Stem cell-derived secretome reduces dermonecrosis caused by spider venom

The image shows two live Loxosceles intermedia spiders from the Ezequiel Dias Foundation (FUNED) in Belo Horizonte, MG, Brazil. On the left side (A), we see a male specimen, which is smaller and has a slimmer abdomen. On the right side (B), there is a female specimen, which is larger and has a more rounded and voluminous abdomen. Both spiders have a brown coloration, long and thin legs, and bodies with characteristics typical of the species.

By investigating the protective effects of secretome-derived mesenchymal stromal cells on dermonecrosis caused by Loxosceles intermedia venom in rabbits, it was observed that treated groups showed milder local effects and swelling compared to controls, which highlights the potential of stem cell-derived secretome for treating dermonecrotic lesions.

Functional foods containing probiotics are innovative and offer health benefits

Variety of dairy products, including milk in bottles and a glass, various cheeses, yogurt in containers, and a bowl of cottage cheese displayed on a white background.

The dairy market faces a growing demand for new functional foods. In response, the use of lactic acid bacteria in fermented products is promising, as it provides various health benefits and offers a wide range of compounds. Read More →

Active surveillance is cheaper than immediate surgery in low-risk papillary thyroid microcarcinoma

When comparing long-term medical costs of active surveillance (AS), partial thyroidectomy, and total thyroidectomy in patients with low-risk papillary thyroid microcarcinoma that receives care covered by their Public Health System, researchers concluded that the AS approach was less costly than immediate surgery over a 30-year follow-up period.

Editorial policies for inclusion and diversity in the Revista Brasileira de Estudos da Presença

Part of the cover of Revista Brasileira de Estudos da Presença, vol. 7, no. 2, 2017, displaying a painting of the face of a Black person.

The Revista Brasileira de Estudos da Presença has implemented important changes by adopting Open Science practices with a focus on IDEIA principles, being a pioneer in the area of Performing Arts in Brazil. Prior to this, the journal already followed similar principles, as evidenced by the thematic section “Performance and Ethnic-Racial Relations”, published in 2017. Read More →

Metamorphosis, friction or symbiosis between body and animated forms in the work of Ilka Schönbein

Black and white photograph of the show "Métamorphoses" by Ilka Schönbein, in which slightly macabre-looking puppets and marionettes are on a wooden platform, being manipulated by the artist.

The works of puppeteer and dancer Ilka Schönbein challenge perceptions of life and death, provoking reflections on eroticism and finitude. Her creations reveal a poetic singularity that provokes disquieting strangeness in the relationship between the human and the animate. Read More →

Performing Arts research highlighted on the blog “SciELO in Perspective”

Photomontage of four issues of the “Brazilian Journal of Presence Studies”, showing different covers with different themes and people. In the center, there is a vertical column with three stylized “P*” logos; the logos at the ends are black, while the central logo is white.

The Revista Brasileira de Estudos da Presença Special Week, taking place this week, will explore themes such as the notion of presence, methodological diversity, and social issues in Performing Arts research. The program includes analyses, discussions and a detailed overview of the journal’s social impact, highlighting its importance and activities within the scope of Open Science. Read More →

Tick vaccine could be an effective solution for agriculture and livestock

Although the use of acaricides is the main strategy for controlling infestations of R. microplus, researchers have been investigating vaccines as a promising alternative, as they offer several advantages, such as preventing the selection of drug-resistant tick populations and reducing the presence of acaricide residues in milk, meat, and the environment.

It is now possible to develop an accessible passenger cabin for people with physical and sensory disabilities

Photograph of the interior of an airplane, showing the blue seats arranged along the cabin.

The difficulties faced by passengers with reduced mobility or sensory losses cause people with disabilities to forgo air travel. By mapping these users’ needs and based on technologies already available in the aviation industry, Brazilian researchers demonstrate that airlines can develop an accessible cabin. Read More →

An Analysis of the Epistemological Foundations of Machine Learning

Photograph of a robotic hand and a human hand reaching towards each other against a plain background, nearly touching fingertips.

Outlined here is a critical review of the logical-epistemic foundations of machine learning, focusing on the limitation of AI systems’ autonomy in generating knowledge. It contrasts this possibility with the theoretical constraints posed by Chaitin’s incompleteness theorem, which argues that AI cannot surpass human cognitive capacity. Read More →

Barnyardgrass resistance to herbicides demands new agricultural strategies

Photograph of a pair of gloved hands holding freshly picked herbs or plants, with more greenery visible in the background.

A recent evaluation of the occurrence of cross-resistance in barnyardgrass biotypes from the main rice-growing regions of Santa Catarina state to ACCase inhibitors detected a biotype of Echinochloa crus-galli with multiple resistance to the herbicides quinclorac (cellulose biosynthesis inhibitor), penoxsulam (ALS inhibitor) and cyhalofop-butyl (ACCase inhibitor).
