Multimediale Unterrichtssoftware ‐ Beispiel: Stickstoff im Ökosystem
Authors: Gulinska Hanna , Burewicz Andrzej
Published: May 2007

DIE NUTZUNG DES COMPUTERS beschränkte sich in den 80er Jahren hauptsächlich auf Textverarbeitung, Tabellenkalkulation, Datenbanken und Grafikprogramme. Die 90er Jahre werden entscheidend durch die Entwicklung von Multimedia‐Systemen geprägt. Wesentliches Kriterium für „Multimedia”︁ ist, daß die Vorteile des Computers ‐ insbesondere die Interaktionsmöglichkeiten ‐ mit denen audiovisueller Medien verknüpft werden. Auf diese Weise können z.B. interaktive Lernprogramme mit Videosequenzen und qualitativ hochwertiger Sprach‐/Klangausgabe erstellt werden [1]. Multimediale Programme werden zukünftig nicht nur in den Schulen, sondern auch in der Wirtschaft, der Werbung, dem Fernsehen und der Wissenschaft eine breite Anwendung finden.
Differential expression of Sox2 and Sox3 in neuronal and sensory progenitors of the developing inner ear of the chick
Authors: Neves Joana , Kamaid Andrés , Alsina Berta , Giraldez Fernando
Published: May 2007

The generation of the mechanosensory elements of the inner ear during development proceeds in a precise temporal and spatial pattern. First, neurosensory precursors form sensory neurons. Then, prosensory patches emerge and give rise to hair and supporting cells. Hair cells are innervated by cochleovestibular neurons that convey sound and balance information to the brain. SOX2 is an HMG transcription factor characteristic of the stem‐cell genetic network responsible for progenitor self‐renewal and commitment, and its loss of function generates defects in ear sensory epithelia. The present study shows that SOX2 protein is expressed in a spatially and temporally restricted manner throughout development of the chick inner ear. SOX2 is first expressed in the neurogenic region that gives rise to sensory neurons. SOX2 is then restricted to the prosensory patches in E4 and E5 embryos, as revealed by double and parallel labelling with SOX2 and Tuj1, MyoVIIa, or Islet1. Proliferating cell nuclear antigen labelling showed that SOX2 is expressed in proliferating cells during those stages. By E5, SOX2 is also expressed in the Schwann cells of the cochleovestibular ganglion, but not in the otic neurons. At E8 and E17, beyond stages of sensory cell specification, SOX2 is transiently expressed in hair cells, but its level remains high in supporting cells. SOX3 is concomitantly expressed with SOX2 in the neurogenic domain of the otic cup, but not in prosensory patches. Our data are consistent with a role for SOX2 in specifying a population of otic progenitors committed to a neural fate, giving rise to neurons and hair cells. J. Comp.

Commutation relations for Schramm‐Loewner evolutions
Authors: Dubédat Julien
Published: May 2007

Schramm‐Loewner evolutions (SLEs) describe a one‐parameter family of growth processes in the plane that have particular conformal invariance properties. For instance, SLE can define simple random curves in a simply connected domain. In this paper we are interested in questions pertaining to the definition of several SLEs in a domain (i.e., several random curves). In particular, we derive infinitesimal commutation conditions, discuss some elementary solutions, study integrability conditions following from commutation, and show how to lift these infinitesimal relations to global relations in simple cases. The situation in multiply connected domains is also discussed. © 2007 Wiley Periodicals, Inc.
Self‐monitoring of blood glucose in type‐2 diabetes: what is the evidence?
Authors: McGeoch Grace , Derry Sheena , Moore R. Andrew
Published: May 2007

Background

There is a controversy about self‐monitoring of blood glucose (SMBG) in patients with type 2 diabetes who are not using insulin. Randomized trials are limited in duration, size, and validity.

Methods

Systematic search for randomized trials and observational studies published since 1990. For inclusion studies had to report on SMBG in type 2 diabetes managed with oral hypoglycaemic agents and/or diet alone, HbA1c or clinical outcome, have at least 50 patients and be of at least 6 months' duration.

Results

Three randomized trials with 1000 patients were included, though all had interventions differing in the amount of education on SMBG, and in the population studied. The two larger studies had statistically significantly lower HbA1c levels with SMBG. Thirteen observational studies had information on over 60 000 patients. Smaller studies had lower initial HbA1c and showed no association between SMBG and laboratory or clinical improvement. Larger studies tended to have higher initial HbA1c and did show an association between SMBG and laboratory or clinical improvement. Overall, improvement in glycaemic control with SMBG tended to be seen in studies with initial HbA1c above 8%.

