Regional innovation strategies rank at the top of public policy agendas today. There is a widespread consensus in both academic and policy circles that standardized "best practice" innovation policy models suffer from severe limitations and major shortcomings. The recent literature is replete with claims that regional innovation policies should be place-based and context-sensitive, taking into con
The role of thalidomide for previously untreated elderly patients with multiple myeloma remains unclear. Six randomized controlled trials, launched in or after 2000, compared melphalan and prednisone alone (MP) and with thalidomide (MPT). The effect on overall survival (OS) varied across trials. We carried out a meta-analysis of the 1685 individual patients in these trials. The primary endpoint wa
Born globals – young, rapidly internationalising small and medium enterprises – face the signifi cant challenge of building an international brand with scarce resources. In this article, we study international brand strategy and implementation of such fi rms, and defi ne the components of brand value to customers in technology B2B markets, which many born globals operate in. On the basis of the fi
Lessons from the occupational arena demonstrate the potential of industrial chemicals to damage human testicular function. An important but still unresolved question is whether low-level xenobiotic exposure of the general population poses a hazard. In this volume of the Asian Journal of Andrology, this issue is addressed by a series of reviews on xenobiotic exposure profiles, possible biological m
Many lines of evidence support that β-amyloid (Aβ) peptides play an important role in Alzheimer's disease (AD), the most common cause of dementia. But despite much effort the molecular mechanisms of how Aβ contributes to AD remain unclear. While Aβ is generated from its precursor protein throughout life, the peptide is best known as the main component of amyloid plaques, the neuropathological hall
BACKGROUND: Tamoxifen has been associated with an increased risk of stroke. There is, however, little information on the effect in the post-treatment period. Using data from the Swedish Breast Cancer Group adjuvant trial of 5 vs 2 years of tamoxifen treatment, we now report both short-term and long-term effects on morbidity as well as mortality because of cerebrovascular disease. METHODS: Data fro
In this work, the water extraction and particle formation on-line (WEPO) process has been used to obtain dry antioxidant powder from rosemary leaves. This process includes pressurized hot water extraction (PHWE) and on-line drying of the extracts in one step. Based on previous works, water extraction at 200 degrees C was selected to achieve the maximum antioxidant activity while water flow rate wa
The present study investigated the effects of land-use abandonment on the soil decomposer community of two grazed Mediterranean ecosystems (an annual grassland with scattered holm oaks and a low-density shrubland). To test the influence of grazing abandonment, a set of plots within each site were fenced and kept undisturbed during 4-5 years, during which above-ground plant community structure was
P>Carbon of terrestrial origin often makes up a significant share of consumer biomass in unproductive lake ecosystems. However, the mechanisms for terrestrial support of lake secondary production are largely unclear. By using a modelling approach, we show that terrestrial export of dissolved labile low molecular weight carbon (LMWC) compounds supported 80% (34-95%), 54% (19-90%) and 23% (7-45%) of
The paper studies the effects of market discipline by creditors and ownership structure on banks' risk taking in the presence of partial deposit insurance. An agency-cost model explains how the effects of creditor discipline and shareholder control arc interdependent, the non-monotonic effect of shareholder control, and the role of leverage. Panel regressions on several hundred banks worldwide 199
This paper represents the opinion of a group of researchers and clinicians with an established interest in poststroke care and is based on the recognised need for long-term care following stroke, especially in view of the global increase of disability due to stroke. Among the more frequent long-term complications following stroke are spasticity-related disabilities. Although spasticity alone occur

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease with chronic or episodic inflammation in many different organ systems, activation of leukocytes and production of pro-inflammatory cytokines. The heterodimer of the cytosolic calcium-binding proteins S100A8 and S100A9 (S100A8/A9) is secreted by activated polymorphonuclear neutrophils (PMNs) and monocytes and serves as a seru
Abstract Objective. The reference standard for lymph-node staging in prostate cancer is currently an extended pelvic lymph-node dissection (ePLND), which detects most, but not all, regional lymph-node metastases. As an alternative to ePLND, sentinel-node dissection with preoperative isotope injection and imaging has been reported. The objective was to determine whether intraoperative sentinel-node
Introduction: The inspiratory flow pattern influences CO2 elimination by affecting the time the tidal volume remains resident in alveoli. This time is expressed in terms of mean distribution time (MDT), which is the time available for distribution and diffusion of inspired tidal gas within resident alveolar gas. In healthy and sick pigs, abrupt cessation of inspiratory flow (that is, high end-insp
Aim This study investigates inter-annual variability in burnt area in southern Africa and the extent to which climate is responsible for this variation. We compare data from long-term field sites across the region with remotely sensed burnt area data to test whether it is possible to develop a general model. Location Africa south of the equator. Methods Linear mixed effects models were used to det
The amyloid cascade hypothesis on the pathogenesis of Alzheimer's disease (AD) states that amyloid beta (A beta) accumulation in the brain is a key factor that initiates the neurodegenerative process. A beta is generated from amyloid precursor protein (APP) through sequential cleavages by BACE1 (the major beta-secretase in the brain) and gamma-secretase. The purpose of this study was to characteri
A QM/MM investigation of the active-ready (Hox) form of [FeFe]-hydrogenase from D. desulfuricans, in which the electronic properties of all Fe-S clusters (H, F and F') have been simultaneously described using DFT, was carried out with the aim of disclosing a possible interplay between the H-cluster and the accessory iron-sulfur clusters in the initial steps of the catalytic process leading to H2 f
