    Abstract Epoxyeicosatrienoic acids (EETs) build a family consisting of four arachidonic acid derived regioisomers that are generated by P450 epoxygenases. In the past years, growing interest in influencing EET level arose since EETs possess numerous beneficial effects in the cardiovascular system, for example, vasodilation, anti-inflammation and elicit renal and myocardial protection. Because EETs are primarily metabolized by the soluble epoxide hydrolase (sEH) and potent inhibitors of this enzyme are currently available, pharmacological sEH inhibition seems to be a feasible approach to elevate EET level in vivo. Hence, first clinical trials on sEH inhibition in man have begun. This review focuses on sEH inhibition as a novel pharmacological cardiovascular protective strategy with special regard to in vivo investigations.

    Abstract The miombo region in Africa is covered by a mosaic of woodlands and geoxylic grasslands and is subject to disturbances such as fires, frost and drought, and low nutrient availability. The dominance of Fabaceae Detarioideae species in miombo ecosystems is remarkable but little understood. We therefore compared plant functional traits (PFTs) of common woody species of the Angolan plateau, grouped by life form (trees, geoxyles), lineage (Fabaceae: Detarioideae, non-Detarioideae) and symbiont association (ectomycorrhiza, rhizobia). PFTs reflect group-specific adaptations to prevalent environmental conditions. To analyse the impact of environmental drivers, we selected PFTs reflecting ecophysiological aspects of leaf morphology, nutrient content and water transport. Traits were measured following standardized protocols. We found differences in key PFTs between trees and geoxyles reflecting both life form-specific adaptations to environmental conditions and lineage-specific strategies to cope with environmental stresses. We interpret higher leaf thickness and higher wood density of geoxyles as responses to harsher open environments. Fabaceae in general and ectomycorrhizal species showed better nutrient status. Symbiotic associations of detarioid legumes with ectomycorrhiza show specific advantages for phosphorous uptake as compared to Rhizobia-associated Fabaceae and to non-Fabaceae and thus may be crucial for the stunning dominance of Detarioideae in miombo landscapes.

    Abstract Background: Right heart failure is a fatal consequence of chronic pulmonary hypertension (PH). The development of PH is characterized by increased proliferation of vascular cells, in particular pulmonary artery smooth muscle cells (PASMCs) and pulmonary artery endothelial cells. In the course of PH, an escalated right ventricular (RV) afterload occurs, which leads to increased perioperative morbidity and mortality. BK(Ca) channels are ubiquitously expressed in vascular smooth muscle cells and their opening induces cell membrane hyperpolarization followed by vasodilation. Moreover, BK activation induces anti-proliferative effects in a multitude of cell types. On this basis, we hypothesized that treatment with the nebulized BK channel opener NS1619 might be a therapy option for pulmonary hypertension and tested this in rats.
    Methods: (1) Rats received monocrotaline injection for PH induction. Twenty-four days later, rats were anesthetized and NS1619 or the solvent was administered by inhalation. Systemic hemodynamic parameters, RV hemodynamic parameters, and blood gas analyses were measured before as well as 30 and 120 minutes after inhalation. (2) Rat PASMCs were stimulated with PDGF-BB in the presence and absence of NS1619. AKT, ERK1 and ERK2 activation were investigated by western blot analyses, and relative cell number was determined 48 hours after stimulation.
    Results: Inhalation of a 12 µM and 100 µM NS1619 solution significantly reduced RV pressure without affecting systemic arterial pressure. Blood gas analyses demonstrated significantly reduced carbon dioxide and improved oxygenation in NS1619-treated animals pointing towards a considerable pulmonary shunt-reducing effect. In PASMC's, NS1619 (100 µM) significantly attenuated PASMC proliferation by a pathway independent of AKT and ERK1/2 activation.
    Conclusion: NS1619 inhalation reduces RV pressure and improves oxygen supply and its application inhibits PASMC proliferation in vitro. Hence, BK opening might be a novel option for the treatment of pulmonary hypertension.

    Abstract Formation of abdominal aortic aneurysms is a progressive inflammatory process that involves infiltration and differentiation of monocytes in the vessel wall, proliferation and migration of smooth muscle cells, and eventually the degradation of the internal elastic lamina, which leads to outward vascular remodeling and distension of the vessel. Because calcium channel blockers exert multiple beneficial effects on the vascular system, we investigated the effect of the benzothiazepine-type calcium channel blocker diltiazem on aneurysm formation in a mouse model. Angiotensin II infusion induced massive suprarenal aortic aneurysm formation in male apolipoprotein E-deficient mice that was blocked by cotreatment with diltiazem even if the blood pressure was controlled by coinfusion of phenylephrine. Diltiazem prevented the angiotensin II-mediated induction of proinflammatory cytokines after 7 days of angiotensin II treatment in the aortic arch attributable to a reduction in the amount of locally infiltrating macrophages. To identify the underlying mechanism, vascular segments and cultured vascular cells as well as monocytes were studied. Diltiazem failed to reduce the angiotensin II-induced expression of proinflammatory chemokines and cytokines in isolated mouse thoracic aortic segments in organ culture. Furthermore, diltiazem did not affect the recruitment of proinflammatory Ly6C(+) monocytes in vivo pointing toward an effect of the compound on gene expression in monocytes/macrophages. Indeed, diltiazem prevented the interleukin-6-induced mRNA expression of interleukin-1β and the monocyte chemoattractant protein CCL12 in peritoneal macrophages and RAW264.7 cells independent of the intracellular calcium concentration. Thus, diltiazem limits aortic aneurysm formation in mice by a blood pressure-independent anti-inflammatory effect on monocytic cells.

    Abstract The suprachiasmatic nucleus (SCN) contains the primary mammalian circadian clock. This clock is entrained to environmental rhythms by external stimuli called zeitgebers. This entrainment is accomplished by the activation of specific, interacting signal transduction cascades. Since a cyclic guanosine monophosphate-dependent mechanism play a crucial functional role for light entrainment in the late night and for transmission of cholinergic stimuli, we examined the expression of protein kinase (PKG) in the rat SCN by means of qualitative and semi-quantitative immunocytochemistry. Immunoreaction (IR) for the isozyme protein kinase G I (PKG I) was found in the dorsomedial part of the SCN considered as an important relay in the output pathways of the clock. Within the SCN, PKG-I IR was colocalized with arginine-vasopressin-IR. The intensities of the PKG-I-IR did not vary between day and night.
