Opierając się na etnograficznych badaniach terenowych przeprowadzonych w centrum leczenia uzależnień Via da Paz, niniejszym artykule analizuję relację między koncepcjami trzeźwości i rzeczywistości. Paz położone jest brazylijskiej Amazonii. Centrum łączy swych praktykach leczniczych rytuały religii União do Vegetal z metodami psychoterapeutycznymi wywodzącymi przede wszystkich filozofii 12 krok...

Vg1, a member of the transforming growth factor-beta family involved in mesoderm induction, is translated subsequent to the localization of its mRNA to the vegetal pole of Xenopus oocytes. Whereas the localization of Vg1 mRNA is known to be directed by the 3' untranslated region (UTR), the basis of its translational regulation is unknown. We show here that the 3' UTR of Vg1 causes translational...

The authors assessed 23 subjects immediately before and six months (27.5 weeks) after their first ayahuasca experience in an urban Brazilian religious setting, either Santo Daime (N = 15) or União do Vegetal (N = 8). Measures included scores on instruments assessing psychiatric symptoms, personality variables and quality of life. Independent variables were the frequency of ayahuasca use through...

Recently, we presented evidence that protein kinase C (PKC) is involved in mediating the endogenous signals that induced competent Xenopus ectoderm to differentiate to neural tissue. We report here that PKC is already strongly activated in neural-induced ectoderm from midgastrula embryos and that this activation runs parallel with an increase in the level of inositol phosphates. We further iden...

Mining activities have caused serious heavy metal pollution in soil and water resources. The weathering mullock and mining tailings transport the heavy metal in polluted areas into ambient soil, rivers, and groundwater, which destroys the surrounding ecosystem. The menace of heavy metal elements in minerals can lead to botanical variety and impact vegetal growth. With the development of remote ...

mRNAs concentrated in specific regions of the oocyte have been found to encode determinants that specify cell fate. We show that an intermediate filament fraction isolated from Xenopus stage VI oocytes specifically contains, in addition to Vg1 RNA, a new localized mRNA, Xcat-2. Like Vg1, Xcat-2 is found in the vegetal cortical region, is inherited by the vegetal blasomeres during development, a...

Qualitative research was conducted in Brazil among 28 ayahuasca-consuming adolescents members of the União do Vegetal Church, and 28 adolescents who never used ayahuasca. They were compared on a number of qualitative variables, including vignettes measuring moral and ethical concerns. Psychocultural studies utilizing co-occurences of variables in the realm of qualitative studies are useful in u...

In Xenopus an early morphological marker of mesodermal induction is the elongation of the mesoderm at the early gastrula stage (Symes and Smith, 1987). We show here that the elongation of equatorial (marginal) tissue is dependent on protein synthesis in a mid blastula, but has become independent of it by the late blastula stage. In animal caps induced to become mesoderm, the time when protein s...

Background & Objectives: The implementation of pest control strategies is essential for reducing food waste and providing fresh safe food product. However, the excessive and uncontrolled usage of pesticides have caused serious environmental and health problems. The aim of this study was to evaluate the level of pesticide residues in food products in Iran via exploring the relevant published wor...
