Published: July 2005

Der zweite Hauptsatz der Thermodynamik ist von elementarer Bedeutung für das Verständnis der Chemie. Denn erst mit der Kenntnis des zweiten Hauptsatzes wird deutlich, warum einige chemische Reaktionen freiwillig ablaufen und andere wiederum nur dann ablaufen, wenn dem Reaktionssystem stetig Energie hinzugefügt wird. Die Frage nach der Begründung der Freiwilligkeit der Reaktionen kann den Schülern erst mit dem zweiten Hauptsatz der Thermodynamik gegeben werden.
Eis – Gefrieren von Wasser im Schnelldurchlauf
Authors: de Vries Tönjes , Paschmann Antje
Published: July 2005

An heißen Sommertagen lieben wir es als erfrischenden Zusatz zu Cola und Säften; im Winter benutzen wir es zum Skifahren, Schlittschuhlaufen und auch für die Schneeballschlacht. Vor allem Kleinkinder sind bei ihren ersten Begegnungen von diesem Stoff fasziniert, da er, in den Händen gehalten, im Gegensatz zu vielen anderen greifbaren Gegenständen in wenigen Minuten „zerstört”︁ wird. Wovon ist hier die Rede? Natürlich von Eis, jeder von uns kennt es.

Während uns das Ergebnis des Gefrierprozesses von Wasser sehr vertraut ist, können wir die Eisbildung selbst meist nicht beobachten. Das liegt zum einen daran, dass der Gefrierprozess häufig im Verborgenen abläuft (z. B. in der Gefriertruhe), zum anderen daran, dass die Eisbildung bei geringen Minusgraden in der Natur nur unmerklich langsam vonstatten geht.

Im Folgenden wird ein einfaches Experiment vorgestellt, mit dem der Gefrierprozess von Wasser in eindrucksvoller Geschwindigkeit „live”︁ demonstriert werden kann. Gleichzeitig ist dabei die mit der Eisbildung einhergehende die Volumenausdehnung zu beobachten. Außerdem wird in einem Modellexperiment gezeigt, dass man an kalten Wintertagen besser nicht mit nasser Haut Metallgegenstände berührt.
Spatio‐temporal regulation and cleavage by matrix metalloproteinase stromelysin‐3 implicate a role for laminin receptor in intestinal remodeling during Xenopus laevis metamorphosis
Authors: Amano Tosikazu , Fu Liezhen , Marshak Anastasia , Kwak Olivia , Shi Yun‐Bo
Published: July 2005

The 37‐kd laminin receptor precursor (LR) was first identified as a 67‐kd protein that binds laminin with high affinity. We have recently isolated the Xenopus laevis LR as an in vitro substrate of matrix metalloproteinase stromelysin‐3 (ST3), which is highly upregulated during intestinal metamorphosis in Xenopus laevis. Here, we show that LR is expressed in the intestinal epithelium of premetamorphic tadpoles. During intestinal metamorphosis, LR is downregulated in the apoptotic epithelium and concurrently upregulated in the connective tissue but with little expression in the developing adult epithelium. Toward the end of metamorphosis, as adult epithelial cells differentiate, they begin to express LR. Furthermore, LR is cleaved during intestinal remodeling when ST3 is highly expressed or in premetamorphic intestine of transgenic tadpoles overexpressing ST3. These results suggest that LR plays a role in cell fate determination and tissue morphogenesis, in part through its cleavage by ST3. Interestingly, high levels of LR are known to be expressed in tumor cells, which are often surrounded by fibroblasts expressing ST3, suggesting that LR cleavage by ST3 plays a role in both physiological and pathological processes.

