New guidelines from the European Society of Cardiology (ESC) for the management of acute coronary syndromes in patients presenting without persistent ST-segment elevation (NSTEMI-ACS) stress the importance of more individualized diagnostics and therapy based on the patients' initial risk profile balancing risk of ischemia with risk of bleeding. In this commentary, the Working Group on Coronary Art

The monoamines, serotonin, dopamine, norepinephrine, epinephrine and histamine, play a critical role in the function of the hypothalamic- pituitary-adrenal axis and in the integration of information in sensory, limbic, and motor systems. The primary mechanism for termination of monoaminergic neurotransmission is through reuptake of released neurotransmitter by Na+,CI-dependent plasma membrane tran

Recent studies have shown increased concentration of fetal hemoglobin (HbF) in pre-eclamptic women. Plasma hemopexin (Hpx) and alpha-1-microglobulin (A1M) are hemoglobin scavenger proteins that protect against toxic effects of free heme released in the hemoglobin degradation process. We used an enzyme-linked immunosorbent assay to analyze maternal plasma Hpx and A1M concentrations at 12–14, 18–20

Background: Age, sex, and body constitution may affect the shedding of membrane bound angiotensin-converting enzyme 2 (mACE2) and lead to a relative mACE2 deficiency. However, it is unclear if differences, reflected by serum renin levels, exist in the basal renin-angiotensin-system (RAS) between children and adults, boys, and girls as well as young women and young men. Furthermore, it remains to b

Cells of the exocrine pancreas produce digestive enzymes potentially harmful to the intestinal mucosa. Dopamine has been reported to protect against mucosal injury. In looking for the source of dopamine in the small intestine, we found that the duodenal juice contains high levels of dopamine and that the pancreas itself has a high dopamine [and dihydroxyphenylalanine (dopa)] content that does not

We used in situ hybridization histochemistry to study the expression of the two vesicular monoamine transporters (VMAT1 and VMAT2) during embryonic development in the rat. In the adult rat VMAT2 is present exclusively in neuronal tissues and VMAT1 is present in the adrenal medulla and in certain intestinal endocrine cells. We found that both transporter molecules are more widely expressed during d

We used in situ hybridization histochemistry to study the expression of the mRNA of the two vesicular monoamine transporters (VMAT1 and VMAT2) during embryonic and postnatal development of the central nervous system (CNS) int he rat. In the adult rat, VMAT2 mRNA is present exclusively in monoaminergic cell groups of the CNS and VMAT1 mRNA was reported to be present in the adrenal medulla and certa

We investigate the rotational properties of a dipolar Bose-Einstein condensate trapped in a toroidal geometry. Studying the ground states in the rotating frame and at fixed angular momenta, we observe that the condensate acts in distinctly different ways depending on whether it is in the superfluid or in the supersolid phase. We find that intriguingly, the toroidal dipolar condensate can support a

In this essay, we discuss basic orientations and ways of being among us, the academics, especially in the context of research. Using German poet, scholar and author Friedrich Schiller’s distinction between ‘der philosophische Kopf’ (‘philosophical mind’) and ‘Brotgelehrte’ (‘bread-fed scholar’), we contrast ideal-typical figures in academia. We find these forgotten 18th-century characters inspirat

A growing body of evidence suggests that serotonin plays an important role in the early development of both neural and non-neural tissues from vertebrate and invertebrate species. Serotonin is removed from the extracellular space by the cocaine- and antidepressant-sensitive serotonin transporter, thereby limiting its action on receptors. In situ hybridization histochemistry was used to delineate s

Serotonin has been shown to affect the development of the mammalian nervous system. The serotonin transporter is a major factor in regulating extracellular serotonin levels. Using in situ hybridization histochemistry the rat serotonin transporter messenger RNA was localized during embryogenesis, the first four weeks postnatally and adulthood. Three general classes of serotonin transporter messenge

We and others have previously identified serotonin transporter mRNA throughout the trigeminal system in the whisker region, trigeminal ganglion, trigeminal nucleus and thalamic relay stations. In order to further implicate a role for the serotonin transporter in this sensory system, we have now characterized serotonin transporter gene expression and function in primary cultures from the rat snout,

We present a combined experimental and theoretical study of the two-dimensional electron states at the iridium-silicide surface of the antiferromagnet GdIr2Si2 above and below the Néel temperature. Using angle-resolved photoemission spectroscopy (ARPES) we find a significant spin-orbit splitting of the surface states in the paramagnetic phase. By means of ab initio density-functional-theory (DFT)

Models can be used as integrative devices in scientific practice, as well as at the science-policy interface, in many different ways. In this chapter, three ways in which models can function as such devices are discussed. As themselves, the locus of the integration of different kinds of epistemic components, as coupled and modular structures that integrate other models, and as boundary objects tha

Aims: Clinical trials have demonstrated that a reduction in low-density lipoprotein cholesterol (LDL-C) reduces cardiovascular (CV) events. This has, however, not yet been shown in a real-world setting. We aimed to investigate the association between LDL-C changes and statin intensity with prognosis after a myocardial infarction (MI). Methods and results: Patients admitted with MI were followed fo

Urokinase plasminogen activator (u-PA) plays a pivotal role in tissue degradation during tumor spread and metastasis. We have quantitated u-PA in tissue homogenates of 31 serous ovarian tumors and localized u-PA and its mRNA in tissue sections of 26 serous ovarian tumors. The content of u-PA was higher in malignant than in benign tumors, with the highest levels being found in poorly differentiated

1. Dopamine (DA) is a protective agent in the gastrointestinal (GI) tract in both rats and humans. Therefore, we have studied the site of DA production in rat and human GI tract using a variety of techniques, including immunocytochemistry (ICC), in situ hybridization histochemistry, reverse transcription-polymerase chain reaction, HPLC, western blotting and immunoelectron microscopy. 2. We found v

A Mobile stroke unit (MSU) is a type of ambulance deployed to promote the rapid delivery of stroke care. We present a computational study using a time to treatment estimation model to analyze the potential benefits of using MSUs in Sweden’s Southern Health Care Region (SHR). In particular, we developed two scenarios (MSU1 and MSU2) each including three MSUs, which we compared with a baseline scena

Even though co‐parenthood is one of the most significant close personal relationships that people can have, there is relatively little philosophical work on the moral duties that co‐parents owe each other. This may be due to the increasingly questionable assumption, still common in our societies, that co‐parenthood arises naturally from marriage or romantic coupledom and thus that commitment to a

Studies of thermally induced transport in nanostructures provide access to an exciting regime where fluctuations are relevant, enabling the investigation of fundamental thermodynamic concepts and the realization of thermal energy harvesters. We study a serial double quantum dot formed in an InAs/InP nanowire coupled to two electron reservoirs. By means of a specially designed local metallic joule-
