Abstract: a series of r-(+)-limonene derivatives bearing a substituted thiourea moiety (3-13) and five s-methyl analogs (14-18) were synthesized and evaluated for their in vitro antiproliferative activity against human cancer cell lines. compounds bearing aromatic substituents (3-6) exhibit cytotastic activity in the full panel of cell lines tested, with gi50 values in the range of 2.5 to 24 μmol l-1. compounds 3, 10, 12 and 16 were the most active with gi50 values in the range of 0.41 to 3.0 μmol l-1, against different cell lines.

Abstract: lethality of the extracts of croton floribundus (euphorbiaceae), a medicinal plant from south brazil, and of the kaurenoic acid, an isolated compound, and two of its derivatives against adult biomphalaria glabrata snails, schistosoma mansoni cercariae and artemia salina leach. brine shrimp larvae are reported. both extracts and the isolated compound showed significant molluscicidal and cercaricidal activities and reduced toxicity in brine shrimp assays.

Developing Standards for Language Teacher Education Programs in Indonesia: Professionalizing or Losing in Complexity?
Luciana Luciana
TEFLIN Journal , 2004,
Abstract: Setting standards for language teacher education programs, materials, and evaluation sparks some hope in attempts to improve the quality of the programs. Yet, this very fact augmented by my examination of ten language teacher education programs in Java, Bali, and Lampung (FKIP and PGRI) triggers a critical look at the idea of standard development. In particular, I would like to explore whether it can lead to a better professionalism or we are just lost in the complexity of the standardization itself. This paper consists of four sections. Departing from an overview of language teacher education programs in Indonesia and the theoretical foundations, some major problems in this area are identified. Following this, the discussion is focused on the idea of standard development for language teacher education programs in Indonesia. Eventually, some suggestions are put forth to highlight the need for establishing coherent curriculum framework bridging the two realms of language teacher education and school milieu as well as providing learners with knowledge base that enables them to cope with complex demands of school settings and more essentially, to act as an agent in the social change process.
Antimicrobial Resistance in Enterococcus sp Isolated from Soft Cheese in Southern Brazil  [PDF]

The aim of this research was to study the incidence of antibiotic resistance in 56 Enterococcus strains isolated from dairy products. The identification of enterococci was detected by polymerase chain reaction (PCR) using specific primers to E. faecalis, E. faecium, E. gallinarum and E. casseliflavus, and antibiotic resistance was tested by the disk diffusion method. The most prevalent species was E. faecium with a rate of 58.33%, followed by 27.77% E. faecalis, 11.11% E. casseliflavus and 2.7% E. gallinarum. Distribution of resistance was found in different species. All isolates were susceptible to chloramphenicol, ampicillin, imipenem and amoxicillin/clavulanic acid. In addition, isolates resistant to tetracyclin, nalidixic acid, amikacin, erythromycin, vancomycin and cephalothin were detected. A total of 66.6% of E. faecium and 58.3% of E. faecalis strain were resistant to multiple drugs. The van(A) gene was

Abstract: objective: critically review the availability of life satisfaction assessment to measure the quality of life of adolescents. method: this review included life satisfaction scales just for adolescents. studies from general population, or about the relationship between adolescents and their parents, with health care and with health services were excluded. the following electronic databases were used: medline, lilacs, psycinfo, pubmed and adolec, also included consulting the references of selected articles. results: 22 studies were included based on inclusion and exclusion criteria adopted in the review, which includes nine life satisfaction scales, and two of them were versions from the same author (brief form and adolescent version). one quality of life scale which had life satisfaction domains was included. conclusion: the validity of principals scales were related and the reduce of crosscultural research were observe. the concept of quality of life by life satisfaction instruments is almost new and need to include more studies with cultural and economics differences.
Museus e seus arquivos: em busca de fontes para estudar os públicos
K?ptcke, Luciana Sepúlveda;Pereira, Marcele Regina Nogueira;
História, Ciências, Saúde-Manguinhos , 2010, DOI: 10.1590/S0104-59702010000300014
Abstract: the article explores to what extent historical archives at museums may serve as documental sources in developing audience research. it analyzes the process by which we construct our knowledge of the relation between museums and their different visitors and also contextualizes the emergence of 'audience' as a category and object of study by the social sciences. the article presents luciana sepúlveda k?ptcke and marcelle pereira's guia de fontes primárias: o museu nacional - seu público no século xix e no início do xx (guide of primary sources: the national museum - its audience in the nineteenth and early twentieth centuries), a valuable research tool that can enhance the significance of documental fonds and reveal the nature and import assigned to different audiences by these institutions.
Brief representation of the performance by the following Enterprises Groups: “Objetivo, COC and Positivo” in the districts of S o Paulo state

Educa??o : Teoria e Prática , 2011,
Abstract: This article means to make a brief presentation about the origin f the operation and the insertion into the “paulista” educational market with emphasis in the period from 2001 to 2010 of three big Enterprises Groups, “Objetivo COC and Positivo” as well caracterize the products and services which are part of its “educational systems”. Besides of the performance in the private teaching sector such Groups have stood out for their amplification in the Public System through the use its teaching apostilles system by a significant number of “paulistas” districts. The data refer to a research made by the authors during the development of the researches of scientific initiation. We can observe a lot of similarities in the course and performance of three Groups and a big increasing offer of their “teaching systems”, thus generating consequences such as standardization of teaching contents, standardization of quality and transfer of responsabilities from the public sector to the private sphere.

Monitoring the Short-Term Response to Salt Exposure of Two Genetically Distinct Phragmites australis Clones with Different Salinity Tolerance Levels  [PDF]
Luciana Achenbach, Hans Brix
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.58122

Aims: Two genetically distinct clones of Phragmites australis were used to investigate the immediate response induced by osmotic stress. The study aimed at elucidating if the response time, the inhibition rate and the recovery from salinity stress vary between these two genotypes. The experimental work was conducted at the laboratory of the Institute of Bioscience, Aarhus University, Denmark. Methods: The light-saturated photosynthetic rate (Pmax), stomata conductance (gs) and transpiration rate (E) were measured over different periods of salt exposure (15, 70 and 240 minutes) and at different salt concentrations (20 and 40 parts per thousand salinity). Important findings: The osmotic stress induced stomata closure and reduction of Pmax and E for both clones. The clone-specific responses as measured through physiological parameters were negatively
