Purpose: In addition to genomic signaling, it is accepted that estrogen receptor-alpha (ER alpha) has nonnuclear signaling functions, which correlate with tamoxifen resistance in preclinical models. However, evidence for cytoplasmic ER localization in human breast tumors is less established. We sought to determine the presence and implications of nonnuclear ER in clinical specimens. Experimental D

Introduction: We studied the release of propranolol hydrochloride (PHCl), a water-soluble amphiphilic drug, from monoolein (MO)/water and phytantriol/water systems. Methods: We related the dissolution profiles with phase behavior and viscosity of the different liquid crystalline phases. Diolein has been added aiming to stabilize the cubic phases and thus preventing formation of less viscous (lamel

Abstract Conclusion: Risk factors associated with increased carriage rates are the same in children with recurrent acute otitis media (rAOM) as in healthy children. These are also known to be risk factors for the development of AOM itself. Objectives: The aim of this study was to describe risk factors for nasopharyngeal carriage in a cohort of young children at high risk of developing rAOM. Method

Purpose: Induced pluripotent stem cells (iPSCs) improve behavior and form neurons after implantation into the stroke-injured adult rodent brain. How the aged brain responds to grafted iPSCs is unknown. We determined survival and differentiation of grafted human fibroblast-derived iPSCs and their ability to improve recovery in aged rats after stroke. Methods: Twenty-four months old rats were subjec

Terrestrial cosmogenic nuclide dating in combination with detailed landform mapping in the Kongsf-jordhallet area, NW Svalbard, have provided new insight on configuration, dynamics, and deglaciation of the Late Weichselian Kongsfjorden ice stream. The minimum Late Weichselian ice surface elevation in Kongsfjorden was >449 m a.s.l. indicating considerably thicker ice and a steeper surface gradient

Investigate in a cross-sectional study time-dependent changes of synovial fluid type II collagen epitope C2C concentrations after knee injury and correlate to other joint injury biomarkers.

Context: Postprandial glucose homeostasis is regulated through the secretion of glucagon-like peptide 1 (GLP-1) through stimulation of insulin secretion and inhibition of glucagon secretion. However, how these processes dynamically adapt to demands created by caloric challenges achieved during daily life is not known. Objective: To explore adaptation of incretin and islet hormones after mixed meal

Solar energy conversion in photovoltaics or photocatalysis involves light harvesting, or sensitization, of a semiconductor or catalyst as a first step. Rare elements are frequently used for this purpose, but they are obviously not ideal for large-scale implementation. Great efforts have been made to replace the widely used ruthenium with more abundant analogues like iron, but without much success

Although parasites are important regulatory factors in animal populations, basic knowledge on their fauna in many vertebrate taxa is lacking. In particular, parasite infections of primate species have gained little attention. Here, I present data on the gastro-intestinal fauna of a population of wild red-fronted lemurs (Eulemur fulvus rufus; Primates: Lemuriformes) monitored over a total of 8 mo d

Background: Patients with ostium secundum atrial septal defects (ASDs) were studied to determine the prevalence of Selvester anteroseptal myocardial infarction QRS points, and to test the hypothesis that there is a relationship between these criteria and thinning and/or scarring of the inter-ventricular septum (IVS). Methods: Demographic, electrocardiographic (ECG), and cardiac magnetic resonance

Protein dynamics on the microsecond-millisecond time scales often play a critical role in biological function. NMR relaxation dispersion experiments are powerful approaches for investigating biologically relevant dynamics with site-specific resolution, as shown by a growing number of publications on enzyme catalysis, protein folding, ligand binding, and allostery. To date, the majority of studies

Achieving control of the crystal structure is essential in III-V nanowires, since twin defects, stacking faults and uncontrolled zincblende-wurtzite polytypism could have detrimental effects on the physical properties. In addition, precise control of the crystal phases also opens up the possibility of homomaterial bandgap engineering. Here, we show by ex situ chemical analysis of the alloy seed pa

The release of lactose (hydrophilic) from polymer tablets made with hydrophobically modified poly(acrylic acid) (HMPAA) have been studied and compared it to the release of ibuprofen, a hydrophobic active substance. Lactose is one of the most used excipients for tablets, but lactose release has not been widely studied. One reason could be a lack of good analytical tools. A novel biosensor with cell

Sexual conflicts and their evolutionary outcomes may be influenced by population-specific features such as mating system and ecological context; however, very few studies have investigated the link between sexual conflict and mating system. The self-compatible, mixed-mating hermaphrodite Collinsia heterophylla (Plantaginaceae) is thought to exhibit a sexual conflict over timing of stigma receptivi

Laser-induced incandescence (LII) as a diagnostic technique is based on rapid heating of soot particles to temperatures of several thousand Kelvin and subsequent detection of the thermal radiation from the laser-heated particles. At such high temperatures, soot sublimation effects must be considered when estimating uncertainties in LII measurements. In this work we have investigated the use of var

Objective: to explore midwives' awareness of and clinical experience regarding domestic violence among pregnant women in southern Sweden. Design: an inductive qualitative design, using focus groups interviews. Setting: midwives with experience of working in antenatal care (ANC) units connected to two university hospitals in southern Sweden. Participants 16 midwives recruited by network sampling an

Abstract Objective. This study examined whether age, gender, and comorbidity were of importance for an individual's choice of listing with either a public or a private primary health care (PHC) practice. Design and setting. The study was a register-based closed cohort study in one private and one public PHC practice in Blekinge County in southern Sweden. Subjects. A cohort (12 696 individuals) was

We propose a new dynamic hybrid logic to reason about social networks and their dynamics building on the work of “Logic in the Community” by Seligman, Liu and Girard. Our framework distinguishes between the purely private sphere of agents, namely their mental states, and the public sphere of their observable behavior, i.e., what they seem to believe. We then show how such a distinction allows our
