Objective: To assess the knowledge of medicinal plants and herbal medicines by Community Health Agents (ACS) in a ESF municipality Ijuí/RS. Method: Cross-sectional study, quantitative and qualitative, with 13 ACS. Data collection occurred in April 2014, and the analysis of quantitative data was done using descriptive statistics. The qualitative data were presented through the Collective Subject Discourse. Results: The main understanding of ACS on herbal medicine is related to the use of medicinal plants. Everyone agrees on the availability of plants and herbal medicines in the NHS, and provide information as to the mode of preparation and storage plants. Also believe that the incorrect use of plants can cause health hazards. Conclusion: There is a lack of knowledge about herbal medicine for ACS. Herbal medicine can and should be considered as a field of interaction of knowledge and practice that values and considers cultural resources, practices and local knowledge, with the involvement of the professional health care team.

http://www.scielo.br/ ; Copper is an essential metal for normal plant growth and development, although is also potentially toxic. Copper participates in numerous physiological processes and is essential cofactor for many metalloproteins, however, problems arise when excess copper is present in cells. Excess copper inhibits plant growth and impairs important cellular processes (i.e., photosynthetic electron transport). Since copper is both an essential cofactor and a toxic element, different strategies with a complex network of metal trafficking pathways have been evolved in plants to appropriately regulate its homeostasis as a function of changing environmental copper level. Such strategies must prevent accumulation of the metal in the freely reactive form (metal detoxification pathways) and to ensure proper delivery of this element to target metalloproteins. The mechanisms involved in the acquisition of this essential micronutrient have not been clearly defined although a number of genes have been recently identified which encode potential copper transporters. This review gives a briefly overview of the current understanding of main features concerning copper toxicity and tolerance in plants as well as information of recent findings on copper trafficking including copper detoxification factors, copper transporters and copper chaperones. ; This work was supported by the Aragón Government (Grant P015/2001) and GC DGA 2002 program of the Gobierno de Aragón. ; Peer reviewed

The tremendous increase in migrations and diasporas of human groups in the last decades are not only bringing along challenging issues for society, especially related to the economic and political management of multiculturalism and culturally effective health care, but they are also creating dramatic changes in traditional knowledge, believes and practices (KBP) related to (medicinal) plant use. The contributors to this volume - all internationally recognized scholars in the field of ethnobiology, transcultural pharmacy, and medical anthropology - analyze these dynamics of traditional knowledge in especially 12 selected case studies. Ina Vandebroek, features in Nova's "Secret Life of Scientists", answering the question: just what is ethnobotany?

La démonstration de la validité des principes et des méthodes de la théorie de l'alimentation minérale équilibrée des végétaux, donnée pour la plante entière dans une note précédente, est étendue ici aux parties de la plante (feuilles, racine) et la quantité de sucre élaborée par plante.

This article is a report on Deni ethnobotanical terms and their indigenous speakers' classification/taxonomy collected from two speakers in 1993 at Porto Velho, nly Rondônia. The transcriptions are believed to be phonologically accurate, but the work reported on is the only work I have done on Deni, so occasional errors may be present.

Plant tissue and organ culture has been extensively used from the beginning of the XX century for the study and comprehension of some primary biological mechanisms such as morphogenesis. However, with the increasing demand of the market for novel products derived from plants, in vitro culture became a reliable technique for the mass production of plant material. Moreover, the potential to use this technique for the production of some bioactive compounds, such as phenolic compounds, is immense since it allows the manipulation of the biosynthetic routes to increase the production and accumulation of specific compounds. This work intends to make a brief historical review of in vitro culture, highlighting its use for the production of bioactive compounds. Also, emphasizes the importance of phenolic compounds for the consumer as well reviews the metabolic pathways involved in its production in plant cells. Furthermore, it was carried out a comprehensive study on the work developed for the production of plant phenolic compounds in in vitro cultures, as well as on the type of elicitors used to increase of the same production; also a brief highlighting of the phenolic compounds which serve as elicitors. There are numerous reports directed to the production of phenolic extracts in in vitro plant cultures, however there is a lack in the production of individual phenolic compounds mainly due to the complexity of the biosynthetic routes and extraction procedures. Elicitation procedures are often used to increase the production of phenolics, archieving in most cases higher yields than in non-elicitated cultures. The increasing production of bioactive phenolic extracts/compounds allows for their further applicability, namely in the industry of functional foods or in pharmaceutical/medical fields. ; The authors are grateful to Fundação para a Ciência e a Tecnologia (FCT, Portugal) for financial support to CIMO (strategic project PEst-OE/AGR/UI0690/2014) and M.I.
