    Reduction of root iron in Plantago lanceolata during recovery from Fe deficiency (1996)

    Notes: Changes in root-associated Fe(III) reductase activity and Fe concentration during recovery from temporary iron starvation were investigated in hydroponically grown Plantago lanceolata L. Within two days, interruption of the Fe supply resulted in enhanced rates of reduction by intact plant roots. Transfer of iron deficient plants to a solution containing various amounts of chelated Fe caused a transient increase in reduction activity before the rates declined to a level determined by the amount of Fe added. Repression of root-associated redox activity was independent of the Fe concentration in the preculture. When iron deficient plants were submitted to a supply of Fe localized to a part of the root system (split-root plants), the decrease in reduction rates was much more pronounced in the Fe-deprived portion of the roots than in the Fe-supplied one. No correlation was observed between root Fe concentration and Fe(III) reductase activity. Continued growth of split-root plants in the +Fe/-Fe regime increased the reduction rates of the +Fe-grown portion of the root system over the rates in iron sufficient plants with non-divided roots. The results are discussed in relation to putative factors mediating intra- and interorgan regulation of iron nutrition.

    Pyridine nucleotide pool size changes in iron-deficient Plantago lanceolata roots during reduction of external oxidants (1996)

    Notes: The involvement of pyridine nucleotides in the reduction of extracytoplasmatic electron acceptors by iron-deficient Plantago lanceolata L. roots has been examined by measuring the changes in NAD(P)H and NAD(P)− induced by various external acceptors. Exposure of the plants to FeEDTA, ferricyanide, ferric citrate or hexachloroiri-date resulted in a transient decrease in NADPH and an increase in NAD−. No major differences in this pattern were observed between acceptors which were assumed to be reduced by different enzymes. The application of the membrane-permeable oxidant nitro blue tetrazolium led to similar changes in reduced and oxidized pyridine nucleotides and decreased the reduction of external acceptors. The amino acid analog p-fluorophenylalanine caused a transient decline in both NADPH level and NADPH/ NADP− ratio and a decrease in the ratio of NADH to NAD− without affecting the level of NADH. Exposure of the plants to the translation inhibitor cycloheximide increased both NADH and NADPH concentrations. A comparison of the redox activities and pyridine nucleotide fractions after inhibitor treatment revealed that the constitutive, but not iron stress-induced redox activity correlates with NADPH levels. These results are interpreted as confirming that the redox systems on the root plasma membrane are separately regulated. Possible metabolic reactions during the reduction processes are discussed.

    Notes: Abstract: Let be an exponential polynomial over a field of zero characteristic. Assume that for each pair i,j with i≠j, α i /α j is not a root of unity. Define . We introduce a partition of into subsets (1≤i≤m), which induces a decomposition of f into , so that, for 1≤i≤m, , while for , the number either is transcendental or else is algebraic with not too small a height. Then we show that for all but at most solutions x∈ℤ of f(x)= 0, we have

    Notes: Abstract Lattices Λ, Λ′ are similar if one can be transformed into the other by an angle-preserving linear map. Similarity classes of lattices of rankn may be parametrized by a fundamental domainℱ of the action ofGL n (ℤ) on the generalized upper half-plane ℋ n . Given 1〈n≤m and , letN(D,T) be the number of sublattices of ℋ n which have rankn, similarity class inD, and determinant ≤T. Our most basic result will be thatN(D,T)∼c 1(m, n)μ(D)T m asT→∞ for suitable setsD, where μ is the invariant measure on ℋ n . The casen=2 had been dealt with by Roelcke and by Maass using the theory of modular forms.

    Notes: Abstract A piezo driven tilt mirror was developed and built as one component of an image motion compensation system for a solar telescope. The bandwidth of the mirror with a diameter of 60 mm is about 1 kHz with negligible phase shift between input signal and mirror response up to 900 Hz. The tilt range is 1.6 mrad. Special care was taken to maintain the surface quality of the mirror to better than λ/15 after fixing it to the substrate.

    Chylous cardiac tamponade in acute pancreatitis (1996)

    Notes: Summary A 47-year-old woman with acute necrotizing pancreatitis developed sudden cardiorespiratory arrest and needed resuscitation. A pericardial effusion was found, and 350 ml of a white nontransparent milky fluid was aspirated that contained 1020 mg triglycerides/100 ml. The diagnosis of chylous cardiac tamponade was made. Absence of amylase in the chylous effusion militates against the popular hypothesis that lymphatic transport of exocrine digestive enzymes from the inflamed pancreas produces the frequent intrathoracic serosal effusions in acute pancreatitis. The data of our patient rather suggest that these effusions result from the leakage of pancreatic inflammatory exudates through the diaphragm which, apparently, may even result in the loss of pericardial and adjacent thoracic lymph vessel integrity. Although pericardial tamponade is a rare complication, it should be considered if otherwise unexplained circulatory deterioration occurs in a patient with acute pancreatitis.
