Glycaemic Response in Relation to Gastric Emptying and Satiety in Health and Disease

Dietary fibre and whole grains are recommended to prevent the development of type 2 diabetes. Low glycaemic index foods that are rich in fibre are recommended to control blood glucose levels. Gastric emptying, together with other factors, regulate the postprandial blood glucose response. A delay in the gastric emptying rate (GER) leads to a lower postprandial blood glucose concentration. However,

PKA-induced phosphorylation of ER alpha at serine 305 and high PAK1 levels is associated with sensitivity to tamoxifen in ER-positive breast cancer

Phosphorylation of estrogen receptor alpha at serine 305 (ER alpha S305-P) by protein kinase A (PKA) or p21-activated kinase 1 (PAK1) has experimentally been associated with tamoxifen sensitivity. Here, we investigated the clinical application of this knowledge to predict tamoxifen resistance in ER-positive breast cancer patients. Using immunohistochemistry, a score including PAK1 and co-expressio

Environmental Toxins and Essential Trace Elements at Delivery and ADHD

Popular Abstract in Swedish Sambandet mellan exponering för miljögifter och mineraler i fosterlivet och risken att ha ADHD diagnos i barndomen ADHD (uppmärksamhetsstörning med hyperaktivitet) är en neuropsykiatrisk funktionsnedsättning som drabbar barn och kan fortsätta till vuxen ålder. Antalet barn som diagnosticerats med ADHD har ökat under senare år. Om detta beror på att man fått mer kunskapPerfluorinated compounds (PFCs), phthalates, manganese and selenium are ubiquitous in the environment and humans and influence fetal growth and development. Register and biobank based case-control studies were conducted to investigate the relationship between prenatal exposure to these chemicals and attention deficit hyperactivity disorder (ADHD) in childhood. The study base comprised children bo

Alpha-Synuclein Expression in the Oligodendrocyte Lineage: an In Vitro and In Vivo Study Using Rodent and Human Models.

In this study, we sought evidence for alpha-synuclein (ASYN) expression in oligodendrocytes, as a possible endogenous source of ASYN to explain its presence in glial inclusions found in multiple system atrophy (MSA) and Parkinson's disease (PD). We identified ASYN in oligodendrocyte lineage progenitors isolated from the rodent brain, in oligodendrocytes generated from embryonic stem cells, and in

Recurrent chromosome 22 deletions in osteoblastoma affect inhibitors of the wnt/beta-catenin signaling pathway.

Osteoblastoma is a bone forming tumor with histological features highly similar to osteoid osteoma; the discrimination between the tumor types is based on size and growth pattern. The vast majority of osteoblastomas are benign but there is a group of so-called aggressive osteoblastomas that can be diagnostically challenging at the histopathological level. The genetic aberrations required for osteo

Studies of the pathogenesis of Shiga toxin-producing Escherichia coli-induced hemolytic uremic syndrome

Popular Abstract in Swedish Enterohemorragisk Escherichia coli (EHEC) EHEC är mycket virulent för människor, det räcker med så få som 50-100 bakterier för att man ska bli infekterad och utveckla symtom. Varje år rapporteras ca 300-500 fall av EHEC smitta i Sverige. Den stam som oftast isoleras från patienter är E. coli O157:H7. Reservoarer för EHEC är idisslare och framförallt kor. Kor är nämligHemolytic uremic syndrome (HUS) is characterized by non-immune hemolytic anemia, thrombocytopenia and acute kidney failure. The most common form of HUS is associated with gastrointestinal Shiga toxin-producing enterohemorrhagic Escherichia coli (EHEC) infection. EHEC are non-invasive strains with Shiga toxin as the unique virulence factor. The aim of this study was to describe host-pathogen intera

Waiting Places as Temporal Interstices and Agents of Change

One of the main ways in which in-between time-spaces are organised and materialised in the urban environment is through waiting places. In his article we point to the transformative potential of waiting places, their role as actors in an urban web, and discuss briefly their societal role in recent historical changes. Public waiting places are today increasingly becoming pre-programmed: connected t

