Bees, ants, and wasps are well known to visually navigate when traveling between their nests and foraging sites. When leaving their nest, landmarks in the vicinity are memorized and used upon return to locate the nest entrance.1,2 The Neotropical nocturnal sweat bee Megalopta genalis navigates under the forest canopy at light intensities ten times dimmer than starlight.3 Despite these dim conditio

BACKGROUND: Recent studies have found that particulate matter (PM) attached radioactivity was associated with certain adverse health effects including increased blood pressure and lung dysfunction. However, there has been no investigation on the direct effect of PM radioactivity on mortality.METHODS: Exposures to ambient PM gamma activities were determined using U.S. EPA RadNet data. Data on daily

While the effects of particulate matter (PM) on morbidity and mortality are well-established, the specific properties of PM responsible for these effects are still not completely understood. However, identifying the toxic properties of particles is critical for developing cost-effective air quality standards and ultimately protecting public health. This dissertation investigates the potential heal

Academia, as many other sectors, has faced wide-ranging disruptions due to COVID-19, with teaching and research activity conducted entirely online in many countries. Before the pandemic grounded travel, academics were often hypermobile, some traveling more than 150,000 kilometers per year for conferences, board meetings, collaborations, fieldwork,seminars, and lectures. It is no surprise then that

In this paper we look at the implications of a prospective emerging technology for the case in favor of, or against, postmenopausal motherhood. Technologies such as in vitro derived gametes (sperm and eggs derived from non-reproductive cells) have the potential to influence the ways in which reproductive medicine is practiced, and will bring new dimensions to debates in this area. We explain what

Background: Accumulation of alpha-synuclein (α-syn) is a main pathological hallmark of Parkinson’s and related diseases, which are collectively known as synucleinopathies. Growing evidence has supported that the same protein can induce remarkably distinct pathological progresses and disease phenotypes, suggesting the existence of strain difference among α-syn fibrils. Previous studies have shown t

The costly and complex needs for children with long-term illness are challenging. Safe eHealth communication is warranted to facilitate health improvement and care services. This mixed-methods study aimed to describe parents’ usage and experiences of communicating with professionals during hospital-to-home-transition after their child’s preterm birth or surgery for col-orectal malformations, using

In Asia, the comprehensiveness of political finance systems and the level of implementation vary significantly across countries. This policy paper draws on the 2018 data of the International IDEA Political Finance Database and covers South Asia, South East Asia and East Asia. It investigates three key questions: What are the main corruption risks associated with the funding of political parties an

Non-alcoholic steatohepatitis (NASH), one of the deleterious stages of non-alcoholic fatty liver disease, remains a significant cause of liver-related morbidity and mortality worldwide. In the current work, we used an exploratory data analysis to investigate time-dependent cellular and mitochondrial effects of different supra-physiological fatty acids (FA) overload strategies, in the presence or a

Purpose: The application of automated image analyses could improve and facilitate standardization and consistency of quantification in [18F]DCFPyL (PSMA) PET/CT scans. In the current study, we analytically validated aPROMISE, a software as a medical device that segments organs in low-dose CT images with deep learning, and subsequently detects and quantifies potential pathological lesions in PSMA P

We have identified a first group of 33 new candidates for symbiotic stars (SySt) of the accreting-only variety among the 600 255 stars so far observed by the GALactic Archaeology with HERMES (GALAH) high-resolution spectroscopic survey of the Southern hemisphere, more than doubling the number of those previously known. GALAH aims to high latitudes and this offers the possibility to sound the Galax

OBJECTIVES: To compare treatment retention and response to secukinumab vs adalimumab, including the other four TNF inhibitors (TNFi) as comparators, in PsA. METHODS: All patients with PsA starting secukinumab or a TNFi in 2015-2018 were identified in the biologic registers of the Nordic countries. Data on comorbidities were linked from national registers. One-year treatment retention and hazard ra

Mot bakgrund av ett förändringstryck på offentlig sektor lanseras i dag flera innovationer för organisatorisk förändring. I det här kapitlet analyseras hur aktörerna som är involverade i dessa processer konstruerar, reproducerar och saluför förändringsidéer genom berättelser om offentlig sektors förnyelse –men också hur berättelserna knyter aktörerna samman och skapar nya roller och koalitioner.

Objectives: We aimed to conduct a systematic review and meta-analysis on the incidence and prevalence of SSc covering the entire literature. Methods: This study followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement of 2009. We conducted a systematic search in MEDLINE, Web of Science and Embase to identify articles reporting incide
