Optical mapping by direct visualization of individual DNA molecules, stretched in nanochannels with sequence-specific fluorescent labeling, represents a promising tool for disease diagnostics and genomics. An important challenge for this technique is thermal motion of the DNA as it undergoes imaging; this blurs fluorescent patterns along the DNA and results in information loss. Correcting for this
IMPORTANCE: The outcomes of newborn infants of women testing positive for SARS-CoV-2 in pregnancy is unclear.OBJECTIVE: To evaluate neonatal outcomes in relation to maternal SARS-CoV-2 test positivity in pregnancy.DESIGN, SETTING, AND PARTICIPANTS: Nationwide, prospective cohort study based on linkage of the Swedish Pregnancy Register, the Neonatal Quality Register, and the Register for Communicab
Att behandla tumörsjukdomar genom injektion av radioaktiva läkemedel är en behandlingsteknik kallad radionuklidterapi. Det radioaktiva läkemedlet består av en radioaktiv isotop, fäst på en målsökande bärarmolekyl, specifik för den vävnad vari man önskar att läkemedlet skall ansamlas. Då den radioaktiva isotopen sönderfaller sänds joniserande strålning ut; strålning med förmågan att jonisera molekyIntroduction: There is a need of reassessment of radiation absorbed dose specification in nuclear medicine, taking the non-uniformities in the distribution of radioactivity into account. This is especially important in radionuclide therapies where very high activities are administered and the radionuclides emit alpha particles, beta particles or low-energy electron and will require absorbed dose c
The authors have developed a porous silicon (P-Si) based duplex antibody microarray platform for simultaneous quantitation of the biomarkers prostate-specific antigen (PSA) and human glandular kallikrein 2 (hK2) in serum. Pore size-controlled P-Si surfaces have an extremely enlarged surface area that enables high-density immobilization of fluorescently labeled antibodies by physical adsorption. Au
Glycosaminoglycans (GAGs) are polysaccharides produced by essentially all mammalian cells. Due to their enormous structural diversity, they are involved in many biological processes both in health and disease, including all stages of tumor progression. GAGs are normally attached to a core protein as a part of a proteoglycan; however, GAG biosynthesis can be induced by compounds composed of a xylos
AbstractPhysical exhaustion can constrain human ascending work capacity and performance during emergency evacuation on stairs. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations during two different strategies: self-preferred pace in three different public stairways in the field, and controlled pace in a laboratory on a stair machin
Background: Patent foramen ovale (PFO) is a contributor to embolic stroke of undetermined source (ESUS). Subgroup analyses from previous studies suggest that anticoagulation could reduce recurrent stroke compared with antiplatelet therapy. We hypothesised that anticoagulant treatment with rivaroxaban, an oral factor Xa inhibitor, would reduce the risk of recurrent ischaemic stroke compared with as
BACKGROUND: Fast-track referral is an increasingly used method for diagnostic evaluation of patients suspected of having cancer. This approach is challenging and not used as often for patients with only nonspecific symptoms. In order to expedite the diagnostics for these patients, we established Sweden's first Diagnostic Center (DC) focusing on outcomes related to diagnoses and diagnostic time int
Lung cancer is a common cancer type associated with poor prognosis. Even in the group of patients with earlystage tumors, for which curative treatment is possible, lung cancer recurrence is frequent. The aim of this thesis was to investigate the potential prognostic role of mutations in tumor specimens, blood-based proteins and circulating tumor DNA.In study I, we performed EGFR mutation detection
Background: Most in vitro studies of potential osteoarthritis (OA) therapies have used cartilage monocultures, even though synovium is a key player in mediating joint inflammation and, thereby, cartilage degeneration. In the case of interleukin-1 (IL-1) inhibition using its receptor antagonist (IL-1Ra), like chondrocytes, synoviocytes also express IL-1 receptors that influence intra-articular IL-1
BACKGROUND: The Genetics of Subsequent Coronary Heart Disease (GENIUS-CHD) consortium was established to facilitate discovery and validation of genetic variants and biomarkers for risk of subsequent CHD events, in individuals with established CHD. METHODS: The consortium currently includes 57 studies from 18 countries, recruiting 185 614 participants with either acute coronary syndrome, stable CHD
Incretin-based therapy is associated with low risk of hypoglycemia in type 2 diabetes mellitus (T2DM) possibly due to its glucose-dependency in stimulating insulin secretion and a sustained glucagon response during hypoglycemia. This is of special relevance when it is combined with insulin or given to elderly patients since both insulin therapy and high age are associated with impaired glucagon co
Checkpoint blockade therapies have changed the clinical management of metastatic melanoma patients considerably, showing survival benefits. Despite the clinical success, not all patients respond to treatment or they develop resistance. Although there are several treatment predictive biomarkers, understanding therapy resistance and the mechanisms of tumor immune evasion is crucial to increase the f
Importance: Better understanding is needed of the degree to which individuals tolerate Alzheimer disease (AD)-like pathological tau with respect to brain structure (brain resilience) and cognition (cognitive resilience). Objective: To examine the demographic (age, sex, and educational level), genetic (APOE-ϵ4 status), and neuroimaging (white matter hyperintensities and cortical thickness) factors
Melanoma of the skin is the sixth most common type of cancer in Europe and accounts for 3.4% of all diagnosed cancers. More alarming is the degree of recurrence that occurs with approximately 20% of patients lethally relapsing following treatment. Malignant melanoma is a highly aggressive skin cancer and metastases rapidly extend to the regional lymph nodes (stage 3) and to distal organs (stage 4)
Chronic pain including temporomandibular disorder (TMD) pain involves a complex interplay between peripheral and central sensitization, endogenous modulatory pathways, cortical processing and integration and numerous psychological, behavioral and social factors. The aim of this study was to compare spectroscopic patterns of N-Acetyl-aspartate (NAA), total creatine (tCr), choline (Cho), myo-inosito
Objectives Biologic agents have dramatically changed treatment of rheumatoid arthritis (RA). To date only scarce head-To-head data exist especially when the biological therapies are given as monotherapy without concomitant disease modifying drugs (DMARDs). Thus the objective of the current study is to evaluate treatment response of all available biological therapies with special focus on utility (
Context. X-ray extragalactic surveys are ideal laboratories for the study of the evolution and clustering of active galactic nuclei (AGN). Usually, a combination of deep and wide surveys is necessary to create a complete picture of the population. Deep X-ray surveys provide the faint population at high redshift, while wide surveys provide the rare bright sources. Nevertheless, very wide area surve
The current plastic system is unsustainable and needs to change. Plastics are mainly produced from fossil feedstock, contributing to greenhouse gas emissions, and low rate of post-consumer recycling results in pollution on land and in oceans with high ecological impact, and huge loss of valuable material. There is an urgent need to find solutions for shifting the raw material base to renewable res
