This article reconsiders the way that the British state extended its control of the home during the Second World War, using the implementation of air raid precautions and the blackout as a lens through which to view the state's developing attitudes to domestic space. Presented here is not the familiar story of pitch-dark, dangerous streets or altered cityscapes of fear and destruction; instead, by examining personal testimony the article inverts traditional treatments of the blackout to look at the interior of dwellings, demonstrating how the realities of total warfare impinged upon the psychological elements that constituted the home...

This article investigates controversies surrounding dog walking and dog fouling in 1970s and early 1980s Britain, focusing on the microhistory of a series of events in a Lancashire mill town that became known as the 'Burnley Dog War.' A ban on dog walkers from Burnley's main public parks triggered a highly publicised seven-year struggle over access. On one level, the park ban served as a rallying cry for dog lovers across Britain, widening the dividing line between dog owners and dog haters. On another level, it constituted a struggle between antagonists over questions of belonging and exclusion in a town devastated by large-scale deindustrialisation...

Formyl peptide receptor-2 (FPR2) is a G protein-coupled receptor belonging to the N-formyl peptide receptor (FPR) family that plays critical roles in peripheral and brain inflammatory responses. FPR2 has been proposed as a target for the development of drugs that could facilitate the resolution of chronic inflammatory reactions by enhancing endogenous anti-inflammation systems. Starting from the structure of the FPR2 agonists (R)- and (S)-4 and 2, we designed a new series of ureidopropanamide derivatives with the goal of converting functional activity from agonism to antagonism and to develop new FPR2 antagonists...

The development of novel therapeutics to prevent cognitive decline of Alzheimer's disease (AD) is facing paramount difficulties since the translational efficacy of rodent models did not resulted in better clinical results. Currently approved treatments, including the acetylcholinesterase inhibitor donepezil (DON) and the N-methyl-D-aspartate antagonist memantine (MEM) provide marginal therapeutic benefits to AD patients. There is an urgent need to develop a predictive animal model that is phylogenetically proximal to humans to achieve better translation...

BACKGROUND: Esmolol may attenuate the sympathetic response to pain and reduce postoperative opioid consumption. It is not clear whether esmolol has an analgesic effect per se. OBJECTIVES: The aim of this study was to evaluate the analgesic effect of esmolol in the absence of anaesthetics and opioids. We tested the hypothesis that esmolol would reduce the maximum pain intensity perceived during the cold pressor test (CPT) by 2 points on a 0 to 10 numeric pain rating scale (NRS) compared to placebo...

The physiological and behavioural effects of empathy for other's pain have been widely investigated, while the opposite situation, i.e. the influence on one's pain of empathetic feedback from others, remains largely unexplored. Here, we assessed whether and how empathetic and unempathetic comments from observers modulate pain and associated vegetative reactions. In Study 1, conversations between observers of a pain study were recorded by professional actors. Comments were prepared to be perceived as empathetic, unempathetic, or neutral, and were validated in 40 subjects...

The primary motor cortex (M1) presents a somatotopic organization of body parts, but with overlap between muscle/movement representations. This distinct but overlapping M1 organization is believed to be important for individuated control and movement coordination, respectively. Discrete peaks of greater excitability observed within M1 might underpin organization of cortical motor control. This study aimed to examine interactions between M1 representations of synergist and antagonist forearm muscles, compare regions of greater excitability during different functional tasks, and compare characteristics of M1 representation recorded using surface and fine-wire (fw ) electrodes...

Neuroinflammation precedes neuronal loss in striatal neurodegenerative diseases and can be exacerbated by the release of proinflammatory molecules by microglia. These molecules can affect trafficking of AMPARs. The preferential trafficking of calcium-permeable versus impermeable AMPARs can result in disruptions of [Ca(2+) ]i and alter cellular functions. In striatal neurodegenerative diseases, changes in [Ca(2+) ]i and L-type voltage-gated calcium channels (VGCCs) have been reported. Therefore, the present study sought to determine whether a proinflammatory environment alters AMPA-stimulated [Ca(2+) ]i through calcium-permeable AMPARs and/or L-type VGCCs in dopamine-2 and dopamine-1 expressing striatal spiny projection neurons (D2 and D1 SPNs) in the dorsal striatum...

P2Y receptors are G-protein-coupled receptors (GPCRs) for extracellular nucleotides. The platelet ADP-receptor which has been denominated P2Y12 receptor is an important target in pharmacotherapy. The receptor couples to Gαi2 mediating an inhibition of cyclic AMP accumulation and additional downstream events including the activation of phosphatidylinositol-3-kinase and Rap1b proteins. The nucleoside analogue ticagrelor and active metabolites of the thienopyridine compounds ticlopidine, clopidogrel and prasugrel block P2Y12 receptors and, thereby, inhibit ADP-induced platelet aggregation...