Expression of voltage sensitive calcium channel (VSCC) L‐type Cav1.2 (α1C) and T‐type Cav3.2 (α1H) subunits during mouse bone development
Authors: Shao Ying , Alicknavitch Michael , Farach‐Carson Mary C.
Published: July 2005

Voltage‐sensitive calcium channels (VSCCs) are key regulators of osteoblast plasma membrane Ca2+ permeability and are under control of calcitropic hormones. Subtype specific antibodies were used to probe L‐type Cav1.2 (α1C) and T‐type Cav3.2 (α1H) subunit expression during mouse skeletal development. Commencing from E14.5 and continuing through skeletal maturity, immunoreactivity of Cav1.2 (α1C) subunits was evident in regions of rapid long bone growth, including the perichondrium, periosteum, chondro‐osseous junction and trabecular bones. Cav3.2 (α1H) subunits appeared simultaneously and followed a similar distribution pattern. Both subunits were observed in osteoblasts and chondrocytes under high magnification. Interestingly, Cav3.2 (α1H) subunits were present, but Cav1.2 (α1C) subunits were absent from osteocytes. Western Blot and immunohistochemical assessment of in vitro cell culture models of osteogenesis and chondrogenesis confirmed the in vivo observations. We conclude that both L‐type Cav1.2 (α1C) and T‐type Cav3.2 (α1H) VSCCs are dynamically regulated in bones and cartilages during endochondral bone development.

Xenopus hairy2b specifies anterior prechordal mesoderm identity within Spemann's organizer
Authors: Yamaguti Mami , Cho Ken W.Y. , Hashimoto Chikara
Published: July 2005

Spemann's organizer is a region of the gastrula stage embryo that contains future anterior endodermal and dorsal mesodermal tissues. During gastrulation, the dorsal mesoderm is divided into the prechordal mesoderm and the chordamesoderm. However, little is known regarding how this division is established. We analyzed the role of the anterior prechordal mesoderm‐specific gene Xhairy2b in the regionalization of the organizer. We found that mesoderm‐inducing transforming growth factor‐β signaling induced Xhairy2b expression. On the other hand, the ectopic expression of Xhairy2b induced the expression of organizer‐specific genes and resulted in the formation of a secondary dorsal axis lacking head and notochord structures. We also showed that Xhairy2b down‐regulated the expression of ventral mesodermal, anterior endodermal, and chordamesodermal genes. In Xhairy2b‐depleted embryos, defects in the specification of anterior prechordal mesoderm identity were observed as the border between the prechordal mesoderm and the chordamesoderm was anteriorly shifted. These results suggest that Xhairy2b establishes the identity of the anterior prechordal mesoderm within Spemann's organizer by inhibiting the formation of neighboring tissues.

Benthic Diatoms as Indicators of Stream Sediment Concentrationin Hong Kong
Authors: Dickman Michael David , Peart Mervyn Richard , Wai‐Shu Yim Wyss
Published: July 2005

Diatoms are photosynthetic unicellular, eukaryotic, microorganisms (algae) that are distinguished by their silicified (SiO2‐nH2O) cell walls. They have often been employed to assess salinity, pH, and nutrient conditions. Our data suggest that, they may also be used to assess suspended solid levels in streams. The ratio of motile to attached benthic diatoms from five different stream sites in Hong Kong was correlated with the level of suspended solids for each of these sites. Sites with high concentrations of suspended solids had a high percentage of motile diatoms on their rocks while sites with low concentrations of suspended solids had a high percentage of attached (non‐motile) diatoms on their rocks. When water carried by a stream has a high concentration of suspended solids, benthic diatoms in the stream are often covered in a layer of silt. Those diatoms that are motile are able to get on top of this silt layer while attached diatoms cannot. If the silt layer is not washed away, the attached diatoms perish and the percentage of motile diatoms increases. Thus, streams with high concentrations of suspended solids display a higher proportion of motile diatoms than do clear water streams with low concentrations of suspended solids.

Published: July 2005

The use of recombinant human bone morphogenetic protein‐2 (rhBMP‐2) to induce ectopic bone formation requires a carrier. Type I atelocollagen, a biomaterial with a porous structure, excellent operational features, and biocompatibility, is an effective carrier for rhBMP‐2. However, the conventionally used lyophilized rhBMP‐2/collagen mixture does not necessarily give adequate bone‐induction effect. In the present study, we examined the effect of immobilizing rhBMP‐2 to type I atelocollagen on the cellular activity of ST2 cells. The following results were obtained: (1) rhBMP‐2 was effectively immobilized to succinylated type I atelocollagen, indicating the usefulness of succinylated type I atelocollagen in immobilization; (2) studies of alkaline phosphatase activity confirmed the effectiveness of rhBMP‐2 immobilized on succinylated atelocollagen in augmenting cellular activity. © Wiley Periodicals, Inc.

