Understanding the electromagnetic interaction of metal organic framework reactants in aqueous solution at microwave frequencies.

Physical chemistry chemical physics : PCCP

Laybourn A, Katrib J, Palade PA, Easun TL, Champness NR, Schröder M, Kingman SW.
PMID: 26822947
Phys Chem Chem Phys. 2016 Feb 21;18(7):5419-31. doi: 10.1039/c5cp05426e.

Preparation of metal organic frameworks (MOFs) via microwave heating is becoming increasingly popular due to reduced reaction times and enhanced control of MOF particle size. However, there is little understanding about the detailed interaction of the electric field portion...

Estimates of Sulfate Deposition in the Middle Eastern United States: 1975, 1990, and 2010.

Journal of the Air & Waste Management Association (1995)

Norris WB, Mueller SF, Langstaff JE.
PMID: 26355371
J Air Waste Manag Assoc. 1999 Jun;49(6):655-68. doi: 10.1080/10473289.1999.10463839.

Deposition of airborne sulfates and nitrates is considered to be an important factor in the decline of certain fish populations and of forest health in the eastern United States. A solution has been sought through legislation that mandates significant...

Agriculture causes nitrate fertilization of remote alpine lakes.

Nature communications

Hundey EJ, Russell SD, Longstaffe FJ, Moser KA.
PMID: 26853267
Nat Commun. 2016 Feb 08;7:10571. doi: 10.1038/ncomms10571.

Humans have altered Earth's nitrogen cycle so dramatically that reactive nitrogen (Nr) has doubled. This has increased Nr in aquatic ecosystems, which can lead to reduced water quality and ecosystem health. Apportioning sources of Nr to specific ecosystems, however,...

Effects of intravenous caffeine on fractional flow reserve measurements in coronary artery disease.

Open heart

Mutha V, Asrar Ul Haq M, Van Gaal WJ.
PMID: 25332801
Open Heart. 2014 Aug 04;1(1):e000060. doi: 10.1136/openhrt-2014-000060. eCollection 2014.

BACKGROUND: Intravenous adenosine is used to minimise the coronary micro-resistance to achieve maximal hyperaemia along with nitrates for optimal fractional flow reserve (FFR) measurements. We hypothesise that caffeine, being a competitive inhibitor of adenosine, would influence adenosine-mediated FFR readings.METHODS:...

Oral Nitrate Reductase Activity Is Not Associated with Development of Non-Alcoholic Fatty Liver Disease (NAFLD) and Non-Alcoholic Steatohepatitis (NASH): A Pilot Study.

Middle East journal of digestive diseases

Barzin G, Merat S, Nokhbeh-Zaeem H, Saniee P, Pedramnia S, Mostashfi Habibabadi A, Nasseri-Moghaddam S.
PMID: 24829701
Middle East J Dig Dis. 2014 Jan;6(1):23-7.

BACKGROUND NAFLD/NASH is a manifestation of metabolic syndrome and is associated with obesity/overweight. Not all obese/overweight individuals develop NASH. Gastro-esophageal reflux disease (GERD) is considered a gastrointestinal manifestation of the metabolic syndrome and is associated with obesity/overweight. Again not...

Effects of agriculture production systems on nitrate and nitrite accumulation on baby-leaf salads.

Food science & nutrition

Aires A, Carvalho R, Rosa EA, Saavedra MJ.
PMID: 24804008
Food Sci Nutr. 2013 Jan;1(1):3-7. doi: 10.1002/fsn3.1. Epub 2013 Jan 08.

Nitrate and nitrite are widespread contaminants of vegetables, fruits, and waters. The levels of these compounds are increased as a result of using organic wastes from chemical industries, domestic wastes, effluents, nitrogenous fertilizers, and herbicides in agriculture. Therefore, determining...

Selected topics related to occupational exposures. Part V. Occupational cardiovascular disease.

Disease-a-month : DM

Leikin JB, Davis A, Klodd DA, Thunder T, Kelafant GA, Paquette DL, Rothe MJ, Rubin R.

Cardiovascular disease is common in the United States. Several occupational exposures, such as carbon disulfide and organic nitrates, are believed to cause occupational cardiovascular disease. In addition some other agents, such as lead and cadmium, may indirectly cause cardiovascular...

Nitrate-Induced Headache in Patients with Stable Angina Pectoris: Beneficial Effect of Starting on a Low Dosage.

BACKGROUND: Nitrates, although important for the management of angina pectoris, cause significant headache in many patients. METHODS: In a randomized, double-blind crossover study, 89 patients with stable angina pectoris were used to compare two different dosage strategies of isosorbide-5-mononitrate...

Dipyrimidine-copper(II) dinitrate complexes showing magnetic interactions.

Acta Crystallogr B. 2001 Jun;57:288-95. doi: 10.1107/s0108768101002737. Epub 2001 Jun 01.

Crystals of Cu(II)(NO(3))(2)(pm)(3) (1), and two crystalline forms of Cu(II)(NO(3))(2)(H(2)O)(2)(pm)(2), (2) and (3), showed ferromagnetic, antiferromagnetic and paramagnetic interactions at extremely low temperatures, respectively. Crystal structure analyses revealed that the complexes were catena-dinitrato[mu-pyrimidine-kappaN(1):kappaN(3)]-(pyrimidine-N(1))copper(II), [Cu(NO(3))(2)(pm)(2)](n), catena-diaquadinitrato[mu-pyrimidine-kappaN(1):kappaN(3)]copper(II), [Cu(NO(3))(2)(H(2)O)(2)(pm)](n), and diaquadinitratodipyrimidinecopper(II), Cu(NO(3))(2)(H(2)O)(2)(pm)(2)...
