Periconceptional intake of folic acid among low-risk women in Canada: summary of a workshop aiming to align prenatal folic acid supplement composition with current expert guidelines.

Am J Clin Nutr 2018 Dec;108(6):1357-1368

School of Nutrition Sciences, University of Ottawa, Ottawa, Ontario, Canada.

The Government of Canada and the Society of Obstetricians and Gynaecologists of Canada both recommend a daily multivitamin supplement containing 400 µg folic acid (FA) for the primary prevention of neural tube defects among low-risk women from before conception and throughout lactation. Prenatal supplements marketed and prescribed in Canada typically exceed the recommended dose, usually providing ≥1000 µg FA/d. This high daily dose, coupled with staple-food FA fortification, has resulted in the observation of very high blood folate concentrations among reproductive-aged women consuming FA-containing supplements.

Haemodynamic stress-induced breaches of the arterial intima trigger inflammation and drive atherogenesis.

Eur Heart J 2018 Dec 11. Epub 2018 Dec 11.

INSERM U1148, Laboratory for Vascular Translational Science (LVTS), DHU FIRE, University Paris Diderot, Sorbonne Paris Cité, 46 rue Henri Huchard, Paris, France.

Aims: Inflammatory mediators, including blood cells and their products, contribute critically to atherogenesis, but the igniting triggers of inflammation remain elusive. Atherosclerosis develops at sites of flow perturbation, where the enhanced haemodynamic stress could initiate the atherogenic inflammatory process due to the occurrence of mechanic injury. We investigated the role of haemodynamic stress-induced breaches, allowing the entry of blood cells in the arterial intima, in triggering inflammation-driven atherogenesis. Read More

Comparison of Candesartan and Angiotensin-(1-7) Combination and Mito Tempo Treatment for Normalizing Blood Pressure and Sympathovagal Balance in (Mren2)27 Rats.

J Cardiovasc Pharmacol 2018 Dec 10. Epub 2018 Dec 10.

Hypertension & Vascular Research, Cardiovascular Sciences Center, Wake Forest University School of Medicine, Medical Center Boulevard, Winston-Salem, NC 27157.

Hypertensive transgenic (mRen2)27 rats exhibit impaired baroreflex sensitivity (BRS) for control of heart rate (HR). Intracerebroventricular (ICV) infusion of Ang-(1-7) improves indices of vagal BRS independent of lowering mean arterial pressure (MAP), while AT1 receptor blockade normalizes MAP and indices of sympathetic tone without correcting the vagal BRS. Scavenging cellular reactive oxygen species (ROS) with tempol in brain fails to correct either hypertension or sympathovagal balance in these animals, despite reports that mitochondrial ROS contributes to Ang II-infusion hypertension.

J Hypertens 2018 Dec 11. Epub 2018 Dec 11.

Boehringer Ingelheim International GmbH, Ingelheim.

Objective: Concomitant treatment with angiotensin-converting enzyme (ACE) inhibitors and dipeptidyl peptidase-4 (DPP-4) inhibitors is increasingly common. Pharmacological studies have suggested a potential adverse drug interaction between ACE inhibitors and DPP-4 inhibitors resulting in unfavorable hemodynamic changes; very few studies have examined such an interaction between angiotensin II receptor blockers (ARBs) and DPP-4 inhibitors. We investigated blood pressure (BP) and heart rate (HR) during treatment with the DPP-4 inhibitor linagliptin in individuals receiving either ACE inhibitors or ARBs in the MARLINA-T2D trial.

Neutrophils in lupus nephritis.

Curr Opin Rheumatol 2018 Dec 11. Epub 2018 Dec 11.

Center for Excellence in Vascular Biology, Department of Pathology, Brigham and Women's Hospital & Harvard Medical School, Boston, USA.

Purpose Of Review: Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease characterized by IgG-autoantibodies to nuclear antigens that can deposit in the kidney and trigger lupus nephritis. Neutrophils accumulate in the kidneys of patients with proliferative LUPUS NEPHRITIS and neutrophil products and a subset of granulocytes, called low-density granulocytes (LDG) may contribute to lupus nephritis pathogenesis. Here, we will discuss recent studies implicating neutrophils in the pathogenesis of human SLE nephritis and then examine studies that provide mechanistic insights into how these cells are recruited to the glomerulus following immune complex deposition and how their products may promote lupus nephritis.

Identification of molecular signatures of cystic fibrosis disease status using plasma-based functional genomics

Physiol Genomics 2018 12 12. Epub 2018 Dec 12.

Department of Pediatrics, Medical College of Wisconsin, United States.

Although cystic fibrosis (CF) is attributed to dysfunction of a single gene, the relationships between the abnormal gene product and development of inflammation and progression of lung disease are not fully understood, limiting our ability to predict an individual patient's clinical course and treatment response. To better understand CF progression, we characterized the molecular signatures of CF disease status using plasma-based functional genomics. Peripheral blood mononuclear cells (PBMCs) from healthy donors were cultured with plasma samples from CF patients (n=103) and unrelated, healthy controls (n=31). Read More

Cdc42 negatively regulates endocytosis during apical membrane maintenance in live animals.

Mol Biol Cell 2018 Dec 12:mbcE18100615. Epub 2018 Dec 12.

Laboratory of Cellular and Molecular Biology, Center for Cancer Research, National Cancer Institute, National Institutes of Health, 37 Convent Dr. Rm 2050B, Bethesda, MD, 20892 USA.

Lumen establishment and maintenance are fundamental for tubular organs physiological functions. Most of the studies investigating the mechanisms regulating this process have been carried out in cell cultures or in smaller organisms, whereas little has been done in mammalian model systems in vivo. Here we used the salivary glands of live mice to examine the role of the small GTPase Cdc42 in the regulation of the homeostasis of the intercellular canaliculi, a specialized apical domain of the acinar cells, where protein and fluid secretion occur.
