Biopolymeric Fibrous Aerogels: The Sustainable Alternative for Water Remediation.

The increment in water pollution due to the massive development in the industrial sector is a worldwide concern due to its impact on the environment and human health. Therefore, the development of new and sustainable alternatives for water remediation is needed. In this context, aerogels present high porosity, low density, and a remarkable adsorption capacity, making them candidates for remediation applications demonstrating high efficiency in removing pollutants from the air, soil, and water.

Fast cyclical-decellularized trachea as a natural 3D scaffold for organ engineering.

Commonly reported decellularization protocols for trachea may take up from several weeks to months in order to remove the cellular materials. Two years ago, we significantly reduced the time of decellularization trachea process using trypsin. Despite the positive outcome, the protocol was useful to produce 5 cm graft length, an unsuitable length graft for most patients with tracheal disorders.

Bone loss treatment, pseudoarthrosis, arthrodesis and benign tumors using xenoimplant: clinical study.

Background: Bone loss as a result of arthrodesis, pseudarthrosis, benign tumors and bone defects was treated using a xenoimplant (Nukbone).

Methods: The effectiveness of the material was evaluated through a longitudinal and observational study at the Hospital Regional "General Ignacio Zaragoza" (HRGIZ) ISSSTE. The Mexican xenoimplant is a patent of the National Autonomous University of Mexico (UNAM).

[Mexican ceramic material for skin healing].

Sixty female Wistar rats were employed and divided into three experimental groups of 20 rats each. Groups were evaluated at 15, 30, and the last at 45 days after surgery. Each group was divided into four sets of five rats each.
