The clinical presentation of colonic juvenile polyps with abdominal discomfort and occult rectal bleedings make them difficult to recognize. The aim was to report the clinical features of colonic juvenile polyps in children referred to colonoscopy and evaluate fecal calprotectin (FCP) as a screening biomarker for their diagnosis.
Dermatan sulfate is a highly sulfated polysaccharide and has a variety of biological functions in development and disease. Iduronic acid domains in dermatan sulfate, which are formed by the action of two DS-epimerases, have a key role in mediating these functions. We have identified the catalytic site and three putative catalytic residues in DS-epimerase 1, His205, Tyr261 and His450, by tertiary s
Intestinal-derived chemokines have a central role in orchestrating immune cell influx into the normal and inflamed intestine. Here, we identify the chemokine CCL6 as one of the most abundant chemokines constitutively expressed by both murine small intestinal and colonic epithelial cells. CCL6 protein localized to crypt epithelial cells, was detected in the gut lumen and reached high concentrations
BACKGROUND AND AIMS: More knowledge is needed about patterns of healthcare consumption at different times during old age, particularly with regard to the relationship between various agents in the healthcare and social services system. One aim was to investigate healthcare costs in the public medical healthcare system in men and women (65+) and, with regard to age, in the two years prior to the st
A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test
The construction of an urea sensitive device based on a conducting polymer is described. The conducting polymer (polypyrrole) was exposed only to a gas-phase; this led to a significant improvement in its stability. A DC-resistometric measuring principle was used, which required only simple measuring equipment. The device responded rapidly to between 0 and 500 mM urea, with resistance changes of be
Background People applying for a housing adaptation (HA) grant are at great risk of participation restrictions due to declining capacity and environmental barriers. Aim To investigate the association of person-, environment-, and activity-related factors with participation frequency and satisfaction among people applying for a housing adaptation grant. Material and methods Baseline cross-sectional
Appropriate evaluation and experimental design are fundamental for empirical sciences, particularly in data-driven fields. Due to the successes in computational modeling of languages, for instance, research outcomes are having an increasingly immediate impact on end users. As the gap in adoption by end users decreases, the need increases to ensure that tools and models developed by the research co
Migratory birds must make complex decisions to use wind to their advantage during flight and increasing flight performance is particularly important while crossing ecological barriers. Age-related differences in how birds deal with wind have suggested experience improves necessary skills in gaining positive wind support. However, differences in wind support between age groups over ecological barri
Purpose: To explore stakeholders’ perceptions of the coordination of health and rehabilitation services for persons with disabilities in Sierra Leone. Materials and methods: A qualitative study including seven focus group discussions with health, rehabilitation, and disability organisations stakeholders in Sierra Leone. Content analysis was used for data analysis. Results: One theme emerged; poor
In the coming renewables-based energy transition, global electricity consumption is expected to double by 2050, entailing widespread end-use electrification, with significant impacts on energy efficiency. We develop a long-run, worldwide societal exergy analysis focused on electricity. Our 1900–2017 electricity world database contains the energy carriers used in electricity production, final end-u
Although the UN concluded, already in 1997, that water would be the most contentious issue of the 21st century, water governance is still confused, nearly everywhere. Even the severe impacts of escalating water bankruptcy and global warming have so far failed to incur a marked improvement in governance systems. The global community has adopted sustainable development as a common vision and guide f
Perovskite light-emitting diodes (PeLEDs) have recently shown significant progress with external quantum efficiencies (EQEs) exceeding 20%. However, PeLEDs with pure-red (620−660 nm) light emission, an essential part for full-color displays, remain a great challenge. Herein, a general approach of spacer cation alloying is employed in Ruddlesden–Popper perovskites (RPPs) for efficient red PeLEDs wi
With the advent of nationwide mammography screening programmes, a number of natural history models of breast cancers have been developed and used to assess the effects of screening. The first half of this article provides an overview of a class of these models and describes how they can be used to study latent processes of tumour progression from observational data. The second half of the article
Lunds kommun äger LKF, Lunds Kommuns Fastighets AB. LKF i sin tur äger och förvaltar ett stort fastighetskapital. Marknadsvärdet uppskattas till omkring 16 000 miljoner kronor för närvarande. En central fråga infinner sig: förvaltas detta kapital på ett effektivt sätt? Ger den nuvarande förvaltningen en gynnsam avkastning åt medborgarna i Lunds kommun? För att finna ett svar på denna fråga har Lun
Objectives: To investigate factors associated with multiple induced abortions. Materials and methods: A multi-centre cross-sectional survey among abortion-seeking women (n = 623;14-47y) in Sweden, 2021. ‘Multiple abortions’ was defined as having had ≥2 induced abortions. This group was compared to women with a previous experience of 0-1 induced abortion. Regression analysis was conducted to determ
