MSC‐Derived Secretome and Exosomes in Dermatology: Mechanisms, Therapeutic Opportunities, and Scientific Challenges—A Narrative Review

International Journal of Dermatology, Volume 65, Issue 2, Page 257-272, February 2026.
ABSTRACT Mesenchymal stromal cells (MSCs) exert their effects primarily through paracrine signaling via soluble factors and extracellular vesicles (EVs), especially exosomes. These acellular components offer regenerative and immunomodulatory benefits with fewer safety and logistical constraints than cell‐based therapies.

Dacarbazine as a Positive Control in Melanoma Cell Lines (A375, SK‐MEL‐103, 1205Lu) and a Human Ex Vivo Skin Model

Advanced Biology, Volume 10, Issue 1, January 2026.
The work seeked to demonstrate the drug Dacarbazine as a positive control for toxicity tests in immortalized skin cells (keratinocytes and fibroblasts) and in different neoplastic cell lines, through the assay with resazurin. In addition, an alternative model to replace animals in experimental studies, using skin explant culture (hOSEC ‐ human ...

Genetic Ancestry Reveals Historical Diversity of Formation Across Three Brazilian Communities of African Descent (Quilombos) in Central Brazil

American Journal of Human Biology, Volume 38, Issue 1, January 2026.
ABSTRACT Introduction Characterized as relatively isolated communities, many Brazilian quilombos were formed during the period of slavery in Brazil when enslaved persons (most of African descent) ran away or were abandoned by their enslavers. Quilombos in Central Brazil, whose settlement was more recent due to the relative isolation of the region ...

Peptides Derived From Reactive Center Loops Inhibit Digestive Trypsin‐Like Enzymes in Lepidopteran Pests

Archives of Insect Biochemistry and Physiology, Volume 121, Issue 1, January 2026.
Soybean yield is often reduced by pest attacks. Among these, Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) stands out as one of the most important defoliating pests of soybean. Therefore, the development of new bioinsecticides targeting Lepidopteran pests is an urgent need.

Neem oil (Azadirachta indica) as a promising feedstock for biolubricant production: enzymatic synthesis, process optimization, and molecular studies

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 237-252, January/February 2026.
Abstract The fuel industry remains closely tied to oil‐based fuels. This relationship is responsible for increasing greenhouse gas emissions. Biofuels are an alternative to petroleum‐based fuels that could make industrial production lines more sustainable.

DO ENSINO BÁSICO AO ENSINO SUPERIOR

Revista de Educação do Vale do São Francisco - REVASF, 2018
Estudos realizados no Brasil vêm mostrando que a docência apresenta vulnerabilidade ao estresse e à insatisfação no trabalho. Nessa pesquisa se analisou o ambiente laboral dos professores com base nos indicadores de Qualidade de Vida no Trabalho (QVT) e na percepção aos fatores estressores, com repercussão no seu estado geral de vida.
