PMID: 27214352
Analyst. 2016 Jul 04;141(14):4410-6. doi: 10.1039/c6an00247a.

A new methodology to estimate firing distance based on the direct analysis of organic components of gunshot residues (GSRs) on the bullet impact surface using Fourier transform near-infrared (FT-NIR) spectroscopy is proposed. Mathematical models relating firing distance with spectral...

Carbon nanotubes are promising building blocks for various nanoelectronic components. A highly desirable geometry for such applications is a coil. However, coiled nanotube structures reported so far were inherently defective or had no free ends accessible for contacting. Here...

Computed tomography correlates with cardiopulmonary hemodynamics in pulmonary hypertension in adults with sickle cell disease.

Pulmonary circulation

Linguraru MG, Pura JA, Gladwin MT, Koroulakis AI, Minniti C, Machado RF, Kato GJ, Wood BJ.
PMID: 25006451
Pulm Circ. 2014 Jun;4(2):319-29. doi: 10.1086/675997.

Our objective was to determine whether computed tomography angiography (CTA) measurements of pulmonary artery size can noninvasively assess hemodynamics and diagnose pulmonary hypertension (PH) secondary to sickle cell disease (SCD). Twenty SCD patients with confirmed PH were compared with...

Fibonacci zone plates are proving to be promising candidates in image forming devices. In this letter we show that the set of Fibonacci zone plates are a particular member of a new family of diffractive lenses which can be...

Heterochromatin compaction is regulated by Suv4-20h1 to maintains skeletal muscle stem cells quiescence.

Stem cell investigation

Machado L, Relaix F.
PMID: 27488816
Stem Cell Investig. 2016 Jun 20;3:23. doi: 10.21037/sci.2016.06.04. eCollection 2016.

In this report, Boonsanay and colleagues describe a novel mechanism of maintenance of skeletal muscle stem cells [also known as satellite cells (SCs)] quiescence via the di-methyltransferase Suv4-20h1, regulator of heterochromatin formation. Conditional ablation of Suv4-20h1 in SCs leads...
