Decoding mechanical cues by molecular mechanotransduction
Cells are exposed to a variety of mechanical cues, including forces from their local environment and physical properties of the tissue. These mechanical cues regulate a vast number of cellular processes, relying on a repertoire of mechanosensors that transduce forces into biochemical pathways through mechanotransduction. Forces can act on different parts of the cell, carry information regarding ma
Virtual Clinical Trials in Medical Imaging System Evaluation and Optimisation
Virtual clinical trials (VCTs) can be used to evaluate and optimise medical imaging systems. VCTs are based on computer simulations of human anatomy, imaging modalities and image interpretation. OpenVCT is an open-source framework for conducting VCTs of medical imaging, with a particular focus on breast imaging. The aim of this paper was to evaluate the OpenVCT framework in two tasks involving dig
Clinical Characteristics and Self-Harm in Forensic Psychiatric Patients
Self-harm, comprising non-suicidal self-injury, and suicide attempts, is a serious and potentially life-threatening behavior that has been associated with poor life quality and an increased risk of suicide. In forensic populations, increased rates of self-harm have been reported, and suicide is one of the leading causes of death. Aside from associations between self-harm and mental disorders, know
Emotion Regulation and Self-Harm Among Forensic Psychiatric Patients
Emotion regulation has been specifically linked to both non-suicidal self-injury (NSSI) and attempted suicide. It is also known that self-harm is disproportionally higher (30–68.4%) in forensic samples than in the general population, yet knowledge about the association between emotion regulation and self-harm in forensic settings is scarce. The purpose of this study was to describe emotion regulat
Luftföroreningshalter på förskolegårdar
På uppdrag av Naturvårdsverket har avdelningen för Arbets- och miljömedicin vid Lunds Universitet utfört studie kring luftföroreningssituationen på förskolegårdar.Denna studie består av tre delar vara av en är en kunskapsinventering bland landets kommuner kring luftkvalitén på förskolebarns utemiljöer och effekter/strategier för att eventuellt förbättra detta. (sedan tidigare publicerad i denna ra
Levetiracetam and N-Cadherin Antibody Alleviate Brain Pathology Without Reducing Early Epilepsy Development After Focal Non-convulsive Status Epilepticus in Rats
Focal non-convulsive status epilepticus (fNCSE) is a neurological condition characterized by a prolonged seizure that may lead to the development of epilepsy. Emerging experimental evidence implicates neuronal death, microglial activation and alterations in the excitatory and inhibitory synaptic balance as key features in the pathophysiology following fNCSE. We have previously reported alterations
How does image quality affect radiologists’ perceived ability for image interpretation and lesion detection in digital mammography?
Objectives: To study how radiologists’ perceived ability to interpret digital mammography (DM) images is affected by decreases in image quality. Methods: One view from 45 DM cases (including 30 cancers) was degraded to six levels each of two acquisition-related issues (lower spatial resolution and increased quantum noise) and three post-processing-related issues (lower and higher contrast and incr
Extreme altitudes during diurnal flights in a nocturnal songbird migrant
Billions of nocturnally migrating songbirds fly across oceans and deserts on their annual journeys. Using multisensor data loggers, we show that great reed warblers (Acrocephalus arundinaceus) regularly prolong their otherwise strictly nocturnal flights into daytime when crossing the Mediterranean Sea and the Sahara Desert. Unexpectedly, when prolonging their flights, they climbed steeply at dawn,
Correction of pathology in mice displaying Gaucher disease type 1 by a clinically-applicable lentiviral vector
This study evaluates a clinically applicable lentiviral vector for treatment of Gaucher disease type 1. Hematopoietic stem cells transduced with the vector and transplanted into a mouse model successfully halted or reversed pathology. These data were used as proof-of-concept for regulatory filing enabling the commencement of an international phase 1/2 clinical trial.
Assessment of a tumour growth model for virtual clinical trials of breast cancer screening
Image-based analysis of breast tumour growth rate may help optimize breast cancer screening and diagnosis. It may improve the identification of aggressive tumours and suggest optimal screening intervals. Virtual clinical trial (VCT) is a simulation-based method used to evaluate and optimize medical imaging systems and design clinical trials. Our work is motivated by desire to simulate multiple scr
Statin therapy is associated with epigenetic modifications in individuals with Type 2 diabetes
Aim: Statins lower cholesterol and reduce the risk of cardiovascular disease. However, the exact mechanisms of statins remain unknown. We investigated whether statin therapy associates with epigenetics in Type 2 diabetes (T2D) patients. Materials & methods: DNA methylation was analyzed in blood from newly diagnosed T2D patients in All New Diabetics in Scania (ANDIS) and a replication cohort Al
Aortic Stiffness, Inflammation, and Incidence of Cardiovascular Events in Elderly Participants From the General Population
Low-grade inflammation and arterial stiffness are key factors in the development of vascular aging. However, the interplay between arterial stiffness and inflammation for cardiovascular (CV) disease is unclear. Aortic pulse wave velocity (aPWV) and the inflammatory markers, high-sensitivity C-reactive protein (CRP) and orosomucoid, were measured in 2710 participants (median age: 72 years). These p
Factors associated with longitudinal change of meniscal extrusion in overweight women without clinical signs of osteoarthritis
OBJECTIVES: To identify variables associated with longitudinal change in meniscal extrusion, which might be used as possible targets for knee osteoarthritis (KOA) prevention. METHODS: In a high-risk population of middle-aged overweight women, meniscal extrusion was assessed with magnetic resonance imaging (1.5 T, coronal proton density, in-plane resolution 0.5 mm2, Sante DICOM Editor) at baseline
Lymph swelling after radical prostatectomy and pelvic lymph node dissection
Seasonally divided moult in the Barred Warbler (Sylvia nisoria) is an endogenously controlled strategy
The seasonal timing of moult in migratory birds is an adaptation to cope with time constraints in the annual cycle. Kiat and Izhaki analysed moult patterns in Palaearctic passerines and rejected the proposition that seasonally divided moult is an endogenously controlled strategy. Instead, they advocated the view that it occurs due to a flexible and opportunistic timing of moult. In contrast, we ar

BMP signaling is required for postnatal murine hematopoietic stem cell self-renewal
Life-long production of blood from hematopoietic stem cells (HSC) is a process of strict modulation. Intrinsic and extrinsic signals govern fate options like self-renewal – a cardinal feature of HSC. Bone morphogenetic proteins (BMP) have an established role in embryonic hematopoiesis, but less is known about its functions in adulthood. Previously, SMAD-mediated BMP signaling has been proven dispe
Establishing metastatic prostate cancer quality indicators using a modified Delphi approach
Background: There is variation in the care provided to men with metastatic prostate cancer (mPCa). There has been no previous set of quality indicators (QIs) regarding the management of men with mPCa. The objective of this study is to develop a set of international mPCa-specific QIs, which will enable global benchmarking of quality of care. Materials and methods: Potential QIs were identified thro
