A novel therapeutic approach for treating resistant hypertension could be the use of bioelectronic medicines to achieve blood pressure (BP) control in implanted patients by closed-loop stimulation of the left vagus nerve (LVN). However, such a technology would require an implantable BP marker, which is not available yet. As it is known that the LVN conducts afferent BP-related signals, this study aimed to investigate if such signals could be recorded with implantable means and used to derive BP markers. The present experiments were performed in anesthetized pigs subjected to a transient or stable BP increase induced by adrenaline administration...

A tight interaction between endocrine and immune systems takes place mainly due to the key role of head kidney in both hormone and cytokine secretion, particularly under stress situations in which the physiological response promotes the synthesis and release of stress hormones which may lead into immunomodulation as side effect. Although such interaction has been previously investigated, this study evaluated for the first time the effect of stress-associated hormones together with their receptor antagonists on the expression of cytokine genes in head kidney primary cell culture (HKPCC) of the freshwater rainbow trout (Oncorhynchus mykiss) and the seawater gilthead sea bream (Sparus aurata)...

Octopamine, the invertebrate counterpart of adrenaline and noradrenaline, controls and modulates many physiological and behavioral processes in protostomes. It mediates its effects by binding to specific receptors belonging to the superfamily of G-protein coupled receptors. We report the cloning of a cDNA from the brown planthopper (Nloa2b2) sharing high similarity with members of the OA2B2 receptor class. Activation of NlOA2B2 by octopamine increased the production of cAMP in a dose-dependent manner (EC50 = 114 nM)...

Data regarding the effects of selective serotonin reuptake inhibitors (SSRIs), which are a common type of antidepressants, on cardiovascular autonomic function are inconsistent. The present study was conducted to determine the effects of chronic fluoxetine, an SSRI, on blood pressure, cardiac autonomic nervous activities and baroreflex control of heart rate. Male Sprague-Dawley rats were treated with fluoxetine (10mg/kg day, p.o.) or saline for 14 weeks. Baroreflex function was determined by the sigmoid logistic method based on the heart rate responses to changes in blood pressure elicited by phenylephrine or sodium nitroprusside infusions...

Lysobacter are a group of environmental bacteria that are emerging as a new source of antibiotics. One characteristic of Lysobacter is intrinsic resistance to multiple antibiotics, which had not been studied. To understand the resistant mechanism, we tested the effect of blocking two-component regulator systems (TCS) on antibiotic resistance of L. enzymogenes, a prolific producer of antibiotics. Upon treatment with LED209, an inhibitor of the widespread TCS QseC/QseB, L. enzymogenes produced a large amount of an unknown metabolite that was barely detectable in the untreated culture...

Altered concentrations of monoamine neurotransmitters and metabolites have been repeatedly found in people with Down syndrome (DS, trisomy 21). Because of the limited availability of human post-mortem tissue, DS mouse models are of great interest to study these changes and the underlying neurobiological mechanisms. Although previous studies have shown the potential of Ts65Dn mice - the most widely used mouse model of DS - to model noradrenergic changes, a comprehensive monoaminergic characterization in multiple brain regions has not been performed so far...

Split-thickness skin grafting (STSG) is the most common reconstructive procedure in managing burn injuries. Harvesting split-thickness skin creates a new partial thickness wound referred to as the donor site. Pain at the donor site is reported to be one of the most distressing symptoms during the early post-operative period. Here, we a) identify strategies for managing donor site pain, b) assess the quality of individual studies and c) formulate evidence-based recommendations based on the amount and consistency of evidence...

Adrenaline changes expression of the genes encoding peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC-1α), which is known as a regulator of muscle size, and atrogin-1/muscle atrophy F-box (MAFbx), which is a muscle-specific ubiquitin ligase. However, the subtype of β-adrenergic receptor (β-AR) involved in regulating these genes in skeletal muscle is not yet well defined. In this study, the effects of intraperitoneal injection of adrenaline and three β1-3-AR selective agonists on chick skeletal muscle metabolism were examined, to evaluate the functions of β-AR subtypes...
