Kiselalger finns över nästan hela jorden och står för en stor del av jordens samlade fotosyntes. Deras kloroplaster härstammar från rödalger, men resten av deras celler kommer från andra håll. Kiselalgerna har många gener vilkas närmaste släktingar återfinns hos djur, svampar, grönalger eller olika bakterier.

Background: Obesity, type 2 diabetes and atrial fibrillation (AF) are closely associated, but the underlying mechanisms are not fully understood. We aimed to explore associations between body mass index (BMI) or weight change with risk of AF in patients with type 2 diabetes. Methods: A total of 7,169 participations with newly diagnosed type 2 diabetes were stratified according to baseline BMI, and

This article contrasts the intentions and outcomes of the publicly instigated and supported urban renewal of Copenhagen’s Inner Vesterbro district. Apart from physically upgrading the decaying buildings, the municipality’s aim was to include the inhabitants in the urban renewal process and, seemingly, to prevent the dislocation of people from the neighbourhood. However, due to ambiguous policies,

Purpose: The purpose of this study was to assess the alteration of retinal function by multifocal electroretinography and full-field electroretinography in patients with age-related macular degeneration treated with bevacizumab. Methods: We performed a prospective pilot study of 26 eyes of 26 previously treatment-naive patients with neovascular age-related macular degeneration receiving intravitre

An increase in peripheral vascular resistance at rest is not routinely observed in healthy older persons, but often associated with increased stiffness of central elastic arteries, as hallmarks of aging effects on the vasculature, referred to as early vascular aging (EVA). In clinical practice, the increased arterial stiffness translates into increased brachial and central systolic blood pressure

Background: Prediction methods are increasingly used in biosciences to forecast diverse features and characteristics. Binary two-state classifiers are the most common applications. They are usually based on machine learning approaches. For the end user it is often problematic to evaluate the true performance and applicability of computational tools as some knowledge about computer science and stat

Background: A high consumption of fruit and vegetables is possibly associated with a decreased risk of colorectal cancer (CRC). However, the findings to date are inconsistent. Objective: We examined the relation between self-reported usual consumption of fruit and vegetables and the incidence of CRC. Design: In the European Prospective Investigation into Cancer and Nutrition (EPIC), 452,755 subjec

Background: Optimal manual closed chest compressions are difficult to give. A mechanical compression/ decompression device, named LUCAS, is programmed to give compression according to the latest international guidelines (2005) for cardiopulmonary resuscitation (CPR). The aim of the present study was to compare manual CPR with LUCAS-CPR. Methods: 30 kg pigs were anesthetized and intubated. After a

Recent findings show that human fibroblasts can be directly programmed into functional neurons without passing via a proliferative stem cell intermediate. These findings open up the possibility of generating subtype-specific neurons of human origin for therapeutic use from fetal cell, from patients themselves, or from matched donors. In this study, we present an improved system for direct neural c

One of the specific predictions of a new strongly coupled dynamics at a TeV scale is the existence of stable vector-like technibaryon states so that the lightest neutral one could serve as a Dark Matter candidate. We study the latter hypothesis in the QCD-type technicolor with SU (3)(TC) confined group and one SU (2)(W) doublet of vector-like techniquarks consistent with electroweak precision cons

In this thesis, the main male characters in three of the plays written by Federico García Lorca are analysed with the aim of seeing the role they play in the frustration of desire. After two chapters dedicated to a review of published critical studies on Lorca and to certain theoretical considerations, Chapter Three examines desire drawing on Ubersfeld's actancial model and observes that these mal

Slutrapport för projektet Järnet och riksbildningen 1150-1350 (Jernkontort). I uppsatsen diskuteras konsumtion av järn i Bergen och Lödöse baserad på arkeologiskt material. Med utgångspunkt från resultaten görs bl a försök att hypotetiskt bestämma omfattningen av järn totalt i de äldre medeltida städerna i Sverige.

Colorectal cancer (CRC) is a complex disease, and therefore its development is determined by the combination of both environmental factors and genetic variants. Although genome-wide association studies (GWAS) of SNP variation have conveniently identified 20 genetic variants so far, a significant proportion of the observed heritability is yet to be explained. Common copy-number variants (CNVs) are

The aim of the present study is to study the Abscopal regression of subcutaneously implanted N29 rat glioma after immunization with syngeneic IFNg secreting cells and treatment of contra-lateral tumours with pulsed electric fields (PEF) and/or radiation therapy (RT). The study was performed on rats of the Fischer-344 strain with rat glioma N29 tumours implanted subcutaneously on the flank or on bo

Earth-abundant transition-metal complexes are desirable for sensitizers in dye-sensitized solar cells or photocatalysts. Iron is an obvious choice, but the energy level structure of its typical polypyridyl complexes, featuring low-lying metal-centered states, has made such complexes useless as energy converters. Recently, we synthesized a novel iron-N-heterocyclic carbene complex exhibiting a rema

Obesity is globally prevalent and highly heritable, but its underlying genetic factors remain largely elusive. To identify genetic loci for obesity susceptibility, we examined associations between body mass index and similar to 2.8 million SNPs in up to 123,865 individuals with targeted follow up of 42 SNPs in up to 125,931 additional individuals. We confirmed 14 known obesity susceptibility loci

Background Individuals with Anterior Cruciate Ligament (ACL) injury often show altered movement patterns, suggested to be partly due to impaired sensorimotor control. Here, we therefore aimed to assess muscular activity during movements often used in ACL-rehabilitation and to characterize associations between deviations in muscular activity and specific altered movement patterns, using and further

The possibility to study variations in the oxygen isotopic ratio with photon tagged nuclear reaction analysis (pNRA) is evaluated in the current work. The experiment described in the article was performed at Lund Ion Beam Analysis Facility (LIBAF) with a 2 MeV deuteron beam. Isotopic fractionation of light elements such as carbon, oxygen and nitrogen is the basis of many analytical tools in hydrol
