Intraspecific variability of dihydrochalcone, chromenes and benzoic acid derivatives in leaves of Piper aduncum L. (Piperaceae)

Chemical analysis carried out in leaves of 18 specimens of Piper aduncum L. (Piperaceae) occurring at Ripasa Reserve, Araraquara, SP, Brazil indicated two distinct populations when investigated over a period of 14 months (January 2000 to February 2001) and then submitted to cluster analysis. The two groups were characterized by accumulation of prenylated benzoic acids, chromenes and dihydrochalcone, respectively. A total of seven compounds were identified by HPLC analysis and compared with standards including two prenylated benzoic acid [aduncumene (1) and 3-(3′-7′-dimethyl-2′-6′-octadienyl)- 4-methoxy-benzoic acid (5)], four chromenes [methyl 2,2-dimethyl-8-(3′- methyl-2′-butenyl)-2H-1-chromene-6-carboxylate (4), methyl 2,2-dimethyl-2H-1-chromene-6-carboxylate (2b), methyl 8-hydroxy-2,2-dimethyl-2H- 1-chromene-6-carboxylate (3) and 2,2-dimethyl-2H-1-chromene-6-carboxylic acid (2a)] and one dihydrochalcone [2′,6′-dihydroxy-4′-methoxy- dihydrochalcone (6)]. © 2009 Academic Journals.

A ótica do usuário na avaliação da qualidade do programa de atenção odontológica à gestante

Objective: To evaluate the pregnant women's perception of the FOA-UNESP's Pregnant Women Dental Care Program (Araraquara, SP, Brazil). Method: The sample included 75 pregnant women and used a questionnaire with 16 closed questions, containing variables grouped in the following categories: the didactic-psychological meetings, clinical treatment, professional's profile, clinical facility, fear/confidence in the treatment, and learning. Except for the variables fear/confidence in the treatment and learning, to which 'yes' or 'no' answers were attributed, the remaining variables were attributed answers varying from weak to excellent. The questionnaire pretested in a pilot-study and applied after informed consent was obtained from all pregnant women treated between 2005 and 2006. Results: Most women rated as excellent the information addressed during the didactic-psychological meetings (81.1%), the clinical treatment (90.6%), the professional as to personal appearance, kindness and attention (88.7%, 96.2% and 90.6%, respectively), and the clinical facility as to cleanness, ventilation and comfort (92.5%, 86.8% and 90.6%, respectively). Most of them stated to feel confident (96.2%) and have no fear (86.8%) during the treatment and also affirmed having learned new information in the didactic-psychological meetings of the program (92.5%). Conclusion: The services and actions developed in the program have reached successful outcomes, providing health to the pregnant women and their forthcoming babies.

Escala de ansiedade odontológica: Reprodutibilidade das respostas dadas em entrevistas telefônicas e pessoais

Objective: To estimate the intra-examiner reproducibility of the Dental Anxiety Scale (DAS) when applied by phone and personal interviews and to evaluate the association between the level of anxiety and the factors of interest. Method: The participants were 50 individuals (n=38 females) with mean age of 23.9±8.9 years, living in the city of Araraquara, SP, Brazil. The volunteers answered the DAS by means of two phone interviews with one-week interval between them. After 30 days, the DAS was applied to the same participants by means of personal interviews at two moments with one-week interval between them. Intra-examiner reproducibility was determined using Kappa (K) statistics by point and by confidence interval. Results: The intra-examiner agreement for the level of anxiety was 0.82 (0.75-0.90) for the phone interview and 0.69 (0.60-0.79) for the personal interview. Two of the DAS questions presented statistically significant difference in the intra-examiner reproducibility, with better agreement for the answers given by the participants during phone calls. The prevalence of dental anxiety in the sample was 92.0%, in such a way that 70.0%, 18.0% and 4.0% of them presented low, moderate and exacerbated anxiety. Conclusion: The classification of the individuals according to the anxiety level performed by means of phone and personal interviews presented statistically similar agreement. However, there was better agreement with phone calls for the questions referring to anxiety in the dental office's waiting room and during preparation of the motor for use in the dental treatment.

Influência das concepções europeias na formulação do pensamento urbanístico paulista

This article aims to present a list of the main influences experimented by architects and urbanists to formulate an urban thought of Sao Paulo City. This way, it will be discussed the main issues raised between the first decades of the XX Century until the 1950s, trying to foresee how the engineers and architects worked to incorporate the urbanistic proposals from Europe and the United States. On the first three sections of this article, it will be presented the concepts that effectively impacted the paulista urban thought of the first half of the XX Century: Sanitarism, the pendulum design: between the Mesologic Theory and the Microbian Theory; Camillo Sitte's historicist formulation; Howard Garden Town and the French experience. Our analysis was formulated by having as a reference a broad and systematic literature, documents stored at Arquivo Histórico Municipal de Araraquara (SP), visits to Faculdade de Arquitetura e Urbanismo da USP Library and to Faculdade de Ciências e Letras da Unesp, Araraquara. The analysis shows that two urbanistic planner streams that happened in São Paulo State were clearly influenced by the conceptions that led the urbanistic debates in the first half of the XX Century. So, these conceptions compose a painting of the urban interventions in São Paulo City.
