Electrosprayed polymeric nanobeads and nanofibers of modafinil: preparation, characterization, and drug release studies [PDF]

open access: yesBioImpacts, 2019
Introduction: Modafinil (MDF) is used orally for the treatment of attention-deficit/hyperactivity disorder and narcolepsy. It holds low solubility and high permeability; therefore, improving its dissolution properties by preparing nanoformulations can be

Repeated thermo-hydrolytic disintegration of medium density fibreboards (MDF) for the production of new MDF [PDF]

open access: yesEuropean Journal of Wood and Wood Products, 2021
AbstractMedium density fibreboards (MDF) are currently not recycled after service life, but various publications report on recycling by the disintegration of MDF using various techniques and the properties of obtained recovered fibres (RF). In this study, the main aim was to put back RF into the MDF manufacturing process as closed-loop recycling using ...

Freeze-Dried Ham Promotes Azoxymethane-Induced Mucin-Depleted Foci and Aberrant Crypt Foci in Rat Colon [PDF]

open access: yes, 2010
Processed and red meat consumption is associated with the risk of colorectal cancer. Meta-analyses have suggested that the risk associated with processed meat is higher. Most processed meats are cured and cooked, which leads to formation of free nitrosyl

Cosmic stellar relics in the Galactic halo [PDF]

open access: yes, 2006
We study the stellar population history and chemical evolution of the Milky Way (MW) in a hierarchical LCDM model for structure formation. Using a Monte Carlo method based on the semi-analytical EPS formalism, we reconstruct the merger tree of our Galaxy