Pulmonary inflammation caused by chitosan microparticles
Authors: Huang Y. C. , Vieira A. , Huang K. L. , Yeh M. K. , Chiang C. H.
Published: July 2005

Chitosan is a cationic biopolymer derived from chitin with potential therapeutic applications such as controlled drug delivery to mucosal‐epithelial surfaces in the body. Inhaled chitosan microparticles (CM), for example, are of potential interest in pulmonary pharmacotherapy. In this context, we examine some basic reactions of lung tissue to CM. Inhaled CM (2–10 mg/kg of particles) induce dose‐dependent proinflammatory effects in rat lungs; these effects are documented in increases in bronchoalveolar lavage fluid protein (BALF‐P) and lactate dehydrogenease activity (BALF‐LDH) and increases in lung tissue myeloperoxidase (MPO) activity and leukocyte migration. Overall, the biochemical parameters (i.e., average of BALF‐P, BALF‐DH, and MPO) indicate that the inflammation response is 1.8‐fold greater than controls without CM; the same inflammation parameters, however, are 1.9‐fold lower with CM compared with the proinflammatory effects of lipopolysaccharide (LPS). Cytological examination of BALF shows a large infiltration of polymorphonuclear neutrophils to lung tissue: more than a sixfold increase in this population of inflammatory cells, after inhalation of CM relative to air inhalation controls. Thus, the results indicate that inhaled CM can have significant proinflammatory effects on lung tissues; these effects are mild relative to LPS but need to be considered in the context of therapeutic applications via pulmonary delivery if such concentrations of CM are used. © 2005 Wiley Periodicals, Inc.

Published: July 2005

Membranes made from 84% deacetylated chitosan biopolymer were cross‐linked by a novel method using 2,4‐toluylene diisocyanate (TDI) and tested for the separation of t‐butanol/water mixtures by pervaporation. The unmodified and cross‐linked membranes were characterized by Fourier transform infra red (FTIR) spectroscopy, X‐ray diffraction (XRD) studies and sorption studies in order to understand the polymer–liquid interactions and separation mechanisms. Thermal stability was analyzed by differential scanning calorimetry (DSC) and thermo gravimetric analysis (TGA) while tensile strength measurement was carried out to assess mechanical strength. The membrane appears to have good potential for breaking the aqueous azeotrope of 88.2 wt% t‐butanol by giving a high selectivity of 620 and substantial water flux (0.38 kg m−2 hr−1). The effects of operating parameters such as feed composition, membrane thickness and permeate pressure on membrane performance were evaluated. Copyright © 2005 Society of Chemical Industry
Characterisation of Blends Based on Hydroxyethylcellulose and Maleic Acid‐alt‐Methyl Vinyl Ether
Authors: Khutoryanskaya Olga V. , Khutoryanskiy Vitaliy V. , Pethrick Richard A.
Published: July 2005

Summary: Hydrophilic polymeric films based on blends of hydroxyethylcellulose and maleic acid‐co‐methyl vinyl ether were produced by casting from aqueous solutions. The physicochemical properties of the blends have been assessed using Fourier transform infrared spectroscopy, thermal gravimetric analysis, differential scanning calorimetry, dielectric spectroscopy, etc. The pristine films exhibit complete miscibility due to the formation of intermacromolecular hydrogen bonding. The thermal treatment of the blend films leads to cross‐linking via intermacromolecular esterification and anhydride formation. The cross‐linked materials are able to swell in water and their swelling degree can be easily controlled by temperature and thermal treatment time. The formation of the crosslinks is apparent in the dynamic properties of the blends as observed through the mechanical relaxation and dielectric relaxation spectra. The dielectric characteristics of the material are influenced by the effects of change in the local structure of the blend on the ionic conduction processes and the rate of dipolar relaxation. Separation of these processes is attempted using the dielectric modulus method. Significant deviations from a simple additive rule of mixing on the activation energy are observed consistent with hydrogen bonding and crosslinking of the matrix. This paper indicates a method for the creation of films with good mechanical and physical characteristics by exposing the blends to a relatively mild thermal treatment.
