Caries risk assessment in young adults: A 3-year validation of clinical guidelines used in Public Dental Service

Objectives. To validate a risk classification model according to the Public Dental Service (PDS) guidelines with the actual 3-year caries outcome in terms of predictive values. Materials and methods. All 19-year-old patients registered at eight public dental clinics in Skane, Sweden were invited to participate (n = 1699). The study group who completed the baseline examination consisted of 1295 sub

A plant factory for moth pheromone production

Moths depend on pheromone communication for mate finding and synthetic pheromones are used for monitoring or disruption of pheromone communication in pest insects. Here we produce moth sex pheromone, using Nicotiana benthamiana as a plant factory, by transient expression of up to four genes coding for consecutive biosynthetic steps. We specifically produce multicomponent sex pheromones for two spe

TRPA1 Contributes to the Acute Inflammatory Response and Mediates Carrageenan-Induced Paw Edema in the Mouse

Transient receptor potential ankyrin 1 (TRPA1) is an ion channel involved in thermosensation and nociception. TRPA1 is activated by exogenous irritants and also by oxidants formed in inflammatory reactions. However, our understanding of its role in inflammation is limited. Here, we tested the hypothesis that TRPA1 is involved in acute inflammatory edema. The TRPA1 agonist allyl isothiocyanate (AIT

Hypoxia-driven variations in iron and manganese shuttling in the Baltic Sea over the past 8 kyr

The Baltic Sea has experienced three major intervals of bottom water hypoxia following the intrusion of seawater circa 8 kyr ago. These intervals occurred during the Holocene Thermal Maximum (HTM), Medieval Climate Anomaly (MCA), and during recent decades. Here we show that sequestration of both Fe and Mn in Baltic Sea sediments generally increases with water depth, and we attribute this to shelf-

Sub-attomolar detection of cholera toxin using a label-free capacitive immunosensor

A label-free immunosensor for the direct detection of cholera toxin (CT) at sub-attomolar level has been developed based on potential-step capacitance measurements. Anti-CT antibody was adsorbed on gold nanoparticles (AuNPs) incorporated on a polytyramine-modified gold electrode. The concentration of CT was determined by detecting the change of capacitance caused by the formation of antibody-antig

Cognitive and linguistic skills in Swedish children with cochlear implants - measures of accuracy and latency as indicators of development

Wass, M., Ibertsson, T., Lyxell, B., Sahlen, B., Hallgren, M., Larsby, B. & Maki-Torkko, E. (2008). Cognitive and linguistic skills in Swedish children with cochlear implants - measures of accuracy and latency as indicators of development. Scandinavian Journal of Psychology. The purpose of the present study was to examine working memory (WM) capacity, lexical access and phonological skills in

Tipping Elements in the Arctic Marine Ecosystem

The Arctic marine ecosystem contains multiple elements that present alternative states. The most obvious of which is an Arctic Ocean largely covered by an ice sheet in summer versus one largely devoid of such cover. Ecosystems under pressure typically shift between such alternative states in an abrupt, rather than smooth manner, with the level of forcing required for shifting this status termed th

Harmonic morphisms from homogeneous Hadamard manifolds

We present a new method for manufacturing complex-valued harmonic morphisms from a wide class of Riemannian Lie groups. This yields new solutions from an important family of homogeneous Hadamard manifolds. We also give a new method for constructing left-invariant foliations on a large class of Lie groups producing harmonic morphisms.

Same Business Same System?: A Critique of organization and the information systems process.

In trying to understand any aspect surrounding the success and failure of information systems (IS) practice, concepts of organizational analysis become increasingly important. Many issues arise and must be dealt with when an information system is to be developed and implemented. In order to avoid information system failures, information system analysts should adopt an approach that exploits the in

Grain-128a: a new version of Grain-128 with optional authentication

A new version of the stream cipher Grain-128 is proposed. The new version, Grain-128a, is strengthened against all known attacks and observations on the original Grain-128, and has built-in support for optional authentication. The changes are modest, keeping the basic structure of Grain-128. This gives a high confidence in Grain-128a and allows for easy updating of existing implementations.

Finding a heaviest vertex-weighted triangle is not harder than matrix multiplication

We show that a maximum-weight triangle in an undirected graph with n vertices and real weights assigned to vertices can be found in time O(n(omega) + n(2+o(1))), where omega is the exponent of the fastest matrix multiplication algorithm. By the currently best bound on omega, the running time of our algorithm is O(n(2.376)). Our algorithm substantially improves the previous time-bounds for this pro

A Tool to Evaluate Different Renovation Alternatives with Regard to Sustainability

In Sweden and in other countries, building owners are encouraged to help reduce energy consumption, both in order to contribute to national energy saving goals and, in terms of their own interests, to reduce the costs of heating and operation of the building. However, it is important to pursue the most optimal strategy available so as to achieve cost-effective energy usage while simultaneously mai

First chelonian eggs and carapace fragments from the Pliocene of Rhodes, Greece

Well-preserved fossil eggs and eggshell fragments from the Pliocene Apolakkia Formation of Rhodes (Greece) are described. The eggs were found in-situ in a clutch. They are sub- spherical with lengths of 53-60 mm and widths of about 40 mm. All eggs are diagenetically compressed and their original diameters are estimated at 45-50 mm. The eggshells are 0.3-0.5 mm thick, partly re-crystallized, but wi

The prevalence of moderate to severe radiographic sacroiliitis and the correlation with health status in elderly Swedish men - The MrOS study.

Ankylosing Spondylitis (AS) is a chronic inflammatory disease with onset in young adults, but little is known about the prevalence in older age groups. Furthermore, there is very limited information of health status of elderly patients with AS. Our objective was to estimate the prevalence of moderate to severe radiographic sacroiliitis in elderly men and its impact on health.

Implicit prejudice and ethnic minorities: Arab-Muslims in Sweden

Purpose – The aim of this paper is to examine whether Swedish employers implicitly/automatically hold negative attitudes toward Arab-Muslims, an ethnic minority group subjected to substantial labor market discrimination in Sweden and, more specifically, associate members of this minority group with lower work productivity, as compared with native Swedes.
