Hematogônias: distinção com blastos da leucemia linfóide aguda de células B por citometria de fluxo Hematogones: differentiation from B-lineage acute lymphoblastic leukemia by flow cytometry

Revista Brasileira de Hematologia e Hemoterapia, 2006
Hematogônias são precursores normais de linhagem B que apresentam características morfológicas e, algumas vezes, imunológicas similares aos linfoblastos das leucemias linfóides agudas (LLA).

Theory of electromagnon in the multiferroic Mn perovskites: Vital role of higher harmonic components of the spiral spin order

, 2010
We study theoretically the electromagnon and its optical spectrum (OS) of the terahertz-frequency regime in the magnetic-spiral-induced multiferroic phases of the rare-earth (R) Mn perovskites, RMnO3, taking into account the elliptical deformation or the

Hubble Space Telescope Near-Ultraviolet Spectroscopy of the Bright CEMP-no Star BD+44 493

, 2014
We present an elemental-abundance analysis, in the near-ultraviolet (NUV) spectral range, for the extremely metal-poor star BD+44 493, a 9th magnitude sub-giant with [Fe/H] = -3.8 and enhanced carbon, based on data acquired with the Space Telescope ...

Modeling of the Super-Eddington Phase for Classical Novae: Five IUE Novae

, 2006
We present a light curve model for the super-Eddington luminosity phase of five classical novae observed with IUE. Optical and UV light curves are calculated based on the optically thick wind theory with a reduced effective opacity for a porous ...

MINERAL ABSORBENT EFFIECIENCY ON THE PETROLEUM SPILLS REMOVAL

Studia Universitatis Babes-Bolyai Chemia
Mineral absorbents are of great interest for the oil spills removal. Therefore, current investigation tests the removal ability of three commercial products: Zeolit Spectrum, Favisan Clay and professional oil spills removal Adabline II OS.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

High Fidelity Full-Color Optical Sectioning Structured Illumination Microscopy by Fourier Domain Based Reconstruction

Photonics
The natural color of biological specimens plays a crucial role in body protection, signaling, physiological adaptations, etc. Full-color optical sectioning structured illumination microscopy (OS-SIM) color is a promising approach that can reconstruct ...

The absorption spectrum around nu=1: evidence for a small size Skyrmion

, 2004
We measure the absorption spectrum of a two-dimensional electron system (2DES) in a GaAs quantum well in the presence of a perpendicular magnetic field. We focus on the absorption spectrum into the lowest Landau Level around nu=1.

General Relativistic Radiative Transfer [PDF]

, 2006
We present a general method to calculate radiative transfer including scattering in the continuum as well as in lines in spherically symmetric systems that are influenced by the effects of general relativity (GR).

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
