It is well known that nonirradiated cells can exhibit radiation damage (bystander effect), and recent findings have shown that nonirradiated cells may help protect irradiated cells (rescue effect). These findings call into question the traditional view of radiation response: cells cannot be envisioned as isolated units. Here, we investigated traditional colony formation assays to determine if they

Plant-emitted biogenic volatile organic compounds (BVOCs) are a large group of hydrocarbons released by plant leaves, bark, flowers and fruits into the atmosphere and from plant roots into the soil. BVOCs have important physiological and ecological functions, such as mediating within-plant and plant-plant communication, defense against herbivores attack, protection against heat or other oxidative

Background: Childhood adversity (CA) leads to greater vulnerability for psychopathology by causing structural as well as functional brain abnormalities. Recent findings on gray matter effects point towards the importance of identifying CA outcome as a function of different CA types, varying in the dimensions of threat and deprivation. Using diffusion tensor imaging, we investigate whether differen

Institutions for prevention and resolution of labor market conflicts were introduced all over the world in the early twentieth century. In this paper we analyze the impact of mediation on compromise outcomes in Swedish labor market conflicts, using a dataset of geo-coded strikes and lockouts from 1907 to 1927. Causality is identified by using the distance from the mediator's residence to the confl

Enriched environments elicit brain plasticity in animals. In humans it is unclear which environment is enriching. Living in a city has been associated with increased amygdala activity in a stress paradigm, and being brought up in a city with increased pregenual anterior cingulate cortex (pACC) activity. We set out to identify geographical characteristics that constitute an enriched environment aff

Background: Most studies of brain structure and function, and their relationships to cognitive ability, have relied on inter-individual variability in magnetic resonance (MR) images. Intra-individual variability is often ignored or implicitly assumed to be equivalent to the former. Testing this assumption empirically by collecting enough data on single individuals is cumbersome and costly. We coll

Holst-Ekströms bidrag är en essä som handlar om ett antal franska slott, från 1700 och 1800-talen, om minnets roll i förhållande till arkitekturen och litteraturen. Den behandlar också konstnären Marie Anderssons specifika relation till fotografi och arkitektur.This essay is about a number of French castles, from the 18th and 19th centuries, it concerns the rôle of architecture in relation to memory and litterature. It is also about the specific works of artist Marie Andersson, and how she photography and architecture.