Conclusions

It is likely that SMBG is beneficial in some circumstances, for example as an educational tool, for patients with type 2 diabetes not using insulin who have poor glycaemic control. More information is needed at the level of the individual patient, rather than group means, and about timing and frequency of monitoring, response to those results, what constitutes effective patient education, and long‐term clinical outcomes.

Cognitive feelings and metacognitive judgments
Authors: Clore Gerald L. , Parrott W Gerrod
Published: May 2007

In two studies, subjects read and rated how well they understood a poem. Beforehand, however, they had participated under hypnosis in an exercise designed to induce feelings of being uncertain about something. For half of the subjects hypnosis was made salient as a cause for the feelings; for the other half the feelings remained unexplained. The results showed that when left unexplained, the feelings of uncertainty were interpreted by subjects as indications that they did not understand the poem. When attributed to the hypnosis, however, the feelings had no effect on ratings of comprehension. In one experiment, subjects were also studied who were not susceptible to hypnosis, and who, therefore, did not feel uncertain in the first place. The results suggest that just as positive and negative affective feelings serve as information for making evaluative judgments, feelings of certainty and uncertainty serve as information for making cognitive judgments (t. e. judgments of knowing).
Caffeic Acid‐Modified Glassy Carbon Electrode for the Simultaneous Determination of Epinephrine and Dopamine
Authors: Li Nian Bing , Ren Wang , Luo Hong Qun
Published: May 2007

A stable electroactive thin film of poly(caffeic acid) has been deposited on the surface of a glassy carbon electrode by potentiostatic technique in an aqueous solution containing caffeic acid. The electrochemical behaviors of epinephrine (EP), dopamine (DA) and their mixture have been studied. The oxidation peaks of EP and DA at the poly(caffeic acid) modified glassy carbon electrode appeared at the same potential, but the anodic peak currents of the mixture of DA and EP were almost equal to the sum of individual anodic peak currents of EP and DA, whereas the cathodic peak current only related to the concentration of DA under appropriate condition. Base on these, the simultaneous voltammetric measurement of EP and DA at the poly(caffeic acid) film modified electrode has been developed. Ascorbic acid (AA) had no interference with the simultaneous determination of EP and DA under the same condition because the oxidative peak potential of AA was less than those of DA and EP. The modified electrode has been satisfactorily used for the simultaneous determination of EP and DA in real samples.
Amperometric Ethanol Biosensor Based on Carbon Nanotubes Dispersed in Sol–Gel‐Derived Titania–Nafion Composite Film
Authors: Choi Han Nim , Lyu Young‐Ku , Han Jee Hoon , Lee Won‐Yong
Published: May 2007

Composite solution of sol–gel‐derived titania and perfluorosulfonated ionomer (Nafion) was used as a solubilizing agent for multiwalled carbon nanotubes (CNT) as well as an encapsulation matrix for alcohol dehydrogenase (ADH) for the fabrication of a highly sensitive and stable amperometric ethanol biosensor. ADH was immobilized within a thin film of CNT–titania–Nafion composite film coated on a glassy carbon electrode. Because of the mesoporous nature of the CNT–titania–Nafion composite film, the present biosensor exhibited remarkably fast response time within 2 s. The presence of CNT in the composite film increases not only the sensitivity of the ethanol biosensor but also the long‐term stability of the biosensor. The present biosensor responds linearly to ethanol in the wide concentration ranges from 1.0×10−5 M to 3.0×10−3 M with the sensitivity of 51.6 mA M−1cm−2. The present biosensor showed good long‐term stability with 75% of its activity retained after 4 weeks of storage in 50 mM phosphate buffer at pH 7.0.

