Efficacy and safety of long-term treatment with lenalidomide and dexamethasone in patients with relapsed/refractory multiple myeloma
Authors: Dimopoulos M A , Swern A S , Li J S , Hussein M , Weiss L , Nagarwala Y , Baz R
Published: November 2014

Data from two randomized pivotal, phase 3 trials evaluating the combination of lenalidomide and dexamethasone in relapsed/refractory multiple myeloma (RRMM) were pooled to characterize the subset of patients who achieved long-term benefit of therapy (progression-free survival ⩾3 years). Patients with long-term benefit of therapy (n=45) had a median duration of treatment of 48.1 months and a response rate of 100%. Humoral improvement (uninvolved immunoglobulin A) was more common in patients with long-term benefit of therapy (79% vs 55%; P=0.002). Significant predictors of long-term benefit of therapy in multivariate analysis were age<65 years (P=0.03), β2-microglobulin <2.5 mg/l (P=0.002) and fewer prior therapies (P=0.002). The exposure-adjusted incidence rate (EAIR) of grade 3–4 neutropenia was lower in patients with long-term benefit of therapy (13.9 vs 38.2 per 100 patient-years). The EAIR for invasive second primary malignancy was the same in patients with long-term benefit of therapy and other patients (1.7 per 100 patient-years). These findings indicate that patients with RRMM can experience long-term benefit with lenalidomide and dexamethasone treatment with manageable side effects.
Endogenous florendoviruses are major components of plant genomes and hallmarks of virus evolution

Published: November 2014

The extent and importance of endogenous viral elements have been extensively described in animals but are much less well understood in plants. Here we describe a new genus of Caulimoviridae called ‘Florendovirus’, members of which have colonized the genomes of a large diversity of flowering plants, sometimes at very high copy numbers (>0.5% total genome content). The genome invasion of Oryza is dated to over 1.8 million years ago (MYA) but phylogeographic evidence points to an even older age of 20–34 MYA for this virus group. Some appear to have had a bipartite genome organization, a unique characteristic among viral retroelements. In Vitis vinifera, 9% of the endogenous florendovirus loci are located within introns and therefore may influence host gene expression. The frequent colocation of endogenous florendovirus loci with TA simple sequence repeats, which are associated with chromosome fragility, suggests sequence capture during repair of double-stranded DNA breaks.
Aggregation and morphology control enables multiple cases of high-efficiency polymer solar cells

Published: November 2014

Although the field of polymer solar cell has seen much progress in device performance in the past few years, several limitations are holding back its further development. For instance, current high-efficiency (>9.0%) cells are restricted to material combinations that are based on limited donor polymers and only one specific fullerene acceptor. Here we report the achievement of high-performance (efficiencies up to 10.8%, fill factors up to 77%) thick-film polymer solar cells for multiple polymer:fullerene combinations via the formation of a near-ideal polymer:fullerene morphology that contains highly crystalline yet reasonably small polymer domains. This morphology is controlled by the temperature-dependent aggregation behaviour of the donor polymers and is insensitive to the choice of fullerenes. The uncovered aggregation and design rules yield three high-efficiency (>10%) donor polymers and will allow further synthetic advances and matching of both the polymer and fullerene materials, potentially leading to significantly improved performance and increased design flexibility.

Published: November 2014

In patients who are receiving prolonged antiretroviral treatment (ART), HIV can persist within a small pool of long-lived resting memory CD4+ T cells infected with integrated latent virus. This latent reservoir involves distinct memory subsets. Here we provide results that suggest a progressive reduction of the size of the blood latent reservoir around a core of less-differentiated memory subsets (central memory and stem cell-like memory (TSCM) CD4+ T cells). This process appears to be driven by the differences in initial sizes and decay rates between latently infected memory subsets. Our results also suggest an extreme stability of the TSCM sub-reservoir, the size of which is directly related to cumulative plasma virus exposure before the onset of ART, stressing the importance of early initiation of effective ART. The presence of these intrinsic dynamics within the latent reservoir may have implications for the design of optimal HIV therapeutic purging strategies.
Broadband focusing and collimation of water waves by zero refractive index
Authors: Zhang Chi , Chan C. T. , Hu Xinhua
Published: November 2014

