Phytochemical screening and biological properties of Quintral flower polyphenolic fractions.

flower is used in traditional medicine for its antioxidant and antibacterial properties, which are attributed to phenolic compounds. These compounds present different grades of associations with the plant matrix (free, esterified, and insoluble). This study aimed to determine which fraction contributes the most to total phenolic and flavonoid contents and bioactive properties.

Nanostructured Conducting Polymers and Their Applications in Energy Storage Devices.

Due to the energy requirements for various human activities, and the need for a substantial change in the energy matrix, it is important to research and design new materials that allow the availability of appropriate technologies. In this sense, together with proposals that advocate a reduction in the conversion, storage, and feeding of clean energies, such as fuel cells and electrochemical capacitors energy consumption, there is an approach that is based on the development of better applications for and batteries. An alternative to commonly used inorganic materials is conducting polymers (CP).

Traumatic pseudoaneurysm in brachial artery after removal of a subdermal contraceptive implant.

The frequency of invasive therapeutic procedures has increased as medicine evolves, and the number of complications related to them has increased as a consequence. Subdermal contraceptive implants (SCI) offer benefits for female contraception, but implant and removal are associated with a complication rate of around 3%. In this article, we report and discuss a case of traumatic brachial artery pseudoaneurysm after an attempt to remove an SCI, complicated by compression of the median nerve.

The performance of truth: politicians, fact-checking journalism, and the struggle to tackle COVID-19 misinformation.

Since the World Health Organization (WHO, February 2, 2020) reported that the spread of coronavirus disease has been accompanied by a "massive infodemic," the COVID-19 outbreak has become a national and international battleground of a struggle against misinformation. Fact-checking outlets around the world have been actively counteracting false and misleading information surrounding the pandemic. In this article, we conceptualize fact checkers in terms of the "interpretative power" that journalism holds in processes of political performances (Alexander in Soc Theory 22(4): 527-573, 2004, in: The performance of politics.

Identifying Risk Profiles for Antisocial Behavior in a Spanish Sample of Young Offenders.

One of the main purposes of juvenile risk assessment is to distinguish different risk profiles, which may lead to referring youths into specific intervention programs tailored to their specific needs. This study is devoted to identifying main typologies of risk in a sample of 286 Spanish young offenders aged 14 to 22 ( = 17.36; = 1.
