Background: Slower adaptation of the QT interval to sudden changes in heart rate has been identified as a risk marker of ventricular arrhythmia. The gradual changes observed in exercise stress testing facilitates the estimation of the QT-RR adaptation time lag. Methods: The time lag estimation is based on the delay between the

As one of the most critical components of the vanadium redox flow battery (VRFB), the ion exchange membrane directly influences the battery efficiency and cycle life. Herein, poly(isatin triphenyl) (PIT) containing a lactam structure and devoid of ether bonds is synthesized from isatin and p-terphenyl under superacid catalysis. To achieve the ion transport and investigate the impact of side chain

During the Swedish-Russian Tundra Ecology -94 expedition one of the goals was to describe the local population fluctuations of Siberian lemmings over the Eurasian tundra. In order to compensate for the lack of repeated sampling, we used 4 different estimates to determine the phase position of the lemming populations at the different sites: i) the number of lemmings trapped per unit time; ii) the a

In wildland fires, burning particles of vegetative material can be lofted by the fire plume and are subsequently transported horizontally by cross wind. Depending on the state of the firebrands (flaming, smoldering, inert hot, inert cold) upon landing they bear the potential to cause secondary fires. The present work introduces the reader to existing theoretical analyses of the problem of combusti

Background Ozone is a pollutant known to cause adverse effects on human health. It is formed by reactions between nitrogen oxides (NOx) and hydrocarbons under the influence of sunlight. In urban areas ozone is consumed oxidating nitrogen oxide (NO) to nitrogen dioxide (NO2). Despite the potential to cause adverse health effects, the local spatial distribution of ozone and the relationship between

Background: Commuting, transportation from the home to the work place has been claimed to increase the material wealth. Although economy and flexibility to choose where to live and work will improve for the individual, several studies have shown that health become aggravated with increased commuting. One plausible explanation to the negative health is reduced social capital. Aim: Our primary hypot

OBJECTIVE: To investigate if treatment with transurethral enucleation of the prostate (TUEP) during the learning curve is as efficient and safe in the short term as transvesical open prostate enucleation (OPE), in patients with benign prostatic obstruction (BPO) > 80 ml in a population in Sweden. Methods: 54 patients with ultrasound verified BPO > 80 ml and indication for surgery underwent TUEP or

The implementation of sputter-deposited TiOx as an electron transport layer in nonfullerene acceptor-based organic photovoltaics has been shown to significantly increase the long-term stability of devices compared to conventional solution-processed ZnO due to a decreased photocatalytic activity of the sputtered TiOx. In this work, we utilize synchrotron-based photoemission and absorption spectrosc

Background: Early detection of treatment response is important for the management of patients with malignant brain tumors such as glioblastoma to assure good quality of life in relation to therapeutic efficacy. Aim: To investigate whether parametric response mapping (PRM) with diffusion MRI may provide prognostic information at an early stage of standard therapy for glioblastoma. Materials and met

Thermoresponsive microgels are one of the most investigated types of soft colloids, thanks to their ability to undergo a Volume Phase Transition (VPT) close to ambient temperature. However, this fundamental phenomenon still lacks a detailed microscopic understanding, particularly regarding the presence and the role of charges in the deswelling process. This is particularly important for the widely

HER2/ERBB2 evaluation is necessary for treatment decision-making in breast cancer (BC), however current methods have limitations and considerable variability exists. DNA copy number (CN) evaluation by droplet digital PCR (ddPCR) has complementary advantages for HER2/ERBB2 diagnostics. In this study, we developed a single-reaction multiplex ddPCR assay for determination of ERBB2 CN in reference to

IntroductionInvasive infections caused by Salmonella are a significant global health concern. This population-based study aimed to comprehensively analyze invasive Salmonella infections in South Sweden, focusing on incidence, clinical presentation, risk factors, and outcomes.MethodsThis population-based observational cohort study, conducted from 2012 to 2022, included all patients with Salmonella

Based on the physical and geographical conditions, the Baltic Region is categorised as a humid climate zone. This means that, there is usually more precipitation than evaporation throughout the year, suggesting that droughts should not occur frequently in this region. Despite the humid climate in the region, the study focused on assessing the spatio-temporal patterns of droughts. The drought event

C-reactive protein (CRP)/Albumin ratio (CAR) seems to mirror disease severity and prognosis in several acute disorders particularly in elderly patients, which we aimed to study. As method we use a prospective study design; the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS; n = 912, women 50%; mean age 70 years, baseline 2001 and 2004, median follow-up 15.0 years, end of fo

Treatment with pancreatic or pancreatic-like microbial enzymes during the suckling period has positive effects on the gut, resulting in a better fat absorption and improved barrier function in pigs. The present study investigated the effects of pancreaticlike enzyme treatment during the pre- or postweaning period on pig growth and nitrogen utilization. Suckling 7- to 14-d-old pigs were gavage fed

Background Individuals without occupational exposure are exposed to mercury (Hg) from diet and dental amalgam. The kidney is a critical organ, but there is limited information regarding the relationship between Hg in kidney (K-Hg), urine (U-Hg), blood (B-Hg), and plasma (P-Hg). Objectives The aim was to determine the relationship between K-Hg, U-Hg, B-Hg, and P-Hg among environmentally exposed ind

The application of geophysics may assist in solving environmental, geotechnical and exploration problems. One commonly used method in such applications is electrical resistivity tomography (ERT). In order to interpret the results, inversion is needed to create models estimating distribution of resistivity in the ground. Several inversion programs are available for geophysicists to use. It is there