It is always a challenge to realize extreme and unusual values of refractive index for a broad range of frequencies. We show that when water is covered by a thick, rigid and unmovable plate, it behaves like a medium with zero refractive index for water waves at any frequency. Hence, by covering water with a plate of a concave or rectangular shape, water waves can be focused or collimated in a broad range of frequencies. Experiments were conducted to demonstrate these effects and results are in excellent agreement with numerical simulations.

Published: November 2014

Here we present measurements on a metasurface composed by tilted gold nanowires. The metasurface can induce an optical chiral response of the whole sample when the light impinges on the sample out of the normal incidence angle. In order to investigate the symmetry breaking induced by the geometry, we measured the second harmonic generation (SHG) signal generated by circular polarized pulsed light. This technique has demonstrated to be a powerful method in order to investigate the chiral morphology of nanostructures.

Microdiskectomy and Translaminar Approach: Minimal Invasiveness and Flavum Ligament Preservation
Authors: Vanni Daniele , Sirabella Francesco S. , Guelfi Matteo , Pantalone Andrea , Galzio Renato , Salini Vincenzo , Magliani Vincenzo
Published: November 2014

Study Design

Retrospective study.

Objective

The interlaminar approach represents the standard procedure for the surgical treatment of lumbar disk herniation (LDH). In the case of disk herniations in the “hidden zone,” it could be necessary to perform laminotomies or laminectomies and partial or total facetectomies to remove the herniated fragment, thus leading to iatrogenic instability. The objective of the study is to evaluate the translaminar approach, in terms of the results, safety, and efficacy compared with the standard approach.

Methods

Since February 2010, 38 patients (26 men and 12 women; mean age 50.9 years, range 31 to 78 years) with LDH and migration into the hidden zone underwent a microdiskectomy by the translaminar approach. Using a micro-diamond dust-coated burr, a translaminar hole (8 ± 2 mm) was made, with subsequent exposure of the involved root and removal of the fragment. A clinical follow-up was performed at months 1, 3, 6, and 12 using the visual analog scale and the Oswestry Disability Index. All patients were evaluated according to the Spangfort score. Postoperative radiographic evaluations were done at 1, 6, and 12 months (dynamic radiographic studies done at 6 and 12 months).

Results

In over 60% of cases, L4–L5 was the involved disk. The visualization of the roots was successfully achieved through a translaminar approach. No laminotomies, laminectomies, or partial or total facetectomies were performed. The flavum ligament was always spared. A severe intraoperative bleeding episode occurred in 5% of the cases, due to involvement of the epidural veins, but it did not result in prolonged operative time (mean duration 60 ± 10 minutes). The patients showed a gradual resolution of the back pain and a progressive resolution of the radicular pain and the neurologic deficits. No sign of radiographic instability was documented during the follow-up. No infections, dural tears, or spinal cord injuries occurred. No revision surgery was performed.

Conclusion

The translaminar approach is the only tissue-sparing technique viable in case of cranially migrated LDH encroaching on the exiting nerve root in the preforaminal zones, for the levels above L2–L3, and in the preforaminal and foraminal zones, for the levels below L3–L4 (L5–S1 included, if a total microdiskectomy is not necessary). The possibility to spare the flavum ligament is one of the main advantages of this technique. According to our experience, the translaminar approach is an effective and safe alternative minimally invasive surgical option.

