Evaluation of four traditional Romanian medicinal plants as wound healing agents
Achillea millefolium L., Hyssopus officinalis L., Equisetum arvense L. and Echinaceea purpurea L,. are four medicinal plants traditonally used in Romania for treatment of skin disorders and wound healing. In order to suport their use for new plant derived products the aim of this study was to evaluate their potential to stimulate the wound healing process. We investigated the four herbal extracts by HPLC-MS for the presence of polyphenolic compounds,

We tested the enemy hypothesis for gall morphology on a model system comprising two Diplolepis rose gall wasp species and their associated parasitoids. The enemy hypothesis predicts both that gall traits will influence parasitoid attack rates within species, and that galls with contrasting morphologies will support different parasitoid communities. This hypothesis is supported by studies at both intraspecific and broader taxonomic levels (i.e. between

AIMS/HYPOTHESIS: Tissue-specific amplification of glucocorticoid action through 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) affects the development of the metabolic syndrome. Hexose-6-phosphate dehydrogenase (H6PDH) mediates intracellular NADPH availability for 11β-HSD1 and depends on the glucose-6-phosphate transporter (G6PT). Little is known about the tissue-specific alterations of H6PDH and G6PT and their contributions to local glucocorticoid
Read moreThe Environmental Effects and Intra-Industry Trade
The present article analyses the United States’ environmental impact on agriculture intra-industry trade (IIT). The results indicate there is a negative correlation between carbon dioxide emissions and intra-industry trade. According to the literature, i.e. this type of trade uses less pollution technology. In addition, we have found that emissions increase with the level of production. The economic size has a positive influence on carbon dioxide

The goal of this study is to provide some empirical evidence for the existence of a positive relationship between urbanization - as a key component of modernization processes – and democracy, on a dataset set of 56 developing countries covering a time span between 1982 and 2007. The research hypothesis is that developing countries tend to be more democratic at higher levels of urbanization. We tested this hypothesis in an GMM-System methodological

This paper investigates the relationship between intra-industry trade (IIT), horizontal IIT, vertical IIT (VIIT) and immigration flows using a gravity model for the period 1995-2008 amongst Portugal and European Union’s Member States (EU-27). Using a panel data approach, the results show a positive correlation between immigration and IIT. These outcomes indicate that the immigration can reduce transaction costs between home and host country. We
