Use of and intentions to use dermoscopy among physicians in the United States.

Dermatology practical & conceptual

Morris JB, Alfonso SV, Hernandez N, Fernández MI.
PMID: 28515986
Dermatol Pract Concept. 2017 Apr 30;7(2):7-16. doi: 10.5826/dpc.0702a02. eCollection 2017 Apr.

BACKGROUND: Dermatologists routinely use dermoscopy to improve diagnostic accuracy of skin cancers. Much less is known about its use among other physicians who routinely examine the skin, such as family physicians, internists and plastic surgeons.OBJECTIVES: To document the use...

Vertigo and Dizziness in the Elderly.

Frontiers in neurology

Fernández L, Breinbauer HA, Delano PH.
PMID: 26167157
Front Neurol. 2015 Jun 26;6:144. doi: 10.3389/fneur.2015.00144. eCollection 2015.

The prevalence of vertigo and dizziness in people aged more than 60 years reaches 30%, and due to aging of world population, the number of patients is rapidly increasing. The presence of dizziness in the elderly is a strong...

Coexistence of competing metabolic pathways in well-mixed populations.

Physical review. E

Fernández L, Amado A, Campos PR, Ferreira FF.
PMID: 27300918
Phys Rev E. 2016 May;93(5):052401. doi: 10.1103/PhysRevE.93.052401. Epub 2016 May 05.

Understanding why strains with different metabolic pathways that compete for a single limiting resource coexist is a challenging issue within a theoretical perspective. Previous investigations rely on mechanisms such as group or spatial structuring to achieve a stable coexistence...

PO-04 - A new genetic risk score for predicting venous thromboembolic events in cancer patients receiving chemotherapy.

Thrombosis research

Martín AJ, Ziyatdinov A, Rubio VC, Olmos VP, Huerta BM, Rodríguez JC, Fernández MS, de Castro EM, Caro RL, Fernández JM.
PMID: 27161691
Thromb Res. 2016 Apr;140:S177-8. doi: 10.1016/S0049-3848(16)30137-2. Epub 2016 Apr 08.

BACKGROUND: Venous thromboembolism (VTE) is one of the major causes of cancer-associated mortality. Risk for developing VTE increases when in chemotherapy, mainly in the outpatient setting. Current risk scores for predicting chemotherapy-associated VTE have low/moderate discrimination capacity. These models...

Electrochemical generation of antimony volatile species, stibine, using gold and silver mercury amalgamated cathodes and determination of Sb by flame atomic absorption spectrometry.

Talanta

Ordoñes J, Fernández L, Romero H, Carrera P, Alvarado J.
PMID: 25966412
Talanta. 2015 Aug 15;141:259-66. doi: 10.1016/j.talanta.2015.04.025. Epub 2015 Apr 16.

The electrochemical generation of antimony volatile species (stibine) using Au and Ag mercury amalgamated cathodes is described. Compared with some other cathode materials commonly used for electrochemical hydride generation, performance of the amalgamated cathodes is substantially better in the...

Self-assembly of Janus particles into helices with tunable pitch.

Physical review. E, Statistical, nonlinear, and soft matter physics

Fernández MS, Misko VR, Peeters FM.
PMID: 26565242
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Oct;92(4):042309. doi: 10.1103/PhysRevE.92.042309. Epub 2015 Oct 15.

Janus particles present an important class of building blocks for directional assembly. These are compartmentalized colloids with two different hemispheres. In this work we consider a three-dimensional model of Janus spheres that contain one hydrophobic and one charged hemisphere....

Wingless-type family member 3A triggers neuronal polarization via cross-activation of the insulin-like growth factor-1 receptor pathway.

Frontiers in cellular neuroscience

Bernis ME, Oksdath M, Dupraz S, Nieto Guil A, Fernández MM, Malchiodi EL, Rosso SB, Quiroga S.
PMID: 24298236
Front Cell Neurosci. 2013 Oct 25;7:194. doi: 10.3389/fncel.2013.00194. eCollection 2013.

Initial axonal elongation is essential for neuronal polarization and requires polarized activation of IGF-1 receptors (IGF-1r) and the phosphatidylinositol 3 kinase (PI3k) pathway. Wingless-type family growth factors (Wnts) have also been implied in the regulation of axonal development. It...

Population genetics structure of glyphosate-resistant Johnsongrass (Sorghum halepense L. Pers) does not support a single origin of the resistance.

Ecology and evolution

Fernández L, de Haro LA, Distefano AJ, Carolina Martínez M, Lía V, Papa JC, Olea I, Tosto D, Esteban Hopp H.
PMID: 24223277
Ecol Evol. 2013 Sep;3(10):3388-400. doi: 10.1002/ece3.671. Epub 2013 Aug 24.

Single sequence repeats (SSR) developed for Sorghum bicolor were used to characterize the genetic distance of 46 different Sorghum halepense (Johnsongrass) accessions from Argentina some of which have evolved toward glyphosate resistance. Since Johnsongrass is an allotetraploid and only...

Effects of policosanol on borderline to mildly elevated serum total cholesterol levels: a prospective, double-blind, placebo-controlled, parallel-group, comparative study.

Current therapeutic research, clinical and experimental

Castaño G, Más R, Fernández J, López E, Illnait J, Fernández L, Mesa M.
PMID: 24944402
Curr Ther Res Clin Exp. 2003 Sep;64(8):522-37. doi: 10.1016/j.curtheres.2003.09.002.

BACKGROUND: Hypercholesterolemia is a major risk factor for coronary heart disease. Clinical studies have shown that lowering elevated serum cholesterol levels, particularly low-density lipoprotein cholesterol (LDL-C), is beneficial for patients with borderline to mildly elevated serum total cholesterol (TC)...
