Making agricultural landscapes more sustainable for freshwater biodiversity: a case study from southern England
Authors: Davies Bella , Biggs Jeremy , Williams Penny , Thompson Stewart 
Published: December 2008

Abstract
Agriculture is known to have a range of deleterious impacts on freshwater habitats and biota and many countries have introduced measures to attempt to mitigate these impacts through agri‐environment initiatives. Despite the protection they provide, water bodies (any discrete body of surface fresh water) in farmland landscapes commonly remain impaired by agriculture. In some areas of the UK there have been calls to halt farming completely, indicating that the measures offered for the widespread protection of aquatic systems, particularly the use of buffer strips, may not be extensive enough to provide sufficient protection for freshwater biota.
This study investigated whether existing agri‐environment measures for the widespread protection of aquatic habitats could be better deployed to provide a higher level of protection for the aquatic macrophytes and macroinvertebrates of a study area in southern England.
Reserve selection procedures were used to reallocate the area of land that could be remunerated under the Environmental Stewardship scheme as buffer strips bordering water bodies, so that a higher level of protection was provided for both the richness and rarity of aquatic species in the study area.
Almost 395 ha were available for reallocation in the reserve selection process, which was found to provide a satisfactory level of protection for up to 90% of the surveyed species.
The results showed that the agri‐environment scheme in England has a great deal of potential to provide more effective protection for the aquatic biodiversity of agricultural landscapes if measures are targeted.

BVideoQA: Online English/Chinese bilingual video question answering
Authors: Lee Yue‐Shi , Wu Yu‐Chieh , Yang Jie‐Chi 
Published: December 2008

AbstractThis article presents a bilingual video question answering (QA) system, namely BVideoQA, which allows users to retrieve Chinese videos through English or Chinese natural language questions. Our method first extracts an optimal one‐to‐one string pattern matching according to the proposed dense and longN‐gram match. On the basis of the matched string patterns, it gives a passage score based on our term‐weighting scheme. The main contributions of this approach to multimedia information retrieval literatures include: (a) development of a truly bilingual video QA system, (b) presentation of a robust bilingual passage retrieval algorithm to handle no‐word‐boundary languages such as Chinese and Japanese, (c) development of a large‐scale bilingual video QA corpus for system evaluation, and (d) comparisons of seven top‐performing retrieval methods under the fair conditions. The experimental studies indicate that our method is superior to other existing approaches in terms of precision and main rank reciprocal rates. When ported to English, encouraging empirical results also are obtained. Our method is very important to Asian‐like languages since the development of a word tokenizer is optional.
Update on prevention of folic acid‐preventable spina bifida and anencephaly
Authors: Bell Karen N. , Oakley Godfrey P. 
Published: December 2008

AbstractBACKGROUND: The number of countries fortifying wheat and maize flour with folic acid has increased in the past 2 years. Folic acid prevents most cases of spina bifida and anencephaly by raising serum folate levels among women capable of bearing children, as does encouraging women to consume folic acid supplements prior to pregnancy. METHODS: The progress in preventing these serious birth defects can be measured by tracking the number of countries now fortifying and program coverage in each. Country estimates of the number of pregnancies affected by spina bifida and anencephaly are calculated using a prefortification birth prevalence baseline and estimates of the proportion prevented by wheat and maize flour fortified with folic acid. RESULTS: Current fortification programs are preventing about 22,000, or 9% of the estimated folic acid‐preventable spina bifida and anencephaly cases. This represents an annual global decrease of about 6,600 folic acid‐preventable spina bifida and anencephaly cases since 2006. CONCLUSIONS: The pace of preventing these serious birth defects can be accelerated if more countries require fortification of both wheat and maize flour and if regulators set fortification levels high enough to increase a woman's daily average consumption of folic acid to 400 mcg.

Regeneration: Rewarding, but potentially risky
Authors: Egger Bernhard 
Published: December 2008

AbstractSome bilaterally symmetric animals, such as flatworms, annelids, and nemerteans, are renowned for their outstanding regeneration capacity—even a fraction of the body can give rise to a complete new animal. However, not all species of these taxa can regenerate equally well—some cannot regenerate at all. If regeneration was purely beneficial, why cannot all of members of the flat, round, and ribbon worms regenerate? At that, why cannot all other bilaterians, including humans, regenerate as well? Regeneration capacity is an obvious advantage in accidental, predatory, and parasitic loss of body parts and is also closely intertwined with asexual reproduction strategies. Regeneration is suspected to play a role in life span extension or even rejuvenation. An answer for reduced or missing regeneration capacity in many species may be found in limitations of the body plan, high costs, and inherent dangers of regeneration. Defects in adults and juveniles are shown, and similarities between development and regeneration are pointed out. With a focus on some worms, but also highlighting comparisons with other animal taxa, putative reasons for a limited and an advanced regeneration capacity are discussed in this article.

