Anhedoni, minskad motivation att uppleva lust, är associerad med förändringar i belöningssystemet. Belägen i ventrala striatum utgör den bilaterala nucleus accumbens (NAcc) den centrala noden i detta nätverk, där dopamin agerar som huvudsaklig excitatorisk neurotransmitter. Studier med funktionell magnetresonanstomografi (fMRI) har visat att aktiviteten i ventrala striatum minskar under belöningsbAnhedonia, reduced motivation to experience pleasure, is associated with alterations in the circuitry of the reward system. Located in the ventral striatum, the bilateral nucleus accumbens (NAcc) is the central hub of this network where dopamine acts as the main excitatory neurotransmitter. Studies using functional magnetic resonance imaging (fMRI) found that activity in the ventral striatum is de

Biogenic volatile organic compounds (BVOC), such as isoprene and monoterpenes, play an important role in atmospheric processes. BVOC species are oxidized in the atmosphere and influence levels of ozone. The less volatile amongst the BVOC and their oxidation products are important for the formation and growth of secondary biogenic aerosol. In this way, the Earth's radiation balance is affected. Geo

Power to the People examines the varied but interconnected relationships between energy consumption and economic development in Europe over the last five centuries. It describes how the traditional energy economy of medieval and early modern Europe was marked by stable or falling per capita energy consumption, and how the First Industrial Revolution in the eighteenth century--fueled by coal and st

In the brain, focal ischemia results in a local region of cell death and disruption of both local and remote functional neuronal networks. Tissue reorganization following stroke can be limited by factors such as extracellular matrix (ECM) molecules that prevent neuronal growth and synaptic plasticity. The brain's ECM plays a crucial role in network formation, development, and regeneration of the c

The finely-tuned increases and decreases in the intracellular calcium levels in myocytes ultimately regulate the contraction and relaxation of the heart. Therapeutic agents can improve or interfere with this delicate balance. Calcium sensitizers enhance cardiac contraction by improving the use of calcium that is available, rather than by inundating the cell with excessive calcium, as is the case w

The dramatic increase in accessibility to sequencing technologies has opened new avenues into studying different processes, cells, and animal models. In the amphibian models used for regeneration research, these new datasets have uncovered a variety of information about what genes define the regenerating limb as well as how genes and cells change over the course of regeneration. The accumulation o

Question: what do the following statistics have in common? The second-largest (and growing) source of climate pollution in Europe. The leading killer of children in both the US and Europe. A principal cause of stress-inducing noise pollution and life-shortening air pollution in European cities. A leading driver of the widening gap between rich and poor urban residents.Answer: the vehic

Objective: To assess the mid-term outcomes and feasibility of branched endovascular repair (b-EVAR) of ruptured thoracoabdominal aortic aneurysms (rTAAAs). Methods: All patients undergoing b-EVAR of rTAAAs between 2011 and 2016 were included. Pre-, intra and postoperative imaging was reviewed to assess technical success, outcomes, and feasibility of b-EVAR in the emergent setting. Results: Eleven

Inflation targeting is a common monetary policy regime. Inflation targets are often flexible in the sense that the central bank allows inflation to temporarily deviate from the target to avoid causing unnecessary volatility in the real economy. In this paper, we propose modeling the degree of flexibility using an autoregressive fractionally integrated moving average (ARFIMA) model. Assuming that
