Androgen dependent mechanisms of pro-angiogenic networks in placental and tumor development

The placenta and tumors share important characteristics, including a requirement to establish effective angiogenesis. In the case of the placenta, optimal angiogenesis is required to sustain the blood flow required to maintain a successful pregnancy, whereas in tumors establishing new blood supplies is considered a key step in supporting metastases. Therefore the development of novel angiogenesis

An integrated acousto- and dielectrophoresis device for tumor cell separation, concentration, and single-cell trapping

Many microfluidic devices have been developed to separate rare cells, e.g. circulating tumor cells. The collection and analysis of the separated rare cells pose a challenge as it may lead to loss of target cells since extremely small number of cells are usually suspended in a large volume after separation. Here, we present an integrated device that allows acoustophoretic target cell separation and

Acoustophoretic manipulation of sub-micron objects enabled by density gradients

Direct and precise manipulation of sub-micron particles such as bacteria, platelets, organelles, microvesicles, exosomes or virus particles is challenging. We describe for the first time how acoustic streaming in the bulk can be efficiently reduced by introducing a density or compressibility gradient and that this enables focusing of 500-nm-diameter particles in a standard acoustophoresis channel.

Children's respiratory health in the context of housing and other social determinants in Rosengård : a cross-sectional study in an immigrant neighbourhood in Sweden

The social determinants of health form a complex and dynamic web, shaping both populationand individual health and disease. The built environment and especially human dwellingsinfluence health in many ways. Associations between factors such as dampness, mouldgrowth, heating/insulation, and crowding on the one hand and respiratory health andinfectious diseases on the other hand have been studied in

Pluralism in Search of Sustainability: Ethics, Knowledge and Methdology in Sustainability Science

Sustainability Science is an emerging, transdisciplinary academic field that aims to help build a sustainable global society by drawing on and integrating research from the humanities and the social, natural, medical and engineering sciences. Academic knowledge is combined with that from relevant actors from outside academia, such as policy-makers, businesses, social organizations and citizens. Th

Treatment of contaminated greywater using pelletised mine water sludge

Precipitated sludge (ochre) obtained from a mine water treatment plant was considered as an adsorbent substance for pollutants, since ochre is relatively free from problematic levels of toxic elements, which could impair on the quality of water to be treated. Artificially created ochre pellets from mixing Portland cement with raw ochre sludge were utilised to remediate either high (HC) or low (LC)

Self-reported exposure to severe events on the labour ward among Swedish midwives and obstetricians : A cross-sectional retrospective study

Background The process of delivery entails potentially traumatic events in which the mother or child becomes injured or dies. Midwives and obstetricians are sometimes responsible for these events and can be negatively affected by them as well as by the resulting investigation or complaints procedure (clinical negligence). Objective To assess the self-reported exposure rate of severe events among m

Neutron-skin effect in direct-photon and charged-hadron production in Pb+Pb collisions at the LHC

A well-established observation in nuclear physics is that in neutron-rich spherical nuclei the distribution of neutrons extends farther than the distribution of protons. In this work, we scrutinize the influence of this so called neutron-skin effect on the centrality dependence of high-pT direct-photon and charged-hadron production. We find that due to the estimated spatial dependence of the nucle

Real-time in situ analysis of biocorona formation and evolution on silica nanoparticles in defined and complex biological environments

Biomolecules such as proteins immediately adsorb on the surface of nanoparticles upon their exposure to a biological environment. The formed adlayer is commonly referred to as biomolecule corona (biocorona) and defines the biological activity and toxicity of the nanoparticle. Therefore, it is essential to understand in detail the biocorona formation process, and how it is governed by parameters li

Global stroke statistics

Background: Up to date data on incidence, mortality, and case-fatality for stroke are important for setting the agenda for prevention and healthcare. Aims and/or hypothesis: We aim to update the most current incidence and mortality data on stroke available by country, and to expand the scope to case-fatality and explore how registry data might be complementary. Methods: Data were compiled using tw

The SICAM-trial : evaluating the effect of spouses' involvement through case management in older patients' fast-track programmes during and after total hip replacement

Aim: The aim of this study was to evaluate the effect of spouses' involvement in older patients' care trajectories, using case management as intervention in total hip replacement through fast-track programmes. Background: Patients need their spouses to be involved in their fast-track programmes and this involvement is often associated with improvements in patient outcomes. However, the effect of s

The effect of voice quality and competing speakers in a passage comprehension task : performance in relation to cognitive functioning in children with normal hearing

Objective: This study explores the effect of voice quality and competing speaker/-s on children’s performance in a passage comprehension task. Furthermore, it explores the interaction between passage comprehension and cognitive functioning. Methods: Forty-nine children (27 girls and 22 boys) with normal hearing (aged 7–12 years) participated. Passage comprehension was tested in six different liste

MetodSåväl kvantitativ som kvalitativ metod har använts.Studie I var en icke-experimentell kvantitativ studie med statistisk analys, och datainsamling före

MiR-155-5p positively regulates CCL17-induced colon cancer cell migration by targeting RhoA

Colorectal cancer is the second most common cause of cancer-related death, which is due to migration of tumor cells to distant sites of metastasis. Accumulating data indicate that mciroRNAs play an important role in several aspects of colon cancer cell biology. Herein, we examined the role of miR-155-5p in colon cancer cell migration induced by the CCL17-CCR4 axis in HT-29 colon cancer cells. We f

Spillovers from targeting of incentives : Exploring responses to being excluded

A growing set of policies involve transfers conditioned upon socially desired actions, such as attending school or conserving forest. However, given a desire to maximize the impact of limited funds by avoiding transfers that do not change behavior, typically some potential recipients are excluded on the basis of their characteristics, their actions or at random. This paper uses a laboratory experi

On the Evolution of the Determinants of Household Poverty in Mexico : a Logistic Regression Analysis

Mexico, the second largest economy in Latin America, has almost eradicated extreme poverty according to the Millennium Development Goals; however, official statistics show that by national standards poverty levels are still quite high, reaching up to half its population. This paper looks into how the determinants of poverty in Mexico have evolved after the last major economic crisis the country ex
