The Xg blood group system : no longer forgotten

This update of the Xg blood group system (Johnson NC. XG: The forgotten blood group system. Immunohematology 2011;27:68-71) notes the identification of a cis-regulatory element of both XG and CD99 expression, remarkably by two independent groups during 2018, and confirmed by another in 2019. A single nucleotide change at the XG locus (rs311103) abolishes GATA1 binding and suppresses both XG and CD

Complications of surgery for gastro-entero-pancreatic neuroendocrine neoplasias

Purpose: Surgery is recommended for most patients with gastro-entero-pancreatic neuroendocrine neoplasias (GEP-NENs). Rates of complications and perioperative mortality have been reported in few mostly retrospective single-center series, but there has been no detailed analysis on risk factors for perioperative complications and mortality to date. Methods: Data of patients with GEP-NENs operated be

The Social Network : How Friends’ Online Behavior and Belongingness Needs Influence Political Activity

Are people more likely to become more politically active through social media when they observe that their friends are active? Previous research has shown that an individual's likelihood of engaging politically is influenced by observations of how friends act through social media, but relatively little is known about how such social influence through social media interacts with personality feature

Multi-Stakeholder Perspectives on Scaling up UK Fashion Upcycling Businesses

Fashion upcycling, the process of using waste clothing and textiles to create new products, is an alternative to business-as-usual practices which can effectively address concerns on excessive consumption of energy and material resources and use of chemicals in the fashion industry. Scaling up fashion upcycling businesses could enable the transition of the fashion industry towards sustainability.

Demonstration-scale enzymatic saccharification of sulfite-pulped spruce with addition of hydrogen peroxide for LPMO activation

The saccharification of lignocellulosic materials like Norway spruce is challenging due to the recalcitrant nature of the biomass, and it requires optimized and efficient pretreatment and enzymatic hydrolysis processes to make it industrially feasible. In this study, we report successful enzymatic saccharification of sulfite-pulped spruce (Borregaard's BALI™ process) at demonstration scale, achiev

Long-term outcome of pT1a–b, cN0 breast cancer without axillary dissection or staging : a prospective observational study of 1543 women

Background: The implementation of screening programmes in Sweden during the mid-1990s increased the number of small node-negative breast cancers. In this era before staging by sentinel node biopsy, routine axillary dissection for staging of early breast cancer was questioned owing to the increased morbidity and lack of perceived benefit. The long-term risk of axillary recurrence when axillary stag

Exposure to surgery is associated with better long-term outcomes in patients admitted to Swedish intensive care units

Background: Long-term outcomes of patients admitted to intensive care units (ICUs) after surgery are unknown. We investigated the long-term effects of surgical exposure prior to ICU admission. Methods: Registry-based cohort study. The adjusted effect of surgical exposure for mortality was examined using Cox regression. Secondary analysis with conditional logistic regression in a case-control subpo

Kontraspionage och hybridkrigföring : En fallstudie av kuppförsöket i Montenegro 2016

Enligt flera definitioner av det något lösa samtida begreppet ”hybridkrigföring”, i betydelsen primärt mellanstatliga konflikter av den typ som utspelade sig på Krim 2014 och i östra Ukraina sedan 2015, är underrättelsekomponenten en central resurs för den angripande parten. Detta öppnar upp en ny roll för kontraspionaget, som utöver sina traditionella uppgifter nu också måste ha beredskap att bem

Antagonistens roll : Vad Napoleon och KGB kan lära oss om beslutsfattandets konst inom militär ledning och underrättelseanalys

Professionalization is a growing trend in both military and intelligence organizations. However, unlike the traditional professions, both military decision-makers and intelligence analysts frequently find themselves locked in a struggle with an intelligent antagonist. One key aspect of professionalization, the teaching of structured, scientifically based knowledge and best practices, can lead to p

Urolithiasis in second-generation immigrant children younger than 18 years of age in Sweden

Aim: To compare incidence of urolithiasis in second-generation immigrant children aged 0-17 years to children of Swedish-born parents. Methods: A nationwide study of individuals residing in Sweden. Urolithiasis was defined as having at least one registered diagnosis of urolithiasis in the Swedish National Patient Register between January 1, 1998 and December 31, 2015. Cox regression analysis was u

Periodontitis and airflow limitation in older Swedish individuals

Aim: To investigate whether there was an association between periodontitis and airflow limitation in older Swedish individuals. Materials and Methods: Study individuals were randomly selected from the Swedish civil registration database representing the ageing population in Karlskrona, Sweden. Clinical and radiographic examinations were performed, alongside which participants completed questionnai

Fourier Method for Valuation of Options under Parameter and State Uncertainty

Mainstream option valuation theory relies implicitly on the assumption that latent states (such as stochastic volatility) and parameters are perfectly known, an assumption that is dubious in many ways. Computing the value of options under the assumption of perfect knowledge will typically introduce bias. Correcting for the bias is straightforward but can be computationally expensive. Fourier-base

Current challenges and coming opportunities in nanoparticle risk assessment

This chapter discusses the key aspects of engineered nanomaterial (ENM) toxicity. The individual properties of ENMs affecting their toxic potential are described, with a special focus on size, shape, and surface charge and functionalization. We present empirical evidence from a range of in vitro and in vivo studies showing potential adverse effects induced via inhalation, ingestion, or skin contac

Abstract in German:Das Hochleistungs-Innenrundschälschleifen mit galvanisch gebundenen CBN-Schleifwerkzeugen ist ein hocheffizientes Fertigungsverfahren für die Innenbearbeitung von gehärteten Futterbauteilen wie Zahnrädern und Lagerringen. Die konturierten Schleifwerkzeuge, welche mit einer konischen Schrupp- und zylindrischen Schlichtzone versehen sind, kombinieren in einem einzelnen Axialhub ei

A 24-Year Follow-up Study on Recidivism in Male Mentally Disordered Sexual Offenders With and Without Psychotic Disorders

There is a lack of knowledge on mentally disordered sex offenders (MDSOs) targeting adult victims, especially regarding recidivism patterns and the specific subgroup with psychiatric disorders. This paper presents index offense data, clinical data, and recidivism patterns over up to 24 years in a cohort of 146 MDSOs, with and without psychotic disorders, sentenced in Sweden between 1993 and 1997.

Pupils' use of school outdoor play settings across seasons and its relation to sun exposure and physical activity

Background: Long outdoor stay may cause hazardous exposure to ultraviolet radiation (UVR) from the sun even at high latitudes as in Sweden (Spring to Autumn). On the other hand, long outdoor stay is a strong predictor of primary school children´s free mobility involving moderate to vigorous physical activity (MVPA). UV-protective outdoor environments enable long outdoor stay. We investigated the c

May the FORS be with you : a system sequel

This article is an update of the review of the FORS system published in Immunohematology in 2017 (Hult AK, Olsson ML. The FORS awakens: review of a blood group system reborn. Immunohematology 2017;33:64-72). This update incorporates the most recently presented knowledge on this still enigmatic system and its genetic, enzymatic, and immunological aspects. Further insight into the genetic variation

Substrate-size choice in European eel (Anguilla anguilla) elvers is not altered by piscivore chemical cues

The European eel Anguilla anguilla Linnaeus 1758 is critically endangered with recruitment estimated at 5–10% of historical levels. Enhancing survival of recruits is pivotal for conservation, and restoration should consider habitat choice of elvers ascending river systems. We experimentally show that newly ascended elvers choose small pebble habitat over finer and larger substrates, regardless of
