Prognostic factors in lumbar spinal stenosis surgery. A prospective study of imaging- and patient-related factors in 109 patients who were operated on by decompression

Background and purpose A considerable number of patients who undergo surgery for spinal stenosis have residual symptoms and inferior function and health-related quality of life after surgery. There have been few studies on factors that may predict outcome. We tried to find predictors of outcome in surgery for spinal stenosis using patient- and imaging-related factors. Patients and methods 109 pati

Sustainability objects as performative definitions of sustainability: The case of food waste-based biogas and biofertilizers

This article introduces the notion of sustainability objects to label objects that come with a claim to promote a more sustainable mode of living. The purpose is to show that organizations that develop such objects contribute to defining sustainability. A case study of the development of a food waste-based biogas and biofertilizers production facility serves as empirical example of sustainability

Direct association between diet and the stability of human atherosclerotic plaque.

Mediterranean diet has been suggested to explain why coronary heart disease mortality is lower in southern than northern Europe. Dietary habits can be revealed by isotope ratio mass spectrometry (IRMS) measurement of carbon (δ(13)C) and nitrogen (δ(15)N) in biological tissues. To study if diet is associated with human plaque stability, atherosclerotic plaques from carotid endarterectomy on 56 pati

Exkludering, assimilering eller utrotning? : "Tattarfrågan" i svensk politik 1880-1955

Hösten 1943 genomförde Socialstyrelsen rasbiologiska mätningar av mer än hundra svenskar som myndigheten ansåg var ”tattare”, däribland flera barn. Genom att mäta längden på näsor, armar och pannor ville myndigheten få fram ett objektivt sätt att avgöra vilka svenskar som borde kategoriseras på detta sätt. Målet var att skapa särskilda politiska åtgärder mot gruppen, som länge givits skulden för eSince the 16th Century, there has been Travelling families in Sweden, earning their living by itinerant trades such as horse-trading, scrap-metal-dealing and tinplating. The authorities often labelled these families “tattare”. They suffered from severe discrimination, and authorities as well as scientists claimed that they were a threat against society. These claims were often made with a racializ

The relationship between deferred imitation, associative memory and communication in 14-month-old children. Behavioral and electrophysiological indices

Abstract in UndeterminedThe present study combines behavioral observations of memory (deferred imitation, DI, after a brief delay of 30 min and after a long delay of 2-3 weeks) and electrophysiological (event-related potentials, ERPs) measures of associative memory, as well as parental reports of non-verbal and verbal communication in sixteen 14-months-old children. Results show that for DI, the c

Ecosystem functional assessment based on the "optical type" concept and self-similarity patterns: An application using MODIS-NDVI time series autocorrelation

Remote sensing (RS) time series are an excellent operative source for information about the land surface across several scales and different levels of landscape heterogeneity. Ustin and Gamon (2010) proposed the new concept of "optical types" (OT), meaning "optically distinguishable functional types", as a way to better understand remote sensing signals related to the actual functional behavior of

Why is the shark not an animal? On the Division of life-form categories in Oceania

In Oceania, there is a strong linguistic link between terms for marine resource exploitation and the division of life forms. Aspects of this relationship (especially in Cook Islands and Tonga) are described and discussed in this paper from a cross-cultural perspective. A Polynesian response to the question of why the shark is not an animal shows that modern science, which is a "science of the abst

Flow-Through-Mediated Surface Immobilization of Sub-Micrometre Particles in Monolithic Cryogels

Particles with functional groups on their surface were immobilized on premade cryogels through covalent bonding to maximize the accessibility of the target molecules to the surface of the particles. The physical properties of the composite cryogel were characterized by SEM, texture analysis and nitrogen adsorption. Different key factors affecting immobilization were also investigated, e.g., recirc

Women in evolution - highlighting the changing face of evolutionary biology

The face of science has changed. Women now feature alongside men at the forefront of many fields, and this is particularly true in evolutionary biology. This special issue celebrates the outstanding achievements and contributions of women in evolutionary biology, by highlighting a sample of their research and accomplishments. In addition to original research contributions, this collection of artic

Does DNA Methylation of PPARGC1A Influence Insulin Action in First Degree Relatives of Patients with Type 2 Diabetes?

Epigenetics may play a role in the pathophysiology of type 2 diabetes (T2D), and increased DNA methylation of the metabolic master regulator peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PPARGC1A) has been reported in muscle and pancreatic islets from T2D patients and in muscle from individuals at risk of T2D. This study aimed to investigate DNA promoter methylation and gen

Validation of digital photographs, as a tool in 24-h recall, for the improvement of dietary assessment among rural populations in developing countries

BackgroundImprovement of traditional methods for dietary assessment is necessary, especially in rural areas where it is more difficult to succeed with self-reporting methods. This study presents and validates a method for improving accuracy when measuring food and nutrient intake of individuals in rural areas. It is called the “Food photography 24-h recall method” (FP 24-hR) and is a modified

Acute right ventricular failure caused by concomitant coronary and pulmonary embolism: successful treatment with endovascular coronary and pulmonary thrombectomy.

Patent foramen ovale (PFO) is present in approximately 25% of the general population. PFO is characterized by intermittent shunting of blood from the right to the left atrium, especially in the context of increased right-sided filling pressures, with risk of paradoxical embolism. We describe a 69-year-old woman presenting with acute chest pain, severe dyspnoea, and acute inferolateral ST-segment e

Pulse pressure strongly predicts cardiovascular disease risk in patients with type 2 diabetes from the Swedish National Diabetes Register (NDR).

OBJECTIVES: To analyze pulse pressure (PP) as a risk predictor for coronary heart disease (CHD), stroke and cardiovascular disease (CVD; CHD and/or stroke) in type 2 diabetic patients. METHODS: A total of 11,128 female and male type 2 diabetic patients with known baseline PP values and no CVD, aged 50-74 years, were followed for a mean duration of 5.6 years (1998-2003). A subgroup of 5521 patients
