Objective: To compare outcomes for women undergoing two in vitro fertilization (IVF) pregnancies with singletons and women undergoing one IVF twin pregnancy. The concept of single-embryo transfer in IVF has reduced the risks of both maternal and neonatal complications, but there is still a discussion of whether or not twins are a desired outcome of IVF. Design: Registry study. Setting: Not applica

Background: Prostate cancer patients have an increased risk of fractures as a consequence of skeletal metastases and osteoporosis induced by endocrine treatment. Data on incidence of fractures and risks in subgroups of men with prostate cancer are sparse. Our aim with this study is to report the risk of fractures among men with prostate cancer in a nationwide population-based study. Patients and m

Assessment of prognosis after out-of-hospital cardiac arrest (OHCA) is challenging. Cerebral computed tomography (cCT) scans are widely available, but the use in prognostication of comatose OHCA-patients is unclear. We evaluated the prognostic value of cCT in a clinical cohort of OHCA-patients.

Synapsins are a family of phosphoproteins that modulate the release of neurotransmitters from synaptic vesicles. The release of insulin from pancreatic beta-cells has also been suggested to be regulated by synapsins. In this study, we have utilized a knock out mouse model with general disruptions of the synapsin I and II genes [synapsin double knockout (DKO)]. Stimulation with 20 mM glucose increa

Patterns of nonsuicidal self-injury (NSSI) and their association with other psychological difficulties were studied in a community sample of young Swedish adolescents, by a 2-wave longitudinal design with a 1-year interval. Hierarchical cluster analysis at T1 identified eight NSSI subgroups in each gender, of which five were clearly replicated at T2. Among these were a subgroup with generalized hi

Introduction: Meniscal extrusion is thought to be associated with less meniscus coverage of the tibial surface, but the association of radiographic disease stage with quantitative measures of tibial plateau coverage is unknown. We therefore compared quantitative and semi-quantitative measures of meniscus position and morphology in individuals with bilateral painful knees discordant on medial joint

A desire for higher speed and performance in molecular profiling analysis at a reduced cost is driving a trend in miniaturization and simplification of procedures. Here we report the use of a surface acoustic wave (SAW) atomizer for fast sample handling in matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) peptide and protein profiling of Islets of Langerhans, for future type

The diverse cichlid species flocks of the East African lakes provide a classical example of adaptive radiation. Territorial aggression is thought to influence the evolution of phenotypic diversity in this system. Most vertebrates mount hormonal (androgen, glucocorticoid) responses to a territorial challenge. These hormones, in turn, influence behavior and multiple aspects of physiology and morphol

Using data on the entire population in combination with data on almost all individuals in Sweden listed as inventors, we study how the probability of being listed on a patent as inventor is influenced by the density of other future inventors residing in the same region. In this process, we control for demographic and sector effects along with the educational characteristics of parents. This approa

AimTo report on the International Collaboration of Orthopaedic Nursing, a mostly virtual network of orthopaedic nursing organizations across four continents. BackgroundFormed by leaders of three national associations, the collaboration is based on recognition of patient problems and challenges shared by orthopaedic nurses globally. Methods/InitiativesThe Collaboration provides a range of services

We find problems with Vaesen's treatment of the primatological research, in particular his analysis of foresight, function representation, and social intelligence. We argue that his criticism of research on foresight in great apes is misguided. His claim that primates do not attach functions to particular objects is also problematic. Finally, his analysis of theory of mind neglects many distinctio

We investigate long-run stock–bond correlation using a model that combines the dynamic conditional correlation model with the mixed-data sampling approach and allows long-run correlation to be affected by macro-finance factors (historical and forecasts). We use macro-finance factors related to inflation and interest rates, illiquidity, state of the economy, and market uncertainty. Macro-finance fa

Sexual selection against immigrants is a mechanism that can regulate premating isolation between populations but, so far, few field studies have examined whether males can discriminate between immigrant and resident females. Males of the damselfly Calopteryx splendens show mate preferences and are able to force pre-copulatory tandems. We related male mate responses to the ecological characteristic

With the increasing output power of the integrated circuit chips, the heat flux involved is being accordingly increased. In such situation, the air has almost reached its limit of cooling capacity, and thus the liquid cooling technology incorporating microchannel heat sinks is desired to cool the electronic chips in order to remove more heat loads. However, these microchannel heat sinks are often

ABSTACT: Src homology 2 domain-containing tyrosine phosphatase-2 (SHP-2) is an important regulator of cell signaling because of its ability to dephosphorylate receptors of growth factors as well as the cytokines and tyrosine-phosphorylated proteins associated with these receptors. In the current study, we used four different prostate cancer cell lines: PC3, DU145, LNCaP and LNCaP-IL6+. Tumor speci

Reactive oxygen species (ROS) and reactive nitrogen species (RNS) participate in pathological tissue damage. Mitochondrial manganese superoxide dismutase (MnSOD) normally keeps ROS and RNS in check. During development of mangafodipir (MnDPDP) as a magnetic resonance imaging (MRI) contrast agent, it was discovered that MnDPDP and its metabolite manganese pyridoxyl ethyldiamine (MnPLED) possessed SO

The optimum surface charge on a thin wire antenna is computed using a variational formulation in the low-frequency limit. This charge and its corresponding current are compared with simulation results for self resonant structures. The comparison shows that the currents and charges on self resonant structures resemble those in the static limit to a great extent.
