Vascular endothelial growth factor immunoexpression in oral paracoccidioidomycosis.

Background: Paracoccidioidomycosis (PCM) is a systemic mycosis endemic and limited to Latin America. Brazil is responsible for more than 80% of diagnosed cases in the world. Since PCM is not a notifiable disease, there are still no accurate data on its incidence in Brazil.

Biological Behavior of Bioactive Glasses SinGlass (45S5) and SinGlass High (F18) in the Repair of Critical Bone Defects.

This study evaluated the osteogenic potential of the bioactive glasses SinGlass (45S5) and SinGlass High (F18) in regenerating critical bone defects in rat calvaria. Both biomaterials promoted new bone formation around the particles, with the SinGlass High (F18) group exhibiting a higher rate of bone maturation. Histomorphological and birefringence analyses revealed better organization of the newly formed bone in the biomaterial-treated groups, and immunohistochemistry indicated the expression of osteogenic markers such as osteocalcin, immunostaining for bone morphogenetic protein 2 (BMP 2), and immunostaining for bone morphogenetic protein 4 (BMP 4).

Gene transcription in the oyster Crassostrea gigas exposed to environmental concentrations of the UV filter Benzophenone-3.

Personal care products (PCPs), such as sunscreens, are usually found in various aquatic ecosystems at low concentrations (ng l to µg l). However, there is limited information regarding their effects on marine bivalves. Therefore, the aim of this study was to evaluate the sublethal effects of environmental concentrations (1 and 100 µg l) of benzophenone-3 (BP-3) in Crassostrea gigas oysters after 1 and 7 days of exposure.

Death Anxiety Among Users and Non-Users of Psychedelics.

This study is a survey-type, cross-sectional study conducted in Brazil ( = 517), with online data collection taking place from April to June 2022. The main objective of this study was to evaluate the death anxiety in users and non-users of psychedelics. To this end, we also assessed the validity and reliability of the Death Anxiety Scale in Brazil.

Exploring Brazilian Immigrant Mothers' Beliefs and Practices Regarding Their Preschool Children's Oral Health: A Qualitative Study Conducted in the United States.

Parents' beliefs and practices significantly shape young children's oral health (OH), particularly during preschool years when these habits are being established. Immigrant parents often face challenges in promoting OH due to cultural, financial, and logistical barriers. This qualitative study explored OH beliefs, practices, and barriers among Brazilian immigrant mothers in the United States (U.
