Effects of adding graphene fibers to polymethyl methacrylate on biocompatibility and surface characterization.

Statement Of Problem: Interim fixed prostheses are used provisionally to provide esthetics and maintain function until placement of the definitive prosthesis. Polymethyl methacrylate (PMMA) has been widely used as an interim material but has mechanical limitations that can be improved with the addition of nanomaterials such as graphene fibers (PMMA-G). However, studies on the biocompatibility of this material are lacking.

The Influence of the Thickness of the Materials for the Provisionalization in Minimally Invasive Restorations.

This in vitro study aimed to determine the flexural strength and modulus of elasticity of two bisacrylic resins for temporary crowns at different thicknesses, i.e., Structur 3 and Structur Premium, and to compare them with each other.

Factors Involved in Endothelial Dysfunction Related to Angiogenic Disbalance and Oxidative Stress, in Women at High Risk of Term Pre-Eclampsia.

Oxidative and inflammatory stress, angiogenic imbalance, and endothelial dysfunction are pathophysiological mechanisms occurring in pre-eclampsia (PE) that may persist over time and predispose women to a higher risk of cardiovascular disease (CVD) in the future. However, there is little evidence on the vascular function of women at risk of PE who have not developed the disease. The main objective of this research is to study factors and biomarkers involved in endothelial dysfunction related to oxidative stress, angiogenic disbalance, and inflammation in women at high risk of term PE who do not develop the disease.

Current Status of the Hypothesis of a Claustro-Insular Homolog in Sauropsids.

The author previously worked extensively on the broad problem of the evolution of the vertebrate pallium. He proposed various Bauplan models covering at least gnathostomes, based in the definition of a set of pallial sectors with topologically invariant positional relationships and distinct molecular profiles. Out of one of these models, presented as the "updated tetrapartite pallium model," a modified definition of the earlier lateral pallium sector (LPall) concept emerged, characterizing it in mammals as an unitary claustro-insular transitional (mesocortical) complex intercalated between the neocortex or dorsal pallium (DPall) above and olfactory cortex or ventral pallium (VPall) underneath.

Social distancing at health care centers early in the pandemic helps to protect population from COVID-19.

The impact of COVID-19 outbreak has been unequal across Spanish regions. The epidemic wave has been smoother in the Region of Murcia (RM) (6 deaths/100,000 residents). Physical distance from health centers from day 0 is an additional social distancing measure that confers an advantageous starting position in the fight against COVID-19.

Environment, lifestyle behavior and health-related quality of life in childhood and adolescent cancer survivors of extracranial malignancies.

Background: Childhood cancer is a chronic disease with high survival rates. Childhood cancer survivors (CCS) can still face health effects later in their lives. Health-related quality of life (HRQoL) and the factors that modify it allow CCS and their families to improve care in the long-term follow-up.

Secondhand smoke: A new and modifiable prognostic factor in childhood acute lymphoblastic leukemias.

Background: The 5-year overall survival (OS) in childhood acute lymphoblastic leukemia (ALL) has reached 90% in high-income countries, levels that can no be longer overcome with strategies based on intensification of treatment. Other approaches in the search for new and modifiable prognostic factors are necessary to continue to improve these rates. The importance of environmental factors in the etiopathogenesis of childhood ALL has been regaining interest but its role in the prognosis and survival of this disease is not well explored.
