The Impact

Medicinal plants are insufficiently studied and almost endless. The use of phytomedication enables reduce the impact of xenobiotics on animals organism through the natural origin of active compounds and associated and auxiliary substances smoothing the basic action and prevent the manifestation of side effects. One of such plants the possibility of using in veterinary practice is still insufficiently studied is mock–orange. Considering on the important role of phenolic compounds in the metabolic regulation of plant and diversity of impact of these substances on organism of animals and humans, in leaves of mock–oranges different cultivar was identified the content of phenolic secondary metabolites to identify the prospects for their further using in veterinary medicine. The qualitative reaction with the Wilson reagent, solution of iron (III) chloride and by cyanidin reaction in extracts from mock–orange leaves was established the presence of phenolic compounds. Further phytochemical investigations established that the content of phenols in the investigated extracts is between 33.0 ± 0.48 to 107.1 ± 0.91 mg/g (in Philadelphus L. 'Avalanche'). The content of flavonoids in alcohol extracts from leaves of different species of mock–oranges varies from 5.3 ± 0.41 to 10.6 ± 0.41 mg/g. Greatest quantity of flavonoids at relatively of low content of phenols contained in the preparation from leaves of Philadelphus coronaries 'Nana '(mock–orange dwarf), the use of which, along with Philadelphus L. 'Avalanche' can be perspective in medical and veterinary practice, considering on the high concentration of phenols and flavonoids and coumarins in these mock–oranges breed.

Microalgae Growth

In this research, the capacity of biodegradation of phenolic compounds using the microalgae Chlamydomonas reinhardtii was evaluated, as well as the impact of the contaminant on the growth of the microalgae. The bioassays consisted on three phenol concentrations: 25 mgL/L, 50 mgL/L and 100 mg/L and a control solution. Bioremediation rates of approximately 99% were obtained, showing no significant difference between medium and high concentration bioassays. A good microalgae growth rate was obtained for the tests at low and medium concentration, they were above the control bioassay, but the high concentration bioassay showed an inhibition in the cell growth, this one presented growth below the control bioassay. The use of the microalgae Chlamydomonas reinhardtii in bioremediation processes of phenolic effluents, whose concentrations are below 100 mg/L, is proposed for future research.

The Impact

This review reports recent knowledge on the role of ingredients (barley, hop and yeasts), including genetic factors, on the final yield of phenolic compounds in beer, and how these molecules generally affect resulting beer attributes, focusing mainly on new attempts at the enrichment of beer phenols, with fruits or cereals other than barley. An entire section is dedicated to health-related effects, analyzing the degree up to which studies, investigating phenols-related health effects of beer, have appropriately considered the contribution of alcohol (pure or spirits) intake. For such purpose, we searched Scopus.com for any kind of experimental model (in vitro, animal, human observational or intervention) using beer and considering phenols. Overall, data reported so far support the existence of the somehow additive or synergistic effects of phenols and ethanol present in beer. However, findings are inconclusive and thus deserve further animal and human studies.

The Impact

Biological rhythms can influence the activity of bioactive compounds, and at the same time, the intake of these compounds can modulate biological rhythms. In this context, chrononutrition has appeared as a research field centered on the study of the interactions among biological rhythms, nutrition, and metabolism. This review summarizes the role of phenolic compounds in the modulation of biological rhythms, focusing on their effects in the treatment or prevention of chronic diseases. Heterotrophs are able to sense chemical cues mediated by phytochemicals such as phenolic compounds, promoting their adaptation to environmental conditions. This is called xenohormesis. Hence, the consumption of fruits and vegetables rich in phenolic compounds exerts several health benefits, mainly attributed to the product of their metabolism. However, the profile of phenolic compounds present in plants differs among species and is highly variable depending on agricultural and technological factors. In this sense, the seasonal consumption of polyphenol-rich fruits could induce important changes in the regulation of physiology and metabolism due to the particular phenolic profile that the fruits contain. This fact highlights the need for studies that evaluate the impact of these specific phenolic profiles on health to establish more accurate dietary recommendations.

Abstract Factors that determinated phytosanitarian chernozems worsening was examined in the space between Prut and Nistru in the global phenomenon of agricultural soil exhaustion. It was established anthropological and natural origin (pedofunctional) phenomenon of studied exhaustion chernozems exhaustion. The main cause of cernozems exhaustion is to reduce the dominant role of the training and accumulation of humus. Through this prism of ideas, soil exhaustion and phytosanitarian worsening is inherent to agricultural system currently practiced. The impact mitigating of this process involves the bioenergy resources sustainable management involved in anthropogenic pedogenesis.

General Climate

Two studies examined the impact of macrolevel symbolic threat on intergroup attitudes. In Study 1 (N = 71), participants exposed to a macrosymbolic threat (vs. nonsymbolic threat and neutral topic) reported less support toward social policies concerning gay men, an outgroup whose stereotypes implies a threat to values, but not toward welfare recipients, a social group whose stereotypes do not imply a threat to values. Study 2 (N = 78) showed that, whereas macrolevel symbolic threat led to less favorable attitudes toward gay men, macroeconomic threat led to less favorable attitudes toward Asians, an outgroup whose stereotypes imply an economic threat. These findings are discussed in terms of their implications for understanding the role of a general climate of threat in shaping intergroup attitudes.
