- The tokamak a configuration variable (TCV) continues to leverage its unique shaping capabilities, flexible heating systems and modern control system to address critical issues in preparation for ITER and a fusion power plant. For the 2019-20 campaign its configurational flexibility has been enhanced with the installation of removable divertor gas baffles, its diagnostic capabilities with an extensive set of upgrades and its heating systems with new dual frequency gyrotrons. The gas baffles reduce coupling between the divertor and the main chamber and allow for detailed investigations on the role of fuelling in general and, together with upgraded boundary diagnostics, test divertor and edge models in particular. The increased heating capabilities broaden the operational regime to include T (e)/T (i) similar to 1 and have stimulated refocussing studies from L-mode to H-mode across a range of research topics. ITER baseline parameters were reached in type-I ELMy H-modes and alternative regimes with 'small' (or no) ELMs explored. Most prominently, negative triangularity was investigated in detail and confirmed as an attractive scenario with H-mode level core confinement but an L-mode edge. Emphasis was also placed on control, where an increased number of observers, actuators and control solutions became available and are now integrated into a generic control framework as will be needed in future devices. The quantity and quality of results of the 2019-20 TCV campaign are a testament to its successful integration within the European research effort alongside a vibrant domestic programme and international collaborations.

- Background: Different indigenous peoples in the Philippines still utilize medicinal plants in treating gynecologic diseases. However, there is a lack of information regarding these medicinal plants used in treating gynecologic conditions in the Philippines. Hence, this systematic review compiled the available literature on medicinal plants used for gynecologic healthcare by various indigenous groups in the Philippines. Methods: Ethnobotanical studies that reported medicinal plants used for gynecologic diseases were obtained from OVID Medline, Scopus, and EBSCO CINAHL. A review of titles, abstracts, and articles was done independently by four reviewers. The quality of the studies was assessed using the quality assessment tool for ethnobotanical studies. Results: A total of 27 studies, including 98 different records, that cited the use of medicinal plants to treat gynecologic diseases were included in the qualitative synthesis. Most ethnobotanical studies were conducted in Northern Mindanao, Central Luzon, and Caraga, Philippines. The most common plant family, genus, and species were Fabaceae, Mimosa, and Mimosa pudica L., respectively. Leaves, roots, and stems were predominantly used, commonly prepared by decoction. Medicinal plants reported in ethnobotanical studies were widely used to treat dysmenorrhea (34 ssp.), irregular menstruation (28 spp.), myoma (four spp.), and infertility (four spp.). A significant proportion of medicinal plants used to treat gynecologic diseases in the Philippines had records of toxicologic (18 spp., 31.03%) or teratogenic (one sp., 1.72%) properties. Other species were reported as both nontoxic and toxic (five spp., 8.62%) and toxic and teratogenic (one sp., 1.72%). However, some were nontoxic or teratogenic (11 sp., 18.97%). In addition, 22 plant species had no data on toxicity or teratogenicity. Conclusion: This systematic review showed that medicinal plants and traditional healing practices are crucial in gynecologic healthcare in the Philippines.

- Background: Medicinal plants are still used in developing countries, including the Philippines, to treat common diseases in the community. Anemia is a common disease encountered in the community. It is characterized by a lower-than-normal level of red blood cell count. This systematic review identified the medicinal plants used for anemia treatment in the Philippines. Methods: The study was conducted based on the PRISMA flow diagram, starting with a data search on electronic databases. The collected studies were screened based on the inclusion and exclusion criteria. The necessary information was extracted from the eligible research papers, and the studies’ quality was assessed through a developed quality assessment tool. Results: A total of 20 ethnobotanical studies on medicinal plants used for anemia treatment were obtained from different provinces within the 12 regions of the Philippines. Most ethnobotanical studies were conducted in Region X (Northern Mindanao), CAR (Cordillera Administrative Region), and Region XIII (CARAGA), Philippines. The most common plant family is Convovulaceae, with nine records (21.95%), followed by Cucurbitaceae, with six records (14.63%), and Moringaceae, with five records (12.2%). The most common plant part used was the leaves. Others involved mixing different plant parts, with fruits and leaves being the most common combination. The most common route of administration utilized was drinking the decoction, followed by eating the plant. Most medicinal plants used to treat anemia in the Philippines had records of toxicologic (four species, 15.38%) or teratogenic (one species, 3.85%) properties. Eight plant species were reported as nontoxic (30.77%). In addition, ten plant species (38.46%) had no data on toxicity or teratogenicity. Conclusion: There were only 20 ethnobotanical studies that documented the use of plants in treating anemia in the Philippines. This study listed several medicinal plants used in treating anemia in the Philippines. However, pharmacological and toxicological studies are still needed to determine their safety and efficacy in treating anemia in the community.
