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

Nätverk för upptäcksresande studenter tioårsjubilerar

Varje år åker 500 studenter från Lunds Tekniska Högskola och andra europeiska lärosäten över Atlanten för att plugga i Latinamerika och Karibien. Lika många åker åt andra hållet. Utbytet sker inom ramen för nätverket Magalhães – där LTH:s vicerektor Per Warfvinge är ordförande.

Nanoteknik ger snabbare 5G-telefoni

Bättre upplösning på radarbilder och snabbare dataöverföringshastigheter inom 5G-telefoni. Det är några av resultaten som ett nytt forskningsprojekt ska åstadkomma. Projektet går under namnet INSIGHT, är finansierat av EU:s Horizon 2020 och koordineras av Lars-Erik Wernersson, professor i nanoelektronik vid Lunds Tekniska Högskola.

Dynamic changes in the functional anatomy of the human brain during recall of abstract designs related to practice

In the present PET study we explore some functional aspects of the interaction between attentional/control processes and learning/memory processes. The network of brain regions supporting recall of abstract designs were studied in a less practiced and in a well practiced state. The results indicate that automaticity, i.e., a decreased dependence on attentional and working memory resources, develop

Learning-related effects and functional neuroimaging

A fundamental problem in the study of learning is that learning-related changes may be confounded by nonspecific time effects. There are several strategies for handling this problem. This problem may be of greater significance in functional magnetic resonance imaging (fMRI) compared to positron emission tomography (PET). Using the general linear model, we describe, compare, and discuss two approac

Large-scale climatic drivers of regional winter bird population trends

Aim: Changes in climate and land use practices have been found to affect animal populations in different parts of the world. These studies have typically been conducted during the breeding season, whereas the non-breeding season (hereafter ‘winter’) has received much less attention. Changes in regional winter abundances could be caused by changes in overall population sizes and/or redistribution o

Targeted proteomics for the indirect detection of dexamethasone treatment in bovines

The illegal use of pharmacologically active compounds for growth promotion in food-producing species poses risks for consumer health and animal welfare. Surveillance relies on the quantification of drug residues in animal fluids or tissues, but the efficacy can be negatively affected due to undetectable residual concentrations in biological matrices. Consequently, techniques focusing on the indire

FACIN, a double-edged sword of the emerging periodontal pathogen filifactor alocis : A metabolic enzyme moonlighting as a complement inhibitor

Periodontal disease is one of the most common inflammatory infectious diseases worldwide and it is associated with other syndromes, such as cardiovascular disease or rheumatoid arthritis. Recent advances in sequencing allowed for identification of novel periodontopathogens such as Gram-positive Filifactor alocis, but its virulence mechanisms remain largely unknown.We confirmed that F. alocis is a

Development of a moisture safe connection for stud walls

Moisture penetration around windows and doors is a problem with serious consequences for stud walls and is a common problem regardless of facade systems. The problem has received considerable focus in recent times, as buildings using ETICS (External thermal insulation composite systems) on stud walls have been damaged by penetrating water. In the present paper a robust moisture safe prefabricated

Shaping Information Infrastructure Evolution : Governmental Claims of Architectural Control Points

Payments are central for society. Historically, it involved two parties exchanging goods and services for money. Today, payments, with increasing frequency, consist of digital representations of money that are transferred through globally intertwined network. Payments involve many parties such as payers, payment services providers, banks, central banks, telecom operators, mobile handset manufactur

The Revised Sunspot Record in Comparison to Cosmogenic Radionuclide-Based Solar Activity Reconstructions

Recent revisions in the sunspot records illustrate the challenges related to obtaining a 400-year-long observational record of past solar-activity changes. Cosmogenic radionuclides offer the possibility of obtaining an alternative and completely independent record of solar variability. Here, we illustrate that these records offer great potential for quantitative solar-activity reconstructions far

Clonal conversion of B lymphoid leukemia reveals cross-lineage transfer of malignant states

Even though leukemia is considered to be confined to one specific hematopoietic cell type, cases of acute leukemia of ambiguous lineage and patients relapsing in phenotypically altered disease suggest that a malignant state may be transferred between lineages. Because B-cell leukemia is associated with mutations in transcription factors of importance for stable preservation of lineage identity, we

Comparative study of five preoperative methods for the localization of accessory pathways in the Wolff-Parkinson-White syndrome

One hundred and thirty-four cases of Wolff-Parkinson-White syndrome were studied to evaluate the relative usefulness of electrocardiography (ECG), electrophysiological studies (EPS), body surface mapping (BSM), gated blood-pool phase analysis (nuclear studies), and vectorcardiography (VCG) in the localization of the accessory pathway (ACP). In comparison with the final localization verified by int

Parity, breastfeeding and risk of coronary heart disease : A pan-European case-cohort study

Objective There is uncertainty about the direction and magnitude of the associations between parity, breastfeeding and the risk of coronary heart disease (CHD). We examined the separate and combined associations of parity and breastfeeding practices with the incidence of CHD later in life among women in a large, pan-European cohort study. Methods Data were used from European Prospective Investigat

A reference panel of 64,976 haplotypes for genotype imputation

We describe a reference panel of 64,976 human haplotypes at 39,235,157 SNPs constructed using whole-genome sequence data from 20 studies of predominantly European ancestry. Using this resource leads to accurate genotype imputation at minor allele frequencies as low as 0.1% and a large increase in the number of SNPs tested in association studies, and it can help to discover and refine causal loci.
