Predictive Value of Four Kallikrein Markers for Pathologically Insignificant Compared With Aggressive Prostate Cancer in Radical Prostatectomy Specimens: Results From the European Randomized Study of Screening for Prostate Cancer Section Rotterdam

Background: Treatment decisions can be difficult in men with low-risk prostate cancer (PCa). Objective: To evaluate the ability of a panel of four kallikrein markers in blood-total prostate-specific antigen (PSA), free PSA, intact PSA, and kallikrein-related peptidase 2-to distinguish between pathologically insignificant and aggressive disease on pathologic examination of radical prostatectomy (RP

The pathway of obstructed labour as perceived by communities in south-western Uganda: a grounded theory study.

BACKGROUND: Obstructed labour is still a major cause of maternal and perinatal morbidity and mortality in Uganda, where many women give birth at home alone or assisted by non-skilled birth attendants. Little is known of how the community view obstructed labour, and what actions they take in cases where this complication occurs. OBJECTIVE: The objective of the study was to explore community members

Is it possible to predict the outcome of an anterior cruciate ligament injury?

This thesis centers on a well-studied cohort of 100 patients, which received a treatment regimen of initial rehabilitation and activity modification to cope with Anterior Cruciate Ligament (ACL) injury. The data, collected prospectively and longitudinally, cover a span of 15 years after initial injury. The overall aim of this thesis is to describe the course of an ACL injury treated with rehabilit

Some open questions in TDDFT: Clues from lattice models and Kadanoff-Baym dynamics

Two aspects of TDDFT, the linear response approach and the adiabatic local density approximation, are examined from the perspective of lattice models. To this end, we review the DFT formulations on the lattice and give a concise presentation of the time-dependent Kadanoff-Baym equations, used to asses the limitations of the adiabatic approximation in TDDFT. We present results for the density respo

Gestational Age at Birth and Mortality in Young Adulthood

Context Preterm birth is the leading cause of infant mortality in developed countries, but the association between gestational age at birth and mortality in adulthood remains unknown. Objective To examine the association between gestational age at birth and mortality in young adulthood. Design, Setting, and Participants National cohort study of 674 820 individuals born as singletons in Sweden in 1

Vibronic origin of long-lived coherence in an artificial molecular light harvester.

Natural and artificial light-harvesting processes have recently gained new interest. Signatures of long-lasting coherence in spectroscopic signals of biological systems have been repeatedly observed, albeit their origin is a matter of ongoing debate, as it is unclear how the loss of coherence due to interaction with the noisy environments in such systems is averted. Here we report experimental and

User involvement in service delivery predicts outcomes of assistive technology use: A cross-sectional study in Bangladesh

Background: Knowledge about the relation between user involvement in the provision of assistive technology and outcomes of assistive technology use is a prerequisite for the development of efficient service delivery strategies. However, current knowledge is limited, particularly from low-income countries where affordability is an issue. The objective was therefore to explore the relation between o

Burden of Risk Alleles for Hypertension Increases Risk of Intracerebral Hemorrhage

Background and Purpose-Genetic variation influences risk of intracerebral hemorrhage (ICH). Hypertension (HTN) is a potent risk factor for ICH and several common genetic variants (single nucleotide polymorphisms [SNPs]) associated with blood pressure levels have been identified. We sought to determine whether the cumulative burden of blood pressure-related SNPs is associated with risk of ICH and p

Genetic Variants in Hormone-Related Genes and Risk of Breast Cancer

Sex hormones play a key role in the development of breast cancer. Certain polymorphic variants (SNPs and repeat polymorphisms) in hormone-related genes are associated with sex hormone levels. However, the relationship observed between these genetic variants and breast cancer risk has been inconsistent. We conducted a case-control study nested within two prospective cohorts to assess the relationsh

Patterns of alcohol consumption and risky sexual behavior: a cross-sectional study among Ugandan university students.

As reflected in elevated rates of sexually transmitted infections, there is a high prevalence of risky sexual behavior among Ugandan university students. It has been assumed that alcohol contributes to risky sexual behavior. However, perhaps owing to methodological issues, this relationship has found only mixed support in empirical research. The present study analyzes the association between alcoh

Probing Strain in Bent Semiconductor Nanowires with Raman Spectroscopy.

We present a noninvasive optical method to determine the local strain in individual semiconductor nanowires. InP nanowires were intentionally bent with an atomic force microscope and variations in the optical phonon frequency along the wires were mapped using Raman spectroscopy. Sections of the nanowires with a high curvature showed significantly broadened phonon lines. These observations together

Temperature dependent nonlinear response of quantum cascade structures

Current response and gain spectrum of a terahertz quantum cascade laser is analyzed at different temperatures by a nonequilibrium Green's functions approach. The simulations are compared to recent results of time domain spectroscopy. Being able to retrieve higher harmonics of the response function, nonlinear phenomena in quantum cascade lasers are studied theoretically. For different temperatures,

Electrochemical behavior and application of Prussian blue nanoparticle modified graphite electrode

Prussian blue nanoparticles (PBNPs) were immobilized on the surface of a graphite electrode (GE) through a simple adsorption route and then the modified surface was covered with a layer of Nafion. The electrochemical behavior of the resulting sensor was investigated using cyclic voltammetry and chronoamperometry. The sensor showed good electrocatalytic activity toward hydrogen peroxide reduction,

Quantitative measurement of fluorescence brightness of single molecules

Single-molecule fluorescence spectroscopy and imaging probe many characteristics of the fluorescence from individual molecules like relative intensity, polarization, lifetime and spectrum. However, such an important and fundamental parameter as absolute fluorescence intensity (or in other words fluorescence brightness), which is proportional to the absorption cross section and fluorescence quantum

Cancer of unknown primary (CUP): does cause of death and family history implicate hidden phenotypically changed primaries?

Cancer of unknown primary (CUP) is diagnosed at the metastatic stage. We aimed to identify hidden primary cancers in CUP patients by comparison with cancers in family members. We take use of the fact that the cause of death in CUP patients is often coded as the cancer in the organ of fatal metastasis. Forty-one thousand five hundred and twenty-three CUP patients were identified in the Swedish Fami

HLA Class I and Genetic Susceptibility to Type 1 Diabetes Results From the Type 1 Diabetes Genetics Consortium

OBJECTIVE-We report here genotyping data and type 1 diabetes association analyses for HLA class I loci (A, B, and C) on 1,753 multiplex pedigrees from the Type 1 Diabetes Genetics Consortium (T1DGC), a large international collaborative study. RESEARCH DESIGN AND METHODS-Complete eight-locus HLA genotyping data were generated. Expected patient class I (HLA-A, -B, and -C) allele frequencies were cal
