Stroke is a leading cause of death and long-term neurological deficits worldwide, and no effective treatment is available for the vast majority of the stroke patients. A rapid and persistent activation of multiple and dynamic inflammatory and immune cascades, in and outside the brain, occurs after stroke. These cascades are believed to affect the progression of the cerebral damage, as well as neur

The brain continues to form new neurons throughout life. This process of adult neurogenesis has been thoroughly documented in several species including birds, rodents and humans. Adult neurogenesis is not a global process, but is confined to two subcompartments of the brain; the subventricular zone lining the lateral ventricles, and the subgranular zone (SGZ) in the hippocampal formation. A variet

We investigate quantum dots with Rashba spin-orbit coupling in the strongly-correlated regime. We show that the presence of the Rashba interaction enhances the Wigner localization in these systems, making it achievable for higher densities than those at which it is observed in Rashba-free quantum dots. Recurring shapes in the pair distribution functions of the yrast spectrum, which might be associ

A microscopic nuclear level-density model is presented. The model is a completely combinatorial (micro-canonical) model based on the folded-Yukawa single-particle potential and includes explicit treatment of pairing, rotational and vibrational states. The microscopic character of all states enables extraction of level-distribution functions with respect to pairing gaps, parity and angular momentum

The papilloma- and polyomaviruses are small DNA viruses that infect humans. Some members of these virus families can cause cancer in experimental animals and some are also established as carcinogenic to humans. Detection of specific antibodies to these viruses allows tracking past and present infections to elucidate natural history and association of infection with subsequent disease. As there are

Background and purpose Reports regarding the relationship between delayed surgery and mortality in femoral neck fracture patients are contradictory. We could not find any study in the literature investigating delayed arrival to hospital and delayed surgery as separate factors affecting mortality in femoral neck fracture patients, which was the purpose of our study. Patients and methods We analyzed

In this paper I discuss the dynamics of particle production in high energy reactions. It includes parton cascades and hadronization in e(+)e(-)-annihilation, small x evolution including the Double Leading Log approximation and the BFKL equation, saturation at high densities and the BK equation, and finally the Lund Dipole Cascade model for high energy collisions, which is implemented in the DIPSY

Purpose – There is a need for theory development within the field of humanitarian logistics to understand logistics needs in different stages of a crisis and how to meet these. This paper aims to discuss three dimensions identified in logistics and organization theories and how they relate to three different cases of humanitarian logistics operations – the regional concept of the Internatio

The metabolic syndrome (MS) includes a clustering of metabolic derangements. Low testosterone levels have been shown to be associated with both components of MS and MS per se. As most androgen-related effects are mediated thorough the androgen receptor (AR), we wanted to investigate to which degree the AR CAG and GGN repeat polymorphisms might be related to MS. Sixty-eight men, 60-80 years old, wi

During recent decades we have witnessed growing scientific concern, public debate and media attention concerning the possible adverse effects on humans and wildlife that may result from exposure to a wide range of environmental contaminants. These contaminants are called endocrine disrupters, or endocrine-disrupting compounds (EDCs) and are defined as chemicals that interfere with the function of

Target-specific molecular imaging with radiolabeled antibodies has experienced a rapid growth over the past 20 years, and is now an essential tool to provide information on disease presence and extent. Despite all efforts to detect and control prostate cancer at an early stage, a number of men are still progressing to develop incurable metastatic disease. Because of this, development of new method

Aerodynamic four-way coupling models are necessary to handle two-phase flows with a dispersed phase in regimes in which the particles are neither dilute enough to neglect particle interaction nor dense enough to bring the mixture to equilibrium. We include an aerodynamic particle interaction model within the framework of large eddy simulation together with Lagrangian particle tracking. The particl

We report on the particle assisted synthesis of core-shell AlP-GaP nanowires by use of metal-organic vapor phase epitaxy. The core-shell approach is chosen such as to stabilize the AlP which is highly sensitive to water. The nanowires were investigated by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Raman spectroscopy. These nanowires have an indirect band

This article explores the proposition that a reason for high agricultural productivity in the early nineteenth century was relatively high energy availability from draught animals. The article is based on the collection of extensive new data indicating different trends in draught power availability and the efficiency of its use in different countries of Europe. This article shows that the proposit
