Low Frequency of Intratumor Heterogeneity in Bladder Cancer Tissue Microarrays

Background: Intratumoral heterogeneity (ITH) is associated with clinical challenges such as possible differences in response to treatment and difficulties in classifying the tumor. Previously, ITH has been described in bladder cancer using detailed genetic analyses. However, in this disease, it is not known to what extent ITH actually occurs, or if it involves molecular subtyping, when assessment

Intraoperative versus postoperative rendezvous endoscopic retrograde cholangiopancreatography to treat common bile duct stones during cholecystectomy

Background and Aim: The rendezvous postoperative endoscopic retrograde cholangiopancreatography (ERCP) technique has been introduced as a modification of the single-session rendezvous intraoperative ERCP procedure in the management of concurrent common bile duct stones during cholecystectomy. There are no reports on the impact of this modified technique on post-ERCP morbidity. The objective of the

Club cell secretory protein (CC16) in gastric fluid at birth and subsequent lung disease in preterm infants

Background: Club cell secretory protein (CC16) probably has a role in protecting the lung from inflammation. Aim: To evaluate if low levels of CC16 in gastric fluid at birth, reflecting low levels of CC16 in the lung, would be associated with lung inflammation and respiratory morbidity. Methods: A study of 64 infants with mean gestational age 26.1 weeks. CC16 was analyzed in gastric fluid at birth

Annual flower strips support pollinators and potentially enhance red clover seed yield

Ecological intensification provides opportunity to increase agricultural productivity while minimizing negative environmental impacts, by supporting ecosystem services such as crop pollination and biological pest control. For this we need to develop targeted management solutions that provide critical resources to service-providing organisms at the right time and place. We tested whether annual str

Regional times to equilibria and their impact on semi-quantification of [18F]AV-1451 uptake

The semi-quantitative estimate standardised uptake value ratios (SUVR) correlate well with specific binding of the tracer expressed as distribution volume ratios (DVR) for the tau positron emission tomography tracer [18F]AV-1451 uptake and are therefore widely used as proxy for tracer binding. With regard to tracer kinetic modelling, there exists a time point when SUVR deviates minimally from DVR,

The financial burden of a fee free primary education on rural livelihoods–a case study from rural Iringa Region, Tanzania

This article explores the financial dilemma from a household level perspective of paying for primary education in Tanzania. In 2001, the primary education fee was abolished in a serious attempt to achieve free universal primary education. By eliminating what was perceived as the main obstacle for reaching education for all, the enrollment rates were expected to increase. However, the schools thems

När karriären krackelerar? : En studie om hur unga journalister tänker kring situationen på arbetsmarknaden

Den här uppsatsen låter sex unga journalister komma till tals med avseende på hur de tänker kring förhållandena på arbetsmarknaden. Syftet är att med hjälp av en kvalitativ intervjustudie belysa hur unga journalister tänker kring sin karriär, framtid och livet vid sidan av yrket.Arbetsgivarna inom mediebranschen tillhör dem som i störst utsträckning kringgår lagen om anställningsskydd (LAS). Det i

From conflict to compromise: The importance of mediation in Swedish work stoppages 1907-1927

Institutions for prevention and resolution of industrial conflicts were introduced all over the world in the early twentieth century. We use a new dataset of geocoded strikes and lockouts to analyze the impact of mediation on conflict outcomes in Sweden for the period 1907–1927. Causality is identified by using the distance from the mediator’s place of residence to the conflict as an instrument. D

Patient-reported and performance-based measures of walking in mild–moderate Parkinson's disease

Background: Knowledge of the relationships between patient-reported and performance-based walking measures in Parkinson's disease (PD) should inform clinical decision-making. The Walk-12G reliably captures perceived walking difficulties but has not been compared to performance-based walking in laboratory or free-living settings or across different groups. Objectives: To investigate the relationshi

WNT5A as a therapeutic target in breast cancer

Despite the clinical development of novel adjuvant and neoadjuvant chemotherapeutic drugs, metastatic breast cancer is one of the leading causes of cancer-related death among women. The present review focuses on the relevance, mechanisms, and therapeutic potential of targeting WNT5A as a future anti-metastatic treatment strategy for breast cancer patients by restoring WNT5A signaling as an innovat

A System Dynamics Assessment of the Supply of Molybdenum and Rhenium Used for Super-alloys and Specialty Steels, Using the WORLD6 Model

The extraction, supply, market price and recycling of the metals molybdenum and rhenium were modelled using an integrated system dynamics model. The resource estimates made here resulted in significantly larger estimates than earlier studies for molybdenum. Present molybdenum resources are about 75–80 million ton and about 7 million ton has been mined to date. The ultimately recoverable resources

Identification of genetic biomarkers for the risk prediction of recurrent venous thromboembolism. Risk prediction of recurrent VTE.

Background: Venous thromboembolism (VTE) is the third most frequent life-threatening cardiovascular disease with an annual incidence rate of 1-2 per 1000 person-years. After the diagnosis for primary VTE, about 20-30% patients develop a recurrence within 5-years. VTE recurrence can be prevented by anticoagulants, albeit at the risk of severe bleeding. Heritability of VTE is high and hereditary fac

Molecular diffusion in microemulsions

The interest in studies of diffusional processes in microemulsions has grown rapidly during the past few years. The reasons are an increased number of available techniques providing easily interpretable data and the realization that self-diffusion data give unique information on the molecular organization and structure of microemulsions. Furthermore, many current and potential applications of micr

Development and characterization of sensitive, energy-independent solid-state photon dosemeters with high spatial and temporal resolution. Applications in clinical radiology and radiation protection.

AbstractModern medicine and health care rely on a variety of diagnostic and therapeutic equipment and methods that involve ionizing radiation. To guarantee quality and the safety of patients and staff, advanced radiation detectors and dosemeters are needed that have low energy and operate with directional independence for X-ray and γ-ray photons. Similar instruments are also of great importance fo

People and parking requirements : Residential attitudes and day-to-day consequences of a land use policy shift towards sustainable mobility

A land use policy shift is taking place in a growing number of cities regarding parking, whereby a conventional supplymanagement approach is being replaced with a parking management approach. As part of this policy shift, manycities are lowering their parking requirements. This study analysed changes in car use, car ownership, spatial parkingpatterns and the consequences for the everyday life of r

The Swedish joint action method against drink driving—a study of suspected drink drivers’ own experiences

Objective: In Sweden, a joint action method called SMADIT is in use, where the police quickly offer help from the social services or the dependency care and treatment service to suspected drink drivers. The objective of this article is to analyze the experiences of suspected drink drivers who accepted the offer of help and what it meant for them. The knowledge can be used to improve procedures and
