Estrogen receptor content in adenovirus type 9-induced rat mammary tumors

Hormonal factors play an important role in the induction of mammary tumors and tumor-like lesions in adenovirus type 9-inoculated W/Fu rats. Primary Ad 9-induced fibroadenomas contained significantly higher amounts of estrogen receptor (determined by means of enzyme immunoassay) in comparison to normal breast tissue (p = 0.01**) and 'spontaneous' fibroadenomas (p = 0.03*), used as control tissues.

Towards a two-part train traffic emissions factor model for airborne wear particles

In 2017 a new railway tunnel containing two stations opened in Stockholm, Sweden. A series of field measurements were carried out on the platforms in this tunnel before and after it was opened for normal traffic. These measurements were used to investigate the contribution of airborne particle emissions from wear processes to total train emissions. This field data was used to develop a two-part tr

A concept for reducing PM10 emissions for car brakes by 50%

With regard to airborne particles with an aerodynamic diameter of less than 10 µm (PM10), in countries in the European Union, the mass of brake emissions equals approximately 8–27% of the total traffic-related emissions. Using a research methodology combining tests at different scale levels with contact mechanics simulations and PM10 chemical characterization, the REBRAKE EU-financed project had t

The tribological efficiency and the mechanism of action of nano-porous composition base brake lining materials

Based on the comparative analysis of the experimental values determined for the tribological parameters for the three novel nano-porous composition base and two conventional brake lining materials while friction with the grey cast iron disc, it was shown the considerable high tribological efficiency of the novel nano-porous composition base lining materials in comparison with the conventional (fro

A cellular automaton approach to numerically simulate the contact situation in disc brakes

Since brake wear is an important contributor to the concentration of airborne particles in urban atmospheres, it is important to increase our understanding of the origin of these particles. The contact situation between the pad and disc is complicated. Metal fibres in the pad (or other hard materials) form stable contact plateaus, which carry the main part of the load. A flow of wear particles in

Tissue kallikrein in severe acute pancreatitis in patients treated with high-dose intraperitoneal aprotinin

The activation of the kallikrein-kinin system is thought to be one of the pathophysiologic mechanisms in acute pancreatitis. A radioimmunoassay for human urinary tissue kallikrein was developed and used to measure tissue kallikrein peritoneal exudate and plasma from 48 patients with severe acute pancreatitis. All patients were treated with intraperitoneal lavage. One group (n = 22) received high d

Meanings of being critically ill in a sound-intensive ICU patient room -A phenomenological hermeneutical study

The aim of this study was to illuminate the meanings of being critically ill in a sound-intensive ICU patient room, as disclosed through patients' narratives. Patient rooms in ICUs are filled with loud activity and studies have revealed sound levels comparable to those of a busy road above the patient's head. There is a risk that the sound or noise is disturbing and at worst a major problem for th

Advanced Optical Diagnostics in Particle Combustion for Biomass and Metal as Alternative Fuels

The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. Biomass is a renewable and carbon-neutral energy source that provides heat and power through gasification and combustion. Biomas

Trajectory Generation for Assembly Tasks via Bilateral Teleoperation

For assembly tasks, the knowledge of both trajectory and forces are usually required. Consequently, we may use kinesthetics or teleoperation for recording human demonstrations. In order to have a more natural interaction, the operator has to be provided with a sense of touch. We propose a bilateral teleoperation system which is customized for this purpose. We introduce different coordinate frames

Systems with Massive Number of Antennas: Distributed Approaches

As 5G is entering maturity, the research interest has shifted towards 6G, and specially the new use cases that the future telecommunication infrastructure needs to support. These new use cases encompass much higher requirements, specifically: higher communication data-rates, larger number of users, higher accuracy in localization, possibility to wirelessly charge devices, among others.The radio ac

Poor intake of vitamins and minerals is associated with symptoms among patients with irritable bowel syndrome

Background and Aim: Poor food habits with insufficient intake of micronutrients have been described in irritable bowel syndrome (IBS), which could be of importance for development of gastrointestinal and extraintestinal symptoms. The study aims were to examine intake and plasma/serum levels of micronutrients in IBS and whether these factors were associated with symptoms and restrictions and to stu

Risk Factors for Complicated Mohs Surgery in the South Sweden Mohs Cohort

Background: Mohs micrographic surgery (MMS) is a precise, tissue-sparing surgical technique that offers superior cure rates compared to traditional surgical excision. However, the degree of difficulty of MMS depends on many variables, and consequently, the number of surgical stages required for each case is quite unpredictable.Objectives: To identify risk factors for complicated MMS, defined as MM

Did it pay to be a pioneer? Wealth accumulation in a newly settled frontier society

European settler colonies are often thought to have been characterized by a continued expansion of the landed frontier, which impacted the distribution of wealth across their settler populations. Hampered by a lack of data, few studies have been able to study this in-depth. How does settlement timing affect wealth and wealth accumulation when frontier expansion is not a smooth continuous process?

Revisiting the green geographies of welfare planning : an introduction

he history and legacy of green planning of the welfare era have largely been overlooked within research, or critiqued due to its limited urban qualities and poor design. This omission has left its role in the development of the Welfare society largely unexplored. Therefore, this special issue revisits the green geographies of welfare planning, to reveal its importance as a matter of welfare and as

Impartiality and Independence of Judges : The Development in European Case Law

Both the European Convention for the Protection of Human Rights and Fundamental Freedoms (ECHR) and the Charter of Fundamental Rights of the European Union (CFR) include the right to a fair trial by an independent and impartial tribunal established by law. The exact meaning of the phrase ‘an independent and impartial tribunal established by law’ has developed in case law. In this article, I analys

Sensory impairment of the upper limb after stroke: influence on daily life and effects of a novel training approach

Abstract: Sensory impairments in the upper limb are common after stroke. Different sensory modalities can be affected such as sense of touch, pressure, pain, temperature and proprioception. The sensory impairments can negatively affect motor function, dexterity and the ability to perform daily activities. Despite these problems limited attention is paid to sensory impairments in stroke rehabilitat

Tricuspid regurgitation management : a systematic review of clinical practice guidelines and recommendations

Tricuspid regurgitation (TR) is a highly prevalent condition and an independent risk factor for adverse outcomes. Multiple clinical guidelines exist for the diagnosis and management of TR, but the recommendations may sometimes vary. We systematically reviewed high-quality guidelines with a specific focus on areas of agreement, disagreement, and gaps in evidence. We searched MEDLINE and EMBASE (1 J
