Supercritical Extraction from Vinification Residues: Fatty Acids, α-Tocopherol, and Phenolic Compounds in the Oil Seeds from Different Varieties of Grape

Supercritical fluid extraction has been widely employed in the extraction of high purity substances. In this study, we used the technology to obtain oil from seeds from a variety of grapes, from vinification residues generated in the Southern region of the state of Rio Grande do Sul, Brazil. This work encompasses three varieties of Vitis vinifera (Moscato Giallo, Merlot, and Cabernet Sauvignon) and two of Vitis labrusca (Bordô e Isabel), harvested in 2005 and 2006. We obtained the highest oil content from Bordô (15.40%) in 2005 and from Merlot (14.66%), 2006. The biggest concentration of palmitic, stearic, and linoleic acids was observed in Bordô, 2005, and in Bordô, Merlot, and Moscato Giallo, 2006. Bordô showed the highest concentration of oleic acid and α-tocopherol in both seasons too. For the equivalent of procyanidins, we did not notice significant difference among the varieties from the 2005 harvest. In 2006, both varieties Isabel and Cabernet Sauvignon showed a value slightly lower than the other varieties. The concentration of total phenolics was higher in Bordô and Cabernet Sauvignon. The presence of these substances is related to several important pharmacological properties and might be an alternative to conventional processes to obtain these bioactives

Building a Portuguese Coalition for Biodiversity Genomics

The diverse physiography of the Portuguese land and marine territory, spanning from continental Europe to the Atlantic archipelagos, has made it an important repository of biodiversity throughout the Pleistocene glacial cycles, leading to a remarkable diversity of species and ecosystems. This rich biodiversity is under threat from anthropogenic drivers, such as climate change, invasive species, land use changes, overexploitation or pathogen (re)emergence. The inventory, characterization and study of biodiversity at inter- and intra-specific levels using genomics is crucial to promote its preservation and recovery by informing biodiversity conservation policies, management measures and research. The participation of researchers from Portuguese institutions in the European Reference Genome Atlas (ERGA) initiative, and its pilot effort to generate reference genomes for European biodiversity, has reinforced the establishment of Biogenome Portugal. This nascent institutional network will connect the national community of researchers in genomics. Here, we describe the Portuguese contribution to ERGA’s pilot effort, which will generate high-quality reference genomes of six species from Portugal that are endemic, iconic and/or endangered, and include plants, insects and vertebrates (fish, birds and mammals) from mainland Portugal or the Azores islands. In addition, we outline the objectives of Biogenome Portugal, which aims to (i) promote scientific collaboration, (ii) contribute to advanced training, (iii) stimulate the participation of institutions and researchers based in Portugal in international biodiversity genomics initiatives, and (iv) contribute to the transfer of knowledge to stakeholders and engaging the public to preserve biodiversity. This initiative will strengthen biodiversity genomics research in Portugal and fuel the genomic inventory of Portuguese eukaryotic species. Such efforts will be critical to the conservation of the country’s rich biodiversity and will contribute to ERGA’s goal of generating reference genomes for European species.info:eu-repo/semantics/publishedVersio

Pain at insertion of the levonorgestrel-releasing intrauterine system in nulligravida and parous women with and without cesarean section

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Background: Despite the high contraceptive effectiveness and noncontraceptive benefits of the levonorgestrel-releasing intrauterine system (LNG-IUS) in nulligravidas, there are still concerns related to the use of this device. Pain at insertion is one of the limitations to the increased use of intrauterine contraceptives. The aim of the study was to evaluate the ease of insertion and occurrence of pain at insertion of the LNG-IUS in nulligravidas (women who never became pregnant) compared to parous women with and without cesarean section (c-section). We also assessed the difficulty at insertion in each group. Methods: Three groups of new acceptors of the LNG-IUS were studied: one with 23 nulligravida women, one with 28 parous women who had undergone at least one c-section and one with 23 parous women who had no previous c-section. Pain at insertion was evaluated by using a pain visual analogue score (VAS). The ease of insertion was defined as easy or difficult by health care providers (HCPs) and classified according to the cause of difficulty: tight cervix, anatomically distorted uterus or pain. Results: Almost all women reported pain at insertion, regardless of parity and form of delivery. The mean VAS was 6.6 for nulligravida women, 5.2 for parous women with c-section and 5.9 for parous women with no c-section. Although 93% of the women reported pain at insertion, they also reported a willingness to insert a new LNG-IUS again if needed. The most common difficulties were a tight cervix in nulligravidas, an anatomically distorted uterus in parous women with c-section and pain in parous women without c-section. There was no failure of insertion in any group. HCPs reported that it was easier to perform insertion in parous women who had undergone only vaginal deliveries than nulligravid women or parous women with a prior c-section. Conclusions: Although almost all women reported pain at insertion, they also reported a willingness to insert a new LNG-IUS if needed. This attitude reflects high satisfaction with the LNG-IUS. The type of difficulty at insertion was related to parity and type of delivery. The LNG-IUS was able to be inserted in all women; however, it was easier to do in parous women without c-section than nulligravid women or those with a prior C-section. (C) 2013 Elsevier Inc.
