OBJECTIVES: This study examined whether long workhours in combination with an extended workweek (12 hours/7 days), as requested by the workers, impaired attention and cognitive performance and whether the degree of hypothalamic-pituitary-adrenal (HPA) activation was related to the response to the performance tasks. METHODS: A group of 41 male construction workers between 21 and 60 (mean 39) years
INTRODUCTION: D-dimer assays are now widely used as the first-line test in the diagnostic algorithm of suspected deep vein thrombosis (DVT). The aim of this study was to evaluate the performance of two relatively new quantitative D-Dimer assays (Innovance and AxSYM(R)) by comparison with a clinical gold standard. PATIENTS AND METHODS: 311 samples from outpatients with clinical suspicion of DVT, in
The hydrophilic/hydrophobic properties of the membrane material have an important influence on the membrane flux reduction when treating solutions containing hydrophobic solutes. Different methods of measuring the hydrophobic properties of membranes have been evaluated; measurement of the contact angle being the most commonly used method. In this investigation the flux reduction of eight membranes
Greater wax moths (Galleria mellonella L., Pyraloidea) use ultrasound sensitive ears to detect clicking conspecifics and echolocating bats. Pyralid ears have four sensory cells, A14. The audiogram of G. mellonella has best frequency at 60 kHz with a threshold around 47 dB sound pressure level. A1 and A2 have almost equal thresholds in contrast to noctuids and geometrids. A3 responds at + 12 to + 1
Purpose: Packaging adds weight and volume to food products, thereby increasing the environmental impact of transport processes. This research examines the relative importance of transport efficient packaging in food supply chains that rely on road transport compared to other environmental requirements, such as packaging material minimization and food waste reduction.Design/methodology/approach: Sc
Semiconductor nanowire (NW) solar cells with a single p-n junction have exhibited efficiency comparable to that of their planar counterparts with a substantial reduction in material consumption. Tandem geometry is a path toward the fabrication of devices with even higher efficiencies, for which a key step is the fabrication of tunnel (Esaki) diodes within NWs with the correct diameter, pitch, and
The causes and extent of regional inequality in the process of economic growth are at the core of historical economic research. So far, much attention has been devoted to studying the role of industrialization in driving regional divergence. But empirical studies on relatively unequal countries such as Italy or Spain show that inequality was already high when their modern industrialization began (
INTRODUCTION: The indication for breast reduction in a public welfare or an insurance paid setting depends on the severity of the subjective symptoms and the clinical evaluation. The purpose of this study was to evaluate the use of breast volume as an objective criterion to establish the indication for breast reduction surgery, thus establishing a standard decision basis that can be shared by surg
Despite an abundance of peptides inside a cell, only a small fraction is ultimately presented by HLA-I on the cell surface. The presented peptides have HLA-I allomorph-specific motifs and are restricted in length. So far, detailed length studies have been limited to few allomorphs. Peptide-HLA-I (pHLA-I) complexes of different allomorphs are qualitatively and quantitatively influenced by tapasin t
Over 50 million people worldwide have epilepsy. In nearly 30% of these cases, epilepsy remains unsatisfactorily controlled despite the availability of over 20 antiepileptic drugs. Moreover, no treatments exist to prevent the development of epilepsy in those at risk, despite an increasing understanding of the underlying molecular and cellular pathways. One of the major factors that have impeded rap
PurposeThe purpose of this paper is to differentiate human responses to different light switch designs to determine the effects of these common interfaces on user perceptions and use of electric lighting in public buildings.Design/methodology/approachEmpirical studies were conducted to assess and examine user perceptions with regard to design characteristics of light switches, and occupants’ use o
Cell replacement therapy in Parkinson’s disease (PD) still lacks a study addressing the acquisition of electrophysiological properties of human grafted neural stem cells and their relation with the emergence of behavioral recovery after transplantation in the short term. Here we study the electrophysiological and biochemical profiles of two ventral mesencephalic human neural stem cell (NSC) clonal
In this work, extraction and characterization of compounds with antioxidant and antimicrobial activity from Haematococcus pluvialis microalga in red phase have been carried out. To do this, subcritical water extraction (SWE) has been combined with analytical techniques such as HPLC-DAD, HPLC-QqQ-MS and GC-MS and in vitro assays (i.e., for antioxidant and antimicrobial activity). The effect of the
Packaging innovation is a strategic and valuable tool yet underexplored in business and extended value chains. Demographic changes, as population aging, and the increase of healthcare costs pose challenges and opportunities for the pharmaceutical industry, where packaging innovation offers new opportunities to provide patients with better solutions. This study employs a multi-stakeholder perspecti
Research funding is essential for promoting internationalization of science, technology and innovation. It is a key mechanism to advance international science, technology and innovation (STI) cooperation. This thesis argues that funding is a dominant driver of internationalization of science, technology and innovation but it is viewed as less than an optimal mechanism because of the trade-offs and
In the context of the COVID-19 pandemic, governments worldwide face the challenge of designing tailored measures of epidemic control to provide reliable health protection while allowing societal and economic activity. In this paper, we propose an extension of the epidemiological SEIR model to enable a detailed analysis of commonly discussed tailored measures of epidemic control—among them group-sp
Viral etiology of nasal polyps was postulated as many as 40 years ago, but so far, no study has shown an association or causal relation between any specific virus and nasal polyps. By using the polymerase chain reaction (PCR) technique, nasal polyps from both 10 patients with intolerance to nonsteroidal anti-inflammatory drugs (NSAID intolerance) (e.g., Aspirin) and from 10 patients with no histor
Penalty kicks in soccer provide a unique scenario in which to examine human choice behavior under competitive conditions. Here, we report two studies examining the tendency for soccer kickers to select the goal side with the largest area to the left or right of the goalkeeper’s veridical midline, when the goalkeeper stands marginally off-center. In Study I participants viewed realistic images of a
