By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Automated Profiling of Social Behaviors to Assess the Genetic Basis of Evolution of Aggressive Behaviors in Astyanax mexicanus

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Across the animal kingdom, social behaviors such as aggression are critical for survival and reproductive success. While there is significant variation in social behaviors within and between species, the genetic mechanisms underlying natural variation in social behaviors are poorly understood.

Wheat flour particle size: Influence of mill design and effects on quality and performance

open access: yesJSFA reports, EarlyView.
Abstract Among the various characteristics of wheat (Triticum aestivum) flour, particle size is of paramount importance globally. The industrial process of separating the three main components (endosperm, bran, and germ) must ensure that the desired quality is delivered to customers through a progressive reduction in the size of the endosperm until the

Spatially optimized gene transfection by laser-induced breakdown of optically trapped nanoparticles [PDF]

open access: yes, 2014
We demonstrate laser-induced breakdown of an optically trapped nanoparticle with a nanosecond laser pulse. Controllable cavitation within a microscope sample was achieved, generating shear stress to monolayers of live cells. This efficiently permeabilize
