The Effectiveness of Remineralization with Compound Silver Nanoparticles and Fluoride Varnish in Carious Lesions in Primary Teeth: A Randomized Split-Mouth Clinical Trial.

Anti-cariogenic properties of silver nanoparticles and fluorides have been probed mainly in vitro and with the objetive to evaluate the remineralizing effects of an applied silver nanoparticle compound plus fluoride varnish, a randomized split-mouth clinical trial was conducted in children aged 6 to 7 years. : The project was approved by the ethics committee of the faculty. Primary molars were randomly distributed into two groups, as follows: Group A was treated with a compound based on silver nanoparticles plus fluoride varnish (SNP-FV), and Group B was treated with a silver diamine fluoride compound (SDF-KI), which is the current standard treatment.

Relationship between Social Support Networks and Physical Functioning in Older Community-Dwelling Mexicans.

Some studies have demonstrated the relationship between social support networks (SSNs) and health status. In this sense, it has been considered that physical and mental functioning is a key indicator of the health in the age people. The aim of this study was to determine the association between social support networks and physical functioning.

Prevalence of thyroid dysfunction and its impact on cognition in older mexican adults: (SADEM study).

Introduction: Subclinical thyroid dysfunction is a possible risk factor for cognitive impairment in old age, but results are inconsistent. Aim of the present study was to evaluate the prevalence of thyroid dysfunction among older community-dwelling adults and to see whether thyroid function impacts the cognitive status of the elderly.

Methods: We included 1750 participants from the Study on Aging and Dementia in Mexico (SADEM).

Pyrimethamine induces oxidative stress in Plasmodium yoelii 17XL-infected mice: a novel immunomodulatory mechanism of action for an old antimalarial drug?

Pyrimethamine is an antimalarial drug that has also been used successfully to treat autoimmune diseases such as lymphoproliferative syndrome. In this work, the effect of pyrimethamine (PYR) on the production of free radicals in malaria-infected mice was studied to better understand the drug's immunomodulatory properties. BALB/c and CBA/Ca mice were infected with Plasmodium yoelii 17XL.