The repeated use of glyphosate to control annual ryegrass along fence lines and crop margins has resulted in the evolution of resistance to this herbicide in populations of annual ryegrass (Lolium rigidum) in cropping regions of Australia. Field trials were conducted between 2009 and 2011 at four fence-line sites in South Australia to identify suitable herbicide treatments for controlling glyphosate-resistant annual ryegrass. Annual ryegrass populations growing at all four sites were found to have 12–24-fold resistance to glyphosate compared with a standard susceptible population in dose-response experiments. Glyphosate alone (1080 g ha–1) did not effectively control glyphosate-resistant annual ryegrass at any location. Single applications of paraquat + diquat and paraquat + amitrole were effective where weed populations were low, with up to 99% reduction in seed-head production. Mixtures of paraquat + diquat + diuron, glufosinate ammonium + diuron and two applications of paraquat + diquat 14 days apart consistently provided high levels of control of glyphosate-resistant annual ryegrass at all locations, with >90% reduction in seed-head production. In 2011, glyphosate resistant individuals of annual ryegrass were identified up to 50 m inside the fields adjacent to the fence. Therefore, failure to control glyphosate-resistant annual ryegrass along crop margins risks movement of resistance into adjacent cropped fields.

Arthur Melville (‘Mel') Thompson graduated from the University of Adelaide in 1938 with First Class Honours in Physics. After graduation he joined Australia's Council for Scientific and Industrial Research as one of the ‘founding fathers' of the National Standards Laboratory and embarked on a life-time career in metrology. His work in precision electrical measurement, ratio-arms transformer bridges and techniques for defining and measuring small capacitances is internationally renowned. He conceived the design of a calculable-capacitor, the Thompson-Lampard capacitor, which led to a new theorem in electrostatics and provided the basis for an absolute determination of the unit of resistance with an increase in accuracy of an order of magnitude. Beyond the calculable capacitor his work had a major impact in electrical impedance measurement in general and on other fields of metrology such as dilatometry and thermometry. Mel Thompson was an inspirational leader and his work facilitated the development of many scientific careers.

Colin Russell Austin, English by birth, initially graduated in Veterinary Science from the University of Sydney in 1936. The Second World War limited his career options, but he was fortunate to be employed by the CSIR Division of Animal Health in Sydney. In 1954 he was invited to join the staff of the Medical Research Council's laboratory in Mill Hill, London to study fertilization and early embryonic development in rats and rabbits. As a result, in 1962 he was asked to teach Fertilization and Gamete Physiology at the Marine Biological Laboratory, Woods Hole, Massachusetts, and subsequently became Professor of Embryology in the Medical School at Tulane University, New Orleans. This alerted the University of Cambridge to his potential and they created a special Charles Darwin Chair for him in 1967. This enabled him to support the work of his young student Robert Edwards on human in vitro fertilization and embryonic development that culminated in the award of the Nobel Prize to Edwards and Patrick Steptoe in 2010. Austin also devoted a great deal of his time to editing the 13-volume Cambridge University Press series of textbooks, Reproduction in Mammals, completing the series from his retirement home in Buderim, Queensland in 1986.

Ovarian hyperstimulation syndrome (OHSS) is a complication of ovarian stimulation with gonadotrophins following human chorionic gonadotrophin (hCG) administration. The relationship between hCG and OHSS is partly mediated via the production of angiogenic factors, such as vascular endothelial growth factor A (VEGFA) and angiopoietins (ANGPTs). Here, we investigated the effect of ANGPT1 inhibition on ovarian angiogenesis in follicular fluid (FF) from women at risk of OHSS, using the chorioallantoic membrane (CAM) of quail embryos as an experimental model. We also analysed cytoskeletal changes and endothelial junction protein expression induced by this FF in the presence or absence of an ANGPT1-neutralising antibody in endothelial cell cultures. The presence of this antibody restored the number of vascular branch points and integrin αvβ3 levels in the CAMs to control values. ANGPT1 inhibition in FF from OHSS patients also restored the levels of claudin-5, vascular endothelial cadherin and phosphorylated β-catenin and partially reversed actin redistribution in endothelial cells. Our findings suggest that ANGPT1 increases pathophysiological angiogenesis in patients at risk of OHSS by acting on tight and adherens junction proteins. Elucidating the mechanisms by which ANGPT1 regulates vascular development and cell–cell junctions in OHSS will contribute to identifying new therapeutic targets for the treatment of human diseases with aberrant vascular leakage.

