Background: Inositols (INOs) supplementation during pregnancy, specifically the combination of myo-inositol (MI) and D-chiro-inositol (DCI), has been reported to improve vascular parameters in women with gestational diabetes mellitus. We demonstrated previously that offspring born to pregnant mice lacking endothelial nitric oxide synthase (eNOS+/-) gene have hypertension (HTN) as adults and when fed high fat diet (HFD) develop a metabolic syndrome (MS) phenotype.
Objective: Our aim was to evaluate if INOs treatment in pregnancy complicated by MS improves the vascular and metabolic profile in mice offspring programmed in utero to develop HTN and MS. Read More

Normal gut function relies on the activity of the enteric nervous system (ENS) found within the wall of the gastrointestinal tract. The structural and functional organisation of the ENS has been extensively studied in the guinea pig small intestine, but less is known about colonic circuitry. Given that there are significant differences between these regions in function, observed motor patterns and pathology, it would be valuable to have a better understanding of the colonic ENS.

Although Berberis plant species have been advocated as immune modulators, information regarding their mechanism(s) of action is limited. Therefore, in the present study we assessed the efficacy of Berberis lycium Royle fruit extract (BLFE) in the attenuation of lipopolysaccharide (LPS)-induced oxi-inflammatory aggravation and concanavalin A (Con-A)-induced proliferation in murine peritoneal macrophages and lymphocytes, respectively. BLFE strongly suppressed production of the oxidative and inflammatory effector molecules nitric oxide (NO), reactive oxygen species (ROS), inducible nitric oxide synthase (iNOS), inflammatory cytokines (TNF-α/IL-6/IL-1β/IFN-γ) as well as chemokines (MCP-1 and RANTES), with a concomitant enhancement in heme oxygenase-1 (HO-1) and IL-10 levels.

Exposure to traffic-related air pollutants has been associated with increased risk of adverse cardiopulmonary outcomes and mortality; however, the biochemical pathways linking exposure to disease are not known. To delineate biological response mechanisms associated with exposure to near-highway ultrafine particles (UFP), we used untargeted high-resolution metabolomics to profile plasma from 59 participants enrolled in the Community Assessment of Freeway Exposure and Health (CAFEH) study. Metabolic variations associated with UFP exposure were assessed using a cross-sectional study design based upon low (mean 16,000 particles/cm) and high (mean 24,000 particles/cm) annual average UFP exposures.

Phytochemical investigation of the EtOAc-soluble fraction of the ethanolic extract of a yellow mutant of the fungus Monascus purpureus BCRC 38110 (Eurotiaceae) grown on rice resulted in the isolation of one new azaphilone derivative, monapurpureusone (1), one acetophenone metabolite isolated for the first time from natural source, monapurpureusin (2), along with four known compounds, TW94a (3), ergosterol (4), monascin (5), and ankaflavin (6). The structures and relative configurations of these compounds were elucidated by spectroscopic analyses, including 1D- and 2D-NMR spectroscopy and mass spectrometry, and by the comparison of their NMR data with those of related compounds. Some phytochemicals were evaluated for both anti-inflammatory activity through the measurement of nitric oxide (NO) production levels in lipopolysaccharide (LPS)-stimulated murine-derived macrophages RAW264.

Age-associated frailty is predominantly due to loss of muscle mass and function. The loss of muscle mass is also associated with a greater loss of muscle strength, suggesting that the remaining muscle fibres are weaker than those of adults. The mechanisms by which muscle is lost with age are unclear, but in this review we aim to pull together various strands of evidence to explain how muscle contractions support proteostasis in non-muscle tissues, particularly focussed on the production and potential transfer of Heat Shock Proteins (HSPs) and how this may fail during ageing, Furthermore we will identify logical approaches, based on this hypothesis, by which muscle loss in ageing may be reduced.

Ionizing radiation (IR) leads to a variety of the cardiovascular diseases, including the arterial hypertension. A number of studies have demonstrated that blood vessels represent important target for IR, and the endothelium is one of the most vulnerable components of the vascular wall. IR causes an inhibition of nitric oxide (NO)-mediated endothelium-dependent vasodilatation and generation of reactive oxygen (ROS) and nitrogen (RNS) species trigger this process. Read More

Key Points: It is unknown whether excessive reactive oxygen species (ROS) production drives the isocapnic hyperoxia (IH)-induced decline in human cerebral blood flow (CBF) via reduced nitric oxide (NO) bioavailability and leads to disruption of the blood-brain barrier (BBB) or neural-parenchymal damage. We then simultaneously quantified CBF, metabolic rate for oxygen (CMRO ) and transcerebral exchanges of NO-end products, oxidant, antioxidant, and neural-parenchymal damage markers under IH with intravenous saline and vitamin C infusion. CBF and CMRO were reduced during IH, responses that were followed by increased oxidative stress and reduced NO bioavailability when saline was infused. Read More

Key Points: In humans, the vasodilatory response to skeletal muscle contraction is mediated in part by activation of inwardly rectifying potassium (K ) channels. Evidence from animal models suggest that K channels serve as electrical amplifiers of endothelium-dependent hyperpolarization (EDH). We found that skeletal muscle contraction amplifies vasodilatation to the endothelium-dependent agonist acetylcholine (ACh), whereas there was no change in the vasodilatory response to sodium nitroprusside, an endothelium-independent nitric oxide donor.

Endothelial cells (ECs) are the innermost layer of blood vessels that play important roles in homeostasis and vascular function. However, recent evidence suggests that the onset of inflammation and the production of reactive oxygen species impair the function of ECs and are a main factor in the development of cardiovascular disease (CVD). In this study, we investigated the effects of inflammatory markers, oxidative stress, and treatment on ECs in CVD patients. Read More

Bitter (T2R) and sweet (T1R) taste receptors have been implicated in sinonasal innate immunity and in the pathophysiology of chronic rhinosinusitis (CRS). Taste receptors are expressed on several sinonasal cell types including ciliated epithelial cells and solitary chemosensory cells. Bitter agonists released by pathogenic microbes elicit a T2R dependent signaling cascade which induces the release of bactericidal nitric oxide, increases mucociliary clearance, and promotes secretion of antimicrobial peptides.
