Phylogeographic Assessment Reveals Geographic Sources of HIV-1 Dissemination Among Men Who Have Sex With Men in Kenya

HIV-1 transmission dynamics involving men who have sex with men (MSM) in Africa are not well understood. We investigated the rates of HIV-1 transmission between MSM across three regions in Kenya: Coast, Nairobi, and Nyanza. We analyzed 372 HIV-1 partial pol sequences sampled during 2006–2019 from MSM in Coast (N = 178, 47.9%), Nairobi (N = 137, 36.8%), and Nyanza (N = 57, 15.3%) provinces in Kenya

Fractionation of sugar beet pulp polysaccharides into component sugars and pre-feasibility analysis for further valorisation

Sugar beet pulp (SBP) is a by-product formed in large amounts during the production of refined sugar and is currently used as a low-cost feed for livestock. The dry SBP comprises largely three polysaccharides (75–85%), cellulose, hemicellulose and pectin, whose component sugars constitute potential valuable feedstock for producing building blocks for chemicals and materials. In the present study,

Multivariate mining of an alpaca immune repertoire identifies potent cross-neutralizing SARS-CoV-2 nanobodies

Conventional approaches to isolate and characterize nanobodies are laborious. We combine phage display, multivariate enrichment, next-generation sequencing, and a streamlined screening strategy to identify numerous anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nanobodies. We characterize their potency and specificity using neutralization assays and hydrogen/deuterium exchange m

A Machine-Learning-Based Bibliometric Analysis of the Scientific Literature on Anal Cancer

Squamous-cell carcinoma of the anus (ASCC) is a rare disease. Barriers have been encountered to conduct clinical and translational research in this setting. Despite this, ASCC has been a prime example of collaboration amongst researchers. We performed a bibliometric analysis of ASCC-related literature of the last 20 years, exploring common patterns in research, tracking collaboration and identifyi

Conversion Narratives of Unaccompanied Refugee Minors in the Church of Sweden

From 2014 to 2016, 44,617 unaccompanied refugee minors (URM) arrived and sought asylum in Sweden. Since their arrival, the Church of Sweden (CoS) has received hundreds of these young people seeking to join the church and be baptised as Christians. This phenomenon is notable in an institution that is otherwise declining in membership and which is not known for actively recruiting new members. While

High CD34 surface expression in BCP-ALL predicts poor induction therapy response and is associated with altered expression of genes related to cell migration and adhesion

Minimal residual disease (MRD) constitutes the most important prognostic factor in B-cell precursor acute lymphoblastic leukemia (BCP-ALL). Flow cytometry is widely used in MRD assessment, yet little is known regarding the effect of different immunophenotypic subsets on outcome. In this study of 200 BCP-ALL patients, we found that a CD34-positive, CD38 dim-positive, nTdT dim-positive immunophenoty

A Phase II Trial of a Personalized, Dose-Intense Administration Schedule of 177Lutetium-DOTATATE in Children With Primary Refractory or Relapsed High-Risk Neuroblastoma–LuDO-N

Background: Half the children with high-risk neuroblastoma die with widespread metastases. Molecular radiotherapy is an attractive systemic treatment for this relatively radiosensitive tumor. 131I-mIBG is the most widely used form in current use, but is not universally effective. Clinical trials of 177Lutetium DOTATATE have so far had disappointing results, possibly because the administered activi

Growth of non-English-language literature on biodiversity conservation

English is widely recognized as the language of science, and English-language publications (ELPs) are rapidly increasing. It is often assumed that the number of non-ELPs is decreasing. This assumption contributes to the underuse of non-ELPs in conservation science, practice, and policy, especially at the international level. However, the number of conservation articles published in different langu

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

European Association of Urology Guidelines on Renal Cell Carcinoma : The 2022 Update

