Current heart valve prostheses represent a 50% reduction in life expectancy for young patients, especially children. The thromboembolic complications, which is the formation of blood clots that travel through the bloodstream that could block the arteries, and induce the formation of calcium deposits on the valve limit the durability of the device ending on an unavoidable replacement of the valve, inducing unnecessary stress on the patient, risking their life. The search for an ideal aortic valve substitute has been going on for more than … Seguir leyendo Biomaterials for heart valve prostheses: Could this approach increase heart-diseased children life expectancy?

One of the main health issues in Mexico is the lack of available prostheses due to the cost of the devices and the procedure to make the implantation. This problem has encouraged researchers to review traditional biomaterials and to look for more affordable alternatives.    To begin, the biomaterial concept must be defined. According to the National Institute of Biomedical Imaging and Bioengineering (2020), biomaterials are “any matter, surface, … Seguir leyendo Analysis of Polylactic Acid, Bioglass and Hydroxyapatite coating as biomaterials for the development of prostheses

According to Mayo Clinic, a stroke is a medical event that occurs when blood supply is interrupted or reduced in a part of the brain, which blocks brain tissue from oxygenation and nutrients, leading to tissue death and causing brain damage. Nowadays, less patients die from a stroke; however, it is one of the leading causes of disability in adults, since approximately 15 million people in the world suffer from a stroke every year, as the … Seguir leyendo Hyaluronic acid based microporous annealed particle (HA-MAP) as an alternative for stroke treatment

Sutures are primarily used in surgery to draw tissues together. Almost all sutures only play the role of mechanically tie wound tissues together, but they do not have additional functions. For this reason, hybrid sutures with targeted mechanical properties and biological activities are of great interest (Hu & Huang, 2010). Tendons and cartilages repair remain a challenging clinical problem and a crucial medical need, as the cases involving loss of … Seguir leyendo Bio-absorbable sutures: a novel development in surgical repair of tendon tissue

Rheumatoid arthritis (RA) is a chronic disease that causes destruction of bone and articular cartilage. It is a condition that results in an important target on the field for the development of biomaterials aiming to improve the health of patients with RA. In a research from the “Asociación Mexicana de Familiares y Pacientes con Artritis Reumatoide” (AMEPAR) (2017), it was found that Mexico has a prevalence of 1.6%, which ranks this country within the range of countries … Seguir leyendo BPN/PRP chitosan hydrogel in the treatment against Rheumatoid Arthritis
