Purpose: This study utilized cone-beam computed tomography images to assess the potential of maxillary sinus (MS) and piriform aperture (PA) measurements in sex prediction and to identify possible correlations between these structures and the MS ostium.
Methods: A total of 204 images were selected and divided into two groups: 102 for constructing and testing the formula, and 102 for validation. In each subgroup, the images were equally divided for 11 measurements by two examiners in the MS (height, width, length, and total width), PA (height and width), and maxillary ostium diameter.
Article Synopsis
- Tropical biodiversity is facing significant changes due to intensified hydrological cycles, resulting in more severe droughts and wet seasons, which raises concerns about the resilience of ecosystems.
- A 20-year study in Central Amazonia assessed the impacts of these climate changes on bird, fish, ant, and palm communities, revealing distinct responses where animals were more affected by sudden climate extremes, while palm species showed more stability over time.
- The research indicated that while the 'insurance effect' helped moderate long-term impacts of climate events on biodiversity, the anticipated 'environmental refugia' did not effectively protect species during extreme weather conditions, highlighting the complex resilience of ecosystems amidst climate change.
The fractures in the condylar area are a challenge for every surgeon, for the treatment of which trapezoidal condylar plate is used in most cases. However, it is not possible to position the plate in the ideal osteosynthesis lines according to Meyer et al. in every clinical situation.

The lack of synthesized information regarding biodiversity is a major problem among researchers, leading to a pervasive cycle where ecologists make field campaigns to collect information that already exists and yet has not been made available for a broader audience. This problem leads to long-lasting effects in public policies such as spending money multiple times to conduct similar studies in the same area. We aim to identify this knowledge gap by synthesizing information available regarding two Brazilian long-term biodiversity programs and the metadata generated by them.
