Label retention and stem cell marker expression in the developing and adult prostate identifies basal and luminal epithelial stem cell subpopulations

Background: Prostate cancer is the second most frequent cancer among males worldwide, and most patients with metastatic disease eventually develop therapy-resistant disease. Recent research has suggested the existence of cancer stem-like cells, and that such cells are behind the therapy resistance and progression. Methods: Here, we have taken advantage of the relatively quiescent nature of stem ce

Capital Taxation and Investment : Matching 100 Years of Wealth Inequality Dynamics

Using a parsimonious, analytically tractable dynamic model, we are able to explain up to 100 years of the available data on the dynamics of top-wealth shares for several countries. We build a micro-founded model of heterogeneous agents in which - in addition to stochastic returns on investment - individuals disagree marginally on their expectations of future returns and thus hold different asset p

Testosterone suppression with a unique form of leuprorelin acetate as a solid biodegradable implant in patients with advanced prostate cancer : results from four trials and comparison with the traditional leuprorelin acetate microspheres formulation

Background: There are two slow-release ready-to-use forms of leuprorelin acetate (1-month and 3-month) that are available as solid, biodegradable implants for the treatment of advanced, hormone-sensitive prostate cancer. These implants have been shown to be as effective as traditional leuprorelin acetate microspheres for achieving successful testosterone suppression (≥0.5 ng/ml) and lowering prost

No time to talk! Teachers' perception of workplace communication

Teachers’ perception of organizational communication was assessed with a tailored questionnaire sampling 401 primary and lower secondary school teachers from two municipalities in Sweden (response rate 61 %). Overall, the teachers were satisfied with the workplace communication climate, the communication structure, and collegial communication, while time for communication, was reported deficient.

External Validation of Two Classification and Regression Tree Models to Predict the Outcome of Inpatient Cardiopulmonary Resuscitation

Objective: To prospectively validate a previously developed classification and regression tree (CART) model that predicts the likelihood of a good outcome among patients undergoing inpatient cardiopulmonary resuscitation. Design: Prospective validation of a clinical decision rule. Setting: Skåne University Hospital in Malmo, Sweden. Patients: All adult patients (N = 287) experiencing in-hospital c

Why the Social Sciences are Irreducible

It is often claimed that the social sciences cannot be reduced to a lower-level individualistic science. The standard argument for this position (usually labelled explanatory holism) is the Fodorian multiple realizability argument. Its defenders endorse token-token(s) identities between “higher-level” social objects and pluralities/sums of “lower-level” individuals (a position traditionally called

Circulating Tumor Cells as a Marker for Progression-free Survival in Metastatic Castration-naïve Prostate Cancer

BACKGROUND: Analysis of circulating tumor cells (CTC) is a promising prognostic marker in castration-resistant prostate cancer (CRPC). The aim of this study was to investigate CTC detection and phenotyping as prognostic biomarkers for response to primary androgen deprivation therapy (ADT) of metastatic prostate cancer (PC). METHODS: PC patients presenting with a prostate specific antigen (PSA) >80

Enhanced absorption of long-chain polyunsaturated fatty acids following consumption of functional milk formula, pre-digested with immobilized lipase ex vivo, in an exocrine pancreatic insufficient (EPI) pig model

An exocrine pancreatic insufficient (EPI) pig model was used in the study. The effects of milk formula pre-digestion with immobilized microbial lipase, on the absorption and tissue accretion of long chain polyunsaturated fatty acids (LCPUFA) were assessed. Thirteen male EPI pigs, 10 weeks of age, were used in the study. Six healthy pigs, 6 weeks of age, were used as controls. The pigs were fed eit

Adaptive sequence evolution is driven by biotic stress in a pair of orchid species (Dactylorhiza) with distinct ecological optima

The orchid family is the largest in the angiosperms, but little is known about the molecular basis of the significant variation they exhibit. We investigate here the transcriptomic divergence between two European terrestrial orchids, Dactylorhiza incarnata and Dactylorhiza fuchsii, and integrate these results in the context of their distinct ecologies that we also document. Clear signals of lineag

Elimination of Lateral Resistance and Current Crowding in Large-Area LEDs by Composition Grading and Diffusion-Driven Charge Transport

Gallium nitride based light-emitting diodes (LEDs) are presently fundamentally transforming the lighting industry, but limitations in the materials and fabrication methods of LEDs introduce substantial challenges to their future development. Among the remaining key bottlenecks of GaN LEDs are the resistive losses and current crowding that strongly increase the heat generation at high powers. In th

The effect of local land-use changes on floristic diversity during the past 1000 years in southern Sweden

The relationship between land-use and floristic diversity in the landscape, for the last millennia, is analysed from two small lakes in southern Sweden. Pollen analysis and the Local Vegetation Estimates (LOVE) model are used to quantify land-cover at local scales with 100-year time windows. Floristic richness is estimated using palynological richness, and we introduce LOVE-based evenness as a pro

Crystal structure refinement of chromites from two achondrites, their T-f(O2) conditions, and implications

Six Cr-spinel grains from NWA 6077 brachinite-like and NWA 725 winonaite achondrites have been studied by single-crystal X-ray diffraction and structural refinement. From a chemical point of view, spinels from NWA 6077 show Cr/(Cr + Al) (i.e., Cr#) and Mg/(Mg + Fe2+) (i.e., Mg#) values similar to other brachinites, while the Cr# of NWA 725 is lower than that of literature winonaites. Spinels from

Entropy solutions of a scalar conservation law modeling sedimentation in vessels with varying cross-sectional area

The sedimentation of an ideal suspension in a vessel with variable cross-sectional area can be described by an initial-boundary value problem for a scalar nonlinear hyperbolic conservation law with a nonconvex flux function and a weight function that depends on spatial position. The sought unknown is the local solids' volume fraction. For the most important cases of vessels with downward-decreasin

User Body Effect on Phased Array in User Equipment for the 5G mmWave Communication System

The millimeter-wave phased array in the user equipment (UE) for 5G communication is studied in this letter. In particular, the body effect on the phased array in the UE at 15 GHz is investigated with the 3-D measurement data, and its impact on some key parameters for phased array in the UE, such as the total scan pattern, the coverage efficiency, and the probability of detection, are analyzed.

Zircon growth during progressive recrystallization of Gabbro to Garnet Amphibolite, Eastern Segment, Sveconorwegian orogen

The interpretation of whether a dated metamorphic zircon generation grew during the prograde, peak or retrograde stage of a metamorphic cycle is critical to geological interpretation. This study documents a case at Herrestad, in the eastern part of the 1±0 Ga Sveconorwegian Province, involving progressive metamorphic recrystallization of gabbro to garnet amphibolite and associated behaviour of Zr-

Regionalized Development and Maintenance of the Intestinal Adaptive Immune Landscape

The intestinal immune system has the daunting task of protecting us from pathogenic insults while limiting inflammatory responses against the resident commensal microbiota and providing tolerance to food antigens. This role is particularly impressive when one considers the vast mucosal surface and changing landscape that the intestinal immune system must monitor. In this review, we highlight regio

Design and control of integrated chromatography column sequences

To increase the productivity in biopharmaceutical production, a natural step is to introduce integrated continuous biomanufacturing which leads to fewer buffer and storage tanks, smaller sizes of integrated unit operations, and full automation of the operation. The main contribution of this work is to illustrate a methodology for design and control of a downstream process based on integrated colum
