Food allergy: recent advances in pathophysiology and treatment.

Allergy, asthma & immunology research

Wang J, Sampson HA.
PMID: 20224666
Allergy Asthma Immunol Res. 2009 Oct;1(1):19-29. doi: 10.4168/aair.2009.1.1.19. Epub 2009 Sep 25.

Food allergies are adverse immune reactions to food proteins that affect up to 6% of children and 3-4% of adults. A wide range of symptoms can occur depending on whether IgE or non-IgE mediated mechanism are involved. Many factors...

PMID: 21828786
Nanotechnology. 2008 Aug 06;19(31):315401. doi: 10.1088/0957-4484/19/31/315401. Epub 2008 Jun 17.

The behavior of soft magnetic films in spring magnets, as a function of the intensity and orientation of an external magnetic field, is described in the framework of spin-polarized non-collinear electronic structure calculations. As experimentally observed, the critical intensity...

Adv Bioinformatics. 2009;809469. doi: 10.1155/2009/809469. Epub 2009 Oct 07.

In flow cytometry, different cell types are usually selected or "gated" by a series of 1- or 2-dimensional geometric subsets of the measurements made on each cell. This is easily accomplished in commercial flow cytometry packages but it is...

Density functional study of the structures and electronic properties of nitrogen-doped Ni(n) clusters, n = 1-10.

We present a first-principles study of the equilibrium geometries, electronic structure, and related properties (binding energies, ionization potentials, electron affinities, and magnetic moments) of free-standing Ni(n) (n = 1-10) clusters doped with one impurity of N. Calculations have been...

Mandibular midline distraction osteogenesis.

Oral health and dental management

Botzenhart UU, Végh A, Jianu R, Gedrange T.
PMID: 24390034
Oral Health Dent Manag. 2013 Dec;12(4):305-12.

In orthodontics, bone structure, its density and dimensions play an essential role by explaining limitations in magnitude, size and extent of tooth movement. Severe anterior crowding is one of the most frequently encountered dental malocclusions. Its therapy is mostly...

Magnetic cooperative effects in small Ni-Ru clusters.

The journal of physical chemistry. A

Aguilera-Granja F, Longo RC, Gallego LJ, Vega A.
PMID: 22029415
J Phys Chem A. 2011 Dec 01;115(47):13950-5. doi: 10.1021/jp208802e. Epub 2011 Nov 09.

We report ab initio calculations of the structures, magnetic moments, and electronic properties of Ni(7)-xRu(x) clusters (x = 0-7) using a density-functional method that employs linear combinations of pseudoatomic orbitals as basis sets, nonlocal norm-conserving pseudopotentials, and the generalized...

Acta crystallographica. Section E, Structure reports online

Pop LC, Preite M, Manriquez JM, Vega A, Chavez I.
PMID: 22606132
Acta Crystallogr Sect E Struct Rep Online. 2012 Apr 01;68:o1192. doi: 10.1107/S1600536812012056. Epub 2012 Mar 28.

The asymmetric unit of the title solvate, C(20)H(14)O(4)·2C(2)D(6)OS, contains half of the substituted terephthalic acid mol-ecule and one solvent mol-ecule. The centroid of the central benzene ring in the acid mol-ecule is coincident with a crystallographic inversion center. Neither...

Open Allergy J. 2011 Dec 09;4:24-34. doi: 10.2174/1874838401104010024.

Previous studies have indicated that specific molecular properties of proteins may determine their allergenicity. Allergen interaction with epithelia as the first contact site could be decisive for a resulting immune response. We investigate here for the major peanut allergen...

An unusual and unique conformation of a paddle wheel type binuclear copper(II) complex containing acetate and acetamido ligands, {Cu2(μ2-O2CCH3)4}(OCNH2CH3) (1), was obtained by solvothermal synthesis. The structural characterization of this compound shows that the apical (acetamido) ligands are disposed...
