Phosphorus Release from Nano-Hydroxyapatite Derived from Biowastes in the Presence of Phosphate-Solubilizing Bacteria: A Soil Column Experiment.

Phosphorus applications in agriculture can lead to significant environmental impacts, necessitating a revolution in current agricultural practices. This study explores the potential of hydroxyapatite nanoparticles (nHAPs) synthesized from poultry bones as P fertilizers. nHAPs were produced at 300 °C (nHAP) and 700 °C (nHAP), and their effectiveness was evaluated.

Association between socioeconomic contextual factor, dental care service availability, and prevalence of periodontitis in Brazil: a multilevel analysis.

This study aimed to examine the effect of dental care services on periodontitis cases in Brazilian municipalities. The sample comprised 3,426 individuals aged 35-44 years. Moderate to severe periodontitis with clinical attachment loss and probing depth was the dependent variable, both > 3mm.

Lignin-based nano-enabled agriculture: A mini-review.

Nowadays sustainable nanotechnological strategies to improve the efficiency of conventional agricultural practices are of utmost importance. As a matter of fact, the increasing use of productive factors in response to the growing food demand plays an important role in determining the environmental impact of agriculture. In this respect, low-efficiency conventional practices are becoming obsolete.

Contextual determinants for use of dental services according to different healthcare financing systems: Andersen's model.

Objectives: To explore contextual factors associated with overall dental service use, and investigate whether these factors influenced choice of the type of service according to the healthcare financing alternatives (public services; out-of-pocket services; and private health insurance), by adults and older individuals, based on the most recent Andersen's behavioural model.

Methods: Cross-sectional study with individual data on 17,305 adults from 177 Brazilian municipalities in the National Oral Health Survey (SBBrasil 2010). Municipal-level information was obtained from health information systems and census data.

Use of dental services by disability status in Brazil in 2013.

Objective: To describe the prevalence and factors associated with the use of oral health services in people with and without disabilities in Brazil.

Methods: A cross-sectional study was used with the secondary data of 60,202 individuals from the Brazilian National Health Survey of 2013. The main exposure variable was 'Disability', and the main outcome was 'Dental service use'.
