Azabicycloalkenes as Synthetic Intermediates – Synthesis of Conformationally Constrained Glutamate Analogues
Authors: Maison Wolfgang
Published: March 2007

As a part of our study of the cancer‐specific protease PSMA (prostate‐specific membrane antigen) we present a stereoselective synthesis of conformationally constrained glutamate mimetics. Key intermediates are azabicycloalkenes which are synthesized via diastereoselective or enantioselective imino‐Diels–Alder protocols. The versatility of the route is demonstrated with the preparation of Asp, Glu and HGlu‐mimetics based on proline or pipecolic acid scaffolds. These scaffolds are assembled by an oxidative cleavage of azabicycloalkenes and subsequent conversions of the resulting dialdehydes via chlorite oxidation or Wittig olefination. The resulting cyclic amino acids are obtained as Cbz‐protected derivatives or free amines ready for further manipulation at their N‐terminus and are useful as building blocks for the assembly of conformationally rigid PSMA ligands.(© Wiley‐VCH Verlag GmbH & Co.

Authors: Coletta Antonio
Published: March 2007

The Standard ISO/IEC 15504, has been developed for the purpose of performing assessments of software and systems processes. The result is a capability‐level rating for each assessed process on a rating scale from 0 to 5. The capability levels defined in the ISO/IEC 15504 measurement framework have been designed to be applicable universally to all types of processes. Aside from level 1 (the performed level) where the observable indicators differ from process to process, all the attributes from level 2 to 5 should be common and observable for all types of processes. A practical application of this feature is the possibility to perform assessments on processes from other industrial sectors (e.g. manufacturing processes), using the same measurement framework as long as we have the process defined according to specific rules.

An industrial experiment in this area was carried out by DNV on some critical processes deployed by a large company in charge of managing the Italian national gas distribution network (SNAM Rete Gas).

Specific process definitions were developed with the purpose and outcome as required by the Standard for a Process Reference Model. In order to build the Process Assessment Model, performance indicators were also identified while capability indicators from levels 2 to 5 were taken straight from the Standard (part 5).

The assessment was successfully performed on two different processes providing the organization with valuable insights on their process.

This article will illustrate step by step, how this industrial experiment was carried out and what were its results. Copyright © 2007 John Wiley & Sons, Ltd.
Positional distribution of octadecadienoic acids in sponge phosphatidylethanolamines
Authors: Carballeira Néstor M. , Emiliano Anastacio , Morales Reginald
Published: March 2007

The distribution of C14–C22 fatty acids in the phosphatidylethanolamines isolated from the spongesAgelas sp. andSpongia tampa was investigated. Selective changes with phospholipase A2 (fromAgkistrodon halys blomhoffii) followed by thin‐layer chromatographic separation of the resulting lysophosphatidylethanolamines and free fatty acids and subsequent methylation with HCl/MeOH and diazomethane, respectively, revealed that the 5,9‐octadecadienoic acid and the 9,12‐octadecadienoic acid present showed no preference for either positionsn‐1 orsn‐2 in these phosphatidylethanolamines. The other saturated and unsaturated fatty acids with chains between 14 and 22 carbons long were also found to be equally distributed between positionssn‐1 andsn‐2 in the phosphatidylethanolamines in these sponges. The results contrast with what is known about the distribution in most mammalian phospholipids, such as the phosphatidylcholines from human erythrocytes, where octadecadienoic acid typically occupies thesn‐2 position.
Reversal of multidrug resistance of vincristine‐resistant gastric adenocarcinoma cells through up‐regulation of DARPP‐32

Published: March 2007

Here we investigated the roles of DARPP‐32 in multidrug resistance (MDR) of gastric cancer cells and the possible underlying mechanisms. We constructed the eukaryotic expression vector of DARPP‐32 and transfected it into human vincristine‐resistant gastric adenocarcinoma cell line SGC7901/VCR. Up‐regulation of DARPP‐32 could significantly enhance the sensitivity of SGC7901/VCR cells towards vincristine, adriamycin, 5‐fluorouracil and cisplatin, and could decrease the capacity of cells to efflux adriamycin. What's more, the results of subrenal capsule assay confirmed that DARPP‐32 might play a certain role in MDR of gastric cancer. DARPP‐32 could significantly down‐regulate the expression of P‐gp and zinc ribbon domain‐containing 1 (ZNRD1), but not alter the expression of multidrug resistance‐associated protein (MRP) or the glutathione S‐transferase (GST). DARPP‐32 could also significantly decrease the anti‐apoptotic activity of SGC7901/VCR cells. Further study of the biological functions of DARPP‐32 might be helpful for understanding the mechanisms of MDR in gastric cancer.
Cloud‐SST feedback in southeastern tropical Atlantic anomalous events
Authors: Huang Bohua , Hu Zeng‐Zhen
Published: March 2007

