On the Role of the Rank Condition in CCE Estimation of Factor-Augmented Panel Regressions
A popular approach to factor-augmented panel regressions is the common correlatedeffects (CCE) estimator of Pesaran (Estimation and inference in large heterogeneous panels with a multifactor error structure. Econometrica 74, 967–1012, 2006). This paper points to a problem with the CCE approach that appears in the empirically relevant case when the number of factors is strictly less than the number
Radiotherapy induces an immediate inflammatory reaction in malignant glioma : a clinical microdialysis study
The knowledge of response to radiation in the immuno-microenvironment of high grade gliomas is sparse. In vitro results have indicated an inflammatory response of myeloid cells after irradiation. Therefore, microdialysis was used to verify whether this is operative in tumor tissue and brain adjacent to tumor (BAT) after clinical radiotherapy of patients with high grade glioma. Stereotactic biopsie
Outcome of the Swedish Nationwide abdominal aortic aneurysm screening program
Background: A general abdominal aortic aneurysm (AAA) screening program, targeting 65-year-old men, has gradually been introduced in Sweden since 2006 and reached nationwide coverage in 2015. The aim of this study was to determine the outcome of this program. Methods: Data on the number of invited and examined men, screening-detected AAAs, AAAs operated on, and surgical outcome were retrieved from
N-terminal prosomatostatin as a risk marker for cardiovascular disease and diabetes in a general population
Context: Somatostatin inhibits a range of hormones, including GH, insulin, and glucagon, but little is known about its role in the development of cardiometabolic disease. Objective: The objective of the study was to investigate whether fasting plasma concentration of N-terminal prosomatostatin (NT-proSST) is associated with the development of diabetes, coronary artery disease (CAD), and mortality.
Lateralized frontal blood flow increases during fluency tasks : influence of cognitive strategy
Difficulties with verbal fluency tasks (VFIT) have been shown mainly to be associated with left frontal lobe pathology in lesion studies. The design fluency test (DFT) is a non-verbal analogue of word fluency tasks and has, in patients with right frontal lobe pathology, been coupled to an inability to perform well. Regional cerebral blood flow measurements (rCBF) were made in normals to elucidate
The Formation of the ’Book’ of Psalms : Reconsidering the Transmission and Canonization of Psalmody in Light of Material Culture and the Poetics of Anthologies
By conceptualizing the ‘Book' of Psalms as an anthology, and by inquiring into its poetics by means of paratextuality, David Willgren provides a fresh reconstruction of its formation and concludes that it preserves a selection of psalms that is best seen not as a book of psalms, but as a canon of psalms.
Early ontogeny of the Furongian (Cambrian) olenid trilobites Sphaerophthalmus alatus (Boeck, 1838) and Ctenopyge (Mesoctenopyge) tumida Westergård, 1922 from Bornholm, Denmark
The early stages in ontogenetic development are described in the co-occurring Sphaerophthalmus alatus (Boeck, 1838) and Ctenopyge (Mesoctenopyge) tumida Westergård, 1922, using fragmentary but otherwise well-preserved material from Bornholm, Denmark. The former species is a senior synonym of Ctenopyge (Eoctenopyge) angusta Westergård, 1922, as has been recently proposed, but the early stages of S.
Cancer-associated fibroblast-secreted CXCL16 attracts monocytes to promote stroma activation in triple-negative breast cancers
Triple-negative (TN) breast cancers (ER â ' PR â ' HER2 â ') are highly metastatic and associated with poor prognosis. Within this subtype, invasive, stroma-rich tumours with infiltration of inflammatory cells are even more aggressive. The effect of myeloid cells on reactive stroma formation in TN breast cancer is largely unknown. Here, we show that primary human monocytes have a survival advantag
Rehabilitation of masonry facades damaged by reinforcement corrosion
This paper presents results from a project dealing with rehabilitation of clay brick facades damaged by reinforcement corrosion. Based on laboratory tests and results from pilot projects, practical recommendations for appropriate removal of bed joint reinforcement and repair of joints are issued for facility owners, contractors and designers.
Green and blue water demand from large-scale land acquisitions in Africa
In the last decade, more than 22 million ha of land have been contracted to large-scale land acquisitions in Africa, leading to increased pressures, competition, and conflicts over freshwater resources. Currently, 3% of contracted land is in production, for which we model site-specific water demands to indicate where freshwater appropriation might pose high socioenvironmental challenges. We use th
Venous thromboembolism with special focus on genetic and potential acquired risk factors
Venous thromboembolism (VTE) is a relatively common cause of morbidity and mortality. It has an annual incidence of around 0.1- 0.3%. It is a multifactorial disease with many known risk factors, both transient and persistent. Among these, several genetic risk factors have been described. The most common genetic risk factor, factor V Leiden mutation in heterozygote form, is found in 5-8% of the Cau
Light use efficiency of peatlands: Variability and suitability for modeling ecosystem production
Peatland net ecosystem production is a key variable to assess changes in the functional role of peatlands in the global carbon cycle. Light use efficiency (LUE) models in combination with satellite data have been used to estimate production for most major ecosystems, but peatlands have been largely ignored. The objectives of this study were: 1) to examine how the LUE parameter epsilon, ε (the amou
Prevalence and genetic and environmental influences on anxiety disorders in 6-year-old twins
Background. Prevalence of childhood anxiety disorders at specific ages and genetic etiological influences on anxiety disorders in young children have been little studied. The present study reports prevalence estimates in a community sample of 6-year-old twins, and patterns of genetic and environmental influences on these early-onset anxiety disorders. Method. Using a two-phase design 4662 twin-pai
A twin study of anxiety-related behaviours in pre-school children
Background: From middle childhood onwards, substantial evidence points to phenotypic differentiation between anxiety diagnostic categories such as generalised anxiety, separation anxiety, specific phobia, and obsessive-compulsive disorders. However, little is known about the genetics of these categories and especially about the phenotypic and genetic structure of related behaviours in pre-school c
The potential for faking on the Mississippi Scale for Combat-Related PTSD
The Mississippi Scale for Combat-Related PTSD is widely used in the assessment of post-traumatic stress disorder (PTSD). The high face-validity of the scale may make it vulnerable to faking however. The present study found that the scores of individuals instructed to respond 'as if' they had PTSD did not differ from the scores of veterans with PTSD. Furthermore, although veterans who were diagnose
Further validation of the Chronic Pain Values Inventory in a Swedish chronic pain sample
PurposeValue based action is an important process in the psychological flexibility model and is associated with daily functioning in people with chronic pain, but measures of it are not well-developed. The purpose of the present study was to examine the reliability and validity of a Swedish-language version of the Chronic Pain Values Inventory (CPVI) in a large sample of adults seeking treatment f

Historical experience (1850–1950 and 1961–2014) of insect species responsible for forest damage in Sweden : Influence of climate and land management changes
The ongoing climate change can influence the dynamic of insect populations and therefore the Insect species Responsible for Forest Damage (“insects-RFD” hereafter). The present study aims at identifying the most occurring insects-RFD in Sweden, and exploring the relationships between insects-RFD and climate and land management changes. The recorded insect attacks based on historical reports, liter
Real-time monitoring of the sugar sensing in Saccharomyces cerevisiae indicates endogenous mechanisms for xylose signaling
The sugar sensing and carbon catabolite repression in Baker’s yeast Saccharomyces cerevisiae is governed by three major signaling pathways that connect carbon source recognition with transcriptional regulation. Here we present a screening method based on a non-invasive in vivo reporter system for real-time, single-cell screening of the sugar signaling state in S. cerevisiae in response to changing
