Green Synthesis of FeO Nanoparticles Using Leaf Extract on Sawdust for Cationic Dye Adsorption.

The present study reports the synthesis of FeO nanoparticles on sawdust (FeO@PS) using a leaf extract. The morphology and structure of FeO@PS were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and UV-Vis diffuse reflectance. The adsorption capacity of the system was evaluated by testing its ability to remove the Rhodamine B (RhB) dye.

Dental caries lesions and impact on quality of life in adolescents living in urban and rural areas. A case study.

The concept of quality of life (QoL) developed from early studies on subjective wellbeing and satisfaction with life, interpreted as resulting from living conditions, and recognized by means of objective indicators. Indicators have been developed and validated to measure the relationship between quality of life and health Aim: To determine, during an Educational Social Practice, the association between presence of dental caries lesions and its impact on quality of life of adolescents living in rural and urban areas in Argentina. Materials and Method: This was an observational cross-sectional study in (a) a rural area (Tres Isletas; Chaco Province/Schools No.

Social Inequalities and Geographical Distribution in Caries Treatment Needs among Schoolchildren Living in Buenos Aires City: A Cross-Sectional Study.

Background: Caries experience in Argentine children is quite high and no national data are present.

Aim: This cross-sectional observational survey aimed to assess the oral health status of schoolchildren in Buenos Aires (CABA) using CTNI and to evaluate the ecological association between health inequalities and caries prevalence.

Design: Data were collected, via a clustered procedure, during the 2016-2018 school years.

Structure of the RNA-dependent RNA polymerase P2 from the cystovirus φ8.

The replication of RNA viruses relies on the activity of RNA-dependent RNA polymerases (RdRps). Despite large variations in their genomic sequences, viral RdRps share a common architecture generally known as a closed right hand. The P2 polymerase of cystovirus φ6 is currently among the best characterized viral RdRps.
