Statistical mixture design--principal component optimization for selective compound extraction from plant material.

Journal of separation science

Soares PK, Bruns RE, Scarminio IS.
PMID: 18008278
J Sep Sci. 2007 Dec;30(18):3302-10. doi: 10.1002/jssc.200700236.

A simplex centroid design is used to optimize solvent mixtures for selective extraction of compounds from Erythrina speciosa Andrews leaves. Three main groups of compounds characterized by chromatographic retention times of 1.7, 3.1, and 6.6 min were extracted. The...

Flux-freezing breakdown in high-conductivity magnetohydrodynamic turbulence.

Nature

Eyink G, Vishniac E, Lalescu C, Aluie H, Kanov K, Bürger K, Burns R, Meneveau C, Szalay A.
PMID: 23698445
Nature. 2013 May 23;497(7450):466-9. doi: 10.1038/nature12128.

The idea of 'frozen-in' magnetic field lines for ideal plasmas is useful to explain diverse astrophysical phenomena, for example the shedding of excess angular momentum from protostars by twisting of field lines frozen into the interstellar medium. Frozen-in field...

Statistics on cannabis users skew perceptions of cannabis use.

Frontiers in psychiatry

Burns RM, Caulkins JP, Everingham SS, Kilmer B.
PMID: 24223560
Front Psychiatry. 2013 Nov 06;4:138. doi: 10.3389/fpsyt.2013.00138. eCollection 2013.

UNLABELLED: Collecting information about the prevalence of cannabis use is necessary but not sufficient for understanding the size, dynamics, and outcomes associated with cannabis markets. This paper uses two data sets describing cannabis consumption in the United States and...

Fueling the caries process: carbohydrate metabolism and gene regulation by Streptococcus mutans.

Journal of oral microbiology

Moye ZD, Zeng L, Burne RA.
PMID: 25317251
J Oral Microbiol. 2014 Sep 05;6. doi: 10.3402/jom.v6.24878. eCollection 2014.

The nature of the oral cavity and host behaviors has mandated that the oral microbiota evolve mechanisms for coping with environmental fluctuations, especially changes in the type and availability of carbohydrates. In the case of human dental caries, the...

Health status of returning refugees, internally displaced persons, and the host community in a post-conflict district in northern Sri Lanka: a cross-sectional survey.

Conflict and health

Burns R, Wickramage K, Musah A, Siriwardhana C, Checchi F.
PMID: 30305841
Confl Health. 2018 Oct 01;12:41. doi: 10.1186/s13031-018-0176-7. eCollection 2018.

BACKGROUND: Although the adverse impacts of conflict-driven displacement on health are well-documented, less is known about how health status and associated risk factors differ according to displacement experience. This study quantifies health status and quality of life among returning...

Solvent-Controlled, Site-Selective N-Alkylation Reactions of Azolo-Fused Ring Heterocycles at N1-, N2-, and N3-Positions, Including Pyrazolo[3,4- d]pyrimidines, Purines, [1,2,3]Triazolo[4,5]pyridines, and Related Deaza-Compounds.

The Journal of organic chemistry

Bookser BC, Weinhouse MI, Burns AC, Valiere AN, Valdez LJ, Stanczak P, Na J, Rheingold AL, Moore CE, Dyck B.
PMID: 29790748
J Org Chem. 2018 Jun 15;83(12):6334-6353. doi: 10.1021/acs.joc.8b00540. Epub 2018 Jun 06.

Alkylation of 4-methoxy-1 H-pyrazolo[3,4- d]pyrimidine (1b) with iodomethane in THF using NaHMDS as base selectively provided N2-methyl product 4-methoxy-2-methyl-2 H-pyrazolo[3,4- d]pyrimidine (3b) in an 8/1 ratio over N1-methyl product (2b). Interestingly, conducting the reaction in DMSO reversed selectivity to...

Rotator Cuff Repair Technique With Transosseous Knotless Anchor System.

Arthroscopy techniques

Murphy MM, Tashjian RZ, Burks RT.
PMID: 30258774
Arthrosc Tech. 2018 Aug 20;7(9):e927-e937. doi: 10.1016/j.eats.2018.05.003. eCollection 2018 Sep.

Various surgical techniques exist for rotator cuff repair that provide a suitable environment for tendon-bone healing. Arthroscopic recreation of transosseous repairs, which had previously been performed by open or miniopen techniques, can now be performed; however, arthroscopic, transosseous passage...

DO MALES WITH PATELLOFEMORAL PAIN HAVE POSTEROLATERAL HIP MUSCLE WEAKNESS?.

International journal of sports physical therapy

Hoglund LT, Burns RO, Stepney AL.
PMID: 30090674
Int J Sports Phys Ther. 2018 Apr;13(2):160-170.

BACKGROUND: Patellofemoral pain is common in physically active adults. Females with patellofemoral pain have been shown to have posterolateral hip muscle weakness, but there is a paucity of research examining hip muscle strength in males with patellofemoral pain.HYPOTHESIS/PURPOSE: The...

Kr-PLIF for scalar imaging in supersonic flows.

Optics letters

Narayanaswamy V, Burns R, Clemens NT.

The largest source of experimental error in determining gas phase fundamental infrared intensities arises from the separation of overlapped bands. Quantum chemical calculations at the QCISD/cc-pVTZ and QCISD/aug-cc-pVTZ levels were carried out on four simple hydrocarbons and the fluoro-...
