A Finite Element Method for Modeling Diffusion and Drug Release from Nanocellulose/Nanoporous Silicon Composites.

: A previous study investigated the in vitro release of methylene blue (MB), a widely used cationic dye in biomedical applications, from nanocellulose/nanoporous silicon (NC/nPSi) composites under conditions simulating body fluids. The results showed that MB release rates varied significantly with the nPSi concentration in the composite, highlighting its potential for controlled drug delivery. To further analyze the relationship between diffusion dynamics and the MB concentration, this study developed a finite element (FE) method to solve Fick's equations governing the drug delivery system.

International adaptation of Meaning-Centered Psychotherapy for Latinos: Providers' views on pre-implementation.

Background: This qualitative study aims to identify facilitators of and barriers to the implementation of Meaning-Centered Psychotherapy (MCP) by providers of mental health services to Latinos in the US and Latin America using the practical, robust implementation and sustainability model (PRISM). This information will be used to increase usability and acceptability of MCP for Latino patients with cancer and their providers in Latin America and the US.

Methods: A total of 14 Latino cancer patient mental health providers completed in-depth semi-structured interviews.

Consumer Protection in Peru: Origins, Evolution, and Main Regulatory Influences.

In the following text, the authors address the origins and evolution of consumer protection in Peru, as well as highlighting the main regulatory influences of the current 2010 Consumer Protection and Defence Code with regard to consumer sales (defective products), and the regime of abusive clauses, to which is added a reference to protection of personal data.

Early evidence and predictors of mental distress of adults one month in the COVID-19 epidemic in Brazil.

Objective: We aim to provide early evidence of mental distress and its associated predictors among adults one month into the COVID-19 crisis in Brazil.

Methods: We conducted an online survey of 638 adults in Brazil on March 25-28, 2020, about one month (32 days) cross-sectionally after the first COVID-19 case in South America was confirmed in São Paulo. The 638 adults were in 25 states out of the 26 Brazilian states, with the only exception being Roraima, the least populated state in the Amazon.

To which world regions does the valence-dominance model of social perception apply?

Over the past 10 years, Oosterhof and Todorov's valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions.

Nitrogen and metal pollution in the southern Caspian Sea: a multiple approach to bioassessment.

The Caspian Sea hosts areas of high ecological value as well as industrial, leisure, and agricultural activities that dump into the water body different kinds of pollutants. In this complex context, a proper description of the origin and potential sources of pollution is necessary to address management and mitigation actions aimed at preserving the quality of the water resource and the integrity of the ecosystems. Here, we aimed at detecting sources of both nitrogen inputs, by N stable isotope analysis of macroalgae, and metals in macroalgae and sediments in two highly anthropized coastal stretches at the Iranian side of the Caspian Sea.

A Study on the Biodiversity of Pigmented Andean Potatoes: Nutritional Profile and Phenolic Composition.

The characterization of six varieties of native Andean potatoes with a wide biodiversity in tuber shape, flesh, and skin color was performed, through the determination of their proximate composition, mineral content, and phenolic profile. Minerals concentration revealed significant genotypic variation. Potassium was the most abundant element in all varieties, ranging from 7272.

Glyceridic and Unsaponifiable Components of Microencapsulated Sacha Inchi ( L. and L.) Edible Oils.

Sacha inchi ( L. and L.) edible oils were microencapsulated and the lipid fraction of the microparticles was characterized.

[Identity Development, Family Relations, and Symptomatology in Adolescents from Seven Countries].

Identity Development, Family Relations, and Symptomatology in Adolescents from Seven Countries This study analyzed identity development and parental rearing in adolescents from seven countries. In a sample of 2,259 adolescents (M = 15 years; 54 % female) from France, Germany, Turkey, Greece, Peru, Pakistan, and Poland, maternal parenting (support, psychological control, anxious rearing), identity development (exploration, commitment and ruminative exploration) and psychopathology was assessed. Adolescents from central Europe (France and Germany) were characterized by quite low scores in most identity dimensions, compared to adolescents from all other countries.

Prevalence of problematic cell phone use in an adult population in Spain as assessed by the Mobile Phone Problem Use Scale (MPPUS).

Problematic cell phone use has alarmingly increased in industrialized countries in the past 10 years. For many perpetrators, it can turn into a behavioural addiction, although this is not a recognized medical condition. Although there are many tools for evaluating this use, one of the most widely used tools is the Mobile Phone Problematic Use Scale (MPPUS), which we test on a representative sample of the population in Spain to obtain an estimate of the prevalence of problematic cell phone use in our midst.