Endocannabinoid pharmacology is now relatively well understood with a number of endocannabinoids and endogenous cannabinoid neurotransmitters identified and the pharmacokinetics relatively well ascertained. Further, the cannabinoid receptors are now molecularly and pharmacologically characterised and the cell processes involved in endocannabinoid transcription, synthesis, post-translational modification and protein expression are reported. Endogenous cannabinoids have been shown to have key roles in immune and pain pathways and neuro-behavioural signalling including appetite regulation...

PURPOSE OF REVIEW: The purpose of this review is to discuss the prevention of venous thromboembolism (VTE) in stroke patients. We discuss use of oral anticoagulation and other interventions for the prevention of VTE. A new class of medications, non-vitamin K antagonist oral anticoagulants (NOACs), have been successfully trialed for the prevention of VTE. We review the data and guidance statements for VTE prevention. RECENT FINDINGS: Warfarin and vitamin K antagonist drugs have been the mainstay of VTE prevention for decades...

Mineralocorticoid receptor antagonists (MRAs) constitute a beneficial therapy in chronic heart failure, but their use in the acute heart failure (AHF) setting remains rather unexplored. To assess the effect of MRAs administered during hospitalization on in-hospital outcomes of patients with AHF, we performed a post-hoc analysis of the Acute Heart Failure Global Registry of Standard Treatment (ALARM-HF). Patients of the original study cohort (n = 4953) were categorized according to in-hospital MRA treatment status as MRA-treated (n = 1439) and untreated (n = 3514) subjects...

Transcription factors active in embryonic parathyroid cells can be maintained in adult parathyroids and be involved in tumorigenesis. TBX1, the candidate gene of 22q11.2-DiGeorge syndrome, which includes congenital hypoparathyroidism, is involved in parathyroid embryogenesis. The study aimed to investigate expression, function, and regulation of the parathyroid embryonic transcription factor TBX1 in human parathyroid adult normal and tumor tissues. TBX1 transcripts were detected in normal parathyroids and were deregulated in parathyroid tumors...

OBJECTIVE: Enhanced activation of cell specific mineralocorticoid receptors (MRs) in obesity plays a key role in the development of cardiovascular disease including cardiac diastolic dysfunction as a critical prognosticator. Our previous investigations demonstrated that selective endothelium MR activation promotes a maladaptive inflammatory response and fibrosis in cardiovascular tissue in female mice fed a western diet (WD), and this was associated with expression and activation of the epithelial sodium channel on the surface of endothelial cells (EnNaC)...

Antifungal metabolites produced by Bacillus sp. W10, which was previously isolated from the tomato rhizosphere, were investigated. Strain W10 was identified as Bacillus amyloliquefaciens by analysis of its 16S rDNA and gyrB gene partial sequences. PCR analysis showed the presence of fenB, sfp, and ituD genes, coding for fengycin, surfactin, and iturin, respectively. A novel small antifungal peptide, designated 5240, produced by this strain was isolated by ammonium sulfate precipitation and Superdex 200 gel filtration chromatography...

Studies on serotonin-selective reuptake inhibitors have established that disturbances in the ascending 5-HT neuron systems and their 5-HT receptor subtypes and collateral networks to the forebrain contribute to the etiology of major depression and are targets for treatment. The therapeutic action of serotonin-selective reuptake inhibitors is of proven effectiveness, but the mechanisms underlying their effect are still unclear. There are many 5-HT subtypes involved; some need to be blocked (e.g., 5-HT2A, 5-HT3, and 5-HT7), whereas others need to be activated (e...

Reprogramming of immunosuppressive tumor microenvironment (TME) by targeting alternatively activated tumor associated macrophages (M2TAM), myeloid-derived suppressor cells (MDSC), and regulatory T cells (Tregs), represents a promising strategy for developing novel cancer immunotherapy. Prostaglandin E2 (PGE2), an arachidonic acid pathway metabolite and mediator of chronic inflammation, has emerged as a powerful immunosuppressor in the TME through engagement with one or more of its 4 receptors (EP1-EP4). We have developed E7046, an orally bioavailable EP4-specific antagonist and show here that E7046 has specific and potent inhibitory activity on PGE2-mediated pro-tumor myeloid cell differentiation and activation...

Cholecystokinin (CCK) is an archetypal incretin hormone secreted by intestinal enteroendocrine cells (EEC) in response to ingested nutrients. The aim of this study was to determine whether CCK modulates enterocyte fatty acid uptake by primary mouse duodenal cells. Exposure of primary mouse duodenal cells to 10 pM sulfated CCK-8 caused a two fold increase in dodecanoic acid fatty acid (FA) uptake. The selective CCK A receptor antagonist loxiglumide (100 μM) completely abolished the CCK-8 induced FA uptake. The CD36 fatty acid translocase-specific inhibitor sulfo-N-succinimidyl oleate (1 μM) also completely inhibited CCK-8 induced FA uptake, as did treatment with 200 μM phloretin...