Trivacancy-oxygen complex in silicon: Local vibrational mode characterization

FTIR study of the evolution of multivacancy-oxygen-related defects in the temperature range 100-350 degrees C in Czochralski-grown Si samples irradiated with different particles (10 MeV electrons and 5 MeV neutrons) has been carried out. Appearance of two absorption bands positioned at 833.4 and 842.4 cm(-1) has been found upon annealing of the divacancy related absorption band at 2767 cm(-1). The

beta-delayed gamma-ray spectroscopy of Au-203,Au-204 and Pt200-202

The beta decay of five heavy, neutron-rich nuclei, Pt-203,Pt-204 and Ir200-202, has been investigated following relativistic cold fragmentation reactions of lead projectiles using the FRS + RISING setup at GSI. This paper reports on the study of the low-lying states in the decay daughter nuclei Au-203,Au-204 and Pt200-202. The characteristic gamma rays for each nucleus have been determined using b

Taming killer cells may halt diabetes progression

Preclinical studies in mice suggest that the natural killer cell receptor NKp46 may be a new molecular target for delaying the progression of type 1 diabetes by interfering with unexpected natural killer cell-mediated recognition of pancreatic beta cells.

Migratory and resident blue tits Cyanistes caeruleus differ in their reaction to a novel object

Individuals differ consistently in their behavioural reactions towards novel objects and new situations. Reaction to novelty is one part of a suit of individually consistent behaviours called coping strategies or personalities and is often summarised as bold or shy behaviour. Coping strategies could be particularly important for migrating birds exposed to novel environments on their journeys. We c

Experiences from the production and homogeneity analysis of an AMS 14C sucrose standard for high-activity measurements

Accurate accelerator mass spectrometry (AMS) measurements rely on standards with well-known isotopic ratios. For radiocarbon measurements, a number of standards with different properties are commercially available, of which the IAEA-C6 sucrose standard with a 14C value of 150.61 pMC is the most active. When analyzing biological samples resulting from studies using 14C-labeled substances, the activ

CD4(+)T cells do not mediate within-host competition between genetically diverse malaria parasites

Ecological interactions between microparasite populations in the same host are an important source of selection on pathogen traits such as virulence and drug resistance. In the rodent malaria model Plasmodium chabaudi in laboratory mice, parasites that are more virulent can competitively suppress less virulent parasites in mixed infections. There is evidence that some of this suppression is due to

S100B levels are affected by older age but not by alcohol intoxication following mild traumatic brain injury

Introduction: Biomarkers of brain damage and head injury are potentially useful tools in the management of afflicted patients. Particularly S100B has received much attention and has been adapted into clinical guidelines. Alcohol intoxication and higher age (65 years and over) have been used as risk factors for serious complications following head injury. The effect of these factors on S100B levels

Democracy in Global Governance: The Promises and Pitfalls of Transnational Actors

The participation of transnational actors in global policymaking is increasingly seen as a means to democratize global governance. Drawing on alternative theories of democracy and existing empirical evidence, we assess the promises and pitfalls of this vision. We explore how the structuring and operation of international institutions, public-private partnerships, and transnational actors themselve

Hyperfine induced intensity redistribution in In II

We present a theoretical investigation of the hyperfine structure of the 5s5d D-3(2)-5s4f F-3(2,3)0 transitions in In II. Earlier work has failed in determining hyperfine constants for the upper levels of these transitions. We show that this is due to strong off-diagonal hyperfine interaction, which not only changes the position of the individual hyperfine lines but also introduces large intensity

Non-Invasive Estimates of Left Atrial Activation in a Patient with Dissociated Left Atrial Tachycardia following Ablation of Atrial Fibrillation

Introduction: Interatrial frequency gradient is used to guide catheter ablation of atrial fibrillation (AF) but reliable tools for its non-invasive estimation are lacking. We present a patient with dissociated left and right atrial rhythms that allows identification of sum face ECG leads that closely reflect left atrial activity. Methods: 12-lead ECG was recorded simultaneously with electrograms f

New insights into the development of retinopathy of prematurity - importance of early weight gain

Evidence is accumulating that one of the strongest predictors of retinopathy of prematurity (ROP), in addition to low gestational age, is poor weight gain during the first weeks of life. In infants born preterm, the retina is not fully vascularised. The more premature the child, the larger is the avascular area. In response to hypoxia, vascular endothelial growth factor (VEGF) is secreted. For app
