Background: A novel generation of PET scanners based on silicon (Si)-photomultiplier (PM) technology has recently been introduced. Concurrently, there has been development of new reconstruction methods aimed at increasing the detectability of small lesions without increasing image noise. The combination of new detector technologies and new reconstruction algorithms has been found to increase image

PURPOSE In developing countries, Hodgkin lymphoma (HL) affects the young population. In Ethiopia, nearly 70% of the population are, 35 years of age. Therefore, this study aimed to elucidate the age distribution, histopathologic patterns, clinical characteristics and treatment outcomes of HL in Ethiopia. MATERIALS AND METHODS Data from clinical records of 133 consecutive patients with HL between 20

This article aims to investigate how articulations of women’s relation to the welfare state and modes of political agency has changed in Sweden between 1977 and 2017; a period characterized by the introduction and implementation of a neoliberal political rationality. By way of discourse analysis, the article highlights the reciprocal relationship between the construction of the welfare state and w

Differentiation of the digestive tube and formation of the gut unit as a whole, are regulated by environmental factors through epigenetic modifications which enhance cellular plasticity. The critical period of DNA imprinting lasts from conception until approximately the 1,000th day of human life. During pregnancy, besides agents that may directly promote epigenetic programming (e.g., folate, zinc,

Galectin-1 is a β-galactoside-binding lectin with manifold biological functions. A single tryptophan residue (W68) in its carbohydrate binding site plays a major role in ligand binding and is highly conserved among galectins. To fine tune galectin-1 specificity, we introduced several non-canonical tryptophan analogues at this position of human galectin-1 and analyzed the resulting variants using g

Objective: To summarize the published evidence in the literature on the role of ultrasound and elastography to assess skin involvement in systemic sclerosis (SSc). Methods: A systematic literature review (SLR) was performed within the “Skin Ultrasound Working Group” of the World Scleroderma Foundation, according to the Cochrane Handbook. A search was conducted in Pubmed, Cochrane Library and Embas

Climate change is an existential threat to human survival, the social organization of society, and the stability of ecosystems. It is thereby profoundly frightening. In the face of threat, people often want to protect themselves instead of engaging in mitigating behaviors. When psychological resources are insufficient to cope, people often respond with different forms of denial. In this dissertati

The interplay between innovation and measurement has fascinated scholars from several disciplines over the last decade. All these diverse contributions, however, have resulted in a current state of knowledge that is signified by large numbers of articles without clear integration and synthesis. Therefore the aim of this explorative study is to examine the theoretical notions of innovation and meas

In this work we present a setup for laser-induced breakdown spectroscopy (LIBS) employing a polarization filtering approach and use it for gas diagnostics. A one parts-per-million (ppm) detection sensitivity is achieved for hydrogen atoms.

Hydrogen peroxide (H2O2) is for the first time measured and imaged in two-dimensions in an HCCI engine using photofragmentation laser-induced fluorescence (PF-LIF). Qualitatively, the experimental data agree with simulations.

We present a calibration free technique for spatially resolved imaging of flame temperature. Its application is demonstrated in a low pressure premixed methane flame seeded with indium. Temperature measurements over a range of equivalence ratios are investigated.

The pandemic put all underlying structural problems about the living conditions of older persons in Europe on display. The inadequate protection afforded to older persons during this crisis reflects the weak position of this group. Additionally, the growing ageing population in EU entails an urgent challenge to the union. In this chapter, I argue for what policies the EU needs to implement to ensu

Purpose: Tumor-infiltrating immune cells play a key role in tumor progression. The purpose of this study was to analyze whether the immune infiltrate predicts benefit from postoperative radiotherapy in a large randomized breast cancer radiotherapy trial. Experimental Design: In the SweBCG91RT trial, patients with stage I and II breast cancer were randomized to breast-conserving surgery (BCS) and p

As an adaptive response to hypoxic stress, aggressive tumors rewire their metabolic phenotype into increased malignant behavior through extracellular lipid scavenging and storage in lipid droplets (LD). However, the underlying mechanisms and potential lipid source retrieved in the hypoxic tumor microenvironment remain poorly understood. Here, we show that exosome-like extracellular vesicles (EV),
