Gonatobotryum is an anamorphic fungus reported mainly as a saprophyte, parasite, or endophyte. The genus has traditionally been identified based on morphological features, with its phylogenetic placement remaining uncertain due to the lack of molecular data. During the analysis of fungi obtained from mangrove sediments in Brazil, nine isolates were morphologically identified as Gonatobotryum and subsequently analysed using the...
Viruses from wild plants may emerge as new economically important agricultural pathogens through spillover events. Blainvillea yellow spot virus ( Begomovirus blainvilleae , BlYSV) is a bipartite geminivirus which is ubiquitous in the non-cultivated plant Blainvillea rhomboidea . To better understand the ecological and evolutionary aspects of this virus, we sampled B. rhomboidea in three Brazilian states between 2020 and 2023....
Environmental stress is a fundamental facet of life and a significant driver of natural selection in the wild. Gene expression diversity may facilitate adaptation to environmental changes, without necessary genetic change, but its role in adaptive divergence remains largely understudied in Neotropical systems. In Amazonian riparian forests, species distribution is predominantly influenced by species' waterlogging tolerance. Th...
Uncalibrated Single-Camera View Video Tracking of Head Impact Speeds Using Model-Based Image MatchingNARA Subscribed
Purpose This study evaluates the accuracy of a model-based image matching (MBIM) approach with model calibration for tracking head impact speeds in uncalibrated spaces from single-camera views. Methods Two validation datasets were used. The first included 36 videos of guided NOCSAE headform drops at varying camera positions (heights, distances, camera angles) where a speed gate measured vertical impact speed. The second datase...
Natural compounds-based nanomedicines for cancer treatment: Future directions and challengesNARA Subscribed
Several efforts have been extensively accomplished for the amelioration of the cancer treatments using different types of new drugs and less invasives therapies in comparison with the traditional therapeutic modalities, which are widely associated with numerous drawbacks, such as drug resistance, non-selectivity and high costs, restraining their clinical response. The application of natural compounds for the prevention and tre...
