Origin of spontaneous electric dipoles in homonuclear niobium clusters.

Physical review letters

Andersen KE, Kumar V, Kawazoe Y, Pickett WE.
PMID: 15697833
Phys Rev Lett. 2004 Dec 10;93(24):246105. doi: 10.1103/PhysRevLett.93.246105. Epub 2004 Dec 09.

Surprisingly large, spontaneous electric dipole moments recently observed in homonuclear niobium clusters below 100 K are explained using first-principles electronic structure calculations. The calculated moments for Nb(n) (n < or =15) generally agree with the experimental data. A strong...

Characteristics of dividing and non-dividing Tetrahymena cells at different physiological states.

European journal of protistology

Hellung-Larsen P, Lyhne I, Andersen AP, Koppelhus U.
PMID: 23195541
Eur J Protistol. 1993 May 28;29(2):182-90. doi: 10.1016/S0932-4739(11)80272-5. Epub 2011 Nov 02.

Eight defined physiological states of Tetrahymena pyriformis are described. For dividing cells the states comprise: 1. Exponentially growing cells, 2. Cells at late exponential growth phase, 3. Cells kept at a high cell concentration, 4. Cells shifted up or...

Physical activity and weight management: building the case for exercise.

The Physician and sportsmedicine

Andersen RE, Jakicic JM.
PMID: 20086447
Phys Sportsmed. 2003 Nov;31(11):39-45. doi: 10.3810/psm.2003.11.557.

Exercise interventions are powerful tools for helping many patient populations. For those who need to manage their weight, an exercise program combined with diet modification may be key to losing weight and keeping it off. Many patients who are...

Evidence of carcinogenicity in humans of water-soluble nickel salts.

Journal of occupational medicine and toxicology (London, England)

Grimsrud TK, Andersen A.
PMID: 20377901
J Occup Med Toxicol. 2010 Apr 08;5:7. doi: 10.1186/1745-6673-5-7.

BACKGROUND: Increased risks of nasal cancer and lung cancer in nickel refiners have been investigated scientifically and discussed since they were detected in the 1930s. Nickel compounds are considered to be the main cause of the cancer excess. Parts...

Vitamin D status in female military personnel during combat training.

Journal of the International Society of Sports Nutrition

Andersen NE, Karl JP, Cable SJ, Williams KW, Rood JC, Young AJ, Lieberman HR, McClung JP.
PMID: 21156069
J Int Soc Sports Nutr. 2010 Dec 14;7:38. doi: 10.1186/1550-2783-7-38.

Vitamin D is an essential nutrient for maintaining bone health. Recent data suggest that vitamin D and calcium supplementation might affect stress fracture incidence in military personnel. Although stress fracture is a health risk for military personnel during training,...

PBPK modeling of complex hydrocarbon mixtures: gasoline.

Environmental toxicology and pharmacology

Dennison JE, Andersen ME, Dobrev ID, Mumtaz MM, Yang RS.
PMID: 21782697
Environ Toxicol Pharmacol. 2004 Mar;16(1):107-19. doi: 10.1016/j.etap.2003.10.003.

Petroleum hydrocarbon mixtures such as gasoline, diesel fuel, aviation fuel, and asphalt liquids typically contain hundreds of compounds. These compounds include aliphatic and aromatic hydrocarbons within a specific molecular weight range and sometimes lesser amounts of additives, and often...

Chemical mixture toxicology: from descriptive to mechanistic, and going on to in silico toxicology.

Environmental toxicology and pharmacology

Yang RS, El-Masri HA, Thomas RS, Dobrev ID, Dennison JE, Bae DS, Campain JA, Liao KH, Reisfeld B, Andersen ME, Mumtaz M.
PMID: 21782736
Environ Toxicol Pharmacol. 2004 Nov;18(2):65-81. doi: 10.1016/j.etap.2004.01.015.

Because of the pioneering vision of certain leaders in the biomedical field, the last two decades witnessed rapid advances in the area of chemical mixture toxicology. Earlier studies utilized conventional toxicology protocol and methods, and they were mainly descriptive...

Novel 2-ethyl-5-alkylpyrrolidines in the venom of an australian ant of the genusMonomorium.

Journal of chemical ecology

Jones TH, Blum MS, Andersen AN, Fales HM, Escoubas P.
PMID: 24276992
J Chem Ecol. 1988 Jan;14(1):35-45. doi: 10.1007/BF01022529.

Novel 2-ethyl-5-alkylpyrrolidines and their corresponding 1-pyrrolines have been identified as poison gland products from an unidentified Australian species ofMonomorium. The major alkaloids present in the venom of this ant aretrans-2-ethyl-5-undecylpyrrolidine andtrans-2-ethyl-5-(12-tridecen-1-yl)pyrrolidine. The position of the double bond in the...

Structure of SrTiO3 films on Si.

Physical review letters

Hellberg CS, Andersen KE, Li H, Ryan PJ, Woicik JC.
PMID: 22680736
Phys Rev Lett. 2012 Apr 20;108(16):166101. doi: 10.1103/PhysRevLett.108.166101. Epub 2012 Apr 16.

The epitaxial deposition of oxides on silicon opens the possibility of incorporating their diverse properties into silicon-device technology. Deposition of SrTiO(3) on silicon was first reported over a decade ago, but growing the coherent, lattice-matched films that are critical...
