In addition to the traditional treatments of cancer and cancer prevention, the use of natural compounds, especially those found in food, should be considered. To clarify if resveratrol has the potential for cancer prevention and the possibility of use in therapy, the following must be taken into account: data from epidemiology, clinical protocol (case and control), preclinical studies (lab animals), use of established cell lines as models of cancer cells, test tube assays (enzymes activities), and requirements of nanotechnologies in order to discover new drugs to fight cancer. From this perspective and future expected advances, more information is needed such as improved efficacy, methods of application, and the synergistic sensitization of resveratrol as an adjuvant. In addition, resveratrol nanoformulation is considered to overcome its weak bioavailability.

Pseudococcus calceolariae, the citrophilous mealybug, is a species of economic importance. Mating disruption (MD) is a potential control tool. During 2017–2020, trials were conducted to evaluate the potential of P. calceolariae MD in an apple and a tangerine orchard. Two pheromone doses, 6.32 g/ha (2017–2018) and 9.45 g/ha (2019–2020), were tested. The intermediate season (2018–2019) was evaluated without pheromone renewal to study the persistence of the pheromone effect. Male captures in pheromone traps, mealybug population/plant, percentage of infested fruit at harvest and mating disruption index (MDI) were recorded regularly. In both orchards, in the first season, male captures were significantly lower in MD plots compared to control plots, with an MDI > 94% in the first month after pheromone deployment. During the second season, significantly lower male captures in MD plots were still observed, with an average MDI of 80%. At the third season, male captures were again significant lower in MD than control plots shortly after pheromone applications. In both orchards, population by visual inspection and infested fruits were very low, without differences between MD and control plots. These results show the potential use of mating disruption for the control of P. calceolariae.

INTRODUCTION: Quantitative approaches to the cancer incidence and mortality of a geographic region may lack understanding of the human context in the region thereby affecting how relevant cancer prevention and control activities can best be targeted to a cancer center’s catchment area. OBJECTIVES: The objective of this study was to obtain and analyze qualitative data that described the barriers and facilitators in a cancer center’s catchment area. A further objective was to use the assessment to plan a comprehensive approach to cancer prevention and control activities in the region. METHODS: Extensive qualitative data were gathered from 32 key informants in the 13 county catchment area. We used the Warnecke Model for Analysis of Population Health and Health Disparities to analyze the qualitative data. We coded factors affecting cancer prevention and control using a directed content analysis approach guided by the Warnecke Model. RESULTS: Four outcome types included fundamental barriers such as political environment and discrimination, gaps in resources, and lack of coordinated activities. Social and physical barriers included distrust, diverse language and cultures, and geographic distance. Individual barriers included lack of system negotiation, health literacy, and poverty. Biological barriers were disparate disease rates in specific groups. CONCLUSION: The analysis and assessment led to the creation of a catchment area wide coalition that used the results to formulate a comprehensive strategic plan to address the barriers in the region.

Land fragmentation and small plots are the main features of the rural environment of Galicia (NW Spain). Smallholding limits land use management, representing a drawback in local forest planning. This study analyzes the potential use of multitemporal Sentinel-2 images to detect and control forest cuts in very small pine and eucalyptus plots located in southern Galicia. The proposed approach is based on the analysis of Sentinel-2 NDVI time series in 4231 plots smaller than 3 ha (average 0.46 ha). The methodology allowed us to detect cuts, allocate cut dates and quantify plot areas due to different cutting cycles in an uneven-aged stand. An accuracy of approximately 95% was achieved when the whole plot was cut, with an 81% accuracy for partial cuts. The main difficulty in detecting and dating cuts was related to cloud cover, which affected the multitemporal analysis. In conclusion, the proposed methodology provides an accurate estimation of cutting date and area, helping to improve the monitoring system in sustainable forest certifications to ensure compliance with forest management plans.
