PURPOSE: Epinephrine is used in local anesthetics to induce vasoconstriction and thus reduce bleeding and prolong the anesthetic effect. Finding the optimal delay between the administration of the anesthetic and skin incision to ensure vasoconstriction and minimize bleeding is important and has recently become the subject of debate. This is the first study to assess blood perfusion and oxygen satu

Histology is a long standing and well-established gold standard for pathological characterizations. In recent years however, synchrotron radiation-based micro-computed tomography (SRμCT) has become a tool for extending the imaging of two-dimensional thin sections into three-dimensional imaging of tissue blocks, enabling so-called virtual histology with arbitrary clipping planes, volumetric renderi

BACKGROUND: Over the past decades, the focus on the regenerative properties of platelets (PLTs) has intensified and many PLT-derived growth factors are readily used in medical settings. A general lack of standardization in the preparation of these growth factors remains, however, and this study therefore examines the dynamics of growth factors throughout the freeze-thaw procedure.STUDY DESIGN AND

BACKGROUND: Platelet lysate is a readily available source of growth factors, and other mediators, which has been used in a variety of clinical applications. However, the product remains poorly standardized and the present investigation evaluates the composition of platelet lysate obtained from either fresh or stored pathogen-inactivated platelet units.MATERIALS AND METHODS: Platelet pooled units (

Estrogen receptor alpha (ERα, encoded by ESR1) is a well-characterized transcription factor expressed in more than 75% of breast tumors and is the key biomarker to direct endocrine therapies. On the other hand, much less is known about estrogen receptor beta (ERβ, encoded by ESR2) and its importance in cancer. Previous studies had some disagreement, however most reports suggested a more favorable

Nature-based solutions (NBS) attract a growing interest in research and practice due to their potential to address climate change while improving human health and well-being and safeguarding biodiversity. The integration of the NBS concept in urban governance, however, is still emerging and it faces regulatory, political, financial and cognitive barriers. While the literature acknowledges an incre

Electric vehicles could help reduce greenhouse gas emissions and deliver a sustainable transport system. But the full life cycle of electric vehicles needs to be considered in order to avoid creating resource issues while trying to achieve the necessary climate goals.

En berättelse om organisering blandar organisationsteorins grunder med berättelsen om modeföretaget Mess. Genom skildringen av människorna och händelserna i och runt företaget ser vi framgångar, konflikter och utmaningar i organisationsteorins ljus. Mötet mellan den fiktiva berättelsen och organisationsteorins grundläggande teman ger en förståelse för vad en organisation är och vad organisering be

X-ray free-electron lasers (XFELs) provide high-brilliance pulses, which offer unique opportunities for coherent X-ray imaging techniques, such as in-line holography. One of the fundamental steps to process in-line holographic data is flat-field correction, which mitigates imaging artifacts and, in turn, enables phase reconstructions. However, conventional flat-field correction approaches cannot c

Commentary and analysis of the proposal of the Swedish Ministry of Justice (Ds 2021:30) concerning implementation of Article 17 Directive 2019/790 on copyright and related rights in the Digital Single Market (DSM Directive). Part 2 of 2.

Accurate and up-to-date land cover maps inform and support effective management and policy decisions. Describing phenological changes in spectral response using time-series data may help to distinguish vegetation types, thereby allowing for more specificity within vegetation classification. In this research, we test this by classifying indigenous forest vegetation in New Zealand, using PlanetScope

As both public and private organizations are spending resources on fostering entrepreneurship, we have witnessed the emergence of an entrepreneurship industry. Using the entrepreneurship industry in Sweden as a case and example, this chapter provides an explorative analysis the emergence, manifestations and consequences of cultural ideals within this industry. The analysis reveals how the entrepre

Tennis is an all-year racket sport requiring qualities such as speed, agility, flexibility, and endurance, as competitions may last up to five hours.Elite players have an estimated daily need of carbohydrate (CHO) between 6-10 g/kg to sustain high amounts of training and frequent competitions. Low energy availability (LEA), over time, may impair both health and performance. LEA may cause metabolic

In the shadow of industry, the service sector substantially expanded during the late nineteenth century. This paper analyzes how the creation of industrial employment contributed to this growth of services. I leverage full-count census data from the United States, Great Britain, and Sweden to estimate local employment multipliers. I show that industrial growth was a key driver in the emergence of

Due to its high hole-mobility, GaSb is a highly promising candidate for high-speed p-channels in electronic devices. However, GaSb exhibits a comparably thick native oxide causing detrimental interface defects, which has been proven difficult to remove. Here we present full oxide removal from GaSb surfaces using effective hydrogen plasma cleaning, studied in-situ by synchrotron-based X-ray photoel