Most of Inner Mongolia is covered with natural grassland and is highly sensitive to global climate change because of the physical geography, the highly variable climate, and the complicated socioeconomic conditions. The climate is generally wetter in the east becoming drier towards the west of the region. Using a Pressure-State-Response model to select climate-related assessment indicators, a vulnerability assessment to climate change framework of counties in Inner Mongolia was built, which included three layers and 17 indicators. Climate change vulnerability of eight counties in the steppe area of Inner Mongolia was assessed from 1980 to 2009. The results showed that in the past 30 years, climate change vulnerability of eight counties has decreased with the decrease more pronounced after 2000. The lowest value for vulnerability was in 2008. The vulnerability of the western region was higher than that of the eastern region. Counties with a desert ecological system had a higher vulnerability than counties with steppe. Under the background of exposure increasing and sensitivity slightly decreasing, a continuing significant improvement in adaptive capacity is the key reason for a reduction invulnerability of the Inner Mongolia steppe area to climate change. The volatility of the climate on an inter-annual scale can cause changes in vulnerability between years. With the development of the rural economy and increases in national investment in the environment, the vulnerability of the Inner Mongolian steppe has been significantly reduced, but, overall, the vulnerability remains high. Most of the counties are moderately vulnerable, some counties are seriously vulnerable, even extremely vulnerable, and strong measures need to be adopted to strengthen the ability to adapt to climate change.

The Weather Research and Forecasting mesoscale atmospheric model was used to investigate fire weather conditions during the 2009–10 New Zealand wildland fire season. The analysis considered New Zealand's version of the Fire Weather Index used in the Canadian Forest Fire Danger Rating System, the Haines Index (HI) and the Continuous Haines Index (CHI). This represents the first investigation in New Zealand of the HI and CHI, which rate the potential for extreme fire behaviour or large fire growth based on the lower tropospheric atmospheric stability and humidity. The wildland fire activity during the 2009–10 fire season was typical of New Zealand, and there was considerable spatial and temporal variability in the fire weather conditions. The most frequent severe fire weather conditions as quantified by the fire weather indices occurred to the east of the dividing mountain ranges in both the North Island and South Island, and were associated with the hot, dry and windy north-westerly foehn winds that commonly affect New Zealand. The 36 wildland fires greater in area than 5 ha during the 2009–10 fire season occurred under a range of fire weather conditions, and no correlation was found between the wildland fire size and each individual weather variable.
Floating around in the Dutch nominal domain
Authors: Corver Norbert
Published: November 2014

In this article I investigate the internal syntax of Dutch nominal expressions liketwee slangen van elk twee meter(two snakes of each two meter). The prepositionvanseparates the quantifierelkfrom the expressiontwee slangento which it is connected interpretatively. From a purely observational view, the quantifier could be said to be floating in the nominal domain. In this article I argue that this floatingelkis an instance of so-called ‘binominaleach’. So far, discussions of the binominal-each-phenomenon have concentrated on dependencies involving material in the clausal domain. In this article I show that dependencies involving binominalelkare also attested DP-internally. Syntactic issues that will be discussed in the context of the DP-internal binominal-each-phenomenon include: Constituency of the nominal expression, the nature of the DP-internal anaphoric dependency, the various manifestations of the binominal pattern, and word order rearrangements by DP-internal displacement.
Variation in verb cluster interruption
Authors: Hendriks Lotte
Published: November 2014