Context: The European Association of Urology (EAU) Renal Cell Carcinoma (RCC) Guideline Panel has prepared evidence-based guidelines and recommendations for the management of RCC. Objective: To present a summary of the 2022 RCC guideline, which is based on a standardised methodology including systematic reviews (SRs) and provides transparent and reliable evidence for the management of RCC. Evidenc

Definition and sonographic reporting system for Cesarean scar pregnancy in early gestation : modified Delphi method

Objective: To develop a standardized sonographic evaluation and reporting system for Cesarean scar pregnancy (CSP) in the first trimester, for use by both general gynecology and expert clinics. Methods: A modified Delphi procedure was carried out, in which 28 international experts in obstetric and gynecological ultrasonography were invited to participate. Extensive experience in the use of ultraso

Bioderived, chiral and stable 1-dimensional light-responsive nanostructures : Interconversion between tubules and twisted ribbons

HYPOTHESIS: Self-assembling molecular structures responding to light stimulus are appealing for applications as sensing and drug delivery. Supramolecular nanotubes have a relevant potential in nanotechnology as they can be used to encapsulate different loads like drugs, biological macromolecules, and nanomaterials. In addition, they are suitable elements for novel supracolloidal materials. Structu

Adaptation to microenvironmental stress in glioblastoma. Mechanistic studies and potential targets.

Although the overall mortality in cancer is steadily decreasing, major groups of patients still respond poorly to available treatments. The key clinical challenge addressed in the present thesis work relates to the inherent adaptive capacity of glioblastoma (GBM) tumors, resulting in treatment resistance and dismal prognosis. GBM represents the most common and lethal primary CNS tumor in adults. T

Stability of Robotic Obstacle Avoidance and Force Interaction

Stability problems associated with robot control with obstacle avoidance are analysed. Obstacle avoidance algorithms based on potential function are revised to accomplish stable re-design. A stability proof using Lyapunov theory and passivity theory is provided for the re-designed obstacle avoidance algorithm. The paper presents a modification of potential functions for obstacle avoidance aiming t

Probabilistic analysis of climate change impact on chloride-induced deterioration of reinforced concrete considering Nordic climate

The impact of climate change on the deterioration of reinforced concrete elements have been frequently highlighted as worthy of investigation. This article addresses this important issue by presenting a time-variant reliability analysis to assess the effect of climate change on four limit states; the probabilities of corrosion initiation, crack initiation, severe cracking, and failure of a simply

Years of plenty, years of want? : An introduction to finance and the family life cycle

Research suggests that until recently families in history could only avoid episodes of poverty if they put money aside. By helping to smooth consumption over the family life cycle, finance could prevent impoverishment, and is also likely to have had an effect on family life. Saving may have influenced cohabitation structures and the timing and incidence of birth, marriage, and death. That families

Strategies of visibility in the smart city

Cities across the world are increasingly labelling themselves as smart in one way or another. At the same time, this smartness appears amorphous or invisible in its built urban environment. Critical researchers writing on the smart city regularly express confusion or exasperation about precisely the difficulty to locate the smart in the city. Visibility of the smart city is not a given. This artic

Hur hänger Aktie-SM 1979 ihop med nyliberalismens framväxt i Sverige? Vilken roll spelade kokainet för Sigmund Freuds syn på normalitet? Hur har månen påverkat människan genom historien? Vad fick Mary Wollstonecraft att på resa genom ett kargt Norden omvärdera sin syn på revolutioner? Och vad kan en hästslaktare i 1800-talets Stockholm säga oss om människans paradoxala förhållande till djuren?Bild

Hippocampal Function Is Impaired by a Short-Term High-Fat Diet in Mice: Increased Blood–Brain Barrier Permeability and Neuroinflammation as Triggering Events

Worldwide, and especially in Western civilizations, most of the staple diets contain high amounts of fat and refined carbohydrates, leading to an increasing number of obese individuals. In addition to inducing metabolic disorders, energy dense food intake has been suggested to impair brain functions such as cognition and mood control. Here we demonstrate an impaired memory function already 3 days
