Estudio experimental de la alteración de la mojabilidad mediante el uso de un surfactante extraído del aceite del pino TOFA en el sistema crudo liviano/agua/SiO2 [PDF]

Avances en Química, 2012
It is known that much of the oil is trapped in reservoirs after use of conventional methods for oil extraction. However, several methods have been introduced to increase the recovery of this oil, one of them is through the alteration of the wettability.

Application of the Principles of Green Chemistry for the Development of a New and Sensitive Method for Analysis of Ertapenem Sodium by Capillary Electrophoresis

International Journal of Analytical Chemistry, Volume 2019, Issue 1, 2019., 2019
An innovative method is validated for the analysis of ertapenem sodium by capillary electrophoresis using potassium phosphate buffer 10 mM pH 7 and 15 kV voltage, in the concentration range of 70 to 120 μg mL−1. Ertapenem had a migration time of 3.15 minutes and the linearity curve was y = 2281.7 x ‐ 24495 with a R2 = 0.9994. Thus, we propose a routine

Influence of the Temporomandibular Joint in the Estimation of Bone Density in the Mandible through a Bone Remodelling Model

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
The temporomandibular joint (TMJ) plays a key role in the distribution of stresses in the mandible during mastication and consequently in the distribution of bone density, due to the interconnection between both variables through bone remodelling. Two finite element models of the mandible were compared to study the influence of the redistribution of ...

Histopathological and Reproductive Evaluation in Male Rats Fed Jatropha curcas Seed Cake with or without Alkaline Hydrolysis and Subjected to Heat Treatment

BioMed Research International, Volume 2017, Issue 1, 2017., 2017
Jatropha curcas cake, a by‐product of biodiesel production, is rich in protein and has potential to be used in livestock feed; however, the presence of antinutritional factors and phorbol esters limits its use. Thus, this study investigated toxicological and reproductive effects in male Wistar rats after subchronic exposure to J.

In vitro antimicrobial activity of a gel containing antimicrobial peptide AMP2041, chlorhexidine digluconate and Tris‐EDTA on clinical isolates of Pseudomonas aeruginosa from canine otitis

Veterinary Dermatology, Volume 27, Issue 5, Page 391-e98, October 2016., 2016
Background– Pseudomonas aeruginosa (PA) may cause suppurative otitis externa with severe inflammation and ulceration in dogs. Multidrug resistance is commonly reported for this organism, creating a difficult therapeutic challenge. Objective– The aim of this study was to evaluate the in vitro antimicrobial activity of a gel containing 0.5 µg/mL of ...

Dragging Human Mesenchymal Stem Cells with the Aid of Supramolecular Assemblies of Single‐Walled Carbon Nanotubes, Molecular Magnets, and Peptides in a Magnetic Field

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
Human adipose‐derived stem cells (hASCs) are an attractive cell source for therapeutic applicability in diverse fields for the repair and regeneration of damaged or malfunctioning tissues and organs. There is a growing number of cell therapies using stem cells due to their characteristics of modulation of immune system and reduction of acute rejection.