Stenting for a symptomatic posterior cerebral artery stenosis
Authors: Xu Gelin , Zheng Ling , Zhou Zhiming , Liu Xinfeng 
Published: December 2008

AbstractEvolvement of endovascular devices and increase of operator expertise have made angioplasty and stenting in intracranial vessels technically possible. Stenting has been reported in treating stenosis in middle and anterior cerebral arteries with favorable outcomes. However, the feasibility of stenting for stenosis in posterior cerebral artery (PCA) has not been established. We report a patient with progressive focal cerebral ischemic symptoms, which were arrested after reconstruction of the associated PCA stenosis with stenting. © 2008 Wiley‐Liss, Inc.

AbstractObjective: To evaluate the clinical utility of images acquired from rotational coronary angiographic (RA) acquisitions compared to standard “fixed” coronary angiography (SA). Background: RA is a novel angiographic modality that has been enabled by new gantry systems that allow calibrated automatic angiographic rotations and has been shown to reduce radiation and contrast exposure compared to SA. RA provides a dynamic multiple‐angle perspective of the coronaries during a single contrast injection. Methods: The screening adequacy, lesion assessment, and a quantitative coronary analysis (QCA) of both SA and RA were compared by independent blinded review in 100 patients with coronary artery disease (CAD). Results: SA and RA recognize a similar total number of lesions (P = 0.61). The qualitative assessment of lesion characteristics and severity between modalities was comparable and lead to similar clinical decisions. Visualization of several vessel segments (diagonal, distal RCA, postero‐lateral branches and posterior‐descending) was superior with RA when compared to SA (P < 0.05). A QCA comparison (MLD, MLA, LL, % DS) revealed no difference between SA and RA. The volume of contrast (23.5 ± 3.1 mL vs. 39.4 ± 4.1; P = 0.0001), total radiation exposure (27.1 ± 4 vs. 32.1 ± 3.8 Gycm2; P = 0.002) and image acquisition time (54.3 ± 36.8 vs. 77.67 ± 49.64 sec; P = 0.003) all favored RA. Conclusion: Coronary lesion assessment, coronary screening adequacy, and QCA evaluations are comparable in SA and RA acquisition modalities in the diagnosis of CAD however RA decreases contrast volume, image acquisition time, and radiation exposure. © 2009 Wiley‐Liss, Inc.
Electric‐Field Triggered Controlled Release of Bioactive Volatiles from Imine‐Based Liquid Crystalline Phases
Authors: Herrmann Andreas , Giuseppone Nicolas , Lehn Jean‐Marie 
Published: December 2008

AbstractApplication of an electric field to liquid crystalline film forming imines with negative dielectric anisotropy, such as N‐(4‐methoxybenzylidene)‐4‐butylaniline (MBBA, 1), results in the expulsion of compounds that do not participate in the formation of the liquid crystalline phase. Furthermore, amines and aromatic aldehydes undergo component exchange with the imine by generating constitutional dynamic libraries. The strength of the electric field and the duration of its application to the liquid crystalline film influence the release rate of the expelled compounds and, at the same time, modulate the equilibration of the dynamic libraries. The controlled release of volatile organic molecules with different chemical functionalities from the film was quantified by dynamic headspace analysis. In all cases, higher headspace concentrations were detected in the presence of an electric field. These results point to the possibility of using imine‐based liquid crystalline films to build devices for the controlled release of a broad variety of bioactive volatiles as a direct response to an external electric signal.
Rainbow Perylene Monoimides: Easy Control of Optical Properties
Authors: Li Chen , Schöneboom Jan , Liu Zhihong , Pschirer Neil G. , Erk Peter , Herrmann Andreas , Müllen Klaus 
Published: December 2008

AbstractPerylene dyes have been widely used as photoreceptors in organic photovoltaics because of their outstanding photo‐, thermal and chemical stability as well as their excellent photophysical properties. Herein we describe a novel generation of perylene dyes based on N‐(2,6‐diisopropylphenyl)‐perylene‐3,4‐dicarboximide. The optical properties of these novel perylenes can be finely tuned via the substituents in the 1‐, 6‐ and 9‐positions of the perylene core. The facile synthesis, tunable orbital and absorption properties, and electrochemical potentials help us to design efficient perylene sensitizers for solar‐cell applications.