Using satellite‐based cloud measurements for 1984–2004, the interannual variability of the low‐level cloud cover over the tropical Atlantic Ocean in austral winter (June–July–August, JJA) is examined. It is found that the leading pattern of the low‐cloud anomalies in this season is a modulation of the climatological center of the cloud cover over the southeastern tropical Atlantic Ocean off the Angola and Namibia coasts. The fluctuation of cloud amount there occurs on both interannual and longer timescales. The relationship between this low‐cloud anomalous pattern and basinwide ocean‐atmosphere anomalies is studied through a composite analysis based on the objectively selected major low‐cloud deficit and excess years. For the composites we intentionally use data sets mainly based on satellite measurements for the past one to two decades to minimize the potential influences of the bias in the model‐based ocean‐atmosphere analyses. The composites show that the JJA anomalous cloud pattern is strongly influenced by the sea surface temperature (SST) anomalies of the equatorial and southeastern tropical Atlantic Ocean in the previous summer. The anomalous surface warm events off the southwestern coast of Africa near 15°S in January and February are usually initiated dynamically by remote forcing from the westerly wind anomalies over the western equatorial Atlantic, preceding the cloud anomalies. During the next few months, the warm water is spread into the southeastern tropical Atlantic Ocean and is conducive to deficit low‐cloud cover in subsequent JJA. The reduced low‐cloud cover in turn forces positive SST tendency in a larger area of the southeastern Atlantic Ocean by changing the amount of the local solar radiation reaching the sea surface. In June and July, this process moves the major center of the SST anomalies away from the coast and closer to the equator when the coastal process weakens. The low cloud‐radiation‐SST feedback also plays a role in the slow westward expansion of the SST anomalies in late austral winter and spring. Overall, the influence of the cloud fluctuation is an important component in the evolution of the southeastern tropical Atlantic anomalous events.

RNA interference (RNAi) has been shown to be a powerful method to study the function of genes
in vivo
by silencing endogenous mRNA with double-stranded (ds) RNA. Previously, we performed
in vivo
RNAi screening and identified 43
Drosophila
genes, including 18 novel genes required for the development of the embryonic nervous system. In the present study, 22 additional genes affecting embryonic nervous system development were found. Novel RNAi-induced phenotypes affecting nervous system development were found for 16 of the 22 genes. Seven of the genes have unknown functions. Other genes found encode transcription factors, a chromatin-remodeling protein, membrane receptors, signaling molecules, and proteins involved in cell adhesion, RNA binding, and ion transport. Human orthologs were identified for proteins encoded by 16 of the genes. The total number of dsRNAs that we have tested for an RNAi-induced phenotype affecting the embryonic nervous system, including our previous study, is 7,312, which corresponds to ≈50% of the genes in the
Drosophila
genome.

Link of groups and homogeneous Hörmander operators
Authors: Kogoj Alessia , Lanconelli Ermanno
Published: March 2007

We study a notion of link of Lie groups suggested by the structure of the partial differential operators of Kolmogorov type. As an application of our link procedure we construct explicit examples of stratified Lie groups, with dimension and step arbitrarily large. We also give a set of examples of hypoelliptic second-order operators which are left translation invariant and homogeneous of degree two on the previous groups.

Wiener’s lemma for infinite matrices
Authors: Sun Qiyu

The classical Wiener lemma and its various generalizations are important and have numerous applications in numerical analysis, wavelet theory, frame theory, and sampling theory.

Atracurium besylate in paediatric anaesthesia
Authors: Lavery G.G. , Mirakhur R.K.
Published: March 2007

Atracurium was evaluated in clinical anaesthesia in 50 children undergoing elective surgery. The rime to onset of maximum block (182 seconds) was similar to that of vecuronium but shorter than that of pancuronium as previously reported. The duration of clinical relaxation (33 minutes) is between those of vecuronium and pancuronium. The anrugonism of block at 25% recovery was easy. There were no untoward cardiovascular effects but skin reactions were observed in over 30% of patienis.
