The correct use of plants for therapeutic purposes requires selection of those showing efficacy and safety based on the popular tradition and/or scientific validation. Bidens pilosa L. is a species that widely occurs in tropical regions and is known in Brazil as "picão-preto". Four agents from the Health Pastoral Service were identified in the region of Criciuma, Santa Catarina State, for their popular knowledge of Bidens pilosa. The study was conducted by means of interview which provided data concerning the knowledge of "picão preto", handling, used plant part, plant/solvent proportion, preparation methods, administration route/dosage, indication and restrictions. The pharmaceutical form, as well as the posology, was significantly variable. Analysis of the collected data showed anti-inflammatory action as the main therapeutic indication.

There are 230 to 240 knownBidensspecies. Among them,Bidens pilosais a representative perennial herb, globally distributed across temperate and tropical regions.B. pilosahas been traditionally used in foods and medicines without obvious adverse effects. Despite significant progress in phytochemical and biological analyses ofB. pilosaover the past few years, comprehensive and critical reviews of this plant are anachronistic or relatively limited in scope. The present review aims to summarize up-to-date information on the phytochemistry, pharmacology, and toxicology ofB. pilosafrom the literature. In addition to botanical studies and records of the traditional use ofB. pilosain over 40 diseases, scientific studies investigating the potential medicinal uses of this species and its constituent phytochemicals for a variety of disorders are presented and discussed. The structure, bioactivity, and likely mechanisms of action ofB. pilosaand its phytochemicals are emphasized. Although some progress has been made, further rigorous efforts are required to investigate the individual compounds isolated fromB. pilosato understand and validate its traditional uses and develop clinical applications. The present review provides preliminary information and gives guidance for further basic and clinical research into this plant.

The electromagnetic inference is an issue from decades, where working for a better shielding material is still on-going. The purpose of this study is to review the existing methods in the formation of graphene, metal and polymer-based composites. Study indicates that in graphene and metal-based composites, the utilization of alternating deposition method showed the highest shielding effectiveness, whereas, in polymer-based composite, the utilization of chemical vapor deposition method showed highest shielding effectiveness. However, this review reveals that still there is a gap in the literature in terms of the selection of the method. Although there are various available methods which researchers adopt as per their convenience, none of the studies makes a comparison of the methods to form a similar composite. Therefore, as a future gap researcher needs to adopt various methods to form a single composite and then make a comparison of shielding effectiveness. This act will be useful for future researchers to select the appropriate method.

The traditional use of medicinal plants for treatment of infectious diseases by an indigenous Mbyá-Guarani tribe from South Brazil was assessed by evaluating the antibiotic and antibiofilm activities against relevant bacterial pathogens. Aqueous extracts from 10 medicinal plants were prepared according to indigenous Mbyá-Guarani traditional uses. To evaluate antibiotic (OD600) and antibiofilm (crystal violet method) activities, Pseudomonas aeruginosa ATCC 27853, Staphylococcus epidermidis ATCC 35984 and seven multi-drug resistant Klebsiella pneumoniae carbapenemase (KPC)-producing bacterial clinical isolates were challenged with the extracts. Furthermore, the susceptibility profile of KPC-producing bacteria and the ability of these isolates to form biofilm were evaluated. The plants Campomanesia xanthocarpa, Maytenus ilicifolia, Bidens pilosa and Verbena sp. showed the best activity against bacterial growth and biofilm formation. The majority of KPC-producing isolates, which showed strong ability to form biofilm and a multidrug resistance profile, was inhibited by more than 50% by some extracts. The Enterobacter cloacae (KPC 05) clinical isolate was the only one resistant to all extracts. This study confirms the importance of indigenous traditional medicinal knowledge and describes for the first time the ability of these plants to inhibit biofilm formation and/or bacterial growth of multi-drug resistant KPC-producing isolates.

Titanium is a primary metallic biomaterial widely used in dental implants because of its favorable mechanical properties and osseointegration capability. Currently, increasing interests have been taken in the interaction between titanium implant surface and surrounding bone tissue, particularly in surface topographical aspect. There are currently several techniques developed to modify surface topographies in the world market of dental implant. In this review, state of titanium implant surfaces in topographical aspect is presented from relatively smooth surfaces to rougher ones with microtopographies and/or nanotopographies. Each surface is summarized with basic elaborations, preparation methods, mechanisms for cellular responses and current availabilities. It has been demonstrated that rough surfaces evolving from micro- to nano-scale, especially hierarchical micro-and nanotopographies, are favorable for faster and stronger osseointegration. Further experimental and clinical investigations will aid in the optimization of surface topography and clinical selection of suitable implants.

Cashew (Anacardium occidentale L.) is an emerging crop suited to tropical regions of Australia. To be viable on world markets, Australian cashews must be more productive and of higher quality than competing products. Since these characteristics are not exhibited consistently by existing varieties, an improvement program was initiated. This paper reports on the evaluation of 2 sets of hybrids produced in 1991 and 1992, which were planted on commercial cashew orchards in the Northern Territory and Queensland and were assessed in terms of yield and quality during 1998 and 1999.

Dental pathologies can be caused by plaque-forming bacteria and yeast, which reside in the oral cavity. The bacteria growing in dental plaque, a naturally occurring biofilm, display increased resistance to antimicrobial agents. The objective was the evaluation of a preclinical assay of medicinal plants of the semiarid region from the northeast against oral pathogenic microorganism, aiming at bioprospecting a new product. The selection of plant material for this study was based on the ethnobotanical data on the traditional use of plants from the semiarid region. The thirty extracts were subjected to the determination of antibiofilm activity against gram-positive, gram-negative bacteria and yeast. The hydroalcoholic extract which showed positive antibiofilm activity against most of the microorganisms tested in agar diffusion assay was further tested for the determination of minimum inhibitory concentration (MIC) and Bioassay withArtemia salina. Plant samples tested in this study exhibited good antibiofilm activity for the treatment of oral problems. TheSchinopsis brasiliensisshowed greater activity forPseudomonas aeruginosaandStaphylococcus aureus, but toxicity againstArtemia salina.

Among all types of cancer encountered in women, breast cancer is the most prevalent, with the highest mortality rate. An increased survival rate is closely related to early diagnosis, the use of high performing screening methods and of selective and adequate treatments. By using the nanotechnologies, the therapeutic effectiveness of the drugs may be improved by a controlled release of the active substances to the tumoral site. The aim of this review is to present the current state of knowledge and to mention the new treatment trends in breast cancer, focusing on a pharmaceutical form that, thanks to its advantages, is already used in the therapy of this disease – the polymeric micelles. Several examples of anticancer agents loaded polymeric micelles are mentioned, illustrating the preparation methods and the current state of clinical studies in which polymeric micelles are used.
