The effects of oral hydrolytic enzymes and flavonoids on inflammatory markers and coagulation after marathon running: study protocol for a randomized, double-blind, placebo-controlled trial.

BMC sports science, medicine & rehabilitation

Grabs V, Nieman DC, Haller B, Halle M, Scherr J.
PMID: 24559067
BMC Sports Sci Med Rehabil. 2014 Feb 22;6(1):8. doi: 10.1186/2052-1847-6-8.

BACKGROUND: Regular moderate intensity physical activity positively influences the immune system with a lower incidence of upper respiratory tract infections (URTI) and lower levels of pro-inflammatory markers. However, marathon running due to its strenuous and prolonged nature results in...

The potential for transition metal-mediated neurodegeneration in amyotrophic lateral sclerosis.

Frontiers in aging neuroscience

Lovejoy DB, Guillemin GJ.
PMID: 25100994
Front Aging Neurosci. 2014 Jul 23;6:173. doi: 10.3389/fnagi.2014.00173. eCollection 2014.

Modulations of the potentially toxic transition metals iron (Fe) and copper (Cu) are implicated in the neurodegenerative process in a variety of human disease states including amyotrophic lateral sclerosis (ALS). However, the precise role played by these metals is...

The value of online learning and MRI: finding a niche for expensive technologies.

BACKGROUND: The benefits of online learning come at a price. How can we optimize the overall value?AIMS: Critically appraise the value of online learning.METHODS: Narrative review.RESULTS: Several prevalent myths overinflate the value of online learning. These include that online...

Electronic and vibrational circular dichroism spectroscopies for the understanding of chiral organization in porphyrin aggregates.

Chemical communications (Cambridge, England)

Nieto-Ortega B, Ramírez FJ, Amabilino DB, Linares M, Beljonne D, López Navarrete JT, Casado J.
PMID: 22872159
Chem Commun (Camb). 2012 Sep 21;48(73):9147-9. doi: 10.1039/c2cc34374f. Epub 2012 Aug 08.

Dichroic optical spectroscopies and theoretical modelling have been used to describe the structure of aggregates of porphyrins in their gels in terms of: (i) the formation of helicoidal structures, (ii) the sign of the handedness, (iii) their extent and...

Global solutions of restricted open-shell Hartree-Fock theory from semidefinite programming with applications to strongly correlated quantum systems.

The Journal of chemical physics

Veeraraghavan S, Mazziotti DA.
PMID: 24697423
J Chem Phys. 2014 Mar 28;140(12):124106. doi: 10.1063/1.4868242.

We present a density matrix approach for computing global solutions of restricted open-shell Hartree-Fock theory, based on semidefinite programming (SDP), that gives upper and lower bounds on the Hartree-Fock energy of quantum systems. While wave function approaches to Hartree-Fock...

TLR Agonists as Modulators of the Innate Immune Response and Their Potential as Agents Against Infectious Disease.

Frontiers in immunology

Mifsud EJ, Tan AC, Jackson DC.
PMID: 24624130
Front Immunol. 2014 Mar 03;5:79. doi: 10.3389/fimmu.2014.00079. eCollection 2014.

Immunotherapies that can either activate or suppress innate immune responses are being investigated as treatments against infectious diseases and the pathology they can cause. The objective of these therapies is to elicit protective immune responses thereby limiting the harm...

Rifaximin therapy of irritable bowel syndrome.

Clinical medicine insights. Gastroenterology

Koo HL, Sabounchi S, Huang DB, DuPont HL.
PMID: 24833932
Clin Med Insights Gastroenterol. 2012 Jun 25;5:31-41. doi: 10.4137/CGast.S7382. eCollection 2012.

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder characterized by abdominal pain and altered bowel habits in the absence of specific organic pathology. Although the underlying pathogenesis of IBS is not well-understood, small intestinal bacterial overgrowth (SIBO) or...

Daytime intragastric acid control: post hoc analyses of esomeprazole 20 mg and over-the-counter proton-pump inhibitors.

Therapeutic advances in gastroenterology

Katz P, Kahrilas PJ, Johnson DA, Lind T, Röhss K, Traxler B, Hugo V, Dent J.
PMID: 26557888
