehen verschiedene Konzepte ähnlicher Wertigkeit zur Verfügung. Eine Empfehlung zu pflegerischen Maßnahmen in der Radioonkologie wird exemplarisch im Tübinger Pflegekonzept gegeben.