Except for finite verbs in main clauses, verbs in Standard Dutch cluster together in a clause-final position. In certain Dutch dialects, non-verbal material can occur within this verb cluster (Verhasselt 1961; Koelmans 1965, among many others). These dialects vary with respect to which types of elements can interrupt the verb cluster, varying from particles to various types of arguments and adverbs (Barbiers, van der Auwera, Bennis, Boef, de Vogelaer & van der Ham 2008). A study amongst forty Dutch dialect speakers reveals an ordered ranking of grammatical types, reflecting their acceptability in a verb cluster. I argue that this ranking directly follows from syntactic principles: The syntactic size and position of the intervening element affect its acceptance in a verb cluster. Potentially, these principles interact with a preference of performance dubbed ‘minimize domains’ (Hawkins 1994, 2003, 2004), which requires both the higher verb and the intervening element to be adjacent to the main verb, leading to two conflicting structures.
Resultative constructions in heritage Ambon Malay in the Netherlands
Authors: Moro Francesca R.
Published: November 2014

Domains where languages have two or more competing syntactic constructions expressing the same meaning may be problematic for bilingual heritage speakers. One such variable domain is the resultative constructions in heritage Ambon Malay, a variety spoken in the Netherlands by Dutch-Ambon Malay bilinguals. In Ambon Malay, resultatives are expressed mostly by means of verb serialization (SVC), although resultative prepositional phrases (PP) and adjectival phrases (AP) also occur. In Dutch, resultative constructions usually involve verb particles, PPs and APs. This overlap of structures poses the conditions for transfer effects between the two languages. The frequency distribution of SVCs, PPs and APs is investigated in semi-spontaneous speech from heritage speakers of Ambon Malay and compared to that of baseline speakers. Heritage speakers show an increase in the frequency of constructions shared by both languages (PPs and APs), while they underuse the constructions attested only in the heritage language (SVC).
Erring on the side of phonology
Authors: Strycharczuk Patrycja , Sebregts Koen
Published: November 2014

Speakers of Standard Dutch increasingly realise coda /r/ (e.g.paar) as a bunched or retroflex approximant. This coda variant is categorically distinct from onset /r/ (e.g.reizen), which is typically pronounced as a uvular trill or fricative, or an alveolar trill or tap. In this study, we investigate whether coda and onset /r/ in Dutch behave as distinct phonological categories. We present new articulatory and acoustic data on the realisation of /r/ in sandhi contexts, including the fake geminate context (e.g.paar reizen). Ultrasound data show that the presence of an onset /r/ conditions the deletion of a bunching gesture (typical of the coda /r/ realisation) from /r#r/ sequences. Nevertheless, the presence of a coda /r/ in such sequences is still acoustically traceable. We interpret these findings as a result of shared phonological identity between onset and coda /r/, and discuss them in the context of the place of allophony within models of grammar.
The Dutch ‘X is zo + NP/VP’-construction
Authors: Sweep Josefien
Published: November 2014

This paper analyses Dutch sentences from a commercial campaign which make use of the ‘X is zo NP/VP’-construction. I consider this to be a construction (cf. Goldberg 1995; Verhagen 2005), not only because of its template-like character in which the adverb zo is followed by an unusual phrase type, but also because of its unexpected semantic properties. The analysis of this construction reveals a part of the Dutch ‘constructicon’.
De ontwikkeling van taalbeleid binnen Geesteswetenschappen aan de Universiteit van Amsterdam
Authors: Kuiken Folkert , van Kalsbeek Alice
Published: November 2014

In dit artikel gaan we in de eerste plaats in op de vraag in hoeverre we ons zorgen moeten maken omtrent de taalvaardigheid in het Nederlands van studenten in het hoger onderwijs en met welke taalproblemen studenten vooral kampen. Vervolgens is het de vraag hoe aan deze problemen het hoofd kan worden geboden. We doen dat aan de hand van de manier waarop taalbeleid aan de Universiteit van Amsterdam (UvA) tot stand is gekomen, waarvan de kiem binnen de Faculteit der Geesteswetenschappen (FGw) is gelegd. We gaan daarbij met name in op het zogeheten Diversiteitsproject dat in 2011–2012 aan deze faculteit is uitgevoerd. Op basis van de resultaten van dit project komen we tot een aantal randvoorwaarden voor succesvol taalbeleid en bespreken we een aantal suggesties voor verder onderzoek.