Circadian control of physiology is mediated by local, tissue-based clocks, synchronized to each other and to solar time by signals from the suprachiasmatic nuclei (SCN), the master oscillator in the hypothalamus. These local clocks coordinate the transcription of key pathways to establish tissue-specific daily metabolic programs. How local transcriptomes are synchronized across the organism and their relative contribution to circadian output remain unclear. In the present study we showed that glucocorticoids alone are able to synchronize expression of about 60% of the circadian transcriptome. We propose that synchronization occurs directly by the action of glucocorticoids on a diverse range of downstream targets and indirectly by regulating the core clock genes

We have demonstrated that by orchestrating transcriptional cascades, glucocorticoids are able to direct synchronization of a diverse range of functionally important circadian genes. (Hepatology 2007;45:1478–1488.)
4-phenylbutyrate enhances the cell surface expression and the transport capacity of wild-type and mutated bile salt export pumps
Authors: Hayashi Hisamitsu , Sugiyama Yuichi
Published: May 2007

Progressive familial intrahepatic cholestasis type 2 (PFIC2) is caused by a mutation in the bile salt export pump (BSEP/ABCB11) gene. We previously reported that E297G and D482G BSEP, which are frequently found mutations in European patients, result in impaired membrane trafficking, whereas both mutants retain their transport function. The dysfunctional localization is probably attributable to the retention of BSEP in endoplasmic reticulum (ER) followed by proteasomal degradation. Because sodium 4-phenylbutyrate (4PBA) has been shown to restore the reduced cell surface expression of mutated plasma membrane proteins, in the current study, we investigated the effect of 4PBA treatment on E297G and D482G BSEP. Transcellular transport and cell surface biotinylation studies using Madin-Darby canine kidney (MDCK) II cells demonstrated that 4PBA treatment increased functional cell surface expression of wild-type (WT), E297G, and D482G BSEP. The prolonged half-life of cell surface–resident BSEP with 4PBA treatment was responsible for this result. Moreover, treatment of Sprague-Dawley rats with 4PBA resulted in an increase in BSEP expression at the canalicular membrane, which was accompanied by an increase in the biliary excretion of [3H]taurocholic acid (TC).

Conclusion:

4PBA treatment with a clinically achievable concentration enhances the cell surface expression and the transport capacity of WT, E297G, and D482G BSEP in MDCK II cells, and also induces functional BSEP expression at the canalicular membrane and bile acid transport via canalicular membrane

in vivo

. 4PBA is a potential pharmacological agent for treating not only PFIC2 patients with E297G and D482G mutations but also other cholestatic patients, in whom the BSEP expression at the canalicular membrane is reduced. (Hepatology 2007;45:1506–1516.)

Some studies suggest that the histaminergic system plays an important role in learning and memory. However, the results seem to be controversial in many behavioral tasks. In the present study, we used HDC knockout (HDC‐KO) mice to investigate the effects of long‐term histamine deficiency on learning and memory in contextual fear conditioning. We found that HDC‐KO mice exhibited improved contextual fear from 1 day after training and this lasted for at least 14 days when compared with the wild‐type (WT) controls. Cued fear was also improved 2 days after training in HDC‐KO mice. Moreover, injection of histamine (intracerebroventricularly, 10 μg/mouse) immediately after training reversed the improvement in contextual fear conditioning when tested 1 day after training. Electrophysiological data showed that hippocampal CA1 long‐term potentiation (LTP) in HDC‐KO mice was much greater than that in WT mice, and paired‐pulse facilitation decreased 2 h after LTP induction in HDC‐KO mice. In contrast, HDC‐KO mice showed smaller LTP than did WT mice 1 day after training. Hippocampal glutamate levels significantly increased in HDC‐KO mice 1 and 4 days after training. The results indicated that histamine deficiency may improve consolidation of contextual fear conditioning. This improvement may be due to the increased hippocampal CA1 LTP, and presynaptic glutamate release. The relationship between behavior and synaptic plasticity provides support for the involvement of activity‐dependent LTP in learning and memory. © 2007 Wiley‐Liss, Inc.
Fracture modes under uniaxial compression in hydroxyapatite scaffolds fabricated by robocasting
Authors: Miranda Pedro , Pajares Antonia , Saiz Eduardo , Tomsia Antoni P. , Guiberteau Fernando
Published: May 2007

The fracture modes of hydroxyapatite (HA) scaffolds fabricated by direct‐write assembly (robocasting) are analyzed in this work. Concentrated HA inks with suitable viscoelastic properties were developed to enable the fabrication of prototype structures consisting of a 3‐D square mesh of interpenetrating rods. The fracture behavior of these model scaffolds under compressive stresses is determined from in situ uniaxial tests performed in two different directions: perpendicular to the rods and along one of the rod directions. The results are analyzed in terms of the stress field calculated by finite element modeling (FEM). This analysis provides valuable insight into the mechanical behavior of scaffolds for bone tissue engineering applications fabricated by robocasting. © 2007 Wiley Periodicals, Inc.
