Biomaterials in ophthalmology: human cornea bioengineering

Medical engineering, as an auspicious conjunction between healthcare practice, biotechnology and materials science, has emerged over time with the aim to improve human’s health. Cornea, an essential part of the eye responsible for most of its optical power, suffers every day due to accidents or various diseases. To avoid complications and overcome limitations of conventional transplantation and other surgical procedures, biomaterials and bioprinting proved beneficial can be used to design optimal devices for corneal implantation. During medical evolution, biopolymers have been used especially in tissue engineering applications, due to their high elasticity and flexibility, adaptable optical properties and tunable microstructure. Natural polymers are well accepted by the body, their offer support for tissue regeneration and, in most cases, they are easy to obtain. Beside natural-derived biopolymers, synthetic polymers can be used in bioprinting to develop performance-enhanced platforms for corneal bioengineering. Bioprinting represents an innovative method to obtain a corneal implant and has the advantage to enable the facile control over some specific properties, such as thickness, color, elasticity or shape.

The importance of oxygen release in diabetic foot ulcer wounds

Oxygen is the essential element required for proper physiological function of cells, tissues and organs within healthy human body. Thanks to its intricate structure, the skin provides a multiprotective barrier against traumatic and non-traumatic injuries, but also a complex and successful self-healing process of the affected tissue. In the particular case of chronic skin wounds, such as diabetic foot ulcer wounds, there is an immediate demand to develop alternative procedures that prevent infection, speed up healing and eliminate any disrupting factor that may interfere with the therapeutic process. Given the importance of oxygen during wound healing cascade, impressive attention was oriented towards the fabrication of oxygen-releasing wound dressings.

Bioengineering International joins the Family of Platinum Open Access Journals

We are pleased to announce the launch of a new platinum open access journal entitled Bioengineering International. Bioengineering International is a peer-reviewed journal that encourages worldwide academic and scientific researchers to share their original research work, reviews and commentaries. The journal will provide an extensive platform for this interdisciplinary blend of chemistry, biology and materials science, with their synergistic effects on the progress of biomedicine and bioengineering. The purpose of Bioengineering International journal is to provide comprehensive and facile access to the latest contributions of academic and scientific researchers and to facilitate their publication completely free of charge including review papers, original research articles, communications and short notes. AMG Transcend Association (Romania) covers all economic costs of the publishing process. Platinum Open Access policy provides permanent free and open access for worldwide readers, both the scientific community and the general public. The Bioengineering International journal will ensure the high visibility of the published papers, by ensuring their appearance in most important scientific databases, such as Scopus (Elsevier), Science Citation Index (Clarivate Analytics), Scilit (MDPI) and Chemical Abstracts (CAS). Therefore, we encourage all research scientists interested in the field of bioengineering to submit their papers to Bioengineering International.
