The aim of the work presented in this thesis was to identify the ultrasound methods and ultrasound features that are most useful for the prediction of endometrial cancer in patients with postmenopausal bleeding and sonographic endometrial thickness 4.5 mm or more. The grey-scale ultrasound variable that best predicted malignancy was heterogeneous endometrial echogenicity (area under the receiver o

Context: Due to early detection strategies, prostate cancer is diagnosed early in its natural history. It remains unclear whether all patients diagnosed with prostate cancer warrant radical treatment or may benefit from delayed intervention following active surveillance. Objective: A systematic review of active surveillance protocols to investigate the inclusion criteria for active surveillance an

This study is the first to present evidence of the return to leisure sports in the job hiring process by sending fictitious applications to real job openings in the Swedish labor market. In the field experiment job applicants were randomly given different information about their type and level of leisure sports. Applicants who signaled sports skills had a significantly higher callback rate of abou

In this work we use low-energy electron microscopy, x-ray photoemission electron microscopy, and x-ray photoelectron spectroscopy to study how the excess Si at the graphene-vacuum interface reorders itself at high temperatures. We show that silicon deposited at room temperature onto multilayer graphene films grown on the SiC(000 (1) over bar) rapidly diffuses to the graphene-SiC interface when hea

OBJECTIVE. Screening examination for retinopathy of prematurity is distressing and painful. The aim of the present study was to investigate whether a Newborn Individualized Developmental Care and Assessment Program intervention during a retinopathy of prematurity examination results in less adverse behavioral, pain, and stress responses as compared with standard care. METHODS. The first 2 eye exam

The measurement of single leptons from the semi-leptonic decay of heavy-flavor hadrons has long been a means for studying heavy-quark production. PHENIX has measured single muons in pp collisions at forward rapidity and single electrons in both pp and AuAu collisions at mid-rapidity at . The most recent PHENIX single lepton results are presented in the context of state-of-the-art pQCD calculations

A review of literature related to fire evacuation in underground transportation systems, e.g., tunnels and subway stations, was carried out with the objectives (1) to identify a theoretical framework that can help understand of human behaviour in the event of a fire in underground transportation systems, (2) to use the theoretical framework to analyse and to identify problems related to fire evacu

The authors tested the hypothesis that experiencing sexual coercion and engaging in sexually coercive behavior are positively associated in a representative sample totaling almost 4,000 Swedish or Norwegian male high school students (estimated response rate 80%). In both surveys, youths who had experienced sexual coercion were approximately three times more likely to engage in sexually coercive be

Nasopharyngeal carcinoma (NPC) is common among southern Chinese including the ethnic Cantonese population living in Hong Kong. Epstein-Barr virus (EBV) infection is detected in all undifferentiated type of NPC in this endemic region. Establishment of stable and latent EBV infection in premalignant nasopharyngeal epithelial cells is an early event in NPC development and may contribute to its pathog

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled p+p collisions. These measurements indicate that charm and bottom quarks interact with the hot dense matter produced in heavy-ion collisions much more than expected. Here we extend these studies to two-particle correlations w

Digital holographic microscopy (DHM) has emerged as a powerful non-invasive tool for cell analysis. It has the capacity to analyse multiple parameters simultaneously, such as cell- number, confluence and phase volume. This is done while cells are still adhered and growing in their culture flask. The aim of this study was to investigate whether DHM was able to monitor drug-induced cell cycle arrest

By simultaneous coherent anti-Stokes Raman scattering (CARS) and 2-photon fluorescence microscopy of Thioflavin-S stained Alzheimer´s diseased human brain tissues, we show evidence of lipid deposits co-localizing with fibrillar β-amyloid (Aβ) plaques. Two lipid morphologies can be observed; lamellar structures and coalescing macro-aggregates of sub-micron sizes to ~25 μm. No significant lipid depo

When fruits ripen, microbial communities start a fierce competition for the freely available fruit sugars. Three yeast lineages, including baker's yeast Saccharomyces cerevisiae, have independently developed the metabolic activity to convert simple sugars into ethanol even under fully aerobic conditions. This fermentation capacity, named Crabtree effect, reduces the cell-biomass production but pro

The production of string rotation and pattern dynamics through the generation of text must build on the presence of a reversible rotary motor which has a synthesizing capacity. This is the discovered AaO-mechanism, which has the power to capture synthesis through emerging AaO-rings. Further, the transcription through the Functional Clause (FC) provides the foundation for their differentiation and

Background: Three genomewide metastudies have recently reported associations with self-reported allergic rhinitis and allergic sensitization. The three studies together identified a set of 37 loci but showed low concordance. This study investigates the reproducibility of the detected single nucleotide polymorphism (SNP) associations in an extensively characterized longitudinal cohort, BAMSE. Metho

Photosynthetic reaction centers convert sunlight into a transmembrane electrochemical potential difference, providing chemical energy to almost all life on earth. Light energy is efficiently transferred through chromophore cofactors to the sites, where charge separation occurs. We applied two-dimensional electronic spectroscopy to assess the role of coherences in the photoresponse of the bacterial
