The impact of hydroelectric dams on mercury dynamics in South America: A review.

Chemosphere 2018 Dec 6;219:546-556. Epub 2018 Dec 6.

Programa de Pós-Graduação Em Ecologia e Recursos Naturais, Laboratório de Ciências Ambientais, Centro de Biociências e Biotecnologia, Universidade Estadual Do Norte Fluminense Darcy Ribeiro, Av. Alberto Lamego, 2000 - Parque Califórnia, CEP: 28013-602, Campos Dos Goytacazes, Rio de Janeiro, Brazil.

The increase in global demand for electric energy is reflected in plans to construct numerous hydroelectric dams in South America that can cause chronic ecological impacts if not built and managed correctly. One of the main impacts generated by hydropower dams is the accumulation of Hg chemical species in their reservoir compartments and the downstream transport of these contaminants. Hg circulation in these environments has been studied for 27 years and this review brings a synthesis of the dynamics that are now well established, so that future studies can focus on gaps and inconsistent results in the literature.

Immune cells in the retina and choroid: Two different tissue environments that require different defenses and surveillance.

Prog Retin Eye Res 2018 Dec 12. Epub 2018 Dec 12.

Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University, Clayton, Victoria, Australia.

In the eye immune defenses must take place in a plethora of differing microenvironments ranging from the corneal and conjunctival epithelia facing the external environment to the pigmented connective tissue of the uveal tract containing smooth muscle, blood vessels and peripheral nerves to the innermost and highly protected neural retina. The extravascular environment of the neural retina, like the brain parenchyma, is stringently controlled to maintain conditions required for neural transmission. The unique physiological nature of the neural retina can be attributed to the blood retinal barriers (BRB) of the retinal vasculature and the retinal pigment epithelium, which both tightly regulate the transport of small molecules and restrict passage of cells and macromolecules from the circulation into the retina in a similar fashion to the blood brain barrier (BBB).

Acetaminophen cytotoxicity in HepG2 cells is associated with a decoupling of glycolysis from the TCA cycle, loss of NADPH production, and suppression of anabolism.

Arch Toxicol 2018 Dec 14. Epub 2018 Dec 14.

Department of Surgery and Cancer, Faculty of Medicine, Imperial College London, London, UK.

Acetaminophen (APAP) is one of the most commonly used analgesics worldwide, and overdoses are associated with lactic acidosis, hepatocyte toxicity, and acute liver failure due to oxidative stress and mitochondrial dysfunction. Hepatoma cell lines typically lack the CYP450 activity to generate the reactive metabolite of APAP observed in vivo, but are still subject to APAP cytotoxicity. In this study, we employed metabolic profiling and isotope labelling approaches to investigate the metabolic impact of acute exposure to cytotoxic doses of APAP on the widely used HepG2 cell model.

Microneedles: A smart approach and increasing potential for transdermal drug delivery system.

Biomed Pharmacother 2019 Jan 9;109:1249-1258. Epub 2018 Nov 9.

Discipline of Pharmacy, Graduate School of Health, University of Technology Sydney, Ultimo, NSW, 2007, Australia; School of Biomedical Sciences and Pharmacy, The University of Newcastle, Callaghan, NSW, 2308, Australia; Priority Research Centre for Healthy Lungs, Hunter Medical Research Institute, Lot 1 Kookaburra Circuit, New Lambton Heights, Newcastle, NSW 2305, Australia.

The most widely used methods for transdermal administration of the drugs are hypodermic needles, topical creams, and transdermal patches. The effect of most of the therapeutic agents is limited due to the stratum corneum layer of the skin, which serves as a barrier for the molecules and thus only a few molecules are able to reach the site of action. A new form of delivery system called the microneedles helps to enhance the delivery of the drug through this route and overcoming the various problems associated with the conventional formulations.

Geographical adaptation prevails over species-specific determinism in trees' vulnerability to climate change at Mediterranean rear-edge forests.

Glob Chang Biol 2018 Dec 13. Epub 2018 Dec 13.

Ecoclimatology, Department of Ecology and Ecosystem Management, Technische Universität München, Freising, Germany.

Climate change may reduce forest growth and increase forest mortality, which is connected to high carbon costs through reductions in gross primary production and net ecosystem exchange. Yet the spatiotemporal patterns of vulnerability to both short-term extreme events as well as gradual environmental changes are quite uncertain across the species' limits of tolerance to dryness. Such information is fundamental for defining ecologically relevant upper limits of species tolerance to drought and hence, to predict the risk of increased forest mortality and shifts in species composition.

[Effects of glucagon-like peptides on gallbladder motility].

Ugeskr Laeger 2018 Dec;180(50)

As cases of gallbladder-related adverse events have been reported in patients treated with glucagon-like peptide (GLP)-1 receptor agonists and GLP-2 receptor agonists, studies have investigated the effects of these hormones on the enterohepatic circulation of bile acids and gallbladder motility. Results suggest, that bile acids and GLP-2 counteract postprandial cholecystokinin-mediated gallbladder contraction, while GLP-1 may delay gallbladder refilling. This provides important information on the effect and safety of drugs based on GLP-1 and GLP-2, respectively. Read More

Left brachiocephalic vein occlusion in a patient with an aortic arch aneurysm: Rare cause of obstraction for a pacemaker implantation.

J Cardiol Cases 2014 Jan 13;9(1):32-34. Epub 2013 Dec 13.

Department of Cardiology, Tokyo Women's Medical University, Tokyo, Japan.

Venous occlusions or anatomic variants are unexpectedly encountered during transvenous pacing lead implantation procedures. A 78-year-old man, who had been medically treated for a thoracic and abdominal dissecting aortic aneurysm was referred to our hospital for treatment of congestive heart failure due to complete atrioventricular block with bradycardia. At the time of the pacemaker implantation, the guidewire for inserting the introducer sheath could not be advanced into the left brachiocephalic vein. Read More
