Background The effectiveness of cervical cancer screening programs differs widely in different populations. The reasons for these differences are unclear. Routine and comprehensive audits have been proposed as an ethically required component of screening. We performed a nationwide audit of the effectiveness of the Swedish cervical cancer screening program. Methods We identified all invasive cervic
Background: Achlorhydria caused by e.g. atrophic gastritis allows for bacterial overgrowth, which induces chronic inflammation and damage to the mucosal cells of infected individuals driving gastric malignancies and cancer. Enterococcus faecalis (E. faecalis) can colonize achlohydric stomachs and we therefore wanted to study the impact of E. faecalis infection on inflammatory response, reactive ox
Bdellovibrio and like organisms (BALOs) are obligate predatory bacteria that selectively prey on a broad range of Gram-negative bacteria, including multidrug-resistant human pathogens. Due to their unique lifestyle, they have been long recognized as a potential therapeutic and biocontrol agent. Research on BALOs has rapidly grown over the recent decade, resulting in many publications concerning mo
Increased tissue stiffness is a classic characteristic of solid tumors. One of the major contributing factors is increased density of collagen fibers in the extracellular matrix (ECM). Here, we investigate how cancer cells biomechanically interact with and respond to the stiffness of the ECM. Probing the adaptability of cancer cells to altered ECM stiffness using optical tweezers based micro-rheol
The complement system resembles a double-edged sword since its activation can either benefit or harm the host. Thus, regulation of this system is of utmost importance and performed by several circulating and membrane-bound complement inhibitors. The pool of well-established regulators has recently been enriched with proteins that either share structural homology to known complement inhibitors such
A semi-stochastic, statistical reduction method for chemical kinetic schemes based on the ant colony optimization method, is developed for atmospheric chemistry simulations. The prime application is coupled dynamic and chemistry models for simulation of the dispersion and reactivity of chemical species on street scale, i.e. the modelling of urban air pollution in street canyons. The method is desi
We consider thermal fluid structure interaction to model industrial gas quenching in steel forging, where hot steel Is cooled using cold high pressured gas. This allows to define properties of the finished steel part, as for example yield strength, locally at low cost and without environmental problems. For the numerical simulation, a partitioned approach via a Dirichlet-Neumann coupling and a fix
OBJECTIVE: Emergency department length of stay (EDLOS) is linked to crowding and patient outcomes whereas worse prognosis in low socioeconomic status remains poorly understood. We studied whether income was associated with ED process times among patients with chest pain.METHODS: This was a registry-based cohort study on 124,980 patients arriving at 14 Swedish EDs between 2015 and 2019 with chest p
This study examines the articulation of anti-gender politics in the parliamentary debates centred on two citizens’ initiatives in Finland and Romania. Although different in their endeavours (in Finland, supporting equal marriage rights; in Romania, attempting to legislate pre-emptively against them), these citizens’ initiatives resulted in significant defeats for the wider anti-gender campaigns in
Evidence of the effectiveness of the tests used to diagnose Helicobacter pylori (H. pylori) in primary healthcare is limited. This cross-sectional study aims to assess the accuracy of tests used for to diagnose H. pylori infection in primary care patients and its relationship with gastroduodenal pathologies. Over 12 months, 173 primary care patients with dyspeptic symptoms were referred for upper
Rapporten presenterar resultat från ett forskningsprojekt ”Mäta resfria möten” (MRM), som bedrivs av Internationella miljöinstitutet (IIIEE) vid Lunds universitet i 2011-2014 med finansiering från Energimyndigheten och Trafikverket, och syftar till att utveckla ett ramverk, indikatorer och metoder för utvärdering, uppföljning och redovisning av resfria möten (RM), deras användning och effekter på
The lung may be the organ whose mechanical environment needs to be most finely tuned to achieve optimal function. These needs have to be fulfilled at multiple scales, from proper force transmission between the chest wall and the parenchyma to reduction of surface tension by surfactants inside the alveoli. In addition, a plethora of mechanical loads and forces takes place within the lung, from the
Mojtaba Khamenei’s rise to Iran’s supreme leadership represents the consolidation of dynastic power within the Islamic Republic. Long operating behind the scenes through the Supreme Leader’s office and the Islamic Revolutionary Guards, he has been widely viewed as the most likely successor to his father. His leadership signals continuity with the regime’s totalitarian structure and suggests a furt
We have used approximately 40 fs pulses from a Ti:sapphire laser to investigate the ultrafast energy transfer and relaxation dynamics in the light-harvesting pigment-proteins of photosynthetic purple bacteria. Our results reveal two new features, not earlier observed in light-harvesting pigments: (1) ultrafast relaxation characterized by a time constant of approximately 20 fs, which we interpret a
PURPOSE: This study investigated the value of intense follow-up compared with no follow-up after curative surgery of cancer in the colon or rectum. METHODS: One hundred seven patients were randomized to no follow-up (control group; n=54) or intense follow-up (follow-up group; n=53) after surgery and early postoperative colonoscopy. Patients in the follow-up group were followed at frequent interval
The United Nation’s Sustainable Development Goals state that education is both an end and a means for achieving sustainable development. Currently, education for sustainability focuses on (assessing and addressing) the external world of ecosystems, wider socio-economic structures, technology, and governance dynamics. A major shortcoming of such approaches is the neglect of inner dimensions and cap
Urbanisation and climate change are urging cities to find novel pathways leading to a sustainable future. The urban context may be viewed as a new experimentation space to accelerate the transition to a circular economy. Urban symbiosis and circular economy are emerging concepts attracting more and more attention within the urban context. Moreover, new business models are emerging around sharing a
