How to transform urban institutional green spaces into Ancillary Botanic Gardens to expand informal botanical learning opportunities in cities.

Since many cities lack botanical gardens, we introduced the concept of Ancillary Botanic Gardens (ABG), which builds on the premise that organizations can expand informal botanical learning by adding a secondary function to their institutional green spaces. This study guides the application of the ABG concept in various spatial and functional contexts by offering practical and interpretive tools to organizations who are less used to working with nature but are interested in mitigating urban residents' detachment from nature. Online maps of 220 botanic gardens were reviewed to define types of plant collections and produce an exhaustive list of physical botanic garden elements. The collected information was developed into an ABG field checklist that was tested on three case studies in Lebanon and then used to develop guidelines for ABG establishment. The guidelines and checklist are meant to empower and guide organizations interested in establishing an ABG.

Biodiversity conservation in cities: Defining habitat analogues for plant species of conservation interest.

SYNTHESIS AND APPLICATIONS: The stepwise method was useful in producing informative plant lists and assemblages for planting designs and landscape management; it generated a plant selection palette that is not restrictive and does not enforce a native only policy. It also offered a wide range of potential habitat analogues for M. crassifolia.

The Use of Complementary and Alternative Medicine among Lebanese Adults: Results from a National Survey.

Objective. To examine the prevalence and correlates of Complementary and Alternative Medicine (CAM) use in Lebanon. Methods. A cross-sectional survey was conducted through face to face interviews on a nationally representative sample of 1,475 Lebanese adults. The survey questionnaire explored the sociodemographic and health related characteristics as well as the types and modes of CAM use. The main outcome in this study was the use of CAM during the last 12 months. Results. Prevalence of CAM use was 29.87% with "folk herbs" being the most commonly used (75%). Two out of five CAM users indicated using it as alternative to conventional therapies and only 28.4% of users disclosed the use of CAM to their physician. CAM use was significantly associated with higher income, presence of a chronic disease, and lack of access to needed health care. Lower odds of CAM use were observed among older adults and those with a higher education level. Conclusions. This study revealed a high prevalence of CAM use in Lebanon. Health policy and decision makers need to facilitate proper regulation and integration of CAM into mainstream medicine and educate health care providers and the public alike on the safe and effective use of CAM therapies.

Bioactivity of indigenous medicinal plants against the cotton whitefly, Bemisia tabaci.

Forty-one methanol extracts of 28 indigenous medicinal plant species were tested for their insecticidal bioactivity against cotton whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), adults and second nymphal instars under controlled conditions. This study is within a bioprospection context, in the form of utilizing local plant species as an alternative in sustainable agriculture development. Eighteen and nine plant extracts caused a significant decrease in number of live adult and nymphal whiteflies, respectively, compared to the control. This is the first report for the potential effect on survival of insects for 22 out of 28 tested medicinal plant species. Whole plant extracts of Ranunculus myosuroudes Boiss. and Kotschy (Ranunculaceae), Achillea damascena L. (Asteraceae), and Anthemis hebronica Boiss. and Kotschy (Asteraceae) and leaf extracts of Verbascum leptostychum DC. (Scrophulariaceae) and Heliotropium rotundifolium Boiss. (Borangiaceae) caused both repellent and toxic effects against the adult and second nymphal instars, respectively. Extracts of leaves and stems of Anthemis scariosa Boiss. (Asteraceae) and Calendula palestina Pers. (Asteraceae) were found to be more bioactive against the adult and nymphal instars, respectively, than extracts of other plant parts, such as flowers. Thus, the bioactive extracts of these medicinal plants have the potential to lower whitefly populations in a comprehensive pest management program in local communities, pending cultivation of these medicinal plant species.

Autographa californica M nuclear polyhedrosis virus and cytochalasin D: antagonists in the regulation of protein synthesis.

During infection by the baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV), synthesis of host proteins in IPLB-Sf-21 cells is inhibited. We report here that cytochalasin D (CD), a drug that specifically interacts with actin, behaved as an antagonist in the virus-mediated shutdown of host proteins actin and tubulin. In uninfected cells, CD caused an increase in actin synthesis but had no apparent effect on tubulin synthesis. In infected cells, CD similarly enhanced actin synthesis early in infection and delayed the virus shutoff of actin synthesis by 14 hr. The shutoff of tubulin synthesis was delayed by 8 hr. Addition of CD to infected cells after host protein synthesis ceased resulted in an induction of actin synthesis reversing viral inhibitory effects. Similarly, the removal of CD resulted in virus-induced inhibition of actin synthesis. Treatment of infected cells with CD caused a delay in the onset and/or shutoff of at least five viral proteins and inhibited the amplification of polyhedrin synthesis by at least 8 hr.
